| 1 | Multi target pigs tracking loss correction algorithm based on Faster R-CNN显示文摘In order to solve the problem that target tracking frames are lost during the visual tracking of pigs,this research proposed an algorithm for multi target pigs tracking loss correction based on Faster R-CNN.The video of live pigs was processed by Faster R-CNN to get the object bounding box.Then,the SURF and background difference method were combined to predict whether the target pig will be occluded in the next frame.According to the occlusion condition,the maximum value of the horizontal and vertical coordinate offset of the bounding box in the adjacent two frames of the frame image in continuous N(N is the value of the video frame rate)were calculated.When bounding boxes in a video frame are merged into one bounding box,this maximum value was used to correct the current tracking frame offset in order to achieve the purpose of solving the tracking target loss problem.The experiment results showed that the success rate range of RP Faster-RCNN in the data set was 80%-97% while in term of Faster-RCNN was 40%-85%.And the average center point error of RP Faster-RCNN was 1.46 lower than Faster-RCNN which was about 2.60.The new algorithm was characterized by good robustness and adaptability,which could solve the problem of missing tracking target and accurately track multiple targets when the targets occlude each other. | Longqing Sun Yuanbing Zou Yan Li Zhengda Cai Yue Li Bing Luo Yan Liu Yiyang Li | 2018 | International Journal of Agricultural and Biological Engineering2018，11，5： | 7 |
| 2 | Use of acupuncture to treat cerebral infarction in the last 10 years A Scopus-based literature analysis显示文摘OBJECTIVE: To identify global research trends in the use of acupuncture to treat cerebral infarction. DATA RETRIEVAL: We performed a bibliometric analysis of studies on the use of acupuncture to treat cerebral infarction published during 2002-2011, retrieved from Scopus, using the Key Words of acupuncture and cerebral infarction or ischemic stroke. SELECTION CRITERIA: Inclusion criteria: peer-reviewed articles on the use of acupuncture to treat cerebral infarction indexed in Scopus and published between 2002 and 2011; types of publications were original research articles, reviews, meeting abstracts, proceedings papers, book chapters, editorial material, and news items. Exclusion criteria: articles that required manual searching or telephone access; documents that were not published in the public domain; and corrected papers. MAIN OUTCOME MEASURES: (a) Annual publication output; (b) language of publication; (c) type of publication; (d) key words of publication; (e) publication by research field; (f) publication by journal; (g) publication by country and institution; (h) publication by author; (i) most-cited papers between 2002 and 2006; and (j) most-cited papers between 2007 and 2011. RESULTS: A total of 160 publications on the use of acupuncture to treat cerebral infarction from 2002-2011 were retrieved from Scopus. The number of publications increased gradually over the 10-year study period; most were written in Chinese or English. Articles and reviews constituted the major types. The most frequent key word used was acupuncture. The most prolific journals in this area were Zhongguo Zhen Jiu and the Chinese Journal of Clinical Rehabilitation. Of the 160 publications retrieved, half came from Chinese authors and institutions. Tianjin University of Traditional Chinese Medicine was the most prolific research institute. Two papers were cited 30 times; they were published in 2002 and 2009, respectively. CONCLUSION: In the field of neuroscience, there is little literature on acupuncture for cerebral infarction. The most-cited papers were cited 30 times in the past 3 years. We believe that, with advances in the study of mechanisms in neurobiology, research on acupuncture will also advance and will become the concern of more scholars. | Jiajun Chen Min Yao Yunhua Zhao Xiya Jin Yuanbing Li Lihong Huang | 2012 | Neural Regeneration Research2012，7，36： | 7 |
| 3 | Aerosol Data Assimilation Using Data from Fengyun-3A and MODIS:Application to a Dust Storm over East Asia in 2011显示文摘Aerosol optical depth(AOD) is the most basic parameter that describes the optical properties of atmospheric aerosols,and it can be used to indicate aerosol content. In this study, we assimilated AOD data from the Fengyun-3 A(FY-3 A) and MODIS meteorological satellite using the Gridpoint Statistical Interpolation three-dimensional variational data assimilation system. Experiments were conducted for a dust storm over East Asia in April 2011. Each 0600 UTC analysis initialized a24-h Weather Research and Forecasting with Chemistry model forecast. The results generally showed that the assimilation of satellite AOD observational data can significantly improve model aerosol mass prediction skills. The AOD distribution of the analysis field was closer to the observations of the satellite after assimilation of satellite AOD data. In addition, the analysis resulting from the experiment assimilating both FY-3 A/MERSI(Medium-resolution Spectral Imager) AOD data and MODIS AOD data had closer agreement with the ground-based values than the individual assimilation of the two datasets for the dust storm over East Asia. These results suggest that the Chinese FY-3 A satellite aerosol products can be effectively applied to numerical models and dust weather analysis. | Xiaoli XIA Jinzhong MIN Feifei SHEN Yuanbing WANG Chun YANG | 2019 | Advances in Atmospheric Sciences2019，36，1： | 6 |
