1First light of the 1.8-m solar telescope–CLST显示文摘Large-aperture solar telescopes play an important role in solar observations and research,and require high temporal and spatial resolution[1].To solve some fundamental problems such as the solar dynamo,coronal heating,and the triggering of major solar eruptions,the spatial resolution for solar-atmosphere observation should reach at least 0.1 arcsec[2].ChangHui Rao NaiTing Gu XueJun Rao Cheng Li LanQiang Zhang JinLong Huang Lin Kong Ming Zhang YunTao Cheng Yi Pu Hua Bao YouMing Guo YangYi Liu JinSheng Yang LiBo Zhong ChangJun Wang Kai Fang XiaoJun Zhang DongHong Chen Cheng Wang XinLong Fan ZhiWu Yan KeLe Chen XiYa Wei Lei Zhu Hong Liu YongJian Wan Hao Xian WenLi Ma 2020Science China(Physics,Mechanics & Astronomy)2020,63,10:6
2Bottom hole pressure estimation using hybridization neural networks and grey wolves optimization显示文摘An effective design and optimum production strategies of a well depend on the accurate prediction of its bottom hole pressure(BHP)which may be calculated or determined by several methods.However,it is not practical technically or economically to apply for a well test or to deploy a permanent pressure gauge in the bottom hole to predict the BHP.Consequently,several correlations and mechanistic models based on the knownsurfacemeasurementshave beendeveloped.Unfortunately,all these tools(correlations&mechanistic models)are limited to some conditions and intervals of application.Therefore,establish a global model that ensures a large coverage of conditions with a reduced cost and high accuracy becomes a necessity.In this study,we propose new models for estimating bottom hole pressure of vertical wells with multiphase flow.First,Artificial Neural Network(ANN)based on back propagation training(BP-ANN)with 12 neurons in its hidden layer is established using trial and error.The next methods correspond to optimized or evolved neural networks(optimize the weights and thresholds of the neural networks)with Grey Wolves Optimization(GWO),and then its accuracy to reach the global optima is compared with 2 other naturally inspired algorithms which are the most used in the optimization field:Genetic Algorithm(GA)and Particle Swarms Optimization(PSO).The models were developed and tested using 100 field data collected from Algerian fields and covering a wide range of variables.The obtained results demonstrate the superiority of the hybridization ANN-GWO compared with the 2 other hybridizations or with the BP learning alone.Furthermore,the evolved neural networks with these global optimization algorithms are strongly shown to be highly effective to improve the performance of the neural networks to estimate flowing BHP over existing approaches and correlations.Menad Nait Amar Nourddine Zeraibi Kheireddine Redouane 2018Petroleum2018,4,4:4
3Early renal failure as a cardiovascular disease:Focus on lipoprotein(a) and prothrombotic state显示文摘Patients with renal failure are at increased risk of cardiovascular events even at the earliest stages of disease.In addition to many classic cardiovascular risk factors,many conditions that are commonly identified as emerging risk factors might contribute to occurrence of cardiovascular disease.Changes in circulating levels of many of these emerging risk factors have been demonstrated in patients with early stages of renal failure caused by different types of renal disease and have been associated with detection of cardiovascular complications.However,for most of these factors evidence of benefits of correction on cardiovascular outcome is missing.In this article,we comment on the role of lipoprotein(a) and prothrombotic factors as potential contributors to cardiovascular events in patients with early renal failure.Cristiana Catena Gian Luca Colussi Francesca Nait Francesca Pezzutto Flavia Martinis Leonardo A Sechi 2015World Journal of Nephrology2015,4,3:4
4EAST-Educational Adaptive-optics Solar Telescope显示文摘For the public having a better understanding of solar activities,the Educational Adaptive-optics Solar Telescope(EAST)was built in July 2021 and is located at the Shanghai Astronomy Museum.The EAST consists of a 65 cm aperture solar telescope with a 177-element adaptive optics system and two-channel high resolution imaging system at the Hαand TiO bands,in addition to three full disk solar telescopes at CaK,Hαand TiO bands equipped on the tube of the main telescope.In this paper,the configuration of the EAST is described.Its performance and on-sky observational results are presented.The EAST,to our knowledge,is the most advanced solar telescope for the popularization of science in the world.Due to its excellent performance,the data acquired by the EAST can also be used for research on solar physics and space weather prediction.Changhui Rao Xuejun Rao Zhimao Du Hua Bao Cheng Li Jinlong Huang Youming Guo Libo Zhong Qing Lin Xin Ge Jinsheng Yang Xinlong Fan Yangyi Liu Dan Jia Xin Li Mei Li Ming Zhang Yuntao Cheng Jiahui Zhou Jiawen Yao Lanqiang Zhang Naiting Gu 2022Research in Astronomy and Astrophysics2022,22,6:3
5高血压患者同型半胱氨酸水平升高与代谢综合征和心血管事件相关显示文摘高同型半胱氨酸(homocysteine,Hcy)血症和代谢综合征(metabolic syndrome,MS)是明确的心血管危险因素,常与高血压相关。然而血浆Hcy与MS、胰岛素抵抗相关性存在争议,且在高血压患者中的研究较少。该研究探讨高血压患者Hcy与MS和心脑血管事件的相关性。Catena C Colussi G Nait F Capobianco F Sechi LA 陈云 叶鹏 2016中华高血压杂志2016,24,1:2
