Excerpts: Adaptive Enterprise
What is it? It is business and IT synchronized to capitalize on change, allowing companies to execute business decisions more quickly, broadly and easily than ever before. The Adaptive Enterprise follows a few key design principles: simplify, standardize, modularize and integrate
Simplify: Reduce the number of IT elements in your network. Eliminate customization. Automate change. Simplify everything and you are prepared for anything.
Integrate: Build a dynamic link between business and IT. Connect applications and processes inside and out. Watch everything work together. And see change coming a mile away.

Abstract: For many years, research and management thinking has focused on understanding business relationships and networks. Now, the focus is shifting to managing business relationships and networks. This new approach focus poses two questions. Since networks are loosely coupled systems, to what extent are business networks manageable? Furthermore, how can a firm's ability to manage a network be characterized and measured? This paper addresses these two questions by synthesizing the current state of knowledge on management issues in networks and the contribution to managerial abilities in complex relationships. The discussion leads to a set of propositions describing the abilities firms will need to successfully manage complex business networks.

|
There has been no new ball game until the later part of the 20th century, Wall Street communities began to utilize Neural Networks, Fuzzy Logic or Chaos Theory with modern computers in searching for ultimate solutions but nothing significant has been achieved either.
To solve the discrepancy of traditional analysis, ATMOL has overthrown the fixed time interval and brings in a notion known as the kinetic equilibrium. Accordingly, J-Chart is able to avoid Random-Walk's effects. Furthermore, J- Chart utilizes the Pair Production Phenomenon of Quantum Physics as backbone (...).
Intelligent Advertising, AI & Society
Abstract: Digital media is getting smarter. Home electrical goods are getting smarter. This article explores how one aspect of content is beginning to reflect this-digital advertising. It is becoming increasingly important for advertisers to target consumers as individuals and in communities of interest rather than by demographic. This article explores the impact of smart systems and artificial intelligence (AI) on advertising and examines different approaches to creating intelligent and smart content and how behaviour is fast becoming the guiding principle for new content forms.

Noise Management: Sound And Vision, Nature
Excerpts: Computer simulations that paint Europe's cities in riotous color are at the core of a bold plan to restore peace and quiet to a population driven to distraction by traffic noise.
I'm swooping down the boulevards of Paris in a virtual simulation of the city of light, where sound levels are depicted as color. The deep blue roar of traffic washes along the streets, blazing crimson against the base of adjacent buildings, (...) I'm exploring one of the world's first three-dimensional (3D) computer maps of urban decibels —(...).
Competition-Induced Preferential Attachment, arXiv
Abstract: Models based on preferential attachment have had much success in reproducing the power law degree distributions which seem ubiquitous in both natural and engineered systems. Here, rather than assuming preferential attachment, we give an explanation of how it can arise from a more basic underlying mechanism of competition between opposing forces.
We introduce a family of one-dimensional geometric growth models, constructed iteratively by locally optimizing the tradeoffs between two competing metrics. This family admits an equivalent description as a graph process with no reference to the underlying geometry. Moreover, the resulting graph process is shown to be preferential attachment with an upper cutoff. We rigorously determine the degree distribution for the family of random graph models, showing that it obeys a power law up to a finite threshold and decays exponentially above this threshold.
We also introduce and rigorously analyze a generalized version of our graph process, with two natural parameters, one corresponding to the cutoff and the other a ``fertility'' parameter. Limiting cases of this process include the standard Barabasi-Albert preferential attachment model and the uniform attachment model. In the general case, we prove that the process has a power law degree distribution up to a cutoff, and establish monotonicity of the power as a function of the two parameters.
Intel Makes Light Work For Chips, BBC News
Excerpts:
Fast networks could get cheaper thanks to Intel
|
Silicon has become the material of choice for computer processors because it is cheap and because electrons move through it in ways that can be easily controlled and do useful work.
Now Intel researchers have found a way to do make silicon do almost the same thing with light at speeds almost 50 times faster than anyone has demonstrated before.
(...), Intel scientists Ansheng Liu and colleagues said they had built a silicon modulator that can send a billion pulses of light a second down fibre-optic cables.
Living Machines, Wired
Excerpts: Technology and biology are converging fast. The result will transform everything from engineering to art - and redefine life as we know it.(...)
The notion that the inorganic world is alive is as old as mythology; think of Poseidon, the Greek personification of the sea. However, the tools available to examine life at its most essential - DNA sequencing, bioinformatics, gene chips - are new. (...) It turns out that many of life's properties - emergence, self-organization, reproduction, coevolution - show up in systems generally regarded as nonliving.