| 4 | Economic feasibility of large-scale hydro–solar hybrid power including long distance transmission显示文摘Solar PV is expected to become the most cost-competitive renewable energy owing to the rapidly decreasing cost of the system. On the other hand, hydropower is a high-quality and reliable regulating power source that can be bundled with solar PV to improve the economic feasibility of long-distance transmitted power. In this paper, a quantification model is established taking into account the regulating capacity of the reservoir, the characteristics of solar generation, and cost of hydro and solar PV with long-distance transmission based on the installed capacity ratio of hydro–solar hybrid power. Results indicate that for hydropower stations with high regulating capacity and generation factor of approximately 0.5, a hydro–solar installed capacity ratio of 1:1 will yield overall optimal economic performance, whereas for hydropower stations with daily regulating capacity reservoir and capacity factor of approximately 0.65, the optimal hydro–solar installed capacity ratio is approximately 1:0.3. In addition, the accuracy of the approach used in this study is verified through operation simulation of a hydro–solar hybrid system including ultra high-voltage direct current(UHVDC) transmission using two case studies in Africa. | Zhenchen Deng Jinyu Xiao Shikun Zhang Yuetao Xie Yue Rong Yuanbing Zhou | 2019 | Global Energy Interconnection2019，2，4： | 6 |
| 5 | Individual pig object detection algorithm based on Gaussian mixture model显示文摘The background models are crucially important for the object extraction for moving objects detection in a video.The Gaussian mixture model(GMM)is one of popular methods in the background models.Gaussian mixture model which applied to the pig target detection has some shortcomings such as low efficiency of algorithm,misjudgment points and ghosts.This study proposed an improved algorithm based on adaptive Gaussian mixture model,to overcome the deficiencies of the traditional Gaussian mixture model in pig object detection.Based on Gaussian mixture background model,this paper introduced two new parameters of video frames m and T0.The Gaussian distribution was scanned once every m frames,the excessive Gaussian distribution was deleted to improve the convergence speed of the model.Meanwhile,using different learning rates to suppress ghosts,a higher decreasing learning rate was adopted to accelerate the background modeling before T_(0),the background model would become stable as the time continued and a smaller learning rate could be used.In order to maintain a stable background and reduce noise interference,a fixed learning rate after T_(0) was used.Results of experiments indicated that this algorithm could quickly build the initial background model,detect the moving target pigs,and extract the complete contours of the target pigs’.The algorithm is characterized by good robustness and adaptability. | Li Yiyang Sun Longqing Zou Yuanbing Li Yue | 2017 | International Journal of Agricultural and Biological Engineering2017，10，5： | 6 |
| 6 | Development and CommercialApplication of RSDS-II Technology for Selective Hydrodesulfurization of FCC Naphtha显示文摘The FCC naphtha selective hydrodesulfurization technology(RSDS-II)has been tested with different feedstocks in pilot scale.The results show that RSDS-II technology is viable in terms of its adaptability to different feedstocks.To produce gasoline with a sulfur content of less than 50μg/g by the RSDS-II technology,the gasoline RON loss is less than 1.8,0.9and 0.2 units,respectively,upon processing the conventional high-sulfur and high-olefin FCC naphtha,the high-sulfur MIP naphtha,and the medium-sulfur or low-sulfur MIP naphtha.Upon using the naphtha produced from pre-hydrotreated FCC feedstock as the RSDS-II feedstock to manufacture gasoline with a sulfur content of lower than 10μg/g,the RON loss does not exceed 1.0 unit.The RSDS-II technology has been commercialized successfully at many refineries.The result of operating commercial RSDS-II unit at the Shanghai Petrochemical Company has revealed that upon processing a feedstock containing 38.7 v% —43.3 v% of olefins and 250—470 mg/g of sulfur,the sulfur content in the treated gasoline ranges from 33μg/g to 46μg/g and the RON loss is equal to only 0.3—0.6 units.Till now this RSDS-II unit has been operating smoothly over 30 months.Thanks to its high HDS activity and good selectivity,the RSDS-II technology can meet the refinery’s needs for adequate upgrading of gasoline. | Qu Jinhua Xi Yuanbing Li Mingfeng Pan Guangcheng Jin Xin Gao Xiaodong Nie Hong | 2013 | China Petroleum Processing & Petrochemical Technology2013，15，3： | 6 |
