| 2 | Charge Structure of a Summer Thunderstorm in North China:Simulation Using a Regional Atmospheric Model System显示文摘Electrification and simple discharge schemes are coupled into a 3D Regional Atmospheric Model System(RAMS) as microphysical parameterizations, in accordance with electrical experiment results. The dynamics, microphysics, and electrification components are fully integrated into the RAMS model, and the inductive and non-inductive electrification mechanisms are considered in the charging process. The results indicate that the thunderstorm mainly had a normal tripole charge structure.The simulated charge structure and lightning frequency are basically consistent with observations of the lightning radiation source distribution. The non-inductive charging mechanism contributed to the electrification during the whole lifetime of the thunderstorm, while the inductive electrification mechanism played a significant role in the development period and the mature stage when the electric field reached a large value. The charge structure in the convective region and the rearward region are analyzed, showing that the charge density in the convective region was double that in the rearward region. | LIU Dongxia QIE Xiushu PENG Liang LI Wanli | 2014 | Advances in Atmospheric Sciences2014，31，5： | 16 |
| 3 | Levels and distribution of brominated flame retardants in the soil of Harbin in China显示文摘This study reports the presence of brominated flame retardants in the topsoil in and around Harbin, a city in northeastern China. Samples of soil were collected from 17 locations in 2006, and the levels of 9 polybrominated diphenylethers (PBDEs 17, 28, 47, 66, 99, 100, 153, 154, and 183) ranged from 2.45 to 55.9 pg/g dry weight (dw) with a mean of 26.3 pg/g dw. These levels are very low comparing with those for some cities in Europe and USA. BDE 209 and hexabromocyclododecane were the two dominant congeners, with mean concentrations of 520 pg/g dw and 1750 pg/g dw, respectively. The concentrations of the total nine PBDE congeners clearly decreased from urban areas to background, but the compositions of individual congeners differed. Proportions of heavier congeners decreased while those of lighter congeners increased, along urban-rural-background transect, providing evidence for an urban fractionation effect. Correlation analysis indicated similar sources for PBDEs, hexabromocyclododecane, and 1,2-bis(2,4,6-tribromophenoxy)-ethane from urban areas but pentabromoethylbenzene was probably present due to long-range atmospheric transport. Principal component analysis was used to determine the characteristics of the relationships among these brominated flame retardants in the field. | WANG Xu REN Nanqi QI Hong MA Wanli LI Yifan | 2009 | Journal of Environmental Sciences2009，21，11： | 15 |
| 4 | Levels, distributions, and source identification of organochlorine pesticides in the topsoils in Northeastern China显示文摘Seventeen topsoil samples (9 urban, 4 suburban, 3 rural and 1 background) were collected in/around Harbin, a typical city in northeast of China, to measure concentration levels of organocholrine pesticides (OCPs) in topsoil of Northeastern China in 2006. Hexachlorohexanes (HCH), dichlorodiphenyltrichloroe thane (DDT), and hexachlorobenzene (HCB) were detected in soil samples with mean concentrations (in pg/g dry weight (dw)) of 7120, 5425, and 1039, respectively. The mean concentrations for other OCPs were very low, 4.8 pg/g dw for chlordane and 3.3 pg/g dw for endosulfan. Source identification analysis reveals that all OCPs found in soil samples were due to historical use of these chemicals or from other source regions through long- and short-range atmospheric transport. DDT was mainly used in the rural sites, whereas the sources of HCB, chlordane and endosulfan were mainly in the urban area. HCH was found almost equally in both urban and rural area. Soil concentrations of all detected OCPs, except HCHs, in and around Harbin were much lower than those in the southeast of China, which is expected since the use of these OCPs in the former was much lower than that in the latter, however higher HCH concentrations in and around Harbin than those found in most places of the Southeast China is not expected. It is suggested that high HCH concentration in soil of Northeast China was most likely due to long-range atmospheric transport (LRAT) from Southeast China and the cold condensation process. | WANG Xu REN Nanqi QI Hong MA Wanli LI Yifan | 2009 | Journal of Environmental Sciences2009，21，10： | 14 |
