| 1 | Urban Three-dimensional Expansion and Its Driving Forces——A Case Study of Shanghai,China显示文摘Urban expansion is a phenomenon of urban space increase,and an important measuring index of the process of urbanization.Taking Shanghai as an example,the changes of urban average height and built-up area were studied to represent city's vertical and horizontal increases respectively,and statistical methods were used to analyze the driving forces of urban expansion.The research drew following conclusions:1) The urban expansion process of Shanghai from 1985 to 2006 had a clear periodic feature,and could be divided into three stages:vertical expansion in dominance,coordinated vertical and horizontal expansion,and horizontal expansion in dominance.2) The average height and quantity of buildings in core city were significantly bigger than those in suburbs,but the changing speed of the latter was faster.And 3) urbanization process was the major driving force for the city's horizontal expansion,while industrial structure improvement was the key driving factor for the vertical expansion.Those two driving forces were simultaneously affected by city's political factors. | SHI Longyu SHAO Guofan CUI Shenghui LI Xuanqi LIN Tao YIN Kai ZHAO Jingzhu | 2009 | Chinese Geographical Science2009，19，4： | 20 |
| 2 | Modelling operation parameters of UAV on spray effects at different growth stages of corns显示文摘Currently,unmanned aerial vehicles(UAVs)were widely applied to spray for pest and disease control.However,spray effect can be further improved by setting operation parameters more reasonably and scientifically.Therefore,this study attempts to derive the relationship between operation parameters and spray effect.Different growth stages were distinguished by various corn heights.A six-rotor UAV was operated at different heights and velocities to test pesticides spray effects for corns at different growth stages.Different plant canopy coverage rate and penetrating coefficients were obtained,according to which,the effects on droplet deposition rate caused by different UAVs’operation parameters were analyzed.Droplet penetrating coefficients were applied as indexes to evaluate and select UAVs operation parameters for corns at different growth stages respectively.Mathematical models of droplet penetrating coefficients with UAVs operation parameters were established for corns at all growth stages.The determination coefficients(R2)of all models were greater than 0.90 and average relative errors were within 20%,which asserted high forecasting accuracy of droplet penetrating rate.With the help of the models,parameters like operating height away from the bottom of corns and UAVs velocities were further analyzed,which guided the optimization of parameter settings and selection of spray methods for corns at different growth stages. | Zheng Yongjun Yang Shenghui Zhao Chunjiang Chen Liping Yubin Lan Tan Yu | 2017 | International Journal of Agricultural and Biological Engineering2017，10，3： | 13 |

| 4 | Carbon isotope composition and correlation across the Cambrian-Ordovician boundary in Kalpin Region of the Tarim Basin, China显示文摘Biostratigraphically constrained sequences at the Wushi Yingshan and Kalpin Cement Plant sections (Kalpin Region; Tarim Basin) were densely sampled for geochemical studies. Carbonates across the Cambrian-Ordovician boundary of both sections mainly record negative carbon isotope values. Stable isotope curves show four negative and four positive excursions appearing alternately at the Wushi Yingshan section and five negative alternating with five positive excursions at the Kalpin Cement Plant section. The carbon isotope logs of these two sections are correlated with the international Cambrian-Ordovician boundary key sections: (1) Dayangcha section in China, (2) Green Point section in Canada, (3) Black mountain section in Australia and (4) Lowson Cove section in USA. These correlations suggest that the Cambrian-Ordovician boundary of the Wushi Yingshan section and the Kalpin Cement Plant section can be placed within a particular horizon that also corresponds to the observed biostratigraphic units. | JING XiuChun DENG ShengHui ZHAO ZongJu LU YuanZheng ZHANG ShiBen | 2008 | Science China Earth Sciences2008，51，9： | 8 |
