Event related-potentials (ERPs) are divided into exogenous and endogenous components. The exogenous components include P1, N1 and P2 waves, and the endogenous include N2 and P3 waves. The endogenous components are sensitive to psychological variables. There were a few of reports about ERPs of Characters of Chinese Words (CWW). We studied the ERPs and reaction time (RT) elicited by stimulation with CCW on adolescents and aged persons, and compared them with ERPs to tone and picture stimuli.

Fischer-Tropsch synthesis （FTS） is an increasingly important approach for producing liquid fuels and chemicals via syngas-that is, synthesis gas, a mixture of carbon monoxide and hydrogen-generated from coal, natural gas, or biomass. In FTS, dispersed transition metal nanoparticles are used to catalyze the reactions underlying the formation of carbon-carbon bonds. Catalytic activity and selectivity are strongly correlated with the electronic and geometric structure of the nanoparticles, which depend on the particle size, morphology, and crystallographic phase of the nanoparticles. In this article, we review recent works dealing with the aspects of bulk and surface sensitivity of the FTS reaction. Understanding the different catalytic behavior in more detail as a function of these parameters may guide the design of more active, selective, and stable FTS catalysts.

AIM： To investigate the role of IFN-T inducible protein -10 （IP-10） and regulated upon activation, normal T cell expressed and secreted （RANTES） protein in acute pancreatic allograft rejection in rats. METHODS： An experimental model was established using pancreas transplantation diabetic SD rats as the recipient, induced by applying streptozocin （STZ）. Pancreas transplantation was performed with a physiologic method of portal venous and enteric drainage. Rats were divided into two groups, isograft group （group A, n = 24） and allograft group （group B, n = 24） in which either healthy SD rats or Wistar rats served as donors, respectively. Twelve diabetic or healthy SD rats were used as controls. At d 1, 4, 7, and 10 post transplantation, serum IP-10 and RANTES were assessed by ELISA and their expression in the allografts was determined by immunohistochemistry. RESULTS： In group B （allograft group）, the development of acute rejection was significantly correlated with increased serum concentration and tissue expression of IP-10 and RANTES, with a peak level at d 7 post transplantation. In contrast, there was no obvious change before and after transplantation in group A （isograft group）. CONCLUSION： Our study suggests a possible role of IP-10 and RANTES in acute rejection and early monitoring of chemokines may be helpful in predicting the outcome of pancreas transplantation.

On the Tectonic Evolution of the Kunlun-Karakorum Area, Southern Xinjiang, Northwest China

第26届中国控制与决策会议

By combining two fast training methods, i.e., the weights-direct-determination（WDD） method and Levenberg-Marquardt method, this paper proposes a novel training algorithm called weights and structure policy（WASP）for the three-layer feedforward neuronet, in addition to the algorithm of weights and structure determination（WASD）.Note that the pruning-while-growing and second-pruning techniques are developed and exploited in the WASP algorithm with the aim of achieving a neuronet with a simple and economical structure. In order to verify the WASP efficacy and to address the problem of chronic kidney disease（CKD） for clinical applications in China, numerical experiments about estimating glomerular filtration rate（GFR） by the WASP neuronet and traditional GFR-estimation equations are conducted and compared. The experiment results show that the WASP training speed is fast and that the estimating accuracy via the WASP neuronet is around 20% higher than those via traditional GFR-estimation equations. The WASP efficacy is thus demonstrated with a significant value in GFR estimation of CKD for clinical applications.

Continental Dynamics 1999年第2期 65-72页

作者： liu xun and FU Derong (Institute of Geology, CAGS Beijing 100037)

The part of the Kunlun-Karakorum cut across by the Xinjiang Geotransect can be divided into four terranes. Among them are three main boundary faults. In this papen through the simple introduction about the principal characteristics of the terranes and their boundary faults, we discussed the tectonic evolution of this area. Particularly, we emphasise that the Kangxiwar Fault is a suture zone, which represented the Paleo-Tethys oceanic basin separating the Qiangtang plate from the Tarim plate. After its closure in the end of Triassic, the Kunlun-Karakorum area amalgamated into a unified continent and began their intracontinental orogenic stage.
