| 1 | China's lakes at present:Number,area and spatial distribution显示文摘Based on 11004 satellite images from CBERS CCD and Landsat TM/ETM,changes in the spatial characteristics of all lakes in China were determined following pre-established interpretation rules.This dataset was supported by 6843 digital raster images(1:100000 and 1:50000),a countrywide digital vector dataset(1:250000),and historical literature.Comparative data were corrected for seasonal variations using precipitation data.There are presently 2693 natural lakes in China with an area greater than 1.0 km2,excluding reservoirs.These lakes are distributed in 28 provinces,autonomous regions and municipalities and have a total area of 81414.6 km2,accounting for-0.9% of China's total land area.In the past 30 years,the number of newly formed and newly discovered lakes with an area greater than 1.0 km2 is 60 and 131,respectively.Conversely,243 lakes have disappeared in this time period. | MA RongHua YANG GuiShan DUAN HongTao JIANG JiaHu WANG SuMin FENG XueZhi LI AiNong KONG FanXiang XUE Bin WU JingLu LI ShiJie | 2011 | Science China Earth Sciences2011，54，2： | 79 |
| 2 | Analytical Solutions of Cracks Emanating from an Elliptic Hole in an Infinite Plate under Tension显示文摘It is a common phenomenon that the cracks originating from a hole can cause structural damage in engineering.However,the fracture mechanics studies of hole edge crack problems are not sufficient.The problem of an elliptical hole with two collinear edge cracks of unequal length in an infinite plate under uniform tension at infinity is investigated.Based on the complex variable method,the analytical solutions of stress functions and stress intensity factors are provided.The stress distribution along the axes and the edge of the elliptical hole is given graphically.The numerical results show that there is obvious stress concentration near the hole and cracks,and the stresses tend to applied loads at distances far from the defect,which conform to Saint-Venant’s principle.Hence,the stress functions are proved to be right.Under special conditions,the present configuration becomes the Griffith crack,two symmetrical cracks emanating from an elliptical hole,two cracks of unequal length emanating from a circular hole,a crack at the edge of a circular hole,or a crack emanating from an elliptical hole.Compared with available results,stress intensity factors for these special shapes of ellipses and cracks show good coincidence.The stress intensity factor for two cracks of unequal length at the edge of an elliptical hole increases with the crack length and the major-to-minor axis ratio of the elliptical hole.The stress distribution in an infinite plate containing an elliptic hole with unsymmetrical cracks is given for the first time. | LIU Shuhong DUAN Shijie | 2014 | Chinese Journal of Mechanical Engineering2014，27，5： | 8 |
| 3 | Electro-elastic Fields of Piezoelectric Materials with An Elliptic Hole under Uniform Internal Shearing Forces显示文摘The existing investigations on piezoelectric materials containing an elliptic hole mainly focus on remote uniform tensile loads. In order to have a better understanding of the fracture behavior of piezoelectric materials under different loading conditions, theoretical and numerical solutions are presented for an elliptic hole in transversely isotropic piezoelectric materials subjected to uniform internal shearing forces based on the complex potential approach. By solving ten variable linear equations, the analytical solutions inside and outside the hole satisfying the permeable electric boundary conditions are obtained. Taking PZT-4 ceramic into consideration, numerical results of electro-elastic fields along the edge of the hole and axes, and the electric displacements in the hole are presented. Comparison with stresses in transverse isotropic elastic materials shows that the hoop stress at the ends of major axis in two kinds of material equals zero for the various ratios of major to minor axis lengths; If the ratio is greater than 1, the hoop stress in piezoelectric materials is smaller than that in elastic materials, and if the ratio is smaller than 1, the hoop stress in piezoelectric materials is greater than that in elastic materials; When it is a circle hole, the shearing stress in two materials along axes is the same. The distribution of electric displacement components shows that the vertical electric displacement in the hole and along axes in the material is always zero though under the permeable electric boundary condition; The horizontal and vertical electric displacement components along the edge of the hole are symmetrical and antisymmetrical about horizontal axis, respectively. The stress and electric displacement distribution tends to zero at distances far from the elliptical hole, which conforms to the conclusion usually made on the basis of Saint-Venant's principle. Unlike the existing work, uniform shearing forces acting on the edge of the hole, and the distribution of electro-elastic fields inside and outside the elliptic hole are considered. | DU Yanliang LIU Shuhong DUAN Shijie LI Yanqiang | 2013 | Chinese Journal of Mechanical Engineering2013，26，3： | 6 |