| 5 | A New Carbon and Oxygen Balance Model Based on Ecological Service of Urban Vegetation显示文摘The application of human induced oxygen consumption and carbon emission theory in urban region was summed up and on this base a new model of urban carbon and oxygen balance (UCOB) was constructed by calculating the carbon and oxygen fluxes. The purpose was to highlight the role of vegetation in urban ecosystems and evaluate the effects of various human activities on urban annual oxygen consumption and carbon emission. Hopefully,the model would be helpful in theory to keep the regional balance of carbon and oxygen,and provide guidance and support for urban vegetation planning in the future. To test the UCOB model,the Jimei District of Xiamen City,Fujian Province,China,a very typical urban region,was selected as a case study. The results turn out that Jimei′s vegetation service in oxygen emission and carbon sequestration could not meet the demand of the urban population,and more than 31.49 times of vegetation area should be added to meet the whole oxygen consumption in Jimei while 9.60 times of vegetation area are needed to meet the carbon sequestration targets. The results show that the new UCOB model is of a great potential to be applied to quantitative planning of urban vegetation and regional eco-compensation mechanisms. | YIN Kai ZHAO Qianjun LI Xuanqi CUI Shenghui HUA Lizhong LIN Tao | 2010 | Chinese Geographical Science2010，20，2： | 6 |
| 6 | Characteristics of Vibration and Sound Radiation of Metro Resilient Wheel显示文摘Resilient wheels are extensively used in urban rail transit, especially for tramway systems, owing to its advantages in noise reduction. A new type of resilient wheel for a metro is designed, and its characteristics of vibration and sound radiation, including the rolling noise of a resilient single wheel coupled with a track, are studied in this paper. A two-step research is presented. Firstly, laboratory experiments were conducted to obtain the vibration response of the designed resilient wheel under the radial excitation on its tread. Secondly, the rolling noise model of the resilient wheel coupled with a slab track used in a metro line is developed. The wheel model is based on the 3 D finite elementand boundary element methods and verified by using the experimental results obtained from the laboratory. The track vibration model is based on the wavenumber finite element method, and the track sound radiation is calculatedby using an e cient frequency-domain Rayleigh method. The interaction of the resilient wheel and the slab track is analyzed considering the measured wheel/rail roughness of the metro. The contribution of the resilient wheel to the reduction of wheel/rail system noise is analyzed. The results show that the resilient wheel can e ectively reduce the wheel/rail rolling noise by approximately 2 dB(A) to 3 dB(A), mainly because the radiated noise by the rail is reduced. In addition, the elastic modulus of the rubber has an important influence on the noise reduction of resilient wheels. | Xin Zhou Jian Han Yue Zhao Bing Wu Gong Cheng Shenghui Xu Xuesong Jin | 2019 | Chinese Journal of Mechanical Engineering2019，32，4： | 5 |
| 7 | Loss of Wip1 aggravates brain injury after ischaemia/reperfusion by overactivating microglia显示文摘Background and purpose The inflammatory response mediated by microglia/macrophages is closely related to cerebral ischaemia/reperfusion injury.Wild-type p53-induced protein phosphatase 1(Wip1),a serine/threonine phosphatase,is expressed in various tissues.A growing number of reports have suggested that Wip1 is a negative regulator of inflammation in peripheral tissue;however,its role in the central nervous system(CNS)remains unclear.This study aimed to clarify whether Wip1 can inhibit CNS inflammation by regulating microglia/macrophage functions after ischaemic injury.Methods A model of middle cerebral artery occlusion and reperfusion was established in mice.CNS inflammation was simulated by lipopolysaccharide treatment of primary microglia.Laser speckle imaging was used to monitor regional cerebral blood flow.Behavioural outcomes were assessed with a TreadScan gait analysis system.TTC staining was used to evaluate the infarct volume,and western blotting and immunofluorescence staining were applied to detect the phenotypical transformation of microglia.ELISA was performed to detect the levels of inflammatory factors.Results Wip1 expression was increased after ischaemia/reperfusion.Wip1-knockout(KO)mice displayed more severe brain injury than wild-type mice,as indicated by aggravated motor dysfunction,greater brain infarct volumes and higher expression of inflammatory cytokines(interleukin-6 and tumour necrosis factor alpha)in the brain.We also found that Wip1 depletion increased microglial/macrophage activation in both in vitro and in vivo models,which all showed activation of microglia/macrophages.Lentivirus-Ppm1d reversed the injury induced by Wip1-KO.Conclusions Our results suggest that Wip1 may inhibit neuroinflammation by inhibiting microglial/macrophage activation after brain ischaemia/reperfusion injury. | Feng Yan Xiang Cheng Ming Zhao Shenghui Gong Ying Han Liping Ding Di Wu Yumin Luo Wei Zuo Lingling Zhu Ming Fan Xunming Ji | 2021 | Stroke & Vascular Neurology2021，6，3： | 4 |
