| 3 | High-entropy ceramics:Present status,challenges,and a look forward显示文摘High-entropy ceramics (HECs) are solid solutions of inorganic compounds with one or more Wyckoff sites shared by equal or near-equal atomic ratios of multi-principal elements.Although in the infant stage,the emerging of this new family of materials has brought new opportunities for material design and property tailoring.Distinct from metals,the diversity in crystal structure and electronic structure of ceramics provides huge space for properties tuning through band structure engineering and phonon engineering.Aside from strengthening,hardening,and low thermal conductivity that have already been found in high-entropy alloys,new properties like colossal dielectric constant,super ionic conductivity,severe anisotropic thermal expansion coefficient,strong electromagnetic wave absorption,etc.,have been discovered in HECs.As a response to the rapid development in this nascent field,this article gives a comprehensive review on the structure features,theoretical methods for stability and property prediction,processing routes,novel properties,and prospective applications of HECs.The challenges on processing,characterization,and property predictions are also emphasized.Finally,future directions for new material exploration,novel processing,fundamental understanding,in-depth characterization,and database assessments are given. | Huimin XIANG Yan XING Fu-zhi DAI Hongjie WANG Lei SU Lei MIAO Guojun ZHANG Yiguang WANG Xiwei QI Lei YAO Hailong WANG Biao ZHAO Jianqiang LI Yanchun ZHOU | 2021 | Journal of Advanced Ceramics2021，10，3： | 28 |

| 5 | A structural view of the antibiotic degradation enzyme NDM-1 from a superbug显示文摘Gram-negative Enterobacteriaceae with resistance to carbapenem conferred by New Delhi metallo-β-lactamase 1(NDM-1)are a type of newly discovered antibioticresistant bacteria.The rapid pandemic spread of NDM-1 bacteria worldwide(spreading to India,Pakistan,Europe,America,and Chinese Taiwan)in less than 2 months characterizes these microbes as a potentially major global health problem.The drug resistance of NDM-1 bacteria is largely due to plasmids containing the blaNDM-1 gene shuttling through bacterial populations.The NDM-1 enzyme encoded by the blaNDM-1 gene hydrolyzes β-lactam antibiotics,allowing the bacteria to escape the action of antibiotics.Although the biological functions and structural features of NDM-1 have been proposed according to results from functional and structural investigation of its homologues,the precise molecular characteristics and mechanism of action of NDM-1 have not been clarified.Here,we report the threedimensional structure of NDM-1 with two catalytic zinc ions in its active site.Biological and mass spectroscopy results revealed that D-captopril can effectively inhibit the enzymatic activity of NDM-1 by binding to its active site with high binding affinity.The unique features concerning the primary sequence and structural conformation of the active site distinguish NDM-1 from other reported metallo-β-lactamases(MBLs)and implicate its role in wide spectrum drug resistance.We also discuss the molecular mechanism of NDM-1 action and its essential role in the pandemic of drug-resistant NDM-1 bacteria.Our results will provide helpful information for future drug discovery targeting drug resistance caused by NDM-1 and related metallo-β-lactamases. | Yu Guo Jing Wang Guojun Niu Wenqing Shui Yuna Sun Honggang Zhou Yaozhou Zhang Cheng Yang Zhiyong Lou Zihe Rao | 2011 | Protein & Cell2011，2，5： | 16 |
| 6 | Chlorite cement and its effect on the reservoir quality of sandstones from the Panyu low-uplift,Pearl River Mouth Basin显示文摘Based on porosity and permeability measurements,mercury porosimetry measurements,thin section analyses,SEM observations,X-ray diffraction(XRD) analysis and granulometric analyses,diagenetic features of reservoir sandstones taken from the Zhuhai formation in the Panyu low-uplift of the Pear River Mouth Basin were examined.This study shows that chlorite cements are one of the most important diagenetic features of reservoir sandstones.The precipitation of chlorite was controlled by multiple factors and its development occurred