1Ridge subduction and porphyry copper-gold mineralization:An overview显示文摘Many large porphyry Cu-Au deposits are connected to adakitic rocks known to be closely associated with ridge subduction. For example, there are several subducting ridges along the east Pacific margin, e.g., in Chile, Peru, and South America, most of which are associated with large porphyry Cu-Au deposits. In contrast, there are much fewer ridge subductions on the west Pacific margin and porphyry Cu-Au deposits are much less there, both in terms of tonnage and the number of deposits. Given that Cu and Au are moderately incompatible elements, oceanic crust has much higher Cu-Au concentrations than the mantle and the continental crust, and thus slab melts with their diagnostic adakitic chemistry have systematically higher Cu and Au, which is favorable for mineralization. Considering the geotherm of subducting slabs in the Phanerozoic, ridge subduction is the most favorable tectonic setting for this. Therefore, slab melting is the likely link in the spatial association between ridge subduction and Cu-Au deposits. Geochemical signatures of slab melting and hence maybe ridge subduction in less eroded regions in eastern China, the central Asian orogenic belt etc. may indicate important exploration targets for large porphyry Cu-Au deposits.SUN WeiDong LING MingXing YANG XiaoYong FAN WeiMing DING Xing LIANG HuaYing 2010Science China Earth Sciences2010,53,4:97
2Stability analysis of the temperature cracks in Xiaowan arch dam显示文摘In the Xiaowan arch dam there are massive temperature cracks nearly parallel to the dam axis. Obviously, whether the cracks may spread or not during the water storage process is one of the crucial factors for the safety of a dam. In this paper, a new type of crack element, in which the contact component is implicitly included into the concrete component, is proposed to simulate the effects of the existing cracks. The crack element is proved by numerical example to share the merits of both conventional contact elements and joint elements. With a finite element model of the cracked arch dam together with its rock foundation established, the transient displacement and stress fields of the dam are obtained. The complicated rock foundation, the construction process of the arch dam, the massive cracks, the transient temperature field, as well as the water storage process have been taken into consideration in the simulation. In addition to the global model, several sub-models for typical crack tips are also generated with finer elements placed around the tips. Thus, more accurate displacement and stress distribution are obtained by simultaneous sub-model simulation. Based on the calculation of stress intensity factor for crack tips by extension method, the temperature cracks in the Xiaowan arch dam are finally proved to be stable.WANG WeiMing DING JianXin WANG GuoJin ZOU LiChun CHEN ShengHong 2011Science China(Technological Sciences)2011,54,3:12

4溃疡性结肠炎内镜下严重度指数(UCEIS评分)与Mayo内镜评分(MES)用于预测急性重症结肠炎患者行肠切除术的比较研究显示文摘背景溃疡性结肠炎内镜下严重度指数(UCEIS)和Mayo内镜评分(MES)都是溃疡性结肠炎(UC)内镜下严重程度的客观评估方法,然而,对于这两种评分方法能否用于筛选出需要行结肠切除术的急性重症结肠炎患者,目前仍不明了。方法:对2012年1月至2016年5月间连续收治的ASC患者进行回顾性分析。提取并分析入组患者的人口统计资料、既往治疗史、疾病特征资料、实验室指标、药物治疗及内镜评估等资料。主要结局指标是住院和随访期间需行结肠切除术的患者比例。结果:92例患者纳入研究,其中37例(40.2%)需行结肠切除术。多因素分析显示,UCEIS评分是需行结肠切除术的独立预测因素(OR=3.25,95%CI:1.77~5.97;P<0.001)。UCEIS评分的ROC曲线下面积为0.85;以7分作为最佳阈值,其预测需行结肠切除术的敏感度为60.3%,特异度为85.5%。UCEIS评分对于需要行结肠切除术的预测价值优于MES评分,后者曲线下面积仅为0.65。当UCEIS评分≥7分时,有80%的ASC患者最终需行结肠切除术。结论:预测ASC患者的肠切除风险,UCEIS评分优于MES评分。对于USEIS≥7分的患者,由于其药物治疗失败风险较高,因此,可考虑早期行结肠切除术。Tingbin Xie Tenghui Zhang Chao Ding Xujie Dai Yi Li Zhen Guo Yao Wei Jianfeng Gong Weiming Zhu Jieshou Li 2018Gastroenterology Report2018,6,1:6

