ACTIVITY REPORT 2010-2011-2012
PREFACE
In the last three years the Institute for Scientific Interchange Foundation went
through several major transformations. The first and most visible one is the change of
its physical space. At the end of 2011, the institute has moved from the historical
location of Villa Gualino to the new location downtown in via Alassio. The new building
has been shaped to address the needs of an Institute increasingly looking for
openness, collaborations, and a modern environment able to foster an ever-increasing
dialogue with the many collaborating institutions in the city of Turin.
Analogously, the research vision and activities of ISI did not stand still. The ISI
research is undoubtedly rooted in the area of complex systems science, a field that
the Foundation has contributed to shape for more than two decades. In the last three
years however, the field of complexity science has entered a new stage of its life. This
is a stage of maturity in which complex systems science is finally generating
applications and quantitative results that allow us to deal with problems that have a
huge impact on our lives such epidemics, systemic risks, and the emergence of social
collective behavior. A key factor in this shift of gears is to be found in the big data
revolution that is finally providing the necessary data, numerical experiments and
validation finally adding an "applied" dimension to complex systems. The ISI has
faced this new challenge by focusing on Data Science with the creation of specific
laboratories and initiatives.
At ISI however Data Science goes well beyond technical issues of gathering data from
"sensors" or programming issues of data crawlers. It also goes beyond the classical
statistical analysis. The focus is on identifying new empirical laws emerging from
massive data sets and addressing the related "How?" question, i.e. on conceptually
new scientific methods for analyzing and synthesizing these laws. Data Science wants
to recognize the picture that is hidden in these massive data streams, to predict its
occurrence in a statistical sense, and to control it. But ISI also wants to go further, to
the "Why?" question, by linking these findings to theoretical concepts in a broader
sense, to understand their origin and their impact.
We do not forget however the importance of the application's side of the Institute
research. We live in an interconnected world where novel ICT technologies are
defining socio-technical networks and systems whose understanding, management
and resilience cannot be achieved without resorting to a complex systems approach.
We are aware that the science that is carried out at ISI finds a natural outlet in
technologies and tools potentially impacting decision making and social systems
analysis in areas ranging from urban development and human mobility to global
health and crisis management. Tools and innovations that must be communicated and
shared with the policy makers, and the various stakeholders outside of the research
community. The research laboratory itself must be hard wired within the life of the
society and the citizen. This awareness has led to another transformation of the
Institute that is restructuring itself to develop and articulate an effective knowledge
exchange vision that levers on a multilevel network of collaborations and
partnerships, both nationally and Internationally.

Although the last years are a living proof that the Institute is undergoing a continuous
and lively transformation, always looking for new challenges and visions, The ISI
foundation has been constantly keeping faith to the core values of the Institute. The
Institute strives to provide science at the highest level possible without constraint;
address the significant challenges of modern society; share the generated knowledge.
All that driven by a culture of freedom that is essential to realize the benefits of
curiosity inspired science.
The above core values are those that shaped the institute three decades ago and
thanks to the president Mario Rasetti they are still vividly impressed in the activities of
the institute. The changes and transformations of the last years have been possible
only because of the commitment of all the staff, researchers, and administrators of
the foundation. The executive director Tiziana Bertoletti is navigating the foundation
through the good and bad weather and bravely setting the course for new
destinations. Ciro Cattuto, the Institute research director, has provided invaluable new
blood and vision to the research activity of the foundation. Anna Piergiovanni, Roberto
Palermo and Enza Palazzo have manned outstandingly the administrative department.
Federico Fornaro carefully manages the Lagrange Project and the many related
activities. The research leaders, Jacob Biamonte, Vittoria Colizza, Gianfranco Durin,
Corrado Gioannini, Paolo Giorda, Vittorio Loreto, Daniela Paolotti, Francesco
Vaccarino, and Stefano Zapperi are those who are relentlessly leading the research
effort at ISI. Along with them more than 50 researchers and staff are making ISI a
place for science and creative thinking. There is no way to thank properly all of them
but saying that ISI is only because of their talent. Finally we have to thank and
acknowledge the friendship and support of the many colleagues, visitors,
collaborators, more than 50 each years, who have contributed to create the
exceptional atmosphere of ISI.
ISI is having its 30th birthday this year. The institute has gone a long way, but surely
the best has yet to come.

GLOBAL AND COMPLEX SYSTEMS SCIENCE
The Foundation is moving ahead the research efforts in consolidated areas of strength
that draw on the experience and knowledge accumulated in the area of complex
systems. By integrating complex systems science with data science and computational
thinking however it is emerging a novel scientific area that aims at providing an
integrated framework for the understanding, analysis and control of social,
technological, and economic systems. It is then possible to see complexity science at
work to the solution of major societal problems such as the containment of emergent
diseases, the design of better energy distribution systems, the planning for traffic-free
cities or the optimization of internet connectivity. The foundation has developed a
research program that aims at building the mathematical, modeling and
computational foundations of the analysis of socio-technical systems as well as to
provide a portfolio of case studies to assess the feasibility and impact of this
framework in real world problems and applications. For this reason in the last two
years the laboratory has branched out its research activities in new areas, especially
strengthening the “data science” component. The research activity is thus articulated
around the following laboratories:

In the following pages we have reported the activities and research focus of each
laboratory. The above research laboratories however are not intended as disciplinary
silos but as thematic group of interest that are all interconnected within the ISI
foundation research structure. Each specific project and initiative is drawing resources
and expertise across the full spectrum of the laboratories human resources. As diverse
the research activities carried out by the Laboratory may seem, the methodological
approach used is the nexus where different fields and problems find their unifying
framework. Techniques borrowed from statistical physics, non-linear dynamics and
computational modeling allow the interdisciplinary approach and cross fertilization
that more than anything else are contributing to the uniqueness and richness of the
Foundation research activities.

COMPLEX NETWORKS AND SYSTEMS LAGRANGE LABORATORY
The research activity of the laboratory aims at the study of systems where a large
number of interacting units give rise to cooperative phenomena, non-trivial patterns
and complex dynamical behavior that cannot be simply inferred from the basic
microscopic interactions. The laboratory is active in scientific areas ranging from social
computational sciences to biological systems to interdisciplinary applications in
information technology, economics and policy making. The division uses large-scale
computational approaches, agent based models, complex networks, non-linear
systems analysis and statistical physics methods to link the microscopic dynamics and
interactions of the constituent elements to the statistical regularities and the
macroscopic properties of the system under study.
COMPLEXITY MATERIAL LABORATORY
The Complexity in Materials group conducts both theoretical and experimental
research into complex phenomena in material science. Particular areas of interest
include: hysteresis and noise in ferromagnetic material, fluctuations in fracture and
plasticity, collective transport in nanostructured materials and deformation in soft
condensed matter physics. We are particularly active in the statistical analysis of the
Barkhausen noise in ferromagnetic thin films and strips, and in the study of
computational models for magnetic domain walls in disordered media. We perform
large scale numerical simulations of lattice models for the fracture and plasticity of
heterogeneous materials. Another subject of current investigation is the topological
properties of deformed colloidal and vortex crystals, which we study by molecular
dynamics simulations.
COMPUTATIONAL EPIDEMIOLOGY LABORATORY
The research activity of the laboratory focuses on i) developing the foundation and
development of the mathematical and computational methods needed to achieve
prediction and predictability of disease spreading in complex techno-social systems; ii)
the development of large scale, data driven computational models endowed with a
high level of realism and aimed at epidemic scenario forecast; iii) the design and
implementation of original data-collection schemes motivated by identified modelling
needs, such as the collection of real-time disease incidence, through innovative web
and ICT applications; v) the set up of a computational platform for epidemic research
and data sharing that will generate important synergies between research
communities and countries. The laboratory proposes a truly interdisciplinary effort
combining complex systems science, computational sciences, mathematical
epidemiology, and ICT technologies.
DATA SCIENCE LABORATORY
The activity of the Data Science Laboratory comprises those research lines that regard
digital traces of human behavior as first-order objects for scientific investigation. The
laboratory has a strong interdisciplinary character, covering research on social media,
on-line social networks, pervasive systems, wireless sensor networks, and applications
to epidemiology. Methodologically, the laboratory extends the traditional toolbox of
complex systems research with techniques from data mining, machine learning, and
with the use of scalable computational infrastructures that can deal with large-scale
records of activity from modern techno-social systems.
At present, the activity of the Data Science Laboratory focuses on two main research
areas. The first research area deals with measuring dynamical networks of human
mobility and proximity in a variety of real-world settings. The SocioPatterns project is
!

