| 1 | Tectonic Evolution of the Meso-Tethys in the Western Segment of Bangonghu-Nujiang Suture Zone: Insights from Geochemistry and Geochronology of the Lagkor Tso Ophiolite显示文摘The subduction of the Bangonghu-Nujiang Meso-Tethys and the collision between the Lhasa and Qiangtang blocks were important events in the growth of the Tibetan crust. However,the timing of collision initiation and closure timing,as well as nature and structure of the Bangonghu ocean basin,are still poorly constrained. The Lagkor Tso ophiolite,located in the south of Gerze County,Tibet,is one of the most completed ophiolites preserved in the southern side of the BangonghuNujiang suture zone. This study discussed the tectonic evolution of the Bangonghu-Nujiang suture zone as revealed by the Lagkor Tso ophiolite investigated by field investigations,petrology,geochemistry,geochronology and tectonic analysis methods. We present new LA-ICP-MS zircon U-Pb and 39Ar/40 Ar ages for the Lagkor Tso ophiolite,in addition to geochemical and platinum-group element(PGE) data presented for the Lagkor Tso ophiolite in Tibet. It is suggested that the ancient Lagkor Tso oceanic basin split in Middle Jurassic(161.2 ± 2.7 Ma – 165.4 ± 3.5 Ma),and experienced a second tectonic emplacement during the Early Cretaceous(137.90 ± 6.39 Ma). The Lagkor Tso ophiolite likely developed in an independent suture zone. The Bangonghu-Nujiang ocean subducted southwards,and the dehydration of the subducting oceanic crust materials caused partial melting of the continental mantle wedge,which formed the second-order expanding center of the obduction dish. This led to inter-arc expansion,followed by the formation of inter-arc and back-arc basins with island arc features,which are represented by ophiolites around the Shiquanhe-Lagkor Tso-Yongzhu region. The tectonic environment presently can be considered to be similar to that of the current Western Pacific,in which a large number of island arc-ocean basin systems are developed. | YUAN Yajuan YIN Zhengxin LIU Weiliang HUANG Qiangtai LI Jianfeng LIU Hongfei WAN Zhifeng CAI Zhourong XIA Bin | 2015 | Acta Geologica Sinica(English Edition)2015，89，2： | 17 |
| 2 | Marginal optimization method to improve the inconsistent comparison matrix in the analytic hierarchy process显示文摘To improve the inconsistency in the analytic hierarchy process(AHP), a new method based on marginal optimization theory is proposed. During the improving process, this paper regards the reduction of consistency ratio(CR) as benefit, and the maximum modification compared to the original pairwise comparison matrix(PCM) as cost, then the improvement of consistency is transformed to a benefit/cost analysis problem. According to the maximal marginal effect principle, the elements of PCM are modified by a fixed increment(or decrement) step by step till the consistency ratio becomes acceptable, which can ensure minimum adjustment to the original PCM so that the decision makers' judgment is preserved as much as possible. The correctness of the proposed method is proved mathematically by theorem. Firstly, the marginal benefit/cost ratio is calculated for each single element of the PCM when it has been modified by a fixed increment(or decrement).Then, modification to the element with the maximum marginal benefit/cost ratio is accepted. Next, the marginal benefit/cost ratio is calculated again upon the revised matrix, and followed by choosing the modification to the element with the maximum marginal benefit/cost ratio. The process of calculating marginal effect and choosing the best modified element is repeated for each revised matrix till acceptable consistency is reached, i.e., CR<0.1. Finally,illustrative examples show the proposed method is more effective and better in preserving the original comparison information than existing methods. | Shihui Wu Jiang Xie Xiaodong Liu Bo He Minxiang Yang Zhengxin Li | 2017 | Journal of Systems Engineering and Electronics2017，28，6： | 11 |
