2Distribution of organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) in surface water and sediments from Baiyangdian Lake in North China显示文摘Persistent organochlorine compounds,including hexachlorocyclohexanes (HCHs),dichlorodiphenyltrichloroethanes (DDTs) and polychlorinated biphenyls (PCBs) were analyzed in surface water and sediments from Baiyangdian Lake,North China.Total concentrations of HCHs,DDTs and PCBs in surface water were in the range of 3.13-10.60,4.05-20.59 and 19.46-131.62 ng/L,respectively,and total concentrations of HCHs,DDTs and PCBs in sediments were 1.75-5.70,0.91-6.48 and 5.96-29.61 ng/g dry weight,respectively.Among the groups of HCHs (sum of α-HCH,β-HCH,γ-HCH and δ-HCH) and DDTs (sum of DDT,DDD and DDE),the predominance of β-HCH,DDE and DDD in water and sediment samples was clearly observed.This observation suggested that β-HCH was resistant to biodegradation and the DDTs had been transformed to its metabolites,DDE and DDD.For PCBs,penta-,hexa-and hepta-chlorinated congeners were the most abundant compounds in the both phases.Furthermore,the partitioning of chlorinated compounds between sediment and water was investigated to understand their transport and fates in aquatic ecosystems.The results indicated that average logs of organic carbon-normalized sediment-water partition coefficients (logK'oc) for OCPs varied between 3.20 and 5.53,and for PCBs,logK'oc values ranged from 3.19 to 5.57.The observed logK'oc was lower than their equilibrium logKoc predicted from linear model,which may be attributed to the solubility enhancement effect of colloidal matter in water phase and the disequilibrium between sediment and water.Guohua Dai Xinhui Liu Gang Liang Xu Han Liu Shi Dengmiao Cheng Wenwen Gong 2011Journal of Environmental Sciences2011,23,10:44

4The second natural gas hydrate production test in the South China Sea显示文摘Clayey silt reservoirs bearing natural gas hydrates(NGH)are considered to be the hydrate-bearing reservoirs that boast the highest reserves but tend to be the most difficult to exploit.They are proved to be exploitable by the first NGH production test conducted in the South China Sea in 2017.Based on the understanding of the first production test,the China Geological Survey determined the optimal target NGH reservoirs for production test and conducted a detailed assessment,numerical and experimental simulation,and onshore testing of the reservoirs.After that,it conducted the second offshore NGH production test in 1225 m deep Shenhu Area,South China Sea(also referred to as the second production test)from October 2019 to April 2020.During the second production test,a series of technical challenges of drilling horizontal wells in shallow soft strata in deep sea were met,including wellhead stability,directional drilling of a horizontal well,reservoir stimulation and sand control,and accurate depressurization.As a result,30 days of continuous gas production was achieved,with a cumulative gas production of 86.14×104 m3.Thus,the average daily gas production is 2.87×10^4 m^3,which is 5.57 times as much as that obtained in the first production test.Therefore,both the cumulative gas production and the daily gas production were highly improved compared to the first production test.As indicated by the monitoring results of the second production test,there was no anomaly in methane content in the seafloor,seawater,and atmosphere throughout the whole production test.This successful production test further indicates that safe and effective NGH exploitation is feasible in clayey silt NGH reservoirs.The industrialization of hydrates consists of five stages in general,namely theoretical research and simulation experiments,exploratory production test,experimental production test,productive production test,and commercial production.The second production test serves as an important step from the exploratory production test to experimental production test.Jian-liang Ye Xu-wen Qin Wen-wei Xie Hai-long Lu Bao-jin Ma Hai-jun Qiu Jin-qiang Liang Jing-an Lu Zeng-gui Kuang Cheng Lu Qian-yong Liang Shi-peng Wei Yan-jiang Yu Chunsheng Liu Bin Li Kai-xiang Shen Hao-xian Shi Qiu-ping Lu Jing Li Bei-bei Kou Gang Song Bo Li He-en Zhang Hong-feng Lu Chao Ma Yi-fei Dong Hang Bian 2020China Geology2020,3,2:22
