| 1 | Overexpression of CmMYB15 provides chrysanthemum resistance to aphids by regulating the biosynthesis of lignin显示文摘MYB transcription factors are widely involved in the development of and physiological processes in plants.Here,we isolated the chrysanthemum R2R3-MYB family transcription factor CmMYB15,a homologous gene of AtMYB15.It was demonstrated that CmMYB15 expression was induced by aphids and that CmMYB15 could bind to AC elements,which usually exist in the promoter of lignin biosynthesis genes.Overexpression of CmMYB15 in chrysanthemum enhanced the resistance of aphids.Additionally,the content of lignin and the expression of several lignin biosynthesis genes increased.In summary,the results indicate that CmMYB15 regulates lignin biosynthesis genes that enhance the resistance of chrysanthemum to aphids. | Cong An Liping Sheng Xinping Du Yinjie Wang Yi Zhang Aiping Song Jiafu Jiang Zhiyong Guan Weimin Fang Fadi Chen Sumei Chen | 2019 | Horticulture Research2019，6，1： | 6 |
| 2 | Effects of gravel mulch on aeolian transport:a field wind tunnel simulation显示文摘The shape,size and coverage of gravels have significant impacts on aeolian sand transport.This study provided an understanding of aeolian transport over the gravel mulching surfaces at different wind velocities by means of a mobile wind tunnel simulation.The tested gravel coverage increased from 5% to 80%,with a progressive increment of 5%.The gravels used in the experiments have three sizes in diameter.Wind velocities were measured using 10 sand-proof pitot-static probes,and mean velocity fields were obtained and discussed.The results showed that mean velocity fields obtained over different gravel mulches were similar.The analysis of wind speed patterns revealed an inherent link between gravel mulches and mean airflow characteristics on the gravel surfaces.The optimal gravel coverage is considered to be the critical level above or below which aeolian transport characteristics differ strongly.According to the present study,the optimal gravel coverage was found to be around 30% or 40%.Threshold velocity linearly increased with gravel coverage.Sand transport rate first increased with height above the wind tunnel floor(Hf),reaching a peak at some midpoint,and then decreased. | KeCun ZHANG WeiMin ZHANG LiHai TAN ZhiShan AN Hao ZHANG | 2015 | Journal of Arid Land2015，7，3： | 5 |
| 3 | Influence of MnS particles on the behaviors of grain boundary migration in Fe-3%Si alloys显示文摘The precipitation behaviors of MnS particles at 900℃ in a hot deformed Fe-3%Si alloy were observed statistically. The ratio of MnS particles on dislocations and in grain boundaries was calculated based on a model concerning the second phase precipitation in supersaturated solid solution. It was indicated that the precipitation of MnS particles on dislocations prevailed. The coarsening process of MnS particles in grain boundaries determined the boundary mobility during the secondary recrystallization. However, the density difference of precipitated MnS particles inside the grains on both sides of a boundary will determine the migration direction of the boundary as well, besides the grain size effect. It was observed that the densities of MnS particles in two neighboring grains were commonly different, and the boundary tended to move towards the area with lower particle density. The factors, e.g. dislocation densities in differently oriented grains will affect the density of precipitated particles, in which the Goss grains with higher particle density could grow more easily. | MAO WeiMin AN ZhiGuo LI ShuXia | 2009 | Chinese Science Bulletin2009，54，23： | 5 |
| 4 | Observed spatiotemporal variation of three-dimensional structure and heat/salt transport of anticyclonic mesoscale eddy in Northwest Pacific显示文摘As in-situ observations are sparse,targeted observations of a specific mesoscale eddy are rare.Therefore,it is difficult to study the three-dimensional structure of moving mesoscale eddies.From April to September 2014,an anticyclonic eddy located at 135°E-155°E,26°N-42°N was observed using 17 rapidsampling Argo floats,and the spatiotemporal variations in the three-dimensional structure were studied.The results are as follows:(1)the eddy was identified and tracked using satellite altimeter data.It had a lifetime of 269 days and an average radius of 91.5 km.The