  2. Monetary Policy under Uncertainty, The Federal Reserve Board Next Article Bookmark and Share

    Excerpts: Despite the extensive efforts to capture and quantify these key macroeconomic relationships, our knowledge about many of the important linkages is far from complete and in all likelihood will always remain so. Every model, no matter how detailed or how well designed conceptually and empirically, is a vastly simplified representation of the world that we experience with all its intricacies on a day-to-day basis. Consequently, even with large advances in computational capabilities and greater comprehension of economic linkages, our knowledge base is barely able to keep pace with the ever-increasing complexity of our global economy.

  3. The Dark Side of Cooperation, Science Now Next Article Bookmark and Share

    Excerpts: Legumes such as soybeans prosper from the services of soil bacteria called rhizobia. Dwelling in nodules on the plant's roots, (...). In turn, the plant offers nutrients and regulates oxygen needed for rhizobia to grow and reproduce. It sounds like a win-win situation, but often several strains of rhizobia provide nitrogen for the plant--and compete with one another. Rhizobia investing their energy and resources on their own growth and reproduction instead of nitrogen conversion would seemingly come out ahead, so why do the rhizobia keep putting out?

    1. Towards A Non-Darwinian Theory Of Institutional Change, J. Bioecon. Next Article Bookmark and Share

      Abstract: The paper emphasizes two flaws in mainstream economics: the failure to understand actual human behavior in many real contexts and the failure to take account of transaction costs. This article does not deny the validity of the Darwinian view applied to the theory of the firm and of competition in a free-market economy. The paper, however, maintains that the natural-selection process that characterizes the Darwinian approach is ill suited to describe economic evolutionary processes. It is shown that a combination of functional analysis and natural selection may indeed be a better solution, (...).

  4. Congestion And Centrality In Traffic Flow On Complex Networks, Adv. in Complex Sys. Next Article Bookmark and Share

    Abstract: The central points of communication network flow have often been identified using graph theoretical centrality measures. In real networks, the state of traffic density arises from an interplay between the dynamics of the flow and the underlying network structure. In this work we investigate the relationship between centrality measures and the density of traffic for some simple particle hopping models on networks with emerging scale-free degree distributions. (...) we find that, even at low traffic densities, the dynamical measure of traffic density (the occupation ratio) has a non-trivial dependence on the static centrality (...).

  5. Ant Book Deepens Divide Over Web Publishing, Nature Next Article Bookmark and Share

    Excerpts: A disagreement about ants has highlighted increasing conflict between biologists and book publishers over the release of scientific monographs in print and online. Brian Fisher, an entomologist at the California Academy of Sciences in San Francisco, is pressing for permission to publish data about ant species on the Internet. Under the terms of a book deal he signed last August with Harvard University Press, he cannot put material from his forthcoming monograph online for at least four years after it is printed.

  6. Technologies to Support the Creation of Complex Systems Models--Using StarLogo Software with Students, Biosystems Next Article Bookmark and Share

    Abstract: Research on complex, adaptive systems has made significant advances in recent years in the study of natural and social phenomena that exhibit random variation and selection, resulting in learning or evolution. Unfortunately, students (including K-12, undergraduate and graduate) in most biology programs have little opportunity to explore complex systems during the course of their studies. StarLogo and the Adventures in Modeling Curriculum [Adventures in Modeling: Exploring Complex, Dynamic Systems with StarLogo. Teachers College Press, New York] provide an easily accessible entry point into complex systems modeling for students and other novice modelers. These specialized tools can provide powerful insights into the dynamics of systems and create opportunities to explore challenging and meaningful domains in the biological sciences. Specific applications to epidemiological and ecological systems are explored, including the often debated topic of the evolution of reduced attack rates in predator-prey systems.

  7. Gene Gives Right-handers Clockwise Swirls: Study, Hindustan Times Next Article Bookmark and Share

    Excerpts: New research reveals that a gene could be the cause as to why right-handed people tend to have hair that swirls clockwise.(...)According to Amar Klar (the National Cancer Institute in Frederick in Maryland), says a report in Nature, a single gene with either 'right' or 'random' forms is responsible for the trend. People with one or two copies of the right version are likely to be right-handed, with clockwise hair while those with two random versions would split 50/50 for handedness and hair whorls. "It's one of the most exciting things [I've seen] in a while," says geneticist Ralph Greenspan of the Neurosciences Institute in San Diego, California. According to him, such a gene could lead to asymmetry throughout the body.

  8. Stem Cells May Eliminate Need for Heart Transplant, Heart Center Online, Reuters Next Article Bookmark and Share

    Excerpts: Four out of a group of five seriously ill Brazilian heart-failure patients no longer needed a heart transplant after being treated with their own stem cells, the doctor in charge of the research said Monday. Such "regenerative medicine," in which stem cells extracted from patients' own bone marrow are used to rebuild tissue, may one day become commonplace for patients with damaged or diseased hearts, some doctors believe.(...) Their treatment involved taking cells from bone marrow and injecting them into the heart's left ventricle, the main pumping chamber. Heart failure is the inability of damaged heart muscle to pump enough blood around the body.(...) The exact mechanism of action is not understood but medics believe stem cells harvested from bone marrow or blood may be able to form new muscle and blood vessels. Alternatively, they may trigger a chemical reaction that improves the functioning of cells in the locality of the injection.

