This book constructs a four-dimensional driving model for customer perception of cross-border e-commerce retail imports from a consumer perspective, and constructs a secondary indicator of the four-dimensional driving model for customer perception of cross-border e-commerce retail imports based on product and service theme attributes. It studies the competitive advantages of importing cross-border e-commerce from the perspectives of platform enterprises and users. At the same time, by constructing a research model for evaluating cross-border e-commerce policies, the book analyzes the...

Structure-Preserving Algorithms for Oscillatory Differential Equations describes a large number of highly effective and efficient structure-preserving algorithms for second-order oscillatory differential equations by using theoretical analysis and numerical validation. Structure-preserving algorithms for differential equations, especially for oscillatory differential equations, play an important role in the accurate simulation of oscillatory problems in applied sciences and engineering. The book discusses novel advances in the ARKN, ERKN, two-step ERKN, Falkner-type and...

The Chinese overseas now number 25 to 30 million, yet the 2,000-year history of Chinese attempts to venture abroad and the underlying values affecting that migration have never before been presented in a broad overview. Despite centuries of prohibition against leaving the land and traveling and settling overseas, the "earthbound" Chinese--first traders, then peasants and workers--eventually found new sources of livelihood abroad. The practice of sojourning, being always temporarily away from home, was the answer the Chinese overseas found to deal with imperial and orthodox concerns. Today...

A complex disease involves many etiological and risk factors operating at multiple levels molecular, cellular, organismal, and environmental. The incidence of such diseases as cancer, obesity, and diabetes are increasing in occurrence, urging us to think fundamentally and use a broader perspective to identify their connection and revolutionize treatments. The understanding of biological data derived from studying diseases can be enhanced by theories and mathematical models, which clarify the big picture and help to reveal the overarching mechanisms that govern complex biological phenomena....