| 3 | Severity of early allograft dysfunction following donation after circulatory death liver transplantation:a multicentre study显示文摘Background:Early allograft dysfunction(EAD)is associated with decreased graft and patient survival rates.This study aimed to identify the severity of EAD and develop a predictive model for EAD after donation after circulatory death(DCD)liver transplantation(LT).Furthermore,the influence of operative time on EAD incidence was also evaluated.Methods:In this retrospective,multicentre cohort study,nomograms were established based on a single-centre training cohort(n=321)and validated in a 3-center validation cohort(n=501).Results:The incidence rate of EAD was 46.4%(149/321)in the training cohort and 40.5%(203/501)in the validation cohort.Of the 149 EAD patients in the training cohort,77 patients with either elevated alanine aminotransferase(ALT)or aspartate aminotransferase(AST)were classified as having EAD type A,and the rest of the EAD patients were classified as having EAD type B.Recipients with EAD type B had lower graft and patient survival rates than recipients with EAD type A(P=0.043 and 0.044,respectively).We further developed a nomogram to predict EAD(graft weight,cold ischemia time,donor age,model for end-stage liver disease(MELD)score)and another nomogram to predict EAD type B(graft weight,cold ischemia time,MELD score).The nomograms for the prediction of EAD and EAD type B had good discrimination[concordance index(C-index)=0.712(0.666-0.758),0.707(0.641-0.773)]and calibration[Hosmer-Lemeshow(HL)P=0.384,P=0.425]in the validation cohort.An increased operative time(>6 h)was associated with increased EAD and EAD type B incidence in the high-risk group(P=0.005,P=0.020,respectively).Conclusions:EAD type B was associated with decreased graft and patient survival rates.The novel nomograms effectively predicted the incidence of EAD and EAD type B in DCD LT patients. | Kun Wang Di Lu Yuhui Liu Wangyao Li Li Zhuang Zhenyu Ma Qinfen Xie Binhua Pan Yichao Wu Junli Chen Lidan Lin Xiaowen Feng Qiang Wei Xuyong Wei Haiyang Xie Zhengxin Wang Shusen Zheng Xiao Xu | 2021 | Hepatobiliary Surgery and Nutrition2021，10，1： | 4 |
| 4 | Functions and clinical significance of mechanical tumor microenvironment:cancer cell sensing,mechanobiology and metastasis显示文摘Dynamic and heterogeneous interaction between tumor cells and the surrounding microenvironment fuels the occurrence,progression,invasion,and metastasis of solid tumors.In this process,the tumormicroenvironment(TME)fractures cellular and matrix architecture normality through biochemical and mechanical means,abetting tumorigenesis and treatment resistance.Tumor cells sense and respond to the strength,direction,and duration of mechanical cues in the TME by various mechanotransduction pathways.However,far less understood is the comprehensive perspective of the functions and mechanisms of mechanotransduction.Due to the great therapeutic difficulties brought by the mechanical changes in the TME,emerging studies have focused on targeting the adverse mechanical factors in the TME to attenuate disease rather than conventionally targeting tumor cells themselves,which has been proven to be a potential therapeutic approach.In this review,we discussed the origins and roles ofmechanical factors in the TME,cell sensing,mechano-biological coupling and signal transduction,in vitro construction of the tumormechanicalmicroenvironment,applications and clinical significance in the TME. | Hanying Zhou Meng Wang Yixi Zhang Qingqing Su Zhengxin Xie Xiangyan Chen Ran Yan Ping Li Tingting Li Xiang Qin Hong Yang ChunhuiWu Fengming You Shun Li Yiyao Liu | 2022 | Cancer Communications2022，42，5： | 3 |

| 6 | A consistency improving method in the analytic hierarchy process based on directed circuit analysis显示文摘Test of consistency is critical for the analytic hierarchy process(AHP) methodology. When a pairwise comparison matrix(PCM) fails the consistency test, the decision maker(DM) needs to make revisions. The state of the art focuses on changing a single entry or creating a new matrix based on the original inconsistent matrix so that the modified matrix can satisfy the consistency requirement. However, we have noticed that the reason that causes inconsistency is not only numerical inconsistency, but also logical inconsistency, which may play a more important role in the whole inconsistency. Therefore, to realize satisfactory consistency, first of all, we should change some entries that form a directed circuit to make the matrix logically consistent, and then adjust other entries within acceptable deviations to make the matrix numerically consistent while preserving most of the original comparison information. In this paper, we firstly present some definitions and theories, based on which two effective methods are provided to identify directed circuits. Four optimization models are proposed to adjust the original inconsistent matrix. Finally, illustrative examples and comparison studies show the effectiveness and feasibility of our method. | WU Shihui LIU Xiaodong LI Zhengxin ZHOU Yu | 2019 | Journal of Systems Engineering and Electronics2019，30，6： | 2 |
