  1. A Theory Of Power-Law Distributions In Financial Market Fluctuations, Nature Next Article Bookmark and Share

    Excerpts: Insights into the dynamics of a complex system are often gained by focusing on large fluctuations. For the financial system, huge databases now exist that facilitate the analysis of large fluctuations and the characterization of their statistical behaviour. Power laws appear to describe histograms of relevant financial fluctuations, such as fluctuations in stock price, trading volume and the number of trades. (...) Here we propose a model, based on a plausible set of assumptions, which provides an explanation for these empirical power laws.

  2. Altruisitic Duality in Evolutionary Game Theory, arXiv Next Article Bookmark and Share

    Abstract: A game-theoretic model of social preference and enlightened self-interest is formulated. Existence of symmetry and duality in the game matrices with altruistic social preference is revealed. The model is able to quantitatively describe the dynamical evolution of altruism in prisoner's dilemma and the regime change in prey-predator dynamics.

  3. Dynamics Of Social Networks, Complexity Next Article Bookmark and Share

    Abstract: Complex networks such as the World Wide Web (...) often do not have an engineered architecture but instead are self-organized by the actions of a large number of individuals. From these local interactions nontrivial global phenomena can emerge as small-world properties or scale-free degree distributions. A simple model for the evolution of acquaintance networks highlights the essential dynamical ingredients necessary to obtain such complex network structures. The model generates highly clustered networks with small average path lengths and scale-free as well as exponential degree distributions. It compares well with experimental data of social networks(...).

  4. Information Flow in Social Groups, arXiv Next Article Bookmark and Share

    Abstract: We present a study of information flow that takes into account the observation that an item relevant to one person is more likely to be of interest to individuals in the same social circle than those outside of it. This is due to the fact that the similarity of node attributes in social networks decreases as a function of the graph distance. An epidemic model on a scale-free network with this property has a finite threshold, implying that the spread of information is limited. We tested our predictions by measuring the spread of messages in an organization and also by numerical experiments that take into consideration the organizational distance among individuals.

    1. Decentralized Decision-Making In A Large Team With Local Information, Games & Econ. Behav. Next Article Bookmark and Share

      Abstract: We study a problem involving a team of agents each associated with a node in a chain. Each agent makes a decision that influences only his own cost and those of adjacent agents. Prior to making his decision, each agent observes only the cost structure associated with nodes that can be reached by traversing no more than r arcs. We show that (...) deterministic strategies require r to be proportional to the number of agents. This means that the amount of information accessible to any agent should be proportional to the total number of agents.

    2. Copied citations create renowned papers?, arXiv Next Article Bookmark and Share

      Abstract: Recently we discovered (cond-mat/0212043) that the majority of scientific citations are copied from the lists of references used in other papers. Here we show that a model, in which a scientist picks three random papers, cites them,and also copies a quarter of their references accounts quantitatively for empirically observed citation distribution. Simple mathematical probability, not genius, can explain why some papers are cited a lot more than the other.

  5. Attractor Dynamics Of Network UP States In The Neocortex, Nature Next Article Bookmark and Share

    Excerpt: The cerebral cortex receives input from lower brain regions. (...) Moreover, the membrane potential of cortical neurons fluctuates spontaneously between a resting (DOWN) and a depolarized (UP) state, which may also be coordinated. (...) Here we report the occurrence of synchronized UP state transitions ('cortical flashes') that occur in spatially organized ensembles involving small numbers of neurons. Because of their stereotyped spatiotemporal dynamics, we conclude that network UP states are circuit attractorsˇXemergent features of feedback neural networks that could implement memory states or solutions to computational problems.

    1. Turning On And Off Recurrent Balanced Cortical Activity, Nature Next Article Bookmark and Share

      Excerpt: The vast majority of synaptic connections onto neurons in the cerebral cortex arise from other cortical neurons, both excitatory and inhibitory, forming local and distant 'recurrent' networks. (...) local cortical circuits do indeed operate through a proportional balance of excitation and inhibition generated through local recurrent connections, and that the operation of such circuits can generate self-sustaining activity that can be turned on and off by synaptic inputs. These results confirm the long-hypothesized role of recurrent activity as a basic operation of the cerebral cortex.

