Global optimization ; Vol. 85 : Scientific and engineering case studies
Optimization models based on a nonlinear systems description often possess multiple local optima. The objective of global optimization (GO) is to find the best possible solution of multiextremal problems. Global Optimization: Selected Case Studies illustrates the applicability of GO modeling techniques and solution strategies to real-world problems.The contributed chapters cover a broad range of applications from agroecosystem management, assembly line design, bioinformatics, biophysics, black box systems optimization, cellular mobile network design, chemical process optimization, chemical product design, composite structure design, computational modeling of atomic and molecular structures, controller design for induction motors, electrical engineering design, feeding strategies in animal husbandry, the inverse position problem in kinematics, laser design, learning in neural nets, mechanical engineering design, numerical solution of equations, radiotherapy planning, robot design, and satellite data analysis. The solution strategies discussed encompass a range of practically viable methods, including both theoretically rigorous and heuristic approaches.
Gastroesophagal reflux disease (GERD)
Gastroesophageal reflux disease (GERD) is a common disease with a high prevalence worldwide and a great socioeconomic burden. GERD is a multifactorial disease in which anatomical and functional factors both play a pathogenetic role. The disease can manifest in various symptoms which can be grouped into typical, atypical and extra-esophageal symptoms. The pathophysiology of GERD is complex and not completely understood. An abnormal LES pressure and increased reflux during transient LES relaxations are believed to be key etiologic factors. Prolonged exposure of the esophagus to acid is another. Heartburn and acid regurgitation are the most common symptoms of GERD, although pathologic reflux can result in a wide variety of clinical presentations.

Fractures du genou = Knee fractures
Provides a comprehensive yet practical overview of the management of knee fractures and their complications. The editorial team comprises specialists from France, Switzerland, Belgium, the United States, and Ireland, many of whom are members of the AO group. Imaging strategies, assessment, classification, and anatomical variations are reviewed for each anatomical location. All therapeutic approaches are discussed without exception: conventional implants, intramedullary nailing, minimally invasive techniques, including the role of external fixation, and newer technologies such as the LISS. These approaches are subjected to critical analysis to identify the best options based on the indications and individual circumstances. The patellar apparatus is addressed in its functional unity. Postoperative management, influenced by functional prognosis, is also covered, as is the management of malunion, stiffness, and other complications. Finally, very specific problems are discussed, such as pediatric injuries, patellectomies, periprosthetic fractures, often complex projectile injuries, the role of immediate arthroplasty and massive grafts, but also associated injuries which sometimes have a heavy impact on the final prognosis.
Fisica solare = Solar physics
An introduction to Solar Physics, intended to illustrate to those who intend to approach this discipline (students, PhDs, researchers) the physical mechanisms underlying the complex phenomena observed on our closest star. It does not claim to be exhaustive (suffice it to say that solar physics spans a wide range of disciplines, such as nuclear physics, thermodynamics, electrodynamics, atomic and molecular physics, spectroscopy across all bands of the electromagnetic spectrum, magnetohydrodynamics, plasma physics, the development of new instrumentation, optics, etc.). Rather, a number of topics of fundamental relevance to the current study of the Sun have been selected (especially with regard to ground-based observations with large telescopes), and an attempt has been made to provide a general overview of these topics, including their historical evolution, without going into excessive detail. Since Solar Physics can rightfully be considered the "Rosetta Stone" of all Astrophysics, the volume can also be considered a valid introduction to this subject.
Field Emission in Vacuum Microelectronics
Field emission is a phenomenon described by quantum mechanics. Its emission capability is millions times higher than that of any other known types of electron emission. Nowadays this phenomenon is experiencing a new life due to wonderful applications in the atomic resolution microscopy, in electronic holography, and in the vacuum micro- and nanoelectronics in general. The main field emission properties, and some most remarkable experimental facts and applications, are described in this book.

Extreme Nonlinear Optics : An Introduction
Following the birth of the laser in 1960, the field of "nonlinear optics" rapidly emerged. Today, laser intensities and pulse durations are readily available, for which the concepts and approximations of traditional nonlinear optics no longer apply. In this regime of "extreme nonlinear optics," a large variety of novel and unusual effects arise, for example frequency doubling in inversion symmetric materials or high-harmonic generation in gases, which can lead to attosecond electromagnetic pulses or pulse trains. Other examples of "extreme nonlinear optics" cover diverse areas such as solid-state physics, atomic physics, relativistic free electrons in a vacuum and even the vacuum itself. This book starts with an introduction to the field based primarily on extensions of two famous textbook examples, namely the Lorentz oscillator model and the Drude model. Here the level of sophistication should be accessible to any undergraduate physics student. Many graphical illustrations and examples are given. The following chapters gradually guide the student towards the current "state of the art" and provide a comprehensive overview of the field. Every chapter is accompanied by exercises to deepen the reader's understanding of important topics, with detailed solutions at the end of the book.

