| 1 | Response of Vegetation in the Qinghai-Tibet Plateau to Global Warming显示文摘Using satellite-observed Normalized Difference Vegetation Index (NDVI) dada and station-observed surface air temperature anomalies for the Northern Hemisphere (NH), we analyze the spatio-temporal characteristics of vege- tation variations in the Qinghai-Tibet Plateau and their correlations with global warming from 1982 to 2002. It is found that the late spring and early summer (May-June) are the months with the strongest responses of vegetation to global warming. Based on the Rotated Empirical Orthogonal Function (REOF) method, the study shows that the first REOF spatial pattern of average NDVI for May-June reveals the northern and southern zones with great inter-annual variations of vegetation, the northern zone from the eastern Kunlun Mountains to the southwestern Qilian Mountain and southern zone from the northern edge of the Himalayas eastward to the Hengduan Mountains. The vegetation, especially grassland, in the two zones increases significantly with global warming, with a correlation coefficient of 0.71 between the first REOF of May-June vegetation and the April-May surface air temperature anomaly in the NH during 1982-2002. A long-term increasing trend in May-June vegetation for the plateau region as a whole is also attributed mainly to global warming although there are considerable regional differences. The areas with low NDVI (grassland and shrubland) usually respond more evidently to global warming, especially since the 1990s, than those with moderate or high NDVI values. | XU Weixin LIU Xiaodong | 2007 | Chinese Geographical Science2007，17，2： | 27 |

| 4 | Genetic alteration and mutation profiling of circulating cell-free tumor DNA(cfDNA) for diagnosis and targeted therapy of gastrointestinal stromal tumors显示文摘Gastrointestinal stromal tumors(GISTs) have been recognized as a biologically distinctive type of tumor,different from smooth muscle and neural tumors of the gastrointestinal tract.The identification of genetic aberrations in proto-oncogenes that drive the growth of GISTs is critical for improving the efficacy of cancer therapy by matching targeted drugs to specific mutations.Research into the oncogenic mechanisms of GISTs has found that these tumors frequently contain activating gene mutations in either platelet-derived growth factor receptor A(PDGFRA) or a receptor tyrosine protein associated with a mast cell growth factor receptor encoded by the KIT gene.Mutant cancer subpopulations have the potential to disrupt durable patient responses to molecularly targeted therapy for GISTs,yet the prevalence and size of subpopulations remain largely unexplored.Detection of the cancer subpopulations that harbor low-frequency mutant alleles of target proto-oncogenes through the use of molecular genetic methods,such as polymerase chain reaction(PCR) target amplification technology,is hampered by the high abundance of wildtype alleles,which limit the sensitivity of detection of these minor mutant alleles.This is especially true in the case of mutant tumor DNA derived 'driver' and 'drug-resistant' alleles that are present in the circulating cell-free tumor DNA(cfDNA) in the peripheral blood circulation of GIST patients.So-called 'liquid biopsy' allows for the dynamic monitoring of the patients' tumor status during treatment using minimally invasive sampling.New methodologies,such as a technology that employs a xenonucleic acid(XNA) clamping probe to block the PCR amplification of wild-type templates,have allowed improved molecular detection of these low-frequency alleles both in tissue biopsy samples and in cfDNA.These new methodologies could be widely applied for minimally invasive molecular testing in the therapeutic management of GISTs. | Weixin Yan Aiguo Zhang Michael J.Powell | 2016 | Chinese Journal of Cancer2016，35，7： | 13 |
| 5 | Natural^(15)N abundance in soils and plants in relation to N cycling in a rangeland in Inner Mongolia显示文摘Aims Natural 15N abundance provides integrated information about nitrogen(N)input,transformation and output,indirectly reflecting N cycling traits within terrestrial ecosystems.However,relationships between natural 15N abundance and N cycling processes are poorly understood in China.Here,our primary objectives were to(i)examine the effects of grazing at varying levels of intensity on d15N of soils and plants in a semi-arid grassland;(ii)detect the relationships between d15N of soils and four major N cycling processes(i.e.mineralization,nitrification,denitrification and ammonia volatilization);and(iii)determine whether d15N of soils can be used as an indicator of N cycling in this semi-arid grassland.Methods The field experiment was conducted within the long-term(17-year)grazing enclosures in a semi-arid grassland in Inner Mongolia.Five grazing intensities(0.00,1.33,2.67,4.00 and 5.33 sheep ha1)were designed.d15N values of topsoils(0–10 cm),surface soils(0–2 cm)and plants were measured in 2006.Differences in d15N of soils and plants between the five