| 4 | Consensus seeking in multiagent cooperative control systems with bounded control input显示文摘Consensus algorithms in multiagent cooperative control systems with bounded control input are studied in this paper.Consensus algorithms are considered for the single-integrator dynamics and double-integrator dynamics under different communication interaction topologies,and show that consensus is reached asymptotically using the algorithm proposed in this paper for the single-integrator dynamics if the undirected interaction graph is connected,and consensus is reached asymptotically if the directed interaction graph is strongly connected,respectively.In addition,the paper further shows that consensus is reached asymptotically using the algorithm proposed for the double-integrator dynamics if the directed interaction graph is strongly connected.The effectiveness of these algorithms is demonstrated through simulations. | Zhang, Shijie Duan, Guangren | 2011 | 控制理论与应用(英文版)2011，9，2： | 5 |
| 5 | Analytical solutions of cracks emanating from an elliptical hole under shear显示文摘Based on the complex variable method, the analytical solutions of stress functions and stress intensity factors(SIFs) are provided for the plane problem of two collinear edge cracks emanating from an elliptical hole in an infinite plate under shear. The stress distribution along the horizontal axis is given in graphical forms, which conforms to Saint-Venant's principle. The influences of crack length and ellipse shape on the stress intensity factors are evaluated. Comparing the analytical solutions with finite element method(FEM) results shows good coincidence. These numerical examples show that the present solutions are accurate. | Liu Shuhong Duan Shijie | 2014 | Chinese Journal of Aeronautics2014，27，4： | 5 |
| 6 | Bifurcation analysis for an SMIB power system with series capacitor compensation associated with sub-synchronous resonance显示文摘In this paper,an introduction to the bifurcation theory and its applicability to the study of sub-synchronous resonance (SSR) phenomenon in power system are presented. The continuation and bifurcation analysis software AUTO97 is adopted to investigate SSR for a single-machine-infinite-bus power system with series capacitor compensation. The investigation results show that SSR is the result of unstable limit cycle after bifurcation. When the system exhibits SSR, some complex periodical orbit bifurcations, such as torus bifurcation and periodical fold bifurcation, may happen with the variation of limit cycle. Furthermore, the initial operation condition may greatly influence the ultimate state of the system. The time-domain simulation is carried out to verify the effectiveness of the results obtained from the bifurcation analysis. | DUAN XianZhong WEN JinYu CHENG ShiJie | 2009 | Science China(Technological Sciences)2009，52，2： | 3 |
| 7 | Au/Ni12P5 core/shell single-crystal nanoparticles as oxygen evolution reaction catalyst显示文摘We have demonstrated the improved performance of oxygen evolution reactions(OER) using Au/nickel phosphide (Ni12P5) core/shell nanoparticles (NPs) underbasic conditions. NPs with a Ni12Ps shell and a Au core, both of which havewell-defined crystal structures, have been prepared using solution-based syntheticroutes. Compared with pure NiuP5 NPs and Au-Ni12P5 oligomer-like NPs, thecore/shell crystalline structure with Au shows an improved OER activity. Itaffords a current density of 10 mA/cm2 at a small overpotential of 0.34 V, in 1 MKOH aqueous solution at room temperature. This enhanced OER activity mayrelate to the strong structural and effective electronic coupling between thesingle-crystal core and the shell. | Yingying Xu Sibin Duan Haoyi Li Ming Yang Shijie Wang Xun Wang Rongming Wang | 2017 | Nano Research2017，10，9： | 2 |
| 8 | Skull metastasis revealing a papillary thyroid carcinoma显示文摘Although thyroid carcinoma is a relatively common form of malignancy,metastatic spread to the skull is rare.Here,we report a case of papillary thyroid carcinoma with frontal and parietal metastasis.A61-year-old Chinese woman presented with a one year history of a growing mass on the center of the frontal and parietal bone,initially thought to be meningioma.Biopsy of the skull base mass after intracalvarium excision,indicated a tumor of thyroid origin.One month later the patient underwent a total thyroidectomy.Pathological examination confirmed a diagnosis of papillary thyroid carcinoma with frontal and parietal bone metastasis.Based on this experience,the key to successful management of the skull metastasis of thyroid carcinoma is prompt diagnosis and appropriate treatment.Skull metastasis should be considered at the outset of the clinical course of papillary thyroid cancer.To facilitate this,patients should be meticulously investigated by a multidisciplinary team to improve quality of life. | Xi Li Ge Zhao Yong Zhang Kui Ding Hui Cao Dehua Yang Jian Zhang Zhiquan Duan Shijie Xin | 2013 | Chinese Journal of Cancer Research2013，25，5： | 2 |
