This volume contains nine refereed research papers in various areas from combinatorics to dynamical systems, with computer algebra as an underlying and unifying theme. Topics covered include irregular connections, rank reduction and summability of solutions of differential systems, asymptotic behaviour of divergent series, integrability of Hamiltonian systems, multiple zeta values, quasi-polynomial formalism, Padé approximants related to analytic integrability, hybrid systems. The interactions between computer algebra, dynamical systems and combinatorics discussed in this volume should be useful for both mathematicians and theoretical physicists who are interested in effective computation.
The importance of molecular approaches for comparative biology and the rapid development of new molecular tools is unprecedented. The extraordinary molecular progress belies the need for understanding the development and basic biology of whole organisms. Vigorous international efforts to train the next-generation of experimental biologists must combine both levels – next generation molecular approaches and traditional organismal biology. This book provides cutting-edge chapters regarding the growing list of marine model organisms. Access to and practical advice on these model organisms have become a conditio sine qua non for a modern education of advanced undergraduate students, graduate s...
In this thoughtful and unprecedented biographical history, Willem-Jan Verlinden delves into previously unpublished correspondence in the Van Gogh family archives to bring Vincents three sisters out from their brothers shadow, poignantly portraying their dreams, disappointments and grief. The Van Gogh siblings grew up at a time when long-distance travel by train first became possible. As each went their own way, following work and study to London, Paris, Brussels and beyond, they maintained the close relationships forged in their youth in the idyllic Netherlands countryside by sending candid and personal letters. The oldest sister, Anna, worked as a governess in England as a young woman befor...
Une biographie de Jane Birkin, décédée le 16 juillet 2023, qui aborde la carrière de chanteuse et de comédienne de l'" ex-fan des sixties ", mais aussi le personnage populaire, aimé pour sa simplicité, qui a dû affronter bien des drames. Avec élégance, comme à la légère, Jane Birkin (1946-2023) aura assumé jusqu'au bout le rôle de " muse de Serge Gainsbourg ", alors qu'elle était plus justement son double féminin, sa " face B ", et sublimé son oeuvre à travers le monde. En retour, malgré sa tendance à se dévaloriser, elle est parvenue à se convaincre qu'il aurait été fier d'elle. Trop souvent réduite, pourtant, à ce statut d'icône de séduction, Jane Birkin a démontré par sa personnalité sensible, fantasque et tourmentée qu'elle était une artiste libre, éclectique, et une citoyenne engagée. Cette biographie présente un minutieux portrait de la femme et de l'artiste dont on aimait la générosité, la sensibilité " à fleur de peau ", la fantaisie et la sincérité. " La consolation de tout pour moi, ce sont les gens. En chantant, en parlant, c'est là que je suis heureuse et que je sers à quelque chose. " Elle était notre " Jane B. "
Since the previous Symposium, several exciting new developments and advances have occurred in the field of frequency standards and metrology. These include the first results on the long-tenn stability of a millisecond Pulsar, for which data 14 integrated over several years now show a stability of around 10- . Improvements in the understanding of various biases in Cesium beam standards promise accuracies in the low 14s for primary standards and in the low 13s for short commercial tubes, for which long tenn stabilities in low 14s have already been shown to be obtainable by accuracy improvement. Beams using optical pumping for state selection and for detection have been operated with excellent ...
