C N Yang is a towering figure of science who has significantly extended human understanding of nature, headed one of the foremost research institutes in physics for three decades, and made great contributions to the advances of Chinese physics. This Festschrift in honor of Professor Yang on his centenary birthday consists of two volumes: Volume A consists of general essays concerning Professor Yang the person, as well as the authors'impressions and reminiscences of him, which are mainly (but not exclusively) in Chinese. This volume, that is Volume B, consists of over thirty scientific papers in English on subjects broadly related to his work and contributed by two different groups: Professor Yang's colleagues, friends, and former students; and graduates from the Tsinghua University Physics Department or Institute for Advanced Study, who have come under the influence of Professor Yang and are now established in their own careers; review papers presented at a Symposium held in his honor in 2021 are also included. It is hoped that this Festschrift can serve as a fit tribute to Professor Yang's lifelong achievements, and also increase public awareness of the many different sides of this giant — his life, his personality, his work, his influence, as well as what he strives for.

This book presents a novel framework design for the next generation Marine Wireless Communication Networks (MWCNs). The authors first provide an overview of MWCNs, followed by a discussion of challenges in the design and development of MWCNs in support of a diversity of marine services such as real-time marine monitoring, offshore oil exploration, drilling, marine tourism and fishing. The authors then propose cross layer networking solutions to achieve a high performance modern MWCN that enables efficient and reliable data transmissions under hostile marine environment, which include the network deployment, the physical layer channel coding, intelligent network access and resource management, and learning-based opportunistic routing. Finally, the authors summarize the book and present some open issues that will lead to new research directions in the next generation MWCNs.

This book presents radiological findings in patients with 2019 Novel Coronavirus Pneumonia (COVID-19). It starts with a general review of COVID-19 Pneumonia discovery, including etiology characteristics, transmission routes and pathogenic mechanisms. In the following chapters, details in clinical classification, imaging manifestations in different groups, and imaging features of family aggregated coronavirus pneumonia are introduced. In addition, key points in differential diagnosis of COVID-19 Pneumonia are summarized in the last chapter. The book provides a valuable reference source for radiologists and doctors working in the area of COVID-19 Pneumonia.

This volume brings together conceptualizations and empirical studies that explore the socio-cultural dimension of new media and its implications on learning in the 21st century classroom. The authors articulate their vision of new-media-enhanced learning at a global level. The high-level concept is then re-examined for different degrees of contextualization and localization, for example how a specific form of new media (e-reader) changes specific activities in different cultures. In addition, studies based in Singapore classrooms provide insights as to how these concepts are being transformed and implemented by a co-constructive effort on the part of researchers, teachers and students. Singapore classrooms offer a unique environment to study the theory-practice nexus in that they are high achieving, implicitly grounded in the eastern cultural values and well-equipped with ICT infrastructure. While these studies are arguably the state-of-the-art exemplars that synergize socio-cultural and technological affordances of the current learning environments, they also serve as improvable ideas for further innovations. The interplay between theory and practice lends support to the reciprocal improvements for both. This book contributes to the continuing debate in the field, and will lead to better learning environments in the 21st century.