| 5 | Factors Associated with Thrombolysis Outcome in Ischemic Stroke Patients with Atrial Fibrillation显示文摘The outcome of early intravenous thrombolysis for ischemic stroke in patients with atrial fibrillation(AF)is worse than that without thrombosis. How to increase the efficacy of intravenous thrombolysis for AF-related ischemic stroke remains largely unknown. In this study, we investigated factors that influence the effect of intravenous thrombolysis in these patients. Our results showed that thrombolysis was independently associated with a favorable outcome(P \ 0.001) and did not influence the mortality of AF-related ischemic stroke, although it increased the risk of hemorrhage within 24 h after treatment. Risk factors for a poor outcome at admission were:heart failure(P = 0.045); high systolic pressure(P = 0.039); high blood glucose(P = 0.030); and a high National Institutes of Health Stroke Scale(NIHSS) score(P \ 0.001). Moreover, high systolic pressure at admission(P = 0.007), high blood glucose(P = 0.027), and a high NIHSS score(P \ 0.001) were independent risk factors for mortality at 3 months. Besides thrombolysis, a high NIHSS score(P = 0.006) and warfarin taken within 48 h before stroke onset(P = 0.032) were also independent risk factors for symptomatic hemorrhage within 24 h after treatment. Ischemic stroke patients with AF benefited from intravenous thrombolysis with recombinant tissue plasminogen activator within 4.5 h after stroke. | Qiuyun Zhao Xiaobo Li Wanli Dong Min Ye Yongjun Cao Meijuan Zhang Qiantao Cheng Junshan Zhou Guofang Chen Ming Yu Shanshan Hong Xiue Wei Bei Wang Guiyun Cui Peng Zhang Hong Ding Rongzhen Xu Yan Chen Yun Xu | 2016 | Neuroscience Bulletin2016，32，2： | 13 |
| 6 | TOLERANCE ANALYSIS OF A PLANETARY GEAR REDUCER UNDER CAD CIRCUMSTANCE显示文摘Tolerance analysis of a planetary reducer is conducted. By focusing the serially-arrangedparts in the central line and setting an appropriate dimension as a 'gap', worst-case tolerance analysismethod and statistical (RSS) tolerance analysis are used, and then a tolerance-analyzing tool CE/TOLis introduced. The acceptable value range of the 'gap' is from 1.5 mm to 3.5 mm. While worst-caseanalysis rejects the design, RSS accepts it by a more realistic result with the law of probability accounted.With the help of CE/TOL and CAD software Pro/E, all components’ dimensions and tolerances areassigned and modified, and more detailed and more comprehensible results are gives out. | Zhu Fumin Li Wanli Maropoulos P G | 2005 | Chinese Journal of Mechanical Engineering2005，18，3： | 11 |

| 8 | Clinical study using mesenchymal stem cells for the treatment of patients with severe COVID-19显示文摘The coronavirus disease 2019(COVID-19)caused by SARS-CoV-2 was identified in December 2019.The symptoms include fever,cough,dyspnea,early symptom of sputum,and acute respiratory distress syndrome(ARDS).Mesenchymal stem cell(MSC)therapy is the immediate treatment used for patients with severe cases of COVID-19.Herein,we describe two confirmed cases of COVID-19 in Wuhan to explore the role of MSC in the treatment of COVID-19.MSC transplantation increases the immune indicators(including CD4 and lymphocytes)and decreases the inflammation indicators(interleukin-6 and C-reactive protein).High-flow nasal cannula can be used as an initial support strategy for patients with ARDS.With MSC transplantation,the fracrion of inspired O2(Fi02)of the two patients gradually decreased while the oxygen saturation(Sa02)and partial pressure of oxygen(P02)improved.Additionally,the patients9 chest computed tomography showed that bilateral lung exudate lesions were adsorbed after MSC infusion.Results indicated that MSC transplantation provides clinical data on the treatment of COVID-19 and may serve as an alternative method for treating COVID-19,particularly in patients with ARDS. | Lingling Tang Yingan Jiang Mengfei Zhu Lijun Chen Xiaoyang Zhou Chenliang Zhou Peng Ye Xiaobei Chen Baohong Wang Zhenyu Xu Qiang Zhang Xiaowei Xu Hainv Gao Xiaojun Wu Dong Li Wanli Jiang Jingjing Qu Charlie Xiang Lanjuan Li | 2020 | Frontiers of Medicine2020，14，5： | 8 |