Slaves To Rhythm - Oscillations, Cycling And The Pace Of Life, The Biochemist
Abstract: Plants are generally rooted to the spot and have to make the best advantage of the limited availability of sunlight, their most important resource. Not surprisingly, many aspects of plant physiology and development are organised by an internal chronometer. This so-called "circadian" clock imposes a 24-hour rhythm on molecular, biochemical and physiological processes in tune with the environmental light-dark cycle.
Central And Peripheral Oscillators In Mammals - A Guided Tour Through A Network Of Clocks, The Biochemist
Abstract: For decades, the circadian system of animals was viewed as a single or a few centralized structures driving all overt physiological circadian rhythms. Recent data have questioned this view and have revealed a much more complex and dynamic picture. We now know that circadian oscillators are also present in many different tissues and constitute part of a hierarchical circadian system. Here we describe this multi oscillator system that constitutes the basis for the variety of physiological rhythms.
Photosynthesis Inspires Molecular-Assembly Process, EE Times
Excerpts: Nanotechnologists have recently succeeded in building molecular systems based on highly efficient versions of the molecular "machine" that plants use to turn sunlight into energy.
For example, Sandia National Laboratory has developed a chemical system that creates a wide variety of complex nanostructures from platinum. The system uses the porphyrin molecule, a protein essential to photosynthesis, as a catalyst for depositing platinum on small organic structures called lipids. It could lead to a light-driven source of hydrogen.

Life's Patterns: No Need to Spell It Out?, Science
Excerpts: Yet genes alone can't specify the shape and arrangement of all an organism's parts, says Jacques Dumais, a biologist at Harvard University in Cambridge, Massachusetts. "There is not enough information in the DNA to code for that," Dumais says. "As soon as you talk about something more complicated than a virus, you can't do it."
Instead, the patterns of life must arise without detailed blueprints, just as an exquisitely symmetrical snowflake emerges from the random collisions of water molecules in moist air.
A surprising resistance would be put up by sand grains hiding a buried treasure chest.
Evolutionary Dynamics of Biological Games, Science
Abstract: Darwinian dynamics based on mutation and selection form the core of mathematical models for adaptation and coevolution of biological populations. The evolutionary outcome is often not a fitness-maximizing equilibrium but can include oscillations and chaos. For studying frequency-dependent selection, game-theoretic arguments are more appropriate than optimization algorithms. Replicator and adaptive dynamics describe short- and long-term evolution in phenotype space and have found applications ranging from animal behavior and ecology to speciation, macroevolution, and human language. Evolutionary game theory is an essential component of a mathematical and computational approach to biology.
Turning Points Prisoners Of The Dilemma, Nature
Excerpts: my thinking or approach to science has changed course. Far from a linear path, my scientific career feels more like brownian motion, which is continuous everywhere, but differentiable nowhere. There have been many turning points that have sent me off in new directions, making me forget what I had been doing at the time.
I am no longer embarrassed to work on games. They are the generic description of evolutionary interactions among genes, cells and people. Children love games. Scientific creativity is to never stop playing.
Making Sense of a Heart Gone Wild, Science
Excerpts: For implantable cardioverter defibrillators (ICDs), the success rate exceeds 99%. (External defibrillators, like the one used by the rescue squad, have a lower success rate, primarily because they are not always applied in time.) It's a true medical miracle--and as befits a miracle, no one can explain why it works. "We don't even know how the electric current goes into the heart," says Gray. Nor does anyone really know how ventricular fibrillation gets started, or why a big shock brings it to an end.
Introductory Science and Mathematics Education for 21st-Century Biologists, Science
Excerpts: Galileo wrote that "the book of nature is written in the language of mathematics"; his quantitative approach to understanding the natural world arguably marks the beginning of modern science. Nearly 400 years later, the fragmented teaching of science in our universities still leaves biology outside the quantitative and mathematical culture (...). This strikes us as particularly inopportune at a time when opportunities for quantitative thinking about biological systems are exploding. We propose that a way out of this dilemma is a unified introductory science curriculum
Inferring Cellular Networks Using Probabilistic Graphical Models, Science
Abstract: High-throughput genome-wide molecular assays, which probe cellular networks from different perspectives, have become central to molecular biology. Probabilistic graphical models are useful for extracting meaningful biological insights from the resulting data sets. These models provide a concise representation of complex cellular networks by composing simpler submodels. Procedures based on well-understood principles for inferring such models from data facilitate a model-based methodology for analysis and discovery. This methodology and its capabilities are illustrated by several recent applications to gene expression data.
The Brain's Word Act: Reading Verbs Revs Up Motor Cortex Areas, Science News
Excerpts: For more than 60 years, scientists have known that a strip of neural tissue that runs ear-to-ear along the brain's surface orchestrates most voluntary movement, from raising a fork to kicking a ball. A new brain-imaging study has revealed that parts of this so-called motor cortex also respond vigorously as people do nothing more than silently read words.
Not just any words get those neurons going, however. They have to be action words-active verbs.
(...) such as lick, pick, or kick-the motor cortex areas that control the specified action exhibit high rates of blood flow,(...)
Ion Channels: Shake, Rattle Or Roll?, Nature
Excerpts: Nerve transmission depends on voltage-gated ion-channel proteins, which in turn depend on the behaviour of a membrane domain called the voltage sensor. Therein lies the latest episode in a continuing story.
The propagation of electrical signals in the nervous system endows animals with moment-to-moment overall coherence. Without it, worms could not wriggle, flies could not find fruit, and we could not read News and Views. Electrical impulses coursing down the nerve axon arise from a molecular minuet in which ion-channel proteins deliver charged particles, Na+ and K+, across the nerve membrane.
Soul Made Flesh Today On Fresh Air, NPR Audio
Excerpts: Health and Science writer Carl Zimmer's new book is Soul Made Flesh: The Discovery of the Brain-and How it Changed the World. It's about Thomas Willis, the scientist whose research on the workings of the brain during the 17th century became the basis of modern neurology.

