简介：基于BLT（BaumLiuTesche）方程,并考虑入射角、极化方向和爆高对线缆耦合效应的影响,对高空核电磁脉冲（HEMP）作用下线缆终端的耦合电流进行了计算,统计得到不同磁倾角下线缆终端耦合电流的变化规律以及峰值电流的概率分布。结果表明,磁倾角较小的地区更易出现高峰值电流的小概率事件,且随着爆高的增加,高峰值电流事件出现的概率会有所增加。

简介：建设有中国特色社会主义,制度的现代化刻不容缓.制度建设是个系统工程,一个良好的制度应该成为社会制度系统的有机组成部分,它和系统处于功能耦合状态.一个单位如果不顾社会制度系统的耦合需要,各自为政,制度失调,那么,不管经济效益如何,该单位的整体效益是十分有限的.研究制度的功能耦合,有助于单位主体有机地融入社会发展的轨道,实现可持续发展.

简介：数值模拟中，欧拉方法能计算大变形流场，但不能精确地区分物质界面，拉氏方法的单元边界即为物质边界，因此可以精确区分不同的物质，但当计算单元变形较大时计算精度变差甚至无法进行。如果在流场内不同区域采用不同的计算方法，在计算区域交界处进行合理的数据交换，则既能计算大变形流场又能在流场内保持清晰的物质界面。

简介：AbstractMucormycosis is a lethal human disease caused by fungi of the order Mucorales. Mucormycosis is caused by fungi mainly belonging to the genera Mucor, Rhizopus, and Lichtheimia, all of which belong to the order Mucorales. The number of individuals with mucormycosis-causing disorders has increased in recent years, hence, leading to the spread of mucormycosis. Throughout the coronavirus disease 2019 (COVID-19) pandemic, numerous cases of mucormycosis in COVID-19-infected patients have been reported worldwide, and the illness is now recognized as COVID-19-associated mucormycosis, with most of the cases being reported from India. Immunocompromised patients such as those with bone marrow sickness and uncontrolled diabetes are at a greater risk of developing mucormycosis. Genes, pathways, and other mechanisms have been studied in Mucorales, demonstrating a direct link between virulence and prospective therapeutic and diagnostic targets. This review discusses several proteins such as high-affinity iron permease (FTR1), calcineurin, spore coat protein (CotH), and ADP-ribosylation factors involved in the pathogenesis of mucormycosis that might prove to be viable target(s) for the development of novel diagnostic and therapeutic methods.

简介：AbstractBackground:The End Tuberculosis (TB) Strategy of the World Health Organization highlights the need for patient-centered care and social protection measures that alleviate the financial hardships faced by many TB patients. In China, TB treatments are paid for by earmarked government funds, social health insurance, medical assistance for the poor, and out-of-pocket payments from patients. As part of Phase III of the China-Gates TB project, this paper introduces multi-source financing of TB treatment in the three provinces of China and analyzes the challenges of moving towards universal coverage and its implications of multi-sectoral engagement for TB care.Main text:The new financing policies for TB treatment in the three provinces include increased reimbursement for TB outpatient care, linkage of TB treatment with local poverty alleviation programs, and use of local government funds to cover some costs to reduce out-of-pocket expenses. However, there are several challenges in reducing the financial burdens faced by TB patients. First, medical costs must be contained by reducing the profit-maximizing behaviors of hospitals. Second, treatment for TB and multi-drug resistant TB (MDR-TB) is only available at county hospitals and city or provincial hospitals, respectively, and these hospitals have low reimbursement rates and high co-payments. Third, many patients with TB and MDR-TB are at the edge of poverty, and therefore ineligible for medical assistance, which targets extremely poor individuals. In addition, the local governments of less developed provinces often face fiscal difficulties, making it challenging to use of local government funds to provide financial support for TB patients. We suggest that stakeholders at multiple sectors should engage in transparent and responsive communications, coordinate policy developments, and integrate resources to improve the integration of social protection schemes.Conclusions:The Chinese government is examining the establishment of multi-source financing for TB treatment by mobilization of funds from the government and social protection schemes. These efforts require strengthening the cooperation of multiple sectors and improving the accountability of different government agencies. All key stakeholders must take concrete actions in the near future to assure significant progress toward the goal of alleviating the financial burden faced by TB and MDR-TB patients.
