1Slope Stability Analysis Based on Group Decision Theory and Fuzzy Comprehensive Evaluation显示文摘A slope stability evaluation method is proposed combining group decision theory,the analytic hierarchy process and fuzzy comprehensive evaluation.The index weight assignment of each evaluation element is determined by group decision theory and the analytic hierarchy process,and the membership degree of each indicator is determined based on fuzzy set theory.According to the weights and memberships,the membership degrees of the criterion layer are obtained by fuzzy operations to evaluate the slope stability.The results show that(1)the evaluation method comprehensively combines the effects of multiple factors on the slope stability,and the evaluation results are accurate;(2)the evaluation method can fully leverage the experience of the expert group and effectively avoid evaluation errors caused by the subjective bias of a single expert;(3)based on a group decision theory entropy model,this evaluation method can quantitatively evaluate the reliability of expert decisions and effectively improve the efficiency of expert group discussion;and(4)the evaluation method can transform the originally fuzzy and subjective slope stability evaluation into a quantitative evaluation.Peng Xia Xinli Hu Shuangshuang Wu Chunye Ying Chang Liu 2020Journal of Earth Science2020,31,6:11
2Sorption of tetracycline to sediments and soils:assessing the roles of pH,the presence of cadmium and properties of sediments and soils显示文摘Batch sorption experiments were conducted to evaluate the sorption behavior of tetracycline(TC,H_(3)L)on sediments and soils in the presence and absence of cadmium(Cd),as affected by pH and properties of sediments and soils.The results indicated stronger nonlinearity and higher capacity of TC sorption on sediments than on soils.Sorption of TC also strongly depended on environmental factors and sediment/soil properties.Lower pH facilitated TC sorption through a cation exchange mechanism,which also took place at pH values above 5.5,where TC existed as a zwitterion(H_(2)L^(0))or anions(HL^(-)and L^(2-)).When pH was above 7,however,ligand-promoted dissolution of TC might occur due to TC weakening the Al-O bond of aluminum oxide and the Fe-O bond of iron oxide.Natural organic matter(NOM)plays a more important role in TC sorption than cation exchange capacity(CEC)and clay contents.The presence of Cd(II)increased TC sorption on both sediments and soils,which resulted from the decrease of equilibrium solution pH caused by Cd^(2+)exchange with H^(+)ions of sediment/soil surfaces.The increase of TC sorption was also related to the formation of TC-Cd complexes,where Cd^(2+)acted as a bridge between the sediment/soil and TC.Guixiang ZHANG Xitao LIU Ke SUN Ye ZHAO Chunye LIN 2010Frontiers of Environmental Science & Engineering2010,4,4:5
3Peroxymonosulfate assisted mechanochemical method for the degradation of phenanthrene in contaminated soils显示文摘In recent years,mechanochemical method has received attention in the field of degrading pollutants,especially for persistent organic pollutants.In this study,peroxymonosulfate(PMS)as a co-grinding reagent,coupled with contaminated soil were placed in a ball mill for mechanochemical reaction.Through investigating the influences of ball-milling parameters on the degradation efficiency,the reaction conditions were optimized.Under the optimal condition(mass ratio of soil to oxidant is 10:1,mass ratio of ball to material is 30:1,rotation speed of ball mill is 400 rpm),more than 98%phenanthrene(PHE)in contaminated soil could be degraded within 4 h.Meanwhile,the effects of soil organic matter content and soil type on the degradation efficiency were investigated.The results showed that the organic matter content was negatively correlated with the degradation efficiency.XPS analysis provided evidence for the breakage of the CeC bond and confirmed that Fe in soil was an important factor in activating PMS.XRD further verified the destruction of PHE structure.GC-MS analysis was performed to identify the intermediates and possible pathways were proposed.Guoxuan Fan Xitao Liu Chunye Lin Peizhong Li 2018Emerging Contaminants2018,4,1:4