the overarching effort that encompasses these activities: it is an international
collaboration, led by the ISI Foundation, that brings together physicists, computer
scientists, electrical engineers and designers under the single objective of designing
and deploying scalable sensor networks that can be used to mine human contacts in
hospitals, schools, conferences, and more. The SocioPatterns project leverages these
data sources to inform research activities on human dynamics, opportunistic
networks, organizational science, and data-driven epidemiology. Applications to
ubiquitous social environments and art/science explorations are also part of the
project.
The second research area, at the interface with computer science, deals with on-line
systems that entangle human behavior and information networks, such as Twitter and
other on-line social networking systems. The research is carried out in collaboration
with the Informatics School of Indiana University and the Computer Science
Department of the University of Torino.
MATHEMATICS OF COMPLEXITY SCIENCE LAB
It has become increasingly evident that the mechanisms governing most social and
technological systems are characterized by very detailed, intricate interactions with
interdependencies among systems. Because of their inherent complexity, which
requires analysis at many scales of space and time, complex systems face science
with novel challenges in observing, describing and controlling them effectively.
Our group aims to bring into the agon of complex system's science some of the more
advanced XX century mathematical theories and techniques. Indeed, one of the
revolutions in the XX century mathematics has been the perspective shift from
focusing on a single object to landscapes of objects and morphism, i.e. agents and
interactions. The goal is twofold: it concerns the development of the necessary
abstract frameworks and it is focused on testing the validity of the proposed approach
on real data. The abstract framework is based on the interplay between algebraic
geometry, algebraic topology, representation theory and statistics, to lay the
foundations for a fresh approach to complex systems theory. In particular our group
focuses on the development and refinement of topological methods to reconstruct the
robust patterns that underlay the structure of complex systems. Within this
framework, we are currently focusing on tailoring the tools of Persistent Homology,
the most recent and efficient ones in computational topology of data clouds, to the
case of complex networks. Thanks to their nature, these methods allow the study of
mesoscopic structures in networks, enhancing and integrating the existing tools
mostly based on statistical mechanical grounds.
INFORMATION DYNAMICS LAB
The activity of the Information Dynamics Laboratory spans several research lines for
which information, whether symbolic or embodied, plays a crucial role. The laboratory
conducts in particular research, both theoretical and experimental, on areas related to
social dynamics in the so-called techno-social systems, which entangle, in a somehow
unpredictable way, cognitive, behavioral and social aspects of human agents with the
structure of the underlying technological systems. Research of the laboratory features
a highly interdisciplinary character, enjoying extensive collaborations with groups in
disciplines as diverse as computer science, engineering, sociology, economics,
psychology and linguistics. More in detail the present activities of the laboratory can
be presented along the following lines.
Opinion dynamics
!
10!
The spread and evolution of opinions is a central topic in sociology, politics and
economics. One is interested in understanding whether and how, starting from each
agent having a different opinion, consensus emerges in which all agents share the
same opinion as opposed to a polarized or fragmented state. We are interested in
particular in investigating the response of a society to exogenous or endogenous
perturbations; under which conditions large-scale opinion shifts are triggered; the role
of the available information in decision making processes; how the possibility of
disagreement makes consensus/polarization/fragmentation emerge; how individual
and collective awareness can be enhanced and how it can trigger behavioral shifts;
how does innovation emerge; how individual behavior is affected by external
pressure, in the form of stress or temporal constraints.
Language dynamics
The study of the self-organization and evolution of language and meaning has led to
the idea that a community of language users can be seen as a complex dynamical
system which collectively solves the problem of developing a shared communication
practice. In this perspective, the theoretical tools developed in statistical physics and
complex systems science acquire a central role for the study of the self-generating
structures of languages. Language is nowadays a hot topic in linguistic, sociology,
cognitive sciences, biology, physics and mathematics. The most natural questions
concern how new conventions (names, categories, grammatical rules), developed
from local interactions among few individuals, can become stable in a whole
population. This occurs when conceptual frameworks are acquired and fine-tuned
through shared sensori-motor experiences and joint actions, and when they are
constantly aligned in dialogue. This suggests a radically different way to look at
language and more generally at emerging communication systems, a perspective
where coherence arises out of this distributed activity in a self-organised way instead
of being “innate” or imposed in a top-down fashion.
Social computation
Recent advances in Information and Communications Technologies (ICT) are enabling
for the first time the possibility of precisely mapping the interactions of large numbers
of people in a reproducible way. In particular the dynamics and transmission of
information along social ties can be nowadays object of a quantitative investigation.
From this point of view the Web is acquiring the status of a platform for "social
computation", able to coordinate and exploit the cognitive abilities of the users for a
given task. In this area we have constructed a brand new platform, Experimental
Tribe (www.xtribe.eu), suitable for the realization of web-based experiments in social
dynamics involving directly individuals into the experimental loop. The benefit is
twofold: on the one hand, it allows virtually any researcher to realize his own
experiment with minimal effort, paving the way of the use of the web as a standard
“laboratory” to perform experiments. On the other hand, it can be a strong “basin of
attraction” for people willing to participate in experiments, making recruitment much
easier than for single-experiment platforms.
ICT driven social dynamics
Nowadays low-cost sensing technologies allow the citizens to directly assess the state
of the environment; whereas social networking tools allow effective data and opinion
collection and real-time information spreading processes. In addition, theoretical and
modeling tools developed by physicists, computer scientists and sociologists have
reached the maturity to analyse, interpret and visualize complex data sets. In this
area the laboratory is coordinating the EveryAware project that integrates all crucial
phases (environmental monitoring, awareness enhancement, behavioural change) in
the management of the environment in a unified framework, by creating a new
!
11!
technological platform combining sensing technologies, networking applications and
data-processing tools; the Internet and the existing mobile communication networks
provide the infrastructure hosting such a platform, allowing its replication in different
times and places. The integration of participatory sensing with the monitoring of
subjective opinions is novel and crucial, as it exposes the mechanisms by which the
local perception of an environmental issue, corroborated by quantitative data, evolves
into socially-shared opinions, eventually driving behavioural changes.
Phylogeny and evolution
While the traditional aim of phylogeny reconstruction is that of classifying a set of
species (viruses, bacteria, languages) sharing a common origin, a more recent trend
is that of uncovering the evolutionary relatedness among those species through the
visualization of their phylogenetic tree. The analysis of statistical features of
phylogenetic trees, e.g., their topological properties, expresses deep information
about the evolutionary process that gave birth to the differentiation of the species. In
this scenario, the challenges are, on the one hand, of developing suitable algorithms
for the analysis of large data-sets, in order to perform robust statistical analyses. On
the other hand, a quantitative analysis of the phylogenetic characteristics of
populations of pathogens (viruses, bacteria), offer a precious validation tool for the
discrimination of theoretical predictions for different evolutionary models. In this area
we are currently working on (i) the modelization of the evolution of the Human
Influenza A virus at the sequence level, to investigate the longstanding puzzle
concerning the relation between the genetic profile of the virus and its interaction with
the host immune system (its antigenic properties), this understanding being crucial
for the control of Influenza outbreaks; (ii) the evolutionary dynamics of Neisseria
meningitidis, a deadly human pathogen, which features an high-level of homologous
recombinations.

Highlights
Data Science Laboratory
The Data Science Laboratory of the ISI Foundation was created during the reporting
period. It has subsumed and expanded the activity of two research lines of the ISI
Foundation focusing, respectively, (i) on the data-driven investigation of time-varying
human interaction networks, and (ii) on the dynamics of collective attention in sociotechnical systems. The Laboratory significantly expanded its operational capabilities
on mining large-scale datasets and provided public contributions to popular opensource technology components. The Laboratory also contributed to (iii) the first
European educational experience on Big Data, helping to shape a Data Science
curriculum that combines mathematical modeling, data mining, and interactive
visualization. In the following we will highlight our work on empirical network of
human proximity for epidemiology and public health.
Time-varying networks of human interaction. The SocioPatterns project
(www.sociopatterns.org) has gained a strong momentum and its data-driven
methodology has been increasingly taken up by diverse research communities. The
Project has successfully measured time-varying contact networks in hospitals and
schools, using wearable proximity sensors, and has released several dataset for public
usage. The data were used to investigate the temporal structure of human
interactions in space and to study the dynamics of epidemic processes in time-varying
networks.
A key problem is the approximation-generalization tradeoff brought forth by the use
of epidemic models simulated over empirical high-resolution networks of human
interactions (figure). The central questions can be phrased as follows: How much
detail do we need in order to achieve a data-driven simulation of an epidemic process
that can inform decision making for public health, e.g., by allowing to design smart
immunization strategies, or optimized schedules for class closure in a pandemic
situation. As digital records of human behaviors become available with higher and
higher resolutions, what parsimonious representations can we devise that strike a
balance between capturing the relevant features of the data and maintaining the
generalizability of the ensuing results to contexts that go beyond the one in which the
data were collected? When is “more detail” helpful, and when does it become “too
much detail”? How do we decide what level of detail is appropriate for predicting a
given property of the system under study? In the domain of epidemic processes on
human contact networks, we have made one step in this direction by showing that
some important features of an epidemic process, e.g., the timing of the epidemic
peak, can be correctly modeled under strong simplifying assumptions, whereas other
quantities, such as the epidemic size, do require the use of high-resolution
information. On the other hand, we have shown that it is possible to devise
parsimonious representations of the data that capture the relevant topological and
weight heterogeneities and drop most of the other high-resolution information,
achieving the same performance of more complex models. Along the same direction,
for the case of structured populations (e.g., hospitals), we have extended the
customary contact matrix representation and introduced a new representation which
is minimally more complex and, in simulation, accurately models epidemic spread in
the structured hospital population.

Sensor networks, quantified human behavior, large-scale data analytics, digital
models of epidemic spreading: all of these directions contribute to a new vision of
“digital epidemiology” that changes the role played by data in public health. The Data
Science Laboratory fully embraces this vision and will further pursue it by advancing
both the underpinning theoretical foundations and the operational data technologies.