| 9 | Simulation of Quasi-Linear Mesoscale Convective Systems in Northern China:Lightning Activities and Storm Structure显示文摘Two intense quasi-linear mesoscale convective systems(QLMCSs) in northern China were simulated using the WRF(Weather Research and Forecasting) model and the 3D-Var(three-dimensional variational) analysis system of the ARPS(Advanced Regional Prediction System) model.A new method in which the lightning density is calculated using both the precipitation and non-precipitation ice mass was developed to reveal the relationship between the lightning activities and QLMCS structures.Results indicate that,compared with calculating the results using two previous methods,the lightning density calculated using the new method presented in this study is in better accordance with observations.Based on the calculated lightning densities using the new method,it was found that most lightning activity was initiated on the right side and at the front of the QLMCSs,where the surface wind field converged intensely.The CAPE was much stronger ahead of the southeastward progressing QLMCS than to the back it,and their lightning events mainly occurred in regions with a large gradient of CAPE.Comparisons between lightning and non-lightning regions indicated that lightning regions featured more intense ascending motion than non-lightning regions;the vertical ranges of maximum reflectivity between lightning and non-lightning regions were very different;and the ice mixing ratio featured no significant differences between the lightning and non-lightning regions. | Wanli LI Xiushu QIE Shenming FU Debin SU Yonghai SHEN | 2016 | Advances in Atmospheric Sciences2016，33，1： | 7 |

| 11 | Effects of biochar on water movement characteristics in sandy soil under drip irrigation显示文摘Biochar addition can improve the physical and hydraulic characteristics of sandy soil.This study investigated the effects of biochar on water holding capacity and water movement in sandy soil under drip irrigation.By indoor simulation experiments,the effects of biochar application at five levels(0%,1%,2%,4%and 6%)on the soil water retention curve,infiltration characteristics of drip irrigation and water distribution were tested and analyzed.The results showed that biochar addition rate was positively correlated with water holding capacity of sandy soil and soil available water.Within the same infiltration time,with an increasing amount of added biochar,the diffusion distance of the horizontal wetting front(HWF)tended to decrease,while the infiltration distance of vertical wetting front(VWF)initially declined and then rose.The features of wetted bodies changed from'broad-shallow'to'narrow-deep'type.The relationship between the transport distances of HWF and VWF and the infiltration time was described by a power function.At the same distance from the point source,the larger the amount of added biochar,the higher the soil water content.Biochar had a great influence on the water content of the layer with biochar(0–200 mm)and had some effects at 200–250 mm without biochar;but it had less influence on the soil water content deeper than 250 mm.For the application rate of biochar of 4%,most water was retained within 0–250 mm soil layer.However,when biochar application amount was high(6%),it would be helpful for water infiltration.During the improvement of sandy soil,biochar application rate of 4%in the plow layer had the best effect. | PU Shenghai LI Guangyong TANG Guangmu ZHANG Yunshu XU Wanli LIPan FENG Guangping DING Feng | 2019 | Journal of Arid Land2019，11，5： | 6 |