Guggenheim Fellow and received the Pan-American Health Organization Award for Excellence in International Health Reporting.
MIT Team Discovers Memory Mechanism, ScienceDaily
Excerpts: MIT neuroscientists have discovered a new brain mechanism controlling the formation of lasting memories. This mechanism explains how signals between neurons stimulate production of the protein building blocks needed for long-term memory storage. Long-lasting memories are stored in the brain through strengthening of the connections, or synapses, between neurons. Researchers have known for many years that neurons must turn on the synthesis of new proteins for long-term memory storage and synaptic strengthening to occur (...). "What we have discovered (...) is that there is a direct activational signal from the synapse to the protein synthesis machinery,"
Cloned Human Embryos Yield Stem Cells, Nature

The team used DNA from cumulus cells - a specialized type of cell that helps to nourish developing eggs. This genetic material was injected into 242 empty eggs taken from 16 women, yielding a total of 30 embryos.
In theory, such embryos could develop into human clones (...) But human cloning is illegal in many countries, and Hwang's team was only interested in using these very early embryos for therapeutic treatments. The embryos were allowed to divide in culture for just 5 to 6 days before being terminated.

Researchers may have discovered how pigeons find their way along familiar routes. Instead of heading straight for their destination, they follow main roads, railways and rivers. (...)
Some of the birds that used landmarks did so again and again on separate occasions, says Guilford, following a set path to theirloft. "One pigeon flies along the road to the first roundabout, takes the third exit, goes along the dual carriageway to the next roundabout, then leaves the road and goes cross-country," he says.

If you still think the emphasis on water chemistry is overblown, confront the chamber of horrors on display in the lobby of GE Infrastructure's main water-research lab (...). It holds a glassed-in graveyard of corroded pipes, split joints and other industrial casualties, all results of bad water flowing through manufacturing processes, cooling systems and the like.

Talking Simplicity, Building a Maze, NY Times
Excerpts: For decades, Congress has used the tax code to engineer social goals and hand out favors, a trend that accelerated during the Clinton administration and became supercharged during the administration of George W. Bush, which has introduced vast changes in such rapid-fire order that not all the consequences are understood even by people who study tax policy. Three major tax bills enacted in three years have vastly complicated the tax code, and a fourth Bush tax-cut bill is in the works.
Four Ways That Conventional Wisdom Can Go Astray, NY Times
Excerpts: The I.R.S.'s pamphlets, like the one for business use of your home, are widely considered to be accurate statements of the law, or, if there is any doubt about interpretation, of the I.R.S. position on the law. But the information people get at the agency's walk-in advice centers does not have nearly such a good reputation.

