目的：确定伴有高调节性辐辏与调节比率（AC／A）的部分调节性内斜视患者，根据配戴全部矫正远视眼镜时1／3m的内斜角接受手术后15年的效果。方法：回顾性图表复习以确定25例患者15年的效果，其6个月的效果以前作为一项前瞻性随机化不知病情的临床验证的一部分已经报告过。所有患者有部分调节性内斜视伴高AC／A比率，并接受了根据配戴全部看远的光学矫正时1／3m的内斜视的手术。结果：术后15年，在随访资料可用的22例患者中，19例内斜度为0至＜10三棱镜度（PD），这19例中只有6例需要继续配戴光学矫正以维持满意的眼位，然而，还有8例因视力的目的需要眼镜。只有1例患者需要使用附加双焦点镜获得在1／3m满意的眼位。所有患者显示有一定程度的感觉性融合，4例获得40s的立体视，另8例获得60－200s的立体视。结论：对配戴全部矫正远视眼镜患者的近距离斜视角手术，在部分调节性内斜视伴有高AC／A比率的患者中提供了的运动和感觉效果。

Introduction Patients with stroke-like symptoms may be underutilising emergency medical services and avoiding hospitalisation during the COVID-19 *** investigated a decline in admissions for stroke and transient ischaemic attack(TIA)and emergency department(ED)stroke alert *** We retrospectively compiled total weekly hospital admissions for stroke and TIA between 31 December 2018 and 21 April 2019 versus 30 December 2019 and 19 April 2020 at five US tertiary academic comprehensive stroke centres in cities with early COVID-19 outbreaks in Boston,New York City,Providence and *** collected available data on ED stroke alerts,stroke severity using the National Institutes of Health Stroke Scale(NIHSS)and time from symptom onset to hospital *** Compared with 31 December 2018 to 21 April 2019,a decline in stroke/TIA admissions and ED stroke alerts occurred during 30 December 2019 to 19 April 2020(p trend<0.001 for each).The declines coincided with state stay-at home recommendations in late *** greatest decline in hospital admissions was observed between 23 March and 19 April 2020,with a 31%decline compared with the corresponding weeks in *** of the five centres with 2019 and 2020 stroke alert data had a 46%decline in ED stroke alerts in late March and April 2020,compared with *** baseline NIHSS during these 4 weeks was 10 in 2020 and 7 in *** was no difference in time from symptom onset to hospital *** At these five large academic US hospitals,admissions for stroke and TIA declined during the COVID-19 *** was a trend for fewer ED stroke alerts at three of the five centres with available 2019 and 2020 *** stroke therapies are time-sensitive,so decreased healthcare access or utilisation may lead to more disabling or fatal strokes,or more severe non-neurological complications related to *** findings underscore the indirect effects of this *** health offici

Computer simulation continues to become more important as a system design tool as computers become more powerful and less expensive. The use of computers allows designers to produce simulations that are much more complex than traditional "linearized" mathematical models, which are generally valid only for small perturbations around an operating point. However, a more complex model requires a more complex system of equations to describe the model. This in turn requires a much more detailed knowledge of the system behavior including details of internal operation that may be very difficult to measure and quantify. One way to overcome some of the difficulties with creating complex computer models is the use of system identification to create an approximation of system behavior by analyzing input-output relationships in experimental data. Neural networks can be used as a basis for system identification. Neural networks theoretically have the ability to model very complex behavior and there is a well defined set of methods for matching neural network model behavior to input-output *** overall objective of this research was to worktowards a neural network model of a hydraulic load-sensing pump that can be used with other component models in a hydraulic system simulation. In this study, neural networks were used to model a load-sensing pump and control valve using experimental data. A combined model of the pump and control valve was created and methods were investigated for expanding the valid operating range of the model by increasing the "richness" of the experimental data. The models was tested with a wide variety of system inputs and the results were compared with experimental data. Analysis showed that an increase in the operating range of the experimental system can cause problems with the repeatability of the measurement transducers which leads to difficulty in training the neural network models, and inaccuracy during *** was established, through this wor

Scheiman等采用适当的科学和方法学来研究集中功能不全（CI）的治疗。尽管CI很常见，有报道其发病率为2．3％～8．3％，但仍然缺少关于目前几种流行的治疗方案的比较研究。Scheiman和他同事的示范研究确实使我们对于治疗这一疾病的认识向前发展。他们将在医院进行的强化治疗（相对费用高）同家庭的小强度治疗以及安慰性治疗相比较，显然在这示范研究中课题的数量是少的。作者发现医院治疗很有效，而家庭治疗以及安慰性治疗则没有效果。

文献报道了MES的许多优点,也提到其性质上可能存在的某些缺点。比如,研究表明纯组分MES的浊点高于其他阴离子表面活性剂,于是怀疑MES的溶解性可能会限制其在冷水中的洗涤。再则,MES的水解稳定性低于其他阴离子表面活性剂,这可能是MES的另一个主要缺点。拟探讨这些问题,并将提出一些证据,以表明MES实际上是一种卓越的表面活性剂,完全可以配方出适用于低温洗涤的洗涤剂产品。介绍了一些采用MES为主要表面活性剂生产洗衣粉和液洗剂的工艺。