early in eo-diagenesis and continued till Stage A of middle diagenesis.The precipitation of chlorite at the early stage was mainly affected by the sedimentary environment and provenance.Abundant Fe-and Mg-rich materials were supplied during the deposition of distributary channel sediments in the deltaic front setting and mainly in alkaline conditions.With the burial depth increasing,smectite and kaolinite tended to be transformed into chlorite.Smectite cements were completely transformed into chlorite in sandstones of the studied area.Volcanic lithics rich in Fe and Mg materials were dissolved and released Fe2+ and Mg 2+ into the pore water.These cations precipitated as chlorite cements in middle diagenesis in an alkaline diagenetic environment.Chlorite coatings acted as porosity and permeability,thus helping preserve cements in the chlorite cemented sandstones.The reservoir quality of chlorite cemented sandstones is much better than sandstones without chlorite cements.Chlorite cements play an important role in the reservoir evolution that was mainly characterized by preserving intergranular porosity and forming better pore-throat structures of sandstones. | Chen Guojun Du Guichao Zhang Gongcheng Wang Qi Lv Chengfu | 2011 | Petroleum Science2011，8，2： | 14 |

| 8 | The GW2-WG1-OsbZIP47 pathway controls grain size and weight in rice显示文摘Regulation of seed size is a key strategy for improving crop yield and is also a basic biological question.However,the molecular mechanisms by which plants determine their seed size remain elusive.Here,we report that the GW2-WG1-OsbZIP47 regulatory module controls grain width and weight in rice.WG1,which encodes a glutaredoxin protein,promotes grain growth by increasing cell proliferation.Interestingly,WG1 interacts with the transcription factor OsbZIP47 and represses its transcriptional activity by associating with the transcriptional co-repressor ASP1,indicating that WG1 may act as an adaptor protein to recruit the transcriptional co-repressor.In contrary,OsbZIP47 restricts grain growth by decreasing cell proliferation.Further studies reveal that the E3 ubiquitin ligase GW2 ubiquitinates WG1 and targets it for degradation.Genetic analyses confirm that GW2,WG1,and OsbZIP47 function in a comm on pathway to control grain growth.Taken together,ourfindi ngs reveal a genetic and molecular framework for the control of grain size and weight by the GW2-WG1-OsbZIP47 regulatory module,providing new targets for improving seed size and weight in crops. | Jianqin Hao Dekai Wang Yingbao Wu Ke Huang Penggen Duan Na Li Ran Xu Dali Zeng Guojun Dong Baolan Zhang Limin Zhang Dirk Inze Qian Qian Yunhai Li | 2021 | Molecular Plant2021，14，8： | 14 |
| 9 | Static Extracting Method of Software Intended Behavior Based on API Functions Invoking显示文摘The method of extracting and describing the intended behavior of software precisely has become one of the key points in the fields of software behavior's dynamic and trusted authentica-tion. In this paper,the author proposes a specified measure of ex-tracting SIBDS (software intended behaviors describing sets) statically from the binary executable using the software's API functions invoking,and also introduces the definition of the struc-ture used to store the SIBDS in detail. Experimental results dem-onstrate that the extracting method and the storage structure defi-nition offers three strong properties: (i) it can describe the soft-ware's intended behavior accurately; (ii) it demands a small stor-age expense; (iii) it provides strong capability to defend against mimicry attack. | PENG Guojun PAN Xuanchen FU Jianming ZHANG Huanguo | 2008 | Wuhan University Journal of Natural Sciences2008，13，5： | 11 |