lifetime of the eddy can be divided into three phases,i.e.,the initiation,maturity,and termination phases.The depth of its influence reached 1000 m;(2)the Argo profiles were divided into seven periods(approximately 20 days in each)for composite analysis,and the composite Argo profiles and CARS2009(CSIRO Atlas of Regional Seas)climatology data were merged following the data-interpolating variational analysis(DIVA)method to reconstruct the three-dimensional structure.The temperature and salinity anomaly cores of the anticyclonic mesoscale eddy are located from 400 to 600 m.From 800 to 900 m,there is an area of low salinity at the center of the eddy.A high concentration anomaly of dissolved oxygen was located at approximately 250 m;(3)to better understand the features of the eddy and its interaction with the surroundings,we calculated the anomalous velocity of the geostrophic flow and the heat,salt,dissolved oxygen transport anomaly,and discussed the eddy's origin and its adjustments to topography.The maximum heat,salt,and oxygen transport caused by eddy were 9.37×10^11 W,3.08×10^3 kg/s,and 2.70×10^2 kg/s,which all occurred during the termination phase.This study highlights the applicability of using Argo floats to understand the three-dimensional structure thermohaline features of eddies in the North Pacific. | DAI Jun WANG Huizan ZHANG Weimin AN Yuzhu ZHANG Ren | 2020 | Journal of Oceanology and Limnology2020，38，6： | 5 |
| 5 | Analysis of solar radiation variations over Nanjing region in recent 40 years显示文摘The data utilized in this analysis consisted of extraterrestrial radiation, global radiation, d iffuse radiation, direct radiation, total cloud cover and relative suns hine. The annual variations and trend were analyzed for monthly mean daily total global, direct, and diffuse radiation on a horizontal surface and for the relations between global, direct, diffuse radiation and relative sunshine, tota l cloud cover. The climatological calculation equations of global and d irect radiation are put forward. The results show that global and dir ect radiations are characterized by decrease and diffuse radiation by increase. The main causes are due to the increase of concentration of suspended particles and atmospheric turbidities rather than cloud cover var iations. | ZHANG Yunlin,QIN Boqiang,CHEN Weimin(Nanjing Institute of Geography an d Limnology, CAS, Nanjing 210008, China) | 2003 | Journal of Geographical Sciences2003，13，1： | 3 |
| 6 | Noncontrast-enhanced MRI-based Noninvasive Score for Portal Hypertension(CHESS1802):An International Multicenter Study显示文摘Background and Aims:This study aimed to determine the performance of the non-invasive score using noncontrastenhanced MRI(CHESS-DIS score)for detecting portal hy-pertension in cirrhosis.Methods:In this international multicenter,diagnostic study(ClinicalTrials.gov,NCT03766880),patients with cirrhosis who had hepatic venous pressure gradient(HVPG)measurement and noncontrast-enhanced MRI were prospectively recruited from four university hospitals in China(n=4)and Turkey(n=1)between December 2018 and April 2019.A cohort of patients was retrospectively recruited from a university hospital in Italy between March 2015 and November 2017.After segmentation of the liver on fat-suppressed T1-weighted MRI maps,CHESS-DIS score was calculated automatically by an in-house developed code based on the quantification of liver surface nodularity.Results:A total of 149 patients were included,of which 124 were from four Chinese hospitals(training cohort)and 25 were from two international hospitals(validation cohort).A positive correlation between CHESS-DIS score and HVPG was found with the correlation coefficients of 0.36(p<0.0001)and 0.55(p<0.01)for the training and validation cohorts,respectively.The area under the receiver operating characteristic curve of CHESS-DIS score in detection of clinically significant portal hypertension(CSPH)was 0.81 and 0.9 in the training and validation cohorts,respectively.The intra-class correlation coefficients for assessing the inter-and intra-observer agreement were 0.846 and 0.841,respectively.Conclusions:A non-invasive score using noncontrast-enhanced MRI was developed and proved to be significantly correlated with invasive HVPG.Besides,this score could be used to detect CSPH in patients with cirrhosis. | Yanna Liu Tianyu Tang NecatiÖrmeci Yifei Huang Jitao Wang Xiaoguo Li Zhiwei Li Weimin An Dengxiang Liu Chunqing Zhang Changchun Liu Jinqiang Liu Chuan Liu Guangchuan Wang Cristina Mosconi Alberta Cappelli Antonio Bruno Seray Akçalar EmrecanÇelebioğlu EvrenÜstüner Sadık Bilgiç Zeynep Ellik ÖzgünÖmer Asiller Lei Li Haijun Zhang Ning Kang Dan Xu Ruiling He Yan Wang Yang Bu Ye Gu Shenghong Ju Rita Golfieri Xiaolong Qi | 2021 | Journal of Clinical and Translational Hepatology2021，9，6： | 3 |
