训练强度对运动员免疫系统功能的影响

运动员长时间大强度训练会造成免疫系统机能短暂改变,导致一段时间的免疫抑制.重复进行高强度训练,缺少足够的恢复时间,会明显增加上呼吸道感染的几率.高强度训练对免疫系统的影响可以通过唾液中免疫球蛋白A(IgA)浓度下降发现,唾液中IgA是检测运动员是否有感染危险的有效指标.高强度运动可以被认为是肌体的应激反应,细胞因子(如IL-6)是引发这种应答的关键因素.摄入糖饮料可以减小高强度训练对荷尔蒙和免疫系统的影响.     

运动员人格特征与赛前焦虑、心境状态的相关关系

采用测试研究方法，分析了人格特征与运动员的竞赛焦虑和心境状态的相关关系。结果表明，不同人格特征运动员之间在比赛期间存在显著的竞赛焦虑和心境状态差异；比赛期间躯体焦虑比认知焦虑更能影响运动员的潜能发挥；心境状态是运动员竞赛焦虑的有效预测因子。

The more multidisciplinary the better? – The prevalence and interdisciplinarity of research collaborations in multidisciplinary institutions

Scientific research is increasingly relying on collaborations to address complex real-world problems. Many researchers, policymakers, and administrators consider a multidisciplinary environment an important factor for fostering research collaborations, especially interdisciplinary ones that involve researchers from different disciplines. However, it remains unknown whether a higher level of multidisciplinarity within an academic institution is associated with internal collaborations that are more prevalent and more interdisciplinary. Analyzing 90,000 publications by 2500 faculty members in over 100 academic institutions from three multidisciplinary areas, information, public policy, and neuroscience, we investigated the connection between multidisciplinarity and research collaborations. Based on social network analysis and text mining, our analysis suggests that more multidisciplinary institutions are not necessarily more collaborative, although they do feature collaborations that are more interdisciplinary. Our findings provide implications for academic administrators and policymakers to promote research collaborations and interdisciplinarity in academic institutions.

高地震烈度区进水塔结构抗震分析

针对位于强震区软岩地基上的高耸进水塔结构,采用动力分析中的振型分解反应谱法,分析塔群的振型规律,对比分析在地震动峰值加速度由0.3 g提高到0.4 g的情况下,结构位移、应力和内力的变化情况。结果表明:塔顶位移和塔体应力均有较大幅度提高,需采用加固措施。     

Hybrid ants-like search algorithms for P2P media streaming distribution in ad hoc networks

Media streaming delivery in wireless ad hoc networks is challenging due to the stringent resource restrictions,po-tential high loss rate and the decentralized architecture. To support long and high-quality streams,one viable approach is that a media stream is partitioned into segments,and then the segments are replicated in a network and served in a peer-to-peer(P2P) fashion. However,the searching strategy for segments is one key problem with the approach. This paper proposes a hybrid ants-like search algorithm(HASA) for P2P media streaming distribution in ad hoc networks. It takes the advantages of random walks and ants-like algorithms for searching in unstructured P2P networks,such as low transmitting latency,less jitter times,and low unnecessary traffic. We quantify the performance of our scheme in terms of response time,jitter times,and network messages for media streaming distribution. Simulation results showed that it can effectively improve the search efficiency for P2P media streaming distribution in ad hoc networks.
