Middle East respiratory syndrome coronavirus: current situation and travel-associated concerns

《医学前沿（英文）》 2016年 第10卷 第2期   页码 111-119 doi: 10.1007/s11684-016-0446-y

摘要：

The emergence of Middle East respiratory syndrome coronavirus (MERS-CoV) in 2012 brought back memories of the occurrence of severe acute respiratory syndrome coronavirus (SARS-CoV) in 2002. More than 1500 MERS-CoV cases were recorded in 42 months with a case fatality rate (CFR) of 40%. Meanwhile, 8000 cases of SARS-CoV were confirmed in six months with a CFR of 10%. The clinical presentation of MERS-CoV ranges from mild and non-specific presentation to progressive and severe pneumonia. No predictive signs or symptoms exist to differentiate MERS-CoV from community-acquired pneumonia in hospitalized patients. An apparent heterogeneity was observed in transmission. Most MERS-CoV cases were secondary to large outbreaks in healthcare settings. These cases were secondary to community-acquired cases, which may also cause family outbreaks. Travel-associated MERS infection remains low. However, the virus exhibited a clear tendency to cause large outbreaks outside the Arabian Peninsula as exemplified by the outbreak in the Republic of Korea. In this review, we summarize the current knowledge about MERS-CoV and highlight travel-related issues.

《能源前沿（英文）》 2020年 第14卷 第1期   页码 42-56 doi: 10.1007/s11708-017-0486-2

摘要： Oil and fossil fuels, the main source of energy in the Middle East have obviously the most destructive effects on the environment and public health. The developed countries of the Middle East are faced with the crisis and energy security. This paper is about evaluating the energy demand /consumption in the Middle East. First, the position of energy consumption in the world and the Middle East is discussed. Next, the evaluation of the current potential of clean energy production from renewable energies is explained. Finally, according to related maps, charts and information presented for the condition of renewable energy which has been approved by the countries of the Middle East, the greatest places in some countries of this region are introduced and discussed.

我国西部天然气东输的可行性

邱中建

《中国工程科学》 1999年 第1卷 第1期   页码 94-98

摘要：

我国西部天然气资源十分丰富，占全国天然气总资源量的75%、探明储量的80%，已累计探明储量达13 110×108m3,西部地区已有能力长期稳定年外输气150×108m3。西气东输塔里木天然气有决定意义，目前正在评价的新发现的两个大型气田预计可迅速新增天然气探明储量约5 000×108m3。这些气田储量丰度大，单井产量高，采气成本低。东部长江三角洲地区经济发达，能源短缺，自给率仅为13%，目前能源消费构成中煤炭占76%，城市环境污染严重，是天然气消费的巨大市场。预计2010年天然气需要量253×108m3。西气东输有两个方案，一是塔里木气单独东输，开始年输量100×108m3，第八年开始增加至150×108m3；二是西部诸盆地联合东输，开始年输量150×108m3，第八年开始增加至230×108m3。两个方案均有经济效益，以联合东输方案优点较多。天然气在上海门站每立方米的销售价为1.2～1.3元，是很有竞争力的。项目一旦启动，对东部及西部地区均会带来巨大的好处。

《医学前沿（英文）》 2019年 第13卷 第1期   页码 126-130 doi: 10.1007/s11684-017-0603-y

摘要： Infection with Middle East respiratory syndrome coronavirus (MERS-CoV) emerged in 2012 as an important respiratory disease with high fatality rates of 40%–60%. Despite the increased number of cases over subsequent years, the number of pediatric cases remained low. A review of studies conducted from June 2012 to April 19, 2016 reported 31 pediatric MERS-CoV cases. In this paper, we present the clinical and laboratory features of seven patients with pediatric MERS. Five patients had no underlying medical illnesses, and three patients were asymptomatic. Of the seven cases, four (57%) patients sought medical advice within 1–7 days from the onset of symptoms. The three other patients (43%) were asymptomatic and were in contact with patients with confirmed diagnosis of MERS-CoV. The most common presenting symptoms were fever (57%), cough (14%), shortness of breath (14%), vomiting (28%), and diarrhea (28%). Two (28.6%) patients had platelet counts of<150 × 10 /L, and one patient had an underlying end-stage renal disease. The remaining patients presented with normal blood count, liver function, and urea and creatinine levels. The documented MERS-CoV Ct values were 32–38 for four of the seven cases. Two patients (28.6%) had abnormal chest radiographic findings of bilateral infiltration. One patient (14.3%) required ventilator support, and two patients (28.6%) required oxygen supplementation. All the seven patients were discharged without complications.