6Hundred-Joule-level,nanosecond-pulse Nd:glass laser system with high spatiotemporal beam quality显示文摘A 100-J-level Nd:glass laser system in nanosecond-scale pulse width has been constructed to perform as a standard source of high-fluence-laser science experiments. The laser system, operating with typical pulse durations of 3–5 ns and beam diameter 60 mm, employs a sequence of successive rod amplifiers to achieve 100-J-level energy at 1053 nm at3 ns. The frequency conversion can provide energy of 50-J level at 351 nm. In addition to the high stability of the energy output, the most valuable of the laser system is the high spatiotemporal beam quality of the output, which contains the uniform square pulse waveform, the uniform flat-top spatial fluence distribution and the uniform flat-top wavefront.Sensen Li Yulei Wang Zhiwei Lu Lei Ding Yi Chen Pengyuan Du Dexin Ba Zhenxing Zheng Xin Wang Hang Yuan Chengyu Zhu Weiming He Dianyang Lin Yongkang Dong Dengwang Zhou Zhenxu Bai Zhaohong Liu Can Cui 2016High Power Laser Science and Engineering2016,4,1:3
7Validating the deep time carbonate carbon isotope records: effect of benthic flux on seafloor carbonate显示文摘It is a consensus that marine carbonate archives the isotopic composition of seawater dissolved inorganic carbon(DIC,δ13Csw),the largest active C reservoir in the hydrosphere.Carbonate carbon isotope(δ13Ccarb)excursions have been used to reflect perturbations of the global carbon cycle and related environmental change.However,the deep timeδ13Ccarb records indicate faster and more pronounced perturbations of the carbon cycle compared to the present day.Here,we reportδ13Ccarb and elemental compositions of Late Paleozoic carbonate sections from South China,showing negative correlations betweenδ13-Ccarb and Fe^(2+)content of carbonate(Fecarb).We suggest that,because Late Paleozoic carbonate was mainly produced by benthic carbonate-secreting organisms,δ13Ccarbrecorded the isotopic composition near the seafloor,where benthic flux derived from anaerobic organic matter degradation delivers both Fe2+and 13C-depleted DIC from porewater.The binary mixing between seawater and benthic flux would result in the deviation ofδ13Ccarb fromδ13Csw.The negative correlation implies thatδ13Ccarb is influenced by benthic flux and is affected by the seafloor redox and sedimentation rate.The deep time spatially heterogeneous and temporally oscillatoryδ13Ccarb records in the basin-scale could be alternatively attributed to the variations of local environmental factors rather than aδ13Csw depth-gradient.Thus,the seafloor carbonate precipitation is continuously affected by diagenetic reactions in sediments,suggesting thatδ13Ccarb recording the seawater DIC composition is conditional.Our study urges that the interpretation ofδ13Ccarb should also consider the sedimentary process and depositional environment of marine carbonate.Weiming Ding Ting Nie Yongbo Peng Yuanlin Sun Jinzhuang Xue Bing Shen 2021Acta Geochimica2021,40,3:2

9Construction of mesoporous ceria-supported gold catalysts with rich oxygen vacancies for efficient CO oxidation显示文摘Bearing unique redox nature and high oxygen storage capacity,ceria(CeO_(2))has always been a promising CO oxidation catalyst support for gold(Au)catalysts and the like.Herein,a series of Au-CeO_(2)-P(P stands for pH value)samples was prepared by a co-precipitation method with the assistance of an alkaline environment and amino groups functionalized ordered mesoporous polymer(OMP-NH_(2)).Afterward,all samples described above were characterized that the Au-CeO_(2)-P catalysts are made of Au-Ce-O solid solution and Au nanoparticles(NPs)supported on CeO_(2).It turns out that OMP-NH_(2) is not just a simple sacrificial template for mesoporous structure,but also plays an important role as an amino source,explaining