Foreign Direct Investment (FDI) in China over the past 25 years has increased faster than in any other economy. The net impact upon the Chinese economy appears to be highly favorable. A major portion of that FDI has been made by overseas Chinese, with assistance from a Mainland Chinese ministry...

The varying coefficient model is an important class of nonparametric statistical model, which allows us to examine how the effects of covariates vary with exposure variables. When the number of covariates is large, the issue of variable selection arises. In this article, we propose and...

In this paper, a double-acting thermoacoustic Stirling electric generator is proposed as a new device capable of converting external heat into electric power. In the system, at least three thermoacoustic Stirling heat engines and three linear alternators are used to build a multiple-cylinder...