| 10 | Lithospheric structure and faulting characteristics of the Helan Mountains and Yinchuan Basin: Results of deep seismic reflection profiling显示文摘The Helan Mountains and Yinchuan Basin(HM-YB) are located at the northern end of the North-South tectonic belt,and form an intraplate tectonic deformation zone in the western margin of the North China Craton(NCC).The HM-YB has a complicated history of formation and evolution,and is tectonically active at the present day.It has played a dominant role in the complex geological structure and modern earthquake activities of the region.A 135-km-long deep seismic reflection profile across the HM-YB was acquired in early 2014,which provides detailed information of the lithospheric structure and faulting characteristics from near-surface to various depths in the region.The results show that the Moho gradually deepens from east to west in the depth range of 40-48 km along the profile.Significant differences are present in the crustal structure of different tectonic units,including in the distribution of seismic velocities,depths of intra-crustal discontinuities and undulation pattern of the Moho.The deep seismic reflection profile further reveals distinct structural characteristics on the opposite sides of the Helan Mountains.To the east,The Yellow River fault,the eastern piedmont fault of the Helan Mountains,as well as multiple buried faults within the Yinchuan Basin are all normal faults and still active since the Quaternary.These faults have controlled the Cenozoic sedimentation of the basin,and display a 'negative-flower' structure in the profile.To the west,the Bayanhaote fault and the western piedmont fault of the Helan Mountains are east-dipping thrust faults,which caused folding,thrusting,and structural deformation in the Mesozoic stratum of the Helan Mountains uplift zone.A deep-penetrating fault is identified in the western side of the Yinchuan Basin.It has a steep inclination cutting through the middle-lower crust and the Moho,and may be connected to the two groups of faults in the upper crust.This set of deep and shallow fault system consists of both strike-slip,thrust,and normal faults formed over different eras,and provides the key tectonic conditions for the basin-mountains coupling,crustal deformation and crust-mantle interactions in the region.The other important phenomenon revealed from the results of deep seismic reflection profiling is the presence of a strong upper mantle reflection(UMR) at a depth of 82-92 km beneath the HM-YB,indicating the existence of a rapid velocity variation or a velocity discontinuity in that depth range.This is possibly a sign of vertical structural inhomogeneity in the upper mantle of the region.The seismic results presented here provide new clues and observational bases for further study of the deep structure,structural differences among various blocks and the tectonic relationship between deep and shallow processes in the western NCC. | LIU BaoJin FENG ShaoYing JI JiFa WANG ShuaiJun ZHANG JianShi YUAN HongKe YANG GuoJun | 2017 | Science China Earth Sciences2017，60，3： | 11 |
| 11 | Microstructure and Mechanical Properties of Multilayer Ti(C,N) Films by Closed-field Unbalanced Magnetron Sputtering Ion Plating显示文摘Ti(C, N) multilayer films have been prepared by closed-field unbalanced magnetron sputtering technology and using graphite target as the C supplier. Microstructural observation results showed that the Ti(C, N) films exhibited multilayer structure with most of fine nano-columnar Ti(C, N) grains existing in the films. The current of graphite target had an effect remarkably on the multilayer structure of films: the periodical thickness gradually increased as the current went up, but the grain size of films gradually decreased and even amorphous phase appeared as the current further increased. The microstructure of Ti(C, N) films changed from columnar crystallite to nanocomposite in high current of graphite target where the fine Ti(C, N) grains were distributed uniformly in the amorphous Ti(C, N) matrix, and the volume fraction of the amorphous phase increased with increasing current. Measurement results showed that the Ti(C, N) multilayer films have high microhardness and low friction coefficient, and especially the film deposited in the current of 0.9 A exhibits superior properties with optimizing hardness and friction coefficient. Based on the relationship of the microstructure and the properties of films, the multilayer structure and fine grain size of Ti(C, N) films are responsible for their well mechanical and friction properties. And choosing the graphite target as the C supplier is more propitious to decrease the friction coefficients of films. | Guojun Zhang Bin Li Bailing Jiang Dichun Chen Fuxue Yan | 2010 | Journal of Materials Science & Technology2010，26，2： | 11 |
