  1. Complex Systems, Complex Science: Meeting of Minds, IST Results Next Article Bookmark and Share

    Excerpts: Leading world experts gathered at the First European Conference on Complex Systems in Turin, Italy, in December to present their latest research results in this relatively new multidisciplinary domain.
    "There's nothing new about complex systems," says Dr John Casti, a project manager in the IST-funded EXYSTENCE Network of Excellence for Complex Systems. "They've been with us from the time our ancestors crawled up out of the sea. But what is new is that for perhaps the first time in history, we have the knowledge and the tools to study such systems in a controlled, repeatable, scientific fashion. So there is reason to believe that this new found capability will eventually lead to a viable theory of such systems."
    Within EXYSTENCE, Casti and his peers have written many articles about complex systems for non-specialists, which are posted on the network's website. Before EXYSTENCE ends in 2005, they hope to publish a roadmap document, which will identify and target opportunities for future research work and funding.

  2. Malaria Vaccines: Back to the Future?, Science Next Article Bookmark and Share

    Excerpts: Malaria is the scourge of many developing countries, particularly those in sub-Saharan Africa, claiming several million lives each year. Researchers have struggled for decades to make a successful subunit or attenuated whole-organism vaccine but with limited success. Factors that have hampered the development of a subunit vaccine include the complexity of the malaria life cycle, the wide variety of immune response induced by the malaria parasite, and an incomplete knowledge of protective immunity.

  3. A Theory for Long-Memory in Supply and Demand, SFI Working Papers Next Article Bookmark and Share

    Abstract: Recent empirical studies have demonstrated long-memory in the signs of orders to buy or sell in financial markets. We show how this can be caused by delays in market clearing. Under the common practice of order splitting, large orders are broken up into pieces and executed incrementally. If the size of such large orders is power law distributed, this gives rise to power law decaying autocorrelations in the signs of executed orders. More specifically, we show that if the cumulative distribution of large orders of volume v is proportional to valpha and the size of executed orders is constant, the autocorrelation of order signs is asymptotically proportional to tau^{-(alpha-1)}. This is a long-memory process when alpha < 2. With a few caveats, this gives a good match to the data. A version of the model also shows long-memory fluctuations in order execution rates, which may be relevant for explaining the long-memory of price diffusion rates.

    1. Modelling Manufacturing Evolution: Thoughts on Sustainable Industrial Development, Journal of Cleaner Production Next Article Bookmark and Share

      Abstract: With many tools available for industrial sustainability, it appears that problems now lie in implementation. Management uncertainties and other barriers are undermining progress toward sustainable industrial development. With the aim of modelling manufacturing evolution, this paper presents a study that integrates manufacturing cladistics, an evolutionary classification scheme from the biological sciences, with evolutionary systems modelling, from the physical sciences. The study highlights the problems associated with the implementation of new technologies and practices. This new approach is then evaluated in the context of sustainable manufacturing. The aim would be to guide transformations and explore the evolutionary differences between sustainable and non-sustainable organisations, and identify new structures offering industry novel solutions for sustainability.

    2. Growth, Trade And Uneven Development, Cambridge J. Econ. Next Article Bookmark and Share

      Abstract: Theories of growth and international trade are reviewed critically from the perspective of understanding persistent inter-country and inter-regional income inequality. Three separate literatures are considered for the insights they offer about international disparity: Classical political economy, the North-South trade models, and the 'new' growth and trade theories that incorporate increasing returns and/or product differentiation. Classical antecedents of the more recent theories are identified, and contrasts are drawn between structuralist and neoclassical approaches to explaining the income gap between rich and poor nations.

  4. Fuzzy Decision Making In Politics: A Linguistic Fuzzy-Set Approach, Political Analysis Next Article Bookmark and Share

    Excerpt: In this article I use linguistic fuzzy-set theory to analyze the process of decision making in politics. I first introduce a number of relevant elements of (numerical and linguistic) fuzzy-set theory that are needed to understand the terminology as well as to grasp the scope and depth of the approach. I then explicate a linguistic fuzzy-set approach (LFSA) to the process of decision making (...). The LFSA approach is illustrated through a running (hypothetical) example of a situation in which state leaders need to decide how to combine trust and power to make a choice on security alignment.

  5. Climate Modelers See Scorching Future as a Real Possibility, Science Next Article Bookmark and Share

    Excerpts: Researchers tapping the computer power of 26,000 idling personal computers are confirming that a searing heating of the globe in the coming centuries can't be ruled out. Their new twist is twofold. It could get even hotter than the previous worst case had it. And, contrary to earlier work, no modeler can yet say that such an extreme scenario is any less likely than the moderately strong warming that most climate scientists expect. That shakes up what had seemed to be an emerging consensus, (...).