5Active corrosion protection of super-hydrophobic corrosion inhibitor intercalated Mg-Al layered double hydroxide coating on AZ31 magnesium alloy显示文摘Magnesium alloys,the advanced lightweight structural materials,have been successfully applied in the manufacturing field.Unfortunately,their poor corrosion resistance restrains the potential wide applications.In this work,anti-corrosion coatings were fabricated via the insitu growth of the corrosion inhibitors intercalated magnesium-aluminum layered double hydroxide(Mg-Al LDH)on AZ31 magnesium alloy and then post-sealing it by a super-hydrophobic coating.SEM,XRD,EDS,FTIR,XPS and contact angle test were conducted to analyze physical/chemical features of these coatings.Potentiodynamic polarization curves and electrochemical impedance spectroscopy were recorded to assess the anti-corrosion performance of prepared coatings.Surprisingly,Mg-Al LDH with molybdate intercalation and lauric acid modification achieves the excellent corrosion inhibition performance(99.99%)due to the multicomponent synergistic effect such as the physical protection of Mg-Al LDH,the corrosion inhibition of molybdate and super-hydrophobic properties of lauric acid.This work presents a scientific perspective and novel design philosophy to fabricate the efficient anti-corrosion coating to protect magnesium alloys and then expand their potential applications in other field.Xin Wang Chuan Jing Yuxiang Chen Xiushuang Wang Gang Zhao Xing Zhang Liang Wu Xiaoying Liu Biqin Dong Yuxin Zhang 2020Journal of Magnesium and Alloys2020,8,1:20
6Genome and transcriptome analysis of the grapevine(Vitis vinifera L.) WRKY gene family显示文摘The plant WRKY gene family represents an ancient and complex class of zinc-finger transcription factors(TFs)that are involved in the regulation of various physiological processes,such as development and senescence,and in plant response to many biotic and abiotic stresses.Despite the growing number of studies on the genomic organisation of WRKY gene family in different species,little information is available about this family in grapevine(Vitis vinifera L.).In the present study,a total number of 59 putative grapevine WRKY transcription factors(VvWRKYs)were identified based on the analysis of various genomic and proteomic grapevine databases.According to their structural and phylogentic features,the identified grapevine WRKY transcription factors were classified into three main groups.In order to shed light into their regulatory roles in growth and development as well as in response to biotic and abiotic stress in grapevine,the VvWRKYs expression profiles were examined in publicly available microarray data.Bioinformatics analysis of these data revealed distinct temporal and spatial expression patterns of VvWRKYs in various tissues,organs and developmental stages,as well as in response to biotic and abiotic stresses.To also extend our analysis to situations not covered by the arrays and to validate our results,the expression profiles of selected VvWRKYs in response to drought stress,Erysiphe necator(powdery mildew)infection,and hormone treatments(salicilic acid and ethylene),were investigated by quantitative real-time reverse transcription PCR(qRT-PCR).The present study provides a foundation for further comparative genomics and functional studies of this important class of transcriptional regulators in grapevine.Min Wang Alessandro Vannozzi Gang Wang Ying-Hai Liang Giovanni Battista Tornielli Sara Zenoni Erika Cavallini Mario Pezzotti Zong-Ming(Max)Cheng 2014Horticulture Research2014,1,1:19
7Comparison of Undernutrition Prevalence of Children under 5 Years in China between 2002 and 2013显示文摘Objective To describe the undernutrition status of children under 5-year in China, and study the trend between 2002 and 2013. Methods The study was based on two national surveys. Undernutrition was determined against WHO's 2006 growth standards. The prevalence in 2013 and 2002 was weighted by China sixth National Population Census(2010). The relationship between undernutrition and gender/age groups/different areas use weighted logistic regression. Results The results indicated the overall prevalence of stunting, underweight, and wasting of Chinese children under 5-year was 8.1%, 2.4%, and 1.9% in 2013, respectively. The prevalence of stunting was higher for children aged 12-47 month, while underweight was higher for children aged 48-59 month. The prevalence of undernutrition was higher in rural areas than in urban areas, especially in poor rural areas. There was a decline of stunting, underweight, and wasting between 2002 and 2013 among the children, with greater reduction in rural areas than in urban areas. Conclusion The prevalence of undernutrition of children under 5-year remains high in rural areas especially in poor rural areas in China. It is urgent to take action to control undernutrition in the vulnerable areas and subgroups.YU Dong Mei ZHAO Li Yun YANG Zhen Yu CHANG Su Ying YU Wen Tao FANG Hong Yun WANG Xun YU Dan GUO Qi Ya XU Xiao Li FANG Yue Hui ZHAO Wen Hua YANG Xiao Guang DING Gang Qiang LIANG Xiao Feng 2016Biomedical and Environmental Sciences2016,29,3:18
