  1. Finding the Right Match, nobelprize.org Next Article Bookmark and Share

    Excerpt: As we all know, matching house buyers with those selling houses, or job seekers with the right vacancy, can be an inefficient process. This year's Laureates in Economic Sciences, Peter A. Diamond, Dale T. Mortensen and Christopher A. Pissarides, have created mathematical models which provide the framework for studying how such processes occur in the real world.

  2. Synthetic biology: Living quarters, Nature Next Article Bookmark and Share

    Excerpt:
    R. ARMSTRONG
    Surfaces containing artificial 'cells' that absorb carbon dioxide could make buildings greener.
    All complex life is composed of eukaryotic (nucleated) cells. The eukaryotic cell arose from prokaryotes just once in four billion years, and otherwise prokaryotes show no tendency to evolve greater complexity. Why not? Prokaryotic genome size is constrained by bioenergetics. The endosymbiosis that gave rise to mitochondria restructured the distribution of DNA in relation to bioenergetic membranes, permitting a remarkable 200,000-fold expansion in the number of genes expressed. This vast leap in genomic capacity was strictly dependent on mitochondrial power, and prerequisite to eukaryote complexity: the key innovation en route to multicellular life.

  3. Cities: The urban equation, Nature Next Article Bookmark and Share

    Excerpt: After spending tens of thousands of years living mostly in small settlements, humans have entered an urban stage of evolution. As of 2008, more than half the world's people live in cities, and the urban population is swelling by 1 million every week. By 2030, almost 6 in 10 people will live in metropolitan areas, which exert a powerful pull as economic and social magnets.

    1. A unified theory of urban living, Nature Next Article Bookmark and Share

      Excerpt: Cities are complex systems whose infrastructural, economic and social components are strongly interrelated and therefore difficult to understand in isolation3. The many problems associated with urban growth and global sustainability, however, are typically treated as independent issues. This frequently results in ineffective policy and often leads to unfortunate and sometimes disastrous unintended consequences. Policies meant to control population movements and the spread of slums in megacities, or to reverse urban decay, have largely proven ineffective or counterproductive, despite huge expenditure.

    2. Mathematics and Morphogenesis of the City, A Geometrical approach, arXiv Next Article Bookmark and Share

      Excerpt: Cities can be compared to living organisms. They are out of equilibrium, opened systems that never stop developing and sometimes die. The city’s growth is guided by needs in local distribution and in communication among its parts. The local geography can be compared to a shell constraining its development. In brief, a city’s current layout is a step in a running morphogenesis process. Thus cities display a huge diversity of shapes and none of traditional models from random graphs, complex networks theory or stochastic geometry takes into account geometrical, functional and dynamical aspects of a city in the same framework. We present here a global mathematical model dedicated to cities that permits describing, manipulating and explaining cities’ overall shape and layout of their street systems. (...)

    3. Environment: Mexico's scientist in chief, Nature Next Article Bookmark and Share

      Excerpt: Molina's great challenge is to help Mexico City to reach its goal of becoming the greenest megacity in Latin America. It is a tall order. This metropolis of more than 20 million people was once considered the most polluted urban area in the world.

  4. Twitter mood predicts the stock market, arXiv Next Article Bookmark and Share

    Excerpt: Behavioral economics tells us that emotions can profoundly affect individual behavior and decision-making. Does this also apply to societies at large, i.e., can societies experience mood states that affect their collective decision making? By extension is the public mood correlated or even predictive of economic indicators? Here we investigate whether measurements of collective mood states derived from large-scale Twitter feeds are correlated to the value of the Dow Jones Industrial Average (DJIA) over time. (...) We find an accuracy of 87.6% in predicting the daily up and down changes in the closing values of the DJIA and a reduction of the Mean Average Percentage Error by more than 6%.

    1. Spontaneous emergence of social influence in online systems, PNAS Next Article Bookmark and Share

      Excerpt: Social influence drives both offline and online human behavior. It pervades cultural markets, and manifests itself in the adoption of scientific and technical innovations as well as the spread of social practices. Prior empirical work on the diffusion of innovations in spatial regions or social networks has largely focused on the spread of one particular technology among a subset of all potential adopters. Here we choose an online context that allows us to study social influence processes by tracking the popularity of a complete set of applications installed by the user population of a social networking site, thus capturing the behavior of all individuals who can influence each other in this context. (...)