| 12 | Molecular Cytogenetic Characterization of a Wheat-Leymus mollis 3D(3Ns) Substitution Line with Resistance to Leaf Rust显示文摘Leymus mollis(Trin.)Pilger(NsNsXmXm,2n?28),a wild relative of common wheat,possesses many potentially valuable traits that could be transferred to common wheat during breeding programs.In this study,the karyotypic constitution of a wheat e L.mollis 3D(3Ns#1)disomic substitution line isolated from the F5progeny of octoploid Tritileymus M842-16 Triticum durum cv.D4286,which was designated as 10DM57,was determined using genomic in situ hybridization(GISH),fluorescent in situ hybridization(FISH),SSR markers,and ESTSTS markers.Screening of mitosis and meiosis showed that 10DM57 had a chromosome karyotype of 2n?42?21II.GISH indicated that10DM57 was a line with 40 chromosomes from wheat and two of the Ns chromosomes from L.mollis,which formed a ring bivalent in pollen mother cells at metaphase I.FISH analysis showed that the chromosome 3D may be replaced by 3Ns#1 in 10DM57.DNA markers,including SSR and EST-STS primers,showed that the pair of wheat chromosome 3D in 10DM57 was substituted by the pair of chromosome 3Ns#1from L.mollis.Evaluation of the agronomic traits showed that,compared with its common wheat relative 7182,10DM57 was resistant to leaf rust while the spike length and number of spikes per plant were improved significantly,which correlated with a higher wheat yield.The new germplasm,10DM57,could be exploited as an intermediate material in wheat genetic and breeding programs. | Yuhui Pang Xinhong Chen Jixin Zhao Wanli Du Xueni Cheng Jun Wu Yanli Li Liangming Wang Jing Wang Qunhui Yang | 2014 | Journal of Genetics and Genomics2014，41，4： | 6 |

| 14 | A Volumetric Model for Evaluating Tight Sandstone Gas Reserves in the Permian Sulige Gas Field,Ordos Basin,Central China显示文摘To accurately measure and evaluate reserves is critical for ensuring successful production of unconventional oil and gas. This work proposes a volumetric model to evaluate the tight sandstone gas reserves of the Permian Sulige gas field in the Ordos Basin. The reserves can be determined by four major parameters of reservoir cutoffs, net pay, gas-bearing area and compression factor Z, which are controlled by reservoir characteristics and sedimentation. Well logging, seismic analysis, core analysis and gas testing, as well as thin section identification and SEM analysis were used to analyze the pore evolution and pore-throat structure. The porosity and permeability cutoffs are determined by distribution function curve,empirical statistics and intersection plot. Net pay and gas-bearing area are determined based on the cutoffs, gas testing and sand body distribution, and the compression factor Z is obtained by gas component. The results demonstrate that the reservoir in the Sulige gas field is characterized by ultralow porosity and permeability, and the cutoffs of porosity and permeability are 5% and 0.15×10^(–3) μm^2, respectively. The net pay and gas-bearing area are mainly affected by the sedimentary facies, sand body types and distribution. The gas component is dominated by methane which accounts for more than 90%, and the compression factor Z of H_8(P_2h_8) and S_1(P_1s_1) are 0.98 and 0.985, respectively. The distributary channels stacked and overlapped, forming a wide and thick sand body with good developed intergranular pores and intercrystalline pores. The upper part of channel sand with good porosity and permeability can be sweet spot for gas exploration. The complete set of calculation systems proposed for tight gas reserve calculation has proved to be effective based on application and feedback. This model provides a new concept and consideration for reserve prediction and calculation in other areas. | CUI Mingming FAN Aiping WANG Zongxiu GAO Wanli LI Jinbu LI Yijun | 2019 | Acta Geologica Sinica(English Edition)2019，93，2： | 4 |
| 15 | Influences of Film Thickness on the Electrical Properties of TaN_x Thin Films Deposited by Reactive DC Magnetron Sputtering显示文摘TaNx thin films were deposited on commercial polished Al2O3 ceramic substrates by reactive dc magnetron sputtering. The influences of the film thickness on the electrical properties of the samples were examined in detail. It is found that the film thickness does not influence the phase structures of the TaNx thin films. The sheet resistances of the samples shift from 173 Ω/sq. to 7.5 Ω/sq. with the film thickness shifting from 30 nm to 280 nm. With the increase of the film thickness from 30 nm to 280 nm, the temperature coefficient of resistance (TCR) of the samples shifts from negative value to positive value. When the film thickness is about 100 nm, TaNx thin films exhibits a near-zero TCR value (approximately -15×10-6/℃). This fact implies that TaNx thin films with a null TCR can be obtained by adjusting the film thickness. The variation in the electrical properties of the TaNx thin films with the film thickness can be qualitatively explained by the parallel connection of surface layer with high resistivity and negative TCR and TaNx layer with low resistivity and positive TCR. | Hongchuan Jiang Chaojie Wang Wanli Zhang Xu Si Yanrong Li | 2010 | Journal of Materials Science & Technology2010，26，7： | 3 |