grazing intensities were examined.Rates of four soil N cycling processes were measured periodically during the 2005 and 2006 growing seasons.The d15N values of topsoils were linked to the four N cycling processes to investigate their relationships.Important Findings The d15N values of topsoils(5.20–5.96&)were substantially higher than the d15N values of plants(2.51–2.93&)and surface soils(1.44–2.92&)regardless of grazing intensities.The 15N-depleted N losses during microbial decomposition of organic matter in concert with the downward movement of residual substrate over time are the possible causes of higher d15N values in topsoils than in surface soils.In addition,the d15N values of topsoils were positively correlated with the d15N values of both plants and surface soils.Grazing,especially the high-intensity grazing(5.33 sheep ha1),resulted in a significant decrease in d15N of surface soils.However,no statistically significant variations in d15N of topsoils and plants were found in response to grazing.The d15N values of topsoils exhibited significant dependence on the cumulative rates of NH3 volatilization,net nitrification and denitrification in 2005 but not in 2006. | Yuqing Xu Jicheng He Weixin Cheng Xuerong Xing Linghao Li | 2010 | Journal of Plant Ecology2010，3，3： | 12 |

| 7 | Simulating Mechanism of Interaction Between Ports and Cities Based on System Dynamics: A Case of Dalian, China显示文摘Port-city system is a complex and integral system, and it can be simulated by system dynamic method, which is used to be employed to solve nonlinear problems. Based on the causality of the every element in the port-city system, the authors analyzed the feedback relation and logical relation among the system variables and system structure. A system-dynamic flow chart and correlation equations were put forward with VENSIM software, the quantitative relation was described, and the model was debugged. The development trend of the main influence factors in port-city system was simulated. By changing the parameters values of variables in the model, we studied the influence degree of each related factor. It is found that: 1) Foreign trade throughput of port play an important role in the development of export-oriented economy. 2) The development of primary industry and secondary industry affects most of the water transportation demand. With the constant increase of tertiary industry proportion in the industrial structure, the demand of national economy for water transportation decreases gradually. 3) Water transportation presents a kind of oversupply development situation, so port construction should properly slow down. 4) With the development of ports, its direct and indirect contribution to urban economy has been continuously increasing, but contribution rate will be continuously decreasing. | LUAN Weixin CHEN Hang WANG Yuewei | 2010 | Chinese Geographical Science2010，20，5： | 8 |

| 9 | Meteor radar observation of circulation near mesopause over Wuhan显示文摘The Wuhan meteor radar is the first all-sky meteor radar in China. The circulation near the mesopause from February to September 2002 is studied based on the data obtained by the Wuhan meteor radar. The zonal wind is usually eastward in winter from 80 to 100 km. The mean zonal wind become westward from March to early of May, when the winter circulation reverses to the summer circulation. But at the meteor heights, the zonal circulation usually becomes eastward after the middle of May. The meridional circulation is always equatorward. The peaks of the meridional wind move downward with the height, and the peak value reaches its maximum of 21 ms-1 in July. Having made a comparison between monthly mean wind and HWM93 model wind, the value of southward wind, the maximal value of eastward wind as well as the reversal height of zonal wind are found to be quite different from each other. | XIONG Jiangang, WAN Weixin, NING Baiqi & LIU Libo Wuhan Institute of Physics and Mathematics, Chinese Academy of Sciences, Wuhan 430071, China Correspondence should be addressed to Xiong Jiangang (e-mail: xjg@wipm.ac.cn) | 2003 | Chinese Science Bulletin2003，48，15： | 8 |

| 11 | The interaction of CpEBF1 with CpMADSs is involved in cell wall degradation during papaya fruit ripening显示文摘Ethylene plays a pivotal role in climacteric fruit ripening;whereas 1-MCP,a non-toxic antagonist of ethylene,prevents ethylene-dependent responses and fruit ripening.In this study,a short-term treatment(1 h)with 400 nL L^(−1)1-MCP delayed the ripening of harvested papaya.However,long-term application of 1-MCP(400 nL L^(−1),16 h)resulted in abnormal fruit ripening,with the fruits exhibiting normal yellowing without softening,significantly higher cellulose and lignin contents,and intact cell walls(CW).Furthermore,we found that long-term treatment with 1-MCP significantly inhibited the expression of CpEBF1,an EIN3-binding F-box-1 gene.A protein interaction analysis using yeast two-hybrid,BiFC and GST pull-down assays showed that CpEBF1 interacts with the CpMADS1/3 and CpEIL1 proteins.The interaction of CpEBF1 with CpMADS1/3 further activated the activities of CW-degradation gene promoters.Subcellular localization showed that these proteins were localized in the nucleus.Additionally,the expression levels of CpMADS1/3,CpEIL1,and several CW-degradation-related genes were significantly downregulated by long-term 1-MCP treatment.Therefore,we propose that the inhibited expression of CpEBF1 and CpMADS1/3 resulted in the repressed activation of CW-degradation-related genes via their interaction,thereby resulting in fruit softening disorders. | Xiaochun Ding Xiaoyang Zhu Lanlan Ye Shuangling Xiao Zhenxian Wu Weixin Chen Xueping Li | 2019 | Horticulture Research2019，6，1： | 7 |