  5. Stefano Mancuso: The roots of plant intelligence, TED.com Next Article Bookmark and Share

    About this talk: Plants behave in some oddly intelligent ways: fighting predators, maximizing food opportunities ... But can we think of them as actually having a form of intelligence of their own? Italian botanist Stefano Mancuso presents intriguing evidence.

    1. Heribert Watzke: The brain in your gut, TED.com Next Article Bookmark and Share

      About this talk: Did you know you have functioning neurons in your intestines -- about a hundred million of them? Food scientist Heribert Watzke tells us about the "hidden brain" in our gut and the surprising things it makes us feel

  6. The Darwin/Gray Correspondence 1857â€"1869: An Intelligent Discussion about Chance and Design, Perspectives on Science Next Article Bookmark and Share

    Abstract: The nature and place of teleological explanation in evolutionary biology is a central topic, as is the nature and place of chance, randomness, and accident. But these topics are often treated as if they had no connection to each other. This was not always the case. In this paper I explore an intense discussion between Charles Darwin and American botanist Asa Gray, carried on in correspondence and in publications, about the compatibility of chance and teleology in Darwin's theory.

  7. The energetics of genome complexity, Nature Next Article Bookmark and Share

    Abstract: All complex life is composed of eukaryotic (nucleated) cells. The eukaryotic cell arose from prokaryotes just once in four billion years, and otherwise prokaryotes show no tendency to evolve greater complexity. Why not? Prokaryotic genome size is constrained by bioenergetics.

  8. Benoît B Mandelbrot: the man who made geometry an art, guardian.co.uk Next Article Bookmark and Share

    Excerpt: Few recent thinkers have woven such a beautiful braid of art and science as Benoît B Mandelbrot, who has died aged 85 in Cambridge, Massachusetts. (The B apparently doesn't stand for anything. He just felt like adding it.) Mandelbrot was a provocative mathematician, a subversive geometer. He left a beautiful legacy in visual art, for Mandelbrot was the man who named and explained fractals â€" those complex, apparently chaotic yet geometrically ordered shapes that delight the eye and fascinate the mind. They are icons of modern understanding of the universe's complexity.

  9. Sex, drugs and moral goals: reproductive strategies and views about recreational drugs, Proc. R. Soc. B Next Article Bookmark and Share

    Excerpt: [...] we look at the relationships among (i) abstract political commitments; (ii) attitudes about sexuality; and (iii) views surrounding recreational drugs. Whereas some theories suggest that drug views are best understood as the result of abstract political ideology, we suggest that these views can be better understood in the context of reproductive strategy.

  10. Europe's Migrants: 'The World Is a Smaller Place', Knowledge@Wharton Next Article Bookmark and Share

    Summary: France expels Roma Gypsies; a prominent German economist says migrants are destroying the country; a far-right party with an anti-immigration platform wins its first parliamentary seats in Sweden. Few countries in Europe have escaped the recent heated debates about immigration within their borders. Against this backdrop, a growing body of research is helping Europeans understand whether, and under what conditions, immigration is economically and socially beneficial. As one Wharton expert notes, "It's not a zero-sum game."

  11. Know thyself: Metacognitive networks and measures of consciousness, Cognition Next Article Bookmark and Share

    Abstract: Subjective measures of awareness rest on the assumption that conscious knowledge is knowledge that participants know they possess. Post-Decision Wagering (PDW), recently proposed as a new measure of awareness, requires participants to place a high or a low wager on their decisions. Whereas advantageous wagering indicates awareness of the knowledge on which the decisions are based, cases in which participants fail to optimize their wagers suggest performance without awareness. Here, we hypothesize that wagering and other subjective measures of awareness reflect metacognitive capacities subtended by self-developed metarepresentations that inform an agent about its own internal states. To support this idea, we present three simulations in which neural networks learn to wager on their own responses. The simulations illustrate essential properties that are required for such metarepresentations to influence PDW as a measure of awareness. Results demonstrate a good fit to human data. We discuss the implications of this modeling work for our understanding of consciousness and its measures.