| 9 | The influences of SE infection on layers' production performance,egg quality and blood biochemical indicators显示文摘Background:Salmonella enterica serovar Enteritidis(SE),as a major cause of foodbom illness,infects humans mainly through the egg.However,the symptom of laying hens usually is not typical and hard to diagnosis.In the present study,it is studied that the influences of SE infection on layers’ performance,egg quality and blood biochemical indicators.It will help us to improve the strategy to control SE infection in commercial layers.One hundred layers at 20 wk of age were divided into 2 groups,60 hens for experiment and others for control.The experiment group was fed with the dosage of 10~8 CFU SE per hen.The specific PCR was used to detect the deposition of SE.On the 8 d after SE infection,10 hens from the control group and 30 hens from the experimenta group were slaughtered to detect the SE colonization.The production performance,egg quality and blood biochemical indices were also analyzed.Results:The results showed that the colonization rate of SE was highest in caecum contents(55.17%) and lowest in vagina(17.24%).For the eggs the detection rate of SE was highest on the eggshell(80.00%) and lowest in yolk(18.81%).SE infection had no significant influence on production performance and egg qualities(P > 0.05).The difference of laying rate between the experimental and control groups was less than 0.30%,and both were approximately equal to 82.00%.The blood analysis showed that the aspartic aminotransferase(AST) and alanine aminotransferase(ALT) of experimental group was significantly higher than those of control group(P < 0.05).For experimental and control groups AST values were 236.22 U/l and 211.84 U/l respectively,and ALT values were32.19 U/l and 24.55 U/l.All of coefficients were less than 20%.The colonization of SE in organs increases the enzyme activities of AST and ALT in blood.Conclusions:SE in feed could invade the oviduct and infect the forming eggs.It significantly increased the concentration of ALT and AST in blood.However,SE infection was hard to be observed from the appearances of layer and egg.It might be a dangerous risk to human health. | Shijie Fan Jiangxia Zheng Zhongyi Duan Ning Yang Guiyun Xu | 2014 | Journal of Animal Science and Biotechnology2014，5，3： | 2 |
| 10 | SLC1A1-mediated cellular and mitochondrial influx of R-2-hydroxyglutarate in vascular endothelial cells promotes tumor angiogenesis in IDH1-mutant solid tumors显示文摘Muta nt isocitrate dehydrog en ase 1(mlDH1)drives tumorigenesis via produci ng on cometabolite R-2-hydroxyglutarate(R-2-HG)across various tumor types.However,mlDHl in hibitors appear only effective in hematological tumors.The therapeutic ben efit in solid tumors remains elusive,likely due to the complex tumor microenvironment.In this study,we discover that R-2-HG produced by IDH1-mutant tumor cells is preferentially imported into vascular endothelial cells and remodels mitochondrial respiration to promote tumor angiogenesis,conferring a therapeutic vulnerability in IDH1-mutant solid tumors.Mechanistically,SLC1 Alz a Na'-depe ndent glutamate tran sporter that is prefere ntially expressed in en dothelial cells,facilitates the in flux of R-2-HG from the tumor microenvironment into the endothelial cells as well as the intracellular trafficking of R-2-HG from cytoplasm to mitochondria.R-2-HG hijacks SLC1A1 to promote mitochondrial Na^(+)/Ca^(2+)exchange,which activates the mitochondrial respiratory chain and fuels vascular en dothelial cell migratio n in tumor an giogenesis.SLC1A1 deficiency in mice abolishes mlDHl-promoted tumor an giogenesis as well as the therapeutic benefit of mlDHl in hibitor in solid tumors.Moreover,we report that HH2301,a newly discovered mlDHl inhibitor,shows promising efficacy in treating IDH1-mutant cholangiocarcinoma in preclinical models.Together,we identify a new role of SLC1A1 as a gatekeeper of R-2-HG-mediated crosstalk between IDH1-mutant tumor cells and vascular en dothelial cells,and dem on strate the therapeutic potential of mlDHl in hibitors in treating IDH1-muta nt solid tumors via disrupting R-2-HG-promoted tumor angiogenesis. | Xiaomin Wang Ziqi Chen Jun Xu Shuai Tang Nan An Lei Jiang Yixiang Zhang Shaoying Zhang Qingli Zhang Yanyan Shen Shijie Chen Xiaojing Lan Ting Wang Linhui Zhai Siyuwei Cao Siqi Guo Yingluo Liu Aiwei Bi Yuehong Chen Xiameng Gai Yichen Duan Ying Zheng Yixian Fu Yize Li Liang Yuan Linjiang Tong Kun Mo Mingcheng Wang Shu-Hai Lin Minjia Tan Cheng Luo Yi Chen Jia Liu Qiansen Zhang Leping Li Min Huang | 2022 | Cell Research2022，32，7： | 2 |

