简介：自从三座峡水库(TGR)的被坝所围住的水，在TGR的头区域的seismicity显著地增加了。每年结合了水水平的宽变化，学习在TGR旁边山崩预报的变丑变得更重要。作为在TGR旁边的著名活跃山崩，Huangtupo河边山崩为案例研究被选择。基于长期的水水平变化并且地震监视，三个典型不利条件被决定。与确定的3D数字山崩模型，渗出物动态的联合计算在V的地震紧张下面被进行度。结果如下：1。走水路形成的动态水压力水平变化将加强山崩的变丑；2。在地震负担下面，动态磁滞现象在有缺点的地质的身体是重要的，例如弱层并且滑动地区土壤，因为更高抑制比率的大部分，地震加速将在这些元素被放大；3。微震不是足够强烈的突然引起山崩不稳定性，但是山崩的长期的变丑累积效果应该被付更多的注意；4。在数字模拟，因素失衡力量和过量毛孔压力能也在预报山崩的变丑趋势被使用。

简介：AbstractPurpose:Epileptic seizures frequently result in distinct physical injuries, fractures, traumatic brain injuries and minor trauma. The aim of this study was to retrospectively determine the frequent injury patterns due to seizure episode and to analyze consecutive acute medical care.Methods:This retrospective mono-center study was conducted at Frankfurt University Hospital, Frankfurt am Main, Germany between January 2007 and December 2017. Epilepsy patients with seizure-related fractures admitted to the emergency department were identified via a retrospective systematic query in the hospital information system using the ICD-10 German modification codes G40.0—G40.9. Patients with an unclear diagnosis of epilepsy were excluded. Sociodemographic as well as disease specific aspects were analyzed. Descriptive and Kruskal—Wallis one-way analysis of variance were used for statistical analysis.Results:A total number of 62 epilepsy patients were included. The mean age was 58.1 years. Fractures concerned the upper extremity most frequently (43.5%, n= 20), and 70.0% (14/20) were humerus fractures. Admission to intensive care unit for acute trauma care was necessary in 29.0% patients (n = 18), and surgery in 45.2% patients (n = 28). Twenty-five patients (26.6%) showed clinical or radiological signs of traumatic brain injury. Provoking factors were identified in 20 patients (32.3%), i.e., acute withdrawal or excess of alcohol (n = 15), relevant sleep deprivation (n = 2), and intoxication or withdrawal of other illegal drugs or trivial infect (n = 1 for each) and non-compliance with anti-seizure drugs (n = 1). A decreased T-score (-1.04 ± 1.15) and Z-score (-0.84 ± 0.75) compared to healthy subjects were found.Conclusion:Fractures in upper extremities, trunk and craniocerebral trauma occur frequently as seizure-induced injuries. Alcohol excess and withdrawal are important provoking factors and should be targeted with preventive measurements to avoid seizure related injuries and accidents.

简介：一个不连续的Galerkin有限元素方法习惯于古典交通流动PDE的近似答案。这PDE被用来为抄写的生物过程建模；mRNA从DNA把基因信息转移到或到rRNA的过程。抄写过程被短、经常的RNAP标点暂停它作为交通灯被合并到模型。这些暂停在平均抄写过程引起延期。非线性的模型的DG答案被用来计算延期并且在平均抄写时间决定pauses的效果。在DG答案和真答案之间的数字错误大小(由特征的方法发源)为一个简单模型问题被给。它为延期计算在一位邻居显示出一个优秀协议离开震动以及O(x)集中。初步的参数研究在一个系统显示那与多重暂停地点和pauses罐头的时间持续时间显著地影响RNAP经验丰富的平均延期。[从作者抽象]
