1Evaluation of Typhoon Waves Simulated by Wave Watch-Ⅲ Model in Shallow Waters Around Zhoushan Islands显示文摘In this study, we simulated typhoon waves in the shallow waters around the Zhoushan Islands using the WaveWatch-Ⅲ(WW3) model version 5.16, the latest version released by the National Oceanic and Atmospheric Administration. Specifically, we used in-situ measurements to evaluate the performance of seven packages of input/dissipation source terms in the WW3 model. We forced the WW3 model by wind fields derived from a combination of the parametric Holland model and high-resolution European Center for Medium-Range Weather Forecasts(ECMWF) wind data in a 0.125? grid, herein called H-E winds. We trained the H-E winds by fitting a shape parameter B to buoy-measured observations, which resulted in a smallest root mean square error(RMSE) of 3 m s^(-1) for B, when treated as a constant 0.4. Then, we applied the seven input/dissipation terms of WW3, labelled ST1, ST2, ST2+STAB2, ST3, ST3+STAB3, ST4, and ST6, to simulate the significant wave height(SWH) up to 5 m during typhoons Fungwong and Chan-hom around the Zhoushan Islands. We then compared the SWHs of the simulated waves with those measured by the in-situ buoys. The results indicate that the simulation using ST2 performs best with an RMSE of 0.79 m for typhoon Fung-wong and an RMSE of 1.12 m for typhoon Chan-hom. Interestingly, we found the simulated SWH results to be relatively higher than those of the observations in the area between Hangzhou Bay and the Zhoushan Islands. This behavior is worthy of further investigation in the future.SHENG Yexin SHAO Weizeng LI Shuiqing ZHANG Yuming YANG Hongwei ZUO Juncheng 2019Journal of Ocean University of China2019,18,2:9
2Assessing the global averaged sea-level budget from 2003 to 2010显示文摘A global mass balance(Greenland and Antarctica ice sheet mass loss,terrestrial water storage)and different sea-level components(observed sea-level from satellite altimetry,steric sea-level from Ishii data,and ocean mass from gravity recovery and climate experiment,GRACE)are estimated,in terms of seasonal and interannual variabilities from 2003 to 2010.The results show that a detailed analysis of the GRACE time series over the time period 2003–2010 unambiguously reveals an increase in mass loss from the Greenland ice sheet and Antarctica ice sheet.The mass loss of both ice sheets accelerated at a rate of(392.8±70.0)Gt/a during 2003–2010,which contributed(1.09±0.19)mm/a to the global mean sea-level during this time.The net terrestrial water storage(TWS)trend was negative over the 8 a time span,which gave a small positive contribution of(0.25±0.12)mm/a.The interannual variability of the global mean sea-level was at least partly caused by year-to-year variability of land water storage.Estimating GRACE-based ice sheet mass balance and terrestrial water storage by using published estimates for melting glaciers,the results further show that the ocean mass increase since 2003 has resulted half from an enhanced contribution of the polar ice sheets,and half from the combined ice sheet and terrestrial water storage loss.Taking also into account the melting of mountain glaciers(0.41 mm/a)and the small GRACE-based contribution from continental waters(0.25 mm/a),a total ocean mass contribution of(1.75±0.57)mm/a from 2003 to 2010 is found.Such a value represented 75%of the altimetry-based rate of sea-level rise over that period.The contributions to steric sea-level(i.e.,ocean thermal expansion plus salinity effects)are estimated from:(1)the difference between altimetry-based sea-level and ocean mass change and(2)the latest Ishii data.The inferred steric sea-level rate from(1)(1.41 mm/a from 2003 to 2010)did not agree well with the Ishii-based value also estimated here(0.44 mm/a from 2003 to 2010),but phase.The cause for such a discrepancy is not yet known but may be related to inadequate sampling of in situ ocean temperature and salinity measurements.LI Juan ZUO Juncheng CHEN Meixiang TAN Wei YANG Yiqiu 2013Acta Oceanologica Sinica2013,32,10:6

