2. Neural Maps In Remote Sensing Image Analysis, Neural Networks
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 (¡K).

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.
Scale-Free Networks, Albert-Laszlo Barabasi, Eric Bonabeau, Scientific
American, 2003/05
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
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. (¡K) 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. The
researchers suggested several methods to deter the attacks they described.

4. Cellular Manufacturing Theory, strategy+business
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.

Excerpt: 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.

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 (¡K). 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 (¡K).

5. The Global-Brand Advantage, MIT Sloan Management Review
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
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
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. (¡K), Benjamin Lu and
colleagues describe a remarkably simple version of apoptosis in the ink-cap
mushroom Coprinus cinereus (¡K)
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.

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.
(¡K) have been looking closely at how the outer membranes of yeast cells
vibrate, depending on the condition of the cells.
(¡K) 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
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.
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
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
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. (¡K). 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.

13. Social Insects: Cuticular Hydrocarbons Inform Task Decisions, Nature
Excerpt: 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
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
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).
Hearing Colors, Tasting Shapes, Vilayanur S. Ramachandran, Edward M.
Hubbard, Scientific American, 2003/04/15
Excerpt: 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.(¡K)
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
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.
Abstract: The structure and the functioning of cardio-pulmonary system is
complex (¡K). 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.

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. (¡K) 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
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.

19. Complex Challenges: Global Terrorist Networks
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.

NYTimes, 2003/04/30
Excerpt: 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. (¡K), 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.

refraction.
Molecular Biology: Complicity Of Gene And Pseudogene, Jeannie T. Lee,
Nature 423, 26 - 28 (2003); doi:10.1038/423026a, 'Pseudogenes' are produced
from functional genes during evolution, and are thought to be simply
molecular fossils. The unexpected discovery of a biological function for
one pseudogene challenges that popular belief.