  12. The Benefits of Multilingualism, Science Next Article Bookmark and Share

    Excerpt: Multilingualismâ€"the ability to understand and speak several languagesâ€"is exceptional in the United States but common elsewhere, especially in small-scale traditional societies. For instance, once while I was camped with some New Guinea Highlanders conversing simultaneously in several local languages, I asked each man to name each language in which he could converse. It turned out that everyone present spoke at least 5 languages, and the champion was a man who spoke 15. What are the cognitive effects of such multilingualism? Recent studies show that children raised bilingually develop a specific type of cognitive benefit during infancy, and that bilingualism offers some protection against symptoms of Alzheimer's dementia in old people.

  13. Publish your computer code: it is good enough, Nature Next Article Bookmark and Share

    Excerpt: That the code is a little raw is one of the main reasons scientists give for not sharing it with others. Yet, software in all trades is written to be good enough for the job intended. So if your code is good enough to do the job, then it is good enough to release â€" and releasing it will help your research and your field.

  14. Evolutionary game theory in growing populations, arXiv Next Article Bookmark and Share

    Abstract: Existing theoretical models of evolution focus on the relative fitness advantages of different mutants in a population while the dynamic behavior of the population size is mostly left unconsidered. We here present a generic stochastic model which combines the growth dynamics of the population and its internal evolution. Our model thereby accounts for the fact that both evolutionary and growth dynamics are based on individual reproduction events and hence are highly coupled and stochastic in nature. We exemplify our approach by studying the dilemma of cooperation in growing populations and show that genuinely stochastic events can ease the dilemma by leading to a transient but robust increase in cooperation.

    1. Universality of weak selection, arXiv Next Article Bookmark and Share

      Excerpt: Weak selection, which means a phenotype is slightly advantageous over another, is an important limiting case in evolutionary biology. Recently it has been introduced into evolutionary game theory. In evolutionary game dynamics, the probability to be imitated or to reproduce depends on the performance in a game. The influence of the game on the stochastic dynamics in finite populations is governed by the intensity of selection. (...)

    2. Cooperation in the snowdrift game on directed small-world networks under self-questioning and noisy conditions, Computer Physics Communications Next Article Bookmark and Share

      Excerpt: Cooperation in the evolutionary snowdrift game with a self-questioning updating mechanism is studied on annealed and quenched small-world networks with directed couplings. (...) Fair amounts of noise were found to break the observed symmetry and further weaken cooperation at relatively large values of r. However, in the absence of noise, the self-questioning mechanism recovers symmetrical behavior and elevates altruism even under large-reward conditions. Our results suggest that an updating mechanism of this type is necessary to stabilize cooperation in a spatially structured environment which is otherwise detrimental to cooperative behavior, especially at high cost-to-benefit ratios. Additionally, we employ component and local stability analyses to better understand the nature of the manifested dynamics.

  15. Saturation Probabilities of Continuous-Time Sigmoidal Networks, arXiv Next Article Bookmark and Share

    Abstract: From genetic regulatory networks to nervous systems, the interactions between elements in biological networks often take a sigmoidal or S-shaped form. This paper develops a probabilistic characterization of the parameter space of continuous-time sigmoidal networks (CTSNs), a simple but dynamically-universal model of such interactions. We describe an efficient and accurate method for calculating the probability of observing effectively M-dimensional dynamics in an N-element CTSN, as well as a closed-form but approximate method. We then study the dependence of this probability on N, M, and the parameter ranges over which sampling occurs. This analysis provides insight into the overall structure of CTSN parameter space.

  16. A Note on Rationalizability and Restrictions on Beliefs, The B.E. Journal of Theoretical Economics Next Article Bookmark and Share

    Excerpt: Rationalizability is a widely accepted solution concept in the study of strategic-form games with complete information [...] I focus on games with incomplete information and characterize Delta-rationalizability with a new notion of iterative dominance that is able to capture the additional hypothesis on players' beliefs.

