2Identification of coastal wetlands of international importance for waterbirds:a review of China Coastal Waterbird Surveys 2005–2013显示文摘Background:China's coastal wetlands belong to some of the most threatened ecosystems worldwide.The loss and degradation of these wetlands seriously threaten waterbirds that depend on wetlands.Methods:The China Coastal Waterbird Census was organized by volunteer birdwatchers in China's coastal region.Waterbirds were surveyed synchronously once every month at 14 sites,as well as irregularly at a further 18 sites,between September 2005 and December 2013.Results:A total of 75 species of waterbirds met the 1 % population level Ramsar listing criterion at least once at one site.The number of birds of the following species accounted for over 20 % of the total flyway populations at a single site:Mute Swan(Cygnus olor),Siberia Crane(Grus leucogeranus),Far Eastern Oystercatcher(Haematopus osculans),Bar-tailed Godwit(Limosa lapponica),Spotted Greenshank(Tringa guttifer),Great Knot(Calidris tenuirostris),Spoon-billed Sandpiper(Calidris pygmeus),Saunders' s Gull(Larus saundersi),Relict Gull(Larus relictus),Great Cormorant(Phalacrocorax carbo),Eurasian Spoonbill(Platalea leucorodia),Black-faced Spoonbill(Platalea minor) and Dalmatian Pelican(Pelecanus crispus).A total of 26 sites supported at least one species of which their number met the1 % criterion.Forty-two species met the 1 % criterion in the Yellow River Delta,Shandong;29 at the Cangzhou coast,Hebei and 26 species at the Lianyungang coast,Jiangsu.Conclusions:The results highlight the international importance of China's coastal wetlands for waterbirds.This study also demonstrates that participation of local birdwatchers in waterbird surveys results in data that are invaluable not only for understanding the current status of waterbirds in China's coastal regions but also for waterbird conservation and management.Qingquan Bai Jianzhong Chen Zhihong Chen Guotai Dong Jiangtian Dong Wenxiao Dong Vivian Wing Kan Fu Yongxiang Han Gang Lu Jing Li Yang Liu Zhi Lin Derong Meng Jonathan Martinez Guanghui Ni Kai Shan Renjie Sun Suixing Tian Fengqin Wang Zhiwei Xu Yat-tung Yu Jin Yang Zhidong Yang Lin Zhang Ming Zhang Xiangwu Zeng 2015Chinese Birds2015,,3:20
3Assessing the relative role of climate change and human activities in sandy desertification of Ordos region, China显示文摘Climate change and human activities are driving forces of sandy desertification and the relative role of them in sandy desertification is the hot point in related researches. A study was carried to assess the relative role of climate change and human activities in sandy desertification of Ordos region in China. Potential NPP and the difference between potential and actual NPP were selected as indicators to assess the relative role of climate change and human activities in sandy desertification, respectively. Assessing methods were built based on some scenarios for the reversion and expansion of sandy desertification and the relative role of climate change and human activities in sandy desertification of Ordos region were assessed from 1981 to 2000. The results showed that although some local places experienced an expansion of sandy desertification, the change of sandy desertification of Ordos region from 1981 to 2000 showed a stably reversing trend. The relative role of climate change and human activities in sandy desertification of Ordos region varied at different temporal and spatial scales in the reversion and expansion processes. In the reversion of sandy desertification, climate change was the dominant factor in the period of 1981 to 1990 and the reversed areas mainly induced by climate change including Mu Us sandy land and the transition zone between temperate steppe and temperate deciduous scrubs in north east of Ordos region; however, human activities controlled the