The ever-increasing complexity of on-chip interconnection poses great challenges for the architecture of conventional system-on-chip(SoC) in semiconductor industry. The rapid development of process technology enables the creation of stacked 3-dimensional(3 D) SoC by means of through-silicon-via(TSV). Stacked 3 D SoC testing consists of two major issues, test architecture optimization and test scheduling. This paper proposed game theory based optimization of test scheduling and test architecture to achieve win-win result as well as individual rationality for each player in a game. Game theory helps to achieve equilibrium between two correlated sides to find an optimal solution. Experimental results on handcrafted 3 D SoCs built from ITC'2 benchmarks demonstrate that the proposed approach achieves comparable or better test times at negligible computing time.

晚三叠世卡尼期全球古气候发生明显转变,全球降水量增加,海水温度上升了6~8℃,大量陆源碎屑物质输入海洋,导致海洋中出现碳酸盐生产危机。北秦岭南召盆地太山庙组可能记录了卡尼期洪水事件。目的为精确限定太山庙组沉积时代,凸显其地质意义,方法采用激光剥蚀电感耦合等离子体质谱法(LA-ICP-MS)对太山庙组下部凝灰岩进行锆石U-Pb同位素定年分析。结果结果表明:凝灰岩锆石颗粒呈粒状、短柱状,无磨圆;阴极发光图像显示振荡环带结构明显;根据阴极发光图像和Th/U,认为太山庙组下部凝灰岩中18颗锆石均为火山来源,剔除轻稀土富集的锆石后,选择其中15颗锆石进行计算,得到其加权平均年龄为(241.4±1.3)Ma(1σ;MSWD=0.27),代表凝灰岩中锆石的结晶年龄;结合前人研究成果,计算出太山庙组下部平均沉积速率为20.6 m/Ma,太山庙组底界年龄约246 Ma,因此,太山庙组至少自中三叠世安尼期就开始沉积,至晚三叠世卡尼期末结束;根据南召盆地遗迹化石组合演化规律和植物孢粉变化,认为太山庙组沉积时期古气候发生了明显转变,由干旱炎热气候转变为温暖、湿润气候。结论研究结果对北秦岭南召盆地三叠纪地层划分产生了新认识,有助于研究探讨南召盆地对卡尼期洪水事件的沉积响应。

A series of Ce-doped MnOx/TiO2 catalysts were prepared by impregnation method and used for catalytic oxidation of NO in the presence of excess O2. The sample with the Ce doping concentration of Ce/Mn=l/3 and calcined at 300 ℃ shows a superior activity for NO oxidation to NO2. On Ce（1）Mn（3）Ti catalyst, 58% NO conversion was obtained at 200 ℃ and 85% NO conversion at 250 ℃ with a GHSV of 41000 h-1, which was much higher than that over MnOx/TiO2 catalyst （48% at 250 ℃）. Characterization results implied that the higher activity of Ce（1）Mn（3）Ti could be attributed to the enrichment of well-dispersed MnO2 on the surface and the abundance of Mn3＋ and Zi3＋ species. The addition of Ce into MnO2/TiO2 could improve oxygen storage capacity and facilitate oxygen mobility of the catalyst as shown by PL and ESR, so that its activity for NO oxidation could be enhanced. The effect of H2O and SO2 on the catalyst activity was also investigated.

The bioeffects of silica nanoparticles (SiNP), phosphorylate-terminated nanoparticles (PO4- NP) and amino-terminated nanoparticles (NH2NP) on HaCaT cell line have been studied in this paper. The effects of the three kinds of functionalized silica nanoparticles on adherence, proliferation and cycle of HaCaT cells have been investigated. And the cel- lular uptake of the three kinds of functionalized silica nanoparticles by HaCaT cells has also been exam- ined. Results indicated that the bioeffects of the three kinds of functionalized nanoparticles on HaCaT cells were concentration-dependent. And the three kinds of functionalized nanoparticles all exhibited well bio- compatibility if the concentration was below 0.2 μg/μL. While the cytotoxicities of the three kinds of function- alized nanoparticles on HaCaT cells would increase with the increasing of nanoparticles concentration, and the following order was observed: NH2NP > SiNP > PO4NP. In addition, the quantity and rapidity of cellular uptake of nanoparticles by HaCaT cells were diverse due to the different functional groups. Under the same conditions, NH2NP was most and fast internalized by HaCaT cells, followed by SiNP, and PO4NP was the least and slowest. These results provided theoretical foundation for the safe applica- tion and further modification of silica nanoparticles, which could broaden the application of silica nano- particles in biomedicine.

Despite the use of many types of chemotherapies for pancreatic cancer, optimal efficacy has not been obtained so far. Pancreatic cancer shows a high incidence of TP53 mutations, inactivating its tumor suppressor activity. In this study, we identified sodium cantharidinate as a novel, potential anti-pancreatic cancer agent that activates p53 function. Sodium cantharidinate reduced the viability of pancreatic cancer cells, including the human primary pancreatic cancer cells, PANC-1, As PC-1, SW1990 and BXPC-3, in a dose-dependent manner. Sodium cantharidinate induced apoptosis and DNA damage of pancreatic cancer cells. Furthermore, proteome-wide sequencing analysis detected a marked perturbation in p53 signaling pathway on PANC-1 cells upon sodium cantharidinate. Consistent with the previous results, sodium cantharidinate treatment decreased Bcl-2 and mitochondrial cytochrome-c protein expression, as well as phosphorylation of MDM2;meanwhile, it increased the levels of cleaved-caspase-3,cleaved-caspase-9, cleaved-PARP, Bax, and phosphorylated p53, thus inducing the apoptosis of pancreatic cancer cells. The p53-activating effect of sodium cantharidinate was strongly abrogated by treatment with TP53-targeting sh RNA. Moreover, sodium cantharidinate inhibited neoplasm growth via the JAK2-STAT3 pathway, which was inhibited by sh RNA-TP53 and triggered by combination with gemcitabine. Combination therapy indicated that sodium cantharidinate and gemcitabine synergistically reduced ex vivo and in vivo growth of pancreatic neoplasm. Further docking studies revealed the different binding fates of sodium cantharidinate to activate wild-type p53 function. Thus, sodium cantharidinate could be a potential agent with promising anti-pancreatic cancer efficacy.

A novel all-solid-state, coaxial, fiber-shaped asymmetric supercapacitor has been fabricated by wrapping a conducting carbon paper on a MnO2-modified nanoporous gold wire. This energy wire exhibits high capacitance of 12 ***^-2 and energy density of 5.4 μ***^-2 with excellent cycling stability. Hierarchical nanostructures and coaxial architectural design facilitate effective contacts between the two core@sheath electrodes and active layers with high flexibility and high performance. This work provides the first example of coaxial fiber- shaped asymmetric supercapacitors with an operation voltage of 1.8 V, and holds great potential for future flexible electronic devices.
