    1. Catastrophic cascade of failures in interdependent networks, Nature Bookmark and Share

      Excerpt: Complex networks have been studied intensively for a decade, but research still focuses on the limited case of a single, non-interacting network. Modern systems are coupled together and therefore should be modelled as interdependent networks. A fundamental property of interdependent networks is that failure of nodes in one network may lead to failure of dependent nodes in other networks. This may happen recursively and can lead to a cascade of failures.

    Excerpt:
    BuRSTS is a performance in human dynamics, a game of cooperation and prediction, that will gradually unveil the full text of Bursts. In a nutshell, if you register at http://brsts.com, you will be able to adopt one of the 84,245 words of the book. Once you adopt, the words adopted by others will become visible to you -- thus as each words finds a parent, the whole book will become visible to the adopters. But if you invite your friends (and please do!) and you are good at predicting hidden content, the book will unveil itself to you well before all words are adopted. We will even send each day free signed copied of Bursts to those with the best scores.

    1. An Informative Itinerary, Science Bookmark and Share

      Excerpt:
      Melanie Mitchell (...) takes us on a personal guided tour in Complexity. I emphasize personal because Mitchell (a computer scientist at Portland State University and SFI) uses her experience in evolutionary computation and artificial life to paint her picture of the history, and current state, of complexity research. Also, she writes in an unpretentious style with frequent entertaining and useful anecdotes that make one feel she is a trusted companion on the tour. Lastly, she focuses predominantly on computational aspects, with ecology, economics, and (perhaps surprisingly) neuroscience being notably less emphasized.

  3. On the Algorithmic Nature of the World, arXiv Bookmark and Share

    Abstract: We propose a test based on the theory of algorithmic complexity and an experimental evaluation of Levin's universal distribution to identify evidence in support of or in contravention of the claim that the world is algorithmic in nature. To this end we have undertaken a statistical comparison of the frequency distributions of data from physical sources on the one hand--repositories of information such as images, data stored in a hard drive, computer programs and DNA sequences--and the frequency distributions generated by purely algorithmic means on the other--by running abstract computing devices such as Turing machines, cellular automata and Post Tag systems. Statistical correlations were found and their significance measured.

  6. Evolution of cooperation by natural selection, arXiv Bookmark and Share

    Excerpt: The observed cooperation on the level of genes, cells, tissues, and individuals has been the object of intense study by evolutionary biologists,(...) We find that if stochastic strategies for the iterated Prisoner’s Dilemma (IPD) are encoded as genes, the environmental conditions that the strategies are adapting to determine the fixed point of the evolutionary trajectory. (...) These results imply that previous identifications of mechanisms that promote cooperation can be understood within a broader framework where increased predictability is sufficient for the evolution of cooperation

    Excerpt: One year ago this month, the world watched with trepidation as a novel influenza A virus, to which the global population had little or no immunity, emerged in Mexico and the United States. In the weeks that followed, the H1N1 'swine flu' virus spread rapidly to countries worldwide, leading the World Health Organization (WHO) on 11 June 2009 to officially declare the first flu pandemic in more than 40 years. Nature looks at the lessons learnt from H1N1, and how they will help scientists and health authorities to handle the next flu pandemic.

  10. Coding and decoding in the Evolution of communication: Information richness and Referentiality, arXiv Bookmark and Share

    Excerpts: One of the most basic properties of the communicative sign is its dual nature. That is, a sign is a twofold entity composed of a formal component, which we call signal, and a referential component, namely a reference. Based on this conception, we say that a referent is coded in a particular sign, or that a sign is decoded in a particular referent. (...) the referentiality of a signal must be preserved after being decoded, due to a selective pressure. Despite the information-theoretic flavour of this requirement, an inquiry into classical concepts of information theory such as entropy or mutual information will lead us to the conclusion that information theory as usually stated does not account for this very important requirement that natural communication systems must satisfy. Motivated by the relevance of the preservation of referentiality in evolution, we will fill this gap from a theoretical viewpoint (...)