| 12 | Efficient Attribute-Based Encryption from R-LWE显示文摘Attribute-based encryption(ABE) has been an active research area in cryptography due to its attractive applications. But almost all attribute-based encryption schemes are based on bilinear maps, which leave them vulnerable to quantum cryptanalysis. The latticebased ABE schemes from the Learning with errors(LWE)have appeared, but they are not efficient enough for practical applications. Thus we propose an efficient attributebased encryption based on the Learning with errors over Rings(R-LWE), which is called ABE R-LWE. The security analysis shows that ABE R-LWE scheme is secure in the selective-set model under the R-LWE assumption, whose security can reduce to the hardness of the shortest vector problem in the worst case on ideal lattices. The efficiency analysis indicates that ABE R-LWE is more efficient than previous ABE cryptosystems on lattices. | ZHU Weiling YU Jianping WANG Ting ZHANG Peng XIE Weixin | 2014 | Chinese Journal of Electronics2014，23，4： | 6 |

| 14 | Variation effect of strain rate on microstructure in isothermal compression of Ti-6Al-4V alloy显示文摘Isothermal compression of the Ti-6Al-4V alloy at the deformation temperatures of 950 and 980℃,height reductions of 30% and 60%,and strain rates of 0.001,0.010,0.100 and 1.000 s-1 was conducted,wherein the variations of microstructure with strain rate were investigated.The experimental results showed that the variation of the microstructure with the strain rate under one condition was significantly different from that under another condition,which meaned that the interaction between the processing parameters was great.The optimization of the strain rate under one condition was not suitable for another condition.Therefore,selecting the forging equipment and optimizing the strain rate should be based on simultaneously considering the deformation temperature and height reduction. | Yu, Weixin Li, Miaoquan Luo, Jiao | 2012 | Rare Metals2012，31，1： | 6 |
| 15 | A chemo-mechanical model coupled with thermal effect on the hollow core–shell electrodes in lithium-ion batteries显示文摘Electrode is a key component to remain durability and safety of lithium-ion(Li-ion) batteries. Li-ion insertion/removal and thermal expansion mismatch may induce high stress in electrode during charging and discharging processes. In this paper, we present a continuum model based on COMSOL Multiphysics software, which involves thermal, chemical and mechanical behaviors of electrodes. The results show that,because of diffusion-induced stress and thermal mismatch, the electrode geometry plays an important role in diffusion kinetics of Li-ions. A higher local compressive stress results in a lower Li-ion concentration and thus a lower capacity when a particle is embedded another, which is in agreement with experimental observations. | Bin Hu Zengsheng Ma Weixin Lei Youlan Zou Chunsheng Lu | 2017 | Theoretical & Applied Mechanics Letters2017，7，4： | 6 |
| 16 | Methods for optical phase retardation measurement:A review显示文摘Optical-phase-retardation elements are widely used in many fields.Accurate measurement of their phase retardation is crucial to the practical effect of the element's processing and application.The development and present situation of the methods for optical phase retardation measurement are reviewed,with the wave plate,the most typical phase-retardation element,as an example.The latest research progress in this field is introduced;the principles and characteristics of individual measurement method are summarized and discussed.Three new methods based on laser frequency splitting or laser feedback are presented in detail,in which the laser is not only regarded as a light source but also plays a role of sensor.Moreover,no standard wave plates are needed and arbitrary phase retardation can be measured.Traceability,high precision and high repeatability are achieved as well. | ZHANG Peng TAN YiDong LIU WeiXin CHEN WenXue | 2013 | Science China(Technological Sciences)2013，56，5： | 6 |