| 7 | Causes and underlying dynamic processes of the mid-winter suppression in the North Pacific storm track显示文摘Baroclinic wave activity in the North Pacific exhibit peaks in late fall and early spring, and a local minimum in midwinter, when by linear baroclinic instability theory it should attain its maximum. This counterintuitive phenomenon, or'midwinter suppression'(MWM) as called, is investigated with a functional analysis apparatus, multiscale window transform(MWT), and the MWT-based theory of canonical transfer and localized multi-scale energetics analysis, together with a feature tracking technique, using the data from the European Centre for Medium-Range Weather Forecasts ReAnalysis(ERA-40). It is found that the MWM results from a variety of different physical processes, including baroclinic canonical transfer, diabatic effect, energy flux divergence, and frictional dissipation. On one hand, baroclinic canonical transfer and diabatic effect achieve their respective maxima in late fall. More transient available potential energy is produced and then converted to transient kinetic energy, resulting in a stronger storm track in late fall than in midwinter. On the other hand, in early spring, although baroclinic instability and buoyancy conversion are weak, energy flux convergences are substantially strengthened, leading to a net energy inflow into the storm track. Meanwhile, frictional dissipation is greatly reduced in spring; as a result, less transient energy is dissipated in early spring than in midwinter. It is further found that the weakening of baroclinic canonical transfer in midwinter(compared to late fall) is due to the far distance between the storm and the jet stream(located at its southernmost point), which suppresses the interaction between them. Regarding the increase in energy flux convergence in early spring, it appears to originate from the increase(enhancement) in the number(strength) of storms from the upstream into the Pacific. | Yuanbing ZHAO X.San LIANG | 2019 | Science China Earth Sciences2019，62，5： | 4 |

| 9 | Optimal design on the high-temperature mechanical properties of porous alumina ceramics based on fractal dimension analysis显示文摘Fractal theory and regression analysis were employed for the first time to investigate the effect of pore size and pore distribution on high-temperature mechanical properties of porous alumina ceramics(PAC). In the present work, PAC with the comparable porosity, different pore sizes and pore distributions were prepared using carbon black as the pore-forming agent. Particular emphasis in this study was placed on the establishment of correlation between the thermal shock resistance and pore properties. The relationship between fractal dimension(D_f) and thermal shock resistance parameter(R_(st)) in specimens presented the negative power function, indicating that low D_f could benefit the improvement of thermal shock resistance in specimens. The results showed that the increase of pore size and pore sphericity leads to a reduced D_f, the enhanced hot modulus of rupture(HMOR) and R_(st). The decrease of proportion of micro-pores below 2 μm, the increase of mean pore size and pore sphericity could result in the decrease of D_f, and then improve R_(st) and HMOR of specimens. Based on the correlation between R_(st) and pore characteristics, PAC with improved thermal shock resistance could be achieved when their pore structure meets the above features. | Jingjing LIU Wenlong HUO Xiaoyan ZHANG Bo REN Yuanbing Li Zaijuan ZHANG Jinlong YANG | 2018 | Journal of Advanced Ceramics2018，7，2： | 4 |
| 10 | The atlas of cytoophidia in Drosophila larvae显示文摘In 2010,cytidine 50-triphosphate synthase(CTPS)was reported to form the filamentous or serpentine structure in Drosophila,which we termed the cytoophidium.In the last decade,CTPS filaments/cytoophidia have been found in bacteria,budding yeast,human cells,mice,fission yeast,plants,and archaea,indicating that this mechanism is highly conserved in evolution.In addition to CTPS,other metabolic enzymes have been identified to have the characteristics of forming cytoophidia or similar advanced structures,demonstrating that this is a basic strategy of cells.Nevertheless,our understanding of the physiological function of the cytoophidium remains incomplete and elusive.Here,we took the larva of Drosophila melanogaster as a model to systematically describe the localization and distribution of cytoophidia in different tissues during larval development.We found that the distribution pattern of CTPS cytoophidia is dynamic and heterogenic in larval tissues.Our study provides a road map for further understanding of the function and regulatory mechanism of cytoophidia. | Yuanbing Zhang Jingnan Liu Ji-Long Liu | 2020 | Journal of Genetics and Genomics2020，47，6： | 2 |