4Prediction of China's Submerged Coastal Areas by Sea Level Rise due to Climate Change显示文摘Based on the simulation with the Ocean-Atmosphere Coupled Model CCSM and Ocean Model POP under the greenhouse gas emission scenario of the IPCC SRES A2(IPCC,2001),and on the earth crust subsidence and glacier melting data,the relative sea level change is obtained along the coast of China in the 21st century.Using the SRTM elevation data the submergence of coastal low land is calculated under the extreme water level with a 100-year return period.The total flooding areas are 98.3×103and 104.9×103km2for 2050 and 2080,respectively.For the three regions most vulnerable to extreme sea level rise,i.e.,the coast of Bohai Bay,the Yangtze River Delta together with neighboring Jiangsu Province and northern Zhejiang Province,and the Pearl River Delta,the flooded areas are 5.0×103,64.1×103and 15.3×103km2in 2050 and 5.2×103,67.8×103and 17.2×103km2in 2080,respectively.ZUO Juncheng YANG Yiqiu ZHANG Jianli CHEN Meixiang XU Qing 2013Journal of Ocean University of China2013,12,3:5

6OsbZIP60-mediated unfolded protein response regulates grain chalkiness in rice显示文摘Grain chalkiness,an undesirable trait caused by complex factors,has great negative impacts on the quality and economic value of rice.However,little is known about the regulatory mechanism of grain chalkiness,particularly the effect of endoplasmic reticulum(ER)stress.Here,a genome-wide association study(GWAS)reveals that the transcription factor Osb ZIP60 is a vital regulator of rice grain chalkiness.Genetic analysis demonstrates that knockout of Osb ZIP60 results in extremely high grain chalkiness and aberrant structure of storage substances.Notably,the expression of unfolded protein response(UPR)genes,such as OsbZIP50,Os Bi P1,Os Bi P2 and Os Bi P3,is up-regulated in the endosperm cells of osbzip60,and overexpression of all these UPR genes causes various degrees of chalkiness.Furthermore,Osb ZIP60 is found to activate the expression of key genes related to grain chalkiness,such as GPA3,FSE1,FLO7,Chalk5,Os NF-YB1,and Os PK2,whose expression is significantly suppressed in osbzip60 and overexpression lines of Osb ZIP50,Os Bi P1,Os Bi P2,and Os Bi P3.Our study provides novel insights into the function of Osb ZIP60 and the role of the UPR pathway in the formation of grain chalkiness in rice.Weiping Yang Pengkun Xu Juncheng Zhang Shuo Zhang Zhenwei Li Ke Yang Xinyuan Chang Yibo Li 2022Journal of Genetics and Genomics2022,49,5:4
7Serum semaphorin 4C as a diagnostic biomarker in breast cancer:A multicenter retrospective study显示文摘Background:To date,there is no approved blood-based biomarker for breast cancer detection.Herein,we aimed to assess semaphorin 4C(SEMA4C),a pivotal protein involved in breast cancer progression,as a serum diagnostic biomarker.Methods:We included 6,213 consecutive inpatients from Tongji Hospital,Qilu Hospital,and Hubei Cancer Hospital.Training cohort and two validation cohorts were introduced for diagnostic exploration and validation.A pan-cancer cohort was used to independently explore the diagnostic potential of SEMA4C among solid tumors.Breast cancer patients who underwent mass excision prior to modified radical mastectomy were also analyzed.We hypothesized that increased pretreatment serum SEMA4C levels,measured using optimized in-house enzymelinked immunosorbent assay kits,could detect breast cancer.The endpoints were diagnostic performance,including area under the receiver operating characteristic curve(AUC),sensitivity,and specificity.Post-surgery pathological diagnosis was the reference standard and breast cancer staging followed the TNM classification.There was no restriction on disease stage for eligibilities.Results:We included 2667 inpatients with breast lesions,2378 