    2. Neocortical Mechanisms In Motor Learning, Current Opinion in Neurobiol. Next Article Bookmark and Share

      Abstract: The ability to learn novel motor skills has fundamental importance for adaptive behavior. Neocortical mechanisms support human motor skill learning, from simple practice to adaptation and arbitrary sensory-motor associations. Behavioral and neural manifestations of motor learning evolve in time and involve multiple structures across the neocortex. Modifications of neural properties, synchrony and synaptic efficacy are all related to the development and maintenance of motor skill.

  6. The Dark Side Of The Genome Researchers Shine Their Lights On Noncoding Sequence, The Scientist Next Article Bookmark and Share

    Excerpts: She offers possible explanations, including novel genes, transcripts derived from alternative splicing, antisense RNA, and intergenic transcripts. In the past, she says, many have attributed such findings to PCR artifacts. "The experimental work that we've done in the laboratory ... indicates that these low-level transcripts are really valid," she says. Referring to the genome's nonprotein-coding elements as "our own dark matter," she asks: "Is there a whole world within the nucleus about which we're fairly ignorant?"

  7. Mental Self: The Person Within, Nature Next Article Bookmark and Share

    Excerpts: (...) define the concept of 'self', (...). One would be refreshingly precise: "what the immune system identifies as belonging to the body", a topic that was ably tackled by Gus Nossal in an earlier essay in this series. The other meaning, corresponding to the everyday idea of mental self, would be more difficult to pin down. The answers would include: "the sense of one's own being", or "the sum total of qualities that distinguish the mind of one person from that of another", or "one's personal identity".

    1. The Self As An Embedded Agent, Minds & Machines Next Article Bookmark and Share

      Abstract: In this paper we consider the concept of a self-aware agent. In cognitive science agents are seen as embodied and interactively situated in worlds. We analyse the meanings attached to these terms in cognitive science and robotics, proposing a set of conditions for situatedness and embodiment, and examine the claim that internal representational schemas are largely unnecessary for intelligent behaviour in animats. We maintain that current situated and embodied animats cannot be ascribed even minimal self-awareness (...). We propose that self-aware agents must possess complex structures of self-directed goals; multi-modal sensory systems and a rich repertoire of interactions with their worlds.

  8. Alzheimer's Vaccine Passes Key Test, CNN News Next Article Bookmark and Share

    Excerpts: An experimental vaccine designed to fight Alzheimer's disease appears to be safe in humans and is showing an immune response, according to scientists with Elan Corporation.(...) Alzheimer's is a degenerative disease of the brain that inexorably attacks nerve cells, causing impairment and loss of memory and mental functions. Worldwide, 22 million people are expected to develop the disease by the year 2025.(...) The vaccine is designed to attack and clear out the characteristic beta amyloid plaques seen in the brains of Alzheimer's patients. There is still some debate over whether the amyloid plaques are the cause of Alzheimer's dementia.

    1. New Type Of Vaccine Against Nicotine Addiction Developed By TSRI Scientists, Scripps Research Institute Next Article Bookmark and Share

      Excerpts: Scientists at The Scripps Research Institute (TSRI) have designed a new way to make vaccines against drugs of abuse that could become a valuable tool for treating addiction by helping the body clear the drug from the bloodstream. The latest vaccine they created using this approach induces the body to clear nicotine.(...) The new idea that they have developed is to take a chemical that resembles nicotine and use it to induce an active immune response. In this immune response, the body produces antibodies against nicotine that can neutralize it in the bloodstream. If a smoker later smokes a cigarette, the antibodies will clear the nicotine from the system before it reaches the brain.

  9. Self-Repairing Computers, Scientific American Next Article Bookmark and Share

    Excerpts: Our group (...) has taken a new tack, by accepting that computer failure and human operator error are facts of life. Rather than trying to eliminate computer crashes--(...) --our team concentrates on designing systems that recover rapidly when mishaps do occur. We call our approach recovery-oriented computing (ROC). We decided to focus our efforts on improving Internet site software. This kind of highly dynamic computing system must evolve and expand quickly in response to consumer demands and market pressures--while also serving users who expect instant access at any time.

