New Complexity Digest Milestones Reached

Complexity Digest remains dedicated to improving the network
information of the community of complex systems researchers and
practitioners. ComDig is now in its sixth year, we have over 5k email
subscribers and some10k or so who see our issues from radiation on
comdig.com and other sites and a dedicated global editorial and
software team. You may have seen our editors at a conference or two
with a video camera in hand capturing speakers for video abstracts
adding a sense of presence to the items we read.

Otherwise the team is transparent by choice so the content will carry
the message that complexity is solving problems. We are entirely
virtual....we meet once every two years but otherwise in constant
contact electronically. A standard method and quality is demanded by
Gottfried Mayer (Taiwan) as editor in chief. At his side in Taiwan is
Stella who formats the letter and manages the data base. The editorial
staff is Pritha and Atin Das, India, Nadia and Carlos Gershenson in
Belgium. Software, including the new format you see today, has been
developed by Matus Marko, Andrej Probst, and Lubos Kmetko, Slovakia.

You may note an increase in archiving capability including videos
thanks to the webserver space kindly provided by the Centrum Leo
Apostel of the Vrije Universiteit Brussel. Daily webmaster chores are
done by Steve Gage (US). And various financial and administrative
function are done by Elaine Gilpin (US) and Marilyn Pitchford (US).

I am proud of what we have accomplished.

    Excerpts:
    Change Makers. Foundry workers fill a mold after revising their operation to meet standards developed in a simulation exercise. E. Chamberlain
    Over the past decade, staff members at nearly 30 firms of various sizes have negotiated simulated enterprises devised by DiBello, who is affiliated with the City University of New York, and her coworkers. Participants routinely begin as vocal skeptics of the approach and end up using the experience as a framework to revitalize their workplaces. In the three-firm project, the "financial benefits [of the simulation exercises] were shockingly great for each company," DiBello says. "We think we're tapping into basic principles of cognitive acceleration and learning."
  2. The Adaptive Markets Hypothesis: Market Efficiency From An Evolutionary Perspective, Journal of Portfolio Management 30 Next Article Bookmark and Share

    Excerpts: One of the most influential ideas in the past 30 years of the Journal of Portfolio Management is the Efficient Markets Hypothesis, the idea that market prices incorporate all information rationally and instantaneously. However, the emerging discipline of behavioral economics and finance has challenged this hypothesis, arguing that markets are not rational, but are driven by fear and greed instead. Recent research in the cognitive neurosciences suggests that these two perspectives are opposite sides of the same coin. In this article I propose a new framework that reconciles market efficiency with behavioral alternatives by applying the principles of evolution---competition, adaptation, and natural selection---to financial interactions.
  3. Systems Biology and New Technologies Enable Predictive and Preventative Medicine, Science Next Article Bookmark and Share

    Excerpts: Systems approaches to disease are grounded in the idea that disease-perturbed protein and gene regulatory networks differ from their normal counterparts; we have been pursuing the possibility that these differences may be reflected by multiparameter measurements of the blood. Such concepts are transforming current diagnostic and therapeutic approaches to medicine and, together with new technologies, will enable a predictive and preventive medicine that will lead to personalized medicine.

    Biological information is divided into the digital information of the genome and the environmental cues that arise outside the genome.

    1. All Bio Systems Are Go, Wired Next Article Bookmark and Share

      Excerpts: The next advances in biology may rely on networked systems research, but will have little to do with computers (...).

      Instead, (...), techniques used to analyze interconnected systems will provide a better understanding of the most complex network of all: the human body.

      That's the ambition of scientists in systems biology, a burgeoning field which aims to understand the workings of the nuts and bolts of living organisms through the interactions of the thousands of pieces of DNA, RNA and proteins that network together in each cell of our body.

    2. Systems Biology And The Molecular Circuits Of Cancer, ChemBioChem Next Article Bookmark and Share

      Excerpt: Proliferative disorders are a major challenge for human health. The understanding of the organization of cell-cycle events is of the utmost importance to devise effective therapeutic strategies for cancer. The awareness that cells and organisms are complex, modular, hierarchical systems and the availability of genome-wide gene expression and protein analyses, should make it feasible to elucidate human diseases in terms of dysfunctions of molecular systems. Here we review evidence in support of a systems model of the cell cycle, in which two sequential growth-sensitive thresholds control entry into S-phase. The putative molecular determinants that set the threshold for entry into S-phase (...).
    3. Preliminary Studies On The In Silico Evolution Of Biochemical Networks, ChemBioChem Next Article Bookmark and Share

