High Order Compact Schemes in Projection Methods for Incompressible Viscous Flows

Communications in Computational Physics 2011年第4期9卷 994-1019页

作者： Michel fournie Alain Rigal Institut de Mathematiques de Toulouse Universite de Toulouse et CNRS(UMR 5219)France

Within the projection schemes for the incompressible Navier-Stokes equations(namely"pressure-correction"method),we consider the simplest method(of order one in time)which takes into account the pressure in both steps of the splitting *** this scheme,we construct,analyze and implement a new high order compact spatial approximation on nonstaggered *** approach yields a fourth order accuracy in space with an optimal treatment of the boundary conditions(without error on the velocity)which could be extended to more general *** prove the unconditional stability of the associated Cauchy problem via von Neumann *** we carry out a normal mode analysis so as to obtain more precise results about the behavior of the numerical *** we present detailed numerical tests for the Stokes and the Navier-Stokes equations(including the driven cavity benchmark)to illustrate the theoretical results.

Investigation of the efficiency of intrastromal ring segments with cross-linking using different sequence and timing for keratoconus

· AIM: To evaluate and compare the efficacy and stability of intrastromal corneal ring segment(ICRs)implantation with cross-linking(CXL) using different sequence and timing.· METHODS: In this single retrospective study, 86 keratoconic eyes subjected the ICRs implantation. We analyzed only 41 eyes that had complete *** were divided into three groups: ICRs implantation was applied only(group normal), ICRs first followed by CXL immediately(group CXL-S), CXL first followed by ICRs long after(group CXL-B). The visual acuity,refractive results, keratometry were compared preoperatively and 1y postoperatively. Their differences among the three groups were also analyzed.·RESULTS: Group normal comprised 25 eyes, group CXL-S 8 eyes, and group CXL-B 8 eyes. There were improvements in the mean uncorrected distance visual acuity(UDVA) and the mean corrected distance visual acuity(CDVA) compared preoperatively and 1y postoperatively [UDVA: 0.31(P =0.030) logarithmic minimum angle of resolution(log MAR) group normal, 0.4(P =0.020) group CXL-S, 0.45(P =0.001) group CXL-B;CDVA : 0. 21 log MAR( P = 0. 013) group normal, 0. 30(P =0.036) group CXL-S; 0.26(P =0.000) group CXL-B].The refractive and topographic outcomes also showed improvements. In terms of comparisons among the three groups, all the P values were above 0.05, showing no significant difference. But only group CXL-B had improvement in UDVA and CDVA for all the patients.·CONCLUSION: With safety and good visual outcomes,ICRs implantation is a viable alternative for *** significant difference was found among these three groups.

What lessons can be learned from y T cell-based cancer immunotherapy trials？

Cellular & Molecular Immunology 2013年第1期10卷 35-41页

During the last several years, research has produced a significant amount of knowledge concerning the characteristics of human 76 T lymphocytes. Findings regarding the immune functions of these cells, particularly their natural killer cell-like lyric activity against tumor cells, have raised expectations for the therapeutic applications of these cells for cancer. Pharmaceutical companies have produced selective agonists for these lymphocytes, and several teams have launched clinical trials of y8 T cell-based cancer therapies. The findings from these studies include hematological malignancies （follicular lymphoma, multiple myeloma, acute and chronic myeloid leukemia）, as well as solid tumors （renal cell, breast and prostate carcinomas）, consisting of samples from more than 250 patients from Europe, Japan and the United States. The results of these pioneering studies are now available, and this short review summarizes the lessons learned and the role of y6 T cell-based strategies in the current landscape of cancer immunotherapies.

在1970到1977年期间,由于耐用性试验的使用,评定纸-聚丙烯组合绝缘性能已经成为可能。已开展两个试验: ──在热和电应力下的加速老化试验使得绝缘不受缩短其寿命的物理-化学反应的影响得以确定。──包括施加热应力的过电压耐受试验用来检验在低温下投入时不致引起绝缘的恶化,而如果发生局部放电,均以结构上的安排来适当地抵消。综观所得到的结果表明,这里介绍的试验能增进我们对由纸-聚丙烯组合介质构成的绝缘系统恶化过程的认识。耐用性试验,过电压,纸-聚丙烯,电力电容器,热老化。