| 12 | Structural evolution of non dendritic AlSi7Mg alloy during reheating显示文摘The structural evolution of non dendritic AlSi7Mg alloy during reheating in resistance furnace was studied. The alloy ingots were produced by electromagnetic stirring during solidification. It was found that, the Si phase in eutectic dissolves in a way of diffusion toward α phase, its appearance changes from flake to dot like, and tends to be fine and spheroidal with increasing reheating temperature. The thinner the flake, the lower the temperature for the occurrence of this process, and the higher the transforming speed. The eutectic melts partially when Si phase dissolves to some extent, and the morphology and size of primary α phase begin to change. The dendrite and rosette α phases tends to sphericize. The size of the former becomes larger, while the size of the latter reduces to be 1/2~1/4 of the original size. The spheroidal primary α phase has a tendency of grain growth. | Zhang Kui(张奎) Zhang Yongzhong(张永忠) Liu Guojun(刘国均) Xu Jun(徐骏) Zhang Jingxin(张景新) Fan Jianzhong(樊建中) Shi Likai(石力开) | 1999 | 中国有色金属学会会刊:英文版1999，9，3： | 10 |
| 13 | Temperature field distribution of burnt surrounding rock in UCG stope显示文摘In order to study temperature field distribution in burnt surrounding rock and to determine ranges of burnt surrounding rock, coal-wall coking cycle and heat influence in the underground coal gasification(UCG) stope, based on the Laplace transform and inversion formula, we studied the temperature analytical solution of one-dimensional unsteady heat conduction for multi-layer overlying strata under the first and the forth kinds of boundary conditions, and we also carried out a numerical simulation of twodimensional unsteady heat conduction by the COMSOL multiphysics. The results show that when the boundary temperature of surrounding rock has a linear decrease because of a directional movement of heat source in the UCG flame working face, the temperature in surrounding rock increases first and then decreases with time, the peak of temperature curve decreases gradually and its position moves inside surrounding rock from the boundary. In the surrounding rock of UCG stope, there is an envelope curve of temperature curve clusters. We analyzed the influence of thermophysical parameters on envelope curves and put forward to take envelope curve as the calculation basis for ranges of burnt surrounding rock, coal-wall coking cycle and heat influence. Finally, the concrete numerical values are given by determining those judgement standards and temperature thresholds, which basically tally with the field geophysical prospecting results. | Xin Lin Wang Zuotang Huang Wengang Kang Guojun Lu Xuefeng Zhang Peng Wang Jianhua | 2014 | International Journal of Mining Science and Technology2014，24，4： | 10 |
| 14 | The Ghd7 transcription factor represses ARE1 expression to enhance nitrogen utilization and grain yield in rice显示文摘The genetic improvement of nitrogen use efficiency(NUE)of crops is vital for grain productivity and sustainable agriculture.However,the regulatory mechanism of NUE remains largely elusive.Here,we report that the rice Grain number,plant height,and heading date7(Ghd7)gene genetically acts upstream of ABC1 REPRESSOR1(ARE1),a negative regulator of NUE,to positively regulate nitrogen utilization.As a transcriptional repressor,Ghd7 directly binds to two Evening Element-like motifs in the promoter and intron 1 of ARE1,likely in a cooperative manner,to repress its expression.Ghd7 and ARE1 display diurnal expression patterns in an inverse oscillation manner,mirroring a regulatory scheme based on these two loci.Analysis of a panel of 2656 rice varieties suggests that the elite alleles of Ghd7 and ARE1 have undergone diversifying selection during breeding.Moreover,the allelic distribution of Ghd7 and ARE1 is associated with the soil nitrogen deposition rate in East Asia and South Asia.Remarkably,the combination of the Ghd7 and ARE1 elite alleles substantially improves NUE and yield performance under nitrogen-limiting conditions.Collectively,these results define a Ghd7–ARE1-based regulatory mechanism of nitrogen utilization,providing useful targets for genetic improvement of rice NUE. | Qing Wang Qingmei Su Jinqiang Nian Jian Zhang Meng Guo Guojun Dong Jiang Hu Rongsheng Wang Changshuo Wei Guanwen Li Wan Wang Hui-Shan Guo Shaoyang Lin Wenfeng Qian XianzhiXie Qian Qian Fan Chen Jianru Zuo | 2021 | Molecular Plant2021，14，6： | 10 |
