Upon deforming a metallic glass at low temperatures, shear tends to localize and this leads to a brittle behavior. However, in the high temperature, and particularly in the supercooled liquid region, homogeneous deformation begins to take place. A bulk amorphous Zr 10Al 5Ti 17.9Cu 14.6Ni alloy was observed to exhibit the Newtonian behavior at low strain rates but becomes non Newtonian at high strain rates in the supercooled liquid region. Structures of the amorphous material, both before and after deformation, were examined using X ray diffraction and high resolution electron microscopy. Results showed the presence of nanocrystallites in the deformed samples. Thus, the non Newtonian behavior is attributable to the concurrent crystallization of the amorphous structure during deformation. A mechanistic model is presented to interpret the observed non Newtonian result. A phenomenological approach is also used to develop the deformation map for bulk metallic glasses in the supercooled liquid region.

网络拓扑对电力网络的脆弱性和鲁棒性有重要影响,当前经典网络模型与实际电力网络有较大差异。基于电力网络本身的演化机理,对BA无标度网络模型进行扩展与改进,构造了一种复杂电力网络的时空演化模型。提出网络生长点的概念,将其定义为靠近网络中原有节点但并未被占据的位置。新节点加入时,其坐标从网络生长点中随机选择;已有节点与新节点连接的概率由该节点的度数和该节点与新节点间的物理距离共同决定。分析了该模型的统计学特性,通过美国西部电网、中国北方电网与几种典型网络模型在平均度数、聚类系数、特征路径长度和度分布曲线等方面的对比,验证了新模型能很好地反映电力网络的演化规律。

CeO_(2)is widely used as the nonradioactive surrogate fuel of UO_(2)when studying the irradiation performance of UO_(2).The evolution and characteristics of dislocation loops and bubbles in CeO_(2)foils were studied by in-situ transmission electron microscopy(TEM)observation during 400 ke V Kr^(+)&30 ke V H_(2)^(+)dual-beam synergetic irradiation and 400 ke V Kr^(+)single-beam irradiation at 1073 *** rotation of the habit plane of dislocation loops induced by above ion irradiation was found in the CeO_(2)for the first time,such as from[211]to[311]and then to[100].The rafted loops were first observed under Kr^(+)&H_(2)^(+)dual-beam synergetic irradiation,which not only had similar[111]direction,but also belonged to perfect dislocation loops(PDLs).The rafted loops were formed not only by the growth of loops that absorbed irradiation defects,but also by the combination of ***,this phenomenon of loop rafting was not obvious during Kr single-beam *** was first found that Kr^(+)irradiation induced the change of Burgers vectors of *** absorption of large PDLs to small PDLs was also *** average size and areal number density of dislocation loops and gas bubbles as a function of irradiation dose were constructed,which showed that the addition of H_(2)^(+)obviously affected the characteristics of dislocation loops and gas bubbles and the swelling of CeO_(2).

免疫性肝病是临床上难治性疾病,目前没有特效性药物,因此,研发新的有效干预药物,对防治免疫性肝病有重要的临床价值。为探讨青蒿琥酯（artesunate,Art）对免疫性肝损伤的保护作用,该研究采用不同质量浓度（27,54,108 mg·kg-1）Art灌胃小鼠连续7 d,然后尾静脉注射伴刀豆球蛋白A（concanavalin A,Con A）诱导小鼠肝损伤模型。于造模后8 h采血液和肝组织进行血清转氨酶（ALT,AST）、组织病变、炎性细胞因子以及NF-κB关键蛋白表达水平的检测。结果表明,与模型组相比,Art高浓度组显著降低了模型小鼠的肝指数、ALT和AST水平（P〈0.01）,组织病变也明显减轻,同时降低了促炎细胞因子TNF-α,IFN-γ,IL-6,IL-17的水平而增加了炎性抑制因子IL-10的表达（P〈0.05）,并呈现明显的剂量-效应关系。Western blot法检测结果显示108 mg·kg-1Art可显著抑制NF-κB关键蛋白p-p65和p-IκBα的表达（P〈0.01）。NF-κB特异阻断剂吡咯烷二硫代氨基甲酸酯（PDTC）也可显著抑制p-p65和p-IκBα表达并减轻肝损伤。以上结果说明Art主要通过抑制NF-κB信号通路而对Con A诱导的小鼠免疫性肝损伤发挥保护作用。该研究为青蒿琥酯用于自身免疫性肝损伤的防治提供了参考。

城市路网交叉口信号延误能精准反映出交叉口的运行效率和服务水平,传统延误估计方法在分析信号控制影响时往往需要多项输入数据,采集成本较大,因此大多研究仅从运动学角度出发分析延误特征,算法复杂且准确度低。为解决准确度和成本之间的矛盾,通过平移车辆时空轨迹计算延误估计所需参数,利用K-S检验和密度聚类算法得到交叉口信号配时,根据交通波理论得到交叉口受阻车辆总数,进而结合交叉口车流运动机理计算平均延误。最后通过VISSIM软件对单交叉口进行仿真,结果表明信号配时估计误差在5s内,直行和左转平均延误误差率分别在16%和26%内。说明方法能在数据信息单一的情况下保证延误准确度,具备有效性与实用价值。

　　In a study published in the current issue of the Journal of Geriatric cardiology, Ang and co-investigators used the highresolution 64-slice CT coronary angiography to detect coronary lesions in a group of patients with atypical angina.1 The clinical data of these patients were also used to calculate their risk according the Framingham and PROcaM scoring system.2,3 As the cohort is composed with a majority of low risk patients with atypical angina, only a small minority of the patients were classified as having medium and high risk. The results showed that MDCT uncovered 18% either significant lesions (＞50% stenosis) or calcifications (＞400Agatston units)in the low risk patients and 33% in the medium and high risk subgroups.……
