育龄妇女早期自然流产危险因素的Logistic回归分析

目的:调查育龄妇女早期自然流产的危险因素,降低和预防自然流产的发生。方法:采用病例对照研究,用单因素和多因素Logistic回归分析探讨早期自然流产的危险因素。结果:单因素分析显示,男女双方学历、男女双方年龄、胎次与早期自然流产相关;多因素Logistic回归分析显示,女方学历、规律的妇科检查、男方年龄与早期自然流产相关。结论:女方学历、男方年龄是引起育龄妇女早期自然流产的危险因素,规律的妇科检查可降低自然流产的发生。

GIMC architecture for linear systems with a single I/O delay

A new feedback controller architecture is presented for linear systems with a single I/O delay in the generalized internal model control (GIMC) framework. According to the doubly coprime factorization of these systems, traditional GIMC strategy is extended to linear systems with a single I/O delay. The distinguished feature of the control system architecture is that high tracking performance and good external disturbance rejection could be done separately by a nominal Smith predictor part and a finite dimensional conditional controller. First, a nominal Smith predictor part could be designed to deal with command tracking performance. Second, according to the left coprime factorization of the nominal controller, a finite dimensional conditional controller could be considered for external disturbance rejection, when the controlled plant should be assumed to be a square one. Finally, a simple design example is illustrated the effectiveness of the presented method.Finally, a simple design example is illustrated the effectiveness of the presented method.     

Patent collaboration and international knowledge flow

In this paper, we provide an empirical analysis of evolving knowledge networks of successful patent collaboration at national level in 1980s, 1990s, and 2000s. All countries are classified into main knowledge creators (Organisation for Economic Co-operation and Development (OECD) group) and main knowledge users (non-OECD group) in order to distinguish specific characteristics of knowledge interactions within groups and between groups. The analyses are carried out from four aspects, i.e., the overall distribution of knowledge interactions among countries, the countries’ ability to inhabit and facilitate the knowledge flows among others with the help of flow betweenness measures, the countries’ bridgeness between two groups with the recently developed Q-measures, and the most important bilateral knowledge interactions. Results show that although most of the international knowledge interactions still take place within the OECD group, the non-OECD countries have improved their performance significantly. They participate much more in international patenting and collaborations and play much more important roles in facilitating knowledge interactions among others. Among them, China and Taiwan are two most dazzling new stars according to their performance in international knowledge interactions. Considering together with their rapidly improved world competitiveness, the findings indicate that the wide and deep participation in international knowledge interactions may have great contribution to the economic competitiveness.
