Book excerpt: L'objectif de cette thèse est d'étudier l'accélaration et le transport des particules énergétiques solaires. La première partie de mon travail porte sur les particules énergétiques solaires à la Terre. A partir des données multi-instruments, je montre que les particules sont accélérées aux énergies relativistes lors d'un épisode d'accélaration spécifique de la phase impulsive, et que la distance parcourue par les particules est plus longue que la distance théorique. En utilisant des mesures in-situ du champ magnétique et du plasma, j'ai identifié les structures magnétiques interplanétaires guidant les particules pour 10 évènements. Je montre alors que la structure interplanétaire diffère la plupart du temps du milieu interplanétaire standard, et peut donc fortement influer sur le transport interplanétaire des particules. Dans un second volet, j'ai étudié le rôle macroscopique de la dynamique de la reconnexion magnétique dans l'injection et le transport de particules dans la couronne solaire. J'ai réalisé la première simulation 3D magnéto-hydrodynamique (MHD) contrainte par les observations, d'un évènement observé. J'ai montré que la dynamique des rubans observés s'explique par la succession de différents régimes de reconnexion : au point nul et glissant, induit par la présence de quasi-séparatrices entourant les séparatrices. Grâce à une simulation MHD d'une telle topologie hybride dans un champ ouvert, je montre que les particules accélérées au site de reconnexion peuvent être injectées dans un tube de flux étendu, formé par la reconnexion glissante, produisant ainsi un faisceau de particules balayant une large gamme de longitude dans le milieu interplanétaire.

Available in PDF, EPUB and Kindle. Book excerpt: This book is an introduction to differential manifolds. It gives solid preliminaries for more advanced topics: Riemannian manifolds, differential topology, Lie theory. It presupposes little background: the reader is only expected to master basic differential calculus, and a little point-set topology. The book covers the main topics of differential geometry: manifolds, tangent space, vector fields, differential forms, Lie groups, and a few more sophisticated topics such as de Rham cohomology, degree theory and the Gauss-Bonnet theorem for surfaces. Its ambition is to give solid foundations. In particular, the introduction of “abstract” notions such as manifolds or differential forms is motivated via questions and examples from mathematics or theoretical physics. More than 150 exercises, some of them easy and classical, some others more sophisticated, will help the beginner as well as the more expert reader. Solutions are provided for most of them. The book should be of interest to various readers: undergraduate and graduate students for a first contact to differential manifolds, mathematicians from other fields and physicists who wish to acquire some feeling about this beautiful theory. The original French text Introduction aux variétés différentielles has been a best-seller in its category in France for many years. Jacques Lafontaine was successively assistant Professor at Paris Diderot University and Professor at the University of Montpellier, where he is presently emeritus. His main research interests are Riemannian and pseudo-Riemannian geometry, including some aspects of mathematical relativity. Besides his personal research articles, he was involved in several textbooks and research monographs.

Book excerpt: Aeronomy, Part A is an attempt to make a comprehensive exposition of the processes in aeronomy, the study of composition, movement, and thermal balance of the upper regions of the planetary atmosphere. The text covers topics such as atmospheric regions and atmospheric density, the temperature and molecular mass of the atmosphere; the permanent constituents and the molecular and isotonic composition of the homosphere; and the transition from the homosphere to the heterosphere. Also covered are topics such as the temperature gradient and energies in the thermosphere, conditions at 200km and above 250km, solar radiation and ionization, and aeronomic reactions. The book is recommended for scientists, especially natural physicists, who would like to know more about the field of aeronomy and its advances.

Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage, devenu célèbre sous son sigle MCSE, a déjà été utilisé par plus de 50 000 étudiants, chercheurs, professionnels. L'objectif est de lire et écrire des textes en anglais scientifique avec facilité et pertinence. L'ouvrage est conçu pour que l'apprenant devienne un véritable utilisateur de l'anglais. La méthode originale repose sur l'analyse des fonctions et structures nécessaires : measurement, frequency, comparison, modification, link words, time, cause and consequence, hypothesis, modality, purpose and process, impersonal forms, compound nouns and adjectives. Dans chaque unit, des tests d'auto-évaluation permettent de se situer et de construire son parcours de formation, d'abord en définissant ses objectifs à l'aide des key points et du lexis, puis, de façon plus personnalisée, en puisant dans les examples in context, checkpoints (back to basics, word web), web search, FAQs... MCSE est l'outil de base d'une méthode qui comprend aussi d'autres outils dans la même collection (Listening Comprehension for Scientiflc English et Speaking Skills in Scientitic English). L'ouvrage est destiné à tout apprenant de niveau baccalauréat qui désire acquérir une réelle compétence dans l'écriture et la lecture de textes en anglais scientifique.

Available in PDF, EPUB and Kindle. Book excerpt: There is no strict definition of unconventional computing. Being an unconventional computist is not a matter of training but thinking and living. Phenomenologically most works on unconventional computing are about implementation of computing in novel substrates (chemical, physical, biological), development of computing schemes and algorithms not fitting into the mainstream framework, or designing of computing architectures inspired by chemical or biological systems. This short book gives a snapshot of the unconventional computing field. The world-leading experts in the unconventional computing author all articles of the issue. The topics include analog computation, sensing and computing with fungi, chemical computing, swarms of minimalist agents, computational universality, mega-computing in the universe, information and music, universal sensing, art of deduction, reversible computing, philosophy of machine learning, epistemic incompleteness, post-quantum unconventional computing, complexity of natural computing, arts and cellular automata. Articles presented are punchy and well illustrated. All articles are short and self-contained. The book will serve well as a light-touch introduction to unconventional computing for people not familiar with computing and might inspire artists and humanitarians to enter the field.
