  2. Neural Maps In Remote Sensing Image Analysis, Neural Networks Next Article Bookmark and Share

    Abstract: We study the application of self-organizing maps (SOMs) for the analyses of remote sensing spectral images. Advanced airborne and satellite-based imaging spectrometers produce very high-dimensional spectral signatures that provide key information to many scientific investigations about the surface and atmosphere of Earth and other planets. These new, sophisticated data demand new and advanced approaches to cluster detection, visualization, and supervised classification. In this article we concentrate on the issue of faithful topological mapping in order to avoid false interpretations of cluster maps created by an SOM. We describe several new extensions of the standard SOM (...).

    1. Scale-Free Networks, Scientific American Next Article Bookmark and Share

      Excerpt: Networks are everywhere. The brain is a network of nerve cells connected by axons, and cells themselves are networks of molecules connected by biochemical reactions. Societies, too, are networks of people linked by friendships, familial relationships and professional ties. On a larger scale, food webs and ecosystems can be represented as networks of species. And networks pervade technology: the Internet, power grids and transportation systems are but a few examples. Even the language we are using to convey these thoughts to you is a network, made up of words connected by syntactic relationships.

    2. Internet Access for the Cost of a Cup of Coffee, NYTimes Next Article Bookmark and Share

      Excerpts: Mr. Wooley said each restaurant spent about $2,000 to get its Wi-Fi up and running, and another $300 to $500 a month for the high-speed communications line that provides the wireless access network to the Internet. His reasoning is similar to Ms. Griffith's, but on a larger scale. Schlotzsky's surveys over the past few months have shown that 6 percent of customers go to Schlotzsky's for the free Wi-Fi. That translates to 15,000 customers per store per year. (...) "That's a really good return on investment," Mr. Wooley said.

  3. Web-Based Attacks Could Create Chaos In The Physical World, ScienceDaily Next Article Bookmark and Share

    Excerpts: Most experts on computer crime focus on attacks against Web servers, bank account tampering and other mischief confined to the digital world. But by using little more than a Web search engine and some simple software, a computer-savvy criminal or terrorist could easily leap beyond the boundaries of cyberspace to wreak havoc in the physical world, a team of Internet security researchers has concluded. (...) described how automated order forms on the Web could be exploited to send tens of thousands of unwanted catalogs to a business or an individual.

  4. Cellular Manufacturing Theory, strategy+business Next Article Bookmark and Share

    Excerpts: For the better part of the last century, the most commonly used metaphor in the business world was that of the machine. (...) people were cogs performing their work amid complex corporate structures and processes. (...), this dominant metaphor has increasingly been challenged, often by those seeking to apply principles of biology to engineering. Most comparisons between manufacturing and biological cells focus on their similarities - both cells and modern factories employ lean production systems, emphasize sourcing of high-quality materials, and use common components to make the production process as straightforward as possible.

    1. Leadership and Change, What Makes Southwest Airlines Fly, Knowledge@Wharton Next Article Bookmark and Share

      Excerpts: How does Southwest Airlines keep making money? After all, the airline industry overall is in a shambles. US Airways and United Air Lines are reorganizing in bankruptcy while American Airlines flirts with the same fate. As a group, the nation's biggest air carriers have lost tens of millions of dollars over the past several years, with no immediate recovery in sight. Yet the secret to its success, said Southwest chairman Herb Kelleher during a talk at Wharton April 22, is available for anyone, including its competitors, to see.

    2. Of Happy And Hapless Regulators: The Asymptotics Of Ruin, Insurance: Math. & Econ. Next Article Bookmark and Share

      Abstract: We employ a simple single-period ruin probability as a useful tool for studying various asymptotic effects associated with increasing the number of exposure units, n, covered by an insurer. These effects include: the law of large numbers, the roles of (...). For a model with known parameters, we find the necessary and sufficient condition for the ruin probability to converge to zero, as well as sufficient conditions for the normal approximation to provide asymptotically accurate comparative statics with respect to n. For a model with parameter-estimation errors, we find that the normal approximation no longer holds in general (...).

