2Constrained large-eddy simulation and detached eddy simulation of flow past a commercial aircraft at 14 degrees angle of attack显示文摘With the development of computational power and numerical algorithms,computational fluid dynamics(CFD) has become an important strategy for the design of aircraft,which significantly reduces the reliance on wind-tunnel and flight tests.In this paper,we conducted a numerical investigation on the flow past a full commercial aircraft at Mach number 0.2 and 14 degrees angle of attack by means of Reynolds-averaged Navier-Stokes(RANS),detached-eddy simulation(DES) and our newly developed constrained large-eddy simulation(CLES).The objective of this paper is to study the capability of these models in simulating turbulent flows.To our knowledge,this is the first large-eddy simulation method for full commercial aircraft simulation.The results show that the CLES can predict the mean statistical quantities well,qualitatively consistent with traditional methods,and can capture more small-scale structures near the surface of the aircraft with massive separations.Our study demonstrates that CLES is a promising alternative for simulating real engineering turbulent flows.CHEN ShiYi CHEN YingChun XIA ZhenHua QU Kun SHI YiPeng XIAO ZuoLi LIU QiuHong CAI QingDong LIU Feng LEE Cunbiao ZHANG RiKui CAI JinSheng 2013Science China(Physics,Mechanics & Astronomy)2013,56,2:14
3Curative effect of scraping therapies on lumbar muscle strain显示文摘OBJECTIVE:To explore factors influencing the curative effect of scraping therapies (at acupoints or along channels) and to determine the relationship of scraping site and strength to curative effect. METHODS: Two hundred and ten patients with lumbar muscle strain were divided into five groups with 42 patients each.The 'scraping therapy at acupoint until appearance of skin eruptions' and 'scraping therapy along channel until appearance of skin eruptions' groups were treated with a 4-daycourse. The 'scraping therapy at acupoint without appearance of skin eruptions', 'scraping therapy along channel without appearance of skin eruptions', and acupuncture groups were treated with a 2-day course.The five groups were treated with seven courses. The visual analog scale (VAS), oswestry disability index (ODI), and lumbago scores were recorded in the five groups before treatment, after each treatment, and in follow-up visits one month and three months after treatment. RESULTS: VAS, ODI, and lumbago scores after treatment improved in the five groups (P<0.01). There was a statistical difference (P<0.01) in the change of VAS scores by appearance of skin eruptions and scraping site. CONCLUSION: Scraping therapy can effectively alleviate lumbago symptoms. The appearance of skin eruptions and scraping therapy along channels can enhance the curative effect of scraping therapy.Yingying Wang Li Yang Jinsheng Yang Jinhong Yang Zhibin Liu Feng Chen Dongxia Liu Haiguang Yuan Liang Wang 2013Journal of Traditional Chinese Medicine2013,33,4:7
4Bevacizumab biosimilar LY01008 compared with bevacizumab(Avastin)as first-line treatment for Chinese patients with unresectable,metastatic,or recurrent non-squamous non-small-cell lung cancer:A multicenter,randomized,double-blinded,phase Ⅲ trial显示文摘Background:Previous studies have demonstrated the preclinical pharmacological and toxicological consistency,and clinical pharmacokinetic equivalence of bevacizumab biosimilar LY01008 with reference bevacizumab(Avastin).This randomized controlled trial aimed to compare the efficacy and safety of LY01008 with Avastin in first-line treatment of Chinese patients with advanced or recurrent non-squamous non-small cell lung cancer(NSCLC).Methods:StageⅢB-ⅣNSCLC patients with evaluable lesions,good physical status,and adequate organ functions from 67 centers across China were randomized in a ratio of 1:1 to receive LY01008 or Avastin 15 mg/kg intravenously in combination with paclitaxel/carboplatin(combined treatment)for 4-6 cycles,followed by maintenance monotherapy with LY01008 until disease progression,intolerable toxicity,or death.The primary endpoint was objective response rate(ORR)in accordance with Response Evaluation Criteria in Solid Tumors(RECIST)version 1.1 confirmed by independent radiological review committees(IRRC).Secondary endpoints included disease control rate(DCR),duration of response(DoR),progression-free survival(PFS),overall survival(OS),and safety.This study was registered in Clinical Trials.gov(NCT03533127).Results:Between December 15^(th),2017,and May 15^(th),2019,a total of 649 patients were randomized to the LY01008(n=324)or Avastin(n=325)group.As of September 25th,2019 for primary endpoint analysis,589 patients received ORR evaluation,with a median number of combined treatment cycles of 5(range 1-6)andmedian duration of treatment of 3.0(range 