  1. Controllability of complex networks, Nature Next Article Bookmark and Share

    Abstract: The ultimate proof of our understanding of natural or technological systems is reflected in our ability to control them. Although control theory offers mathematical tools for steering engineered and natural systems towards a desired state, a framework to control complex self-organized systems is lacking. Here we develop analytical tools to study the controllability of an arbitrary complex directed network, identifying the set of driver nodes with time-dependent control that can guide the system’s entire dynamics. We apply these tools to several real networks, finding that the number of driver nodes is determined mainly by the network’s degree distribution. We show that sparse inhomogeneous networks, which emerge in many real complex systems, are the most difficult to control, but that dense and homogeneous networks can be controlled using a few driver nodes. Counterintuitively, we find that in both model and real systems the driver nodes tend to avoid the high-degree nodes.

    1. How Structure Determines Correlations in Neuronal Networks, PLoS Comput Biol Next Article Bookmark and Share

      Excerpt: Many biological systems have been described as networks whose complex properties influence the behaviour of the system. Correlations of activity in such networks are of interest in a variety of fields, from gene-regulatory networks to neuroscience. (...) We present a detailed explanation of how recurrent connectivity induces correlations in local neural networks and how structural features affect their size and distribution. We examine under which conditions network characteristics like distance dependent connectivity, hubs or patches markedly influence correlations and population signals.

  2. Differences Between Tight and Loose Cultures: A 33-Nation Study, Science Next Article Bookmark and Share

    Abstract: With data from 33 nations, we illustrate the differences between cultures that are tight (have many strong norms and a low tolerance of deviant behavior) versus loose (have weak social norms and a high tolerance of deviant behavior). Tightness-looseness is part of a complex, loosely integrated multilevel system that comprises distal ecological and historical threats (e.g., high population density, resource scarcity, a history of territorial conflict, and disease and environmental threats), broad versus narrow socialization in societal institutions (e.g., autocracy, media regulations), the strength of everyday recurring situations, and micro-level psychological affordances (e.g., prevention self-guides, high regulatory strength, need for structure). This research advances knowledge that can foster cross-cultural understanding in a world of increasing global interdependence and has implications for modeling cultural change.

  3. Synthetic genomes: The next step for the synthetic genome, Nature Next Article Bookmark and Share

    Excerpt: Synthetic biology often adopts the language of engineers: rather than talking about genes, networks and biosynthetic pathways, practitioners prefer to talk about parts, devices and modules. 'Parts' refer to the protein-coding section of a gene and sundry regulatory sequences that tune gene expression. A 'device' is an assembly of parts that together perform a particular function, often turning a protein's production on or off. And a 'module' or pathway is a collection of devices that carry out more-complex functions, such as coordinating a chemical synthesis or shunting cells between 'growth' and 'production' modes.
    Editor's Note: One of the major hurdles of synthetic biology seen as engineering is that components are not isolated. One can have 'modules' with desired functions, but one cannot predict what will happen when they are introduced in the same cell. Interactions can change the expected behavior of components.

  4. On the Role of Free Will in Predictive Models of Human Behavior, NECSI Next Article Bookmark and Share

    Excerpt: Trying to understand social systems forces us to wrestle with the concept of free will. Does free will make it impossible to build models that reliably predict what human beings will do? We have tried to do so nonetheless.

      About this talk: Medical ethicist Harvey Fineberg shows us three paths forward for the ever-evolving human species: to stop evolving completely, to evolve naturally -- or to control the next steps of human evolution, using genetic modification, to make ourselves smarter, faster, better. Neo-evolution is within our grasp. What will we do with it?

  6. The Implications of Interactions for Science and Philosophy, arXiv Next Article Bookmark and Share

    Abstract: Reductionism has dominated science and philosophy for centuries. Complexity has recently shown that interactions---which reductionism neglects---are relevant for understanding phenomena. When interactions are considered, reductionism becomes limited in several aspects. In this paper, I argue that interactions imply non-reductionism, non-materialism, non-predictability, non-Platonism, and non-nihilism. As alternatives to each of these, holism, informism, adaptation, contextuality, and meaningfulness are put forward, respectively. A worldview that includes interactions not only describes better our world, but can help to solve many open scientific, philosophical, and social problems caused by implications of reductionism.

  7. Time-Ordered Networks Reveal Limitations to Information Flow in Ant Colonies, PLoS ONE Next Article Bookmark and Share

    Excerpt: Using thousands of time-stamped interactions between uniquely marked ants in four colonies of a range of sizes, we demonstrate that observed maximum rates of information flow are always slower than predicted, and are constrained by regulation of individual mobility and contact rate. By accounting for the ordering and timing of interactions, we can resolve important difficulties with network sampling frequency and duration, enabling a broader understanding of interaction network functioning across systems and scales.