| 7 | Synthesis of an ordered porous carbon with the dual nitrogen-doped interfaces and its ORR catalysis performance显示文摘Both nitrogen-doping feature and pore structure are critical factors for developing nitrogen-doped carbons based catalysts with a high performance toward oxygen reduction reaction(ORR).Herein,a simple one-step CVD of acetylene and acetonitrile vapor method using silanized SBA-15 as a template has been developed to synthesize an ordered porous carbon(OPC) with dual nitrogen-doped interfaces.The optimized sample as prepared with the CVD of 4 h at 750℃ contains two types of ordered mesopores that one type is the ordered cylindrical pores inheriting from the pores of SBA-15 and has a pore width of4.0~5.0 nm,the other type is the ordered quasi-hexagonal pores with a width of 3.0~4.0 nm produced by etching the pore walls of SBA-15.These two types of pores whose pore walls are built by the nitrogen doped carbon layers resulted by the CVD and thus it actually makes the dual nitrogen-doped interfaced OPC(DN-OPC).Meanwhile,DN-OPC contains a few of micropores and a large SSA of 1430 m~2/g.This dualordered pores and dual nitrogen-doped interfaces cannot only facilitate mass transport but also utilize the active sites of DN-OPC for ORR.Therefore,as metal-free ORR catalyst,DN-OPC exhibits a good activity close to commercial Pt/C catalyst,and an excellent durability and methanol tolerance. | Hongwei Zhao Yanqiu Zhang Li Lixiang Xin Geng Haiming Yang Weimin Zhou Chengguo Sun Baigang An | 2021 | Chinese Chemical Letters2021，32，1： | 2 |
| 8 | A novel strategy to derive iPS cells from porcine fibroblasts显示文摘Induced pluripotent stem (iPS) cell technology demonstrates that somatic cells can be reprogrammed to a pluripotent state by over-expressing four reprogramming factors.This technology has created an interest in deriving iPS cells from domesticated animals such as pigs,sheep and cattle.Moloney murine leukemia retrovirus vectors have been widely used to generate and study mouse iPS cells.However,this retrovirus system infects only mouse and rat cells,which limits its use in establishing iPS cells from other mammals.In our study,we demonstrate a novel retrovirus strategy to efficiently generate porcine iPS cells from embryonic fibroblasts.We transfected four human reprogramming factors (Oct4,Sox2,Klf4 and Myc) into fibroblasts in one step by using a VSV-G envelope-coated pantropic retrovirus that was easily packaged by GP2-293 cells.We established six embryonic stem (ES)-like cell lines in human ES cell medium supplemented with bFGF.Colonies showed a similar morphology to human ES cells with a high nuclei-cytoplasm ratio and phase-bright flat colonies.Porcine iPS cells could form embryoid bodies in vitro and differentiate into the three germ layers in vivo by forming teratomas in immunodeficient mice. | RUAN WeiMin HAN JianYong LI Pin CAO SuYing AN Yang LIM Bing LI Ning | 2011 | Science China(Life Sciences)2011，54，6： | 2 |
| 9 | A Knowledge Base System for Operation Optimization: Design and Implementation Practice for the Polyethylene Process显示文摘Setting up a knowledge base is a helpful way to optimize the operation of the polyethylene process by improving the performance and the ef ciency of reuse of information and knowledge two critical ele- ments in polyethylene smart manufacturing. In this paper, we propose an overall structure for a knowl- edge base based on practical customer demand and the mechanism of the polyethylene process. First, an ontology of the polyethylene process constructed using the seven-step method is introduced as a carrier for knowledge representation and sharing. Next, a prediction method is presented for the molecular weight distribution (MWD) based on a back propagation (BP) neural network model, by analyzing the relationships between the operating conditions and the parameters of the MWD. Based on this network, a differential evolution algorithm is introduced to optimize the operating conditions by tuning the MWD. Finally, utilizing a MySQL database and the Java programming language, a knowledge base system for the operation optimization of the polyethylene process based on a browser/server framework is realized. | Weimin Zhong Chaoyuan Li Xin Peng Feng Wan Xufeng An Zhou Tian | 2019 | Engineering2019，5，6： | 1 |