reversed process during the period from 1991 to 2000 and the areas mainly induced by human activities distributed in all banners of Ordos region. In the expansion of sandy desertification, human activities were the dominant factor in the period of 1981 to 1990 and the expanded areas mainly included the regions around common boundary of Hanggin, Dalad Banners and Dongsheng City; however, climate change dominated the expansion of sandy desertification from 1991 to 2000, the expanded areas equably distributed in the whole of Ordos region except the south east of Otog Qian, Uxin and Jungar Banners.XU DuanYang KANG XiangWu LIU ZhiLi ZHUANG DaFang PAN JianJun 2009Science China Earth Sciences2009,52,6:19
4Individual idea about the micro-invasive aspiration and drainage of intracranial hematoma显示文摘AIM: This study aimed to expound the individual idea of micro-invasive surgery from pre-operative preparation, intra-operative processing and post-operative management. METHODS: Pre-operative preparation was improved by analyzing pathological factors and hematoma property, and considering patients' age, basic disease, blood pressure control, with persistent haemorrhagia/rehaemorrhagia or not, operative occasion choice, positioning and other procedures. In the surgery, positioner was used. Initial aspiration volume was cautiously controlled. After operation, vital signs of patients were kept stable by cautiously using hematoma liquefacient and combining with free radical scavenger. RESULTS: The core content of individual micro-invasive surgery was mainly to relieve intracranial pressure. Under the condition of sufficient pre-operative preparation known by patients' family members, precise positioning was determined and individual therapeutic regimen was made. Meanwhile, caution should be taken in hematoma aspiration. Liquefaction and drainage should be paid more attention, and complications were processed actively. CONCLUSION: During the process of micro-invasive evacuation of intracranial hematoma for treating cerebral hemorrhage, attention should be paid to analyzing cerebral hematoma etiology and pathophysiological mechanism, and individual idea should be considered in surgical treatment aiming at patients' concrete disease condition.Zhouping Tang Feng Xu Xingyong Chen Xiangwu Meng Wei Hu Suiqiang Zhu Wei Wang 2007Neural Regeneration Research2007,2,12:12
5Hsa-miR-1246, hsa-miR-320a and hsa-miR-196b-5p inhibitors can reduce the cytotoxicity of Ebola virus glycoprotein in vitro显示文摘Ebola virus(EBOV)causes a highly lethal hemorrhagic fever syndrome in humans and has been associated with mortality rates of up to 91%in Zaire,the most lethal strain.Though the viral envelope glycoprotein(GP)mediates widespread inflammation and cellular damage,these changes have mainly focused on alterations at the protein level,the role of microRNAs(miRNAs)in the molecular pathogenesis underlying this lethal disease is not fully understood.Here,we report that the miRNAs hsa-miR-1246,hsa-miR-320a and hsa-miR-196b-5p were induced in human umbilical vein endothelial cells(HUVECs)following expression of EBOV GP.Among the proteins encoded by predicted targets of these miRNAs,the adhesion-related molecules tissue factor pathway inhibitor(TFPI),dystroglycan1(DAG1)and the caspase 8 and FADD-like apoptosis regulator(CFLAR)were significantly downregulated in EBOV GP-expressing HUVECs.Moreover,inhibition of hsa-miR-1246,hsa-miR-320a and hsa-miR-196b-5p,or overexpression of TFPI,DAG1 and CFLAR rescued the cell viability that was induced by EBOV GP.Our results provide a novel molecular basis for EBOV pathogenesis and may contribute to the development of strategies to protect against future EBOV pandemics.SHENG MiaoMiao ZHONG Ying CHEN Yang DU JianChao JU XiangWu ZHAO Chen ZHANG GuiGen ZHANG LiFang LIU KangTai YANG Ning XIE Peng LI DangSheng ZHANG Michael Q.