| 17 | The role of sphingosine-1-phosphate in bone remodeling and osteoporosis显示文摘Osteoporosis is a systemic bone disease that affects more than 200 million people worldwide and is caused by the disruption of the equilibrium between osteoclastic bone resorption and osteoblastic bone formation. Sphingosine-1-phosphate(S1 P) is a natural,bioactive sphingolipid that has been shown to play a major role in cardiovascular and immunological pathologies by regulating biological and cellular processes, including migration, differentiation, proliferation and survival. Recent studies also suggest a central role for S1 P in bone diseases, including osteoporosis;however, the effects of S1 P, particularly in bone metabolism, remain to be further elucidated. In this review, we summarize the available literature on the role of S1 P in bone metabolism with a focus on osteoporosis. On the cellular level, S1 P acts as an osteoclast-osteoblast coupling factor to promote osteoblast proliferation and bone formation. Moreover, the recruitment of osteoclast precursors to resorption sites is regulated by the interplay of S1 P gradients and S1 P receptor expression. From a clinical perspective, increasing evidence suggests that systemically elevated S1 P blood levels may serve as an independent risk factor for osteoporosis-related fractures. Taken together, S1 P signaling is a potential therapeutic target and may serve as a novel biomarker in patients with systemic bone disease. | Justus M.Grewe Paul-Richard Knapstein Antonia Donat Shan Jiang Daniel JSmit Weixin Xie Johannes Keller | 2022 | Bone Research2022，10，2： | 5 |
| 18 | Facile one-step synthesis of graphitic carbon nitride-modified biochar for the removal of reactive red 120 through adsorption and photocatalytic degradation显示文摘Converting waste biomass into value-added biochar has been considered as a green and sustainable strategy for resource management and pollution control.In this study,graphitic carbon nitride(g-C_(3)N_(4))modified biochars(BCs)were produced through one-pot pyrolysis of urea and hickory chips in differential ratios at 520℃.The resulting BC/g-C_(3)N_(4)composites were evaluated in laboratory for their physicochemical,adsorptive,and photocatalytic properties.The characterization tests showed the successful synthesis of the BC/g-C_(3)N_(4)composites that introduced g-C_(3)N_(4)structure,N-containing surface func-tional groups,reduced surface area,and better thermal stability to the biochar.After modification,the BC/g-C_(3)N_(4)composites showed better adsorption ability to reactive red 120(RR120)than the pristine BC,due to the strong electrostatic attrition between N-containing functional groups of g-C_(3)N_(4)on biochar surface and anionic RR120.The BC/g-C_(3)N_(4)composites also inherited g-C_(3)N_(4)’s photocatalytic activity,which is visible light responsive to generate free radicals for RR120 degradation.In addition,the composites with higher urea modification ratios were more effective in the degradation of RR120.Overall,this study demonstrates the feasibility and promising potential of combining biochar and photocatalyst for the removal of aqueous dye.Because of the synergistic adsorption and photodegradation ability,BC/g-C_(3)N_(4)composites present a novel and cost-effective solution for the removal of aqueous dye and other photodegradable contaminants under natural conditions. | Yulin Zheng Yichen Yang Yue Zhang Weixin Zou Yidan Luo Lin Dong Bin Gao | 2019 | Biochar2019，1，1： | 5 |

| 20 | Analyzing and quantitatively evaluating the organic matter source at different ecologic zones of tidal salt marsh, North Jiangsu Province, China显示文摘In order to explore the effect of different eco-logical zones and their above plants in the organic matter cycling of the whole tidal salt marsh,indicators such as total organic carbon(TOC),total nitrogen(TN),C/N ratio,δ13C and d15N of surface,core sediments,and plants of tidal salt marshes in North Jiangsu Province are analyzed.Subse-quently,distribution regularities of these measurement indi-cators are discussed,and the biogeochemistry processes between sediments and plants are also analyzed.Lastly,the organic matter sources of different ecologic zones in tidal salt marsh are evaluated,and the organic matter accumu-lations in different ecologic zones induced by their plants are also compared.These results indicate that TOC,TN,C/N ratio and δ13C showed obvious zonal distribution.The organic matter sources are dominated by marine input in the silt flat,artemisia schrenkiana flat,and the transition zone between silt and spartina alterniflora flat,and are controlled by terrigenous input in spartina alterniflora flat.Spartina alterniflora plays an important role in the accumulation of organic matter in the whole tidal salt marshes ecosystem.In the study area,the annually increased TOC,organic matter and TN in the spartina alterniflora,artemisia schrenkiana and reed flats reach 6,451,12,043 and 536 t,respectively.The amount of TOC,organic matter and TN accumulated in the spartina alterniflora flat is more than that in other ecological zones,which shows that the spartina alterniflora flat exert a non-replaceable effect on the material cycle and exchange in the whole tidal salt marshes ecosystem. | Jianhua GAO Guishan YANG Weixin OU | 2008 | Frontiers of Environmental Science & Engineering2008，2，1： | 5 |