4SARS-CoV-2 Omicron RBD shows weaker binding affinity than the currently dominant Delta variant to human ACE2显示文摘Dear Editor,SARS-coronavirus-2(SARS-CoV-2)Omicron variant(B.1.1.529)is of great concern to the world due to its multiple mutations that may have an impact on transmissibility and immune evasion.1 Compared to the wild type(WT),Omicron carries as many as 30 single point mutations,3 deletion mutation and one insertion mutation on its spike protein.Strikingly,there are 15 mutations observed in the Omicron receptor-binding domain(RBD),10 of which are in the receptor-binding motif(RBM)that human angiotensin-converting enzyme 2(ACE2)and most monoclonal antibodies(mAbs)interact directly with.As a comparison,the currently dominant variant Delta(B.1.617.2)has only 2 mutations(L452R and T478K)in its RBM and additional K417N and E484K mutations sometimes.Therefore,Omicron variant may significantly impact the binding affinity to ACE2 and effectiveness of currently available mAbs.Consequently,Omicron mutant has aroused wide concern,many countries have taken measures on entry restrictions to prevent its rapid spread.However,the transmissibility and immune evasion risk of Omicron have not been properly evaluated.Leyun Wu Liping Zhou Mengxia Mo Tingting Liu Chengkun Wu Chunye Gong Kai Lu Likun Gong Weiliang Zhu Zhijian Xu 2022Signal Transduction and Targeted Therapy2022,7,2:2
5Protein C receptor is a therapeutic stem cell target in a distinct group of breast cancers显示文摘Breast cancer is a heterogeneous disease.In particular,triple-negative breast cancer(TNBC)comprises various molecular subgroups with unclear identities and currently has few targeted treatment options.Our previous study identified protein C receptor(Procr)as a surface marker on mammary stem cells(MaSCs)located in the basal layer of the normal mammary gland.Given the possible connection of TNBC with basal layer stem cells,we conducted comparative analyses of Procr in breast cancers of mouse and human origin.In mouse mammary tumors,we showed that Procr+cells are enriched for cancer stem cells(CSCs)in Wnt1 basal-like tumors,but not in Brea basal-like tumors or PyVT luminal tumors.In human cancers,PROCR was robustly expressed in half of TNBC cases.Experiments with patient-derived xenografts(PDXs)revealed that PROCR marks CSCs in this discrete subgroup(referred to as PROCR+TNBC).Interfering with the function of PROCR using an inhibitory nanobody reduced the CSC numbers,arrested tumor growth and prevented rapid tumor recurrence.Our data suggest a key role of MaSC in breast tumorigenesis.Moreover,our work indicates that PROCR can be used as a biomarker to stratify TNBC into clinically relevant subgroups and may provide a novel targeted treatment strategy for this clinically important tumor subtype.Daisong Wang Xin Hu Chunye Liu Yingying Jia Yiqin Bai Cheguo Cai Jingqiang Wang Lanyue Bai Ruikai Yang ChangDong Lin Yi-Rong Liu Shan Li Feng Qiao Ling Yao Li Chen Gaoxiang Ge Hai Jiang Dianfan Li Lin Li JianFeng Chen Zhi-Ming Shao Yi Arial Zeng 2019Cell Research2019,29,10:2

7Optical-pulse-coding phase-sensitive OTDR with mismatched filtering显示文摘Optical-pulse-coding(OPC)phase-sensitive optical time-domain reflectometry(Φ-OTDR)sends a train of pulses into a fiber,and has high spatial resolution decided by the duration of a subpulse while achieving signal-to-noise ratio(SNR)enhancement.OPCΦ-OTDR with a shorter measurement time is favorable.However,the scan rate,which is the reciprocal of the measurement time,is not easy to optimize.In this paper,mismatched filtering is introduced into OPCΦ-OTDR for the first time,which can reach the theoretical limit of scan rate determined by the fiber length.Also,the initial phase of each subpulse can be set arbitrarily,showing the capacity for controlling the location of interference fading.Although the design of the mismatched filter is based on the least-squares criterion,satisfactory decoding results are obtained,indicating that more advanced mismatched filter designs are worthy of further investigation to achieve higher performance.Yongxin LIANG Zinan WANG Shengtao LIN Yuyao WANG Jialin JIANG Zijie QIU Chunye LIU Yunjiang RAO 2022Science China(Information Sciences)2022,65,9:1

