More Is Less: Signal Processing and the Data Deluge, Science
Abstract: The data deluge is changing the operating environment of many sensing systems from data-poor to data-richâ€"â€"so data-rich that we are in jeopardy of being overwhelmed. Managing and exploiting the data deluge require a reinvention of sensor system design and signal processing theory. The potential pay-offs are huge, as the resulting sensor systems will enable radically new information technologies and powerful new tools for scientific discovery.
Happy People Live Longer, Science
Excerpt: There is a longstanding idea that happiness causes people to live longer, healthier lives. However, convincing evidence that subjective well-being (the more scholarly term for happiness) contributes to longevity and health has not been available. Recently, however, social psychologists Diener and Chan showed that many kinds of studies, using different methods, conclude that happiness has a positive causal effect on longevity and physiological health.

Rescuing ecosystems from extinction cascades through compensatory perturbations, Nature Communications
Excerpt: Food-web perturbations stemming from climate change, overexploitation, invasive species and habitat degradation often cause an initial loss of species that results in a cascade of secondary extinctions, posing considerable challenges to ecosystem conservation efforts. Here, we devise a systematic network-based approach to reduce the number of secondary extinctions using a predictive modelling framework. We show that the extinction of one species can often be compensated by the concurrent removal or population suppression of other specific species, a counterintuitive effect not previously tested in complex food webs.
Dispensability of Escherichia coli's latent pathways, PNAS
Excerpt: Gene-knockout experiments on single-cell organisms have established that expression of a substantial fraction of genes is not needed for optimal growth. This problem acquired a new dimension with the recent discovery that environmental and genetic perturbations of the bacterium E. coli are followed by the temporary activation of a large number of latent metabolic pathways, which suggests the hypothesis that temporarily activated reactions impact growth and hence facilitate adaptation in the presence of perturbations. Here, we test this hypothesis computationally and find, surprisingly, that the availability of latent pathways consistently offers no growth advantage and tends, in fact, to inhibit growth after genetic perturbations (...)
Excerpt: [I] argue that complexity science isn't a fad. I will offer a brief survey of some core concepts and ideas, and I will make a strong case that the tools and ideas of complex systems theory can give us significant purchase on the new and strange world we're living in today. Most importantly, they can help us develop new strategies for generating solutions and prospering in this world.
Michael Pawlyn: Using nature's genius in architecture, TED.com
About this talk: How can architects build a new world of sustainable beauty? By learning from nature. At TEDSalon in London, Michael Pawlyn describes three habits of nature that could transform architecture and society: radical resource efficiency, closed loops, and drawing energy from the sun.

