In survival analysis, the primary goal is to monitor several entities and model the occurrence of a particular event of interest. In such applications, it is quite often the case that the event of interest may not always be observed during the study period and this gives rise to the problem of censoring which cannot be easily handled in the standard regression approaches. In addition, obtaining sufficient...
In this paper, we focus on the problem of analyzing the operating performance of insurance companies, and this problem is crucial for modern financial industry development. Index system for evaluating operating performance of insurance companies is made up of four parts: 1) Profitability, 2) Solvency, 3) Capital adequacy and 4) Management ability. Main idea of this paper is to introduce DEA model...
Strategic human capital as the unique resources brings competitive advantages for enterprises, which is unquestionable. Because of different strategies at business level, strategic human capital characteristics are different. This paper, firstly, through exploratory factor analysis surveys the strategies at the business layer of 435 enterprises, two different types of enterprises under the cost leading...
The prevalence of Avian influenza viruses (AIV) in poultry have become highly in many places. AIV mainly cause uncontrolled systemic inflammatory response, led to pulmonary infection. We use Syngeneic marrow stem cells (MSCs) injected through the caudal vein of mice 30 min after H9N2 AIV intranasally treaded. Seven days later, we observed the mortality, absolute and relative lung weight, PaO2 and...
Workflow is a promising technology for realizing process-oriented information systems. However, the traditional workflow management systems are designed to handle the static business processes. How to model dynamic changes of workflow is one of hotspots of current research. The unified modeling language (UML) and polychromatic sets (PS) theory are introduced and their advantages and disadvantages...
As SNMP management system has some weaknesses due to its built-in functional limitation, NETCONF, with XML as its data encoding scheme, is viewed as a promising solution for future network configuration management. To make NETCONF interoperable and capable of manipulating data in a standardized fashion, an extensible data modeling language, YANG, was proposed to model data including configuration...
With rapid development of communication technology, the signal integrity is impacting the system performance much more than before. So either in the IC design or in the system design, it is very important to investigate negative timing analysis and its mathematical modeling in the high speed integrated circuit. In the paper, we introduce the origin of the negative timing script in the deep sub-micrometer...