| 12 | Variable elliptical vibrating screen: Particles kinematics and industrial application显示文摘Traditional vibrating screen usually adopts the linear centralized excitation mode,which causes the difficulty in particles loosening and low screening efficiency.The variable elliptical vibrating screen(VEVS)trajectory is regulated to adapt the material mass along the direction of the screen length,improving the particles distribution as well as the screening efficiency.In this work,a theoretical model was developed for analyzing the screen surface motion law during VEVS-based screening process.An equation was obtained to show the relationship between the horizontal amplitude and the vertical amplitude.The materials kinetic characteristics were studied by using high-speed camera during screening process.Compared with equal-amplitude screen(EAS),the material moving velocity was increased by 13.03%on the first half but decreased by 3.52% on the second half,and the total screening time was reduced by 9.42% by using VEVS.In addition,-6 mm screening test was carried out.At the length of VEVS equaled to 1.2 m,the screening efficiency and the total misplaced material content were 92.50% and 2.90%,respectively.However,the screening efficiency was 89.91% and the total misplaced material content was 3.76% during EAS-based screening process.Furthermore,when external moisture is 5.96%,the screening efficiency of VEVS could reach 86.95%.The 2 TKB50113 type VEVS with double-layered screen surface used in Huoshizui Coal Mine was 5.0 m in width and 11.3 m in length.The areas of single layer and double layer were 56.5 and 113 m~2,respectively.In industrial production,the processing capacity was 2500-3000 t/h and the screening efficiency was larger than 90%. | Chenlong Duan Jiale Yuan Miao Pan Tao Huang Haishen Jiang Yuemin Zhao Jinpeng Qiao Weinan Wang Shijie Yu Jiawang Lu | 2021 | International Journal of Mining Science and Technology2021，31，6： | 2 |

| 19 | A potential threat from biodegradable microplastics: mechanism of cadmium adsorption and desorption in the simulated gastrointestinal environment显示文摘It has been demonstrated that microplastics (MPs) can accumulate heavy metals from the environment and transfer them into organisms via the food chain. However, adsorption and desorption capacities for biodegradable MPs relative to those for conventional MPs remain poorly understood. In this study, cadmium (Cd(II)) adsorption and desorption characteristics of polylactic acid (PLA), a typical biodegradable MP, were investigated. Two conventional MPs, i.e., polypropylene (PP) and polyamide (PA) were used for comparison. The maximum Cd(II) adsorption capacities of the MPs studied in the adsorption experiments decreased in the order PA (0.96 ± 0.07 mg/g) > PLA (0.64 ± 0.04 mg/g) > PP (0.22 ± 0.03 mg/g). The Pseudo-second-order kinetic model and Freundlich isothermal model described the Cd(II) adsorption behaviors of PLA MPs well. X-ray photoelectron spectroscopy and two-dimensional Fourier transform infrared correlation spectroscopy analysis indicated that oxygen functional groups were the major and preferential binding sites of PLA MPs, which contributed to their high Cd(II) adsorption capacities. Simulated gastric and intestinal fluids both significantly enhanced the desorption capacities of the examined MPs. Notably, degradation of the PLA MPs during in vitro human digestion made the Cd(II) on the PLA MPs more bioaccessible (19% in the gastric phase and 62% in the intestinal phase) than Cd(II) on the PP and PA MPs. These results indicate the remarkable capacities of biodegradable MPs to accumulate Cd(II) and transfer it to the digestive system and show that biodegradable MPs might pose more severe threats to human health than conventional nonbiodegradable MPs. | Timing Jiang Xiang Wu Shushan Yuan Changfei Lai Shijie Bian Wenbo Yu Sha Liang Jingping Hu Liang Huang Huabo Duan Yafei Shi Jiakuan Yang | 2024 | Frontiers of Environmental Science & Engineering2024，18，2： | 0 |
| 20 | Comprehensive evaluation method of urban air quality statistics based on environmental monitoring data and its application显示文摘Air quality monitoring is effective for timely understanding of the current air quality status of a region or city.Currently,the huge volume of environmental monitoring data,which has reasonable real-time performance,provides strong support for in-depth analysis of air pollution characteristics and causes.However,in the era of big data,to meet current demands for fine management of the atmospheric environment,it is important to explore the characteristics and causes of air pollution from multiple aspects for comprehensive and scientific evaluation of air quality.This study reviewed and summarized air quality evaluation methods on the basis of environmental monitoring data statistics during the 13th Five-Year Plan period,and evaluated the level of air pollution in the Beijing-Tianjin-Hebei region and its surrounding areas(i.e.,the“2+26”region)during the period of the three-year action plan to fight air pollution.We suggest that air quality should be comprehensively,deeply,and scientifically evaluated from the aspects of air pollution characteristics,causes,and influences of meteorological conditions and anthropogenic emissions.It is also suggested that a threeyear moving average be introduced as one of the evaluation indexes of long-term change of pollutants.Additionally,both temporal and spatial differences should be considered when removing confounding meteorological factors. | Linglu Qu Fahe Chai Shijie Liu Jingchun Duan Fan Meng Miaomiao Cheng | 2023 | Journal of Environmental Sciences2023，，1： | 0 |
