Grain boundary engineering（GBE） is a practice of improving resistance to grain boundary failure of the material through increasing the proportion of low Σ coincidence site lattice（CSL） grain boundaries（special grain boundaries） in the grain boundary character distribution（GBCD）. The GBCD in a cold rolled and annealed Fe-18Cr-18Mn-0.63N high-nitrogen austenitic stainless steel was analyzed by electron back scatter difraction（EBSD）. The results show that the optimization process of GBE in the conventional austenitic stainless steel cannot be well applied to this high-nitrogen austenitic stainless steel. The percentage of low ΣCSL grain boundaries could increase from 47.3% for the solid solution treated high-nitrogen austenitic stainless steel specimen to 82.0% for the specimen after 5% cold rolling reduction and then annealing at 1423 K for 10 *** special boundaries of high proportion efectively interrupt the connectivity of conventional high angle grain boundary network and thus achieve the GBCD optimization for the high-nitrogen austenitic stainless steel.

On 23 July 2009, a catastrophic debris flows were triggered by heavy rainfall in Xiangshui gully, Kangding county, southwestern China. This debris flow originating shortly after a rainstorm with an intensity of 28 mm per hour transported a total volume of more than 480×103 m3 debris, depositing the poorly sorted sediment including boulders up to 2-3 m in diameter both onto an existing debris fans and into the river. Our primary objective for this study was to analyze the characteristics of the triggering rainfall and the debris supply conditions, and to estimate debris-flow volume, mean velocity, and discharge. A comparison with adjacent rain-gage records indicates that debris flows in this setting can be produced in response to as little as 17 mm/hour or 3.5 mm/10-minute of rainfall intensity with relatively lower amount of cumulative antecedent rainfall. The field measurement and the interpretation of the Worldview image indicate that abundant landslides occurred on steep slopes within areas underlain by highly weathered granite. Using empirical equations that combine flow depth and channel slope, the mean velocity and discharge of the debris flow were estimated to be 9.2 m/s and 2150 m3/s, respectively. The results contribute to a better understanding of the conditions leading to catastrophic debris flows.

Using conventional imaging modalities, it is difficult to detect recurrent lesions in prostate cancer patients who have undergone biochemical relapse, especially in patients with low prostate-specific antigen （PSA） levels. We retrospectively reviewed the files of fifty patients with histopathologically confirmed prostate cancer who underwent 99mTc-labeled prostate-specific membrane antigen （PSMA） single-photon emission computed tomography （SPECT）/computed tomography （CT）, magnetic resonance imaging （MRI）, and bone scan within a 30-day period. PSMA-SPECT/CT indicated metastatic lesions in 39 patients and had a higher detection rate （78.0%） than bone scan （34.0%） or MRI （40.0%）. The diagnostic efficiency of PSMA-SPECT/CT imaging for bone and lymph node metastases （50.0% and 42.0%） was better than bone scan （34.0% and 0.0%） or MRI （24.0% and 20.0%）. PSMA-SPECT/CT provided a higher detection rate at serum PSA levels of 〈1 ng ml-1, 1-4 ng ml-1, 4-10 ng ml-1, and 〉10 ng ml-1. No correlation was found between Gleason score, PSA level, and the tracer tumor/background ratio of metastatic lesions. With the aid of PSMA-SPECT/CT imaging, the therapeutic strategy was changed for 31 patients, and this may have enhanced their clinical outcome. In conclusion, PSMA-SPECT/CT imaging could detect more metastatic lesions and achieve a higher detection rate than conventional imaging modalities at different serum PSA levels in prostate cancer patients who had undergone biochemical relapse.

体育史学史作为一门新兴交叉学科,主要研究体育史学自身发展的历史。我国体育史学史研究涉及众多学科门类,形成了以体育学和历史学为主线,以哲学、经济学、管理学、社会学等学科为辅助的综合化研究理路。论及中国体育史学史研究的中心论题,这既来源于对我国体育史发展不平衡的归因分析,也涉及体育史学史建构的基本问题。我国体育有没有自身运动发展的历史脉络,关键在于探讨体育史学史研究命题缘起问题;我国体育的实践禀性是否拥有史学的居所,重点在于围绕中国体育史学史归属作出研判;当前体育学科发展史能否代表体育史全部,任务在于观瞻中国体育史学史的发展前景。

为构建基于无线传感器网络的铁路防灾安全监控系统,在门限敏感的节能型网络协议(TEEN)基础上,提出1种安全优先门限敏感分簇路由协议(SPTC)。确定SPTC的网络架构,基于能量计算公式设计簇头分布算法及簇头和副簇头选举算法,以及路由建立步骤和数据采集流程。在协议中定义副簇头,保证数据路由的可靠性及数据自身传输的安全,提高协议的安全性;在汇聚节点(SN)附近区域布置更小规模的簇,在兼顾剩余能量与节点距离的准则下选择最佳的簇头节点,以提高协议的节能性。采用OMNeT++网络仿真工具对SPTC进行了建模仿真。仿真结果表明:当网络工作了10 000s时,低能量节点数量比低功耗自适应聚类层次协议(LEACH)减少了60%;当灾害数据采集概率为0.5%时,基于SPTC协议的网络检测周期是基于LEACH的1.7倍。