| 8 | Improvement in quality of life in depressed patients following verum acupuncture or electroacupuncture plus paroxetine:A randomized controlled study of 157 cases显示文摘Depressed patients with scores of 17 or more on the 17 items of the Hamilton Depression Rating Scale were treated with the antidepressant drug paroxetine. They also underwent verum acupuncture or electroacupuncture at Baihui (GV20) and Yintang (GV29). The World Health Organization Quality of Life Scale Brief Version showed a significant increase in the total scores of patients who underwent verum acupuncture and electroacupuncture for 6 weeks compared with those who were given paroxetine only; significantly increased physical domain and social relationship scores in verum acupuncture patients compared with paroxetine only; and significantly elevated psychological domain scores with electroacupuncture compared with paroxetine only. These results indicate that both verum acupuncture and electroacupuncture can improve quality of life in depressed patients undergoing paroxetine treatment. | Shenghui Ma Shanshan Qu Yong Huang Junqi Chen Renyong Lin Chongqi Wang Ganlong Li Canghuan Zhao Shenchang Guo Zhangjin Zhang | 2012 | Neural Regeneration Research2012，7，27： | 3 |
| 9 | Animal exercise studies in cardiovascular research:Current knowledge and optimal design--A position paper of the Committee on Cardiac Rehabilitation,Chinese Medical Doctors’Association显示文摘Growing evidence has demonstrated exercise as an effective way to promote cardiovascular health and protect against cardiovascular diseases However,the underlying mechanisms of the beneficial effects of exercise have yet to be elucidated.Animal exercise studies are widely used to investigate the key mechanisms of exercise-induced cardiovascular protection.However,standardized procedures and well-established evaluation indicators for animal exercise models are needed to guide researchers in carrying out effective,high-quality animal studies using exercise to prevent and treat cardiovascular diseases.In our review,we present the commonly used animal exercise models in cardiovascular research and propose a set of standard procedures for exercise training,emphasizing the appropriate measurements and analysis in these chronic exercise models.We also provide recommendations for optimal design of animal exercise studies in cardiovascular research,including the choice of exercise models,control of exercise protocols,exercise at different stages of disease,and other considerations,such as age,sex,and genetic background.We hope that this position paper will promote basic research on exercise-induced cardiovascular protection and pave the way for successful translation of exercise studies from bench to bedside in the prevention and treatment of cardiovascular diseases. | Yihua Bei Lei Wang Rongjing Ding Lin Che Zhiqing Fan Wei Gao Qi Liang Shenghui Lin Suixin Liu Xiao Lu Yuqin Shen Guifu Wu Jian Yang Guolin Zhang Wei Zhao Lan Guo Junjie Xiao | 2021 | Journal of Sport and Health Science2021，10，6： | 2 |
| 10 | Subdivision and age of the Yanchang Formation and the Middle/Upper Triassic boundary in Ordos Basin, North China显示文摘The Yanchang Formation is extensively developed in the Ordos Basin and its surrounding regions. As one of the best terrestrial Triassic sequences in China and the major oil-gas bearing formations in the Ordos Basin, its age determination and stratigraphic assignment are important in geological survey and oil-gas exploration. It had been attributed to the Late Triassic and regarded as the typical representative of the Upper Triassic in northern China for a long time, although some scholars had already proposed that the lower part of this formation should be of the Middle Triassic age in the mid-late 20 th century. In this paper, we suggest that the lower and middle parts of the Yanchang Formation should be of the Ladinian and