Halliburton Accused of Wasting Tax Money, NYTimes
Excerpts: Halliburton, which supplies military support services in Iraq and elsewhere, routinely purchased items at higher prices from preferred suppliers, said Henry Bunting, who worked for the company in Kuwait last year.
``There were frequent instructions by procurement supervisors and management to keep ... requisitions under the $2,500 threshold to avoid competitive bidding,'' Bunting, of Houston, told the Senate Democratic Policy Committee.
``Remember, this is a 'cost plus contract' so Halliburton would get reimbursed for its costs plus a percentage,'' he said.
Editor's Note: Here it appears that the "fitness function" is an extreme example of a fitness function representing the rule "privatize profits by maximizing the costs to the taxpayer".
Halliburton Likely to Be a Campaign Issue This Fall, NY Times
Excerpts: While Bill Dal Col, a Republican consultant, called Halliburton "a good rallying cry" for Democrats that "will help with fund-raising," he added that "it doesn't really have any traction with anyone who is not already opposed to the administration."
(...) Pentagon comptroller, Dov S. Zakheim said in Congressional testimony last week that Halliburton was "doing their best to do the right thing."
In the advertisements, Dave Lesar, Halliburton's chief executive, said: "You've heard a lot about Halliburton lately. Criticism is O.K. We can take it. Criticism is not failure."

Abstract: (...) it has been assumed that being in a position to choose from more options is preferred to having fewer options. Combining a dictator game (a no-choice situation for the receiver) and an ultimatum game (the receiver can choose between two options) we investigated whether receivers prefer to have some freedom of choice (...) even in the presence of monetary incentives to choose otherwise. The experimental results show that a strong majority of players is not willing to give up the option to veto without monetary incentives to do so. The higher the monetary incentives the more players give up their veto power.

Book Announcement: The decade of the 1990s witnessed enormous changes in the international environment. And while globalization expanded opportunity, growth, and incomes, it increased inequality of incomes and decreased human security. Moreover, as countries have become more closely linked, insecurity in one country has affected security in other countries. This volume explores the complex challenges that globalization poses for human security. Many of the challenges described are already high on the agenda of the international community. By adding a human security dimension to their analysis, these authors provide new insight into attempts to reduce our vulnerability to the new forces unleashed by global changes.

Mid-East 'Democracy' Plan Raises Questions, BBC News Online
Excerpts:
Bush wants Iraq to mark the first step to Mid-East democracy

A plan by President Bush to make a ringing declaration about democracy in the Middle East at the G8 summit of industrialised nations in June is raising questions among some American allies.
They are concerned that it might sound as if the West is hectoring the Arab world and that other initiatives along the same lines from the United Nations and the European Union are being ignored.(...)
The American plan builds on the policies towards the development of democracy already laid out by President Bush.
How America Doesn't Vote, NYTimes
Excerpts: (...) people will show up to vote and find they have been wrongly taken off the rolls. The lists of eligible voters kept by localities around the country are the gateway to democracy, and they are also a national scandal. In 2000, the American public saw, in Katherine Harris's massive purge of eligible voters in Florida, how easy it is for registered voters to lose their rights by bureaucratic fiat. Missouri's voting-list problems received far less attention, but may have disenfranchised more eligible voters.
U.N. Envoy, Visiting Iraq, Backs Cleric on Elections, NY Times
Excerpts:
Lynsey Addario/Corbis, for The New York Times
A poster of Grand Ayatollah Ali al-Sistani hung above shoppers in Baghdad yesterday.

Mr. Brahimi, who is leading a United Nations team that arrived this week to assess the possibility of holding direct elections, did not say whether he thought elections could be held by May 31. That is the date by which the Bush administration hopes to put a transitional national assembly in place to appoint the new government.
Though the Bush administration has yet to acknowledge that security also poses a problem for elections, many experts say the country is too unstable to stage a fully democratic process.
Complex Challenges: Global Terrorist Networks
A Tale of Nuclear Proliferation: How Pakistani Built His Network, NYTimes
Excerpts: "First, he exploits a fragmented market and develops a quite advanced nuclear arsenal. Then he throws the switch, reverses the flow and figures out how to sell the whole kit, right down to the bomb designs, to some of the world's worst governments." (...)
Taken together, they show how Dr. Khan assembled a far-reaching organization of scientists, engineers and business executives who operated on murky boundaries between the legal and the illegal, sometimes underground but often in plain view, unencumbered by international agreements that prohibit trafficking in nuclear technology.
Cuba Detentions May Last Years, NY Times
Excerpts: A large portion of detainees at Guantánamo Bay, Cuba, could be held for many years, perhaps indefinitely.(...)
"We feel very much like we are in an active war," said the official, asserting that the civilian law enforcement model in which people are prosecuted for crimes or set free did not apply. "What we're doing at Guantánamo is more understandable in the war context," the official said.
(...) the Pentagon was more concerned with "the rights of the soldiers having these people not going back to the battlefield" (...).
Editor's Note: In a war, one country can surrender and thereby end the war. There is no such authority among the terrorist networks. Therefore the war claim of the US government can imply unchecked power without any temporal limitation as long as the government "feels" the war against terror is still going on.