Livestock movements
The study of cattle trading systems is crucial for monitoring and understanding the
spreading of emerging epidemics in order to reduce the risks of major outbreaks
posing serious health and economical concerns.
The large dataset of cattle trade movements obtained from the Italian National Bovine
database providing a daily description of the movements of each bovine in Italy has
been described through a dynamical network where the nodes correspond to premises
and a directed link represents a displacement of bovines between two premises.
The large variability and the rapidly evolving daily patterns observed in the trading
system lead, in principle, to an exponential increase of the possible epidemic
scenarios depending on the starting date and the seeding premises of the epidemic.
Such large variations and huge number of degrees of freedom in the system may thus
strongly limit our ability to devise and implement preventing actions for emerging
infectious disease outbreaks. For this reason, through intensive numerical simulations
on the fully dynamic network, we have investigated the role of the initial conditions in
shaping the disease propagation. The analysis of the spreading patterns highlighted
the presence of clusters of premises leading to similar epidemic profiles and peak
times. Such clusters cannot be identified from purely structural or geographical
considerations. By reducing the degrees of freedom in the initial conditions through
clustering also allows us to define a novel method to identify premises characterized
by a large vulnerability, an important knowledge for risk assessment analysis. Indeed,
although the large temporal variability of animals trading routes intrinsically alters the
centrality role of nodes from a given observation time to another, it is possible to
identify sentinel nodes representing premises that are often reached by the disease
and, when detected as infected, are able to provide valuable information on the
seeding farms of the outbreak and thus on the likely spreading path. The proposed
method can be used in order to optimize surveillance systems and define rapid and
efficient containment strategies.

the exchange of batches of bovines between two of them. If an infectious disease
outbreak occurs, the epidemic may propagate spatially, from one animal holding to
another, through the movements of infected animals. Taking advantage of extensive
computer simulations, it is possible to compare different seeds of the outbreak in
terms of the spreading patterns they produce, and group into clusters the nodes that
infect similar sets of premises along their invasion paths. Here, two clusters are
shown as examples, and for each of them three snapshots are reported that
reproduce the invasion paths of nodes belonging to the same cluster.

Validation of H1N1 pandemic model predictions
In 2012, we finalized our work on the validation of the numerical forecasts obtained
by the GLEAM model during the course of the 2009 A/H1N1 pandemic. Our work
appears in the manuscript published by BMC Medicine:
Real-time numerical forecast of global epidemic spreading: case study of
2009 A/H1N1pdm Michele Tizzoni, Paolo Bajardi, Chiara Poletto, José J. Ramasco,
Duygu Balcan, Bruno Gonçalves, Nicola Perra, Vittoria Colizza, Alessandro Vespignani.
BMC Medicine, 10:165 (2012).
In detail, in 2009 we used GLEAM in real-time to generate stochastic simulations of
the pandemic spread worldwide, yielding the incidence and seeding events at a daily
resolution for 220 countries. Using a Monte Carlo Maximum Likelihood analysis, the
model provided an estimate of the seasonal transmission potential during the early
phase of the H1N1 pandemic, and generated ensemble forecasts for the activity peaks
in the northern hemisphere in the fall/winter wave. The forecasts were published in
September 2009, well before the peak weeks of epidemic activity in the northern
hemisphere [1].
Thanks to the availability of incidence data from surveillance systems worldwide, we
compared our predictions against the empirical data collected in 48 countries of the
world, and assessed their robustness with respect to: 1) the peak timing of the
pandemic, 2) the level of spatial resolution allowed by the model; and 3) the clinical
attack rate and the effectiveness of the vaccine.
Real-time predictions on the peak timing were found to be in good agreement with the
empirical data, showing strong robustness to data not accessible in real time (such as
vaccination campaigns adherence, pre-exposure immunity, etc.), whereas these
ingredients affect the predictions for the attack rates. Timing and spatial unfolding of
the pandemic are critically sensitive to the level of mobility data integrated into the
model.
Our results showed that large-scale models can be used to provide valuable real-time
forecasts of influenza spreading, at the cost of high performance computing. Better
quality is achieved depending on the level of data integration, thus advocating for the
need of high quality data in population-based models and of a progressive update of
validated available empirical knowledge to inform the models.

Multistrain epidemics
The PREDEMICS project aims at providing preparedness, prediction and prevention of
emerging zoonotic viruses with pandemic potential. The project foresees the
integration of different disciplines and approaches in order to provide a deep
understanding of the mechanisms underlying disease emergence. In particular the
research focus on the environmental and anthropological factors determining the
ability of viruses to cross the species barriers and become transmissible among
humans, along with the complex biological interactions among multiple virus strains
and the human population that drive the disease dynamics and the virus emergence
and evolution.
During the first year of the project, our research activity has focused on the
competition among multiple virus strains in a spatially structured host population. We
addressed this topic through a general and theoretical perspective. We designed a
theoretical model for the spreading of two pathogens interacting through full crossimmunity in the same population. The model explicitly accounts for spatial structure
and mobility of hosts and is able to provide a clear understanding on the role of
mobility in multi-pathogen competition. Results show that according to the mobility
rate of hosts, competition results in the dominance of either one of the two pathogens
or co-circulation of both. This highlights an important mechanism affecting pathogen
ecology. A paper describing the work is currently under submission.
Figure: Competition between the two pathogens as described in the study. On
the left: schematic representation of the model. At the global scale the two pathogens
(strains) spread among subpopulations, carried by traveling hosts. At the local scales
they infect the hosts within each subpopulations and compete through full crossimmunity. The two pathogens are characterized by two different infection dynamics (a
slower dynamics and a faster one). On the right: model results. Fraction of
subpopulations infected by each strain as a function of hosts’ migration probability,
which provides a measure of the outcome of the competition. According to the
probability value, either the fast or the slow strain dominates over the other, reaching
the majority of the subpopulations.

Enhancing environmental awareness through social information technologies
!
There is now overwhelming evidence that the current organization of our economies
and societies is seriously damaging biological ecosystems and human living conditions
in the very short term, with potentially catastrophic effects in the long term. The
enforcement of novel policies may be triggered by a grassroot approach, with a key
contribution from information and communication technologies (ICT). Nowadays lowcost sensing technologies allow the citizens to directly assess the state of the
environment; social networking tools allow effective data and opinion collection and
real-time information spreading processes. In addition, theoretical and modeling tools
developed by physicists, computer scientists and sociologists have reached the
maturity to analyze, interpret and visualize complex data sets. The EveryAware
project [1] is integrating all crucial phases (environmental monitoring, awareness
enhancement, behavioral change) in the management of the environment in a unified
framework, by creating a new technological platform (Fig. 1) combining sensing
technologies, networking applications and data-processing tools; the Internet and the
existing mobile communication networks are providing the infrastructure hosting such
a platform, allowing its replication in different times and places.
Two main implementations of the EveryAware infrastructure are a case study on
Noise pollution and one on Air-quality. Both of them are accessible here [2]. The
Air-quality case study is based on three main components (see Fig. 1): a SensorBox,
a smartphone with the free app AirProbe and a dedicated Web server and related Web
applications. The SensorBox is a portable device that measures concentrations of
pollutants in the air and localize them through a GPS. The main challenge of our
SensorBox is whether the coupling of several different low-cost sensors helps in
reducing disturbances and provide with a sufficiently accurate measurements. The
SensorBox communicates in real time with a smartphone using a bluetooth
connection. The smartphone is endowed with the free app AirProbe that allows to
monitor in real time the geolocalized levels of pollutants (see Fig. 2). Through the
Internet connection, Air-Probe sends all the measurements to the EveryAware server
that collects in real time data from all users. Through the dedicated Web Applications
users can access the ensemble of the data gathered by the community of users along
as personalized information concerning personal levels of exposure to pollutants. An
intense data analysis and modeling activity parallel the participatory sensing to
investigate the processes through which the exposure to geo-localized and
personalized information triggers a behavioral shift at the individual and collective
levels.

On the origin of complex language patterns
!
!!!!!!
!!!!!!!!!!!!!!!!!
FIG. 1: (Left) The Just Noticeable Difference (JND) is expressing the resolution
power of human eyes. Larger is JND rougher is our discrimination of the
corresponding wavelength (roughly speaking the color), i.e. the wavelength change in
a monochromatic stimulus needed to elicit a particular JND in the hue space. The blue
circles represent the locations of the seven colors for which we monitored the time to
reach consensus in the population. (Right) Time needed to reach consensus versus
the value of Just Noticeable Difference, (here named dmin,) for different regions of the
color space corresponding to the colors reported in the legend (the approximate
wavelength (nm) associated with each colored data point is within parenthesis). Time
is measured as number of games per agent (N is the population size).
On the origin of the hierarchy of color names. One of the fundamental problems in
cognitive science is how humans categorize the visible color spectrum. The empirical
evidence of the existence of universal or recurrent patterns in color naming across
cultures is paralleled by the observation that color names begin to be used by
individual cultures in a relatively fixed order. The origin of this hierarchy is largely
unexplained. In a recent paper published on PNAS [1] we simulated that a population
of individuals, subject to a simple perceptual constraint shared by all humans, namely
the human Just Noticeable Difference, categorizes and names colors through a purely
cultural negotiation in the form of language games. We found that if one ranks
different regions of the visible spectrum according to the time needed for a population
to reach consensus on a color name for each specific region, color spectrum regions
get organized into a hierarchy with [red, (magenta) red], [violet], [green/yellow],
[blue], [orange] and [cyan] appearing in this order (see Fig. 1). The hierarchy
observed in our modeling scheme features an excellent quantitative agreement with
the empirical observations of the World Color Survey. Our results demonstrate a clear
possible route to the emergence of hierarchical color categories, confirming that the
theoretical modeling in this area has now attained the required maturity to make
significant contributions to the ongoing debates concerning language universals.
On the origin of syntactic structures: The lexicons of human languages organize their
units at two distinct levels. At a first combinatorial level, meaningless forms (typically
referred to as phonemes) are combined into meaningful units (typically referred to as
morphemes). Thanks to this, many morphemes can be obtained by relatively simple
combinations of a small number of phonemes. At a second compositional level of the
lexicon, morphemes are composed into larger lexical units, the meaning of which is
related to the individual meanings of the composing morphemes. This duality of
patterning is not a necessity for lexicons and the question remains wide open
regarding how a population of individuals is able to bootstrap such a structure and the
evolutionary advantages of its emergence. In a recent paper published in PLoS ONE
[2] we addressed this question in the framework of a multi-agents model, where a
!
24!
population of individuals plays simple naming games in a conceptual environment
modeled as a graph. We demonstrate that errors in communication as well as a
blending repair strategy, which crucially exploits a shared conceptual representation
of the environment, are sufficient conditions for the emergence of duality of
patterning, which can thus be explained in a pure cultural way. Compositional lexicons
turn out to be faster to lead to successful communication than purely combinatorial
lexicons, suggesting that meaning played a crucial role in the evolution of language.

