'I used to be ever so small, hardly as high as a dandelion. Until I grew tall enough to tickle the clouds.' Telling the life story of a single tree, and of all the creatures that have nestled in its branches, this is a gorgeously illustrated?ode to the web of life that connects everything in the natural world.

This book provides the first graduate-level, self-contained introduction to recent developments that lead to the formulation of the configuration-interaction approach for open quantum systems, the Gamow shell model, which provides a unitary description of quantum many-body system in different regimes of binding, and enables the unification in the description of nuclear structure and reactions. The Gamow shell model extends and generalizes the phenomenologically successful nuclear shell model to the domain of weakly-bound near-threshold states and resonances, offering a systematic tool to understand and categorize data on nuclear spectra, moments, collective excitations, particle and electromagnetic decays, clustering, elastic and inelastic scattering cross sections, and radiative capture cross sections of interest to astrophysics. The approach is of interest beyond nuclear physics and based on general properties of quasi-stationary solutions of the Schrödinger equation – so-called Gamow states. For the benefit of graduate students and newcomers to the field, the quantum-mechanical fundamentals are introduced in some detail. The text also provides a historical overview of how the field has evolved from the early days of the nuclear shell model to recent experimental developments, in both nuclear physics and related fields, supporting the unified description. The text contains many worked examples and several numerical codes are introduced to allow the reader to test different aspects of the continuum shell model discussed in the book.

Conquête ottomane de l’Égypte (1517) est le premier ouvrage collectif consacré à la victoire de Selīm Ier sur les Mamelouks, qui a fait du sultanat ottoman l’unique puissance musulmane en Méditerranée orientale, et ravalé l’Égypte au rang de province. Il en renouvelle l’approche en faisant appel à des sources ottomanes, arabes et occidentales très variées.Les contributions réunies par Benjamin Lellouch et Nicolas Michel s’attachent à mesurer les transformations structurelles qu’a induites l’événement dans la société, les pouvoirs, la culture littéraire, artistique et matérielle en Égypte. Elles explorent ses antécédents et son impact géopolitique, et restituent les échos, bruyants puis assourdis, qu’il a suscités, au Proche-Orient, en Italie, et plus généralement en Méditerranée. Conquête ottomane de l’Égypte (1517) is the first collective work that deals with Selīm Ist’s crushing victory over the Mamluks, which made the Ottoman sultanate into the sole remaining Muslim power in the eastern Mediterranean, and reduced Egypt to the rank of a province. The book offers new insights into this major event by using a wide range of Ottoman and Arabic as well as Western sources. These essays in French and English collected by Benjamin Lellouch and Nicolas Michel examine to what extent the Ottoman conquest altered the structures of Egyptian society, power relations, literature, arts and material culture. They explore both its backgrounds and geopolitical aftermath, and reconstruct its echoes - loud at first, then gradually fading out - in the Middle East, Italy, and the Mediterranean.
