Univariate analysis indicated on an excess mortality among women(hazard ratio(HR) 1.44,95% CI 1.24～1.67, P <0.01),which disappeared after adjustment for age, smoking, co-morbidity, previous vascular disease, diabetes, hypertention, and social deprivation(HR1.01,95% CI 0.87～1.19, P >0.05).
On the institutional defect and its correction of venture capital in China
With the emergence of Knowledge Economy, venture capital is playing a more and more important role in the high and new technology industry in China.
The situation and problems of venture investment in China are analyzed in this paper which pointed out some problems that hinder the process of venture investment, and also, gave some suggestions to promote the development of venture capital.
Being financed by venture capital is the prime economic basis of the enterprises of the New Economy.
Investments by venture capitalists in innovative enterprises are planned with regard to the end or the ?exit".
Hazard function and characterizations on distribution tails of nonnegative random variables
In this paper we pay special attention to the hazard rate function re(x) of Fe(x), which is also called the equilibrium hazard rate (E.H.R.) of F(x).
All these were analyzed in 105 cases along with the follow-up data and tested by log rank and COX hazard proportional model.
The COX hazard proportional model revealed that advanced clinical stage (P = 0.001), large tumor size (P = 0.001), a high mitotic index (P = 0.002) and the high risk grade (P = 0.018) indicated a poorer prognosis in gastric GIST.
A possibility is considered for predicting the radiation hazard onboard orbital stations upon the appearance of solar proton events using dosimeter data from a geosynchronous orbit.