Complexity of deformation: from micromechanics to earthquakes
!
In a recent work published on the cover of Nature [1]
we have analyzed the deformation of metallic
micropillars under compression. We have formulated a
theory that explained the deformation of these very
small object, whose size is smaller than a hundredth of a
millimiter, and we discovered a general mechanism that
could also be useful to understand the deformation of
the earth crust. It is a clear demonstration of the
principles of complexity according to which the emergent
behavior of a complex system often does not depend on
the details of its constituents but only on the nature of
their interactions.
Understanding the deformation properties of microobjects is a fundamental problem of science and
engineering due to the growing miniaturization of
components and devices. Metals usually deform
plastically and is therefore possible to change their shape with obvious practical
advantages. If, however, the object is very small this formability is lost: the object
will deform in an irregular and incontrolable way with deformation jumps that are
sometimes big and sometimes small. This is a serious problem since standard
engineering models based on continuous theories are not able to account for strong
spatio-temporal heterogeneities as the ones we observe. For this reason we need
completely different modes, as those developed in the field of statistical physics of
complex and disordered systems.
The experiments analyzed here showed intriguing results: when the compression rate
was reduced the micro-avalanche sequence crossed over from a random intermittent
signal to a quasi-periodic behavior, with large events appearing regularly. Crystal
plasticity is due to the motion of defects, dislocations, that move impulsively in
response to the applied stress. In addition to this avalanche motion, dislocations can
also move slowly from one lattice plane to the other with a background motion that is
difficult to observe. We have theoretically shown that when this motion occur at a
speed comparable with the one imposed by the external compression, intermittent
avalanches give way to quasi-periodic events as observed experimentally. The theory
has been demonstrated for micro-plasticity but the mechanism is more general and
could be applied to any mechanical system where two competing relaxation
mechanisms coexist. For instance, in a fault mechanical energy is often relieved
through water flow between earthquakes. If the flow velocity is comparable to the
motion of fault, our theory would suggest the occurrence of quasi-periodic
earthquakes. To confirm the validity of this hypothesis it would be necessary to
analyze a large quantity of experimental data. Understanding how mechanical
response depends on the size, from atomic to macroscopic scales, is the aim of the
SIZEFFECT project funded by the European Research Council and coordinated by

Mathematics of Complexity
The statistical mechanical approach to complex networks is the dominant paradigm in
describing natural and societal complex systems. The study of network properties,
and their implications on dynamical processes mostly focus on locally defined
quantities of nodes and edges, such as node degrees, edge weights and –more
recently– correlations between neighbouring nodes. However, statistical methods
become cumbersome when dealing with many-body properties and do not capture the
precise mesoscopic structure of complex networks.
Moreover, real-world networks usually display intricate patterns of redundant links
with edge weights and node degrees usually ranging over various orders of
magnitudes, which makes it very hard to extract the significant network structure
from the background.
To attack this problem, we designed a scheme to calculate the persistent homological
features of complex weighted networks, with no need to impose an ad-hoc metrical
structure. Indeed, it is possible to define a filtration which effectively returns the
topological strata of the link-weight organization of a given network.
We applied these techniques to a set of real-world networks, highlighting the presence
of two classes distinguished by their homology. In particular, the properties of such
mesoscopic structures divide weighted networks in two broad classes: one
characterised by small hierarchically nested holes, while the second displays larger
and longer living inhomogeneities. These classes cannot be reduced to known local or
quasi-local network properties, and thus yield a new classification built on high order
coordination patterns.
Moreover, preliminary results showed that this technique allows to distinguish the
brain activity (in fMRI data provided by King’s College, London) of patients who
assumed hallucinogenic drugs from those who received placebo.
Our results show that topology can provide novel insight relevant for many-body
interactions in social and spatial networks, while this new method creates the first
bridge between network theory and algebraic topology, which we anticipate will allow
us to import the full toolset of algebraic methods in complex systems science.

rank filtration proceeds from bottom up. Weighted holes (colored) and cliques (gray)

by 3-cliques. The cartoon shows two very long-persistence holes (violet and purple)
appearing quite early and living until the end, while the largest hole (red) branches
into three smaller holes, only one of which survives to the end of the filtration
(green). (b) A selection of weighted holes from the US air passenger network (year
2000). The node colors represent the best modularity partition of the entire network.
The cycles are all long-persistence one, chosen to represent different behaviors: for
example, the Chicago - Los Angeles - San Jose - Seattle cycle spans a large spatial
distance, implying weaker connectivity across the cycle and within the region
encompassed by the cycle, whereas the cycle going east from New York connects the
east coast to three large European networks and its persistence is due to the reduced
connectivity due to the Atlantic Ocean. (c) A selection of the strongest cycles in the
face-to-face contact network in a primary school (see SI for details on dataset). Node
colors represent different classes in the school. Cycles are often found across
communities, since by definition they probe the presence of holes among network
regions. However, this is not the only information they convey. The cycles contained
in a single community (green) testify the presence of peculiar contact geometries
even within dense community structures.

QUANTUM SCIENCE LABORATORY
The activity of the Quantum Physics group at ISI is articulated along two main
directions, deeply connected – even though apparently scarcely related: i) Quantum
Complex Networks; ii) Quantum Life.
i) Quantum Complex Networks theory aims to create a stage for the application of
modern complex network theory to quantum systems, thus establishing on the one
hand a bridge binding the two disciplines, on the other opening the door to the use of
quantum mechanical tools (including quantum information and quantum computation)
to investigate complex networks. The latter are indeed typically faced with questions
that find a natural formulation in terms of coexistent states, multidimensional
correlation matrices, multi-scale interactions, that belong to the toolkit of quantum
mechanics. Also subtler quantum concepts, such as transport properties, entropy
measures, geometry-related correlations and degree distribution of tensor network
states are found to play a deep role in network theory. What is at stake is much more
than simply a framework for novel numerical algorithms: it is the exploration of why
and how, when dealing with complex systems, well established techniques designed to
handle complexity across two rapidly evolving yet so far extraneous areas of science –
network theory and quantum information theory – merge into a universal, unified
conceptual scheme. This feature is even more striking when the mathematical
language of category theory is used to confront the two fields. What the Quantum
Networks ISI researchers involved are active on is the idea that quantum information
would carry new strength and more powerful methods into network science, while
network theory would extend the range of predictability in quantum physics,
circumventing questions until now essentially intractable.
ii) Leading idea of the Quantum Life program is that what differentiates living matter
from inert matter is the feature that in living matter a molecule behaves as a
message, and not so because of any particular shape or structural behavior, but only
in the context of a wider system of physical constraints that can be though of as a
"language". Understanding life requires a higher level than that of conventional
quantum physics: not molecular structures only, but the structure of the language
they mutually communicate with is what is interesting. A reliable theoretical
representation of the origin of the hierarchical organization of living matter and of how
the constraints giving rise to such structured language can actually originate from the
normal physical laws that hold molecules together and govern their motion, is the
'complexity science' issue of the problem, that bridges it with point i). The Quantum
Life group at ISI aims to try and comprehend clearly which are the physical reasons
why living matter is so manifestly different from lifeless matter, in spite of the
evidence that both obey the same set of physical laws. The nature of life is
unavoidably dependent on the writing and reading of records at the single molecule
level and on the sharp distinction between the genetic description and the phenotypic
construction processes. Living matter is distinguished from non-living matter by its
collective behavior in the course of time. On the other hand, there is a by now
undeniable evidence of the presence of relevant quantum effects in biology. One of
the issues regards the transfer of excitations from the acceptor to the reaction center
in antenna, light harvesting complexes related to photosynthesis in plants and
bacteria: light captured by the acceptor creates a 'particle-hole exciton pair' which is
transported to the reaction center (where ultimately the chemical reactions sustaining
life take place) in such efficient way as to apparently defy the laws of
thermodynamics. Such efficiency in energy transfer of the chromoforic complexes is
attributable to a subtle interplay, studied by the ISI Quantum Life group, between
quantum dissipation and dephasing.

