"Gauge Theory of Weak Interactions" treats the unification of electromagnetic and weak interactions and considers related phenomena. First, the Fermi theory of beta decay is presented, followed by a discussion of parity violation, clarifying the importance of symmetries. Then the concept of a spontaneously broken gauge theory is introduced, and all necessary mathematical tools are carefully developed. The "standard model" of unified electroweak interactions is thoroughly discussed including current developments. The final chapter contains an introduction to unified theories of strong and electroweak interactions. Numerous solved examples and problems make this volume uniquely suited as a text for an advanced course. This fourth edition has been carefully revised.

L'ouvrage traite d'un concept particulièrement attractif du cours de mécanique quantique avancé, c'est à dire les symétries. Après une brève introduction aux symétries en mécanique classique, le texte s'attache à leur place en mécanique quantique, aux conséquences de la symétrie de rotation, ainsi qu'à la théorie générale des groupes de Lie. Les groupes isospin, l'hypercharge SU(3), et leurs applications sont traités avant les chapitres sur les quarks et leur charme, SU(4), ainsi que les symétries dynamiques et les frontières de la recherche en physique des particules. Ce texte unique comprend plus de 120 problèmes et exercices très détaillés et corrigés, afin d'en faire l'ouvrage de référence en la matière.

During the last few years there has been a rapidly increasing interest in neural modeling of brain and cognitive disorders. This multidisciplinary book presents a variety of such models in neurology, neuropsychology and psychiatry. A review of work in this area is given first. Computational models are then presented of memory impairment in Alzheimer's disease, functional brain reorganization following a stroke, patterns of neural activity in epilepsy, disruption of language processes in aphasia and acquired dyslexia, altered cognitive processes in schizophrenia and depression, and related disorders. This is the first book on this topic, with contributions from many of the leading researchers in this field.

Neural Networks presents concepts of neural-network models and techniques of parallel distributed processing in a three-step approach: - A brief overview of the neural structure of the brain and the history of neural-network modeling introduces to associative memory, preceptrons, feature-sensitive networks, learning strategies, and practical applications. - The second part covers subjects like statistical physics of spin glasses, the mean-field theory of the Hopfield model, and the "space of interactions" approach to the storage capacity of neural networks. - The final part discusses nine programs with practical demonstrations of neural-network models. The software and source code in C are on a 3 1/2" MS-DOS diskette can be run with Microsoft, Borland, Turbo-C, or compatible compilers.