      Excerpts: Due to the variety and importance of roles performed by signalling networks, understanding their function and evolution is of great interest. Signalling networks allow organisms to process and react to changes in their internal and external environment. (...) two to three percent of all genomes code for proteins involved in signalling networks. The study of signalling networks is hindered by the complexities of the networks and difficulties in ascribing function to form. For example, a very complex dense network might comprise eighty or more densely connected proteins. In the majority of cases there is very little understanding of how these networks process signals. (...)
    4. Computational Design Of Reduced Metabolic Networks, ChemBioChem Next Article Bookmark and Share

      Excerpt: Cellular functions are based on thousands of chemical reactions and transport processes, most of them being catalysed and regulated by specific proteins. Systematic gene knockouts have provided evidence that this complex reaction network possesses considerable redundancy, that is, alternative routes exist along which signals and metabolic fluxes may be directed to accomplish an identical output behaviour. This property is of particular importance in cases where parts of the reaction network are transiently or permanently impaired, for example, due to an infection or genetic alterations. Here we present a computational concept to determine enzyme-reduced metabolic networks (...).
  4. Mice Do Fine Without 'Junk DNA', Nature News Next Article Bookmark and Share

    Excerpts:
    Mice seemed normal even when 3% of their genome had been deleted. c Getty
    Deleting non-coding regions from the genome has no apparent effect. (...) deleting large sections of non-coding DNA from mice appears not to affect their development, longevity or reproduction. The team created mice with more than a million base pairs of non-coding DNA missing - equivalent to about 1% of their genome. The animals' organs looked perfectly normal. (...) The group has now created mice missing three million base pairs. (...) "Survival in the laboratory for a generation or two is not the same as successful competition in the wild for millions of years," he argues.
    1. Puffed-Up Genome, Science Now Next Article Bookmark and Share

      Excerpts:
      Seeing double. The genome of the tiny puffer fish reveals that its ancestors duplicated their genome sometime after diverging from the lineage of humans and other vertebrates. Credit: Oliver Jaillon
      A newly published draft sequence of a puffer fish genome suggests that the vertebrate ancestor shared by bony fishes and humans had just 12 pairs of chromosomes, but the fishes doubled up after their lineage split from our own. (...)

      The spotted green puffer fish Tetraodon nigroviridis is one of about 20,000 kinds of ray-finned fishes, (...). About 450 million years ago, the ancestor of ray-finned fishes went on its own evolutionary tangent, splitting off from the vertebrate lineage that includes lobe-finned fishes, frogs, chickens, and humans.

  5. Solving Gene Expression, Science Next Article Bookmark and Share

    Excerpts: Words are static images on a page unless you know what they mean, how their meanings change depending on the context, and what the rules are for using them. Similarly, a complex regulatory code is buried within the genome, and researchers will need to decipher it to understand how genes are expressed, what their functions are, and how normal instructions are altered in disease.(...)

    As we begin to understand biological systems through carefully designed experiments and analyses, the complexity we are seeing now may begin to resolve into simpler principles.

    1. Gene Order and Dynamic Domains, Science Next Article Bookmark and Share

      Excerpts: When considering the daunting complexity of eukaryotic genomes, some comfort can be found in the fact that the human genome may contain only 30,000 to 40,000 genes. Moreover, growing evidence suggests that genomes may be organized in such a way as to take advantage of space. A gene's location in the linear DNA sequence and its position in the three-dimensional nucleus can both be important in its regulation. (...) paragon of simplicity, may still have a few things to teach us with respect to these facets of nonrandom genomes.
    2. Searching for the Genome's Second Code, Science Next Article Bookmark and Share

      Excerpts: The genome has more than one code for specifying life. The hunt for the various types of noncoding DNA that control gene expression is heating up.

      (...) it's going to take molecular cryptographers to crack its complex code. (...) The same genes have turned up in organisms as different as, say, mice and jellyfish. Instead, new findings from a variety of researchers have made clear that it's the genome's exquisite control of each gene's activity--and not the genes per se--that matters most.

    3. A Fast and Furious Hunt for Gene Regulators, Science Next Article Bookmark and Share

      Excerpts: Genes may be essential, but researchers increasingly recognize the pivotal role that another element of the genome--regulatory DNA--plays in human disease, speciation, and evolution. In many labs, the search to find where these regions are buried is intensifying. (...) others are experimenting with high-speed methods to detect regulatory regions, such as enhancers, en masse and determine what each one does.