8Effectiveness of Different Waist Circumference Cut-off Values in Predicting Metabolic Syndrome Prevalence and Risk Factors in Adults in China显示文摘Objective To study the effectiveness of waist circumference cut-off values in predicting the prevalence of metabolic syndrome(MetS) and risk factors in adults in China. Methods A cross-sectional survey was condcuted in 14 provinces(autonomous region, municipality) in China. A total of 47 325 adults aged ≥20 years were selected by multistage stratified sampling, and questionnaire survey and physical and clinical examination were conducted among them. MetS was defined according to the International Diabetes Federation(IDF) criteria and modified IDF criteria.Results The age-standardized prevalence of MetS was 24.2%(22.1% in men and 25.8% in women) and 19.5%(22.1% in men and 18.0% in women) according to the IDF criteria and modified IDF criteria respectively. The age-standardized prevalence of pre-MetS was 8.1%(8.6% in men and 7.8% in women) according to the modified IDF criteria. The prevalence of MetS was higher in urban residents than rural residents and in northern China residents than in southern China residents. The prevalence of central obesity was about 30% in both men and women according to the ethnicity-specific cut-off values of waist circumference for central obesity(90 cm for men and 85 cm for women). Multivariate regression analysis revealed no significant difference in risk factors between the two MetS definitions. Conclusion Using both the modified IDF criteria and ethnicity-specific cut-off values of waist circumference can provide more useful information about the prevalence of MetS in China.ZHOU Hai Cheng LAI Ya Xin SHAN Zhong Yan JIA Wei Ping YANG Wen Ying LU Ju Ming WENG Jian Ping JI Li Nong LIU Jie TIAN Hao Ming JI Qiu He ZHU Da Long CHEN Li GUO Xiao Hui ZHAO Zhi Gang Li Qiang ZHOU Zhi Guang GE Jia Pu SHAN Guang Liang 2014Biomedical and Environmental Sciences2014,27,5:17
9HPLC Fingerprint - Antioxidant Properties Study of Buckwheat显示文摘For quality control of buckwheat, fingerprint-efficacy study of buckwheat was carried out in this work. 2,2′-Bipyridyl,2,2- diphenyl-1-picrylhydrazyl radical (DPPH) scavenging activity of the buckwheat was measured using UV spectrometer. Chemical fingerprints of tartary buckwheat from 29 different sources were determined by HPLC-UV and investigated by similarity analysis and hierarchical clustering analysis. The fingerprint-efficacy relationship between chemical fingerprint and DPPH radical scavenging activity of tartary buckwheat were established by multi-linear regression analysis. The results showed that the sources of buckwheat had some important influence on the chemical fingerprints and DPPH radical scavenging activity. DPPH radical scavenging activity of tartary buckwheat was stronger than that of common buckwheat, rutin, and kaempferol and some unknown compound might be the major effective components for quality control of tartary buckwheat for its antioxidant activity.ZHAO Gang PENG Lian-xin WANG Shu HU Yi-bing ZOU Liang 2012Journal of Integrative Agriculture2012,11,7:17

11miRNA targeted signaling pathway in the early stage of denervated fast and slow muscle atrophy显示文摘Denervation often results in skeletal muscle atrophy.Different mechanisms seem to be involved in the determination between denervated slow and fast skeletal muscle atrophy.At the epigenetic level,mi RNAs are thought to be highly involved in the pathophysiological progress of denervated muscles.We used mi RNA microarrays to determine mi RNA expression profiles from a typical slow muscle(soleus muscle) and a typical fast muscle(tibialis anterior muscle) at an early denervation stage in a rat model.Results showed that mi R-206,mi R-195,mi R-23 a,and mi R-30 e might be key factors in the transformation process from slow to fast muscle in denervated slow muscles.Additionally,certain mi RNA molecules(mi R-214,mi R-221,mi R-222,mi R-152,mi R-320,and Let-7e) could be key regulatory factors in the denervated atrophy process involved in fast muscle.Analysis of signaling pathway networks revealed the mi RNA molecules that were responsible for regulating certain signaling pathways,which were the final targets(e.g.,p38 MAPK pathway; Pax3/Pax7 regulates Utrophin and follistatin by HDAC4; IGF1/PI3K/Akt/m TOR pathway regulates atrogin-1 and Mu RF1 expression via Fox O phosphorylation).Our results provide a better understanding of the mechanisms of denervated skeletal muscle pathophysiology.Gang Li Qing-shan Li Wen-bin Li Jian Wei Wen-kai Chang Zhi Chen Hu-yun Qiao Ying-wei Jia Jiang-hua Tian Bing-sheng Liang 2016Neural Regeneration Research2016,11,8:15

