We present theoretical and experimental studies of Schottky diodes that use aligned arrays of single-walled carbon nanotubes. A simple physical model, taking into account the basic physics of current rectification, can adequately describe the single-tube and array devices. We show that for as-grown array diodes, the rectification ratio, defined by the maximum-to-minimum-current-ratio, is low due to the presence of metallic-single-walled nanotube (SWNT) shunts. These tubes can be eliminated in a single voltage sweep resulting in a high rectification array device. Further analysis also shows that the channel resistance, and not the intrinsic nanotube diode properties, limits the rectification in devices with channel length up to 10 μm.

Hyperlipidemia is a well-established risk factor for developing cardiovascular disease(CVD). The recent American College of Cardiology and American Heart Association guidelines on lipid management emphasize treatment of individuals at increased risk for developing CVD events with 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors(statins) at doses proven to reduce CVD events. However, there are limited options for patients who are either intolerant to statin therapy, develop CVD despite being on maximally tolerated statin therapy, or have severe hypercholesterolemia. Recently the Food and Drug Administration approved two novel medications for low-density lipoprotein(LDL)-cholesterol reduction: Evolocumab and Alirocumab. These agents target and inactivate proprotein convertase subtilsinkexin type 9(PCSK9), a hepatic protease that attaches and internalizes LDL receptors into lysosomes hence promoting their destruction. By preventing LDL receptor destruction, LDL-C levels can be lowered 50%-60% above that achieved by statin therapy alone. This review explores PCSK-9 biology and the mechanisms available to alter it; clinical trials targeting PCSK9 activity, and the current state of clinically available inhibitors of PCSK9.

用“双套管法”淬火测定Cu:Cu-Al扩散偶中的相平衡,由于该法具有较快的冷却速度,保证了α/β相界面处于局部平衡.传统的淬火方法冷速通常是不够快的,不足以抑制β相的分解.较慢的冷却使界面形貌发生改变;测出的界面浓度是较低温度下的数值.有理由相信,Eifert等实验得到的各温度下都远较平衡浓度为高的α/β相界浓度,是由于实验过程中较慢的冷速所导致.

Case Reports in Clinical Medicine 2023年第7期12卷 213-217页

作者： Samer Alkhuja Monika Girgis Mohammad Ali Pravinkumar Patel Olutunde Odeyemi Department of Medicine The Commonwealth Medical College Lehigh Valley Health Network-Pocon Stroudsburg Pennsylvania USA

Background: Varenicline, which is derived from the cytisine compound, is used to assess in smoking cessation. Sleep driving (SD) is often classified as a variant of somnambulism. Although, somnambulism has been reported as a side effect of varenicline, varenicline-induced sleep driving (VISD) has not been reported. Case Report: A 56-year-old man with a history of 35 pack year smoking who presented for smoking cessation counseling. Treatment with varenicline was initiated. In the following night, the patient drove to a shopping center and woke up in his car. Varenicline was discontinued. SD has not been reported in the following nights. In a repeated attempt to stop smoking, treatment with varenicline was resumed by the patient. SD reoccurred in the following night. Varenicline was discontinued indefinitely, and SD has not been reported.

The island of Jamaica is often cited as an example of how overfishing has dramatically reduced the sizes of coral reef fishes. To examine the change in fish sizes over a 36-year period, we analyzed data from systematic surveys conducted in 1977 and 2013/14 of the sizes and relative abundances of four common algae-grazing fishes in the shallow backreef habitats of Jamaica and Grand Cayman. The four species are: striped parrotfish (Scarus iseri), stoplight parrotfish (Sparisoma viride), ocean surgeon (Acanthurus tractus) and the blue tang (Acanthurus coeruleus). We predicted that all four species would be larger in Grand Cayman than in Jamaica in 1977 as well as in 2013/14, because Grand Cayman has been cited as having less fishing pressure than Jamaica. For the same reason, we expected all four species would have declined in size over the 36 years in Jamaica but not in Grand Cayman. Furthermore, we predicted that the compressed body shape of the ocean surgeon and the blue tang would have made them especially vulnerable to net and trap fishing compared to the two parrotfishes, and that accordingly the effects of overfishing would be greater in these two species. We rejected this hypothesis. The size distributions of the laterally compressed species changed significantly on both islands over the 36-year time span, although not as predicted. At both islands, the blue tangs shifted toward smaller sizes and the ocean surgeons shifted toward larger sizes. There were no size distribution changes detected in the two fusiform species. There was also no support for the prediction that the sizes of these four species were larger in Grand Cayman than in Jamaica during either time period.

对无硼、含硼５００ｗｐｐｍ和含硼２０００ｗｐｐｍ的多晶Ｎｉ_３Ａｌ在７００～１０００℃范围内的再结晶和晶粒长大过程进行了研究。其中无硼和部分含硼５００ｗｐｐｍ的合金曾经受了１７％的冷压加工，而部分含硼５００ｗｐｐｍ和含硼２０００ｗｐｐｍ的合金分别经受了２０％和４０％的冷轧加工。研究中没有观察到明显可见的硼对再结晶和晶粒长大动力学的影响。上述材料的再结晶过程都遵循ＫＪＭＡ关系，并且都具有接近于１的Ａｖｒａｍｉ指数。晶粒长大过程都遵循指数关系，其时间常数均小于０．５。晶界类型分布（ＧＢＣＤ）测定结果表明，硼的加入强烈影响孪晶界（∑３晶界）出现的频度，把这一因素挪去，便看不到硼对任意晶界及其它类型晶界的作用。再结晶激活能与变形量之间的关系由实验结果揭示并定量导出。本文还就冷加工储能以及位错密度对再结晶的影响进行了讨论。