patients with other solid tumors,and 1168 healthy participants.Specifically,118 patients with breast cancer were diagnosed with stage 0(5.71%),620 with stage I(30.00%),966 with stage II(46.73%),217 with stage III(10.50%),and 8 with stage IV(0.39%).Patients with breast cancer had significantly higher serum SEMA4C levels than benign breast tumor patients and normal controls(P<0.001).Elevated serum SEMA4C levels had AUC of 0.920(95%confidence interval[CI]:0.900–0.941)and 0.932(95%CI:0.911–0.953)for breast cancer detection in the two validation cohorts.The AUCs for detecting early-stage breast cancer(n=366)and ductal carcinoma in situ(n=85)were 0.931(95%CI:0.916–0.946)and 0.879(95%CI:0.832–0.925),respectively.Serum SEMA4C levels significantly decreased after surgery,and the reduction was more striking after modified radical mastectomy,compared with mass excision(P<0.001).The positive rate of enhanced serum SEMA4C levels was 84.77%for breast cancer and below 20.75%for the other 14 solid tumors.Conclusions:Serum SEMA4C demonstrated promising potential as a candidate biomarker for breast cancer diagnosis.However,validation in prospective settings and by other study groups is warranted.Ya Wang Long Qiao Jie Yang Xiong Li Yaqi Duan Jiahao Liu Shaoqi Chen Huayi Li Dan Liu Tian Fang Jingjing Ma Xiaoting Li Fei Ye Junxiang Wan Juncheng Wei Qin Xu Ensong Guo Ping Jin Mingfu Wu Lin Zhang Yun Xia Yaqun Wu Jun Shao Yaojun Feng Qing Zhang Zongyuan Yang Gang Chen Qinghua Zhang Xingrui Li Shixuan Wang Junbo Hu Xiaoyun Wang Mona P.Tan Kazuaki Takabe Beihua Kong Qifeng Yang Ding Ma Qinglei Gao 2021Cancer Communications2021,41,12:3
8Highly green fluorescent Nb2C MXene quantum dots for Cu2+ion sensing and cell imaging显示文摘Niobium carbide MXene quantum dots(Nb2 C MQDs)derived from 2 D Nb2 CTx(MXene)are the rising-star material recently.Herein,a sulfur and nitrogen co-doped Nb2 C MQDs(S,N-MQDs)were synthesized through a hydrothermal method.The obtained Nb2 C MQDs have excellent green fluorescence with a quantum yield(QY)of 17.25%.In addition,they exhibited excitatio n-dependent photoluminescence,antiphotobleaching and dispersion stability.They emit light at 520 nm when excited at 390 nm.The Nb2 C MQDs could be successfully applied to copper ion detection with detection limit of 2μmol/L and Caco-2 cells imaging.Xiang Yan Junfei Ma Kaixuan Yu Jiapeng Li Lei Yang Jjiaqi Liu Juncheng Wang Lulu Cai 2020Chinese Chemical Letters2020,31,12:3
9Obsolescence determination of network information based on “double-proportion” method显示文摘Purpose:It is necessary to determine whether the value of network information exists or not from users’perspective.This study is to develop a new approach,called'double-proportion'method(DPM),to determine the point of information obsolescence.Design/methodology/approach:Firstly,DPM is produced and introduced with statistics in great detail.Secondly,two data sets from Qiangguo Forum and NetEase News are used to validate DPM.Finally,the distributions of lifetime of the two sets are compared and reasons for the differences are revealed.Findings:In Qiangguo Forum,posts with no comments within 17 h can be identified as obsolescence,which indicates that approximately 83%of posts information has died within24 h,92%died within 36 h and almost all died within 54 h;While in NetEase News,news without comments within 28 h can be identified as obsolescence.Research limitations:This study adopted comments as the only behavior indicator,for further study other indicators like page views,republished times need to be used,to exploit better solutions for information obsolescence.Practical implications:According to obsolescence determination,network managers can optimize webpages more rationally,delete aged information in time,preserve valuable information,help search engines ignore aged webpages,optimize reptiles’mechanisms,and help advertisers choose webpages rationally to advertise online.Originality/value:Firstly,DPM is designed from users’perspective to describe the lifetime of information;Secondly,DPM is easy to use.DPM merges and improves former methods by taking the long-tail theory and Pareto principle into consideration.Juncheng WANG Kai YANG Xiang LI Mengxian ZHU 2013Chinese Journal of Library and Information Science2013,,4:2