the bottom possibly belongs to the late Anisian of the Middle Triassic, mainly based on new fossils found in it and high resolution radiometric dating results. The main source rocks, namely the oil shales and mudstones of the Chang-7, are of the Ladinian Age. The upper part of the Yanchang Formation, namely the Chang-6 and the above parts, belongs to the Late Triassic. The uppermost of the Triassic is missed in most parts of the Ordos Basin. The Middle-Upper Triassic Series boundary lies in the Yanchang Formation, equivalent to the boundary between Chang-7 and Chang-6. The Ladinian is an important palaeoenvironmental turning point in the Ordos Basin. Palaeoenvironmental changes in the basin are coincidence with that of the Sichuan Basin and the main tectonic movement of the Qinling Mountains. It indicates that tectonic activities of the Qinling Mountains are related to the big palaeoenvironmental changes in both the Ordos and Sichuan Basins, which are caused by the same structural dynamic system during the Ladinian. | Shenghui DENG Yuanzheng LU Zhong LUO Ru FAN Xin LI Yi ZHAO Xueying MA Rukai ZHU Jingwei CUI | 2018 | Science China Earth Sciences2018，61，10： | 2 |
| 11 | Self-supported hierarchical porous Li_(4)Ti_(5)O_(12)/carbon arrays for boosted lithium ion storage显示文摘The development of fast rechargeable lithium ion batteries(LIBs)is highly dependent on the innovation of advanced high-power electrode materials.In this work,for the first time,we report a sacrificial NiO arrays template method for controllable synthesis of self-supported hierarchical porous Li_(4)Ti_(5)O_(12)/C(LTO/C)nanoflakes arrays,for use as fast rechargeable anodes for LIBs.The ultrathin(2-3 nm)carbon layer was uniformly coated on the LTO forming arrays architecture.The hierarchical porous LTO/C nanoflakes consisted of primary cross-linked nanoparticles of 50-100 nm and showed large porosity.Because of the enhanced electrical conductivity and accelerated ion transfer channels,the well-designed binderfree porous LTO/C nanoflakes arrays exhibited notable high-rate lithium ion storage performance with smaller polarization,better electrochemical reactivity,higher specific capacity(157 mAh g^(-1) at the current density of 20C)and improved long-term cycling life(96.2% after 6000 cycles at 20C),superior to the unmodified porous LTO arrays counterpart(126 mAh g^(-1) at 20C and 88.0%after 6000 cycles at 20C).Our work provides a new template for the construction of high-performance high-rate electrodes for electrochemical energy storage. | Jun Liu Aixiang Wei Guoxiang Pan Shenghui Shen Zhiming Xiao Yu Zhao Xinhui Xia | 2021 | Journal of Energy Chemistry2021，30，3： | 2 |
| 12 | A novel detection method of spray droplet distribution based on LIDARs显示文摘During the process of plant protection in agriculture,the distribution and deposition of droplets or fog fields could directly influence the effectiveness and efficiency of spray.The traditional method of measurement of the distribution of droplets mainly used water sensitive papers,glass containers or flour to collect data and inverse results,while a new method of measurement based on the principle of reflection of LIDAR was presented.Droplets were the major targets of the study,and four important algorithms were primarily developed,including the recognition and extraction of targets,the superposition in time-domain,the calculation of effective ranges of distribution,and the development of 3D distribution models.Combined with these algorithms,in order to eliminate the environmental noise,the methods of Fuzzy Environment Matching and Secondary Filter were created and utilized.Meanwhile,the statistics was used for analysis of the duration of scanning as well as computation of the distribution,with enough datasets but the minimum length of time.The results of the experiments showed that the relative error of measurement was less than 7%and Relative Standard Deviation was less than 16%,compared with the values of manual measurement.Furthermore,the 3D models were accurate and clarified in the wind-tunnel experiment.The completed system based on this method could adapt to the requirements of both indoor and outdoor detection.Besides,it is capable of the quantized detection of droplet distribution,providing an effective way of tests for spray technique,especially for the research of the application of plant protection by UAVs. | Zheng Yongjun Yang Shenghui Yubin Lan Clint Hoffmann Zhao Chunjiang Chen Liping Liu Xingxing Tan Yu | 2017 | International Journal of Agricultural and Biological Engineering2017，10，4： | 2 |