0.0-5.1)months.ORRof responseevaluable patients in the LY01008 and Avastin groups were 48.5% and 53.0%,respectively.The stratified ORR ratio was 0.91(90%CI 0.80-1.04,within the prespecified equivalence margin of 0.75-1.33).Up to May 15^(th),2020,with a median follow-up of 13.6(range 0.8-28.4)months,no notable differences in DCR,median DoR,median PFS,median OS,and 1-year OS rate were observed between the LY01008 and Avastin groups.There were no clinically meaningful differences in safety and immunogenicity across treatment groups.Conclusions:LY01008 demonstrated similarity to Avastin in terms of efficacy and safety in Chinese patients with advanced or recurrent non-squamous NSCLC.LY01008 combined with paclitaxel/carboplatin is expected to become a new treatment option for unresectable,metastatic,LY01008 and Avastin groups.There were no clinically meaningful differences in safety and immunogenicity across treatment groups.Conclusions:LY01008 demonstrated similarity to Avastin in terms of efficacy and safety in Chinese patients with advanced or recurrent non-squamous NSCLC.LY01008 combined with paclitaxel/carboplatin is expected to become a new treatment option for unresectable,metastatic,or recurrent non-squamous NSCLC patients in the first-line setting.Yuankai Shi Kaijian Lei Yuming Jia Bingqiang Ni Zhiyong He Minghong Bi Xicheng Wang Jianhua Shi Ming Zhou Qian Sun Guolei Wang Dongji Chen Yongqian Shu Lianke Liu Zhongliang Guo Yong Liu Junquan Yang Ke Wang Ke Xiao LinWu Tienan Yi Debin Sun Mafei Kang Tianjiang Ma Yimin Mao Jinsheng Shi Tiegang Tang Yan Wang Puyuan Xing Dongqing Lv Wangjun Liao Zhiguo Luo Bin Wang Xiaohong Wu Xiaoli Zhu Shuhua Han Qisen Guo Rongyu Liu Zhiwei Lu Jianyong Zhang Jian Fang Changlu Hu Yinghua Ji Guolong Liu Hong Lu Dedong Wu Junhong Zhang Shuyang Zhu Zheng Liu Wensheng Qiu Feng Ye Yan Yu Yanqiu Zhao Qinhong Zheng Jun Chen Zhanyu Pan Yiping Zhang Wenjuan Lian Bo Jiang Bo Qiu Guojun Zhang Hua Zhang Yanju Chen Yuan Chen Hongbing Duan Manxiang Li Shengming Liu Lijun Ma Hongming Pan Xia Yuan Xueli Yuan Yulong Zheng Emei Gao Li Zhao Shumin Wang Can Wu 2021Cancer Communications2021,41,9:5

6Digital Design and Manufacture of Spatial Cams显示文摘In order to design and manufacture spatial cams rapidly and precisely,a CAD/CAM system is introduced for the design of 3D modeling and automatic programming in NC machining. Based on Pro/ENGINEER software used widely in CAD/CAM systems,according to the curve equation of spatial cam follower’s motion specification,the follower displacement curve is drawn quickly and accurately,then the 3D modeling of spatial cam is created using Pro/Feature module in accordance with this curve,afterwards,the quality of contour surface of spatial cam is inspected by the use of surface analysis,the result of which is fed back to the modeling design of spatial cam; after analyzing the machined theory of spatial cam,the NC machining code for it is programmed automatically according to this theory and the modeling completed in the Pro/Manufacture module. To design and manufacture spatial cams by this process can be modified circularly on the basis of the surface checking information in terms of feedback data,so the contour surfaces created have high precision,excellent kinematic characteristics and dynamic characteristics.GE Zhenghao,XU Feng,YANG Fulian,LIANG Jinsheng (Shanxi University of Science & Technology,Xianyang 712081,China) 2006武汉理工大学学报2006,28,S1:3
7Research progress and prospect of plugging technologies for fractured formation with severe lost circulation显示文摘By reviewing the mechanisms of drilling fluid lost circulation and its control in fractured formations, the applicability and working mechanisms of different kinds of lost circulation materials in plugging fractured formations have been summarized. Meanwhile, based on the types of lost circulation materials, the advantages, disadvantages, and application effects of corresponding plugging technologies have been analyzed to sort out the key problems existing in the current lost circulation control technologies. On this basis, the development direction of plugging technology for severe loss have been pointed out. It is suggested that that the lost circulation control technology should combine different disciplines such as geology, engineering and materials to realize integration, intelligence and systematization in the future. Five research aspects should be focused on:(1) the study on mechanisms of drilling fluid lost circulation and its control to provide basis for scientific selection of lost circulation material formulas, control methods and processes;(2) the research and development of self-adaptive lost circulation materials to improve the matching relationship between lost control materials and fracture scales;(3) the research and development of lost