This book introduces readers to the navigation, guidance and control technologies involved in single-spacecraft, double-spacecraft, and multiple-spacecraft tasks in elliptical orbits. It comprehensively covers the key technologies of guidance, navigation and control (GNC) system design for spacecraft in elliptical orbits, including the orbit design, formation configuration design and maintenance, autonomous navigation technology and relative navigation technology, as well as autonomous rendezvous technology. The methods that this book introduces are very close to actual practical engineering applications and presented in an accessible style. The book can serve as reference teaching material for senior undergraduates and postgraduates with space navigation related majors, while also providing essential information and guidance for research personnel and engineering technical personnel engaged in the development of GNC systems for spacecraft.

There are some serious concerns and critical questions about the on-going minority protesting in China, such as Tibetan monks' self-immolations, Muslims' suicide bombings, and Uyghur large-scale demonstrations. Why are minorities such as the Uyghur dissatisfied, when China is rising as a world power? What kind of struggle must they go through to maintain their identity, heritage, and rights? How does the government deal with this ethnic dissatisfaction and minority riots? And what is ethnic China's future in the 21st century? Ethnic China examines these issues from the perspective of Chinese-American scholars from fields such as economics, political science, criminal justice, law, anthropology, sociology, and education. The contributors introduce and explore the theory and practice of policy patterns, political systems, and social institutions by identifying key issues in Chinese government, society, and ethnic community contained within the larger framework of the international sphere.Their endeavors move beyond the existing scholarship and seek to spark new debates and proposed solutions while reflecting on established schools of history, religion, linguistics, and gender studies.

Microbial infections have been and continue to be a major threat to public health. China has a huge population, among which, microbial infections are of great concern. The Journal of Microbes and Infection, a nationwide journal in China with over 4000 subscriptions, publishes original research articles on microbes and infections in the Chinese language. This book contains selected research articles published in this journal from 2006 to 2007 that have been translated into English, and offers a glimpse of a broad range of microbial infections including the clinical and epidemiological aspects of various viral infections, current status of bacterial infections in hospitals, and severe cases of fungal infections. This book provides a rare opportunity for scientists and physicians abroad to see the completely original research data, rather than just the abstract, based on studies conducted in modern China. Articles on molecular biological and bioinformatic studies are also included. An overview of the recent research trend in medical microbiology and infectious diseases in China will be presented as well. Scientists and physicians working in the fields of virology, microbiology, immunology, epidemiology, vaccinology, and infectious diseases will find the articles in this book fascinating and relevant to their own research and practice.