| 16 | A family net of giant pandas in the Tangjiahe Natural Reserve:Assessment of current individual migration显示文摘In the present study, formalin-fixed feces, oli-gonucleotide fingerprinting and SRY-gene based sexing were used to construct a family net for giant pandas in the Tang-jiahe Natural Reserve and to assess contemporary gene flow (migration) in this population. A total of 124 fecal samples were attributed to 37 individuals (22 females and 15 males) that were then analyzed for family relationships. Based on DNA fingerprints, the deduced family net revealed the fol-lowing facts: (i) First-order relatives possessed similarities from 50% to 90%, and similarities between unrelated indi-viduals or distant relatives were as high as 77%, indicating that the Tangjiahe pandas are characterized by high genetic similarity; (ii) 15 matings were identified and 5 ones oc-curred between close relatives, implying that there is poten-tial for inbreeding to impact the pandas; (iii) four mating pairs and 5 offspring presented long distance migrations, demonstrating the intra-reserve habitat is continuous; (iv) four pairs of full sibs (also female-male dyads) dispersed short distance and all of them gave birth to highly inbred offspring, reflecting long distance migration is vital for in-breeding avoidance; (v) 17 adult individuals dispersed short or moderate distance and formed three clusters on the land-scape, indicating that it is necessary to find out whether there is a negative factor impacting the pandas. | WAN Qiuhong FANG Shengguo LI Jianguo ZHANG Liming OU Weifu XIAN Fanghai CHEN Wanli | 2005 | Chinese Science Bulletin2005，50，17： | 3 |
| 17 | Late Cretaceous Transpressional Fault System: A Case Study of the Yishu Fault Belt, Shandong Province, Eastern China显示文摘On the basis of field observations of the structures of three profiles from the Linshu region, deformation characteristics and the tectonic background of the Yishu fault belt in the Late Cretaceous–Early Cenozoic have been discussed in detail.Three structural profiles, whose deformations consist mainly of earlier transpressional faults and later normal faults, were developed for the Mengtuan Formation of the Lower Cretaceous Dasheng Group.Typical positive flower structures, duplex structures, and break-through faults were found in these profiles.On the basis of analyses of the structural deformation and previous geochronological studies, it was concluded that the earlier transpressional faults of the profiles were triggered by the sinistral transpression of the Yishu fault belt in the Late Cretaceous–Early Paleogene, and that the later normal faults, formed during the Late Paleogene–Neogene extension, truncated the earlier transpressional faults.With consideration of the tectonic evolution of the Tan-Lu fault belt and the different drift directions of the Pacific plate since the Cretaceous, we suggest that the major tectonic events of the Late Cretaceous–Neogene in eastern China were mainly controlled by the subduction of the Pacific plate. | LI Chunlin WANG Zongxiu WU Qingzi LIU Yongqing GAO Wanli TAN Yuanlong KUANG Hongwei LI Huijun | 2015 | Acta Geologica Sinica(English Edition)2015，89，5： | 3 |
| 18 | 大肠癌筛查的成本测算及成本控制(英文)显示文摘Objective:The aim of our study was to estimate the cost of colorectal cancer screening and to provide evidence for the cost control of colorectal cancer screening among general population in rural area of China.Methods:We determined the net cost for colorectal cancer mass-screening in Jiashan County,and evaluated the cost-benefit and cost effectiveness.Results:The compliance rate of primary screening and intensive screening were 84.6% and 78.7%,respectively.In primary screening,the average cost for each individual was 27.2 yuan,and the average cost for identifying one high-risk individual was 180.5 yuan.The mean cost to diagnose one colorectal cancer patient was 42963.3 yuan.As for identification of adenoma,the average cost for each case was 4384.0 yuan.Based on the calculation,the average cost of reducing one colorectal cancer patient was 12768 yuan by conducting the mass-screening protocol.Conclusion:It was beneficial to do the cost-benefit analysis of colorectal cancer screening in area of high incidence.Based on the results of cost-benefit analysis,more efforts should be made to reduce the cost and to improve the efficiency of the colorectal cancer screening. | Xinyuan Ma Qilong Li Wanli Ma | 2012 | The Chinese-German Journal of Clinical Oncology2012，11，2： | 2 |