Highlights
Tensor Network States: modeling quantum physics to brain function
We all suspect there to be a good deal of commonality in problems faced in different
research fields. Typically this commonality is only noticed long after similar ideas
have both been invented and applied separately. How might we break down those
language barriers to allow working researchers, currently developing new fields, to
bind potentially useful techniques across several disciplines? Although this is not why
tensor networks were invented, perhaps this will be one of their ultimate future
applications.
Tensor networks were invented independently several times. They were not always
invented in precisely the same way each time, and in fact, commonality emerged
between several seemingly distinct areas of science. This commonality allowed
mathematical physicists, particularly through the n-categorical approach, to pinpoint
differences and commonality between different scenarios. At this level of abstraction,
the applications of tensor networks among the sciences appears to either already be
unified (from our work describing everything from digital circuits, analog circuits,
population biology and particularly quantum physics) or to be possible to unify within
the existing framework.
What's more is that tensor networks not only provide a
modeling language, but a precise diagrammatic calculus that can replace reasoning
using equations by calculations done by manipulating diagrams---it's all totally formal.
Measurement of a quantum state defines a monoid structure on tensors.
Our work has aimed at using tensor networks to bind disciplines and in applications to
quantum theory and in contraction algorithms to solve problem instances numerically.
In particular, we have lead the development of these ideas on many fronts.
Everything from connecting tensor network states for quantum theory with algebraic
invariant theory which lead to a diagrammatic interpretation of the equations
representing invariants, to introducing new tensor contraction algorithms to solve the
satisfiability problem. All the while, we have focused on the ideas appearing in
mathematics, to tailor a theory of tensor networks that would aid in reasoning in the
specific problems we faced in our physics research.
The main present application of tensor networks that has gained the most interest is
in their use as a language to model computer algorithms developed to simulate
quantum systems.
By transforming a complex equation into a diagram, tensor
networks often allow one to compress information and the topological structure of the
networks can often reflect mathematical properties of the equations describing the
situation at hand. This structure can help computers solve problems more effectively.

The differences between systems describing tensor networks is often a matter of
syntax versus semantics. For example, typically the rules of how the building blocks
comprising a network interact changes from one scenario to another (e.g. tensor
networks representing classical circuits and tensor networks representing quantum
circuits). However, when restricting the types of allowed tensors, sometimes the
interaction rules don't change across scenarios: in such situations it becomes a matter
of interpretation what the differences are, hence semantics. This opens up an avenue
to explore commonality between seemingly distinct disciplines.
Recently tensor networks have received perhaps the most notable attention in
quantum physics. On the horizon is the applications of tensor network techniques,
particularly tensor network algorithms, to simulate quantum systems, to help revive
an old theory of brain function which uses tensor networks at its core.

Energy transfer in multichromophoric networks
Although research on energy transfer in photosynthesis has a very long history, the
refinement of experimental techniques in the last decade has dramatically enlarged
the range of possible observations at the molecular level, thus boosting new interest
in the field. Recent progress in this context includes new experimental results aimed
at characterizing on the one hand the structure of light harvesting systems in
biological organisms (Fig. 1) and on the other hand the presence and relevance of
quantum effects in the energy transport process. These results are of fundamental
interest since they allow us to shed light onto the mechanisms at the basis of energy
transfer processes, that owing to the long course of natural selection are likely to be
optimally efficient. For this reason a more complete understanding of their features
has also a potential technological impact in providing useful benchmarks on how to
engineer artificial light-harvesting systems.
Energy transport in biological systems takes place in large photosynthetic
chromophore-protein complexes (Fig. 1). In order to describe excitation energy
transfer among different domains one can resort to the description of the detailed
dynamics by means of quantum master equations, an option that requires extensive
numerical calculations, in particular when the photosynthetic complexes to be
simulated are large. However, it turns out that in most complexes not all
chromophores are strongly coupled, and thus the situation is well described by
formation of delocalized states in certain domains (subunits) of strongly coupled
chromophores. In this case one can applied simplified techniques such as the
Multichromophoric Förster Theory (MCFT). The latter represents a simplified but
effective theory for the description of energy transfer processes taking place in large
photosynthetic natural and artificial complexes, where the computational efforts
required by the full quantum simulations may be prohibitive.
However, despite its advantages the multichromophoric Förster theory has been
applied in its full generality only in very few cases, and one usually resorts to its
simplified versions. One of the difficulty that has limited the use of the
multichromophoric Förster theory lies in the lack of relevant theoretical tools for
evaluating emission lineshapes of molecular aggregates, which serve as basis for the
theory. Furthermore a general discussion of its limits of validity is still missing, and
this is mainly due to the impossibility of casting the approach in a sufficiently clear
and concise framework.
It turns out that these problems can be solved. Indeed, on the one hand, with the
help of analytic continuation and time convolutionless quantum master equation
approach, it is possible to devise a scheme for efficiently evaluating the emission
lineshapes. On the other hand, it is possible to provide a general framework in which
the different levels of description of the electronic and bath degrees of freedom are
clearly separated and the different approximations involved can be clearly discussed.
Indeed, one can immediately identify, on the basis of the electronic properties of the
subunits and of the typical bath timescales, if and which genuine multichromophoric
contributions are relevant and must be taken into account, and derive simplified
versions of the multichromophoric transfer rates that encompass the generalized
Förster theories used in the literature. The application of the new theory to simple
paradigmatic systems shows how the multichromophoric approach can give significant
improvements in the determination of energy transfer rates in particular when the
systems under study are not in the purely Förster regime (Fig. 2).

full Multichromophoric approach developed (MC-TCL2) correctly reproduces the exact
rates for a wide range of the relevant noise parameter (lambda). If a simplified theory
is used instead the relative errors (inset) in determining the rates can be very high
(more that 60%).

Information processing with quantum fluctuations
!
One of the most exciting, recent experiments in quantum
information science is the realization of quantum memory. In
a number of experiments the group of E. Poklzik
(Copenhagen) has shown that the state of a laser field can
be stored in collective degrees of freedom of an ensemble of
about 10²³ earth-alcaline atoms at room temperature. When
the light is released after a few microseconds it is in a state
which has a very good fidelity with respect to the original
state.
From a theoretical point of view the basic idea behind
quantum memory is that the quantum fluctuations of an
ensemble of d-level atoms behaves in the large particle limit
like a continuous quantum system. Within the COQUIT
project we have extended the existing theory for this
approach significantly by using mean-field methods and the
Quantum memory:
corresponding results have crucial and far-reaching
Storing one photon in an
implications also on the experimental side, including in
atomic ensemble
particular:
• New methods to deal with ensembles which are far away from the fully polarized
case. One possible area of applications are strategies against noise and decoherence
effects.
• Our scheme is easily generalizable to higher dimensions (i.e. d-level atoms with
d>2). In this context we can provide methods to store d(d-1)/2 modes (rather than
the previously known number d-1) of light into one ensemble if a particular type of
noise is taken into account.
• Our model shows that in the limit of large particle numbers certain classical
variables can occur in addition to canonical position and momentum. In the most
simple setup they are constant and play the role of an effective ħ. With more involved
preparations, and if dissipative dynamics can be taken into account these variables
can become time-dependent. This opens the possibility to simulate experimentally
exotic systems with variable (effective) ħ.

Workshop on "Tensor Network States and Algebraic Geometry"
November 8th, 2012
Tutorials program: November 6th - 7th, 2012
Tensor Network States represents a rapidly growing area of theoretical physics, which
seeks, in part, to understand quantum many-body systems, by a merger of computer
science techniques (based in part on novel methods of lossy compression) paired with
physical insight. These techniques have recently started to defy long held intuitions on
the classes of quantum systems which can be simulated efficiently using classical
computer algorithms. The initial success of these ideas have consequently attracted
significant interest, with several subtopics emerging. This culminates in the use of
more sophisticated mathematics to understand and reason about quantum systems in
general and touches upon notions of complex systems and modern network theory.
This workshop aims to explore this overlap and to seed a cross pollination of ideas
from tensor network states and algebraic geometry as well as the modern theory of
complex systems.
Topics of interest include:
• Applications of Penrose's graphical notation as a formal system of equational
reasoning for tensor network states, algebraic geometry and complex systems
• Applications of the paradigm of modern network theory in algebraic statistics and
tensor network states (and conversely)
• Chirality and time-symmetry breaking in quantum and classical network
transport, quantum walks and Markovian process such as the spread of infectious
disease
• Applications of tensor contraction algorithms appearing in algebraic geometry to
problems faced in quantum physics, and machine learning (and conversely)
• Invariant theory for tensor network states

EE² - Epiwork/Epifor 2nd International Workshop
Facing the Challenge of Infectious Diseases
January 18th - 20th, 2012
Epidemic models aided by computer simulations and information technologies
represent an increasingly important tool for the understanding of transmission
dynamics, and the analysis of epidemic patterns. Thanks to high performance
computing and the innovative use of Information and Communication Technologies
(ICT), sophisticated modeling approaches informed by realistic and detailed data sets
are now feasible and aim at helping and supporting the decision process at the
medical and public health levels. An example is provided by the unprecedented effort
in the use of mathematical and computational models aimed at predicting a variety of
possible scenarios and evaluating treatment and control strategies in real time for the
2009 H1N1 influenza pandemic. While opening new opportunities in the analysis of
infectious diseases, the nascent field of computational epidemiology also faces a
number of technical and conceptual challenges and the uses and quality criteria are
still contrasted especially in the applications to the public health decision making
process.
The Workshop brings together experts in the field of infectious disease modeling to
discuss the advances reached in the use of sophisticate modeling, computational
approaches, and ICT applications in the area of infectious diseases. A special focus will
be on methods for generating rapid parameter estimates, real time forecasting and
the interface between policy making and modeling. A key aim of the workshop is also
the discussion of the research priorities for the future of computational modeling and
ICT applications in the analysis of infectious disease spreading.
The key topics of the meeting are:
• Large Scale Stochastic Simulations
• Networks
• The Impact of Population Structure on Transmission
• Surveillance and policy making
• Evolution and Epidemiology

