AIM: to evaluate the light adjustable lens(lAl) vs a standard monofocal lens in achieving target astigmatic refraction and improving postoperative uncorrected distance visual acuity(UDVA). MEtHODS: this randomized controlled clinical trial included 40 patients with pre-existing astigmatism and visually significant cataract. twenty-eight patients received the lAl and 12 control patients received a monofocal intraocular lens(IOl) after cataract extraction at a single institution. the patients with the lAl underwent adjustment by ultraviolet(UV) light postoperatively plus subsequent lock-in procedures and all patients returned to clinic for follow up of study parameters at 6, 9, and 12 mo. Manifest refraction, distance visual acuity, and adverse events were recorded at each ***: the mean cylinder before adjustment in eyes with the lAl was-0.89±0.58 D(-2.00 to 0.00 D) and-0.34±0.34 D(-1.25 to 0.00 D) after lock-in(P=1.68 x10-8). the mean cylinder in patients with the monofocal lens was-1.00±0.32 D(-1.50 to-0.50 D) at 17-21 d postoperatively, which was statistically different from the lAl cylinder postlock-in(P=1.43 x10-6). UDVA in the lAl group was 20/20 or better in 79% of patients post lock-in with good stability over 12 mo compared with 33% of the control patients with UDVA of 20/20 or better. CONClUSION: these results demonstrate that the lAl is more effective in achieving target refractions and improving postoperative UDVA in patients with pre-existing corneal astigmatism than a standard monofocal lens.

地球大气中CO_2浓度的增加已引起了人们对CO_2对植物的影响,尤其是对世界粮食供应的未来展望的兴趣。水稻是一种主要的粮食作物,人们对CO_2浓度在水稻生理生长期和整个生育期方面的影响了解相对较少,而这是一个水稻品种对一特定地区环境适应性的一个重要方面。本研究的目的是确定一个当代改良水稻品种(Oryza sativa,品种 IR-30)在两个对照的光周期下对不同CO_2浓度的响应。在整个生育期中,水稻植株生长在置于室外、采用自然光照并由计算机控制环境条件的人工气候室中。室内的CO_2浓度分别为160、250(低于环境浓度)、330(环境浓度)、500、660和900(高于环境浓度)μmol CO_2/mol 空气。在1987年,整个试验进行了两次。第一次即早稻试验在营养生长阶段内延长了光周期,而第二次即晚稻(lPR)试验只利用自然出现的光周期。在两个试验中,营养生长期的主茎叶片发育速率均比生殖生长期的主茎叶片发育速率快,同时在营养生长阶段,出叶速度随CO_2处理而加快。在晚稻试验中,与等于环境CO_2浓度和低于环境CO_2浓度的处理相比,高于环境CO_2浓度处理下的水稻幼穗分化和孕穗期出现较早,且整个生育期缩短。这种随CO_2浓度上升而产生的植物发育加速现象与CO_2引起的营养生长阶段内主茎叶片的减少有关。相对于晚稻试验,在早稻试验中水稻植株发育对CO_2的响应的减弱是由人为延长光周期迫使生殖生长发育阶段推迟引起的,在高于环境浓度处理中更是如此。鉴于全球大气中CO_2浓度的持续增大,CO_2导致的发育加速和全生育期缩短可能会成为一个参与挑选水稻品种和安排特定地区农事活动的水稻学家和育种学家感兴趣的问题。

twelve weeks of dance exergaming in overweight and obese adolescent girls:transfer effects on physical activity,screen time,and self-efficacy

Journal of Sport and Health Science 2017年第1期6卷 4-10,127页

作者： Amanda E.Staiano Robbie A.Beyl Daniel S.Hsia Peter t.Katzmarzyk robe.t l.Newton jr Pennington Biomedical Research Center Baton RougeLA 70808USA

Background: Given the low levels of physical activity(PA) among adolescent girls in the US, there is a need to identify tools to motivate increased PA. Although there is limited evidence that adolescents transfer PA from one context to another, exergames(i.e., video games that require gross motor activity) may act as a gateway to promote overall PA outside game play. the purpose of this study was to examine potential transfer effects(i.e., influences on external behaviors and psychological constructs) of a 12-week exergaming intervention on adolescent girls' PA, screen time,and self-efficacy toward PA, as well as the intrinsic motivation of ***: Participants were 37 girls aged 14–18 years(65% African American, 35% white) who were overweight or obese(body mass index ≥ 85 th percentile) and were recruited from the community via school, physicians, news media, and social media websites. Adolescents were randomly assigned to a 12-week group exergaming intervention(thirty-six 60 min sessions of group-based dance exergaming in a research laboratory using Kinect for Xbox360(Microsoft Corporation, Redmond, WA, USA)) or to a no-treatment control group. Outcome variables included objectively measured PA(total) and self-reported leisure-time PA(discretionary time only) 1 week before vs. 1 week after the intervention; selected type and intensity of PA when placed in a gym setting for 30 min("cardio free choice"); screen time; self-efficacy toward PA; and intrinsic motivation toward ***: Attendance at the exergaming sessions was high(80%). Compared with the control group, the intervention group self-reported an increase in PA(p = 0.035) and fewer hours watching television or videos(p = 0.01) after the intervention, but there were no significant differences in sedentary, light, moderate, or vigorous PA measured by accelerometry. the intervention group significantly improved self-efficacy toward PA(p = 0.028). the intervention group highly rated intri