| 13 | Tumor neoantigens: Novel strategies for application of cancer immunotherapy显示文摘Neoantigen-targeted immunotherapy is a rapidly advancing field that holds great promise for treating cancer.The recognition of antigens by immune cells is a crucial step in tumor-specific killing,and neoantigens generated by mutations in cancer cells possess high immunogenicity and are selectively expressed in tumor cells,making them an attractive therapeutic target.Currently,neoantigens find utility in various domains,primarily in the realm of neoantigen vaccines such as DC vaccines,nucleic acid vaccines,and synthetic long peptide vaccines.Additionally,they hold promise in adoptive cell therapy,encompassing tumor-infiltrating cells,T cell receptors,and chimeric antigen receptors which are expressed by genetically modified T cells.In this review,we summarized recent progress in the clinical use of tumor vaccines and adoptive cell therapy targeting neoantigens,discussed the potential of neoantigen burden as an immune checkpoint in clinical settings.With the aid of state-of-the-art sequencing and bioinformatics technologies,together with significant advancements in artificial intelligence,we anticipated that neoantigens will be fully exploited for personalized tumor immunotherapy,from screening to clinical application. | HANYANG GUAN YUE WU LU LI YABING YANG SHENGHUI QIU ZHAN ZHAO XIAODONG CHU JIASHUAI HE ZUYANG CHEN YIRAN ZHANG HUI DING JINGHUA PAN YUNLONG PAN | 2023 | Oncology Research2023，31，4： | 1 |

| 16 | From VIB‑to VB‑Group Transition Metal Disulfides:Structure Engineering Modulation for Superior Electromagnetic Wave Absorption显示文摘The laminated transition metal disulfides(TMDs),which are well known as typical two-dimensional(2D)semiconductive materials,possess a unique layered structure,leading to their wide-spread applications in various fields,such as catalysis,energy storage,sensing,etc.In recent years,a lot of research work on TMDs based functional materials in the fields of electromagnetic wave absorption(EMA)has been carried out.Therefore,it is of great significance to elaborate the influence of TMDs on EMA in time to speed up the application.In this review,recent advances in the development of electromagnetic wave(EMW)absorbers based on TMDs,ranging from the VIB group to the VB group are summarized.Their compositions,microstructures,electronic properties,and synthesis methods are presented in detail.Particularly,the modulation of structure engineering from the aspects of heterostructures,defects,morphologies and phases are systematically summarized,focusing on optimizing impedance matching and increasing dielectric and magnetic losses in the EMA materials with tunable EMW absorption performance.Milestones as well as the challenges are also identified to guide the design of new TMDs based dielectric EMA materials with high performance. | Junye Cheng Yongheng Jin Jinghan Zhao Qi Jing Bailong Gu Jialiang Wei Shenghui Yi Mingming Li Wanli Nie Qinghua Qin Deqing Zhang Guangping Zheng Renchao Che | 2024 | Nano-Micro Letters2024，16，2： | 0 |
| 17 | PIM2 regulates stemness through phosphorylation of 4E-BP1显示文摘Embryonic stem cells(ESCs) can undergo unlimited self-renewal and maintain pluripotency to differentiate into any cell type of the three germ layers. Extensive studies have shown ESC identity is regulated by transcription factors, epigenetic regulators and multiple signal transduction pathways. However, the kinase regulation of pluripotency is not well understood. Here we show that the serine/threonine kinase PIM2, which is highly expressed in ESCs but not in somatic cells, functions as a crucial stemness regulator in ESCs. Knockout of Pim2 inhibits the self-renewal and differentiation capability of ESCs. Mechanistic studies identified that PIM2 can directly phosphorylate 4E-BP1, leading to release of e IF4E which facilitates the translation of pluripotent genes in ESCs. Our study highlights a novel kinase cascade pathway for ESC identity maintenance. | Hongyan Sun Jiani Cao Lin Zhao Shaohua Zhu Shenghui Chen Yaqiong Li Bin Zhao Tongbiao Zhao | 2017 | Science Bulletin2017，62，10： | 0 |