10Association of assisted reproductive technology, germline de novo mutations and congenital heart defects in a prospective birth cohort study显示文摘Emerging evidence suggests that children conceived through assisted reproductive technology(ART)have a higher risk of congenital heart defects(CHDs)even when there is no family history.De novo mutation(DNM)is a well-known cause of sporadic congenital diseases;however,whether ART procedures increase the number of germline DNM(gDNM)has not yet been well studied.Here,we performed whole-genome sequencing of 1137 individuals from 160 families conceived through ART and 205 families conceived spontaneously.Children conceived via ART carried 4.59 more gDNMs than children conceived spontaneously,including 332 paternal and 1.26 maternal DNMs,after correcting for parental age at conception,cigarette smoking,alcohol drinking,and exercise behaviors.Paternal DNMs in offspring conceived via ART are characterized by C>T substitutions at CpG sites,which potentially affect protein-coding genes and are significantly associated with the increased risk of CHD.In addition,the accumulation of non-coding functional mutations was independently associated with CHD and 87.9% of the mutations were originated from the father.Among ART offspring,infertility of the father was associated with elevated paternal DNMs;usage of both recombinant and urinary follicle-stimulating hormone and high-dosage human chorionic gonadotropin trigger was associated with an increase of maternal DNMs.In sum,the increased gDNMs in offspring conceived by ART were primarily originated from fathers,indicating that ART itself may not be a major reason for the accumulation of gDNMs.Our findings emphasize the importance of evaluating the germline status of the fathers in families with the use of ART.Cheng Wang Hong Lv Xiufeng Ling Hong Li Feiyang Diao Juncheng Dai Jiangbo Du Ting Chen Qi Xi Yang Zhao Kun Zhou Bo Xu Xiumei Han Xiaoyu Liu Meijuan Peng Congcong Chen Shiyao Tao Lei Huang Cong Liu Mingyang Wen Yangqian Jiang Tao Jiang Chuncheng Lu Wei Wu Di Wu Minjian Chen Yuan Lin Xuejiang Guo Ran Huo Jiayin Liu Hongxia Ma Guangfu Jin Yankai Xia Jiahao Sha Hongbing Shen Zhibin Hu 2021Cell Research2021,31,8:2
11Dietary ellagic acid supplementation attenuates intestinal damage and oxidative stress by regulating gut microbiota in weanling piglets显示文摘Intestinal oxidative stress triggers gut microbiota dysbiosis,which is involved in the etiology of postweaning diarrhea and enteric infections.Ellagic acid(EA)can potentially serve as an antioxidant supplement to facilitate weaning transition by improving intestinal oxidative stress and gut microbiota dysbiosis.Therefore,we aimed to investigate the effects of dietary EA supplementation on the attenuation of intestinal damage,oxidative stress,and dysbiosis of gut microbiota in weanling piglets.A total of126 piglets were randomly assigned into 3 groups and treated with a basal diet and 2 m L saline orally(Ctrl group),or the basal diet supplemented with 0.1%EA and 2 m L saline orally(EA group),or the basal diet and 2 m L fecal microbiota suspension from the EA group orally(FEA group),respectively,for 14 d.Compared with the Ctrl group,EA group improved growth performance by increasing average daily feed intake and average daily weight gain(P<0.05)and decreasing fecal scores(P<0.05).EA group also alleviated intestinal damage by increasing the tight junction protein occludin(P<0.05),villus height,and villus height-to-crypt depth ratio(P<0.05),while decreasing intestinal epithelial apoptosis(P<0.05).Additionally,EA