4Multi-View & Transfer Learning for Epilepsy Recognition Based on EEG Signals显示文摘Epilepsy is a central nervous system disorder in which brain activity becomes abnormal.Electroencephalogram(EEG)signals,as recordings of brain activity,have been widely used for epilepsy recognition.To study epilep-tic EEG signals and develop artificial intelligence(AI)-assist recognition,a multi-view transfer learning(MVTL-LSR)algorithm based on least squares regression is proposed in this study.Compared with most existing multi-view transfer learning algorithms,MVTL-LSR has two merits:(1)Since traditional transfer learning algorithms leverage knowledge from different sources,which poses a significant risk to data privacy.Therefore,we develop a knowledge transfer mechanism that can protect the security of source domain data while guaranteeing performance.(2)When utilizing multi-view data,we embed view weighting and manifold regularization into the transfer framework to measure the views’strengths and weaknesses and improve generalization ability.In the experimental studies,12 different simulated multi-view&transfer scenarios are constructed from epileptic EEG signals licensed and provided by the Uni-versity of Bonn,Germany.Extensive experimental results show that MVTL-LSR outperforms baselines.The source code will be available on http://gffzz188fe103f8f1460asq0uuk5xqc6vv60cq.ffgz.tsg.suse.edu.cn/didid5/MVTL-LSR.Jiali Wang Bing Li Chengyu Qiu Xinyun Zhang Yuting Cheng Peihua Wang Ta Zhou Hong Ge Yuanpeng Zhang Jing Cai 2023Computers, Materials & Continua2023,,6:0
5Application of Tobacco Leaves from Shandong in ' Taishan' Brand显示文摘In view of the fact that the proportion of tobacco leaves from Shandong in the stocks of a company is large,based on the premise of not affecting the quality of cigarettes,through the scientific evaluation,selection and matching test,the proportion of tobacco leaves from Shandong in the formula of ' Taishan' cigarette A has been increased,and the sensory quality of ' Taishan' cigarette A before and after the test is basically stable.Moreover,the stocks of tobacco leaves from Shandong can be decreased in time.Chengyu QIU Xiansheng ZHOU Cuishu LENG Shoujie NIE Guangyu MENG 2018Agricultural Biotechnology2018,7,6:0
6Paleo-oil reservoir pyrolysis and gas release in the Yangtze Block imply an alternative mechanism for the Late Permian Crisis显示文摘The causes of the global mass extinction that occurred around the Permian-Triassic boundary have been widely studied through the geological record and in various locations.The results show that volcanic activity was a key factor in initiating the crisis during the Late Permian.Compared to other thermal events triggered by volcanic activity,pyrolysis of petroleum in Pre-Permian reservoirs has rarely been suggested as a significant source of the greenhouse gases that caused the mass extinction.In this study,geochemical analysis is carried out of a huge paleo-oil reservoir in the Yangtze Block(YB),South China.The detection of mineral inclusions and pyrobitumens is evidence of rapid pyrolysis of accumulated oil in the Ediacaran reservoir.New evidence from hydrothermal minerals and the presence of domain mesophase in the pyrobitumen suggest that the pyrolysis process occurred abruptly and that greenhouse gases were rapidly released through venting pipes.The dating of such a complex geological event in this old and deeply buried reservoir is inevitably difficult and potentially unreliable.However,cross-validation of the multiple evidence sources,including hydrothermal minerals and domain mesophase,indicates that the rapid oil pyrolysis must have been driven by a major thermal event.Reconstruction of burial and thermal histories suggests that the thermal event was most likely to have been triggered by the Emeishan Large Igneous Province(ELIP),which was in a period of significant volcanic activity during the Late Permian.Massive volumes of gases,including methane,carbon dioxide,and possibly hydrogen sulfide,were released,causing a significant increase in greenhouse gases that may have contributed to global warming and the resulting mass extinction during the Late Permian Crisis(LPC).Chengyu Yang Meijun Li Zhiyong Ni Tieguan Wang Nansheng Qiu Ronghui Fang Long Wen 2022Geoscience Frontiers2022,13,2:0