| 10 | Novel physical probe configurations in a multi-probe based 3D MIMO OTA setup显示文摘In this paper, channel spatial characteristics which mainly depend on the spatial correlation are selected as the significant factors in over-the-air(OTA) testing for multiple input multiple output(MIMO) devices. The multi-probe anechoic chamber method, a promising candidate of the MIMO OTA testing methods, can reproduce the multipath environments in a controllable manner. A novel physical configuration based on the variation of relative positions of probes in a MIMO OTA setup is put forward to obtain better spatial characteristics. Two physical configurations are presented to make a comparison with the typical configuration in this paper. The simulation results show that by making a proper probe configuration, good channel simulation accuracy can be achieved. Meanwhile, in order to get better performance of emulating channel spatial characteristics, probes in the first and the last probe rings should be placed symmetrically in three dimensional(3D) physical probe configuration. | Wang Weimin Li Muyuan Liu Yuan'an Wu Yongle Li Shulan | 2017 | The Journal of China Universities of Posts and Telecommunications2017，24，1： | 1 |

| 12 | Crystallization of Al-based Amorphous Alloys in Good Conductivity Solution显示文摘The corrosion-induced crystallization of Al94 exNixGd6(x=6 and 10, in at.%) metallic glasses as well as phase separation, oxidation and cracking in good conductivity solution has been investigated by various techniques.The transmission electronic microscopy(TEM) result reveals that crystalline intermetallics and oxides present on the electrochemically thinned hole edge, and the phase separation occurs in the matrix of the as-spun ribbons with the circumferential speed Rcof 29.3 m/s. In addition, the bending and cracking of the samples occur after corrosion. The influence of Ni content on the phase separation, bending and cracking can be explained by the fact that the percolation of the backbone clusters in the amorphous alloy melts and glasses is enhanced by increasing the composition of Ni. | Yonggang Wang Yan Liu Yingjie Li Bang An Guanghui Cao Shifeng Jin Yimin Sun Weimin Wang | 2014 | Journal of Materials Science & Technology2014，30，12： | 1 |
| 13 | Effect of Compression on the Crystallization Behavior and Corrosion Resistance of Al_(86)Ni_9La_5 Amorphous Alloy显示文摘The effect of compression on the crystallization behavior and corrosion resistance of Al(86)Ni9La5 amorphous ribbons was investigated by X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning elec-tron microscopy (SEM) and electrochemistry test. The XRD and TEM results reveal that the compressed Al(86)Ni9La5 ribbons spun with the circumferential speed (R) of 29.3 m/s are in fully amorphous state; however, the compressed ribbons spun with R=14.7 m/s have crystalline phases embedded in the amorphous matrix. The SEM images indicate that after compression, the toughness of the ribbons increases. Electrochemical results show that the compression decreases the stability of the passive film of the Al(86)Ni9La5 amorphous ribbons, because of the compression-introduced free volume, shear bands and crystalline phases; meanwhile, with R=14.7 m/s, the compression-induced crystalline phases in the Al(86)Ni9La5 ribbons increase the corrosion potential. | Yan Liu Weimin Wang Hongdi Zhang Haitian Ma Bang An | 2012 | Journal of Materials Science & Technology2012，28，12： | 1 |