| 18 | Aggressive Intestinal Symptoms Caused by Metastatic Tumors Originating from Primary Gastric Cancer in Pregnancy:A Case Report显示文摘Gastric carcinoma is extremely rare in pregnancy and the prognosis for this malignancy tends to be dismal.We herein describe a case of gastric cancer in pregnancy to alert clinicians to this rare possibility.A 29-year-old woman developed abdominal spastic pain and diarrhea during the 26 weeks of gestation and her condition was confusing and hard to recognize.The patient was initially misdiagnosed as enterogastritis and inflammatory intestinal obstruction and was finally confirmed by exploratory laparotomy with intestinal and peritoneum metastases.Because the disease was not detected early enough and progressed rapidly,the pregnancy was terminated by cesarean section at 30 weeks of gestation,and then followed by systemic chemotherapy,but eventually succumbed to the lethal pneumonia.Therefore,it is of great significance to alert clinicians to note this rare possibility and to consider the differential diagnosis of this disease in pregnant women with a long course of gastrointestinal symptoms that cannot be explained by pregnancy alone,and cancer should be suspected and tested with sophisticated diagnostic procedures. | Chunlin Zhao Jingru Ji Shenghui Lu Fang Wang Hailan Yang | 2023 | Maternal-Fetal Medicine2023，5，1： | 0 |
| 19 | Overdischarge-induced evolution of Cu dendrites and degradation of mechanical properties in lithium-ion batteries显示文摘The degradation of mechanical properties of overdischarge battery materials manifests as a significant effect on the energy density,safety,and cycle life of the batteries.However,establishing the correlation between depth of overdischarge and mechanical properties is still a significant challenge.Studying the correlation between depth of overdischarge and mechanical properties is of great significance to improving the energy density and the ability to resist abuse of the batteries.In this paper,the mechanical properties of the battery materials during the whole process of overdischarge from discharge to complete failure were studied.The effects of depth of overdischarge on the elastic modulus and hardness of the cathode of the battery,the tensile strength and the thermal shrinkage rate of the separator,and the performance of binder were investigated.The precipitation of Cu dendrites on the separator and cathode after dissolution of anode copper foil is a key factor affecting the performance of battery materials.The Cu dendrites attached to the cathode penetrate the separator,causing irreversible damage to the coating and base film of the separator,which leads to a sharp decline in the tensile strength,thermal shrinkage rate and other properties of the separator.In addition,the Cu dendrites wrapping the cathode active particles reduce the adhesion of the active particles binder.Meanwhile,the active particles are damaged,resulting in a significant decrease in the elastic modulus and hardness of the cathode. | Zixin Guo Siguo Yang Wenyang Zhao Shenghui Wang Jiong Liu Zhichao Ma Hongwei Zhao Luquan Ren | 2023 | Journal of Energy Chemistry2023，，3： | 0 |
| 20 | Heavy metals in sediments of Yellow Sea and East China Sea: Chemical speciation,distribution,influence factor,and contamination显示文摘Metal species and the degree of environmental pollution are related to the hydrogen sulfide(H_(2)S),an important product of early diagenesis that can react with metals to form stable compounds.To investigate the eff ects of H_(2)S to metals and evaluate metal environment eff ect in the sediments of the East China Sea(ECS)and Yellow Sea(YS),geochemical characteristic and spatial distribution of nine heavy metals and H_(2)S profile were studied.Higher H_(2)S content and lower metal content was observed in the sediments 10 cm in depth in the North Yellow Sea and the west coast of South Korea.The pollution load index(I_(pl))indicates that the southern coast of Shandong Peninsula underwent moderate pollution(I_(pl)=1)of heavy metals and no heavy metal pollution appeared in other areas(I_(pl)<1).To some extents,the ecological risk of Cd and As enrichment was moderately severe in all stations.The chance of heavy metal combination to be toxic in ECS and YS during summer was 21%.In addition,correlation between H_(2)S content and metals in both solid and porewater phases was obvious,corroborating important eff ect of H_(2)S on metal distribution.Moreover,H_(2)S could aff ect the spatial distributions of heavy metals in porewater directly and be indicative of potential biological eff ects of combined toxicant groups in the study region. | Miao ZHAO Shenghui ZHANG Haitao HAN Dawei PAN | 2021 | Journal of Oceanology and Limnology2021，39，4： | 0 |
