Roma, Italy), Andrew Rogers (PhD student) and Alan Sokal (NYU, USA). Jensen, Guttmann, Rogers and associates have developed algorithms for the enumeration of self-avoiding walks (a model relevant to polymer science) on various lattices. They have significantly extended the series for the square, triangular and honeycomb lattices including series for metric properties such as the end-to-end distance and radius of gyration. In collaboration they undertook a careful and extensive study of the series (supplemented by Monte Carlo simulations) of the correction-to-scaling exponent of self-avoiding walks on two-dimensional lattices.

An irreducibly complex system cannot be produced gradually by slight, successive modifications of a precursor system, since any precursor to an irreducibly complex system is by definition nonfunctional." Michael Behe his essay is intended to back up some elements of Keith Robison's excellent FAQ detailing the shortcomings of Behe's arguments ( http://www.talkorigins.org/faqs/behe/review.html ). Another excellent rebuttal by H. Allen Orr can be found at http://bostonreview.net/br21.6/orr.html .

Futuyma, Richard Dawkins, Michael Behe, Phillip Johnson and David Berlinski among others. Many people on Talk.Origins (T.O.) and elsewhere have outlined the conceptual reasons why Darwinian evolution can produce irreducibly complex (IC) systems. I try here to present some evidence to back up these concepts. In Robison's

http://www.talkorigins.org/faqs/behe.html

Extractions: n 1996, the Free Press published a book by Lehigh University biochemist and intelligent design advocate Michael Behe called Darwin's Black Box: The Biochemical Challenge to Evolution . The book's central thesis is that many biological systems are "irreducibly complex" at the molecular level. Behe gives the following definition of irreducible complexity: By irreducibly complex I mean a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning. An irreducibly complex system cannot be produced directly (that is, by continuously improving the initial function, which continues to work by the same mechanism) by slight, successive modifications of a precursor system, because any precursor to an irreducibly complex system that is missing a part is by definition nonfunctional. An irreducibly complex biological system, if there is such a thing, would be a powerful challenge to Darwinian evolution. (p. 39)

Extractions: Complex Systems and Soft Materials The Complex Systems and Soft Materials Program is a collaborative effort between three research groups in Norway: The Complex Systems and Soft Materials Group at the University of Oslo, the Complex Systems and Soft Materials Group at the Norwegian University of Science and Technology (NTNU), and the Physics Department at the Institute for Energy Technology (IFE). Since January 2003 we have been awarded funds and status as a STRATEGIC UNIVERSITY PROGRAM (SUP) in Norway by the Norwegian Research Council (NFR). This grant is given based on a thorough evaluation of our work by a group of renowned international experts. The SUP grant is a formal recognition of the importance of our research to the international as well as to the Norwegian society. Our focus is the physics of soft condensed matter and collective phenomena in mesoscopic and macroscopic systems. An example of soft condensed matter is clay. It is soft, i.e. macroscopically non-crystalline, and it shows a fantastic richness in behavior under different conditions. Given that the world is full of clay, it is surprising how little is known about its physical properties. An example of a collective phenomenon in a macroscopic physical system is that of fracture: When a material is failing under stress, fractures develop due to the stress field. The stress field in turn develops due to the fractures. It becomes a bootstrap process, and this is the meaning of a collective phenomenon.

Extractions: admin area (restricted access) Welcome to COSNet - the ARC Complex Open Systems Research Network 'characterising and analysing complex systems for explanation, prediction and control' Complexity is the common frontier in the physical, biological and social sciences. This Network will link specialists in all three sciences through five generic conceptual and mathematical theme activities. It will promote research into how subsystems self-organise into new emergent structures when assembled into an open, non-equilibrium system. Outcomes will include new technologies and software tools and deeper understanding of fundamental questions in science. An essential function of the network will be introducing researchers and end users to new tools and broadening the horizons of graduate students. How did life emerge from primordial chaos? Can we tame a turbulent burning fusion plasma to power our civilisation in coming centuries? Can we design an economic system that works without cyclic booms and busts? These, and many others, are the kinds of big questions that complexity theory seeks to answer by providing the conceptual and mathematical tools to describe and model open systems with many interacting components. By preparing Australian researchers to move beyond the comfort zone of their own specialisations, to learn a language in which they can communicate, the Network will provide an integrative force that will foster new industries and lead to benefits in human health, national security, economic well-being and sustainability.

