Advances in Filament Yarn Spinning of Textiles and Polymers reviews the different types of spinning techniques for synthetic polymer-based fibers, and issues such as their effect on fiber properties, including melt, dry, wet, and gel spinning.

Synthetic polymer-based fibers are used in a great variety of consumer and industrial textile applications ranging from clothing to home furnishings to surgical procedures. This book explores how a wide array of spinning techniques can be applied in the textile industry. Part one considers the fundamental structure and properties of fibers that determine their behavior during spinning. The book then discusses developments in technologies for manufacturing synthetic polymer films to produce different fibers with specialized properties. Part two focuses on spinning techniques, including the benefits and limitations of melt spinning and the use of gel spinning to produce high-strength and high-elastic fibers. These chapters focus specifically on developments in bi-component, bi-constituent, and electro-spinning, in particular the fabrication of nanocomposite fibers. The final chapters review integrated composite spinning of yarns and the principles of wet and dry spinning.

This collection is an important reference for a wide range of industrial textile technologists, including spinners, fabric and garment manufacturers, and students of textile technology. It is also of great interest for polymer scientists.

Why would a politically centralized state embark on the path of economic decentralization? This Element delves into the political origin of the puzzling economic decentralization in mainland China. The authors contend that the intra-elite conflicts between the authoritarian ruler and the ruling elites within the state prompted the ruler to pursue decentralization as a strategy to curb the influence wielded by the ruling elites. By examining the composition of the Chinese Communist Party's Central Committee, they find that the Cultural Revolution, fueled by elite conflicts, shifted the elite selectorate's composition from favoring central agencies to favoring local interests. Subsequent low turnover reinforced this shift, aligning elite incentives with decentralization policies and committing the Chinese leadership to a decentralized path in the 1980s. Additionally, Taiwan's economic liberalization under the Kuomintang's authoritarian rule provides further evidence of the link between ruling party elite composition and economic policy orientation.

Addressing the active and challenging field of spectral theory, this book develops the general theory of spectra of discrete structures, on graphs, simplicial complexes, and hypergraphs. In fact, hypergraphs have long been neglected in mathematical research, but because of the discovery of Laplace operators that can probe their structure, and their manifold applications from chemical reaction networks to social interactions, they have now become one of the most active areas of interdisciplinary research. The authors' analysis of spectra of discrete structures embeds intuitive and easily visualized examples, which are often quite subtle, within a general mathematical framework. They highlight novel research on Cheeger-type inequalities that connect spectral estimates with the geometry, more precisely the cohesion, of the underlying structure. Establishing mathematical foundations and demonstrating applications, this book will be of interest to graduate students and researchers in mathematics working on the spectral theory of operators on discrete structures.