6Hematoma enlargement-related factors in hypertensive cerebral hemorrhage显示文摘BACKGROUND:Continuous hemorrhage or hematoma enlargement often occurs following cerebral hemorrhage attacks. OBJECTIVE: To retrospectively analyze the influential factors for hematoma enlargement in patients with hypertensive cerebral hemorrhage prior to minimally invasive surgery. DESIGN, TIME AND SETTING: A comparative analysis of 90 patients with cerebral hemorrhage undergoing minimally invasive surgery at the Department of Neurology, Tongji Hospital of Tongji Medical College, Huazhong University of Science and Technology between April 2005 and February 2007. PARTICIPANTS: Fifty-eight males and thirty-one females aged (52.7 ± 5.23) years (range, 28-73 years). METHODS: Cranial CT was performed twice to objectively identify hematoma enlargement. Patients with hematoma enlargement prior to surgery were selected as the observation group (n = 30), and those with no obvious hematoma changes served as the control group (n = 60). Following cranial CT localization, the two groups underwent minimally invasive hematoma aspiration and drainage, according to Standardized Treatment Guidelines for Micro-invasive Aspiration and Drainage of Intracranial Hematoma. MAIN OUTCOME MEASURES: Hemorrhage site, coagulation function, diabetes history, and clinical symptoms. RESULTS: There were no significant differences in hemorrhage sites between the two groups (χ2 = 2.262, P > 0.05). The percent of intemperance patients in the observation group was significantly larger than the control group (χ2 = 6.923, P < 0.01). No significant differences in terms of percent of coagulation dysfunction or diabetes were determined between the two groups (χ2 = 0.03, 0.08, P > 0.05). The percent of patients with clinical deterioration was significantly higher in the observation group, compared to the control group (χ2 = 25.57, P < 0.01). CONCLUSION: Intemperance and preoperative clinical deterioration may increase incidence of hematoma enlargement prior to minimally invasive surgery in patients with hypertensive cerebral hemorrhage.Dengji Pan Zhouping Tang Feng Xu Di Chen Xingyong Chen Xiangwu Meng Suiqiang Zhu Wei Wang 2008Neural Regeneration Research2008,3,8:4

10Gossip-Based Resource Location Strategy in Interest Community for P2P Networks显示文摘Resource location strategy has become very popular for mass data distribution in complex and dynamic network. Searching for the objects is a fundamental problem to unstructured Peer to peer(P2P) networks. In this paper, we propose a resource location strategy for user requirements, which employs the collaborative exchange of information between peers to construct interest communities. This strategy can gather similar peers and disseminate useful information among them. Furthermore, we design an algorithm in unstructured P2 P systems named Appropriate degree gossip search algorithm(ADGSA). Using this search algorithm, the performance including search success ratio, recall rate and search response time has been improved dramatically. An efficient resource location system with a fast organization of users cluster based on their requirements can be provided, preventing the creation of unliked communities. The simulation results show that our strategy has better search efficiency, short response time and high recall ratio.HE Ming ZHANG Yujie MENG Xiangwu 2015Chinese Journal of Electronics2015,24,2:2

12Effects of fabric anisotropy on elastic shear modulus of granular soils显示文摘The fabric anisotropy of a granular soil deposit can strongly infl uence its engineering properties and behavior. This paper presents the results of a novel experimental study designed to examine the effects of fabric anisotropy on smallstrain stiffness and its evolution with loading on the elastic shear modulus of granular materials under a K0 condition. Two primary categories of fabric anisotropy, i.e., deposition-induced and particle shape-induced, are investigated. Toyoura sand deposits with relative densities of 40% and 80% were prepared using deposition angles oriented at 0o and 90o. Piezoelectric transducers were used to obtain the elastic shear modulus in the vertical and horizontal directions(Gvh and Ghh). The measurements indicate distinct differences in the values of G with respect to the different deposition angles. Particle shapeinduced fabric anisotropy was examined using four selected sands. It was concluded that sphericity is a controlling factor dominating the small-strain stiffness of granular materials. The degree of fabric anisotropy proves to be a good indicatorin the characterization of stress-induced fabric evolution during loading and unloading stress cycles. The experimental data were used to calibrate an existing micromechanical model, which was able to represent the behavior of the granular material and the degree of fabric anisotropy reasonably well.Li Bo Zeng Xiangwu 2014Earthquake Engineering and Engineering Vibration2014,13,2:2