| 15 | M1 muscarinic acetylcholine receptor in Alzheimer's disease显示文摘The degeneration of cholinergic neurons and cholinergic hypofunction are pathologies associated with Alzheimer's disease(AD). Muscarinic acetylcholine receptors(mAChRs) mediate acetylcholine-induced neurotransmission and five mAChR subtypes(M1–M5) have been identified. Among them, M1 mAChR is widely expressed in the central nervous system and has been implicated in many physiological and pathological brain functions. In addition, M1 mAChR is postulated to be an important therapeutic target for AD and several other neurodegenerative diseases. In this article, we review recent progress in understanding the functional involvement of M1 mAChR in AD pathology and in developing M1 mAChR agonists for AD treatment. | Shangtong Jiang Yanfang Li Cuilin Zhang Yingjun Zhao Guojun Bu Huaxi Xu Yun-Wu Zhang | 2014 | Neuroscience Bulletin2014，30，2： | 10 |
| 16 | Characteristics and dynamics analysis of Populus euphratica populations in the middle reaches of Tarim River显示文摘Populus euphratica Oliv. is widely distributed along the Tarim River. Maintaining stability of P. euphratica population is important to local development. This study explored the static life table, survivorship curves and four function curves (survival rate, cumulative mortality rate, mortality density, and hazard rate), and development index of P. euphratica population in the middle reaches of Tarim River. The results indicated that the age structure of P. euphratica population belonged to positive pyramidal type, which meant young age-class individuals occupied most populations. The number ofⅠ-Ⅱage classes accounted for 66.2% of whole population, and this indicated that there were abundant subsequent seedlings resources to support the growth of P. euphratica population in the middle reaches of Tarim River. The survivorship curve of P. euphratica belonged to the Deevey Ⅲ (concave-type) and the development index was 47.72%. Four function curves revealed that the individuals of P. euphratica sharply decreased at the initial stage and then leveled off at the late stage of survival curve. Time sequence prediction models predicted that the number of midlife individuals would increase in future 10, 20, 30 years, and P. euphratica population grew steadily as a result of rich saplings. | Wu, JunXia Zhang, XiMing Deng, ChaoZhou Liu, GuoJun Li, Hong | 2010 | Journal of Arid Land2010，2，4： | 9 |
| 17 | ADAPTABLE DESIGN OF MACHINE TOOLS STRUCTURES显示文摘Adaptable design aims to extend the utilities of design and product.The specific methods are developed for practical applications of adaptable design in the design of mechanical structures, including adaptable platform,interface and module designs.Adaptable redesign problems are formulated as adaptable platform design under adaptability bound constraints.Analysis tools are then suggested for the implementation of the redesign of machine tool structures,including variation techniques based sensitivity analysis,similarity-based commonality analysis,performance improvement,and adaptability measures.The specific measure of adaptability for machine tool structures is measured through the quantification of the structural similarity and performance improvement gained from adaptable design.The method provides designers with an approach that brings adaptability into the design process,with considering the cost and benefits of such adaptability. The redesign of CNC spiral bevel gear cutting machine structures has been included to illustrate these concepts and methods. | XU Yanshen CHEN Yongliang ZHANG Guojun GU Peihua | 2008 | Chinese Journal of Mechanical Engineering2008，21，3： | 9 |
