简介：扩大电子的一个模型是适合描述经由扫描掘显微镜获得的理论模拟和试验性的结果的更多，这被发现了，但是当动态性质容易被合并时，磁性，并且特别地电子旋转性质当测量不在时由于他们的构思的isotropy提出一个问题。一个电子的旋转与一个磁场反应并且因此有向量的性质。然而，电子纺纱也是各向同性的，建议它没有向量的性质。在对电子旋转的描述的这中央冲突，我们相信，矛盾的性质的许多的根为量旋转粒子被测量并且要求。利用电子旋转在真实三维的空间一致地在被描述的一个模型--一个扩大电子模型--我们证明纺纱可以被向量描述并且仍然维持它的isotropy。在这个框架，我们重新估计连续大小的Stern-Gerlach实验，Einstein-Podolsky-Rosen实验，和效果并且在所有情况中发现相当直觉的解释。

简介：数据包封分析(DEA)和比率分析(RA)是为测量单位生产率和能基于可得到的输入和输出变量被估计的任何另外的标准的二个广泛地使用的方法。很多个研究人员学习了DEA和RA并且注意了他们之间的积极、否定的差别。聚集的比率分析(ARA)模型，提供在DEA和RA理论之间的一个重要连接，等价于CCRDEA模型，并且这个等价性质为以不同方法要解释并且适用的DEA提供很多机会。这份报纸扩大ARA模型的结果并且建议一个扩大聚集的比率分析(EARA)模型，象到在DEA上下文的电子消息传输方式模型的从CCR模型的发展类似。建议模型能提供卓见进回来的特征可伸缩，作为电子消息传输方式模型起相应作用。数字例子在纸被重游，结果被比较。

简介：AbstractBackground:Intravenous thrombolysis (IVT) is an effective way for treating acute ischemic stroke (AIS). However, its effects have not been established among AIS patients with unclear stroke symptoms or with stroke onset for >4.5 h.Methods:We searched PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials and Google Scholar databases for randomized controlled trials that compared IVT (IVT group) and placebo or usual care (control group [CG]) in AIS patients with disease onset for >4.5 h. The outcomes of interest included the favorable functional outcome (defined as modified Rankin Scale [mRS] scores 0-1) at 90 days, the functional independence (defined as mRS scores 0-2) at 90 days, proportion of patients with symptomatic intracerebral hemorrhage (sICH) and death at 90 days. We assessed the risk of bias using the Cochrane tool. Pre-specified subgroup analyses were performed by age (≤70 years or >70 years), National Institute of Health Stroke Scale (NIHSS, ≤10 or >10) and time window (4.5-9.0 h or >9.0 h).Results:Four trials involving 848 patients were eligible. The risk of bias of included trials was low. Patients in the IVT group were more likely to achieve favorable functional outcomes (45.8% vs. 36.7%; OR 1.48, 95% CI 1.12-1.96) and functional independence (63.8% vs. 55.7%; OR 1.43, 95% CI 1.08-1.90) at 90 days, but had higher risk of sICH (3.0% vs. 0.5%; OR 5.28, 95% CI 1.35-20.68) at 90 days than those in the CG. No significant difference in death at 90 days was found between the two groups (7.0% vs. 4.1%; OR 1.80; 95% CI 0.97-3.34).Conclusions:Use of IVT in patients with extended time window may improve their functional outcomes at 90 days, although IVT may induce increased risk of sICH. Care of these patients should well balance the potential benefits and harms of IVT.
