Seifert fiberings extend the notion of fiber bundle mappings by allowing some of the fibers to be singular. Away from the singular fibers, the fibering is an ordinary bundle with fiber a fixed homogeneous space. The singular fibers are quotients of this homogeneous space by distinguished groups of homeomorphisms. These fiberings are ubiquitous and important in mathematics. This book describes in a unified way their structure, how they arise, and how they are classified and used in applications. Manifolds possessing such fiber structures are discussed and range from the classical three-dimensional Seifert manifolds to higher dimensional analogues encompassing, for example, flat manifolds, infra-nil-manifolds, space forms, and their moduli spaces. The necessary tools not covered in basic graduate courses are treated in considerable detail. These include transformation groups, cohomology of groups, and needed Lie theory. Inclusion of the Bieberbach theorems, existence, uniqueness, and rigidity of Seifert fiberings, aspherical manifolds, symmetric spaces, toral rank of spherical space forms, equivariant cohomology, polynomial structures on solv-manifolds, fixed point theory, and other examples, exercises and applications attest to the breadth of these fiberings. This is the first time the scattered literature on singular fiberings is brought together in a unified approach. The new methods and tools employed should be valuable to researchers and students interested in geometry and topology.

It has a small number of 1505 speakers who claim themselves to be Sadu though officially the group is taken as part of the Bai people. It differs not only from Bai, however, but also from the southern dialects of the Yiish branch spoken by the neighboring communities, such as Nisu, Nasu, and Shansu.
Moore's Law predicts that the degree of microprocessor integration of circuits would double every 18 months in DRAM. Although the scaling of microelectronic circuit elements still follows Moore's Law, the unit density of power consumption becomes unacceptable. Therefore, on one hand, people develop continuously the microelectronic technology. On the other, people consider the developing road after Moore's rule is broken. This book introduces theories and experiments of quantum transport and intends to provide foundations of semiconductor micro- and nano electronics for after the Moore age.

Single-molecule studies constitute a distinguishable category of focused - search in nanoscience and nanotechnology. This book is dedicated to the - troduction of recent advances on single-molecule studies. It will be illustrated that studying single molecules is both intellectually and technologically ch- lenging, and also o?ers vast potential in opening up new scienti?c frontiers. We wish to present the readers with several di?erent techniques for studying single molecules, such as electron-tunneling methods, interaction-force m- surement techniques, optical spectroscopy, plus a number of directions where further progress could be pursued. We hope the work may assist the readers, especially graduate students and those who wish to explore single molecules, to become familiarized with the pace of the progress in this ?eld and the relevant primary techniques. Due to limitation of space, we are not able to elaborate on the technical details of all of the experimental methods that are vital in single molecule studies, so introductions to only selected experimental methods are touched in the context. Since the technical details and theoretical analysis of these techniqueshavealreadybeenthoroughlycoveredinmanyliteratures,weonly provide introductions to the basic principles of the detection techniques here, and focus on their experimental achievements in the area of single-molecule studies. These techniques have proven to be highly e?ective when indep- dently used. The combinationof those techniques could lead to further - vances in the detection capabilities.
This book focuses on security science and technology, data and information security, and mobile and network security for space-air-ground integrated networks (SAGINs). SAGIN are expected to play an increasingly important role in providing real-time, flexible, and integrated communication and data transmission services in an efficient manner. Today, SAGINs have been widely developed for a range of applications in navigation, environmental monitoring, traffic management, counter-terrorism, etc. However, security becomes a major concern, since the satellites, spacecrafts, and aircrafts are susceptible to a variety of traditional/specific network-based attacks, including eavesdropping, session hijacking, and illegal access. In this book, we review the theoretical foundations of SAGIN security. We also address a range of related security threats and provide cutting-edge solutions in the aspect of ground network security, airborne network security, space network security, and provide future trends in SAGIN security. The book goes from an introduction to the topic’s background, to a description of the basic theory, and then to cutting-edge technologies, making it suitable for readers at all levels including professional researchers and beginners. To gain the most from the book, readers should have taken prior courses in information theory, cryptography, network security, etc.
One hundred million betrothal gifts, she was forced to marry a tyrant who was said to have been disfigured.