  5. The Global-Brand Advantage, MIT Sloan Management Review Next Article Bookmark and Share

    Abstract: Consumer attitudes toward globalness are evolving, and marketers should be wary of changes in both new and existing geographic markets. Steenkamp expects ethnocentrism to change over time. Many countries have become more accepting of nonlocal foods, for example, as the French have. And Alden says that as global brands become icons of a global consumer culture in various locales, he expects brand globalness to have a more direct impact on purchase likelihood. So global brand marketers may gain an advantage over time, even if they can't associate their brands with quality or prestige. (...) Though companies seem to be pushing their brands across borders increasingly, they aren't all driven by the notion that locals will embrace global brands. Businesses globalize their brands for other reasons, points out Batra, including to achieve economies of scale in production, logistics and communications. But marketers have to think about how consumers will embrace their products. And to reach consumers, quality is job one.

  6. Prebiotic Soup--Revisiting the Miller Experiment, Science Next Article Bookmark and Share

    Summary: Modern research in prebiotic chemistry effectively began with a publication of a paper in Science 50 years ago by Stanley L. Miller on the spark discharge synthesis of amino acids and other compounds using a mixture of reduced gases that were thought to represent the components of the atmosphere on the primitive Earth. On the anniversary of this milestone publication, Bada and Lazcano provide an account of the events surrounding the publication of the paper and discuss the historical studies that led up to the Miller experiment.

  7. Genetics: Suicidal Mushroom Cells, Nature Next Article Bookmark and Share

    Excerpts: Programmed cell death - apoptosis - is a universal phenomenon among multicellular organisms, and is especially important during development. Genetically orchestrated mechanisms of cell death have also been found in single-celled protists and yeast. (...), Benjamin Lu and colleagues describe a remarkably simple version of apoptosis in the ink-cap mushroom Coprinus cinereus (...) It turns out that, in the mutants, basidia that experience problems at the beginning of meiosis (prophase I) undergo mass apoptosis, showing the classical apoptotic hallmark of DNA fragmentation.

    1. Dying Cells Dragged Screaming Under The Microscope, Nature Next Article Bookmark and Share

      Excerpts: An eerie high-pitched song fills the air in a physics laboratory in Los Angeles. It is the scream of a yeast cell as it withers in a pool of alcohol, and it just may proclaim a useful new technique for cell biologists. (...) have been looking closely at how the outer membranes of yeast cells vibrate, depending on the condition of the cells. (...) whether this signature song could be used to monitor the health of a cell in response to both external stresses and internal ones, such as gene mutations.

  8. Salamanders Can Do Maths, Nature Science Update Next Article Bookmark and Share

    Excerpts: Salamanders, given a choice between tubes containing two fruitflies or three, lunge at the tube of three. This hints that the ability to differentiate between small numbers of objects may have evolved much earlier than scientists had thought.
    Primates can spot the greater of two quantities smaller than four, without any training. Babies choose the bowl with more cookies; monkeys go for the bucket with more slices of apple.
    The surprise, says Claudia Uller, of the University of Louisiana at Lafayette who carried out the study, was that the amphibians "failed in the same way that babies and monkeys do" - more than three objects confuses them.

  9. Self-Sacrificing Gall Repair By Aphid Nymphs, Alphagalileo & Biol. Lett. Next Article Bookmark and Share

    Abstract: Insect galls are vulnerable to invasion by moth larvae that can tunnel the wall. We report that nymphs of the aphid Nipponaphis monzeni repair their gall self-sacrificingly. When a hole was bored into their gall, many globular nymphs discharged a large amount of body fluid onto the gall''s wound, and kneaded the fluid, which soon became viscous and eventually congealed, plastering over the hole. Having discharged the fluid, the nymphs shrivelled to approximately 1/3 of their original volume. Several nymphs were buried in the plaster, like "aphid sacrifices". This is the most elaborate social behaviour so far known among aphids.

  10. Two Circadian Clocks In The Same Plant Tissue, ScienceDaily Next Article Bookmark and Share

    Excerpts: Dartmouth researchers have found evidence of two circadian clocks working within the same tissue of the plant Arabidopsis thaliana, a flowering plant often used in genetic studies. Their results suggest that plants can integrate information from at least two environmental signals, light and temperature, which is important in order to respond to seasonal changes. "The plant can then process the data and make decisions about flowering, which is a very critical decision. Early spring is cool, so it makes sense for a plant to clue in to more than one environmental signal."

