1Highly efficient GaAs solar cells by limiting light emission angle显示文摘In a conventional flat plate solar cell under direct sunlight,light is received from the solar disk,but is re-emitted isotropically.This isotropic emission corresponds to a significant entropy increase in the solar cell,with a corresponding drop in efficiency.Here,using a detailed balance model,we show that limiting the emission angle of a high-quality GaAs solar cell is a feasible route to achieving power conversion efficiencies above 38%with a single junction.The highest efficiencies are predicted for a thin,light trapping cell with an ideal back reflector,though the scheme is robust to a non-ideal back reflector.Comparison with a conventional planar cell geometry illustrates that limiting emission angle in a light trapping geometry not only allows for much thinner cells,but also for significantly higher overall efficiencies with an excellent rear reflector.Finally,we present ray-tracing and detailed balance analysis of two angular coupler designs,show that significant efficiency improvements are possible with these couplers,and demonstrate initial fabrication of one coupler design.Emily D Kosten Jackson H Atwater James Parsons Albert Polman Harry A Atwater 2013Light(Science & Applications)2013,2,1:9

3Terahertz pulse imaging in archaeology显示文摘在这份报纸介绍的工作在芝加哥大学在东方研究所被执行,在从他们的永久收集的目标上:一具古老的埃及鸟木乃伊和三个古老的闪族语的侵蚀的铜合金目标。我们使用了便携式的、联合纤维的兆兆赫(THz ) 时间域分光镜的成像系统,它允许我们在传播和思考几何学测量标本,和基于时间、基于频率的现在想象模式。结果证实 THz 成像能提供互补信息给那的更早的证据从计算断层摄影术(XRCT ) 木乃伊扫描的 X 光检查可获得,给低密度区域的更好的可视化。另外,我们证明 THz 成像能在金属人工制品区分使矿物化的层。J.

4多重结局的多元Meta分析和多重治疗的网状Meta分析:原理、概念及实例显示文摘英国国家健康与临床优选研究所(NICE)等组织需要对现有研究获得的证据进行整合来指导决策,需要确定关于多重疗效及安全性结局的最佳治疗。但是,相关的研究不一定对所有关注的治疗或结局都进行了直接比较,多元Meta分析及网状Meta分析为如何确定最佳治疗这一问题提供了思路,该方法不仅考虑了直接证据,还利用了关联或间接的证据。本文中,研究者描述了这些方法学的重要概念及假设,并阐述关联及间接证据如何产生,同时通过图表说明这些证据在涉及多重结局和多重治疗的真实临床案例中如何使用。Richard D Riley Dan Jackson Georgia Salanti Danielle L Burke Malcolm Price Jamie Kirkham Ian R White 孙至佳(译) 张岩(译) 刘雪晴(译) 杨智荣(校) 孙凤(校) 2018英国医学杂志中文版2018,21,12:2

11脊髓损伤后残存自主神经功能载录国际标准显示文摘近年来,脊髓损伤神经学分类园际标准(International Stand- ards for the Neurological Classification of Spinal Cord Injury, ISNCSCI)被用来记载脊髓损伤后运动和感觉功能的损害,目前该标准已是第六版。1992年第一份国际认可的标准出版时,曾进行了较大的修订,修订内容包括完全性损伤与不完全性损伤的定义,MS Alexander AB Jackson W Donovan DE Graves SL Elliott A Krassioukov AW Sheel I Estoresl B Green A Gousse NL Braekett D Cardenas M Kennelly A-K Karlason F Biering-Sorensen K Krogh T Linsenmeyer R Marino J Ditunno CJ Mathias I Perkash G Creasey G Schilero J Wecht B Schurch V Dietz J Sonksen S Stiens D Bodner LA Wuermser J-J Wyndaele 周谋望 刘楠 S Charlifue 2010中华物理医学与康复杂志2010,32,4:2
12相对运动强度与绝对运动强度对血清酶活性的影响显示文摘目的探讨相对运动强度和绝对运动强度对血清酶活性变化的影响。实验方法受试者为急性心肌梗塞康复病人(PMIP)和正常人(HS) ,实验前后测定了他们血清乳酸脱氢酶(L DH)、乳酸脱氢酶同工酶1(L DH- 1)、肌酸激酶(CK)、肌酸激酶亚单位MB(CK- MB)活性。结果两组受试者运动前酶的活性均无显著差异(P>0 .0 5 ) ;实验中,PMIP与HS的相对强度分别为最大心率的85 .1%、86 .0 % (P>0 .0 5 ) ,绝对强度分别为跑台等级的5 .3与6 .3(P<0 .0 5 ) ,PMIP与HS运动后即刻酶活性与运动前相比均有显著上升(P<0 .0 5 ) ,但两组间无显著差异(P>0 .0 5 ) ,2 4 h后HS组的酶活性基本恢复到运动前水平,但PMIP组仍高于运动前水平。结论运动后酶活性上升的幅度与运动所达到的相对强度有关;强度达85 % HRmax的运动能引起血清酶活性的升高,但此时L DH- 1/L DH和CK- MB/CK的比值与运动前相比无明显变化;如果PMIP的康复运动量等同于测试中的运动量,他们第2天似应停止活动以便能够得到充分的恢复。刘洵 谭思洁 Brodie D A Jackson M Bundred P E 2005体育科学2005,25,5:2
