IN THE NEWSWeimin Wu: pioneer physicist on Chinese science's turbulent past, promising futureTimes Higher Education, 25 February 2016While the first 30 years of new China's scientific development was a self-reliant era marked by the detonations of the atomic bomb, the hydrogen bomb, and the launch of the first artificial satellite, the second 30 years after the reform and opening up was signified by the introduction of the Internet to China. Weimin Wu is a unique legendary figure whose career spanned both periods. He not only contributed to the bomb and satellite projects, but also sent out the email from China to Switzerland in 1986, which was listed as the first event in the history of China's Internet development. The Tiananmen Square Protest in 1989 changed his life's trajectory, leading him to eventually immigrate to the US. His personal emotional life is also remarkable. With his experiences immersed in both Eastern and Western cultures, Wu came to believe in the convergence theory of social development, which provides a refreshing perspective for the readers. The autobiography records the details of his legendary life stories, from taking pictures with the Chinese leader Mao Zedong, to shaking hands with Deng Xiaoping; from being removed from the Institute of High Energy Physics, to the repealing of his Chinese passport. The story line is full of engaging ups and downs. In that turbulent era, Wu's rich emotional experiences and love stories were also a mirror for the Chinese society, with some details comparable to the plots of suspense novels and movies. The book is well illustrated with many pictures and flows smoothly with a simple writing style. The stories are factual and moving, all too realistic. The author has sincerely revealed his true self to the reader, and at the same time, faithfully described that period of history, giving the reader a grasp on the true workings of history. His comparison of the Eastern and Western cultures, analysis of science and superstition, interpretation of religion and arts, and his 'convergence' theory of social development, are all unique and insightful. This book faithfully tells Weimin's professional and personal life on the cusp and takes readers on a journey to explore true history through an ordinary person's stories.

This book presents a hybrid static-dynamic approach for efficient performance analysis of parallel applications on HPC systems. Performance analysis is essential to finding performance bottlenecks and understanding the performance behaviors of parallel applications on HPC systems. However, current performance analysis techniques usually incur significant overhead. Our book introduces a series of approaches for lightweight performance analysis. We combine static and dynamic analysis to reduce the overhead of performance analysis. Based on this hybrid static-dynamic approach, we then propose several innovative techniques for various performance analysis scenarios, including communication analysis, memory analysis, noise analysis, computation analysis, and scalability analysis. Through these specific performance analysis techniques, we convey to readers the idea of using static analysis to support dynamic analysis. To gain the most from the book, readers should have a basic grasp of parallel computing, computer architecture, and compilation techniques.
This volume puts forth an original theoretical framework, the ludonarrative model, for studying video games which foregrounds the empirical study of the player experience. The book provides a comprehensive introduction to and description of the model, which draws on theoretical frameworks from multimodal discourse analysis, game studies, and social semiotics, and its development out of participant observation and qualitative interviews from the empirical study of a group of players. The volume then applies this approach to shed light on how players’ experiences in a game influence how they understand and make use of game components in order to progress its narrative. The book concludes with a frame by frame analysis of a popular game to demonstrate the model’s principles in action and its subsequent broader applicability to analyzing video game interaction and design. Offering a new way forward for video game research, this volume is key reading for students and scholars in multimodality, discourse analysis, game studies, interactive storytelling, and new media.

This book focuses on the theoretical aspects of small strain theory of elastoplasticity with hardening assumptions. It provides a comprehensive and unified treatment of the mathematical theory and numerical analysis. It is divided into three parts, with the first part providing a detailed introduction to plasticity, the second part covering the mathematical analysis of the elasticity problem, and the third part devoted to error analysis of various semi-discrete and fully discrete approximations for variational formulations of the elastoplasticity. This revised and expanded edition includes material on single-crystal and strain-gradient plasticity. In addition, the entire book has been revised to make it more accessible to readers who are actively involved in computations but less so in numerical analysis. Reviews of earlier edition: “The authors have written an excellent book which can be recommended for specialists in plasticity who wish to know more about the mathematical theory, as well as those with a background in the mathematical sciences who seek a self-contained account of the mechanics and mathematics of plasticity theory.” (ZAMM, 2002) “In summary, the book represents an impressive comprehensive overview of the mathematical approach to the theory and numerics of plasticity. Scientists as well as lecturers and graduate students will find the book very useful as a reference for research or for preparing courses in this field.” (Technische Mechanik) "The book is professionally written and will be a useful reference to researchers and students interested in mathematical and numerical problems of plasticity. It represents a major contribution in the area of continuum mechanics and numerical analysis." (Math Reviews)

This work provides a posteriori error analysis for mathematical idealizations in modeling boundary value problems, especially those arising in mechanical applications, and for numerical approximations of numerous nonlinear var- tional problems. An error estimate is called a posteriori if the computed solution is used in assessing its accuracy. A posteriori error estimation is central to m- suring, controlling and minimizing errors in modeling and numerical appr- imations. In this book, the main mathematical tool for the developments of a posteriori error estimates is the duality theory of convex analysis, documented in the well-known book by Ekeland and Temam ([49]). The duality theory has been found useful in mathematical programming, mechanics, numerical analysis, etc. The book is divided into six chapters. The first chapter reviews some basic notions and results from functional analysis, boundary value problems, elliptic variational inequalities, and finite element approximations. The most relevant part of the duality theory and convex analysis is briefly reviewed in Chapter 2.
