Research on consistency measurement and weight estimation approach of hybrid uncertain comparison matrix

The consistency measurement and weight estimation approach of the hybrid uncertain comparison matrix in the analytic hierarchy process （AHP） are studied. First, the decision-making satisfaction membership function is defined based on the decision making＇s allowable error. Then, the weight model based on the maximal satisfactory consistency idea is suggested, and the consistency index is put forward. Moreover, the weight distributing value model is developed to solve the decision making misleading problem since the multioptimization solutions in the former model. Finally, the weights are ranked based on the possibility degree approach to obtain the ultimate order.     

论林肯为维护国家统一做出的努力

在美国联邦面临分裂之时,林肯坚决强调国家主权不容侵害,领土不容分裂,维护国家统一不客质疑。在内战中,他着眼于大局,以国家的整体利益为重,为维护美利坚合众国的统一作出了重大的贡献,并表现出一种坚韧不拔的精神。统一则强,分裂则弱,美国内战的结果为美国成为世界强国奠定了坚实的基础。     

一种基于段的基音检测算法

作为语音信号处理领域一项基本、关键的技术,基音检测在语音信号处理中扮演着重要的角色,一直是语音信号处理的一个研究热点.首先对传统的基于短时自相关函数法的基音检测进行了研究;在此基础上提出了一种能同时检测一段语音信号基音周期的方法,有效地克服了传统基音检测算法只能检测一帧语音信号基音的缺点.进行了实验仿真,结果表明通过去野点,中值平滑等后处理的基于段的基音检测算法比传统的基于帧的基音检测算法具有更好的抗噪性.

Finding finer functions for partially characterized proteins by protein-protein interaction networks

Based on high-throughput data, numerous algorithms have been designed to find functions of novel proteins. However, the effectiveness of such algorithms is currently limited by some fundamental factors, including (1) the low a-priori probability of novel proteins participating in a detailed function; (2) the huge false data present in high-throughput datasets; (3) the incomplete data coverage of functional classes; (4) the abundant but heterogeneous negative samples for training the algorithms; and (5) the lack of detailed functional knowledge for training algorithms. Here, for partially characterized proteins, we suggest an approach to finding their finer functions based on protein interaction sub-networks or gene expression patterns, defined in function-specific subspaces. The proposed approach can lessen the above-mentioned problems by properly defining the prediction range and functionally filtering the noisy data, and thus can efficiently find proteins’ novel functions. For thousands of yeast and human proteins partially characterized, it is able to reliably find their finer functions (e.g., the translational functions) with more than 90% precision. The predicted finer functions are highly valuable both for guiding the follow-up wet-lab validation and for providing the necessary data for training algorithms to learn other proteins.     

GATS框架下我国劳务输出体制的完善

自然人移动作为GATS下第四种模式自身的特点,以及相关国际规则规定的不明确,使得自然人移动在国际贸易中壁垒重重.通过分析GATS下自然人移动的承诺情况,借鉴国外成功实践并吸收了国内外学者的最新研究成果,最后立足我国国情,建议我国应建立统一的劳务输出管理机构,制定专门的劳务输出法,改革签证制度,统一国内有关资格认证、许可的标准,并积极参与国际服务贸易规则的制订,以完善我国对外劳务输出体制.

改良低温麻醉阻断循环对肺超微结构影响的实验研究

本组用本地健康杂种犬10只,以改良低温麻醉体表降温方法将食道温度降至24～26℃时,然后阻断循环无体外循环下进行心内直视手术。术中分别在阻断前:阻断后及复苏后取肺组织进行光镜、电镜检查。实验结果表明,阻断时间在60分钟内,心脏跳停80分钟内无明显超微结构变化。而阻断时间65～85分钟,心脏跳停90～115分钟,肺组织的某些超微结构变化是可以复原的,这就为不用体外循环的肺脏手术安全时限提供了初步的理论依据。
