1人体医疗类干预临床试验研究方案信息与结果的国际注册原则——渥太华声明(第Ⅰ部分)显示文摘临床试验的注册在国际临床医学界已经呼吁了多年,其用意在于避免发表偏倚(一种阳性结果临床试验容易获得发表,而阴性的研究结果不容易获得发表的倾向)和选择性报告偏倚。2004年一个由80多名国际临床医学专家、杂志编辑和研究人员共同签署的声明,由6名具有国际知名度的临床试验专家起草、修订和发表了注册临床试验的宣言,即著名的《渥太华声明》。要求任何临床试验的研究方案及随后的试验结果都应当进行注册,并使公众能够获取。该声明已经翻译成英、法、日文;现由国内学者翻译的该声明在本刊发表具有重要意义,将进一步促进临床试验的规范化和质量的提高,并最终接受公众的评价。刘建平 张晶 陈均超 Karmela Krle■a-Jeri An-Wen Chan Kay Dickersin Ida Sim Jeremy Grimshaw Christian Gluud 2006循证医学2006,6,2:5
2High efficiency, high power 808nm laser array and stacked arrays optimized for elevated temperature operation显示文摘Operation of 808-nm laser diode pumping at elevated temperature is crucial to many applications. Reliable operation at high power is limited by high thermal load and low catastrophic optical mirror damage (COMD) threshold at elevated temperature range. We demonstrated high efficiency and high power operation at elevated temperature with high COMD power. These results were achieved through device design optimization such as growth conditions, doping profile, and materials composition of the quantum-well and other layers. Electrical-to-optical efficiency as high as 62% was obtained through lowered threshold current, lowered series resistance and increased slope efficiency. The performance of single broad-area laser diodes scales to that of high power single bars on water-cooled copper micro-channel heatsinks or conductively-cooled CS heatsinks. No reduction in bar performance or significant spectral broadening is seen when these micro-channel coolers are assembled into 6-bar and 18-bar CW stacks for the highest power levels.Crump P A Crum T R DeVito M Farmer J Grimshaw M Huang Z Igl S A Macomber S Thiagarajan P Wise D 2004光机电信息2004,21,6:4
3A short comment on the effect of a shear layer on nonlinear water waves显示文摘In this paper we study nonlinear periodic deep water waves propagating on a background shear current,which decays exponentially with depth.We extend the study of Cheng,Cang and Liao(2009) by introducing a second parameter which measures the depth of the shear current.A high-order convergent analytical series solution is obtained by the homotopy analysis method(HAM).A detailed analysis of the impact of the depth parameter is given.We find that increasing this parameter so that the shear current is thinner reduces the wave phase speed,smoothes the wave crest,sharpens the trough,and enlarges the maximum wave height for the case of propagating waves on an opposing current;while it produces the opposite effect on an aiding current.CANG Jie CHENG Jun GRIMSHAW Roge 2011Science China(Physics,Mechanics & Astronomy)2011,54,1:3