Entropy Methods for the Boltzmann Equation : Lectures from a Special Semester at the Centre Émile Borel, Institut H. Poincaré, Paris, 2001
Entropy and entropy production have recently become mathematical tools for kinetic and hydrodynamic limits, when deriving the macroscopic behaviour of systems from the interaction dynamics of their many microscopic elementary constituents at the atomic or molecular level. During a special semester on Hydrodynamic Limits at the Centre Émile Borel in Paris, 2001 two of the research courses were held by C. Villani and F. Rezakhanlou. Both illustrate the major role of entropy and entropy production in a mutual and complementary manner and have been written up and updated for joint publication. Villani describes the mathematical theory of convergence to equilibrium for the Boltzmann equation and its relation to various problems and fields, including information theory, logarithmic Sobolev inequalities and fluid mechanics. Rezakhanlou discusses four conjectures for the kinetic behaviour of the hard sphere models and formulates four stochastic variations of this model, also reviewing known results for these.
Endoscopic Surgery of the Potential Anatomical Spaces
Potential anatomical spaces" have attracted surgeons in the past and in recent years. Due to the development of modern imaging techniques and the advent of minimally invasive surgery, access to these spaces has become a real surgical option. The purpose of this book is to document the challenges related to "potential anatomical spaces", traditionally described as "hidden" spaces. The spread of video-assisted surgery and its application in the management of diseases involving organs or anatomical structures placed in the "potential spaces" (neck, mediastinum, pro-peritoneum and retro-peritoneum, subfacial space of the leg, and axilla), has rendered their surgical anatomy less abstract.
Endoscopic Oncology

Endoscopic Anatomy of the Third Ventricle : Microsurgical and Endoscopic Approaches
In this atlas anatomical aspects important for combinations of microsurgical and endoscopic approaches are presented and illustrated. Modern imaging techniques are necessary for the three-dimensional orientation but do not show enough details for endoscopic interventions. The small visual fields need a combination of the depiction of fine details and of the three-dimensional presentation of large areas. Furthermore, problems with little known anatomical standard variants of the target areas may arise. Therefore, numerous common anatomical variants are demonstrated with reference to their impact for the surgical technique.
Emergent Nonlinear Phenomena in Bose-Einstein Condensates : Theory and Experiment
This book, written by experts in the fields of atomic physics and nonlinear science, consists of reviews of the current state of the art at the interface of these fields, as is exemplified by the modern theme of Bose-Einstein condensates. Topics covered include bright, dark, gap and multidimensional solitons; vortices; vortex lattices; optical lattices; multicomponent condensates; manipulation of condensates; mathematical methods/rigorous results; and aspects beyond the mean field approach. A distinguishing feature of the contents is the detailed incorporation of both the experimental and theoretical viewpoints through subsections of the relevant chapters.
Electrostatic Accelerators : Fundamentals and Applications
Electrostatic accelerators are an important and widespread subgroup within the broad spectrum of modern, large particle acceleration devices. They are specifically designed for applications that require high-quality ion beams in terms of energy stability and emittance at comparatively low energies (a few MeV). Their ability to accelerate virtually any kind of ion over a continuously tunable range of energies make them a highly versatile tool for investigations in many research fields including, but not limited to, atomic and nuclear spectroscopy, heavy ion reactions, accelerator mass spectroscopy as well as ion-beam analysis and modification. The book is divided into three parts. The first part concisely introduces the field of accelerator technology and techniques that emphasize their major modern applications. The second part treats the electrostatic accelerator per se: its construction and operational principles as well as its maintenance. The third part covers all relevant applications in which electrostatic accelerators are the preferred tool for accelerator-based investigations. Since some topics are common to all types of accelerators, Electrostatic Accelerators will also be of value those more familiar with other types of accelerators.
Electron Scattering : From Atoms, Molecules, Nuclei and Bulk Matter
There is a unity to physics; it is a discipline which provides the most fundamental understanding of the dynamics of matter and energy. To understand anything about a physical system you have to interact with it and one of the best ways to learn something is to use electrons as probes. This book is the result of a meeting, which took place in Magdalene College Cambridge in December 2001. Atomic, nuclear, cluster, soHd state, chemical and even bio- physicists got together to consider scattering electrons to explore matter in all its forms. Theory and experiment were represented in about equal measure. It was meeting marked by the most lively of discussions and the free exchange of ideas. We all learnt a lot. The Editors are grateful to EPSRC through its Collaborative Computational Project program (CCP2), lOPP, the Division of Atomic, Molecular, Optical and Plasma Physics (DAMOPP) and the Atomic Molecular Interactions group (AMIG) of the Institute of Physics for financial support. The smooth running of the meeting was enormously facilitated by the efficiency and helpfulness of the staff of Magdalene College, for which we are extremely grateful.