| 19 | Quality of information disclosure, property rights, and bank loans: A bank heterogeneity perspective显示文摘Using the context of the financial reform and the development of the non-state sector in China in the past decade, we examine the roles that the quality of information disclosure and property rights play in the allocation of different types of bank credit. We find that foreign banks and policy banks exercise ‘‘financial discrimination,' and that local commercial banks, large state- owned commercial banks, national joint-stock banks, local city commercial banks, and rural commercial banks not only exercise financial discrimination but also provide significant ‘‘financial support' to non-state-owned enterprises by providing more lending opportunities and larger loans. However, when enterprises commit information disclosure violations, the local commercial banks, national joint-stock banks, local city commercial banks, and rural commercial banks reverse their credit decisions and begin to exercise financial dis- crimination against non-state-owned enterprises. At the same time, large stateowned commercial banks continue to provide financial support to non-state-owned enterprises. We also find that the quality of the information disclosed by enterprises has a moderating effect rather than an intermediary effect on the relationship between property rights and bank loans. Overall, the results of this paper shine new light on the market-oriented reform of the banking industry, and provide new empirical evidence for the presence of financial discrimination in the supply of bank credit. Our findings also have practical implications for solving the financing difficulties of non-state-owned enterprises. | Xichan Chen Wanli Li Shiyang Hu Xing Liu | 2019 | China Journal of Accounting Research2019，，1： | 2 |
| 20 | Applications of nanogenerators for biomedical engineering and healthcare systems显示文摘The dream of human beings for long living has stimulated the rapid development of biomedical and healthcare equipment.However,conventional biomedical and healthcare devices have shortcomings such as short service life,large equipment size,and high potential safety hazards.Indeed,the power supply for conventional implantable device remains predominantly batteries.The emerging nanogenerators,which harvest micro/nanomechanical energy and thermal energy from human beings and convert into electrical energy,provide an ideal solution for self-powering of biomedical devices.The combination of nanogenerators and biomedicine has been accelerating the development of self-powered biomedical equipment.This article first introduces the operating principle of nanogenerators and then reviews the progress of nanogenerators in biomedical applications,including power supply,smart sensing,and effective treatment.Besides,the microbial disinfection and biodegradation performances of nanogenerators have been updated.Next,the protection devices have been discussed such as face mask with air filtering function together with real-time monitoring of human health from the respiration and heat emission.Besides,the nanogenerator devices have been categorized by the types of mechanical energy from human beings,such as the body movement,tissue and organ activities,energy from chemical reactions,and gravitational potential energy.Eventually,the challenges and future opportunities in the applications of nanogenerators are delivered in the conclusive remarks. | Wanli Wang Jinbo Pang Jie Su Fujiang Li Qiang Li Xiaoxiong Wang Jingang Wang Bergoi Ibarlucea Xiaoyan Liu Yufen Li Weijia Zhou Kai Wang Qingfang Han Lei Liu Ruohan Zang Mark HRümmeli Yang Li Hong Liu Han Hu Gianaurelio Cuniberti | 2022 | InfoMat2022，4，2： | 2 |
