1Preparation and characterization of Al/B/Fe_2O_3 nanothermites显示文摘A sol-gel synthetic approach combined with an ultrasonic method was utilized to prepare Al/B/Fe2O3 nanothermites.The structure and properties of the prepared nanothermites were characterized by thermogravimetric analysis,differential scanning calorimetry,scanning electron microscopy,X-ray diffraction,and an impact sensitivity test.The results verified that the nano-aluminum and the micro-boron were uniformly dispersed in the pores of the iron oxide gel.The heat of the prepared Al/B/Fe2O3 nanothermites was 1.3 times that of the simple physically mixed sample.In addition,the heat of the combustion test showed that these materials were indeed energetic.Small-scale safe experiments also showed that the prepared materials through sol-gel were relatively insensitive to standard impact.SHEN LianHua LI GuoPing LUO YunJun GAO Kun GE Zhen 2014Science China Chemistry2014,57,6:6
2Apparent diffusion coefficient evaluation for secondary changes in the cerebellum of rats after middle cerebral artery occlusion显示文摘Supratentorial cerebral infarction can cause functional inhibition of remote regions such as the cerebellum,which may be relevant to diaschisis.This phenomenon is often analyzed using positron emission tomography and single photon emission CT.However,these methods are expensive and radioactive.Thus,the present study quantified the changes of infarction core and remote regions after unilateral middle cerebral artery occlusion using apparent diffusion coefficient values.Diffusion-weighted imaging showed that the area of infarction core gradually increased to involve the cerebral cortex with increasing infarction time.Diffusion weighted imaging signals were initially increased and then stabilized by 24 hours.With increasing infarction time,the apparent diffusion coefficient value in the infarction core and remote bilateral cerebellum both gradually decreased,and then slightly increased 3–24 hours after infarction.Apparent diffusion coefficient values at remote regions(cerebellum)varied along with the change of supratentorial infarction core,suggesting that the phenomenon of diaschisis existed at the remote regions.Thus,apparent diffusion coefficient values and diffusion weighted imaging can be used to detect early diaschisis.Yunjun Yang Lingyun Gao Jun Fu Jun Zhang Yuxin Li Bo Yin Weijian Chen Daoying Geng 2013Neural Regeneration Research2013,8,31:3

17Efficient Evaluation of Monitoring Top-t Most Influential Places显示文摘The continuous top-t most influential place (CTtMIP) query is defined formally and solved efficiently in this paper. A CTtMIP query continuously monitors the t places with the maximum influence from the set of places, where the influence of a place is defined as the number of its bichromatic reverse k nearest neighbors (BRkNNs). Two new metrics and their corresponding rules are introduced to shrink the search region and reduce the candidates of BRkNNs checked. Extensive experiments confirm that our proposed approach outperforms the state-of-the-art competitor significantly.LI Zhicheng GAO Yunjun LU Yansheng 2012Wuhan University Journal of Natural Sciences2012,17,1:0