the presence of rich oxygen vacancies.Due to the concentration of oxygen vacancies in Au-Ce-O solid solution is the key factor for the oxygen mobility of CO oxidation,the catalytic results also demonstrate that the catalytic activity of Au-CeO_(2)-P catalysts is related to the concentration of their oxygen vacancies.Moreover,Au-CeO_(2)-9.6 with a highest concentration of oxygen vacancies(as high as 13.98%)in Au-CeO_(2)-P catalysts exhibits the best catalytic activity(complete conversion at 10℃).Xin Shen Wang Li Shunmin Ding Xiaohua Ma Shaohua Wu Weiming Xiao Rong Zeng Sanguo Hong Chao Chen 2022Journal of Rare Earths2022,40,3:2
10Dynamic interaction of neutrophils and RFP-labelled Vibrio parahaemolyticus in zebrafish(Danio rerio)显示文摘Vibrio parahaemolyticus(Vp)is an aquatic zoonotic pathogen that causes vibriosis in marine animals as well as sepsis,gastroenteritis and wound infection in human.In vertebrates,the innate immune system plays a critical defense mechanism against Vp infection including transmigration of neutrophils.In this study,we have examined the genetic recombination and infectious process of Vp in the zebrafish(Danio rerio),a vertebrate model system extensively used for studying host-pathogen interactions.A pathogenic Vp strain,Vp57,tagged with red fluorescent protein(RFP)(Vp57^(RFP))was introduced into larval zebrafish at 3 days post fertilization(dpf),in which the innate immunity is present whereas the adaptive immunity has not yet developed.Vp57 and Vp57^(RFP)showed similar LD50 and induced similar symptoms and pathological changes in the hosts.We microinjected 579 colony-forming units(CFU)Vp57^(RFP)into the zebrafish caudal vein,and observed that neutrophils were recruited to the injection site and within 3 h post infection(hpi)Vp57^(RFP)were mainly distributed in the tail,eyes,heart and optic vesicle.After 3 hpi,the fish died with slight spine bending.Several Vp57^(RFP)were also detected in somites,the phagocytosis of neutrophils was activated through the progress of bacterial infections.We found that chemotaxis and phagocytosis of neutrophils occurs when zebrafish is infected by Vp57^(RFP),whereas Vp57^(RFP)can escape from neutrophils and colonize other remote regions using the blood circulation system.Qiuyue Zhang An Ding Qianwen Yue Weiming Li Yao Zu Qinghua Zhang 2017Aquaculture and Fisheries2017,2,6:1

16Estimating the time interval between transmission generations and the presymptomatic period by contact tracing surveillance data from 31 provinces in the mainland of China显示文摘The global pandemic of 2019 coronavirus disease(COVID-19)is a great assault to public health.Presymptomatic transmission cannot be controlled with measures designed for symptomatic persons,such as isolation.This study aimed to estimate the interval of the transmission generation(TG)and the presymptomatic period of COVID-19,and compare the ftting effects of TG and serial interval(S)based on the SEIHR model incorporating the surveillance data of 3453 cases in 31 provinces.These data were allocated into three distributions and the value of AIC presented that the Weibull distribution fitted well.The mean of TG was 5.2 days(95%C:4.6-5.8).The mean of the presymptomatic period was 2.4 days(95%CI:1.5-3.2).The dynamic model using TG as the generation time performed well.Eight provinces exhibited a basic reproduction number from 2.16 to 3.14.Measures should be taken to control presymptomatic transmission in the COVID-19 pandemic.Zhongxing Ding Kai Wang Mingwang Shen Kai Wang Shi Zhao Wenyu Song Rui Li Zhongjie Li Liping Wang Ganzhu Feng Zhiliang Hu Hongxia Wei Yanni Xiao Changjun Bao Jianli Hu Liguo Zhu Yong Li Xufeng Chen Yi Yin Weiming Wang Yongli Cai Zhihang Peng Hongbing Shen 2021Fundamental Research2021,1,2:1