13The discovery of Jurassic plants in Shenzhen of Guangdong, southern China and related significance显示文摘Investigations of major marine and non-marine geologic and biotic events across the Triassic-Jurassic transition rely predominantly on detailed stratigraphic frameworks and biodiversity analyses. The alternating sequences of marine and terrestrial Triassic-Jurassic formations in Guangdong Province represent one of the most remarkable coal-bearing series in southern China. The Lower Jurassic Jinji Formation is widely distributed in Guangdong, with continuously outcropped sections and rich marine and non-marine fossil fauna. However, as little research has been conducted on fossil plant remains in the Jinji Formation, it is difficult to understand the systematics,diversity, and floral aspects of the Jurassic. Here we report on the recent collection of rich fossil plants from the Jinji Formation in the Dapeng area of Shenzhen, southern Guangdong Province. Our studies demonstrate taxonomical affiliations, preservation status, and diversity features of these plant fossils, which are marked by the close association of densely preserved, pinnae and rachis connected leaves, and the bennettitalean reproductive organs of Williamsoniella, which may represent an Early Jurassic plant community dominated by Otozamites of the bennettitales.This work not only represents the first discovery of fossil plants in the Shenzhen area, but is also the first documentation of Jurassic plants in Guangdong and the Pearl River Delta regions. Research related to these plant fossils will be helpful in the correlation of the Early Mesozoic coal-bearing strata in Guangdong, and will provide a deeper understanding of variations in plant diversity of the Triassic and Jurassic transition in southern China. Additionally, it will provide terrestrial plant evidence for explorations in Jurassic palaeoecology, palaeoclimatology,and palaeogeography of southern China.Yongdong Wang Xiangwu Wu Xiaoju Yang Wei Duan Liqin Li 2014Chinese Science Bulletin2014,59,28:2
14High-Performance 3-D Fiber Network Composite Electrolyte Enabled with Li-Ion Conducting Nanofibers and Amorphous PEO-Based Cross-Linked Polymer for Ambient All-Solid-State Lithium-Metal Batteries显示文摘Solid electrolytes have gained attention recently for the development of next-generation Li-ion batteries since they can fun-damentally improve the battery stability and safety.Among various types of solid electrolytes,composite solid electrolytes(CSEs)exhibit both high ionic conductivity and excellent interfacial contact with the electrodes.Incorporating active nanofib-ers into the polymer matrix demonstrates an effective method to fabricate CSEs.However,current CSEs based on traditional poly(ethylene oxide)(PEO)polymer suffer from the poor ionic conductivity of PEO and agglomeration effect of inorganic fillers at high concentrations,which limit further improvements in Li+conductivity and electrochemical stability.Herein,we synthesize a novel PEO based cross-linked polymer(CLP)as the polymer matrix with naturally amorphous structure and high room-temperature ionic conductivity of 2.40×10^(−4)S cm^(−1).Li_(0.3)La_(0.557)TiO_(3)(LLTO)nanofibers are incorporated into the CLP matrix to form composite solid electrolytes,achieving enhanced ionic conductivity without showing filler agglomeration.The high content of Li-conductive nanofibers improves the mechanical strength,ensures the conductive network,and increases the total Li+conductivity to 3.31×10^(−4)S cm^(−1).The all-solid-state Li|LiFePO_(4)batteries with LLTO nanofiber-incorporated CSEs are able to deliver attractive specific capacity of 147 mAh g^(−1)at room temperature,and no evident dendrite is found at the anode/electrolyte interface after 100 cycles.Chaoyi Yan Pei Zhu Hao Jia Jiadeng Zhu R.Kalai Selvan Ya Li Xia Dong Zhuang Du Indunil Angunawela Nianqiang Wu Mahmut Dirican Xiangwu Zhang 2019Advanced Fiber Materials2019,1,1:2
15Gamma(ɣ)‑MnO_(2)/rGO Fibered Cathode Fabrication from Wet Spinning and Dip Coating Techniques for Cable‑Shaped Zn‑Ion Batteries显示文摘Cable/fber-shaped Zn-ion batteries are designed to power wearable electronics that require high fexibility to operate on human body.However,one of technical challenges of these devices is the complexity and high cost for manufacturing fbered cathode.In this work,we demonstrated gamma manganese oxide(ɣ-MnO_(2))/reduced graphene oxide(rGO)fbered cathode fabrication using facile and cost-efective fber production and active material coating techniques.Specifcally,rGO fbers were fabricated via wet spinning,followed by chemical reduction with hydroiodic acid(HI).The synthesized rGO fber bundle was then dip-coated with a mixture ofɣ-MnO_(2),carbon black or multi-walled carbon nanotubes,and xanthan gum or polyvinylidene fuoride binder to obtainɣ-MnO_(2)/rGO fbered cathode.We studied the