| 14 | Morphological variation of star dune and implications for dune management: a case study at the Crescent Moon Spring scenic spot of Dunhuang, China显示文摘Aerial photographs and 3-D laser scans of a 90-m high star dune at the Crescent Moon Spring scenic spot in Dunhuang,China,are used to investigate the changes in dune morphology on timescales from months to decades.The result revealed that relative-equilibrium airflow strength in three wind directions of northeast,west and south was an important condition for the stability of star dunes with limited migration.Transverse and longitudinal airflows exerted a crucial impact on variation processes of star dune morphology.Controlled by transverse airflows,the easterly winds,the east side was dominated by wind erosion;and strong deposition occurred on the south-south-east arm with a maximum deposition rate of 0.44 m/a in the 46-a monitoring period,causing the east side becoming steep and high.Controlled by longitudinal airflows,the westerly winds,the west-north-west side was mainly eroded and the north arm migrated from west to east with a rate of 0.30 m/a,causing the dune slope becoming gentle and elongate.The local air circulation(southerly winds)exerted a significant impact on the development process of the star dune.Due to the influence of human activities,the south side present surface processes from a concave profile to a convex profile in 46 a,which is a potential threat to the Crescent Moon Spring.The results indicate that rehabilitating the airflow field at most is a crucial strategy to the protection of Crescent Moon Spring from burial.Opening up the passage of easterly,westerly and southerly winds through intermediately cutting the protection forest,demolishing the enclosed wall and changing the pavilion into a porous pattern have been suggested to protect the Crescent Moon Spring from burial. | ZHANG Weimin TAN Lihai AN Zhishan ZHANG Kecun GAO Yang NIU Qinghe | 2019 | Journal of Arid Land2019，11，3： | 1 |

| 18 | Tissue Plasminogen Activator and Glaucoma显示文摘Ⅰ.Introduction Tissue Plasminogen Activator (tPA) is a new clot-specific fibrinolytic agent, developed through gene cloning. It is a 70,000 dalton serine protease with 527 amino acids and 3 saccharic chains. The tPA- fibrin complex specifically activates plasminogen into plasmin, which in turn degrades fibrin into solube split products. Because of its selectivity for fibrin-bound plasminogen, tPA promotes local lysis, instead of the systemic fibrinolytic state promoted by streptokinase and urokinase. | Summarized by Changmei Guo Department of Ophthalmology,First Teaching Hospital,XI’an Jiapxong Uniersity,Xi’an 710061 P.R.China, Weimin Hu , Revised by Shouxin CTDepartment,PLA323 Hpsoital,Xi’an 710054 P.R.China Cui Ying LiDepartment of Foreign Languages,Xi’an Jiaotong Univerasity,Xi’an 710061 P.R.China. | 2000 | 国际眼科杂志2000，2，1： | 1 |
| 19 | Thymol ameliorates ammonium toxicity via repressing polyamine oxidase-derived hydrogen peroxide and modulating ammonium transporters in rice root显示文摘Background:Ammonium is an indispensable nutrient for crop growth,but anoxic conditions or inappropriate fertilizer usage result in the increase in ammonium content in soil.Excessive ammonium causes phytotoxicity.Thymol is a kind of natural phenolic compound with anti-microbial properties.However,little is known about the role of thymol in modulating plant physiology.Here we find the novel role of thymol in protecting rice from ammonium toxicity.Results:Thymol remarkably rescued rice seedlings growth from ammonium stress,which may resulted from the attenuation of reactive oxygen species(ROS)accumulation,oxidative injury,and cell death in both shoots and roots.Polyamine oxidase(PAO)metabolizes polyamines to produce ROS in plants in response to stress conditions.Thymol blocked ammonium-induced upregulation of a set of rice PAOs,which contributed to the decrease in ROS content.In rice seedlings upon ammonium stress,thymol downregulate the expression of ammonium transporters(AMT1;1 and AMT1;2);thymol upregulated the expression of calcineurin B-like interacting protein kinase 23(CIPK23)and calcineurin B-like binding protein 1(CBL1),two negative regulators of AMTs.This may help rice avoid ammonium overload in excessive ammonium environment.Correlation analysis indicated that PAOs,AMTs,and CBL1 were the targets of thymol in the detoxification of excessive ammonium.Conclusion:Thymol facilitates rice tolerance against ammonium toxicity by decreasing PAO-derived ROS and modulating ammonium transporters.Such findings may be applicable in the modulation of nutrient acquisition during crop production. | Kai Guo Guangchi An Ning Wang Bingdong Pang Zhiqi Shi Hongwu Bai Li Zhang Jian Chen Weimin Xu | 2021 | Food Production, Processing and Nutrition2021，3，1： | 0 |
