We report a study of the roles of gadolinium(lll)(Gd3+)dopants in influencing the catalytic activity of gadolinium-doped ceria nanoparticles towards the pro-oxidation of hydrogen peroxide to hydroxyl *** doped ceria nanoparticles with dopant concentrations of 0.6 wt.%,3 wt.%,and 6 wt.%Gd^3+were synthesized using an ozone-mediated method for tuning their catalytic *** Gd dopants were found to foster an increase in the percentage of Ce^3+ions in the doped ceria *** reaction kinetic study revealed that the relationship between the overall reaction rates and the Gd dopant concentrations in our doped materials followed a volcano-like *** contrast,the apparent activation energy values of these Gd-doped ceria nanoparticles were found to be positively associated with the concentrations of Gd *** overall catalytic activity trend was attributed to the interplay between the promotion and degradation effects of the Gd dopants on the properties of doped ceria nanoparticles.

作者： GRANBERG carl j. Department of Computing Curtin University of Technology Perth Australia

In this paper we present a novel method for dividing and clustering large volumetric scalar out-of-core datasets. This work is based on the Ordered Cluster Binary Tree (OCBT) structure created using a top-down or divisive clustering method. The OCBT structure allows fast and efficient sub volume queries to be made in combination with level of detail (LOD) queries of the tree. The initial partitioning of the large out-of-core dataset is done by using non-axis aligned planes calculated using Principal Component Analysis (PCA). A hybrid OCBT structure is also proposed where an in-core cluster binary tree is combined with a large out-of-core file.

＜正＞We have developed a novel technology which can be used to prepare highly uniform polymeric microparticles with controlled pore structure and high rigidity. The monodispersed polymeric micorparticles have demonstrated superior performances in column chromatography separation and analysis of biomacromolecules. For example, influenza peptide M1, [H]-Gly-Ile-Leu-Gly-Phe-Val-Phe-Thr-Leu-[OH], is of interest for its utility in the area of vaccine

作者： carl L. Gardner Steven j. Dwyer School of Mathematical and Statistical Sciences Arizona State University Tempe AZ 85287 USA

Computational gas dynamical simulations using the WENO-LF method are applied to modeling the high Mach number astrophysical jet XZ Tauri, including the effects of radiative cooling. Mach 55 simulations of the pulsed proto-jet are presented and analyzed in terms of interacting nonlinear waves： terminal Mach disks, bow shocks, and Meshkov-Richtmyer instabilities of the leading jet contact boundary.

由于数字声频系统的潜在的透明性和最终信号的高质量,对听众进行高质量信号的数字广播是具有吸引力的。用传统的脉码调制(PCM)法进行信号处理尽管性能良好,但在接收机中需要采用复杂而精确的电路,因此价格昂贵。Dolby实验室已研究出一种自适应增量调制(ADM)法,采用这种方法,在接收机中使用简单得多的、廉价的译码器就可获得与PCM相当的质量。