17Transfer learning for deep neural network-based partial differential equations solving显示文摘Deep neural networks(DNNs)have recently shown great potential in solving partial differential equations(PDEs).The success of neural network-based surrogate models is attributed to their ability to learn a rich set of solution-related features.However,learning DNNs usually involves tedious training iterations to converge and requires a very large number of training data,which hinders the application of these models to complex physical contexts.To address this problem,we propose to apply the transfer learning approach to DNN-based PDE solving tasks.In our work,we create pairs of transfer experiments on Helmholtz and Navier-Stokes equations by constructing subtasks with different source terms and Reynolds numbers.We also conduct a series of experiments to investigate the degree of generality of the features between different equations.Our results demonstrate that despite differences in underlying PDE systems,the transfer methodology can lead to a significant improvement in the accuracy of the predicted solutions and achieve a maximum performance boost of 97.3%on widely used surrogate models.Xinhai Chen Chunye Gong Qian Wan Liang Deng Yunbo Wan Yang Liu Bo Chen Jie Liu 2021Advances in Aerodynamics2021,3,1:1

19Response of soil microbial activities and ammonia oxidation potential to environmental factors in a typical antimony mining area显示文摘Mining,smelting and tailing deposition activities can cause metal(loid)contamination in surrounding soils,threatening ecosystems and human health.Microbial indicators are sensitive to environmental factors and have a crucial role in soil ecological risk assessment.Xikuangshan,the largest active antimony(Sb)mine in the world,was taken as the research area.The soil properties,metal(loid)contents and microbial characteristics were investigated and their internal response relationships were explored by multivariate statistical analysis.The assessment of the single pollution index and Nemerow synthetic pollution index(PN)showed that the soils were mainly polluted by Sb,followed by Cd and As,in which sampling site S1 had a slight metal(loid)pollution and the other sampling sites suffered from severe synthetic metal(loid)pollution.The microbial characteristics were dissimilar among sampling points at different locations from the mining area according to hierarchical cluster analysis.The correlation analysis indicated that fluorescein diacetate hydrolase,acid phosphatase,soil basal respiration andmicrobial biomass carbonwere negatively correlatedwith PN,indicating their sensitivity to combined metal(loid)contamination;that dehydrogenase was positively correlated with pH;and that urease,potential ammonia oxidation and abundance of ammonia-oxidizing bacteria and archaea were correlated with N(nitrogen)contents.However,β-glucosidase activity had no significant correlations with physicochemical properties and metal(loid)contents.Principal components analysis suggested bioavailable Sb and pH were the dominant factors of soil environment in Xikuangshan Sb mining area.Our results can provide a theoretical basis for ecological risk assessment of contaminated soil.Aihua Wang Shujun Liu Jun Xie Wei Ouyang Mengchang He Chunye Lin Xitao Liu 2023Journal of Environmental Sciences2023,,5:0
20Comparison of antimony and arsenic behaviour at the river-lake junction in the middle of the Yangtze River Basin显示文摘As typical metalloid toxic elements widely distributed in environmental media,the geochemical behaviour of antimony(Sb)and arsenic(As)affects environmental safety.We selected the surface waters and sediments at the river-lake junction of Dongting Lake as the research objects,analysed the concentration and chemical partitioning of Sb and As,assessed its contamination and ecological risk levels,and discussed its sources and potential influencing factors.The concentrations of dissolved Sb and As in surface waters were low(<5.46μg/L),and the concentrations of Sb and As in surface sediments were 2.49-22.65mg/kg and 11.10-136.34 mg/kg,respectively.Antimony and As in sediments were mainly enriched in the fraction of residues,but the proportion of As in bioavailability was significantly higher than that of Sb.Although the contamination level of Sb was higher than that of As,the risk assessment code(RAC)showed that the ecological risk level of As was higher than that of Sb.Rainwater erosion and mining activities(in the midstream of Zijiang River)were the main contaminated sources of Sb,while As was affect mainly by rainwater erosion.The contamination and ecological risk of Sb in the inlet of the Zijiang River should receive considerable attention,while those of As in the inlet of the Xiangjiang River should also be seriously considered.This study highlights the need for multi-index-based assessments of contamination and ecological risk and the importance of further studies on the environmental behaviour of metalloids in specific hydrological conditions,such as river-lake junctions.Huiji Liu Wei Zeng Ziyang Lai Mengchang He Chunye Lin Wei Ouyang Xitao Liu 2024Journal of Environmental Sciences2024,,2:0