http://www.ccsr.uiuc.edu/

Extractions: The Center for Complex Systems Research (CCSR) studies systems that display adaptive, self-organizing behavior and systems that are usually characterized by a large throughput, such as turbulent flow, lightning, and the flow of information through the internet. To describe these complex systems, we develop models and techniques drawn from nonlinear dynamics and chaos, neural nets, cellular automata, artificial life, and genetic algorithms. Each year CCSR organizes and hosts the conference Understanding Complex Systems The Center for Complex Systems Research has a rich history. Founded in 1986 by Stephen Wolfram, the center was later led by Norman Packard and E. Atlee Jackson. A collection of technical reports and scientific publications of CCSR researchers ranging from cellular automata to entrainment control of chaos, experimental studies of turbulent flows, chaotic electronic circuits, and fractal agglomeration patterns is available. The research at CCSR is supported by the National Science Foundation Grant No. NSF PHY 01-40179, NSF DMS 03-25939 ITR, and NSF DGE 03-38215

Extractions: Fax: +49-421-218-9104 Our living world is made up of simple elementary forces and constitutents. But how do these work together to make life, evolution, brains, genomes, immune systems, societies? We study general principles of complex systems in nature from the perspective of statistical physics, often reducing a system to the most simple working model for a particular phenomenon. We use methods from statistical and computational physics, and our main tool, the computer, allows for the new kind of "experimental" theoretical physics. Research topics are interdisciplinary with current emphasis on: Complex networks, Theoretical biophysics, Self-organized criticality, Socio- and Econophysics.

http://graphics.stanford.edu/projects/rivet/

Extractions: Rivet is a general-purpose environment for the analysis and visualization of complex systems. Rivet is a powerful and flexible system, providing analysts with a single tool that can be learned once and applied to a wide range of problems. The underlying approach in the development of Rivet is to understand and analyze the visualization process itself: to identify the set of fundamental visualization components, or building blocks, and define their interfaces and relationships. Users can then develop sophisticated visualizations by writing scripts that create and connect these basic building blocks. This approach, and the resulting modular architecture, provides several significant advantages: Extensibility.

Links By Jason Rosenhouse Proponents of intelligent design (ID) assert that certain complex biological systems could not emerge from a gradual evolutionary process. They argue instead that such structures are best explained via the deliberate action of an unspecified intelligent designer. Few scientists endorse this conclusion, and they have good reasons for being skeptical. They understand that the prolonged action of natural selection can be expected to leave traces behind in the structure of modern organisms. And when scientists go looking for those traces they invariably find them in droves. Recall that natural selection operates by preserving small, favorable variations that occur naturally in any population of organisms. Over time these variations accumulate to the point that large-scale change is the result. This implies that natural selection works by modifying structures already present in the organism. It does not craft new, complex systems from scratch. This observation is crucial in distinguishing between those systems that could have been crafted by selection and those that could not have been. If we find that a particular organism possesses a complex system made from parts wholly distinct from anything to be found in the organisms closest evolutionary cousins, it will be difficult to explain that system via selection. But if we find that the system appears to be cobbled together from parts that were readily available, then natural selection remains a strong candidate.

It is making visible the ways in which we have woven the world together through technology. It is showing how both local and global systems are dependent and interdependent on the smooth functioning of computers. While we cannot predict which of these systems will fail, we do know that few nations or systems will remain unaffected. The unprecedented global scope of Y2K represents a new breed of systemic problems. When complex systems fail, prevailing models of leadership offer little help. What we learn now with Y2K can prepare us for a future where more and more failures of complex systems will confront us. It can also help us look beyond the confines of in-house systems and structures, and to see new, more effective ways to lead our business and social institutions.
