Background: Traditional Chinese sports and physical activities(PAs) have a long history and are practiced by millions of Chinese. However,relatively few systematic reviews of the scientific evidence for their health benefits, especially for older Chinese adults, have been *** acquisition: Between January and March 2016, a systematic search was conducted using the CNKI and Pub Med databases to identify studies published between 2000 and 2015. Studies were selected for review if they were designed specifically to evaluate the health benefits of traditional Chinese sports and PAs in adults aged 50 years and older in the Mainland of China. The studies included observational, uncontrolled,and randomized and controlled designs. Papers published without an English title or abstract were *** synthesis: The initial search identified a total of 229 studies. After removing duplicates and studies that did not meet the inclusion/exclusion criteria, 95 studies were selected for review. Special attention was given to studies of the most commonly practiced activities: Tai Ji Quan,Qigong, and Yangko exercises. A positive association between these types of exercise and health benefits was noted for healthy older adults and those with chronic diseases. Evidence on other types of activities was less clear due to the limited number of studies ***: There is promising evidence that traditional Chinese sports and PAs provide many health benefits for older Chinese adults. While additional scientifically rigorous research is warranted, promoting these traditional and culturally-based sports and PAs as forms of behavioral medicine in primary and secondary prevention of diseases among the aging Chinese population will help fulfill an urgent public health need.

Raman spectroscopy, with its specific ability to generate a unique fingerprint‐like spec-trum of certain substances, has attracted much attention in diagnosing the ageing degree of oil-paper insulation. In this study, the feature extraction and ageing diagnosis methods of oil-paper insulation Raman spectroscopy data are further studied. Based on the non‐linear analysis of Raman spectra of different ageing samples, kernel principal component analysis was applied to extract the spectral features, and the back‐propagation neural network was used to build a diagnosis model with high diagnostic accuracy. The results show that Raman spectroscopy combined with kernel principal component analysis and the back‐propagation neural network can diagnose the ageing state of oil-paper insu-lation, with a diagnostic accuracy of 91.43% (64/70). The proposed method provides an effective and feasible method for the ageing assessment of oil‐immersed electrical equipment.

In order to understand failure mechanisms of the tunnel excavated in the stratified rock masses in deep mine, the physical modeling experiment by using the large-scale model was carried out. The field case simulated in the experiment is a main connection tunnel located at depth of 1000 m in Qishan coal mine,Xuzhou mining district. Tunnel deformation was monitored by using strain gauges and a video camera simultaneously. Crack initiation and propagation process during the test were analyzed based on image analysis of the captured video photographs. At the same time, deformation process of the key monitoring points around the tunnel section is given by the monitored strain plots. Under the increasing external loads, crack initiation occurs firstly on the left wall of the tunnel, then on the immediate *** failure of the tunnel occurs as a result of the slippage of the rock layers along the interfaces.

In this paper, a Web service composition architecture based on structured P2P network is proposed. Semantics is used to achieve service accurately matching and user personality customization. Through Web service virtual mapping（WVM） association the fast computing of distributed service composition based on the service function is also implemented. The Web service composition architecture and distributed service composition algorithm proposed in this paper solve a series of existent problems in ser- vice discovery and composition in distributed environment, and provide a service composition result meeting user personality requirement. At the same time, they improve the efficiency of service composition calculation.

针对亭南煤矿深部软岩巷道底鼓大变形现象进行深入研究,综合采用现场工程地质调查、物化分析、数值模拟计算、现场测试等方法,分析得出西翼轨道巷道底鼓的复合型变形力学机制,提出采用"四控一措施"新技术将复合型变形力学机制转化为单一型变形力学机制,即将顶板、两帮、底角和底板四部位看作是相互联系的整体,综合控制各部位变形,并结合防治水措施,达到有效控制底鼓的目的。"四控"是指:在顶板施加锚杆并在关键部位施加锚索,有效降低来自顶板并传递至底板上的应力;通过施加底角锚杆,利用材料自身抗弯刚度,切断底板基角塑性滑移线;帮部打入锚杆,增强帮部岩体强度,减小发生底鼓底板宽度;施加反底拱对底板作用均匀一致的支护反力,形成封闭的支护体系。"一措施"是指:及时设置排水沟,避免排水不畅积水浸入底板造成膨胀性底鼓;对顶板及两帮围岩做喷浆处理切断裂隙水路径;巷道挖底后立即铺设干石灰粉垫层封闭底板围岩。工程实践表明,该项新技术在亭南矿有效地控制了软岩巷道底鼓变形。

Bipolar disorder(BD)is a debilitating psychiatric mood dis-order affecting approximately 1%-3%of the population worldwide(Merikangas,2007).Bipolar disorder is characterized by recurrent episodes of depression,hypomania,mania,or mixed states,and it has a poor outcome,with high rates of relapse,lingering residual symptoms,cognitive impairment,and functional impairment(Moreno et al.,2007)Although various etiopathological hypotheses concerning the disease have been reported,the pathophysiology underlying BD remains poody understood(Gawryluk and Young,2011).