    1. Climate Change 'Disaster By 2026', BBC News Next Article Bookmark and Share

      Excerpts: At current rates, the earth will be 2C above pre-industrial levels some time between 2026 and 2060, says the report by Dr Mark New of Oxford University.

      Temperatures in the Arctic could rise by three times this amount, it says.

      It would lead to a loss of summer sea ice and tundra vegetation, with polar bears and other animals dying out.

      It would also mean a fundamental change in the ways Inuit and other Arctic residents live.

  7. Sizing Up Complex Webs: Close Or Far, Many Networks Look The Same, Science News Next Article Bookmark and Share

    Excerpts:
    Fractal Burst. In the World Wide Web, links between individual nodes follow patterns similar to those of links between clusters of nodes, between clusters of clusters, and so on. Makse

    Researchers have discovered that a remarkable diversity of complex networks, including the World Wide Web and patterns in cellular biochemistry, have a common architecture with snowflakes and trees. These networks all display similar patterns, whether viewed from up close or far away.

    (...) mathematicians have modeled complex networks such as the World Wide Web as infinite dimensional because there's no realistic way to fit such a network, with hubs having so many links, into a finite-dimensional space. This property led Barabási and many other researchers to assume that complex networks cannot be self-similar.

    1. Complex Systems: Romanesque Networks, Nature Next Article Bookmark and Share

      Excerpts: Newly won evidence shows that many real-world network systems obey a power-law scaling, just as if they were fractal shapes. Could this be the harbinger of a new architectural law for complex systems?

    3. New Roads Can Cause Congestion, New Scientist Next Article Bookmark and Share

      Excerpts: Traffic should flow best in cities when only a limited number of roads lead to the centre. This counter-intuitive finding could allow planners to prevent gridlock by closing roads rather than building new ones.

      It comes from a new way of thinking about complex networks developed by Neil Johnson, Douglas Ashton and Timothy Jarrett at the University of Oxford, UK. The researchers began by approximating a complex city network to just a ring road and a number of the arterial roads that cross at the centre.

  8. Researchers Define Who We Are When We Work Together And The 'Wait And See' Approach, ScienceDaily Next Article Bookmark and Share

    Excerpt: Whether it is barn-raising or crafting a business plan, humans are among the few creatures that are able to work well cooperatively. According to an evolutionary psychologist at the University of Pennsylvania, our success at cooperation results from three distinct personality types. "In any given group of people, youl find three kinds of people: Cooperators, Free Riders, and what we call Reciprocators. Cooperators do the most work and Free Riders do as little as possible, but most of us are Reciprocators. We hold back a bit to determine the chances of success before devoting our full energy to a project," (...)

    1. Performance Without Anxiety, Scientific American Next Article Bookmark and Share

      Excerpts: Fear of reinforcing negative stereotypes, Claude Steele finds, hampers the ability to succeed. The idea is now central in affirmative action and job discrimination fights

      The roots of the concept trace back to a phenomenon Steele explored shortly after he began his academic career (...). It turned on the potent consequences of being judged negatively, even when the only basis was one's membership in a group. Researchers telephoned residents and made negative characterizations, such as "people in your community are lousy drivers."

  9. Working Memory, Psychiatric Symptoms, And Academic Performance At School, Neurobiol. Learning & Memory Next Article Bookmark and Share

    Excerpts: Previous studies of the relationship among working memory function, academic performance, and behavior in children have focused mainly on clinical populations. In the present study, the associations of the performance in audio- and visuospatial working memory tasks to teacher reported academic achievement and psychiatric symptoms were evaluated in a sample of fifty-five 6-13-year-old school children. (...) The results showed that good spatial working memory performance was associated with academic success at school. Children with low working memory performance, especially audiospatial memory, were reported to have more academic and attentional/behavioral difficulties at school than children with good working memory performance.

      To stimulate memory formation, an electrophysiological recording apparatus can both stimulate and record electrical signals from a 400-micron-thick slice of rat hippocampus.
      Some moments become lasting recollections while others just evaporate. The reason may involve the same processes that shape our brains to begin with

      Because one neuron can form tens of thousands of synaptic connections and there could not possibly be a gene dedicated to each one, cellular neuroscientists sought to explain how the cell nucleus was controlling the strength of these individual connections. They theorized that an unknown signaling molecule must be generated by a synapse when it was sufficiently stimulated.