      (...) Compare two or more sequenced genomes to identify those places where DNA outside genes is highly similar and presumably functional.

  6. Obtaining Multiple Separate Food Sources: Behavioural Intelligence In The Physarum Plasmodium, Alphagalileo & Proc. B Next Article Bookmark and Share

    Abstract: In order to evaluate an amoeba's performance in a complex survival task, we studied the morphology of the Physarum plasmodium transportation network when presented with multiple separate food sources. The plasmodium comprises a network of tubular elements through which chemical nutrient, intracellular signals and the viscous body are transported and circulated. We report the evidence that the tube network is reformed as well-designed with short total length and fault tolerance, in response to locations of food sources. This implies that this unicellular organism has high computational ability to solve some optimization problem, difficult even for human.
    1. Interactivity, Dynamic Symbol Processing, And The Emergence Of Content In Human Communication, The Info. Soc. Next Article Bookmark and Share

      Excerpt: A major step in resolving conceptual ambiguity surrounding interactivity involves making a distinction between micro-level psychological processes and the macro-level societal effects that emerge from them. The proposition cuts against the epistemological grain of social sciences, such as psychology and sociology (...). The position advanced here suggests theories where processes operate at one level and generate effects that emerge at a higher level. Further, it is argued that the best place to begin looking at the process of interaction is at the level of the neural circuit, a realm far below discussions that center at the interpersonal or cultural levels.
  7. Palaeontology: Leg Feathers In An Early Cretaceous Bird, Nature Next Article Bookmark and Share

    Excerpts: Here we describe a fossil of an enantiornithine bird from the Early Cretaceous period in China that has substantial plumage feathers attached to its upper leg (tibiotarsus). The discovery could be important in view of the relative length and aerodynamic features of these leg feathers compared with those of the small 'four-winged' gliding dinosaur Microraptor and of the earliest known bird, Archaeopteryx. They may be remnants of earlier long, aerodynamic leg feathers, in keeping with the hypothesis that birds went through a four-winged stage during the evolution of flight.

      Excerpts: (...) creating a silicon chip implant that mimics the hippocampus, an area of the brain known for creating memories. If successful, the artificial brain prosthesis could replace its biological counterpart, enabling people who suffer from memory disorders to regain the ability to store new memories.

      And it's no longer a question of "if" but "when." The six teams involved in the multi-laboratory effort, including USC, the University of Kentucky and Wake Forest University, have been working together on different components of the neural prosthetic for nearly a decade.

    2. Auras May Be Generated In The Brain, Nature News Next Article Bookmark and Share

      Excerpts:
      Synaesthesia can cause people to see coloured auras around friends or loved ones. c Punchstock
      Synaesthesia most probably comes from a cross-wiring in the brain. Psychologist Simon Baron-Cohen of the University of Cambridge, UK, has suggested that it comes about when the densely connected infant brain does not prune itself rigorously enough as it grows. Ward suggests that the cross-wired areas in this case are the retrosplenial cortex, which is associated with emotion, and the V4 area, which has been shown to be involved in colour perception. The two areas are close together in the brain.
  9. Can Computers Untangle the Neural Net?, The Scientist Next Article Bookmark and Share

    Excerpts: Computational neuroscientists are not to be confused with scientists who treat the brain as a biological blueprint for computer prototypes (...) For the computational neuroscientist, the computer is not a goal, but a tool to create predictive models constrained by biology.

    (...) The result of such thinking is a field in which dozens of labs work to blend data and theory into working models of the brain, or at least of small areas of the brains of everything from leeches to humans.

    1. On The Trail Of An Odor Map - Nobel Winning Work Has A Way To Go, The Scientist Next Article Bookmark and Share

      Excerpt: A smell can conjure intimate memories and even change behaviors. Scent is primal, so closely related to territoriality, predation, food, and sex in many animals, yet to most humans it seems an accessory, like a dab of perfume. People devote much more conscious attention to vision and taste, which have three and five receptor types, respectively. The human genome, however, has 350 intact odorant receptor genes, and other mammals have many times that amount suggesting that olfaction plays a more profound role.
  10. Malaria: A Complex New Vaccine Shows Promise, Science Next Article Bookmark and Share

    Excerpts: It uses several techniques to boost the immune system's fight against the malaria parasite. Its designers engineered a hybrid protein that combines a protein fragment from the parasite, Plasmodium falciparum, with a piece of a protein from the hepatitis B virus. (...) The hepatitis B protein is included because it is particularly effective at prompting an immune response. The vaccine also contains a powerful new adjuvant, developed by GSK Biologicals, that increases the body's production of antibodies and T cells.
    1. Antibiotics: A Shot In The Arm, Nature Next Article Bookmark and Share

      Excerpts: But just as we need them most, the antimicrobial drug pipeline is running dry. Until ten years ago, all major drug companies ran antibacterial research programmes. Today, these programmes have been drastically pruned, and many have been cut altogether as companies pursue more lucrative areas, such as chronic illnesses and mood disorders.