  8. Self-Organized Discrimination of Resources, PLoS ONE Next Article Bookmark and Share

    Excerpt: When selecting a resource to exploit, an insect colony must take into account at least two constraints [...] Following recent results on cockroaches and ants, we introduce here a behavioral mechanism that satisfies these two constraints. Individuals simply modulate their probability to switch to another resource as a function of the local density of conspecifics locally detected. As a result, the individuals gather at the smallest resource that can host the whole group,[...]

  9. Universal Entropy of Word Ordering Across Linguistic Families, PLoS ONE Next Article Bookmark and Share

    Excerpt: Our results indicate that despite the differences in the structure and vocabulary of the languages analyzed, the impact of word ordering in the structure of language is a statistical linguistic universal.

  10. Growth and Optimality in Network Evolution, arXiv Next Article Bookmark and Share

    Abstract: In this paper we investigate networks whose evolution is governed by the interaction of a random assembly process and an optimization process. In the first process, new nodes are added one at a time and form connections to randomly selected old nodes. In between node additions, the network is rewired to minimize its pathlength. For timescales, at which neither the assembly nor the optimization processes are dominant, we find a rich variety of complex networks with power law tails in the degree distributions. These networks also exhibit non-trivial clustering, a hierarchical organization and interesting degree mixing patterns.

  11. Dynamical Patterns of Cattle Trade Movements, PLoS ONE Next Article Bookmark and Share

    Excerpt: (...) Traditional static views of the displacement network hide important patterns of structural changes affecting nodes' centrality and farms' spreading potential, thus limiting the efficiency of interventions based on partial longitudinal information. By fully taking into account the longitudinal dimension, we propose a novel definition of dynamical motifs that is able to uncover the presence of a temporal arrow describing the evolution of the system and the causality patterns of its displacements, shedding light on mechanisms that may play a crucial role in the definition of preventive actions.

    1. Evolution of scaling emergence in large-scale spatial epidemic spreading, arXiv Next Article Bookmark and Share

      Excerpt: The analyses of large-scale spatial epidemic spreading help understand the temporal evolution of scalings, indicating the coexistence of the Zipf's law and the Heaps' law depends on the collective dynamics of epidemic processes, and the heterogeneity of epidemic spread indicates the significance of performing targeted containment strategies at the early time of a pandemic disease.

  12. How Citation Boosts Promote Scientific Paradigm Shifts and Nobel Prizes, PLoS ONE Next Article Bookmark and Share

    Excerpt: Nobel Prizes are commonly seen to be among the most prestigious achievements of our times. Based on mining several million citations, we quantitatively analyze the processes driving paradigm shifts in science. We find that groundbreaking discoveries of Nobel Prize Laureates and other famous scientists are not only acknowledged by many citations of their landmark papers. Surprisingly, they also boost the citation rates of their previous publications. Given that innovations must outcompete the rich-gets-richer effect for scientific citations, it turns out that they can make their way only through citation cascades. A quantitative analysis reveals how and why they happen. Science appears to behave like a self-organized critical system, in which citation cascades of all sizes occur (...)

  13. Evolution of adaptive phenotypic variation patterns by direct selection for evolvability, Proc. R. Soc. B Next Article Bookmark and Share

    Excerpt: A basic assumption of the Darwinian theory of evolution is that heritable variation arises randomly. In this context, randomness means that mutations arise irrespective of the current adaptive needs imposed by the environment. It is broadly accepted, however, that phenotypic variation is not uniformly distributed among phenotypic traits, some traits tend to covary, while others vary independently, and again others barely vary at all.

    1. Non-adaptive origins of interactome complexity, Nature Next Article Bookmark and Share

      Excerpt: The boundaries between prokaryotes, unicellular eukaryotes and multicellular eukaryotes are accompanied by orders-of-magnitude reductions in effective population size, with concurrent amplifications of the effects of random genetic drift and mutation (...) Here we demonstrate a phylogenetically broad inverse relation between the power of drift and the structural integrity of protein subunits. This leads to the hypothesis that the accumulation of mildly deleterious mutations in populations of small size induces secondary selection for protein"protein interactions that stabilize key gene functions. By this means, the complex protein architectures and interactions essential to the genesis of phenotypic diversity may initially emerge by non-adaptive mechanisms.