| 18 | Impending HRT wave precursors to the Wenchuan M_s8.0 earthquake and methods of earthquake impending prediction by using HRT wave显示文摘We deployed four geo-electric monitoring stations in Sichuan and Yunnan provinces from 2004, using the new generation of equipment (PS-100) and technologies to capture the HRT wave earthquake precursor. Before the Wenchuan Ms8.0 earthquake, we recorded the HRT wave precursor at the only operating station in Hongge (HG, Δ=465 km) and found that significant impending signal had been recorded at the station in the early morning ( 0―5 am) of 12th of May, 2008. The precursor for this earthquake is consistent with precursors recorded for other strong earthquakes. The measured physical properties (geo-resistivity and telluric-current) show tidal wave period oscillations from several days to several months before the earthquakes and the amplitude of such HT oscillation increases significantly towards the occurrence of an earthquake. These HT and RT waves from the epicenter have a causal relationship with the earthquakes that happened several days later. The arrival time of two RT waves is proportional to the distance from the station to the epicenter. The estimated natural decay of the amplitude is correlated with the natural period (T0) of the earthquake fault, which is proportional to the fault length. From this relationship, we can predict the earthquake magnitude. For magnitude 6―9 earthquakes, the natural period is about 1―6 hours. Such oscillation comes from the epicenter area and they can propagate several thousand kilometers in the Earth's crust. Before a strong earthquake in the shallow crust, the conductive pore fluid will experience major changes before the fault rapture. Such fluid change will emit an oscillation in the pore fluid pressure. This is the mechanism for the HRT wave generation. Since the China Earthquake Administration funded the HRT wave short-term earth-quake prediction project in 2003, the first record of HRT precursor wave has been recorded from the 2004-12-26 Sumatra Mw9.0 earthquake with the largest epicentre distance Δ=2900 km. Thereafter, we have captured HRT waves from more than twenty strong earthquakes, which are well-matched and show repeatability, consistency and regularity. All our observation with the HRT waves demonstrate that HRT wave precursors to earthquakes indeed exist. Strong earthquakes can be predicted and short-term and impending earthquake prediction is achievable in the very near future. From all the observations, including the ones at HG station from Wenchuan Ms8.0 earthquake, we conclude that using HRT wave to predict earthquakes is feasible. | QIAN FuYe ZHAO BiRu QIAN Wei ZHAO Jian HE ShiGen ZHANG HongKui LI ShiYu LI ShaoKun YAN GuLiang WANG ChengMin SUN ZhenKai ZHANG DongNing LU Jun ZHANG Ping YANG GuoJun SUN JiaLin GUO ChunSheng TANG YuXiong XU JianMing XIA KunTao JU Hang YIN BangHong LI Ming YANG DongSheng QI WeiLuo HE TaiMing GUAN HuaPing ZHAO YuLin | 2009 | Science China Earth Sciences2009，52，10： | 8 |
| 19 | Characterization and fine mapping of an early senescence mutant (es-t) in Oryza sativa L.显示文摘An es-t (early senescence-temporary) mutant, produced by ethylene methylsulfonate treatment of strain Nipponbare, was identified in rice. The leaves of es-t appeared yellow at the seedling stage, and had decreased chlorophyll content. Rust spots were found during growth in es-t, especially at the leaf margin and tip. The plants showed a typical early-senescence phenotype at the milky stage. The leaf surface of es-t appeared smoother than wild-type leaves under a scanning electron microscope, because the leaves lack siliceous protuberances around the stoma. Chloroplasts grow abnormally and are filled with many starch grains in es-t. Paraffin section analysis showed that the development of the sclerenchyma cells and vascular bundles were also abnormal in es-t. Genetic analysis indicated that es-t was controlled by a recessive gene, which was finely mapped to a 42-kb interval on chromosome 5. These results will facilitate the positional cloning and functional studies of the gene. | YANG YaoLong RAO YuChun LIU HuiJuan FANG YunXia DONG GuoJun HUANG LiChao LENG YuJia GUO LonBiao ZHANG GuangHeng HU Jiang GAO ZhenYu QIAN Qian ZENG DaLi | 2011 | Chinese Science Bulletin2011，56，23： | 8 |