| 11 | Development of RSDS-III Technology for Ultra-Low-Sulfur Gasoline Production显示文摘The 3rd generation catalytic cracking naphtha selective hydrodesulfurization(RSDS-III) technology developed by RIPP included the catalysts selective adjusting(RSAT) technology, the development of new catalysts and optimized process conditions. The pilot plant test results showed that the RSDS-III technology could be adapted to different feedstocks. The sulfur content dropped from 600 μg/g and 631 μg/g to 7 μg/g and 9 μg/g, respectively, by RSDS-III technology when feed A and feed B were processed to meet China national V gasoline standard, with the RON loss of products equating to 0.9 units and 1.0 unit, respectively. While the feed C with a medium sulfur content was processed according to the full-range naphtha hydrotreating technology, the sulfur content dropped from 357 μg/g in the feed to 10 μg/g in gasoline, with the RON loss of product decreased by only 0.6 units. Thanks to the high HDS activity and good selectivity of RSDS-III technology, the ultra-low-sulfur gasoline meeting China V standard could be produced by the RSDS-III technology with little RON loss. | Xi Yuanbing Zhang Dengqian Chu Yang Gao Xiaodong | 2015 | China Petroleum Processing & Petrochemical Technology2015，17，2： | 2 |
| 12 | Evolutionary biogeography on Ophiocordyceps sinensis:An indicator of molecular phylogeny to geochronological and ecological exchanges显示文摘The fungus Ophiocordyceps sinensis is endemic to the vast region of the Qinghai-Tibetan plateau(QTP).The unique and complex geographical environmental conditions have led to the 'sky island' distribution structure of O.sinensis.Due to limited and unbalanced sample collections,the previous data on O.sinensis regarding its genetic diversity and spatial structure have been deemed insufficient.In this study,we analyzed the diversity and phylogeographic structures of O.sinensis using internally transcribed spacer region(ITS) and 5-locus datasets by a large-scale sampling.A total of 111 haplotypes of ITS sequences were identified from 948 samples data of the fungus O.sinensis,with representing high genetic diversity,and 8 phylogenetic clades were recognized in O.sinensis.Both the southeastern Tibet and the northwestern Yunnan were the centers of genetic diversity and genetic differentiation of the fungus,and they were inferred as the glacial refugia in the Quaternary.Three distribution patterns were identified to correspond to the 8 clades,including but not limited to the coexistence of widely and specific local distributive structures.It also revealed that the differentiation pattern of O.sinensis did not fit for the isolation-by-distance model.The differentiation into the 8 clades occurred between 1.56 Myr and6.62 Myr.The ancestor of O.sinensis most likely originated in the late Miocene(6.62 Myr) in the northwestern Yunnan,and the Scene A-C of the Qinghai-Tibetan movements may have played an important role in the differentiation of O.sinensis during the late Miocene-Pliocene periods.Our current results provide a much clearer and detailed understanding of the genetic diversity and geographical spatial distribution of the endemic alpine fungus O.sinensis.It also revealed that the geochronology resulting from paleogeology could be cross-examined with biomolecular clock at a finer scale. | Yongdong Dai Changkui Wu Feng Yuan Yuanbing Wang Luodong Huang Zihong Chen Wenbo Zeng Yao Wang Zhuliang Yang Pusheng Zeng Paul Lemetti Xuanxue Mo Hong Yu | 2020 | Geoscience Frontiers2020，11，3： | 2 |
| 13 | Kinetic Model of LCO Selective Hydrogenation on NiMoW/Al_(2)O_(3) Catalyst显示文摘In order to investigate the hydrofining process of LCO for producing aromatics and gasoline,the selective hydrogenation of polycyclic aromatic hydrocarbons(PAHs),a major component of light cycle oil(LCO),was studied using a NiMoW/Al_(2)O_(3)catalyst.Based on the study of the reversible hydrogenation reaction,PAHs in the selective hydrogenation process could be effectively simulated by the modeled CH and CH_(2) groups,and the hydrodesulfurization and hydrodenitrogenation kinetic models could be further established in this process.The results showed that the kinetic models developed could fit the experimental data effectively and predict the content of S,N,and aromatics in the selective hydrogenation products of LCO. | Ju Xueyan Zhang Kui Xi Yuanbing Wang Zhe Nie Hong | 2022 | China Petroleum Processing & Petrochemical Technology2022，24，3： | 2 |