group enhanced the jejunum antioxidant capacity by increasing the total antioxidant capacity(P<0.01),catalase(P<0.05),and glutathione/oxidized glutathione(P<0.05),but decreased the oxidative metabolite malondialdehyde(P<0.05)compared to the Ctrl group.Compared with the Ctrl group,EA and FEA groups increased alpha diversity(P<0.05),enriched beneficial bacteria(Ruminococcaceae and Clostridium ramosum),and increased metabolites short-chain fatty acids(P<0.05).Correspondingly,FEA group gained effects comparable to those of EA group on growth performance,intestinal damage,and intestinal antioxidant capacity.In addition,the relative abundance of bacteria shifted in EA and FEA groups was significantly related to the examined indices(P<0.05).Overall,dietary EA supplementation could improve growth performance and attenuate intestinal damage and oxidative stress by regulating the gut microbiota in weanling piglets.Wenxia Qin Baoyang Xu Yuwen Chen Wenbo Yang Yunzheng Xu Juncheng Huang Ting Duo Yihua Mao Guozong Zhou Xianghua Yan Libao Ma 2022Animal Nutrition2022,,4:2
12Expression of sulfur uptake assimilation-related genes in response to cadmium,bensulfuron-methyl and their co-contamination in rice roots显示文摘The responses of sulfur(S) uptake assimilation-related genes' expression in roots of two rice cultivars to cadmium(Cd), bensulfuron-methyl(BSM) and their co-contamination(Cd+BSM) were investigated by gene-chip microarray analysis and quantitative real-time PCR(QRT-PCR) technology. Treatments of Cd and Cd+BSM induced expression of sulfate transporter and permease genes, and promoted sulfate uptake in rice roots. Cd+BSM could alleviate Cd toxicity to cv. Fengmeizhan seedlings, probably due to Cd+BSM promoting greater S absorption by seedlings. Cd and Cd+BSM induced expression of sulfate assimilation-related genes, and thus activated the sulfur assimilation pathway. Cd and Cd+BSM induced expression of phytochelatin synthase and metallothionein genes, and induced expression of glutathione S-transferases(GSTs), glutathione synthase(GS) and antioxidation enzyme genes, which detoxified Cd2+. It is suggested that(to cope with the toxicity of Cd, BSM and their co-contamination) the S uptake and assimilation pathway was activated in rice roots by increased expression of related genes, thus enhancing the supply of organic S for synthesis of Cd or BSM resistance-related substances.Jian Zhou Zegang Wang Zhiwei Huang Chao Lu Zhuo Han Jianfeng Zhang Huimin Jiang Cailin Ge Juncheng Yang 2014Journal of Environmental Sciences2014,26,3:2
13Solubilities of diglycolic acid esters at temperatures ranging from (343 to 363 ) K in supercritical carbon dioxide 显示文摘Wang Wei Yang Haijian Hu Juncheng 2010J Chem Eng Data2010,55,2:1
14Standardization of tritiated water by the CIEMAT/NIST and TDCR methods显示文摘The activity of tritiated water has been standardized by two liquid scintillation counting methods:The CIEMAT/NIST method with the54Mn-standard efficiency tracing and the triple-to-double coincidence ratio(TDCR)method.The samples were prepared with Ultima Gold TM AB liquid scintillation cocktail in low-potassium glass vials.In the application of the CIEMAT/NIST method,the computer program EMILIA was used to calculate the efficiency of3H and54Mn according to the KL1L2L3M atomic rearrangement model.And the detection efficiency of the TDCR counter was calculated using TDCR07 code,which makes it possible to allow for the potential asymmetry between the three photomultiplier tubes.The influence of stopping power and k B factor is discussed in the paper.When a power approach is adopted for the stopping power for electrons below 1ke V and k B is chosen to be 0.0075 cm/Me V,the relative deviation will be only 0.3%between the two methods.WU YongLe LIU HaoRan LIANG JunCheng LIU JiaCheng XIONG WenJun YUE HuiGuo LIU SenLin YANG YuanDi YUAN DaQing 2015Science China(Technological Sciences)2015,58,3:1