    Excerpt: Even though all these trees are the same species, Malus x domestica, the apple, there's no end to the variety of shapes and postures they assume. Glenn, trim, white-haired, points out that some trees grow vertically like elms, while some droop like willows. Some have branches with elbows and right angles, still others lack a central trunk and sprout stalks like bamboo. And that's only part of the variety he'll see when their fruit arrives in late April. Cross two adult fruit trees"a wild variety resistant to disease, say, and a domesticated one with sweet fruit"and there's almost no telling what you'll get.

  13. Competition encourages cooperation: client fish receive higher-quality service when cleaner fish compete, Animal Behaviour Bookmark and Share

    Excerpt: Partner choice is likely to be an important mechanism for the maintenance of cooperation in many mutualisms, and cleaner mutualisms among fish have been a model system for testing predictions of partner choice theories. [...]The results indicate that cleaners give ornate butterflyfish, Chaetodon ornatissimus, priority of access to their services when these clients can switch partners; however, ornate butterflyfish are not cheated less often when they have access to multiple cleaner stations, and they frequently respond to cheating by aggressively chasing cleaners. In combination with previous work, these results indicate that partner choice influences cooperative interactions between bluestreak cleaner wrasse and their clients, but that some clients with the ability to switch partners may use other strategies (i.e. punishment) to limit cheating by cleaners.

  14. Complexity and Diversity, Science Bookmark and Share

    Abstract: The mechanisms for the origin and maintenance of biological diversity are not fully understood. It is known that frequency-dependent selection, generating advantages for rare types, can maintain genetic variation and lead to speciation, but in models with simple phenotypes (that is, low-dimensional phenotype spaces), frequency dependence needs to be strong to generate diversity. However, we show that if the ecological properties of an organism are determined by multiple traits with complex interactions, the conditions needed for frequency-dependent selection to generate diversity are relaxed to the point where they are easily satisfied in high-dimensional phenotype spaces. Mathematically, this phenomenon is reflected in properties of eigenvalues of quadratic forms. Because all living organisms have at least hundreds of phenotypes, this casts the potential importance of frequency dependence for the origin and maintenance of diversity in a new light.

  15. Hierarchical modularity in human brain functional networks, arXiv Bookmark and Share

    Excerpt: The idea that complex systems have a hierarchical modular organization originates in the early 1960s and has recently attracted fresh support from quantitative studies of large scale, real-life networks. Here we investigate the hierarchical modular (or "modules-within-modules") decomposition of human brain functional networks, (...) Results show that human brain functional networks have a hierarchical modular organization with a fair degree of similarity between subjects, I=0.63.(...) We conclude that methods are available for hierarchical modular decomposition of large numbers of high resolution brain functional networks using computationally expedient algorithms. This could enable future investigations of Simon's original hypothesis that hierarchy or near-decomposability of physical symbol systems is a critical design feature for their fast adaptivity to changing environmental conditions.

      Summary:
      What are organizations? What is their point? How should one design successful organizations? Although these questions have been treated by many authors in many different ways, this book offers a new perspective. In a nutshell, the book combines cybernetics, social systems theory and Aristotle’s ethics to describe organizations as "social systems conducting experiments with their survival" and to formulate principles for their design. The authors argue that ‘experimenting’ and ‘social interaction’ are key features of organizations. In order to survive, organizations continuously have to experiment with goals, infrastructures and transformation processes and this experiment is an inherently social activity. (...)

      The goal of this ground-breaking volume is to present how neuroscience research is relevant to sociologists and social psychologists as well as examining those areas of neuroscience that can refine and broaden sociological theory. The study of the brain and its effect on behavior grew to prominence in the mid-20th century. Neuroscientists and psychologists worked together in this area in the behavioral sciences but neuroscience has not had a big impact in sociology and the social sciences. Recently, neuroscientists have presented new research which has a direct impact on many areas of sociology. (...)

      Summary:
      Three centuries ago Montmort and De Moivre published two of the first books on probability theory, then called the doctrine of chances, emphasizing its most important application at that time, games of chance. This volume, on the probabilistic aspects of gambling, is a modern version of those classics. While covering the classical material such as house advantage and gambler's ruin, it also takes up such 20th-century topics as martingales, Markov chains, game theory, bold play, and optimal proportional play. In addition there is extensive coverage of specific casino games such as roulette, craps, video poker, baccarat, and twenty-one.