For 1,300 years, Chinese calligraphy was based on the elegant art of Wang Xizhi (A.D. 303–361). But the seventeenth-century emergence of a style modeled on the rough, broken epigraphs of ancient bronzes and stone artifacts brought a revolution in calligraphic taste. By the eighteenth century, this led to the formation of the stele school of calligraphy, which continues to shape Chinese calligraphy today. A dominant force in this school was the eminent calligrapher and art theorist Fu Shan (1607–1685). Because his work spans the late Ming–early Qing divide, it is an ideal prism through which to view the transformation in calligraphy. Rather than seek a single explanation for the change in calligraphic taste, the author demonstrates and analyzes the heterogeneity of the cultural, social, and political processes behind it. Among other subjects, the book covers the late Ming interaction between high and low culture; the role of publishing; the Ming loyalist response to the Qing; and early Qing changes in intellectual discourse. In addition to the usual approach of art historians, it adopts the theoretical perspectives of such fields as material culture, print culture, and social and intellectual history.
Large Dimensional Factor Analysis provides a survey of the main theoretical results for large dimensional factor models, emphasizing results that have implications for empirical work. The authors focus on the development of the static factor models and on the use of estimated factors in subsequent estimation and inference. Large Dimensional Factor Analysis discusses how to determine the number of factors, how to conduct inference when estimated factors are used in regressions, how to assess the adequacy pf observed variables as proxies for latent factors, how to exploit the estimated factors to test unit root tests and common trends, and how to estimate panel cointegration models.
After impressive growth of about 10% per annum for three decades, China's visible signs of economic slowdown since 2008 have been subject to much contention. What causes the deceleration? What should we expect in an era of China's 6% growth? This book answers these questions in three parts. Although it is widely accepted that China can hardly continue its high-speed growth model, estimations for its future growth potential differ greatly. The first part of this book predicts China's growth to 2050, which considers both cross-country historical experiences and China's own demographic structure and employment participation features. In the second part, the book offers a comprehensive estimation of China's national and provincial total factor productivity (TFP) over the period of 1978 to 2014 based on comparable data. It then analyzes the causes of China's economic slowdown from a productivity point of view. Finally, this book correspondingly outlines policy recommendations, including supply-side structural reform and macroeconomic policy frameworks, to effectively address the issue of decline in both labor and labor productivity growth. This book will attract scholars and students of economics and China's economic studies.
Cooperative Control Design: A Systematic, Passivity-Based Approach discusses multi-agent coordination problems, including formation control, attitude coordination, and synchronization. The goal of the book is to introduce passivity as a design tool for multi-agent systems, to provide exemplary work using this tool, and to illustrate its advantages in designing robust cooperative control algorithms. The discussion begins with an introduction to passivity and demonstrates how passivity can be used as a design tool for motion coordination. Followed by the case of adaptive redesigns for reference velocity recovery while describing a basic design, a modified design and the parameter convergence problem. Formation control is presented as it relates to relative distance control and relative position control. The coverage is concluded with a comprehensive discussion of agreement and the synchronization problem with an example using attitude coordination.
Symbolic dynamics is a coarse-grained description of dynamics. It provides a rigorous way to understand the global systematics of periodic and chaotic motion in a system. In the last decade it has been applied to nonlinear systems described by one- and two-dimensional maps as well as by ordinary differential equations. This book will help practitioners in nonlinear science and engineering to master that powerful tool.
In this ambitious volume, Yunfei Bai delves into the creative adaptations of classical Sanskrit, Chinese, and Tibetan literary texts by four renowned nineteenth- and early twentieth-century authors in France and Argentina: Theophile Gautier, Stephane Mallarme, Victor Segalen, and Jorge Luis Borges. Without any knowledge of the source languages, the authors crafted their own French and Spanish retellings based on received translations of these Asian works. Rewriting the Orient not only explores the so far untapped translation-rewriting continuum to trace the pivotal role of Orientalism in the formation of a singular corpus of world literature that goes beyond the Anglophone canon, but also sheds light on a wide range of innovative discursive strategies that readily challenge traditional notions of cultural appropriation.
This book is a monograph on chaos in dissipative systems written for those working in the physical sciences.
