This textbook gives an instructive view of solitons and their applications for advanced students of physics.
Critiques global mediascape through feminist perspectives, highlighting concerns of policy, power, labor, and technology. Starting with the state of international communications, this work covers cases on online news, pornography, democracy, policies for women's development, violence against women, information workers, print media and telecentres.
In the last few years, hopes have emerged that simple concepts could perhaps explain the extremely complicated biomolecular processes which are known to a greater and greater accuracy thanks to the extraordinary progress of biology. In parallel, powerful methods in physics, especially nonlinearity and cooperative effects, have been developed. They apply especially to biological phenomena and can explain coherent excitations with remarkable properties. This book provides a pedagogical introduction to the theory of nonlinear excitations and solitons in a biological environment, and also to the structure and function of biomolecules as well as energy and charge transport in biophysics.
Offering an up-to-date historical perspective which should enable readers to fathom how the brutal massacres of 800,000 Rwandese came to pass in 1994, this volume includes a new chapter that brings the analysis up to the end of 1996. Gerard Prunier probes into how the genocidal events in Rwanda were part of a deadly logic - a plan that served central political and economic interests - rather than a result of primordial tribal hatreds, a notion often invoked by the media to dramatize genocide.
Human consciousness has perplexed philosophers, artists and scientists for centuries. Some hold it to be purely physical, while others believe it transcends the material world. Now comes a book that offers a new perspective - based entirely on evidence from the natural sciences - whereby materialism and dualism co-exist. The author - a distinguished pioneer of nonlinear dynamics - bases his argument on a hierarchical view of mental organization; a stairway. Atoms give rise to molecules, neurons form the brain and individual consciousness leads to shared culture. All steps are needed to complete the picture and each level derives from the previous one. The book shows specialists how each of their fields adds to the overall picture, while providing general readers with an introduction to this investigation.
Leading scientists discuss the most recent physical and experimental results in the physics of Bose-Einstein condensate theory, the theory of nonlinear lattices (including quantum and nonlinear lattices), and nonlinear optics and photonics. Classical and quantum aspects of the dynamics of nonlinear waves are considered. The contributions focus on the Gross-Pitaevskii equation and on the quantum nonlinear Schrödinger equation. Recent experimental results on atomic condensates and hydrogen bonded systems are reviewed. Particular attention is given to nonlinear matter waves in periodic potential.

This book provides an introduction to localised excitations in spatially discrete systems, from the experimental, numerical and mathematical points of view. Also known as discrete breathers, nonlinear lattice excitations and intrinsic localised modes, these are spatially localised time periodic motions in networks of dynamical units. Examples of such networks are molecular crystals, biomolecules, and arrays of Josephson superconducting junctions. The book also addresses the formation of discrete breathers and their potential role in energy transfer in such systems.
The power of modelization in physics and in engineering is not in doubt, while in the biotechnological field many theoretical studies stop at the description level. It is time for theoretical modelization to enter the field of biotechnology, and that needs people with both physical and biological knowledge.This book introduces interested scientists with varied backgrounds to active research in different areas broadly related to what has come to be called ?dynamical modeling in biology?.