Assyst Workshop
Mathematics in Network Science: Implications to Socially Coupled Systems
November 21st - 23rd, 2011
Torino, Italy
The revolution in social systems science occurs during interdependent crisis worldwide
in governmental, economic and commercial institutions and the social systems they
embody and serve.
Addressing this situation becomes evermore urgent as, for example, the population of
cities in 40 years time will equal the current global population and most of that growth
will appear in developing nations; all of this occurring in a period of austerity and
retrenchment in the developed world. Global urbanization and sustainable resilient
societies are then obvious grand challenge problems for modern science generally and
network sciences in particular.
Scope of the workshop is to share new ideas about computing, mathematics and
decision-making in a time of increasing interdependency among networks of social,
economic, natural and engineered systems.
The workshop will provide a venue for a range of researchers involved in Network
Science and the emerging applications in two broad themes:
• Network Science as an integrating framework for real world complexity
• Complexity Science in service of governance and policy tools for human survival
in the 21 Century

Dynamics on and of Complex Networks V
University of Vienna, Austria
"Network Science" has recently attracted the attention of a large number of
researchers from across various disciplines, mainly due to its ubiquitous applicability
in modeling the structure and dynamics of large-scale complex systems (both natural
and man-made). Examples of such systems, exhibiting complex interaction patterns
among their constituent entities, range from genetic pathways and ecological
networks to the WWW, peer-to-peer networks, and blogs and online web-social
networks (such as Facebook, Orkut and Twitter).
For the past three years, the primary aim of the series of workshops "Dynamics on
and of Complex Networks", held as a satellite meeting of the European Conference on
Complex Systems, has been to explore the (statistical) dynamics on and of such
complex networks. Dynamics on networks refers to the different types of so called
processes (e.g. proliferation, diffusion etc.) that take place on networks. The
functionality/efficiency of such processes is strongly affected by the topology as well
as the dynamic behavior of the network. On the other hand, Dynamics of networks
mainly refers to various phenomena (for instance self-organization, evolutionary
clustering) that go on in order to bring about certain changes in the topology of the
network.
It has become clear from the past series of workshops "Dynamics on and of Complex
Networks" that modeling social and information dynamics through networks have
gained enormous importance. Consequently, this year the workshop will focus on this
particular theme, i.e., "modeling social and information dynamics through methods of
complex networks".
Some of the topics covered within the umbrella of social dynamics are:
1. Analysis of social network communities: identification of evolutionary communities
2. Temporal analysis of social networks
3. Social media analysis: blogs and friendship networks
4. Privacy in online social networks
5. Trust system over online social networks
6. Search strategies in online social networks
7. Viral propagation in online social networks
!
98!
8. Mobile social networks
Topics under information dynamics include but are not limited to:
1. Peer-to-peer networks: stability, search trust, security and deployment
2. Traffic modeling in information and transportation networks
3. Network based techniques for information retrieval
4. Network analysis of mobile phone data
5. Network science for design and development of wireless/sensor networks
6. Dynamical properties of ad-hoc networks of mobile agents
A closer inspection would make it clear that the issues and the related problems in
this area are still very loosely defined. The primary objective of this interdisciplinary
workshop would be to tie these loose ends and concretize the problems that need to
be urgently addressed through intensive discussions among the expert scientists in
this area.

Lagrange Prize - CRT Foundation Awarding Ceremony
June 30th, 2011
Teatro Vittoria, Italy
The Lagrange Prize-CRT Foundation Edition 2011 has been assigned to Prof. AlbertLászló Barabási.
The Hungarian physicist (of Rumanian origins and US citizen) is the director of the
Center for Complex Network Research at Boston Northeastern University and author
of some among the most brilliant essays and most innovative studies in the field of
complex systems science
Born on March 30th 1967 in the small village of Cârţa, along the eastern borders of
Transilvania, Barabàsi was an enfant prodige of international research in the 90’s,
when, at the age of 32, he was named the Emil T. Hofman Professor of Physics at the
University of Notre Dame, in Indiana. In 2007 he moved to the Northeastern
University, where he is now Director of the Center for Network Science. He
collaborates with the Department of Medicine of the Harvard Medical School and is
member of the Center of Cancer Systems Biology at the Dana Farber Cancer Institute.
Renowned for his innovative and transversal approach, in which physics combines
freely with other sectors of scientific and humanities research – from molecular
biology to computer science, to human behaviour - Barabàsi has repeatedly surprised
the academic world with his studies. Starting from his first research in 1999 on the
World Wide Web, which led him to conclude that the Internet was not a “casually
linked” network and hence formulating the theory of scale-free network, till to his
recent studies on human mobility and the possibility to forecast routes and shifts
thanks to traces left by mobile phones and other technological devices. He has been
awarded with numerous prizes, often related to different disciplines: from the FEBS
Anniversary Prize for Systems Biology, awarded in 2005 by the Federation of
European Biochemical Societies (Barabàsi has discovered that scale-free networks
apply also to metabolic and cellular systems), to the NEC Computers and
Communication Award of 2008, for the achievements made in computer and IT
science.
Beyond his research activity, Barabàsi is also a science divulger, both via papers
published on specialized reviews and books. Two of his essays – both translated into
Italian by Einaudi – are considered among the key texts in the analysis of complex
networks in modern optics. In “Linked. The Network Science (2004)”, he has shared
with the general public the most recent theories and the principles of the study of
network systems; in his most recent book, “Bursts: The Hidden Pattern Behind
Everything We Do (2011)”, he has instead suggested a revolutionary theory according
to which – thanks to the entrance of the world into the age of complex networks – not
only natural phenomena but also the behaviours of human beings can be traced and
predicted: they do not develop regularly but concentrating in true bursts of
hyperactivity.
!

“With his revolutionary research, highlighting the deepest motivations at the basis of
common organizational principles and of complex network characteristics” – so quotes
the motivation of the Lagrange Prize – CRT Foundation, “Albert László Barabàsi has
provided those fundamental concepts necessary to understand the network structures
observed in a wide spectrum of models and dominions, ranging from information
systems to the microscopic world of molecular biology, so opening new areas for the
application of complex systems science”.
The prize awarding ceremony has been inaugurated by the address given by Giovanni
Ferrero (CRT Foundation) and Ralph Dum (EU Future Emerging Technologies), and
has been developped as a conversation between Barabàsi and Alessandro Vespignani,
ISI Scientific Director – Institute for Scientific Interchange of Torino – and of the
Research Center for Complex Networks and Systems of Indiana University, USA. The
meeting has been coordinated by Vittorio Bo, founder of the publishing house Codice
Edizioni and director of Genoa Science Festival. The remarks by Angelo Miglietta (CRT
Foundation) and Mario Rasetti (ISI Foundation) closed the ceremony.
On the same day, in the morning, at 11:00 am, Albert László Barabàsi will participate in a
press conference organized at the main site of CRT Foundation, in via XX Settembre 31,
Torino.
The Lagrange Prize – CRT Foundation, entitled to the scientist and mathematician
Joseph-Louis Lagrange, was established in Torino, in 2007, upon an initiative by
Fondazione Cassa di Risparmio of Torino and under the coordination of ISI Foundation
– Institute for Scientific Interchange; the prize is the most important International
award for the study of complex systems (a sector in which Torino has been playing a
leading role for years and at world level). In the past editions, the Prize – consisting in
a research grant of fifty-thousand Euros – was awarded to the Russian mathematician
Yakov Grigorievich Sinai, the British economist William Brian Arthur (2008), the
Italian physicist Giorgio Parisi (2009) and the US bioengineer James J. Collins (2010).
Incontro Nazionale FuturICT Italia
June 13th, 2011
Centro Congressi Torino Incontra, Italy
All’interno del programma Europeo Future and Emerging Technologies è stata lanciata
l’iniziativa Flagship, che finanzia progetti di ricerca “visionari” di grandi dimensioni e
caratterizzati da una forte interdisciplinarietà.
In questo ambito il progetto “FuturICT” (si veda il flyer all'indirizzo:
http://www.futurict.ethz.ch/data/flyer/FuturICT-Flyer-to-view.pdf ) rappresenta una
delle Coordination Action che costituisce il primo passo di un iter strutturato in due
fasi che ha come scopo ultimo quello di ottenere il finanziamento di un progetto
decennale.
Il progetto FuturICT si propone di integrare l'uso delle ICT, le scienze della
complessità e le scienze sociali per produrre un cambio di paradigma nello studio dei
fenomeni sociali e per rendere più consapevole, efficace e scientificamente fondata la
gestione delle sfide planetarie del futuro (dalle crisi finanziare globali sino ai disastri
ambientali). Scopo della Coordination Action è non solo quello di preparare la
proposta Flagship FET per la seconda fase, ossia per il progetto decennale, ma anche
quello di costruire una rete di comunità scientifiche nazionali in grado di implementare
il progetto. Nel caso dell’Italia, e’ stato chiesto ai core partners della coordination
action di formare un gruppo di coordinamento (http://www.futurict.it/) con il compito
di organizzare e coordinare la comunita’ nazionale interessata al progetto. All scopo
di avere un momento di incontro della nascente comunità nazionale, si e’ organizzato
per il 13 giugno 2011 un incontro preliminare rivolto a tutti i gruppi scientifici e i
!

ricercatori interessati nell’iniziativa. Nell’ambito della giornata d’incontro è stata
illustrata l’iniziativa FuturICT e i primi passi intrapresi dalla coordination action. Inoltre
è stato dato ampio spazio per una discussione e presentazione delle attivita’ di ricerca
nazionali che permettano di identificare strutture e competenze rilevanti ai fini del
progetto.