circulation materials with strong retention and strong filling in three-dimensional fracture space, to enhance the retention and filling capacities of materials in fractures and improve the lost circulation control effect;(4) the research and development of lost circulation materials with high temperature tolerance, to ensure the long-term plugging effect of deep high-temperature formations;(5) the study on digital and intelligent lost circulation control technology, to promote the development of lost circulation control technology to digital and intelligent direction.SUN Jinsheng BAI Yingrui CHENG Rongchao LYU Kaihe LIU Fan FENG Jie LEI Shaofei ZHANG Jie HAO Huijun 2021Petroleum Exploration and Development2021,48,3:2
8Review of drought impacts on carbon cycling in grassland ecosystems显示文摘Grasslands play a key role in both carbon and water cycles.In semi-arid and arid grassland areas,the frequency and intensity of droughts are increasing.However,the influence of a drought on grassland carbon cycling is still unclear.In this paper,the relationship between drought and grassland carbon cycling is described from the perspective of drought intensity,frequency,duration,and timing.Based on a large amount of literature,we determined that drought is one of the most prominent threats to grassland carbon cycling,although the impacts of different drought conditions are uncertain.The effects of a drought on grassland carbon cycling are more or less altered by drought-induced disturbances,whether individually or in combination.Additionally,a new conceptual model is proposed to better explain the mechanism of droughts on grassland carbon cycling.At present,evaluations of the effects of droughts on grassland carbon cycling are mainly qualitative.A data fusion model is indispensable for evaluating the fate of carbon cycling in a sustainable grassland system facing global change.In the future,multi-source data and models,based on the development of single and multiple disturbance experiments at the ecosystem level,can be utilized to systematically evaluate drought impacts on grassland carbon cycling at different timescales.Furthermore,more advanced models should be developed to address extreme drought events and their consequences on energy,water,and carbon cycling.Tianjie LEI Jie FENG Cuiying ZHENG Shuguang LI Yang WANG Zhitao WU Jingxuan LU Guangyuan KAN Changliang SHAO Jinsheng JIA Hui CHENG 2020Frontiers of Earth Science2020,14,2:2

11The Lifting Scheme Based on the Second Generation Wavelets显示文摘The lifting scheme is a custom-design construction of Biorthogonal wavelets, a fast and efficient method to realize wavelet transform,which provides a wider range of application and efficiently reduces the computing time with its particular frame. This paper aims at introducing the second generation wavelets,begins with traditional Mallat algorithms, illustrates the lifting scheme and brings out the detail steps in the construction of Biorthogonal wavelets. Because of isolating the degrees of freedom remaining the biorthogonality relations, we can fully control over the lifting operators to design the wavelet for a particular application, such as increasing the number of the vanishing moments.FENG Hui GUO Lanying XIAO Jinsheng 2006Wuhan University Journal of Natural Sciences2006,11,3:1
12Ground-layer adaptive optics for the New Vacuum Solar Telescope:Instrument description and first results显示文摘Ground-layer adaptive optics(GLAO)has shown its potential for use in solar observation owing to its wide field-of-view(FOV)correction.A high-order GLAO system that consists of a multiple direction Shack-Hartmann wavefront sensor(WFS),a realtime controller with a multi-CPU processor,and a 151-element deformable mirror was developed for the 1-m New Vacuum Solar Telescope at Yunnan Observatories,Chinese Academy of Sciences.A hexagonal microlens with 9×8 subapertures is employed in the WFS.The detection FOV is 42′′×37′′,in which 9(3×3)guide regions are extracted for multiple direction wavefront sensing with a frame rate of up to 2200 Hz.To our knowledge,this is the first professional solar GLAO system used as a regularly operating instrument for scientific observations.Its installation and adjustment were performed in the summer of 2021.In this article,a detailed account of the GLAO system and its first light results and a comprehensive analysis of the performance of the GLAO system are provided.The results show that this system can effectively improve the imaging quality after compensating for the wavefront aberration due to ground-layer turbulence.Lanqiang Zhang Hua Bao Xuejun Rao Youming Guo Libo Zhong Xian Ran Nanfei Yan Jinsheng Yang Cheng Wang Jiahui Zhou Ying Yang Yunyao Long Xinlong Fan Zhongyi Feng Donghong Chen Changhui Rao 2023Science China(Physics,Mechanics & Astronomy)2023,66,6:1
