简介:改进集中的能力预先叠时间移植允许想象的节反映结构的特征,深度,和接口形状,它是为起始的深度迁居速度模型的准备的关键步。传统的对称的旅行时间方程基于一个分层的模型的假设被导出。完成与强壮的侧面的变化集中在媒介的需要的效果是困难的。非对称的旅行时间方程基于谎言代数学和一个伪differential操作符包含能甚至在强烈侧面的可变媒介并且也改进集中的能力的侧面的速度衍生物为相对振幅保藏的重量系数的计算精确。与对称的方法相比,非对称的方法是更有效的。在这篇论文,我们描述几关键步非对称预先叠旅行时间计算和现在的一些测试用合成、真实的数据结果。

简介:AbstractWith the coronavirus disease 2019 (COVID-19) pandemic showing no signs of abating, resuming neglected tropical disease (NTD) activities, particularly mass drug administration (MDA), is vital. Failure to resume activities will not only enhance the risk of NTD transmission, but will fail to leverage behaviour change messaging on the importance of hand and face washing and improved sanitation—a common strategy for several NTDs that also reduces the risk of COVID-19 spread. This so-called "hybrid approach" will demonstrate best practices for mitigating the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by incorporating physical distancing, use of masks, and frequent hand-washing in the delivery of medicines to endemic communities and support action against the transmission of the virus through water, sanitation and hygiene interventions promoted by NTD programmes. Unless MDA and morbidity management activities resume, achievement of NTD targets as projected in the WHO/NTD Roadmap (2021-2030) will be deferred, the aspirational goal of NTD programmes to enhance universal health coverage jeopardised and the call to 'leave no one behind’a hollow one. We outline what implementing this hybrid approach, which aims to strengthen health systems, and facilitate integration and cross-sector collaboration, can achieve based on work undertaken in several African countries.

简介:以便改进3D的效率近表面的速度模型大楼,我们用地震第一到达的时间开发一个剥去层的方法。在一个普通中点(CMP)集合以内的速度模型被假定被成层进薄层,并且每层的速度与深度线性地变化。最高的层的厚度和速度在一个CMP集合用最小偏移量的第一到达的数据被估计。然后,最高的层被剥去,第二层成为新最高的层。在把最高的层的效果从以前的第一到达的数据移开以后,新第一到达的数据被获得然后过去常估计第二层的参数。以这种方式,速度模型,是被考虑在一个CMP地点,是从顶的造的layer-by-layer到底部。近表面的速度模型当时是的A3D形成了根本使用速度模型CMP地点。在剥去层的方法能习惯于的合成、观察的地震数据表演的测试造好近表面的速度模型因为静态的修正,和它的计算速度比格子断层摄影术的快约百倍。