  9. A Perspective on Enzyme Catalysis, Science Next Article Bookmark and Share

    Abstract: The seminal hypotheses proposed over the years for enzymatic catalysis are scrutinized. The historical record is explored from both biochemical and theoretical perspectives. Particular attention is given to the impact of molecular motions within the protein on the enzyme's catalytic properties. A case study for the enzyme dihydrofolate reductase provides evidence for coupled networks of predominantly conserved residues that influence the protein structure and motion. Such coupled networks have important implications for the origin and evolution of enzymes, as well as for protein engineering.

  10. Electric Field Effect In Correlated Oxide Systems, Nature Next Article Bookmark and Share

    Excerpts: Semiconducting field-effect transistors are the workhorses of the modern electronics era. Recently, application of the field-effect approach to compounds other than semiconductors has created opportunities to electrostatically modulate types of correlated electron behaviour-including high-temperature superconductivity and colossal magnetoresistance-and potentially tune the phase transitions in such systems. Here we provide an overview of the achievements in this field (...). These devices work by modulating the electrical charge carrier density, and hence electrical resistance, of a thin semiconducting channel through the application of an electric field. Editor's Note: One might speculate if field-effects might be relevant for biological information processing through field induced transitions in membranes.

  11. Mars: The Devil Is In The Dust, Nature Next Article Bookmark and Share

    Excerpts: Mars is a highly dynamic planet - at least as far as dust is concerned. A better knowledge of how dust is lofted into the atmosphere will help to untangle the complex evolutionary history of the planet's surface. (...) Dust transport is a key to the long-term evolution of the martian surface, (...). Although flowing water is believed to be responsible for some of this surface change, lifting and redistribution of dust by wind has had an important role over that entire period, and may be the largest factor today.

  12. Mind-Expanding Machines, Science News Next Article Bookmark and Share

    Excerpts: Cognitive prostheses represent a more active, mind-expanding approach to human-centered computing than Brooks' project does, (...). (...) aircraft pilots simulate flight with unaccustomed ease because they see their surroundings in a new light. (...) In a single image spread across a standard computer screen, OZ shows all the information needed to control an aircraft. An OZ display taps into both a person's central and peripheral vision. The pilot's eyes need not move from one gauge to another, says Still.

    1. Key Brain Link In Associative Learning Directly Observed, ScienceDaily Next Article Bookmark and Share

      Excerpts: Scientists have directly demonstrated in rats that one area of the brain can support the creation of memories by changing nerve cell firing patterns in another part of the brain, aiding the animal's efforts to predict the outcome of an action based on past experience and act on that prediction. The process, one scientist says, is something like what happens when a comic strip character sees something and is immediately reminded of something else. "There's a neural representation of something in the mind that is invoked by the environment, but not yet present in the environment."

  13. Chilly Future May Await Tomorrow's Computers, NewsFactor Network Next Article Bookmark and Share

    Excerpts: A "chill pill" that Slovenian computer scientists recently formulated "could ... allow quantum computers to operate at incredible speeds successfully," (...) A digital "deep freeze" may be the only way to save computers of the future from sizzling speeds that could burn out even the most robust microchips and hard drives. (...) Calling their chilling cure a "quantum freeze of fidelity," Tomaz Prosen and Marko Znidaric from the University of Ljubljana say that under certain conditions, their solution successfully eliminates a whole set of quantum errors.

  14. The Emergence Of Communication In Evolutionary Robots, Phil. Tran. Math., Phy. & Eng. Sc. Next Article Bookmark and Share

    Abstract: Evolutionary robotics is a biologically inspired approach to robotics that is advantageous to studying the evolution of communication. A new model for the emergence of communication is developed (...). In the first simulation, the emergence of simple signalling behaviour is studied. This is used to investigate (...) linguistic production and comprehension, and other behavioural skills. The model supports the hypothesis that the ability to form categories from direct interaction with an environment constitutes the grounds for subsequent evolution of communication and language. In the second simulation, evolutionary robots are used to study the emergence of simple syntactic categories, e.g. action names (verbs).

  15. Turbulence: Suddenly It's Chaos, Nature Next Article Bookmark and Share

    Excerpts: Injecting vortices into a rotating sample of superfluid helium-3 shows a sudden switch from smooth to chaotic behaviour, and throws light on turbulence - one of the last unsolved problems of classical physics. (...) This group is studying vortices in the simplest of fluids, superfluid helium. In a normal liquid the constituent particles are distributed over many possible quantum-mechanical energy states. Constant collisions ensure that the behaviour on a microscopic level is a frantic redistribution of particles among the available states.

    1. Chaos: Useful at Last?, Science Next Article Bookmark and Share

      Excerpts: (...) it thus came as quite a shock to buy a new microwave oven and find that it had a "chaos defrost" setting. This setting is indeed based on "chaos theory," the popular name for nonlinear dynamics. A simple chaotic system is used to generate an irregular heating sequence, which can reduce the time required to defrost food by up to 60% (1). The use of nonlinear dynamics may not be essential in this particular application: (...) Nonetheless, it shows that nonlinear dynamics is becoming useful in practical applications.