  11. Innate Immunity: The Unsung Heroes, Nature Next Article Bookmark and Share

    Excerpts: The fact that innate immune mechanisms can terminate infections should not be surprising - invertebrates and jawless fish survive infections solely on the wits of their innate immune systems. (...). Given this potential, what proportion of infections is terminated by innate immunity? In modern human society, we seem to endure intense and relentless exposure to all manner of infectious agents. Perhaps the very fact that most people are not perpetually sick is testament to innate immunity squelching most of the infections that we contract.

  12. Structural Biology: Life's Transistors, Nature Next Article Bookmark and Share

    Excerpts: Voltage-gated ion channels control electrical activity in nerve, muscle and many other cell types. The crystal structure of a bacterial voltage-gated channel reveals the astonishingly simple design of its voltage sensor.

  13. Social Insects: Cuticular Hydrocarbons Inform Task Decisions, Nature Next Article Bookmark and Share

    Excerpts: Social insect colonies are organized without central control, and must not only accomplish many tasks, such as foraging and nest construction, but must also respond to changing conditions by adjusting the number of workers performing each task1, 2. Here we use chemically treated, artificial ants to show that cuticular hydrocarbons, which differ according to task, are used by workers of the red harvester ant (Pogonomyrmex barbatus) to recognize the tasks of the ants that they encounter. Encounters with other ants thus inform a worker's decision on whether to perform a particular task.

  14. A New Perspective On The Tracking Control Of Non Linear Systems, Alphagalileo & Proc. A Next Article Bookmark and Share

    Abstract: The problem of controlling complex, nonlinear structural and mechanical systems, such as robotic arms or satellites flying in tight formation, to move exactly along predefined trajectories is of great industrial and practical importance. This paper provides a new and simple, yet powerful and exact, solution to this long-standing problem. It draws its inspiration from the way Nature seems to control complex mechanical systems when their motions are constrained to follow certain trajectories. The results provided appear to be the simplest and perhaps most comprehensive available to date on controlling the motion of complex nonlinear systems along predefined trajectories (...).

  15. Hearing Colors, Tasting Shapes, Scientific American Next Article Bookmark and Share

    Excerpts: People with synesthesia--whose senses blend together--are providing valuable clues to understanding the organization and functions of the human brain. (...) If synesthesia were a genuine sensory effect, our subjects should easily see the triangle because for them, the numbers would look colored. When we conducted pop-out tests with volunteers, the answer was crystal clear. Unlike normal subjects, synesthetes correctly reported the shape formed by groups of numbers up to 90 percent of the time (exactly as nonsynesthetes do when the numbers actually have different colors).

    1. Experts See Mind's Voices in New Light, Nature Next Article Bookmark and Share

      Excerpts: Auditory hallucinations are a hallmark of schizophrenia: 50 percent to 75 percent of the 2.8 million Americans who suffer from the illness hear voices that are not there.(...) The research has led to new theories of what may cause such bizarre alterations in perception and has spawned at least one promising new treatment: the delivery of low-frequency magnetic pulses to areas identified by the brain scans seems to quiet, at least temporarily, the voices of patients who have not found relief through standard treatment with antipsychotic medications.

  16. Study Assesses Risks, Benefits Of Eliminating Monthly Menstruation, Penn State Live Next Article Bookmark and Share

    Excerpts: Given a choice, many women would probably opt out of the monthly cramping, bloating, bleeding and general discomfort that accompanies menstruation. A study under way at Hershey Medical Center is investigating whether a variation on the traditional oral contraceptive pill can prevent periods easily, safely and effectively. "Menstrual bleeding may be medically unnecessary and can cause undesirable symptoms such as cramping, headaches and mood swings," Legro said. "Not only is menstrual bleeding often an inconvenience, but it also can be a serious quality of life concern for many women."