efect of binders and conductive materials on physical properties and electrochemical performance of the fbered cathode.It was found that hydrophobic binder had more benefts than hydrophilic binder by providing higher active material loading,better coating layer homogeneity,and more stable electrochemical performance.Cable-shaped Zn-ion batteries(CSZIBs)were then assembled by using theɣ-MnO_(2)/rGO fbered cathode,Zn wire anode,and xanthan gum polymeric gel electrolyte with 2 M ZnSO_(4) and 0.2 M MnSO_(4) salts without a separator.We investigated the battery assembling procedure on a glass slide(prototype ZIB)and in a plastic tube(cable-shaped ZIB),and evaluated their electrochemical performance.The CSZIB showed promising maximum capacity of~230 mAh/g with moderate cycling stability(80%capacity retention after 200 cycles)and high fexibility by maintaining the potential after consecutive pressing for 200 times under controlled pressing distance,duration,and testing speed.Finally,we explored ion intercalation behaviours and proposed a H^(+)/Zn^(2+)co-intercalation mechanism in ZIB withɣ-MnO_(2) active material.Nakarin Subjalearndee Nanfei He Hui Cheng Panpanat Tesatchabut Priew Eiamlamai Pimpa Limthongkul Varol Intasanta Wei Gao Xiangwu Zhang 2022Advanced Fiber Materials2022,4,3:2
16Analysis of Total Antimony in Fresh Fruit and Pollution Evaluation in Hunan Province显示文摘[Objective]The content of total antimony(Sb) in fresh fruit was investigated and its pollution was evaluated,to provide the basic data for diet exposure evaluation.[Method]The content of total Sb in 194 samples was detected by hydride generation-atomic fluorescence spectrometry(HG-AFS),and the Sb pollution in several fruits was evaluated by the method of single factor pollution index. [Result]The mean of total Sb was 0.005 6 mg / kg,and the median was 0.003 8mg / kg. The minimum value was not detected while the maximum value was 0.21 mg / kg,and the confidence interval was ND-0.019 mg / kg(P5-P95). The medians of total Sb content in different fruits successively were dragon fruit(0.011 0 mg / kg) > kiwi fruit(0.008 0 mg / kg) > peach(0.006 0 mg / kg). According to the method of single factor pollution index,the index from all samples was less than 0.2,suggesting that the samples involved were under the normal background value.[Conclusion]The Sb was detected in all samples but under the background value,and it was concluded that there was no Sb pollution in fresh fruit in Hunan Province.Tan Xiangwu Huang Huxin Xiao Shenglan Ma Jinhui Xiao Fuyuan Peng Wei Huang Yan 2016Plant Diseases and Pests2016,7,4:2
17Accuracy assessment and error analysis for diameter at breast height measurement of trees obtained using a novel backpack LiDAR system显示文摘Background: The LiBackpack is a recently developed backpack light detection and ranging(LiDAR) system that combines the flexibility of human walking with the nearby measurement in all directions to provide a novel and efficient approach to LiDAR remote sensing, especially useful for forest structure inventory. However, the measurement accuracy and error sources have not been systematically explored for this system.Method: In this study, we used the LiBackpack D-50 system to measure the diameter at breast height(DBH) for a Pinus sylvestris tree population in the Saihanba National Forest Park of China, and estimated the accuracy of LiBackpack measurements of DBH based on comparisons with manually measured DBH values in the field. We determined the optimal vertical slice thickness of the point cloud sample for achieving the most stable and accurate LiBackpack measurements of DBH for this tree species, and explored the effects of different factors on the measurement error.Result: 1) A vertical thickness of 30 cm for the point cloud sample slice provided the highest fitting accuracy(adjusted R2= 0.89, Root Mean Squared Error(RMSE) = 20.85 mm);2) the point cloud density had a significant negative, logarithmic relationship with measurement error of DBH and it explained 35.1% of the measurement error;3) the LiBackpack measurements of DBH were generally smaller than the manually measured values, and the corresponding measurement errors increased for larger trees;and 4) by considering the effect of the point cloud density correction, a transitional model can be fitted to approximate field measured DBH using LiBackpackscanned value with satisfactory accuracy(adjusted R2= 0.920;RMSE = 14.77 mm), and decrease the predicting error by 29.2%. Our study confirmed the reliability of the novel LiBackpack system in accurate forestry inventory, set up a useful transitional model between scanning data and the traditional manual-measured data specifically for P.sylvestris, and implied the applicable substitution of this new approach for more species, with necessary parameter calibration.Yuyang Xie Jie Zhang Xiangwu Chen Shuxin Pang Hui Zeng Zehao Shen 2020Forest Ecosystems2020,7,3:2