| 7 | Construction of ZnIn_(2)S_(4)-CdIn_(2)S_(4) Microspheres for Efficient Photo-catalytic Reduction of CO_(2) with Visible Light显示文摘ZnIn_(2)S_(4) has emerged in water splitting and degradation of dyes due to its good stability and light absorption properties.However,there are still few reports of CO_(2) photoreduction.Herein,we successfully synthesized ZnIn_(2)S_(4) and obtained a series of ZnIn_(2)S_(4)-CdIn_(2)S_(4) heterostructured microspheres through the ion exchange method,and first used them in photocatalytic CO_(2) reduction in noble-metal-free systems.The activity results showed that these ZnIn_(2)S_(4)-CdIn_(2)S_(4) photocatalysts exhibit excellent catalytic activity under visible light,and the best CO yield is as high as 33.57μmol・h^(-1) with a selectivity of 91%.Furthermore,the stability and reusability of ZnIn_(2)S_(4)-CdIn_(2)S_(4) was firmly confirmed by diverse characterizations,including X-ray diffraction(XRD),scanning electron microscopy(SEM),transmission electron microscopy(TEM),X-ray photoelectron spectroscopy(XPS),energy-dispersive X-ray spectroscopy(EDX)and N2 adsorption measurements. | Shitong Han Bifang Li Lijuan Huang Hailing Xi Zhengxin Ding Jinlin Long | 2022 | Chinese Journal of Structural Chemistry2022，41，1： | 2 |
| 8 | Quantitative identification and the evolution characteristics of production–living–ecological space in the mountainous area:From the perspective of multifunctional land显示文摘Developed here is an integrated framework for identifying production–living–ecological space(PLES)quantitatively at grid scale from the perspective of multifunction land use,and 25 compound space types are classified to highlight the multiple functions of PLES.As a typical mountainous city in northern Hebei province,Zhangjiakou is used as a case study,and the results show that more than 80%of the land space in Zhangjiakou has remarkable triple functionality.The living-dominated space and the production-dominated space are distributed mainly in the valleys of the Yanghe,Sanggan,and Huliu rivers and have obvious spatial consistency,while the ecological-dominated space is concentrated mostly at the eastern Yanshan Mountains and southern Taihang Mountains and complements the other two types of space.The former two are spatially fragmented,while the latter has been expanding to the periphery over time.From 1990 to 2015,the ecological-dominated space has increased the most by 1555.02 km^(2),while the living-dominated space has increased the least by 816.79 km^(2).The types of PLES are more diverse in the medium and low mountains and the areas with gentle slope,and the influencing factors include natural ecological environment,socioeconomic development,human consumption demand,and institutional policies.Therefore,these findings can mitigate conflicts among PLES in mountainous and similar areas,and promote the balanced development of land space. | JI Zhengxin LIU Chao XU Yueqing SUN Minxuan WEI Hejie SUN Danfeng LI Yaoyao ZHANG Ping SUN Qiangqiang | 2023 | Journal of Geographical Sciences2023，33，4： | 1 |

| 12 | Effects of Dietary Protein and Lipid Levels on Growth Performance, Muscle Composition, Immunity Index and Biochemical Index of the Greenfin Horse-Faced Filefish (Thamnaconus septentrionalis) Juvenile显示文摘The effects of different dietary protein and lipid levels on juvenile greenfin horse-faced filefish(Thamnaconus septentrionalis)was experimentally evaluated in a 56-day study.Fish(initial weight 6.47±0.56 g)were fed with nine different diet combinations containing three varying levels of protein(37%,43%,49%)and lipids(4%,7%,10%)in triplicates,where the protein-to-energy(P/E)ratios of the diets varied in the range of 19.17-26.99mgkJ−1.Results showed that