| 1 | Multiple UAVs/UGVs heterogeneous coordinated technique based on Receding Horizon Control (RHC) and velocity vector control显示文摘Multiple unmanned air vehicles(UAVs)/unmanned ground vehicles(UGVs) heterogeneous cooperation provides a new breakthrough for the effective application of UAV and UGV.On the basis of introduction of UAV/UGV mathematical model,the characteristics of heterogeneous flocking is analyzed in detail.Two key issues are considered in multi-UGV subgroups,which are Reynolds Rule and Virtual Leader(VL).Receding Horizon Control(RHC) with Particle Swarm Optimization(PSO) is proposed for multiple UGVs flocking,and velocity vector control approach is adopted for multiple UAVs flocking.Then,multiple UAVs and UGVs heterogeneous tracking can be achieved by these two approaches.The feasibility and effectiveness of our proposed method are verified by comparative experiments with artificial potential field method. | DUAN HaiBin ZHANG YunPeng LIU SenQi | 2011 | Science China(Technological Sciences)2011，54，4： | 15 |
| 2 | Potential and Suitability Evaluation of CO_2 Geological Storage in Major Sedimentary Basins of China,and the Demonstration Project in Ordos Basin显示文摘From 2010 to 2012, the China Geological Survey Center for Hydrogeology and Environmental Geology Survey(CHEGS) carried out the project 'Potential evaluation and demonstration project of CO2 Geological Storage in China'. During this project, we developed an evaluation index system and technical methods for the potential and suitability of CO2 geological storage based on China's geological conditions, and evaluated the potential and suitability of the primary basins for CO2 geological storage, in order to draw a series of regional scale maps(at a scale of 1:5000000) and develop an atlas of the main sedimentary basins in China. By using these tools, we delineated many potential targets for CO2 storage. We also built techniques and methods for site selection and the exploration and assessment of CO2 geological storage in deep saline aquifers. Furthermore, through cooperation with the China Shenhua Coal to Liquid and Chemical Co., Ltd., we successfully constructed the first coal-based demonstration project for CO2 geological storage in deep saline aquifers in the Yijinhuoluo Banner of Ordos in the Inner Mongolia Autonomous Region, which brought about the basic preliminary theories, techniques, and methods of geological CO2 storage in deep saline aquifers under China's geological conditions. | GUO Jianqiang WEN Dongguang ZHANG Senqi XU Tianfu LI Xufeng DIAO Yujie JIA Xiaofeng | 2015 | Acta Geologica Sinica(English Edition)2015，89，4： | 8 |
| 3 | Relationship between Permian volcanic rocks distribution and karst paleogeomorphology of Maokou Formation and its significance for petroleum exploration in western Sichuan Basin, SW China显示文摘Based on outcrop, drilling, logging, geochemical analysis and seismic data, the karst landform and distribution of Permian volcanic rocks at the end of the sedimentary period of the Maokou Formation in the western Sichuan Basin are examined, and their petroleum geological significance is discussed. Affected by normal faults formed in the early magmatic activities and extension tectonic background in the late sedimentary period of the Maokou Formation, a local karst shallow depression under the background of karst slope came up in the Jianyang area of the western Sichuan Basin, where the residual thickness of the Maokou Formation was thinner. Basic volcanic rocks like pyroclastic rock of eruptive facies, basalt of overflow facies, diabase porphyrite of intrusive facies and sedimentary tuff of volcanic sedimentary facies were formed after karstification. However, under the effects of faulting and karst paleogeomorphology, the volcanic rocks in different areas had different accumulation features. In the Jianyang area, with long eruption time, the volcanic rocks were thick and complex in lithology, and accumulated in the karst depressions. In the Zhongjiang-Santai area located in the karst slope, there’s no fault developed, only thin layers of basalt and sedimentary tuff turned up. The karst landform controls the build-up of thick explosive facies volcanic rocks and also the development of karst reservoirs in the Maokou Formation, and the western Sichuan area has oil and gas exploration potential in volcanic rocks and the Maokou Formation. | LIU Ran LUO Bing LI Ya QIU Nansheng WANG Wei ZHANG Yu HE Qinglin PEI Senqi | 2021 | Petroleum Exploration and Development2021，48，3： | 1 |

| 5 | The COVID-19 Pandemic and Mental Health Concerns on Twitter in the United States显示文摘Background.During the COVID-19 pandemic,mental health concerns(such as fear and loneliness)have been actively discussed on social media.We aim to examine mental health discussions on Twitter during the COVID-19 pandemic in the US and infer the demographic composition of Twitter users who had mental health concerns.Methods.COVID-19-related tweets from March 5th,2020,to January 31st,2021,were collected through Twitter streaming API using keywords(i.e.,“corona,”“covid19,”and“covid”).By further filtering using keywords(i.e.,“depress,”“failure,”and“hopeless”),we extracted mental health-related tweets from the US.Topic modeling using the Latent Dirichlet Allocation model was conducted to monitor users’discussions surrounding mental health concerns.Deep learning algorithms were performed to infer the demographic composition of Twitter users who had mental health concerns during the pandemic.Results.We observed a positive correlation between mental health concerns on Twitter and the COVID-19 pandemic in the US.Topic modeling showed that“stay-at-home,”“death poll,”and“politics and policy”were the most popular topics in COVID-19 mental health tweets.Among Twitter users who had mental health concerns during the pandemic,Males,White,and 30-49 age group people were more likely to express mental health concerns.In addition,Twitter users from the east and west coast had more mental health concerns.Conclusions.The COVID-19 pandemic has a significant impact on mental health concerns on Twitter in the US.Certain groups of people(such as Males and White)were more likely to have mental health concerns during the COVID-19 pandemic. | Senqi Zhang Li Sun Daiwei Zhang Pin Li Yue Liu Ajay Anand Zidian Xie Dongmei Li | 2022 | Health Data Science2022，，1： | 1 |
| 6 | Analyzing the formation cause of Xidatan drinking mineral springs in island permafrost area on north slope of the Kunlun Mountains显示文摘The replenishment source of Xidatan drinking mineral springs in island permafrost area on north slope of the Kunlun Mountains are mainly the melting water from the modern glaciers bottom, snow and ice melting water, atmospheric precipitation, and surface water in Yuzhu Peak area on the Kunlun Mountains. This scenario is based on the survey of hydrogeology, water-conducting and water-controlling faults, and water chemistry, and on the EH-4 high-frequency electronic deep exploration. The original water recharges the deep groundwater at fracture zone of active normal faults F3 and F4 , then groundwater enriches at normal faults F2 and F2-1,2 , and then run northward. A water-rich triangle area is formed when groundwater reach the active reverse fault F1 . Groundwater then discharges through fracture zone of F1 , which is the major cause of the Xidatan mineral springs formation. | SenQi Zhang JiJiao Fan HongTao Wu Fan Jiang LiWei Tan | 2010 | Research in Cold and Arid Regions2010，2，3： | 0 |