Cynthia Breazeal: The rise of personal robots, TED.com
About this talk: As a grad student, Cynthia Breazeal wondered why we were using robots on Mars, but not in our living rooms. The key, she realized: training robots to interact with people. Now she dreams up and builds robots that teach, learn -- and play. Watch for amazing demo footage of a new interactive game for kids.
Thomas Goetz: It's time to redesign medical data, TED.com
About this talk: Your medical chart: it's hard to access, impossible to read -- and full of information that could make you healthier if you just knew how to use it. At TEDMED, Thomas Goetz looks at medical data, making a bold call to redesign it and get more insight from it.
Critical Overview of Agent-Based Models for Economics, arXiv
Abstract: We present an overview of some representative Agent-Based Models in Economics. We discuss why and how agent-based models represent an important step in order to explain the dynamics and the statistical properties of financial markets beyond the Classical Theory of Economics. We perform a schematic analysis of several models with respect to some specific key categories such as agents' strategies, price evolution, number of agents, etc. In the conclusive part of this review we address some open questions and future perspectives and highlight the conceptual importance of some usually neglected topics, such as non-stationarity and the self-organization of financial markets.
A Biological Solution to a Fundamental Distributed Computing Problem, Science
Excerpt: Computational and biological systems are often distributed so that processors (cells) jointly solve a task, without any of them receiving all inputs or observing all outputs. Maximal independent set (MIS) selection is a fundamental distributed computing procedure that seeks to elect a set of local leaders in a network. A variant of this problem is solved during the development of the flyâ€™s nervous system, when sensory organ precursor (SOP) cells are chosen. By studying SOP selection, we derived a fast algorithm for MIS selection (...)
Google matrix of business process management, Eur. Phys. J. B
Abstract: Development of efficient business process models and determination of their characteristic properties are subject of intense interdisciplinary research. Here, we consider a business process model as a directed graph. Its nodes correspond to the units identified by the modeler and the link direction indicates the causal dependencies between units. It is of primary interest to obtain the stationary flow on such a directed graph, which corresponds to the steady-state of a firm during the business process. Following the ideas developed recently for the World Wide Web, we construct the Google matrix for our business process model and analyze its spectral properties. The importance of nodes is characterized by PageRank and recently proposed CheiRank and 2DRank, respectively. The results show that this two-dimensional ranking gives a significant information about the influence and communication properties of business model units. We argue that the Google matrix method, described here, provides a new efficient tool helping companies to make their decisions on how to evolve in the exceedingly dynamic global market.
El Farol revisited: A note on emergence, game theory, and society, Complexity
Abstract: The El Farol paper examined the evolution of behavior of visits to a potentially crowded facility, providing an insightful view of how independent agents can coordinate in a "good enough" manner in many situations. This view is extended to considering the interaction between rules and behavior. The context may be such that the importance of the outcome is sufficiently high to merit an extra layer of complexity in the guidance of the emergent behavior and that behavior may signal the need for the additional complexity.
Schema Redescription in Cellular Automata: Revisiting Emergence in Complex Systems, arXiv
Excerpt: We present a method to eliminate redundancy in the transition tables of Boolean automata: schema redescription with two symbols. One symbol is used to capture redundancy of individual input variables, and another to capture permutability in sets of input variables: fully characterizing the canalization present in Boolean functions. Two-symbol schemata explain aspects of the behaviour of automata networks that the characterization of their emergent patterns does not capture. (...) we demonstrate that it is more feasible to compare cellular automata via schema redescriptions of their rules, than by looking at their emergent behaviour, leading us to question the tendency in complexity research to pay much more attention to emergent patterns than to local interactions.
Detecting evolving patterns of self-organizing networks by flow hierarchy measurement, Complexity
Abstract: Hierarchies occur widely in evolving self-organizing ecological, biological, technological, and social networks, but detecting and comparing hierarchies is difficult. Here we present a metric and technique to quantitatively assess the extent to which self-organizing directed networks exhibit a flow hierarchy. Flow hierarchy is a commonly observed but theoretically overlooked form of hierarchy in networks. We show that the ecological, neurobiological, economic, and information processing networks are generally more hierarchical than their comparable random networks. We further discovered that hierarchy degree has increased over the course of the evolution of Linux kernels. Taken together, our results suggest that hierarchy is a central organizing feature of real-world evolving networks, and the measurement of hierarchy opens the way to understand the structural regimes and evolutionary patterns of self-organizing networks. Our measurement technique makes it possible to objectively compare hierarchies of different networks and of different evolutionary stages of a single network, and compare evolving patterns of different networks. It can be applied to various complex systems, which can be represented as directed networks.
Metabolic Robustness and Network Modularity: A Model Study, PLoS ONE
Excerpt: Several studies have mentioned network modularity -that a network can easily be decomposed into subgraphs that are densely connected within and weakly connected between each other- as a factor affecting metabolic robustness. In this paper we measure the relation between network modularity and several aspects of robustness directly in a model system of metabolism.
Path planning strategies inspired by swarm behaviour of plant root apexes, European Space Agency
Excerpt: Exploring unknown environments and identifying potentially interesting or hazardous areas is a challenging task for an autonomous agent. In the ab- sence of a priori provided maps or landmarks guiding navigation, researchers are considering multi-agent systems trying to exploit the inherent parallelism of such systems. Many scientific research works following this direction draw inspiration from biological swarm models. In such models, self-organised ex- ploration strategies emerge at the collective level as a result of simple rules followed by individual agents.

Excerpt: A finite-population dynamic evolutionary model is presented, which shows that increasing the individual capacity of sending pre-play signals (without any pre-defined meaning), opens a route for cooperation. The population dynamics leads individuals to discriminate between different signals and react accordingly to the signals received. The proportion of time that the population spends in different states can be calculated analytically. We show that increasing the number of different signals benefits cooperative strategies, illustrating how cooperators may take profit from a diverse signaling portfolio to forecast future behaviors and avoid being cheated by defectors.
Evolution of cooperation among mobile agents, Physica A
Excerpt: We study the effects of mobility on the evolution of cooperation among mobile players, which imitate collective motion of biological flocks and interact with neighbors within a prescribed radius R. Adopting the the prisonerâ€™s dilemma game and the snowdrift game as metaphors, we find that cooperation can be maintained and even enhanced for low velocities and small payoff parameters, when compared with the case that all agents do not move. [...] Our findings may help understanding the relations between individual mobility and cooperative behavior in social systems.
Cooperation among non-relatives evolves by state-dependent generalized reciprocity, Proc. R. Soc. B
Excerpt: For decades, attempts to understand cooperation between non-kin have generated substantial theoretical and empirical interest in the evolutionary mechanisms of reciprocal altruism. There is growing evidence that the cognitive limitations of animals can hinder direct and indirect reciprocity because the necessary mental capacity is costly. Here, we show that cooperation can evolve by generalized reciprocity (help anyone, if helped by someone) even in large groups, if individuals base their decision to cooperate on a state variable updated by the outcome of the last interaction with an anonymous partner.
Oscillatory phase coupling coordinates anatomically-dispersed functional cell assemblies, PNAS
Excerpt: Hebb proposed that neuronal cell assemblies are critical for effective perception, cognition, and action. However, evidence for brain mechanisms that coordinate multiple coactive assemblies remains lacking. Neuronal oscillations have been suggested as one possible mechanism for cell assembly coordination. (...) Phase-coupling preferences correlate with behavior and neural function and remain stable over multiple days. These findings suggest that neuronal oscillations enable selective and dynamic control of distributed functional cell assemblies.

