Strong metal-support interactions（SMSI）play significant roles in a series of heterogeneous catalysis,especially when involving reducible *** probe metal particle/reducible oxide interactions,ab initio molecular dynamics（AIMD）simulations based on density functional theory（DFT）were performed on a prototypical metal cluster（Au20）[1]supported on reducible oxides（rutile Ti O2（110））to implicitly account for finite temperature effects and the role of excess surface charge in the metal oxide[2].We find that the charge state of the Au particle is negative in a reducing chemical environment whereas in the presence of oxidizing species co-adsorbed to the oxide surface the cluster obtained a net positive *** the context of the well-known CO oxidation reaction,charge transfer facilitates the plasticization of Au20,which allows for a strong adsorbate-induced surface reconstruction upon addition of CO,leading to the formation of mobile Au-CO species on the *** charging/discharging of the cluster during the catalytic cycle of CO oxidation enhances and controls the amount of O2 adsorbed at oxide/cluster interface and strongly influences the energetics of all redox steps in catalytic conversions.A detailed comparison of the current findings with previous studies is presented,and generalities about the role of surface-adsorbate charge transfer for metal cluster/reducible oxide interactions are discussed.

Global existence of weak and strong solutions to the quasi-hydrostatic primitive equations is studied in this paper. This model, that derives from the full non-hydrostatic model for geophysical fluid dynamics in the zero-limit of the aspect ratio, is more realistic than the classical hydrostatic model, since the traditional approximation that consists in neglecting a part of the Coriolis force is relaxed. After justifying the derivation of the model, the authors provide a rigorous proof of global existence of weak solutions, and well-posedness for strong solutions in dimension three.

实时光谱图像技术的应用是数据和通信的密集型算法的综合。因为片上系统(SoC)具有较大的灵活性及良好的性能,并可以直接采用IP核,基于片上网络(NoC)的SoC架构是实现这种实时系统最合适的解决方案。针对不同的应用算法,调整基于SoC的NoC架构是较为复杂的工作,因为设计空间探索和实验需要大量的时间。针对这些问题,提出了一种探索和评估SoC架构性能的仿真平台。该仿真平台基于NoC和参数化的评估模块,在FPGA上对SoC的通信结构进行仿真,并将时间性能和模拟结果进行对比。基于该仿真平台的系统评估主要用来考察用于油画鉴别应用的MPSoC的性能。

This paper presents the solution of coupled radiative transfer equation with heat conduction equation in complex three-dimensional geometries. Due to very different time scales for both physics, the radiative problem is considered steady-state but solved at each time iteration of the transient conduction problem. The discrete ordinate method along with the decentered streamline-upwind Petrov-Galerkin method is developed. Since specular reflection is considered on borders, a very accurate algorithm has been developed for calculation of partition ratio coefficients of incident solid angles to the several reflected solid angles. The developed algorithms are tested on a paraboloid-shaped geometry used for example on concentrated solar power technologies.

通过分析洛川黄土剖面S1以上地层118个样品的蜗牛化石,划分出6个蜗牛化石组合带。对22个蜗牛化石种类的数据进行分析,选取了6个环境意义明确的主因子。结果表明:约110ka以来,洛川古气候长周期变化具有冷干、暖湿交替演化的总体趋势。但即使在古气候总体趋势呈现干冷的时期,也会阶段性地出现短期的、季节性的湿润环境。文中对影响各类环境因子变化的因素做了初步的讨论。