      This all makes for a potential healthcare calamity. Although the number of hospital-acquired infections has been gradually declining in the United States, a greater proportion of them - now about 70% - are resistant to at least one antibiotic.
      Editor's Note: This looks like the flu vaccine debacle was only the tip of an ice-berg.

    Experts: Only a current composed of entangled electrons in the superconductor can achieve this [Meissner, Ed.] effect, Vedral says. The current halts the photons of the magnetic field after they have travelled only a short distance through the superconductor. For the normally massless photons it is as if they have suddenly entered treacle, effectively giving them a mass.

    Vedral also claims that a similar mechanism may be behind the mass of all particles. (...) various forces in the universe, (...), act through ¡§mediator¡¨ particles such as the gluon.

    1. Bridging Light and Matter, Science Now Next Article Bookmark and Share

      Excerpts: (...) reliably transfer quantum information from matter to light. The procedure may soon enable scientists to exploit the advantages of both matter and light in building systems for quantum communications.

      Quantum bits stored on particles of light travel well--they can zip for kilometers down a fiber-optic cable--but they are tricky to store. Quantum bits stored on matter "keep" for milliseconds or longer, but they're usually confined to a trap and can't be transmitted from place to place. Now scientists have found a way to bridge the two.

    2. Researchers Build Quantum Info Bank By Writing on the Clouds, Science Next Article Bookmark and Share

      Excerpts: (...) describe how they store a quantum bit in a cloud of rubidium atoms and induce the cloud to inscribe that information, undamaged, upon a photon. The researchers start with two clouds of rubidium gas. By shooting a laser through both clouds simultaneously, they force the clouds to emit a single photon that is quantum-mechanically entangled with both of the clouds simultaneously. (...) The entanglement links the fates of the photon and the clouds; tweaking the photon's polarization alters the quantum state of the clouds.

    The source of fake cash can now be spotted
    That staple of crime novels - solving a case by identifying the typewriter used to write a ransom note - is being updated for the modern day.

    US scientists have discovered that every desktop printer has a signature style that it invisibly leaves on all the documents it produces.

    They have now found a way to use this to identify individual laser printers.

    The work will help track down printers used to make bogus bank notes, fake passports and other important papers.

    Excerpt: The collisions that spawn planets are bigger and take place over longer periods of time than previously thought, say astronomers who studied nearly 300 stars with NASA's Spitzer Space Telescope. The new cache of data gives astronomers fresh hope that Earth-like planets might be common in the universe.

    Planets are thought to grow as dust collides and sometimes sticks together in the discs around young stars. Until now, most theorists suspected the process was relatively smooth, with dust clumps building up gradually through successive collisions.

"We think it guarantees that we'll have the kind of treatment of these individuals that we believe they deserve," said Vice President Dick Cheney, who was a driving force behind the policy.

    3. Memo Lets CIA Take Detainees Out of Iraq, Washington Post Next Article Bookmark and Share

      Excerpts: At the request of the CIA, the Justice Department drafted a confidential memo that authorizes the agency to transfer detainees out of Iraq for interrogation -- a practice that international legal specialists say contravenes the Geneva Conventions.

      Experts:
      A 1996 photograph of a bunker where high-density explosives were stored at Al Qaqaa, an Iraqi military facility south of Baghdad.
      The International Atomic Energy Agency publicly warned about the danger of these explosives before the war, and after the invasion it specifically told United States officials about the need to keep the explosives secured, European diplomats said in interviews last week. Administration officials say they cannot explain why the explosives were not safeguarded, beyond the fact that the occupation force was overwhelmed by the amount of munitions they found throughout the country.

      Excerpts: Q. Aren't there caches of these kinds of explosives throughout the country? Why all the fuss about this particular site?

      A. Al-Qaqaa was considered the pre-eminent site in Iraq for high explosive stockpiles. When Iraq declared the HMX, RDX and PETN after the 1991 Gulf War, nuclear agency experts concentrated the high explosives at Al-Qaqaa so they could be monitored, according to a nuclear agency official. However, U.S. troops on the ground found high explosives throughout the country.