Collective Classification of Textual Documents by Guided Self-Organization in T-Cell Cross-Regulation Dynamics, arXiv
Excerpt: We present and study an agent-based model of T-Cell cross-regulation in the adaptive immune system, which we apply to binary classification. Our method expands an existing analytical model of T-cell cross-regulation (Carneiro et al. in Immunol Rev 216(1):48-68, 2007) (...) we show that such self-organizing dynamics can be guided to produce an effective binary classification of antigens, which is competitive with existing machine learning methods when applied to biomedical text classification.
Abstract: A methodology based on embedded pneumatic networks (PneuNets) is described that enables large-amplitude actuations in soft elastomers by pressurizing embedded channels. Examples include a structure that can change its curvature from convex to concave, and devices that act as compliant grippers for handling fragile objects (e.g., a chicken egg).

Fairness Emergence in Reputation Systems, JASSS
Excerpt: Reputation systems have been used to support users in making decisions under uncertainty or risk that is due to the autonomous behavior of others. Research results support the conclusion that reputation systems can protect against exploitation by unfair users, and that they have an impact on the prices and income of users. This observation leads to another question: can reputation systems be used to assure or increase the fairness of resource distribution? This question has a high relevance in social situations where, due to the absence of established authorities or institutions, agents need to rely on mutual trust relations in order to increase fairness of distribution.
Zaller-Deffuant Model of Mass Opinion, JASSS
Abstract: Recent formulation of the Zaller model of mass opinion is generalized to include the interaction between agents. The mechanism of interaction is close to the bounded confidence model. The outcome of the simulation is the probability distribution of opinions on a given issue as dependent on the mental capacity of agents. Former result was that a small capacity leads to a strong belief. Here we show that an intensive interaction between agents also leads to a consensus, accepted without doubts.
Summary: This book explores the connections of Randomness to other areas of scientific knowledge, especially its fruitful relationship to Computability and Complexity Theory, and also to areas such as Probability, Statistics, Information Theory, Biology, Physics, Quantum Mechanics, Learning Theory and Artificial Intelligence. The contributors cover these topics without neglecting important philosophical dimensions, sometimes going beyond the purely technical to formulate age old questions relating to matters such as determinism and free will. The scope of this book is novel. Each contributor shares their personal views and anecdotes on the various reasons and motivations which led them to the study of Randomness.
Fractal Time: Why a Watched Kettle Never Boils (Studies of Nonlinear Phenomena in Life Science), World Scientific Publishing Company
Summary: This book provides an interdisciplinary introduction to the notion of fractal time, starting from scratch with a philosophical and perceptual puzzle. How subjective duration varies, depending on the way we embed current content into contexts, is explained. The complexity of our temporal perspective depends on the number of nestings performed, i.e. on the number of contexts taken into account. (...) Recent research results are described which present and discuss a number of distorted temporal perspectives. (...) It would be of immense interest to anyone working in the fields of cognitive and complexity sciences, psychology and the neurosciences, social medicine, philosophy.
The Tell-Tale Brain: A Neuroscientist's Quest for What Makes Us Human, W. W. Norton & Company
Summary: In a major new work, Ramachandran sets his sights on the mystery of human uniqueness. Taking us to the frontiers of neurology, he reveals what extreme cases can teach us about normal brain function. Synesthesia becomes a window into the brain mechanisms that make some of us more creative than others. And autism, for which Ramachandran opens a new direction for treatment, gives us a glimpse of the aspect of being human that we understand least: self-awareness. Tracing the strange links between neurology and behavior, this book unveils a wealth of clues into the deepest mysteries of the human brain.
The Hidden Reality: Parallel Universes and the Deep Laws of the Cosmos, Knopf
Summary: In this new book, Brian Greene explores our most current understanding of the universe, its deepest laws of nature, and our continuing quest to know more. The Hidden Reality reveals how major developments in different branches of fundamental theoretical physicsâ€"relativistic, quantum, cosmological, unified, computational â€" have all led us to consider one or another variety of parallel universe. In some, they are separated from us by enormous stretches of space or time, in others theyâ€™re hovering millimetres away, in others still the very notion of their location proves to be a concept beyond our reach.

The Next Decade: Where We've Been . . . and Where We're Going, Doubleday
Summary: The next ten years will be a time of massive transition. The wars in the Islamic world will be subsiding, and terrorism will become something we learn to live with. China will be encountering its crisis. We will be moving from a time when financial crises dominate the world to a time when labor shortages will begin to dominate. The new century will be taking shape in the next decade. In The Next Decade, George Friedman offers readers a proÂ¬vocative and endlessly fascinating prognosis for the immediÂ¬ate future. (...)
