The differential quadrature hierarchical finite element method (DQHFEM) was proposed by Bo Liu. This method incorporated the advantages and the latest research achievements of the hierarchical finite element method (HFEM), the differential quadrature method (DQM) and the isogeometric analysis (IGA). The DQHFEM also overcame many limitations or difficulties of the three methods.This unique compendium systemically introduces the construction of various DQHFEM elements of commonly used geometric shapes like triangle, tetrahedrons, pyramids, etc. Abundant examples are also included such as statics and dynamics, isotropic materials and composites, linear and nonlinear problems, plates as well as shells and solid structures.This useful reference text focuses largely on numerical algorithms, but also introduces some latest advances on high order mesh generation, which often has been regarded as the major bottle neck for the wide application of high order FEM.

This book summarizes the highlights of our work on the bond polarizability approach to the intensity analysis. The topics covered include surface enhanced Raman scattering, Raman excited virtual states and Raman optical activity (ROA). The first chapter briefly introduces the Raman effect in a succinct but clear way. Chapter 2 deals with the normal mode analysis. This is a basic tool for our work. Chapter 3 introduces our proposed algorithm for the Raman intensity analysis. Chapter 4 heavily introduces the physical picture of Raman virtual states. Chapter 5 offers details so that the readers can have a comprehensive idea of Raman virtual states. Chapter 6 demonstrates how this bond polarizability algorithm is extended to ROA intensity analysis. Chapters 7 and 8 offer details on ROA, showing many findings on ROA mechanism that were not known or neglected before. Chapter 9 introduces our proposed classical treatment on ROA which, as combined with the results from the bond polarizability analysis, leads to a comprehensive physical picture for the Raman effect. In particular, this classical treatment unifies ROA and VCD (vibrational circular dichroism) on equal footing. In each section, Comments summarize the key ideas and their evaluation. This will help the readers to capture the core ideas of the presentations.

Evidence-based Clinical Chinese Medicine: Vol. 1 Chronic Obstructive Pulmonary Disease provides a "whole evidence" analysis of the Chinese medicine management of chronic obstructive pulmonary disease (COPD).

The book investigates the impact of the market-oriented economic reform in China on a unique aspect of the labor market outcomes - individuals' access to different employment sectors, that is, the state and collective sector, the private sector, and the sector of family contract farming in the 1990s. Using the longitudinal data of China Health and Nutrition Survey, the author finds that the access to different employment sectors is not equally distributed among Chinese workers during the market transition. And the hierarchy of employment sectors is reproduced through the procedure that assorts individual workers to different employment sectors. In addition to achieved characteristics such as human capital, ascribed characteristics such as family background and gender are important factors in understanding the procedure of social stratification in the reform era. The book will be of value to social scientists interested in the market transition of socialist societies in general and the social transformation of contemporary China in particular.