    1. Towards A Neurally-Inspired Computer Architecture, Natural Computing Next Article Bookmark and Share

      Abstract: The first two main rounds of neural computing focused on adaptation and self-organization in neural networks, and on use of analog VLSI for compartmental modeling of the neuron, respectively. This paper is a prospectus for a third round of neural computing: analyzing the architecture of the primate brain to extract neural information processing principles and translate them into biologically-inspired operating systems and computer architectures. The way in which the cerebellum interacts with other brain regions in learning how to better control and coordinate movements provides a case study to introduce key ideas for these three rounds of neural computation.

    2. Humans Deceived By Predatory Stealth Strategy Camouflaging Motion, Alphagalileo & Biol. Lett. Next Article Bookmark and Share

      Abstract: Motion camouflage is a stealth strategy that allows a predator to conceal its apparent motion as it approaches a moving prey. This letter presents the implementation and results of a sychophysical experiment suggesting that humans are susceptible to motion camouflage. The experiment masqueraded as a computer game competition. Players were deceived by motion camouflage predators controlled by artificial neural systems operating using realistic levels of input information. It is suggested that these results are especially of interest to biologists, visual psychophysicists, military engineers and computer games designers.

  10. The Complexities Of Skeletal Biology, Nature Next Article Bookmark and Share

    Abstract: For a long time, the skeleton was seen as an amorphous tissue of little biological interest. But such a view ignored the large number of genetic and degenerative diseases affecting this organ. Over the past 15 years, molecular and genetic studies have modified our understanding of skeletal biology. By so doing this progress has affected our understanding of diseases and suggested in many instances new therapeutic opportunities.

  11. Cosmology: A Just-So Story, Nature Next Article Bookmark and Share

    Excerpt: But perhaps the most significant change in cosmological thinking involves a new willingness to discuss (...): the anthropic principle. This idea suggests that the precise values of various fundamental parameters describing our Universe might be understood only as a consequence of the fact that we exist to measure them. To paraphrase the cosmologist Andrei Linde, "If the Universe were populated everywhere by intelligent fish, they might wonder why it was full of water. Well, if it weren't, they wouldn't be around to observe it!".

    1. Chaos-Assisted Capture Of Irregular Moons, Nature Next Article Bookmark and Share

      Excerpt: It has been thought that the capture of irregular moonsˇXwith non-circular orbitsˇXby giant planets occurs by a process in which they are first temporarily trapped by gravity inside the planet's Hill sphere (the region where planetary gravity dominates over solar tides). The capture of the moons is then made permanent by dissipative energy loss (for example, gas drag) or planetary growth. (...) Here we show that irregular satellites are captured in a thin spatial region where orbits are chaotic, (...).

  12. Telescopes of the World, Unite! A Cosmic Database Emerges, NYTimes Next Article Bookmark and Share

    Excerpt: (...) assemble what some of them were calling "the world's best telescope." (...). Within minutes, to their joy and astonishment, they had discovered three or four brown dwarfs, objects that occupy the niche between planet and star. (...) The telescope that Dr. Szalay and his colleagues have constructed is not built of glass and metal. It is a virtual observatory, consisting of terabytes of data collected by dozens of telescopes on Earth and in space, and the software necessary to mine these data for scientific gems.

  13. Some Scientists Think SARS May Have Come from Outer Space, Reuters Next Article Bookmark and Share

    Excerpts: Instead of jumping from an unknown animal host in southern China, a few researchers in Britain believe the virus that has baffled medical experts descended from the stratosphere. "I think it is a possibility that SARS came from space. It is a very strong possibility," Professor Chandra Wickramasinghe told Reuters. The director of the Cardiff Center for Astrobiology in Wales and a proponent of the theory that life on Earth originated from space, admits the theory defies conventional wisdom.

  14. Mild Stress Increases Longevity, The Scientist Next Article Bookmark and Share

    Excerpts: Aging is a nonadaptive process resulting from cumulative damage in cells, and the genes that control oxidative or other damage may have an effect on the timescale of the aging process. Insulin also has a role in the modulation of longevity, (...). This gene has multiple targets that could be involved in modulating the several functions of the insulin-signaling pathway. (...) a molecule important in modulating heat shock response also has a role in the control of aging and (...) may work together to promote longevity.

