1边界层流场和地形特征对青岛奥帆赛场午后海风影响的研究显示文摘奥帆赛是奥运会唯一以自然风为动力的竞赛项目,而北京奥运会期间的8月,青岛的风速是一年中最小的,因风速过小致使帆船竞赛地法进行的情况时有发生。鉴于青岛的弱风与海陆风的发展状况关系密切,文中分析8、9月青岛奥帆赛和残奥帆赛期间竞赛海域海陆风的发展条件,并用高分辨率数值模式对相关个例进行了模拟试验研究。结果发现,地面背景气流、边界层中上部径向气流和周围地形、海陆分布等边界层特征,都对竞赛海域海陆风的发展产生影响。其中晴天时,地面西风、弱的北风和东风、均压场环境以及边界层中上部弱的北风条件等,都是竞赛海域海风发展的有利条件;而地面南风(无论大小)、强的北风以及边界层中上部较强的南风和很强的北风等,则是海风发展的不利条件。此外,当地面为东北风时,位于竞赛海域上游的崂山对地面风速有阻挡减弱的作用,从而有利于海风的发展;地面为南风时,崂山和浮山等地形强迫气流在竞赛海域附近向左右分为两支,胶州湾和崂山湾侧向海风(东南风)急流发展又加大了这种分流作用,导致竞赛海域常减小为弱风,使比赛无法进行。以上结论在2008年奥帆赛和残奥帆赛气象保障预报服务中得到运用。李庆宝 苗世光 刘学刚 张苏平 孙桂平 LIU Xiaochu 2010气象学报2010,68,6:11
2Altered Resting-State Signals in Patients with Acute Stroke In or Under the Thalamus显示文摘Previous studies have suggested that cortical functional reorganization is associated with motor recovery after stroke and that normal afferent sensory information is very important in that process.In this study,we selected patients who had a stroke in or under the thalamus,with potentially impaired afferent sensory information and analyzed the differences between these patients and healthy controls at three levels:brain regions,the functional connectivity between brain areas,and the whole-brain functional network.Compared with healthy controls,regional homogeneities in the left middle temporal gyrus decreased and functional connectivity between the left middle temporal gyrus and the stroke area increased in the patients.However,there was no significant change in the wholebrain functional network.By focusing on stroke located in or under the thalamus,our study contributes to wider inquiries into understanding and treating stroke.Lijun Chen Chuanfu Li Jian Zhai Anqin Wang Qin Song Ying Liu Ru Ma Long Han Yamikani Ndasaukas Xiaoming Li Hai Li Xiaochu Zhang 2016Neuroscience Bulletin2016,32,6:6
3青岛奥帆赛场不同背景条件下的海陆风特征显示文摘对青岛奥帆赛竞赛海域不同背景条件下的海陆风进行分析,并用高分辨率数值模式进行了模拟实验。结果发现,不同背景气流,海风的发展状况有很大差异。均压场、西向气流、弱的东向气流都有利于海陆风的发展;南向气流最不利于海风的发展;北向气流虽有利于海陆风发展,但海风强度取决于背景气流强度:气流越弱,海风越强。700~1500m高空为不太强的北风时有利于海风环流的生成;因与补偿回流反向,较强的南风则会严重抑制海风环流的发展。胶州湾和崂山东侧强南风轴会迫使气流在奥帆赛场附近分支而使风速明显减小;太平山、浮山等的阻滞作用也会使该区域气流减速。有利于奥帆赛场海风发展的条件是:(1)晴天,适当的海陆温差;(2)较小的地面气压梯度;(3)700~1500m平均经向风为不太强的北风;(4)地面图上的地转风为非南向等。实践表明:以上分析结果,都对奥帆赛场风的预报有重要的参考意义。李庆宝 苗世光 孙桂平 张苏平 刘学刚 Liu Xiaochu 2008气象2008,34,S1:6
4Study on Volatile Oil Components and Total Anti-oxidation Capacity and Simulated SOD Activity of Leaves from Michelia chapensis and M. fovelata显示文摘The volatile oils from leaves of Michelia chapensis Dandy and M. foveolata Merr.ex Dandy were isolated by organic solvent extraction and their components were analyzed and quantified by GC/MS. Then, the total anti-oxidation capacity and simulated SOD activity were tested. Forty-four compounds in M. chapensis were identified and the main constituents are aromatic (11.057%), ester (5.041%) and terpenoid compounds (19.772%). Fifty-two compounds in M. foveolata were identified, and their main constituents are aromatic (21.293%), alcohol (17.403%), alkene (6.909%), ester (5.657%) and alkane compounds (5.134%). The results showed that the two oils have strong anti-oxidation capacity and simulated SOD activity. The total anti-oxidation capacities were the highest when the volatile oil from M. foveolata was diluted by 50 times and that from M.chapensis by 100 times. The simulated SOD activity of volatile oil from M. chapensis was higher than that from M. foveolata, and CuZn-SODs in the two oils held 73%-74% of the total SOD. These results will provide scientific foundation for the exploration of the bioactivity of M. chapensis and M. foveolata.HE Kaiyue ZHANG Shuangquan LI Xiaochu FAN Yasu LI Baocun 2006Chinese Forestry Science and Technology2006,5,3:3
