By examining the origin and growth dynamics of two generations of high-tech startups in China's information technology sectors, this study presents empirical research on how Chinese technology startup companies, despite their lack of many of the basic elements that are usually necessary for a...

Microvalve is one of the most important components in microfluidic systems and micropumps. In this paper, three-dimensional incompressible flow through a Tesla-type microvalve is simulated using FLUENT computational fluid dynamic package. The flow is laminar and SIMPLE algorithm is used. The...

The identification and estimation of a semiparametric simultaneous equation model with selectivity have been considered. The identification of structural parameters from reduced form parameters in the semiparametric model requires stronger conditions than the usual rank condition in the...