《能源前沿（英文）》 2016年 第10卷 第4期   页码 375-381 doi: 10.1007/s11708-016-0426-6

摘要： Globally, solar energy is expected to play a significant role in the changing face of energy economies in the near future. However, the variability of this resource has been the main barrier for solar energy development in most locations around the world. This paper investigated the distribution and variability of solar radiation using the a 10-year (2006 to 2015) data collected at Sørås meteorological station located at latitude 59° 39′ N and longitude 10° 47′E, about 93.3 m above sea level (about 30 km from Oslo), in south-eastern part of Norway. It is found that on annual basis, the total number of days with a global solar radiation of less than 1 kWh/(m ·d) is 120 days while the total number of days with an expected global solar radiation greater than 3 kWh/(m ·d) is 156 days (42.74%) per year. The potential energy output from a horizontally placed solar collector in these 156 days is approximately 75% of the estimated annual energy output. In addition, it is found that the inter-annual coefficient of variation of the global solar radiation is 4.28%, while that of diffuse radiation is 4.96%.

Middle East respiratory syndrome coronavirus: a comprehensive review

null

《医学前沿（英文）》 2016年 第10卷 第2期   页码 120-136 doi: 10.1007/s11684-016-0430-6

摘要：

The Middle East respiratory syndrome coronavirus was first identified in 2012 and has since then remained uncontrolled. Cases have been mostly reported in the Middle East, however travel-associated cases and outbreaks have also occurred. Nosocomial and zoonotic transmission of the virus appear to be the most important routes. The infection is severe and highly fatal thus necessitating rapid and efficacious interventions. Here, we performed a comprehensive review of published literature and summarized the epidemiology of the virus. In addition, we summarized the virological aspects of the infection and reviewed the animal models used as well as vaccination and antiviral tested against it.

基于最小二乘法的EAST托卡马克光学等离子体边缘重建 None

Hao LUO, Zheng-ping LUO, Chao XU, Wei JIANG

《信息与电子工程前沿（英文）》 2018年 第19卷 第9期   页码 1124-1134 doi: 10.1631/FITEE.1700041

摘要： 重建等离子体位形是托卡马克装置中一个非常重要的课题。平衡与反演编码（equilibrium and fitting, EFIT）是部分托卡马克中常用的等离子体边缘重建方法。然而，这种磁方法有一些不可避免的缺点。提出一种光学等离子体边缘重建算法，将EFIT编码结果作为标准值学习光学重建模型。在边缘提取方面，传统边缘检测方法不能提取较清晰的等离子体边缘。因此，提出一种基于全局对比度的方法在图像平面提取等离子体边缘。这种方法对光照有很好的鲁棒性。用一个同阶多项式和一个转换矩阵拟合提取等离子体边缘和EFIT重建等离子体边缘。为在没有相机标定的前提下获取转换矩阵，用最小二乘法最小化光学边缘和EFIT重建边缘误差，得到一个数学模型，该数学模型将提取的等离子体边缘从一个图像平面转换到托卡马克极向平面。一旦获得这个转换矩阵，便可在捕获的任意图像重建光学等离子体边缘。展示了所提方法和EFIT之间的误差，并讨论不同多项式阶数的实验结果。

《环境科学与工程前沿（英文）》 2022年 第16卷 第1期   页码 10-10 doi: 10.1007/s11783-021-1444-0

摘要：

In view of increasing Microplastics (MPs) contamination in the marine environment and dearth of baseline data, a study was conducted on the abundance, characterization, and seasonal distribution of MPs in the nearshore sediments of the south-east coast of India. Sediment samples (n = 130) were collected at a distance of 1 km and 10 km from the shore region at varying depths (8–45 m) along the Chennai to Puducherry coast (165 km stretch), representing two seasons, i.e., south-west (July 2019 and July 2020) and north-east (January 2020) monsoons. The average abundance of MPs at the 22 offshore sites along the Chennai to Puducherry coast varied from 9±4.3 to 19±12.9 particles/50 g dry weight, in July 2019 and January 2020, respectively. July 2020 had an average abundance of 10±4.5 particles/50 g dry weight. Spatially, high levels of MPs were found at 1km stations and transects in proximity to the river inlets, and temporally, the north-east month recorded the maximum concentration. The dominant morphotype was the filament, and the major polymers were polyethylene and polypropylene. Scanning Electron Microscope (SEM) images revealed the surface irregularity and degradation of MPs due to weathering. The study highlights that high sediment contamination by MPs occurs during heavy rainfall and accumulates closer to river inlets. Eventually, this study suggests that appropriate management of plastic wastes on the landside will reduce MP contamination in the marine environment.