  16. Self-organised Criticality--What It Is and What It Isn't, Studies In History and Philosophy of Science Part A Next Article Bookmark and Share

    Abstract: The last decade and a half has seen an ardent development of self-organised criticality (SOC), a new approach to complex systems, which has become important in many domains of natural as well as social science, such as geology, biology, astronomy, and economics, to mention just a few. This has led many to adopt a generalist stance towards SOC, which is now repeatedly claimed to be a universal theory of complex behaviour. The aim of this paper is twofold. First, I provide a brief and non-technical introduction to SOC. Second, I critically discuss the various bold claims that have been made in connection with it. Throughout, I will adopt a rather sober attitude and argue that some people have been too readily carried away by fancy contentions. My overall conclusion will be that none of these bold claims can be maintained. Nevertheless, stripped of exaggerated expectations and daring assertions, many SOC models are interesting vehicles for promising scientific research.

  17. Pattern Formation And Stochastic Motion Of Zooplankton In A Light Field, Physica A Next Article Bookmark and Share

    Abstract: We extend our study of single and collective motions of the zooplankton Daphnia both in experiment and computer simulation. Daphnia, as well as many other prey animals, can be observed to swarm under certain circumstances as a protective behavior against predators. Daphnia swarms can be induced by an optical marker such as a vertical shaft of light, to which they are attracted. For low Daphnia densities we observe that individual Daphnia develop a circular motion around the optical marker, whereas for high densities we can reproducibly induce swarming Daphnia to carry out a vortex motion. To learn more about this circular pattern and the associated spontaneous symmetry breaking, the motion of single Daphnia, as well as swarms, is characterized with respect to the light shaft. A stochastic model based on experimental data is compared with the observed Daphnia behavior as well as with existing models for single agents and agent swarms performing a circular motion to reveal the essential ingredients for vortex motion to occur.

  18. Mechanics: Friction In A Spin, Nature Next Article Bookmark and Share

    Excerpts: The mechanics of friction may seem the stuff of high-school physics, but (...). A spinning coin is the subject of a new exploration of frictional forces. (...) Take a coin and launch it across your desk, recording the distance travelled. Now spin the coin about the axis perpendicular to its surface as you launch it (...) the coin will travel farther, even if launched with the same initial velocity. Furthermore, the coin will stop moving and stop spinning at exactly the same instant. Why?

  19. Complex Challenges: Global Terrorist Networks Next Article Bookmark and Share

    1. Future Watch: Using Computers To Outthink Terrorists, ComputerWorld Next Article Bookmark and Share

      Excerpts: Some of the technology shown in last year's blockbuster movie Minority Report may soon be a reality and a centerpiece of the intelligence community's war on terrorism. In the futuristic thriller, Tom Cruise played the head of a police unit that uses psychic technology to arrest and convict murderers before they commit their crimes. Research into new intelligence technology is taking place as part of a $54 million program known as Genoa II, a follow-on to the Genoa I program, which focused on intelligence analysis.

    2. Iraq Bombings Pose a Mystery U.S. Must Solve, NYTimes Next Article Bookmark and Share

      Excerpts: Hundreds, if not thousands, of insurgents from Saddam Hussein's former government have organized into cells, especially in the Sunni-dominated areas in and around Baghdad, to resist the United States-led occupation, American intelligence officials say. The nature of their resistance is clouded by the presence of hundreds of criminals freed from Iraqi jails just before the war, and as many as 1,000 foreign fighters, mainly Islamic militants, who have filtered into Iraq from Iran, Saudi Arabia, Syria and Jordan. Some are suspected of having ties to Al Qaeda, (...). Editor's Note: Have the coalition forces involuntarily created the world's largest terrorist training camp?

    3. The Media and the War on Terrorism, Brookings Institution Panel Next Article Bookmark and Share

      Excerpts: The book emerges from 20 sessions, at which journalists, war correspondents, present and former government officials and scholars discussed the special roles and responsibilities of journalists in the coverage of modern day terrorism. Hess and Kalb read and edited the transcripts and wrote introductions to the book itself and each chapter in the book, ranging from lessons of wars past to the dangers of biological warfare, from the attacks on New York and the Pentagon to the wars in Afghanistan and Iraq.

    4. Superworm To Storm The Net On 9/11, GuluFuture.com Next Article Bookmark and Share

      Excerpts: Our analysis of Internet virus activity, shows that on September 11th next, an advanced worm attack is set to infiltrate the Internet and could potentially halt email traffic worldwide. (...) The worm invasion will feature distributed denial-of-service (DDoS) attacks against Microsoft's website and those of anti-virus software vendors or spam prevention websites. This will hinder distribution of removal tools and prevent detection of worm spam. The SuperWorm would combine the capabilities of recent worms/viruses. This hi-tech worm could lever itself into becoming a "WormNet" inside the existing Internet, (...).
