| 1 | Performance analysis of space-shift keying over negative-exponential and log-normal FSO channels显示文摘The average bit-error rate(ABER) performance of free-space optical(FSO) communication links is investigated for space-shift keying(SSK) over log-normal and negative-exponential atmospheric turbulence channels. SSK is compared with repetition codes and a single-input single-output system using multiple pulse amplitude modulations. Simulation results show that the signal-to-noise ratio gain of SSK largely increases with greater spectral efficiencies and/or higher turbulence effects. A tight bound for ABER is derived based on an exact moment generation function(MGF) for negative-exponential channel and an approximate MGF for log-normal channel.Finally, extensive Monte Carlo simulations are run to validate the analytical analysis. | Mohamed Abaza Raed Mesleh Ali Mansour el-Hadi Aggoune | 2015 | Chinese Optics Letters2015，13，5： | 6 |
| 2 | 回顾性评估中国广州一家大型精神病医院再住院的相关因素(英文)显示文摘背景:中国大多数精神科住院患者是由家人强制性入院,导致住院时间相对较长和再次住院率相对较低。然而,这种模式随着新颁布的中国精神卫生法(颁布于2013年)可能发生变化,该法限定了强制性精神科入院为那些对自己或他人产生危险的小部分精神疾病患者。目标:评估中国广州精神科住院患者再次住院率的相关因素。方法:对从中国最大的精神病医院之一——广州市精神病医院收集来的数据进行回顾性分析,使用Cox回归模型评估年龄、性别、诊断、婚姻状况、就业状况之间的关系,与主要照顾者的关系、医疗保险、指标住院的时间、以往的入院次数之间的关系,进而评估出院后一年内再住院的风险。使用多因素回归分析来评估随访一年中再次住院总时间的相关因素。结果:2011年1月至2012年12月31日间3455例住院患者的平均住院时间(标准差)为65.7(66.3)天,476(13.8%)名患者出院后一年内再入院一次或多次。在将再入院所有可能的预测因素进入多因素生存分析后,指标住院前的以往住院次数是再次住院的唯一有统计学意义的预测因子。与再住院总时间显著相关的唯一因素是指标住院的长短。结论:缩短住院时间并没有增加中国南方一家大型公立精神病院的患者再住院率。这表明,根据中国的新法规,大部分病人自愿入院时不仅不会导致再次住院率的增加,可能还会出现预期的精神病患者的住院时间的缩短。前瞻性研究将需要结合更全面的结果评估(包括患者功能,服药依从性,和家庭负担)来监测精神卫生法对患者和精神卫生服务分布的影响。 | 周燕玲 Rosenheck RA Mohamed S 范妮 宁玉萍 何红波 | 2014 | 上海精神医学2014，26，3： | 5 |