  17. Fluctuations, Noise And Scaling In The Cardio-Pulmonary System, Fluct. & Noise Lett. Next Article Bookmark and Share

    Abstract: The structure and the functioning of cardio-pulmonary system is complex (...). In this review, we examine scaling in cardio-pulmonary physiology. The focus will be on the interpretation of scaling behaviors and their relation to structure-function in the normal and diseased cardio-pulmonary system. First, we overview fluctuations and scaling in respiratory rate variability in terms of a neural network model. Next, we analyze fluctuations in human heartbeat dynamics under healthy and pathologic conditions using wavelets and multifractal approaches. Finally, we show how the network failure of lung tissue structure leads to emphysema, a leading cause of respiratory disability and death worldwide.

    1. Fractal Changes In Heart Rate Dynamics With Aging And Heart Failure, Fluct. & Noise Lett. Next Article Bookmark and Share

      Abstract: In this work we analyze interbeat cardiac time series arising of three groups: healthy young and healthy elderly subjects and patients with congestive heart failure. (...) fractal organization is different for each group. In the case of healthy young subjects only one value of the fractal dimension is necessary to fit the interbeat data, whereas in the cases of healthy elderly and patients with congestive heart failure a crossover behavior in the fractal dimension is present but in opposite directions. By means of a "zoom" on the hinges of the crossover point interesting effects of aging are presented.

  18. U.S. Overhauls Administration to Govern Iraq, NYTimes Next Article Bookmark and Share

    Excerpts: The dramatic overhaul is part of a move ordered by President Bush that began with the appointment last week of L. Paul Bremer III, a counterterrorism veteran at the State Department, as the new top administrator in charge of rebuilding Iraq.(...) In Washington as in Iraq, General Garner came under heavy criticism for being almost invisible to ordinary Iraqis. (...) One possibility is that the Office of Humanitarian and Reconstruction Assistance would move outside the heavily walled Republican Palace and into a place that is less regal, one official said.

    1. Agencies Still Fail to Share Information, Reports Say, NYTimes Next Article Bookmark and Share

      Excerpts: New reports by GAO [General Accounting Office, Ed.] and police association charge that federal agencies are still not sharing key information about terrorist suspects because of interagency cultural differences and technology lags; Sen Charles Grassley says he is dismayed at lapses so long after Sept 11 terrorist attacks (M) Nearly 20 months after the Sept. 11 attacks, many federal agencies are still failing to share critical information about terrorist suspects with other agencies because of both cultural and technological barriers, officials said today.

    2. How to Get Syria Out of the Terrorism Business, NYTimes Next Article Bookmark and Share

      Excerpts: Getting Syria out of the terrorism business through diplomatic engagement would be a major achievement in itself, both for our counterterrorism campaign and our Middle East policy. (...), success with Syria could establish hard-nosed engagement as the most effective way to confront, and eventually to change, the behavior of states that back terrorism. In this regard, Secretary Powell's journey to Damascus could mark a new stage of the war on terrorism-one that will enable the Bush administration to match its military achievements with even more impressive diplomatic accomplishments.

    3. Senate Deal Kills Effort to Extend Antiterror Act, NYTimes Next Article Bookmark and Share

      Excerpts: The day's developments represented a major test of the balancing act between fighting terrorism and protecting civil liberties, and the result delivered a mixed verdict as many lawmakers expressed reservations about giving law enforcement officials too much power to fight terrorism. (...) masked intense behind-the-scenes maneuverings in recent weeks over the powers that the federal government has been given to fight terrorism.(...) Many Democrats have complained in recent months that the Justice Department has kept them in the dark about its counterterrorism activities since the Sept. 11, 2001, attacks.

    4. The Impossible Task for America's Spies, NYTimes Next Article Bookmark and Share

      Excerpts: The Bush administration's doctrine of pre-emption presumes that American intelligence can ferret out the most secret of foreign science with near infallibility.

    5. Genomics: Relative Pathogenic Values, NYTimes Next Article Bookmark and Share

      Excerpts: The bacterium that causes anthrax has several close relatives. Comparison of their genome sequences should provide insight into the biology of these organisms as agents of disease - and of terrorism.