Epiwork Science Board Meeting
December 6th - 7th, 2010
This second project meeting is intended not only as a check point of the activities of
the project within the consortium but also, more importantly, as a moment for
establishing the future integration and joint research among the partners and among
the Work Packages.
The meeting allows, as the previous years, all partners to provide a summary of the
activities undertaken and the progress of the research activities. Nevertheless, the
agenda allows large room for the discussion about the future direction of the research
activities for the next years from the integration and interdependence point of view.
As the first year, we also have all the formal moment of the consortium with the
Steering committee meeting. Emphasis should be given to the discussion of the
previous year feedback concerning integration, collaborations and exploitation of the
results.

ASSYST - Action for the Science Of Complex Systems and Socially Intelligent
ICT
ASSYST will coordinate research around the call Science of complex systems for
socially intelligent ICT (COSI-ICT) in the context of the wider science of complex
systems (CS).
ASSYST will make Complex Systems science and the potential of COSI-ICT better
understood by scientific policy makers and funders at national and international levels
in Europe. It will show case successful applications of the science. It will inform
European policy makers on the global context of European CS and COSI-ICT and
funding policies. It will advice policy makers and scientists on the state of the art, and
provide high quality input and advice for funding policies at national level and for the
funding agencies of the European Commission including FP7.
ASSYST will promote applications of complex systems and COSI-ICT in the public and
private sectors, and publicize successful applications. It will build bridges between
complex systems scientists and industry and commerce in Europe and actively
promote civil and commercial applications of the new ICT-driven science.
ASSYST will achieve its mission through organizing many meetings across Europe and
around the world with targeted outcomes related to its objectives through proactive
engagement with policymakers, the business community, an the public sector. It will
provide open educational resources to promote complex systems science and COSIICT. It will provide conference support for rapid dissemination of complex systems
and COSI-ICT research. It will collect information and publish it in easily accessible
forms available through an excellent “one stop” CS and COSI-ICT web site.

Bovine Livestock Mobility
Livestock movements represent the main mean of propagation of zoonotic infectious
diseases. The analysis of the dynamical pattern of the cattle trade movements, along
with the numerical simulations of diseases spreading is the crucial ingredient to devise

efficient preventive and control strategies against epidemic outbreaks. By integrating
detailed data of bovines’ displacements and leveraging on the network science
approach, this project aims at developing a computational framework to study real
epidemic outbreaks.

COQUIT - Collective quantum operations for information technologies
The purpose of this project is to study quantum systems which allow only a partial
control by a constrained set of quantum operations. Typical examples are many
particle quantum systems like cold atoms in optical lattices or other multi-atom
ensembles, which can be manipulated collectively but not individually (e.g. because
the spatial resolution of the used devices is not good enough to address single
particles). Such restrictions are currently one of the biggest obstacles against working
quantum computers. Instead of improving the corresponding experimental methods
(i.e. searching for better implementations) this project aims at a systematic study of
the tasks which can be performed with currently available techniques. To this end we
want to develop theoretical models which can on the one hand reflect the limitations
of current experimental setups, but are on the other hand powerful enough to allow
non-trivial practical applications. This point of view is new and complementary to most
other research in quantum information science, where complete control over a small
number of particles is assumed. Based on these models we plan in a second step to
produce strategies for the generation of devices which are - at least for a very special
task - more powerful than classical computers, and at the same time easily
implementable. Possible applications of this procedure are simulations of other
quantum systems, like models for ferromagnetic materials with long range quantum
correlations or lattice approximations of quantum field theories, which can not be
treated efficiently on classical computers (i.e. the computation time grows
exponentially with the system size). The advantage of our approach over other
research which directly tries to implement universal quantum computers is a much
greater success probability (at least short- or mid-term).

DYNANETS - Computing Real-World Phenomena with Dynamically Changing
Complex Networks
Recent advances in experimental techniques such as detectors, sensors, and scanners
have opened up new windows into physical and biological processes on many levels of
detail. The complete cascade from the individual components to the fully integrated
multi-science systems crosses many orders of magnitude in temporal and spatial
scales. The challenge is to study not only the fundamental processes on all these
separate scales, but also their mutual coupling through the scales in the overall
system, and the resulting emergent properties. These complex systems display
endless signatures of order, disorder, self-organization and self-annihilation.
Understanding, quantifying and handling this information complexity is one of the
biggest scientific challenges of our time. Amazingly nature seems to be able to
process information on many spatial scales simultaneously. DynaNets will study and
develop a new paradigm of computing through Dynamically Changing Complex
Networks reproducing the way nature processes information. It will develop theory
and methods of dynamical networks providing us with new insights into the underlying
processes of nature, economy, and society. As a pilot study we will investigate the
dynamics of the HIV and influenza epidemics from the molecule all the way up to the
population.

decision-makers, and will generate a variety of research and consultancy projects in
Europe and elsewhere.GSDP will operate over a period of three years. In the first
year, researchers and practicioners will meet in workshops and seminars to produce
reports on the state of the art in the relevant fields. They will not only assess the
scientific literature, but also carefully look at how the science-policy interface is
currently defined. At the end of the year, a first annual conference will help to
synthesise the different reports in view of the envisaged research program.In the
second year, analogous reports will be produced about challenges and questions in
research and at the science-policy interface. The first two years will provide answers
to three questions. What do we need? What do we know? What are we struggling
with? In the third year, these answers will be transformed into a research program for
global systems science by first producing a set of components, then combining them
into a coherent picture.The researchers involved come from computer science,
physics, economics and a variety of other fields. GSDP is embedded in an active
network of more than 100 researchers, and in a variety of stakeholder relations with
businesses, political authorities, and NGOs. Many links exist to the U.S., and care has
been taken to establish strong linkages with China. The work will be broken down into
seven work packages that operate in parallel, synchronized by annual conferences and
interacting through meetings, documents, and intensive use of ICT.

Information and Communication Technologies (ICT). The dynamics of building and
strengthening social relationships have evolved through the use of ICT, and new ICTmediated groups and communities have emerged. Individuals, communities, society,
and ICT have become deeply intertwined in a dynamic feedback process. The
fundamental challenge for future social ICT is to overcome the acute lack of
understanding of the driving forces and mechanisms of this complex system of
interactions. The project aims to develop systematic exploration, understanding, and
modelling of systems where ICT is entangled with social structures.
Currently, there is no general understanding, either at the individual or collective
!
111!
level, of how ICT-mediated social interactions and patterns of influence work. In
particular, there is a critical gap in our understanding of how different levels of social
behaviour are related to each other. Moreover, the existing knowledge in this area is
highly fragmented between different scientific disciplines such as social psychology,
computer science, and complexity science. The main theoretical issue of this project is
to help to find out how an ICT-mediated community is born and what kind of driving
forces shape its evolution. The major goal of ICTeCollective is to bridge the above gap
of understanding and solve this issue, by using multi-level and multi-scale approaches
to understand ICT mediated social dynamics at a societal level in relation to microand meso-scale processes. This goal will be achieved by carrying out original
experiments on the impact of ICT on human behaviour, analysing ICTgenerated large,
unique, and time-stamped datasets, constructing and investigating models and
building up a more general theoretical framework. The interdisciplinary approach of
ICTeCollective aims to produce new insight and integrate the fragmented knowledge
of different scientific disciplines concerning social aspects and consequences of ICT
into a coherent form, which is amenable to be used in policy-making decisions and for
the benefit of technology developer in public and industrial sectors.
This coherent form of knowledge is achieved by first zooming in to the various facets
of social ICT:
1) Patterns observed from datasets and data gathered from laboratory experiments
for insight to different roles of different patterns and how do they relate to the
topological position?
2) Hierarchical organization, revealed through multi-scale approach with different WPs
providing different aspects, to build the joint picture via experiments revealing
individual behaviour and group formation and dynamics at micro- and mesoscopic
levels and via community detection and dynamics studies of datasets at mesoscopic
(community) and macroscopic (societal) level (shown e.g. in value production by
individuals contributing and forming communities for the best encyclopaedia).
3) Interplay between ICT and society, in which new devices and services change
individual behaviour/habits, contribute to new ways of community formation and
group dynamics, which, finally, result in a deep change of the whole society, reflected
in the demands awakened by the new technologies. These different facets studied in
the WPs are the building blocks for the big integrated picture of social ICT.
As a final outcome we end up forming an integrated picture and multi-level model, in
other words a theory of ICT-mediated social systems and group formation and
dynamics.
Furthermore, as concrete results we end up having developed generic methodological
approaches and analysis and modelling tools together with novel algorithms and
software, which together with the theory will be disseminated through the web and by
other means for to be applied to other ICT-mediated systems of collective social
behaviour by researcher, policy makers, industry, and general public.