13bHLH121 Functions as a Direct Link that Facilitates the Activation of FIT by bHLH IVc Transcription Factors for Maintaining Fe Homeostasis in Arabidopsis显示文摘Iron(Fe)deficiency is prevalent in plants grown in neutral or alkaline soil.Plants have evolved sophisticated mechanisms that regulate Fe homeostasis,ensuring survival.In Arabidopsis,FER-LIKE IRON DEFICIENCY-INDUCED TRANSCRIPTION FACTOR(FIT)is a crucial regulator of Fe-deficiency response.FIT is activated indirectly by basic helix-loop-helix(bHLH)IVc transcription factors(TFs)under Fed eficiency;how ever,it remains unclear which protein(s)act as the linker to mediate the activation of FIT by bHLH IVc TFs.In this study,we characterize the functions of bHLH121 and demonstrate that it directly associates with the FIT promoter.We found that loss-of-function mutations of bHLH121 cause severe Fedeficiency symptoms,reduced Feaccum ulation,and disrupted expression of genes associated with Fehomeostasis.Genetic analysis showed that FIT is epistatic to bHLH121 and FIT overexpression partially rescues the bhlh121 mutant.Further investigations revealed that bHLH IVc TFs interact with and promote nuclear accumulation of bHLH121.We demonstrated that bHLH121 has DNA-binding activity and can bind the prom oters of the FIT and bHLHlb genes,but we did not find that it has either direct transcriptional activation or repression activity tow ard these genes.Meanw hile,we found that bHLH121 functions downstream of and is a direct target of bHLH IVc TFs,and its expression is induced by Fe deficiency in a bHLH IV c-dependent manner.Taken together,these results establish that bHLH121 functions together with bHLH IVc TFs to positively regulate the expression of FIT and thus plays a pivotal role in maintaining Fe homeostasis in Arabidopsis.Rihua Lei Yang Li Yuerong Cai Chenyang Li Mengna Pu Chengkai Lu Yujie Yang Gang Liang 2020Molecular Plant2020,13,4:14

17Arginine, N-carbamylglutamate,and glutamine exert protective effects against oxidative stress in rat intestine显示文摘The objective of the current study is to evaluate the effects of dietary supplementation with arginine(ARG), N-carbamylglutamate(NCG), and glutamine(GLN) on rat intestinal morphology and antioxidant status under oxidative stress. Rats were fed for 30 d with one of the following iso-nitrogenous diets:basal diet(BD), BD plus 1% ARG, BD plus 0.1% NCG, and BD plus 1% GLN. On day 28, half of the rats fed BD were intraperitoneally injected with 12 mg/kg body weight of diquat(DT; i.e., the DT group) and the other half was intraperitoneally injected with sterile solution(i,e., the control group). The other diet groups were intraperitoneally injected with 12 mg/kg body weight of DT(i,e., DT + 1% GLN [DT + GLN],DT + 1% ARG [DT + ARG], and DT + 0.1% NCG [DT + NCG]). Rat jejunum samples obtained at 48 h after DT injection were analyzed. Results showed that DT significantly decreased catalase(CAT) activity and glutathione(GSH) content by 58.25% and 56.57%, respectively, and elevated malondialdehyde(MDA)content and crypt depth(CD) by 19.39% and 22.13%, respectively, in the jejunum(P < 0.05, relative to the control group). Compared with the DT group, the DT + GLN group exhibited significantly improved villus height(VH), villus width(VW), villus surface area(VSA), CD and total antioxidant capacity(T-AOC) activity(P < 0.05); the DT + ARG group exhibited significantly increased the ratio of VH to CD(H:D) and TAOC activity(P < 0.05); the DT + GLN, DT + ARG and DT + NCG groups exhibited significantly enhanced CAT activity and GSH content as well as decreased MDA content(P < 0.05). Moreover, VH, VW, VSA, CD and GSH content in the DT + GLN group were higher whereas MDA content was lower compared with the corresponding values observed in both the DT + ARG and the DT + NCG groups(P < 0.05). The H:D ratio in the DT + ARG group significantly increased compared with that in the DT + NCG and DT + GLN groups(P < 0.05). Collectively, this study suggested that dietary supplementation with 1% GLN, 0.1% NCG,and 1% ARG was effective in enhancing the antioxidant status and maintaining the morphological structure of rat jejunum under oxidative stress; of these supplements, 1% GLN exerted the greatest effects on mitigating oxidative stress.Liang Xiao Wei Cao Guangmang Liu Tingting Fang Xianjian Wu Gang Jia Xiaoling Chen Hua Zhao Jing Wang Caimei Wu Jingyi Cai 2016Animal Nutrition2016,,3:12
18Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event.TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou 2018Science China(Physics,Mechanics & Astronomy)2018,61,3:12
19Some Remarks on Projective Generators and Injective Cogenerators显示文摘In this paper,we give a relationship between projective generators(resp.,injective cogenerators) in the category of R-modules and the counterparts in the category of complexes of R-modules.As a consequence,we get that complexes of W-Gorenstein modules are actually W-Gorenstein complexes whenever W is a subcategory of R-modules satisfying W⊥W,where W is the subcategory of exact complexes with all cycles in W.We also study when all cycles of a W-Gorenstein complexes are W-Gorenstein modules.Li LIANG Nan Qing DING Gang YANG 2014Acta Mathematica Sinica,English Series2014,30,12:11
20The enhanced X-ray Timing and Polarimetry mission—eXTP显示文摘In this paper we present the enhanced X-ray Timing and Polarimetry mission—eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of density, gravity and magnetism. The mission aims at determining the equation of state of matter at supra-nuclear density, measuring effects of QED, and understanding the dynamics of matter in strong-field gravity. In addition to investigating fundamental physics, eXTP will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects. In particular, its wide field monitoring capabilities will be highly instrumental to detect the electro-magnetic counterparts of gravitational wave sources.The paper provides a detailed description of:(1) the technological and technical aspects, and the expected performance of the instruments of the scientific payload;(2) the elements and functions of the mission, from the spacecraft to the ground segment.ShuangNan Zhang Andrea Santangelo Marco Feroci YuPeng Xu FangJun Lu Yong Chen Hua Feng Shu Zhang Sφren Brandt Margarita Hernanz Luca Baldini Enrico Bozzo Riccardo Campana Alessandra De Rosa YongWei Dong Yuri Evangelista Vladimir Karas Norbert Meidinger Aline Meuris Kirpal Nandra Teng Pan Giovanni Pareschi Piotr Orleanski QiuShi Huang Stephane Schanne Giorgia Sironi Daniele Spiga Jiri Svoboda Gianpiero Tagliaferri Christoph Tenzer Andrea Vacchi Silvia Zane Dave Walton ZhanShan Wang Berend Winter Xin Wu Jean J.M.in't Zand Mahdi Ahangarianabhari Giovanni Ambrosi Filippo Ambrosino Marco Barbera Stefano Basso Jörg Bayer Ronaldo Bellazzini Pierluigi Bellutti Bruna Bertucci Giuseppe Bertuccio Giacomo Borghi XueLei Cao Franck Cadoux Francesco Ceraudo TianXiang Chen Yu Peng Chen Jerome Chevenez Marta Civitani Wei Cui WeiWei Cui Thomas Dauser Ettore Del Monte Sergio Di Cosimo Sebastian Diebold Victor Doroshenko Michal Dovciak YuanYuan Du Lorenzo Ducci QingMei Fan Yannick Favre Fabio Fuschino JoséLuis Ga'lvez Min Gao MingYu Ge Olivier Gevin Marco Grassi QuanYing Gu YuDong Gu DaWei Han Bin Hong Wei Hu Long Ji ShuMei Jia WeiChun Jiang Thomas Kennedy Ingo Kreykenbohm Irfan Kuvvetli Claudio Labanti Luca Latronico Gang Li MaoShun Li Xian Li Wei Li ZhengWei Li Olivier Limousin HongWei Liu XiaoJing Liu Bo Lu Tao Luo Daniele Macera Piero Malcovati Adrian Martindale Malgorzata Michalska Bin Meng Massimo Minuti Alfredo Morbidini Fabio Muleri Stephane Paltani Emanuele Perinati Antonino Picciotto Claudio Piemonte JinLu Qu Alexandre Rachevski Irina Rashevskaya Jerome Rodriguez Thomas Schanz ZhengXiang Shen LiZhi Sheng JiangBo Song LiMing Song Carmelo Sgro Liang Sun Ying Tan Phil Uttley Bo Wang DianLong Wang GuoFeng Wang Juan Wang LangPing Wang YuSa Wang Anna L.Watts XiangYang Wen Jörn Wilms ShaoLin Xiong JiaWei Yang Sheng Yang YanJi Yang Nian Yu WenDa Zhang Gianluigi Zampa Nicola Zampa Andrzej A.Zdziarski AiMei Zhang ChengMo Zhang Fan Zhang Long Zhang Tong Zhang Yi Zhang XiaoLi Zhang ZiLiang Zhang BaoSheng Zhao ShiJie Zheng Yu Peng Zhou Nicola Zorzi J.Frans Zwart 2019Science China(Physics,Mechanics & Astronomy)2019,62,2:11