  15. Automatic Thematic Extractor, J. Intell. Info. Sys. Next Article Bookmark and Share

    Abstract: We have created a system that identifies musical "keywords" or themes. The system searches for all patterns composed of melodic repetition in a piece. This process generally uncovers a large number of patterns, many of which are either uninteresting or only superficially important. Filters reduce the number or prevalence, or both, of such patterns. Patterns are then rated according to perceptually significant characteristics. The top-ranked patterns correspond to important thematic or motivic musical content, as has been verified by comparisons with published musical thematic catalogs. The system operates robustly across a broad range of styles, (...).

    1. Music Information Retrieval, J. Intell. Info. Sys. Next Article Bookmark and Share

      Abstract: Increasing availability of music data via Internet evokes demand for efficient search through music files. Users' interests include melody tracking, harmonic structure analysis, timbre identification, and so on. We visualize, in an illustrative example, why content based search is needed for music data and what difficulties must be overcame to build an intelligent music information retrieval system.

  16. Aerosols' Effects Could Change Current Understanding Of Global Climate Change, ScienceDaily Next Article Bookmark and Share

    Excerpts: Atmospheric aerosols, airborne particles that reflect the sun's heat away from Earth and into space, are part of everyday life. They are in the haze of air pollution, in plumes of smoke from forest fires and in ash clouds from erupting volcanoes. But a new study says the cooling effect of man-made aerosols could throw a monkey wrench into the current understanding of climate change. "It's possible that the total forcing from human activity to date is small, or even negative. That's unlikely but possible, and we should not rule it out at this point."

  17. Scientists Discover How the Monarch Butterfly Navigates 2,000-mile Migration Without a Map, The Independent Next Article Bookmark and Share

    Excerpts: Scientists have solved one of natures most enduring mysteries - how the monarch butterfly is able to navigate more than 2,000 miles on its annual migration route.(...)
    Monarch butterflies migrate between their wintering roosts in central Mexico to their summer breeding grounds as far north as the US-Canadian border. Scientists have now discovered that they employ an internal biological clock that enables them to use the sun as a reliable compass no matter what time of day it is.
    This form of navigation is so accurate that it allows some monarch butterflies to return to the same trees in the Mexican mountains that were used by their great, great grandparents as roosting sites the previous winter.
    Contributing Editor's Note:: The understanding of the navigation mechanisms which insects and other animals use has inspired the design of machines which are able to navigate using the same mechanisms. (See also: ALife8 webcasts)

  18. Iraq'S Slide Into Lawlessness Squanders Good Will For U.S., NYTimes Next Article Bookmark and Share

    Excerpts: In the space of a few weeks, awe at American power in war has been transformed into anger at American impotence in peace. A crime wave, increasingly the work of organized gangs far better armed than the skeleton Iraqi police forces, has kept citizens (...), free yet fearful. Delays in restoring electricity and telecommunications have kept businesses closed. Banks, looted of at least $500 million in deposits, have yet to reopen. Traders, attacked daily by armed bands on the highway linking Iraq to Jordan, are reluctant to send much needed imports.

      Excerpts: The Pentagon is about to embark on a stunningly ambitious research project designed to gather every conceivable bit of information about a person's life, index all the information and make it searchable. (...) The embryonic LifeLog program would dump everything an individual does into a giant database: every e-mail sent or received, every picture taken, every Web page surfed, every phone call made, every TV show watched, every magazine read. All of this -- and more -- would combine with information gleaned from a variety of sources (...)

    3. Walk This Way, NYTimes Next Article Bookmark and Share

      Excerpts: One of the technologies the Pentagon is working on, as The A.P.'s Michael Sniffen reported, is a radar-based device that can identify people by the way they walk for use in a new antiterrorist surveillance system. "Operating on the theory that an individual's walk is as unique as a signature, the Pentagon has financed a research project at the Georgia Institute of Technology that has been 80 to 95 percent successful in identifying people," he wrote.
