This book aims to give an overview of recent developments in indoor near-infrared optical wireless communication technologies and systems, including basic theories, operating fundamentals, system architectures, modelling, experimental demonstrations, advanced techniques, and most recently, the research efforts towards integrations. Both line-of-sight and diffusive-signals-based options will be reviewed, to provide readers a complete picture about this rapidly developing area, which targets...

This thesis presents an in-depth, high-resolution observational study on the very beginning of the formation process: the fragmentation of dense molecular clouds known as infrared dark clouds (IRDCs). Using the Submillimeter Array (SMA) and Very Large Array (VLA) radio interferometers, the author has discovered a common picture of hierarchical fragmentation that challenges some of the leading theoretical models and suggests a new, observation-driven understanding of how massive star format...

Based on rare first-hand historical data, Wang Ke presents the analysis of the East Turkestan from the perspective of Islamic social structure, the origin and evolution of thoughts on national revolution, the power structure of the Republic, and international politics. The original Japanese edition of this book has been recognized as the most authoritative research work on the independence movement of East Turkestan. This revised, enriched English edition provides valuable references for t...

This book provides a comprehensive overview of the exact boundary controllability of nodal profile, a new kind of exact boundary controllability stimulated by some practical applications. This kind of controllability is useful in practice as it does not require any precisely given final state to be attained at a suitable time t=T by means of boundary controls, instead it requires the state to exactly fit any given demand (profile) on one or more nodes after a suitable time t=T by means of ...

Charts Western influence and national development.

Gaining access to high-quality data is a vital necessity in knowledge-based decision making. But data in its raw form often contains sensitive information about individuals. Providing solutions to this problem, the methods and tools of privacy-preserving data publishing enable the publication of useful information while protecting data privacy. Int

In the connected highlands of southwest China, Vietnam, and Laos, recalling the past is a highly sensitive act. Among local societies, many may actively avoid recalling the past for fear of endangering themselves and others. Oral traditions and rare archives remain the main avenues to visit the past, but the national revolutionary narrative and the language of heritagization have strongly affected the local expression of historical memory. Yet this does not prevent local societies from pro...

This book aims to present an overview of China’s pension reform by first comprehensively analyzing the population aging situation, including its characteristics and future trends predicted through various models. It then examines the current state of the pension system, from its composition and reform history to the details of the endowment insurance fund. It further explores the reasons for reform, considering both external pressures and internal parameter limitations. Moreover, it looks ...