fish fed diets containing 49%protein and 10%lipid exhibited significantly lower feed intake than those fed other diets.The weight gain of fish fed diets with 43%protein was significantly higher than that of fish fed 37%or 49%protein diets.While no significant change in weight gain was observed when lipid content was increased from 4%to 7%,weight gain decreased significantly when lipid increased from 7%to 10%.The protein efficiency ratio and feed efficiency were highest when the fish were fed the diet with 49%protein and 7%lipids.Muscle crude lipid content was positively correlated with dietary protein level regardless of lipid level.The diet of 43%protein or 7%lipids significantly reduced the activity of alanine aminotransferase and aspartate aminotransferase in liver.The contents of aspartate aminotransferase,superoxide dismutase and malondialdehyde were significantly increased from 4%to 10%lipids in plasma.The plasma total cholesterol and triglyceride contents were positively correlated with dietary lipid level at the same protein level.Our comprehensive analysis concluded that a diet with 43%protein and 7%lipid,with a P/E ratio of 23.07mgkJ−1,significantly promote the growth performance,feed utilization and health of juvenile greenfin horse-faced filefish. | XU Zhengxin ZHANG Pengfei CHANG Qing CHEN Siqing BIAN Li WANG Zhida | 2021 | Journal of Ocean University of China2021，20，5： | 1 |

| 19 | Cross-linked hole transport layers for high-efficiency perovskite tandem solar cells显示文摘Perovskite tandem solar cells have recently received extensive attention due to their promise of achieving power conversion efficiency(PCE)beyond the limits of single-junction cells.However,their performance is still largely constrained by the widebandgap perovskite solar cells which show considerable open-circuit voltage(VOC)losses.Here,we increase the VOCand PCE of wide-bandgap perovskite solar cells by changing the hole transport layer(HTL)from commonly used poly(bis(4-phenyl)(2,4,6-trimethylphenyl)amine)(PTAA)to in-situ cross-linked small molecule N_(4),N_(4)′-di(naphthalen-1-yl)-N_(4),N_(4)′-bis(4-vinylphenyl)biphenyl-4,4′-diamine(VNPB).The stronger interaction and lower trap density at the VNPB/perovskite interface improve the PCE and stability of wide-bandgap perovskite solar cells.By using the cross-linked HTL for front wide-bandgap subcells,PCEs of 24.9%and 25.4%have been achieved in perovskite/perovskite and perovskite/silicon tandem solar cells,respectively.The results demonstrate that cross-linkable small molecules are promising for high-efficiency and cost-effective perovskite tandem photovoltaic devices. | Yurui Wang Shuai Gu Guoliang Liu Liping Zhang Zhou Liu Renxing Lin Ke Xiao Xin Luo Jianhua Shi Junling Du Fanying Meng Ludong Li Zhengxin Liu Hairen Tan | 2021 | Science China Chemistry2021，64，11： | 1 |
| 20 | The Welfare Effects of Carbon Tax on Chinese Households: A Study Based on the 2013 Chip Survey Data显示文摘Based on the micro-data from the 2013 Chinese Household Income Project(CHIP) Survey, the authors use a Quadratic Almost Ideal Demand System(QUAIDS) model to simulate and measure the impacts on the welfare of urban and rural households with different incomes after a carbon tax at 50 RMB/ton was levied in China. The results show that the collection of carbon tax will increase households’ consumer spending to varying degrees. In urban areas, the carbon tax exerts the greatest impact on low-income households, followed by high-income households;while in rural areas, it has the most significant effects on high-income households and the least on lowincome households. On the whole, carbon tax’s impact on urban households is greater than that on rural households. To a certain extent, it can help the household income inequality change for the better and narrow the urban–rural income gap. Since the carbon tax does not act on the distribution of Chinese household income in a simply regressive or progressive way, the authors believe that China should implement supporting policies such as tax subsidies or tax refund as supplements to carbon taxation in an effort to establish a mechanism for cyclic utilization of carbon tax revenue. | LI Xuehui LI Zhi WANG Zhengxin | 2020 | Chinese Journal of Urban and Environmental Studies2020，8，4： | 0 |