5Non-invasive Brain Stimulation for the Treatment of Nicotine Addiction:Potential and Challenges显示文摘Tobacco consumption is one of the leading causes of preventable death worldwide.However,it is difficult to give up smoking by relying on the help of traditional treatments only.Recent years have witnessed emerging positive evidence that non-invasive brain stimulation(NIBS),such as transcranial magnetic stimulation and transcranial direct-current stimulation,can reduce smoking-related behaviors.Although their potential has been implied by advances in research,several methodological issues restrict the clinical application of NIBS to treating nicotine dependence.In this review,we critically evaluate related studies and give suggestions for future research and applications to meet these challenges.Li-Zhuang Yang Zhiyu Yang Xiaochu Zhang 2016Neuroscience Bulletin2016,32,6:3

10Impulsivity-related right superior frontal gyrus as a biomarker of internet gaming disorder显示文摘Background Internet gaming disorder(IGD)is a mental health issue that affects individuals worldwide.However,the lack of knowledge about the biomarkers associated with the development of IGD has restricted the diagnosis and treatment of this disorder.Aims We aimed to reveal the biomarkers associated with the development of IGD through resting-state brain network analysis and provide clues for the diagnosis and treatment of IGD.Methods Twenty-six patients with IGD,23 excessive internet game users(EIUs)who recurrently played internet games but were not diagnosed with IGD and 29 healthy controls(HCs)performed delay discounting task(DDT)and Iowa gambling task(IGT).Resting-state functional magnetic resonance imaging(fMRI)data were also collected.Results Patients with IGD exhibited significantly lower hubness in the right medial orbital part of the superior frontal gyrus(ORBsupmed)than both the EIU and the HC groups.Additionally,the hubness of the right ORBsupmed was found to be positively correlated with the highest excessive internet gaming degree during the past year in the EIU group but not the IGD group;this might be the protective mechanism that prevents EIUs from becoming addicted to internet games.Moreover,the hubness of the right ORBsupmed was found to be related to the treatment outcome of patients with IGD,with higher hubness of this region indicating better recovery when undergoing forced abstinence.Further modelling analysis of the DDT and IGT showed that patients with IGD displayed higher impulsivity during the decision-making process,and impulsivity-related parameters were negatively correlated with the hubness of right ORBsupmed.Conclusions Our findings revealed that the impulsivity-related right ORBsupmed hubness could serve as a potential biomarker of IGD and provide clues for the diagnosis and treatment of IGD.Pengyu Zhang Yu Pan Rujing Zha Hongwen Song Cunfeng Yuan Qian Zhao Yi Piao Jiecheng Ren Yijun Chen Peipeng Liang Ran Tao Zhengde Wei Xiaochu Zhang 2023General Psychiatry2023,36,4:1

13Does Property Rights Reform Improve the Efficiency of China's State-owned Banks?显示文摘China's state-owned banks have undergone radical changes over the past two decades,including partial privatization and listing in both the Hong Kong Stock Exchange and the Shanghai Stock Exchange.This paper evaluates the effects of these changes by analyzing the efficiency of Chinese banks over the period 1998-2012 using two frontier techniques and comparative analysis.The findings suggest that the performance and technical efficiency of the Big Four banks improved considerably after property rights reform,but this improvement is not sufficient to keep the banks at the production frontier.Tobit regressions confirm that static ownership effects are negative but that the property rights reform has had significant and positive effects on the technical efficiency of state-owned commercial banks.GDP growth and the financial crisis have had positive effects on the efficiency of Chinese banks,which is more significant for joint stock commercial banks than state-owned commercial banks.The results indicate the value of ownership reforms of state-owned asset management companies and insurance companies and the establishment of a countercyclical capital buffer.Qian Wang Xiaochu Feng 2014China & World Economy2014,22,4:1
