This book investigates in detail the emerging deep learning (DL) technique in computational physics, assessing its promising potential to substitute conventional numerical solvers for calculating the fields in real-time. After good training, the proposed architecture can resolve both the forward computing and the inverse retrieve problems. Pursuing a holistic perspective, the book includes the following areas. The first chapter discusses the basic DL frameworks. Then, the steady heat conduction problem is solved by the classical U-net in Chapter 2, involving both the passive and active cases. Afterwards, the sophisticated heat flux on a curved surface is reconstructed by the presented Conv-LSTM, exhibiting high accuracy and efficiency. Besides, the electromagnetic parameters of complex medium such as the permittivity and conductivity are retrieved by a cascaded framework in Chapter 4. Additionally, a physics-informed DL structure along with a nonlinear mapping module are employed to obtain the space/temperature/time-related thermal conductivity via the transient temperature in Chapter 5. Finally, in Chapter 6, a series of the latest advanced frameworks and the corresponding physics applications are introduced. As deep learning techniques are experiencing vigorous development in computational physics, more people desire related reading materials. This book is intended for graduate students, professional practitioners, and researchers who are interested in DL for computational physics.

The true measure of any society is how it treats its children, who are in turn that society's future. Making use of data from the longitudinal Chinese Family Panel Studies survey, the authors of this timely study provide a multi-faceted description and analysis of China's younger generations. They assess the economic, physical, and social-emotional well-being as well as the cognitive performance and educational attainment of China's children and youth. They pay special attention to the significance of family and community contexts, including the impact of parental absence on millions of left-behind children. Throughout the volume, the authors delineate various forms of disparities, especially the structural inequalities maintained by the Chinese Party-state and the vulnerabilities of children and youth in fragile families and communities. They also analyze the social attitudes and values of Chinese youth. Having grown up in a period of sustained prosperity and greater individual choice, the younger Chinese cohorts are more independent in spirit, more open-minded socially, and significantly less deferential to authority than older cohorts. There is growing recognition in China of the importance of investing in children's future and of helping the less advantaged. Substantial improvements in child and youth well-being have been achieved in a time of growing economic prosperity. Strong political commitment is needed to sustain existing efforts and to overcome the many obstacles that remain. This book will be of considerable interest to researchers of Chinese society and development.

This monograph offers a detailed analysis of the creation, pilot implementation, and possible wide adoption of the real property tax at the local level in China. Starting in 2003, as China's economy gradually recovered from the Asian financial crisis that started in 1998, the real property market entered a period of rapid expansion, followed immediately by rampant speculation, rising housing costs, and official corruption. Over the last ten years, the price of real property in most cities has more than tripled, especially in metropolitan areas. In an effort to curb this, the government has instituted a number of property-market controls, including property tax pilot programs in Shanghai and Chongqing. While this is the latest of a number of fiscal reforms, it is a very important one that carries with it the ability to change the landscape of public finance, intergovernmental relations, and local governance in China. It represents a fundamental change in the provision of public services, the relationship between local governments and tax payers, and the status of localities in the government structure. Taking a public choice perspective, the authors argue that the local property tax should be used not solely as a means of controlling housing prices but should be fully employed as a fiscal and budgetary institution that will contribute to mitigating multifarious socio-economic problems resulting from economic growth, rapid urbanization, and widening income disparity. As this program is the first of its kind, so this book is the first detailed study of property tax in China; as such, it will appeal to researchers of public finance and public policy. It will also be of great interest to policymakers in China and in other countries that are considering adopting or reforming their versions of the local property tax. It fills the gap in a growing body of literature about the inner workings of Chinese economics and policy.

China's concentrated HIV epidemic is on the brink of becoming a generalized one and syphilis infection has become a major public health threat. Social factors relating to gender and gender inequality exacerbate the spread of HIV and sexually transmitted infections (STI) in China. A better understanding of the proximate social determinants of HIV related to gender will be crucial to effectively curbing HIV and other STIs in China. Aspects of China's governance - including administrative procedures, the developing legal system, social institutions, and the public health infrastructure - are instrumental in shaping strategies and responses to HIV. International studies suggest that women who are more economically and socially vulnerable may also have a greater risk of HIV infection, yet few initiatives have focused on discrete areas where achievable and sustainable gender policy measures could be linked to the public health response. This study presents perspectives ranging from criminology to social psychology to better understand how gender perspectives can inform HIV policy in the context of China.

This book investigates in detail the deep learning (DL) techniques in electromagnetic (EM) near-field scattering problems, assessing its potential to replace traditional numerical solvers in real-time forecast scenarios. Studies on EM scattering problems have attracted researchers in various fields, such as antenna design, geophysical exploration and remote sensing. Pursuing a holistic perspective, the book introduces the whole workflow in utilizing the DL framework to solve the scattering problems. To achieve precise approximation, medium-scale data sets are sufficient in training the proposed model. As a result, the fully trained framework can realize three orders of magnitude faster than the conventional FDFD solver. It is worth noting that the 2D and 3D scatterers in the scheme can be either lossless medium or metal, allowing the model to be more applicable. This book is intended for graduate students who are interested in deep learning with computational electromagnetics, professional practitioners working on EM scattering, or other corresponding researchers.