    1. Phase Synchronization For The Recognition Of Mental Tasks In A Brain-Computer Interface, IEEE Tran. Neural Sys. & Rehab. Engg. Next Article Bookmark and Share

      Excerpt: Brain-computer interfaces (BCIs) may be a future communication channel for motor-disabled people. In surface electroencephalogram (EEG)-based BCIs, the extracted features are often derived from spectral estimates and autoregressive models. We examined the usefulness of synchronization between EEG signals for classifying mental tasks. (...) For sole use of synchronization measures, classification accuracies up to 62% were achieved. In general, the best result was obtained combining phase synchronization measures with$alpha$power spectral density estimates. The results demonstrate that phase synchronization provides relevant information for the classification of spontaneous EEG during mental tasks.

  11. Google's Search For Meaning, New Scientist Next Article Bookmark and Share

    Excerpts: (...) a Google search can be used to measure how closely two words relate to each other. For instance, imagine a computer needs to understand what a hat is.

    To do this, it needs to build a word tree - a database of how words relate to each other. It might start with any two words to see how they relate to each other. For example, if it googles "hat" and "head" together it gets nearly 9 million hits, compared to, say, fewer than half a million hits for "hat" and "banana".

    1. Seeking Better Web Searches, Scientific American Next Article Bookmark and Share

      Excerpts: Deluged with superfluous responses to online queries, users will soon benefit from improved search engines that deliver customized results.

      In less than a decade, Internet search engines have completely changed how people gather information. No longer must we run to a library to look up something; rather we can pull up relevant documents with just a few clicks on a keyboard. Now that "Googling" has become synonymous with doing research, online search engines are poised for a series of upgrades that promise to further enhance how we find what we need.

    Image: Yerkes National Primate Research Center
    Inequities big and small can lead people to believe that life is indeed not fair. But how humans respond to unfair situations depends on the social circumstances: inequality among friends and family, for instance, is less disturbing than it is among strangers. The results of a new study indicate that the same is true for chimpanzees, a finding that sheds light on how our sense of fairness evolved.

  14. An Eocene Big Bang for Bats, Science Next Article Bookmark and Share

    Excerpts: Bats, the only mammals capable of powered flight, constitute more than 20% of living mammal species. Unlike birds and other terrestrial vertebrates, most bats use echolocation --a biological form of sonar--to locate and track their prey. Bats are found on every continent except Antarctica, and they exploit a wide variety of food sources including insects, small vertebrates, fruit, nectar, pollen, and even blood. (...)

    Despite their prominent position among mammals, the evolutionary history of bats is largely unknown (...).

    Excerpts:
    Image: Courtesy Of Forterre And Mahadevan
    Taking just a tenth of a second, the snapping mechanism that a Venus fly trap uses to capture its prey is one of the fastest movements in the plant kingdom. Scientists have long wondered how the plant manages such a feat without muscles or nerves. The answer, according to results published today in the journal Nature, is by shapeshifting.

    1. How The Venus Flytrap Snaps, Nature Next Article Bookmark and Share

      Excerpts: The rapid closure of the Venus flytrap (Dionaea muscipula) leaf in about 100 ms is one of the fastest movements in the plant kingdom. This led Darwin to describe the plant as "one of the most wonderful in the world". The trap closure is initiated by the mechanical stimulation of trigger hairs. Previous studies have focused on the biochemical response of the trigger hairs to stimuli and quantified the propagation of action potentials in the leaves. Here we complement these studies by considering the post-stimulation mechanical aspects of Venus flytrap closure.

    Excerpts: Magnetic fields on a microchip can produce tiny, coherent clouds of atoms called Bose-Einstein condensates. The chips could have uses in ultraprecise sensors for aircraft and in quantum computing

    A century after its conception, quantum mechanics continues to be a disturbing theory. It tells us to think of all matter as waves, and yet in all objects that surround us these matter waves are far too small to be seen. Although the quantum laws are thought to be valid for objects of all sizes--from elementary particles to the universe as a whole--we do not usually see matter waves or any other quantum behavior in our everyday world.

    1. How to Create a Spin Current, Science Next Article Bookmark and Share

      Excerpts: A spin current differs from a charge current in two important ways. First, it is invariant under time reversal: If the clock ran backward, spin current would flow in the same direction. Second, spin current is associated with a flow of angular momentum, which is a vector quantity. This feature allows quantum information to be sent across semiconducting structures, just as quantum optics involves distribution of information across optical networks via polarization states of the photon.

    Excerpt: Better, faster medical care has reduced deaths from the more than 10,000 war injuries in Iraq and Afghanistan to the lowest percentage of any war in American history. In World War II, 30 percent of U.S. soldiers died from wounds received in combat; in Vietnam, 24 percent of the wounded died. In Iraq and Afghanistan, despite the horrific increase in the destructibility of weapons, mortality has dropped to 10 percent. But that's not entirely good news for the survivors. Injuries from suicide bombs and land mines often leave lifetime disabilities. Surgeons report a depressingly high incidence of blindness. (...)