IMPROVING STRATEGIES FOR PREVENTING PERTUSSIS IN INFANTS
The project aims to collect evidence for supporting prevention strategies that could be
integrated into the current pertussis control programs. The project will include three
major components:
1) Enhancement of diagnostic approaches to reveal the unrecognized burden of
pertussis
This component has the aim to recognize undiagnosed cases of pertussis and to study
circulating variants of B. pertussis in children below 6 months of age with symptoms
of a lower respiratory infection. Frequency and severity of coinfection of B. pertussis
with other respiratory pathogens will also be studied. Variants of B. pertussis will be
investigated for antigenic distinction from vaccine strains and increased production of
pertussis toxin together with the antibiotic resistance.
2) Recognition of epidemiological and immunological role of breast feeding in pertussis
prevention
This component of the study will integrate an epidemiological and an immunological
approach to study the role and the mechanism that breast feeding may have in
pertussis prevention. We will compare the risk of acquiring pertussis in breast and
formula fed infants and we will compare maternal and neonatal serum specific
antibody levels, determine the ability of SIgA to opsonize B. pertussis and prevent
adhesion to epithelial cells. The role of bacterial species in pharinx of children with
B.pertussis infection will be studied as well.
3) Determination of pattern of contacts in households of infants with pertussis
We will study the chain of transmission of pertussis in households of infected infants
and the immunological profile of households. A novel approach will be used to
measure the precise pattern of contacts among households of healthy infants to
provide data for feeding mathematical models for transmission.

MULTIPLEX - Foundational Research on MULTIlevel comPLEX networks and
systems
Future advancements in ICT domain are closely linked to the understanding about
how multi-level complex systems function. Indeed, multi-level dependencies may
amplify cascade failures or make more sudden the collapse of the entire
system. Recent large-scale blackouts resulting from cascades in the power-grid
coupled to the control communication system witness this point very clearly. A better
understanding of multi-level systems is essential for future ICT’s and for improving life
quality and security in an increasingly interconnected and interdependent world. In
this respect, complex networks science is particularly suitable for the many challenges
that we face today, from critical infrastructures and communication systems,
totechno-social and socio-economic networks.
!

MULTIPLEX proposes a substantial paradigm shift for the development of a
mathematical, computational and algorithmic framework for multi-level complex
networks. Firstly, this will lead to a significant progress in the understanding and the
prediction of complex multi-level systems. Secondly, it will enable a better control,
and optimization of their dynamics. By combining mathematical analyses, modelling
approaches and the use of massive heterogeneous data sets, we shall address several
prominent aspects of multi-level complex networks, i.e. their topology, dynamical
organization and evolution.

NNOSIP - Neuronal Network Oscillations and Sensory Information Processing
The temporal structure of cortical activity contains robust sensory-evoked oscillations
spanning a wide frequency range. Yet, the role of these oscillations in encoding
sensory information remains largely unknown. We hypothesize that oscillations are
key for transmitting sensory information through cortex, and we aim to discover how
the brain uses oscillations to encode sensory information. We will model the
mechanisms of generation of oscillations using computational models of interacting
local neural populations; compute the information content of these oscillations; and
compare it systematically to real cortical responses (provided by our collaborator
Logothetis).

Q-ARACNE - Quantum Complex Networks
The project is articulated along three main guiding lines, Quantum Bio, Complex
Networks, Mathematics of Complexity, deeply rooted in the tradition of the ISI
Foundation, mutually bridged in a subtle far reaching way: i) the "quantum physics"
group at the ISI Foundation the is presently engaged in developing an extraordinary
tool, quantum complex networks; ii) the latter – not unexpectedly – bear on several
quantum issues of biological systems, but also of social (intelligent) systems where
one of the crucial processes is random walk over discrete structures in the space of
states whose formal properties are those of complex networks. What relates these
two physically unrelated networks is the common description in terms of 'sums over
histories', typical of quantum physics; iii) the new mathematics of complex systems
related to topological features of the space of data glues such apparently distant
applications, quantum biological systems and social systems, in a universal, unified
representation scheme based on topological aspects of both classical and quantum
computation.

SIZEFFECTS - Size Effects in Fracture and Plasticity
Understanding how materials respond to external mechanical perturbation is a central
problem of science and engineering. While for most practical purposes it is useful to
idealize the mechanical response of a material as a deterministic function of the
externally applied perturbation, disorder and fluctuations are unavoidable, leading to
sample-to-sample variations and non-trivial size effects. In the SIZEFFECT project,
concepts and tools of statistical mechanics are used to address size effects and
fluctuations in the irreversible deformation and failure of materials. The general
objective is to provide a quantitative theory that can be used as base for setting
reliable safety factors. The theory will be based on the renormalization group and will
be guided and validated by large scale numerical simulations such as molecular
dynamics, discrete dislocation dynamics and disordered network models. Finally, we
will analyze experimental data present in the literature. SIZEFFECT is supported by EU
as an ERC Advanced Grant and is in collaboration with CNR.

TOPDRIM – Driven Methods for Complex Systems
Many complex systems are characterized by multi-level properties that make the
study of their dynamics and of their emerging phenomena a daunting task. The huge
amount of data available in modern sciences can be expected to support great
progress in these studies, even though the nature of the data varies. Given that, it is
crucial to extract as much as possible features from data, including qualitative
(topological) ones. The goal of this project is to provide methods driven by the
topology of data for describing the dynamics of multi-level complex systems. To this
end the project will develop new mathematical and computational formalisms
accounting for topological effects. To pursue these objectives the project brings
together scientists from many diverse fields including as topology and geometry,
statistical physics and information theory, computer science and biology. The
proposed methods, obtained through concerted efforts, will cover different aspects of
the science of complexity ranging from foundations, to simulations through modelling
and analysis, and are expected to constitute the building blocks for a new generalized
theory of complexity.

LAGRANGE PROJECT
The CRT Foundation, which since always has been supporting qualified research
projects started and developed by the Piedmontese Universities, ranging from Turin
Polytechnic to national and regional institutes, has decided to intervene in a
structured and coordinated way in the research sector by starting the Lagrange
Project. To guarantee the high level of excellence to pursue, the scientific coordination
of such project will be managed by ISI Foundation (Institute for Scientific
Interchange), of which CRT Foundation has been since 1983 among the founding
members. The research sector that will be actively supported is that defined as that of
the Challenge of Complex Systems, which has become nowadays a sort of paradigm
of modernity. And, in this context, Turin and Piedmont have been considered to have
reached national and international excellence levels in sectors such as IT, biology,
quantum physics, neuroscience and economics, which allow - together with other
disciplines - to accept the ambitious challenge of complexity coming form the scientific
community: "complexity" to design, map and develop such interdisciplinary approach
and area.
The choice of entitling the project to Lagrange, the greatest mathematician and
scientist born and lived in Turin and Piedmont, is a precise indication on the work
methodology we want to apply. In fact, Lagrange represents the economics of Nature
and the mystery of our ability to know it. Science has a general principle whose
concept is simple and powerful at the same time showing a sort of absolute paradigm:
the principle of minimum action. This principle has gone unchanged through time and
the extraordinary developments of science, even the most recent ones, which have
influenced so much our way of representing the Nature's laws.
The Lagrange project intends to follow the principle of minimum action while looking
for a multiplying effect of the resources invested by CRT Foundation and at the same
time avoiding useless duplications of already existing projects and organizations.
In this context, Turin and Piedmont have been considered to have achieved national
and international excellence levels in sectors such as IT, biology, quantum physics,
!
118!
neuroscience and economics that allow to take over the ambitious challenge of
complexity coming from the scientific community; "complexity" to design, map and
develop such interdisciplinary territory and environment.
Having "excellence" as goal and tool at the same time, the Lagrange Project, together
with the already existing research facilities, intends to start a new path towards a new
culture of innovation (research and life / research and enterprise) that may also
generate a positive spin-off on the Piedmontese production system.
In this way the challenge of complexity becomes a sort of paradigm of modernity and
wants to find in Turin and Piedmont one of the seats for this fundamental research.
TOOLS
The intervention modalities identified by the Lagrange Project are scholarships and
contracts: they are the classical support tools of research activities to which a new
articulation and results' control system has been given so characterizing them with
significant innovation features.
The assignment of the Lagrange Fellow doctorate, research scholarships and contracts
as well as the invitations for senior fellows will take place in the framework of the
research projects whose guidelines were approved by the scientific committee so
establishing one common link among all four support tools in the most factual way.
The innovative methodology we would like to experiment regards the control phase of
the results achieved by means of theme/special interest workshops open to the whole
scientific "community" of the Lagrange Project and also including external subjects as
well as Piedmontese enterprises.
The intervention tools are:
-
Doctorate Scholarships
Applied Research Scholarships
Lagrange Start up Scholarships
Lagrange Fellow
PUBLISHING ACTIVITIES
One of the main objectives of the Lagrange Project is spreading the culture of
research and technological innovation in a wider way, thus contributing to enhance
the competitive abilities of the Piedmontese system.
In line with that, a specific editorial and publishing activity (volumes of scientific
divulgation and research) has been established and released in collaboration with
partner publishers.
In the period 2010-2011, with the Lagrange Project support these books has been

by means of the propensity score.
Paired and case-crossover studies are introduced on the design control plan, in the
most general case-only family studies.
Explorative analyses and studies based on functional genomic data require the
introduction of False Discovery Rate control techniques and multivariate techniques.
The evaluation of interventions and cluster randomization trials, together with
performance analyses of health structures requiring multilevel statistical models, and
the probability of uncertainty test connected to structure ranking.