Real-time Mesoscale Forecast Support During the ClAMS Field Campaign

Advances in Atmospheric Sciences 2007年第4期24卷 599-605页

作者：王东海 P. MINNIS t. P. CHARlOCK D. K. ZHOU F. G. ROSE W. l. SMItH W. l. SMItH jr.l.

Hampton Virginia

this paper reports the use of a specialized, mesoscale, numerical weather prediction （NWP） system and a satellite imaging and prediction system that were set up to support the ClAMS （Chesapeake lighthouse and Aircraft Measurements for Satellites） field campaign during the summer of 2001. the primary objective of ClAMS was to validate satellite-based retrievals of aerosol properties and vertical profiles of the radiative flux, temperature and water vapor. Six research aircraft were deployed to make detailed coincident measurements of the atmosphere and ocean surface with the research satellites that orbited overhead. the mesoscale weather modeling system runs in real-time to provide high spatial and temporal resolution for forecasts that are delivered via the World Wide Web along with a variety of satellite imagery and satellite location predictions. this system is a multi-purpose modeling system capable of both data analysis/assimilation and multi-scale NWP ranging from cloud-scale to larger than regional scale. this is a three-dimensional, non-hydrostatic compressible model in a terrain-following coordinate. the model employs advanced numerical techniques and contains detailed interactive physical processes. the utility of the forecasting system is illustrated throughout the discussion on the impact of the surface-wind forecast on BRDF （Bidirectional Reflectance Distribution Function） and the description of the cloud/moisture forecast versus the aircraft measurement.

the present paper studied numerical and experimentally the transesterification reaction between sunflower oil and ethanol with NaO H catalyst in microchannels with circular obstructions. the micromixer design influence on fluid mixing and oil conversion was investigated for a range of operating conditions: Reynolds number(Re = 0.1–100),temperature(25–75 °C), ethanol/oil molar ratio(6-12), and catalyst concentration(0.75 wt%–1.25 wt%), using three microchannel configurations(length = 35 mm; Width = 1500 μm; Height = 200 μm): t-shape – channel without obstructions; MCO – channel with 3 obstructions ensemble – equally disposed over longitudinal length;MWO – channel with 7 obstructions ensemble. the MCO micromixer was based on literature work, and the MWO is a totally new micromixer design. Experimental tests were conducted in similar conditions in microreactors using these micromixers(length = 411 mm) made of polydimethylsiloxane. the MCO configuration presented the highest performance(mixing index of 0.80 at Re = 100), oil conversion of 81.13% at 75 °C, molar ratio of 9 and catalyst concentration of 1%. Experimental results showed high conversions for MCO and MWO configurations(99.99%) at 50 °C, molar ratio of 9 and catalyst concentration of 1%, with a residence time of 12 s.

在本教程综述中,我们重新阐述和表达了镧系离子间无辐射能量传递(Et)速率的理论形式,并且强调了考虑镧系离子本身特异性所引发的与Förster和Dexter理论不同之处。所给出的表达式遵循了Judd-Ofelt的4f-4f跃迁理论框架之下的Kushida方法,并计入了如下电多极机制:偶极-偶极(W_(d-d))、偶极-四极(W_(d-q))和四极-四极(W_(q-q))。更为重要的是,当前的机制也扩展包括了交换(W_(ex))和磁偶极子-磁偶极子(W_(md-md))作用,并经过改进进一步包含了屏蔽效应以及给出了F因子(费米黄金规则中的态密度)的解析表达式。与Kushida的原始方法类似,我们只考虑了强制电偶极子(FED)对Judd-Ofelt强度参数的贡献,并细节性地讨论了磁偶极-磁偶极相互作用的选择定则以及相关矩阵元的计算。此外,我们还以tb(Ⅲ)-Eu(Ⅲ)和Yb(Ⅲ)-Er(Ⅲ)的能量传递速率计算为例,逐步展示了计算过程、主要的计算支撑信息以及所使用的计算脚本。