  14. The Alchemical Revolution, Science Next Article Bookmark and Share

    Abstract: A growing number of science historians hold that alchemists""chymists" is their preferred, less-loaded term"were serious scientists who kept careful lab notes and followed the scientific method as well as any modern researcher and are testing that hypothesis by recreating their experiments. If the alchemists saw what they claimed, these researchers say, then it's high time for an "alchemical revolution" to restore them to scientific respectability. In the view of these advocates, alchemists have been unjustly ranked with witches and mountebank performers, when in fact they were educated men with limited tools for inquiring into the nature of the universe.

  15. Emergence of coherent motion in aggregates of motile coupled maps, arXiv Next Article Bookmark and Share

    Abstract: In this paper we study the emergence of coherence in collective motion described by a system of interacting motiles endowed with an inner, adaptative, steering mechanism. By means of a nonlinear parametric coupling, the system elements are able to swing along the route to chaos. Thereby, each motile can display different types of behavior, i.e. from ordered to fully erratic motion, accordingly with its surrounding conditions. The appearance of patterns of collective motion is shown to be related to the emergence of interparticle synchronization and the degree of coherence of motion is quantified by means of a graph representation. The effects related to the density of particles and to interparticle distances are explored. It is shown that the higher degrees of coherence and group cohesion are attained when the system elements display a combination of ordered and chaotic behaviors, which emerges from a collective self-organization process.

  16. Cellular automaton supercolliders, arXiv Next Article Bookmark and Share

    Abstract: Gliders in one-dimensional cellular automata are compact groups of non-quiescent and non-ether patterns (ether represents a periodic background) translating along automaton lattice. They are cellular-automaton analogous of localizations or quasi-local collective excitations travelling in a spatially extended non-linear medium. They can be considered as binary strings or symbols travelling along a one-dimensional ring, interacting with each other and changing their states, or symbolic values, as a result of interactions. We analyse what types of interaction occur between gliders travelling on a cellular automaton `cyclotron' and build a catalog of the most common reactions. We demonstrate that collisions between gliders emulate the basic types of interaction that occur between localizations in non-linear media: fusion, elastic collision, and soliton-like collision. Computational outcomes of a swarm of gliders circling on a one-dimensional torus are analysed via implementation of cyclic tag systems.

  17. Stability Criteria for Complex Ecosystems, arXiv Next Article Bookmark and Share

    Abstract: Forty years ago, Robert May questioned a central belief in ecology by proving that sufficiently large or complex ecological networks have probability of persisting close to zero. To prove this point, he analyzed large networks in which species interact at random. However, in natural systems pairs of species have well-defined interactions (e.g., predator-prey, mutualistic or competitive). Here we extend May's results to these relationships and find remarkable differences between predator-prey interactions, which increase stability, and mutualistic and competitive, which are destabilizing. We provide analytic stability criteria for all cases. These results have broad applicability in ecology. For example, we show that, surprisingly, the probability of stability for predator-prey networks is decreased when we impose realistic food web structure or we introduce a large preponderance of weak interactions. Similarly, stability is negatively impacted by nestedness in bipartite mutualistic networks.

  18. From genes to games: Cooperation and cyclic dominance in meiotic drive, Journal of Theoretical Biology Next Article Bookmark and Share

    Excerpt: Evolutionary change can be described on a genotypic level or a phenotypic level. Evolutionary game theory is typically thought of as a phenotypic approach, although it is frequently argued that it can also be used to describe population genetic evolution. Interpreting the interaction between alleles in a diploid genome as a two player game leads to interesting alternative perspectives on genetic evolution. Here we focus on the case of meiotic drive and illustrate how meiotic drive can be directly and precisely interpreted as a social dilemma, such as the prisoners dilemma or the snowdrift game,...

      Summary:
      Bayes' rule appears to be a straightforward, one-line theorem: by updating our initial beliefs with objective new information, we get a new and improved belief. To its adherents, it is an elegant statement about learning from experience. To its opponents, it is subjectivity run amok. In the first-ever account of Bayes' rule for general readers, Sharon Bertsch McGrayne explores this controversial theorem and the human obsessions surrounding it.

      Summary:
      Of all neurological disorders, epilepsy demands of investigators the broadest and deepest knowledge of dynamical, control, and system theories, knowledge that cannot be amassed without possessing a certain level of sophistication in relevant areas of neurosciences, physics, mathematics, and engineering. Narrowing the inescapable cultural chasm that commonly fragments multidisciplinary efforts, this book captures and enriches the burgeoning interdisciplinary synergism in the nascent field of dynamical epileptology.