  17. Two-dimensional ranking of Wikipedia articles, Eur. Phys. J. B Next Article Bookmark and Share

    Abstract: The Library of Babel, described by Jorge Luis Borges, stores an enormous amount of information. The Library exists ab aeterno. Wikipedia, a free online encyclopaedia, becomes a modern analogue of such a Library. Information retrieval and ranking of Wikipedia articles become the challenge of modern society. While PageRank highlights very well known nodes with many ingoing links, CheiRank highlights very communicative nodes with many outgoing links. In this way the ranking becomes two-dimensional. Using CheiRank and PageRank we analyze the properties of two-dimensional ranking of all Wikipedia English articles and show that it gives their reliable classification with rich and nontrivial features. Detailed studies are done for countries, universities, personalities, physicists, chess players, Dow-Jones companies and other categories.

  18. Von Neumann's Methodology of Science: From Incompleteness Theorems to Later Foundational Reflections, Perspectives on Science Next Article Bookmark and Share

    Abstract: In spite of the many efforts made to clarify von Neumann's methodology of science, one crucial point seems to have been disregarded in recent literature: his closeness to Hilbert's spirit. In this paper I shall claim that the scientific methodology adopted by von Neumann in his later foundational reflections originates in the attempt to revaluate Hilbert's axiomatics in the light of Gödel's incompleteness theorems. Indeed, axiomatics continues to be pursued by the Hungarian mathematician in the spirit of Hilbert's school. I shall argue this point by examining four basic ideas embraced by von Neumann in his foundational considerations: a) the conservative attitude to assume in mathematics; b) the role that mathematics and the axiomatic approach have to play in all that is science; c) the notion of success as an alternative methodological criterion to follow in scientific research; d) the empirical and, at the same time, abstract nature of mathematical thought. Once these four basic ideas have been accepted, Hilbert's spirit in von Neumann's methodology of science will become clear.

      Summary:
      Drawing examples from mathematics, physics, chemistry, biology, engineering, economics, medicine, politics, and sports, this book illustrates how nonlinear dynamics plays a vital role in our world. Examples cover a wide range from the spread and possible control of communicable diseases, to the lack of predictability in long-range weather forecasting, to competition between political groups and nations. After an introductory chapter that explores what it means to be nonlinear, the book covers the mathematical concepts such as limit cycles, fractals, chaos, bifurcations, and solitons, that will be applied throughout the book.

      Summary:
      We are living in an ever more complex world, an epoch where human actions can accordingly acquire far-reaching potentialities. Complex and adaptive dynamical systems are ubiquitous in the world surrounding us and require us to adapt to new realities and the way of dealing with them. This primer has been developed with the aim of conveying a wide range of "commons-sense" knowledge in the field of quantitative complex system science at an introductory level, providing an entry point to this both fascinating and vitally important subject.

    4. Academic Units in a Complex, Changing World: Adaptation and Resistance, Springer Next Article Bookmark and Share

      Summary:
      This book uses case studies of academic units from Australian public universities to explore the reasons why those units respond in different ways to similar contemporary challenges. The ‘academic units’â€"departments, schools and facultiesâ€"in the world’s public universities may be their own administrative fiefdoms, but the wider environment within which they operate is both complex and dynamic. In fact, today’s academic landscape is barely recognizable from what it was like two decades ago. The globalization of higher education markets for students, faculty and research funding has expanded the challenges and opportunities for academic units. (...)

    5. Biophysics of DNA-Protein Interactions: From Single Molecules to Biological Systems, Springer Next Article Bookmark and Share

      Summary:
      Depite the rapid expansion of the field of biophysics, there are very few books that comprehensively treat specific topics in this area. Recently, the field of single molecule biophysics has developed very quickly, and a few books specifically treating single molecule methods are beginning to appear. However, the promise of single molecule biophysics is to contribute to the understanding of specific fields of biology using new methods. This book would focus on the specific topic of the biophysics of DNA-protein interactions, and would include the use of new approaches, including both bulk methods as well as single molecule methods.
