Au bord d'une rivière éternelle, trois revenants se rencontrent. Réincarnés en animaux mal-aimés - rat, mouche, serpent -, ils ont l'impression de se trouver en meilleure situation que jadis, lorsqu'ils vivaient sous forme humaine. Comme cette vie d'avant les hante toujours, ils entreprennent de raconter leur version des faits, exprimant leurs hontes, leurs remords et parfois leur amertume. Surtout, ils relatent leurs souvenirs d'un maître commun, toujours omniprésent, envers qui ils éprouvent maintenant des émotions complexes et dont ils remettent en question l'enseignement.
De l'autre côté du fleuve, en regard de notre ville, un tremblement de terre a eu lieu il y a quelque temps, mais la ville d'en face se porte à merveille, s'accroît de jour en jour, les derniers morceaux de terre cultivable viennent d'être achetés, les nouveaux immeubles seront bientôt en place. La paix y règne. Les jardins bâtis sur les cadavres et nourris de sang fleurissent bien. La prospérité se prolonge sans fin. Aucun signe d'écroulement. Le paradis existe. Le progrès est possible.Ying Chen, née à Shanghai, vit à Vancouver. Elle écrit directement en français. Elle avait été remarquée avec L'Ingratitude (Actes Sud, 1995). Elle jouit d'un grand prestige au Canada, où de nombreuses thèses ont été consacrées à son oeuvre. Elle est traduite dans plusieurs langues. La rive est loin est son septième livre publié au Seuil.
Avec cette manière si personnelle d'évoquer des destins en faisant dialoguer les vivants et les morts, Ying Chen raconte ici merveilleusement la vie d'une illustre femme de science par la voix de sa fille, devenue à dix-huit ans son assistante sur les champs de bataille et, par la suite, dans son laboratoire. Comment ne pas penser à Marie Curie et à sa fille Irène dans cette remémoration d'outre-tombe qui fait revivre la destinée de ces deux scientifiques ainsi que d'autres membres tout aussi illustres de cette famille, leurs aléas dans l'histoire et aussi leurs combats.
This book provides a comprehensive review and in-depth discussion of the state-of-the-art research literature and propose energy-efficient computation offloading and resources management for mobile edge computing (MEC), covering task offloading, channel allocation, frequency scaling and resource scheduling. Since the task arrival process and channel conditions are stochastic and dynamic, the authors first propose an energy efficient dynamic computing offloading scheme to minimize energy consumption and guarantee end devices' delay performance. To further improve energy efficiency combined with tail energy, the authors present a computation offloading and frequency scaling scheme to jointly deal with the stochastic task allocation and CPU-cycle frequency scaling for minimal energy consumption while guaranteeing the system stability. They also investigate delay-aware and energy-efficient computation offloading in a dynamic MEC system with multiple edge servers, and introduce anend-to-end deep reinforcement learning (DRL) approach to select the best edge server for offloading and allocate the optimal computational resource such that the expected long-term utility is maximized. Finally, the authors study the multi-task computation offloading in multi-access MEC via non-orthogonal multiple access (NOMA) and accounting for the time-varying channel conditions. An online algorithm based on DRL is proposed to efficiently learn the near-optimal offloading solutions.
Researchers working in mobile edge computing, task offloading and resource management, as well as advanced level students in electrical and computer engineering, telecommunications, computer science or other related disciplines will find this book useful as a reference. Professionals working within these related fields will also benefit from this book.

De nombreuses oeuvres littéraires ont voulu cerner, ces dernières années, la difficulté de la situation de l'immigrant, qui doit embrasser une nouvelle culture sans jamais parvenir à oublier tout à fait celle dont il est issu. Ce livre pose une question encore bien plus profonde et complexe. Comment un immigrant peut-il rendre compte de ce choix auprès de ses enfants ? Si l'adulte a choisi son nouveau pays, l'enfant, lui, n'a rien choisi. Qu'est-ce qui peut alors racheter l'immense douleur de se retrouver sans racines ?
Sous forme d'une longue lettre adressée à son fils, la romancière Ying Chen signe ici un livre bouleversant d'intelligence et de sensibilité. Comment lui parler de son héritage chinois quand elle a elle-même choisi le Canada pour pays et la langue française comme lieu de déploiement de son imaginaire ? Comment lui parler de Lao-Tseu, s'il ne lui est accessible qu'à travers une traduction dans une langue occidentale ? Comment lui parler des livres quand les images règnent sur le monde dans lequel il vit ?

Volume 1 of a 4-volume series is a concise, authoritative and an eminently readable and enjoyable experience related to hydrogen production, storage and usage for portable and stationary power. Although the major focus is on hydrogen, discussion of fossil fuels and nuclear power is also presented where appropriate. This monograph is written by recognized experts in the field, and is both timely and appropriate as this decade will see application of hydrogen as an energy carrier, for example in transportation sector.
The world's reliance on fossil fuels is due to the ever growing need for energy to sustain life and on-going progress; however exploitation also brings consequences such as emission of carbon, nitrogen and sulfur dioxides into the atmosphere. The collective influence of these photochemical gases is production of acid rain and an alternation of global temperatures, leading to record high temperatures in many parts of the world. The fossil fuel is unsustainable andthus there is a critical need for alternative sustainable energy resources. One universal energy carrier is hydrogen, which is the focus of this volume.
This book is suitable for those who work in the energy field as technical experts, including engineers and scientists, as well as managers, policy and decision-makers, environmentalists and consultants. Students and practitioners such as lectures, teachers, legislators and their aids in the field of energy will find this book invaluable and a practical handbook or guide in the field of sustainable energy with emphasis on hydrogen as an energy carrier.

This book explores the dynamics of the Chinese labor market, the largest in the world. The sheer scale of rural laborers living in cities is the ultimate engine driving the fastest urbanization the world has ever seen. Today, the country faces a series of new challenges as it tries to address problems of unemployment and under-employment. These include population ageing, automation, the increasing use of AI on the factory floor and other workplaces and Chinese manufacturers' move up the value chain. The book presents an empirically rich and analytically rigorous account of how these challenges might be met. It will be of interest to labor economists, scholars of Chinese manufacturing, and researchers of the Chinese economy.
This book estimates terrestrial vegetation carbon sequestration data based on remote sensing satellite data, collects the temporal and spatial characteristics of carbon sequestration by vegetation at county level and grid scale in China, and predicts the future change of carbon sequestration by vegetation in China. Based on the major strategic development goals and specific practices of China's carbon neutrality, this book shifts the research perspective from the side of carbon reduction to the weaker side of carbon sequestration. It not only broadens and enriches the research boundaries and theoretical connotation in the field of carbon neutrality, but also provides a perspective reference for further research on carbon sequestration by vegetation, which has pioneering academic value for future research on carbon dioxide. The satellite data is collected to calculate China's long time series and multi-type district and county vegetation carbon sequestration data set, which can meet different research needs and application scenarios. The practical value lies in providing basic data for the research of carbon neutrality, the establishment of carbon trading market and the calculation of vegetation carbon sink, and providing an important reference index for evaluating the ecological and environmental effects of land change. This book combines remote sensing technology, Geographic Information Science (GIS), spatial visualization technology and index decomposition technology to measure vegetation carbon sequestration in counties and districts of China, reveals the spatial-temporal dynamic change process of vegetation carbon sequestration, and explores the driving influence of social factors.
