1Cenozoic uplift of the Tibetan Plateau:Evidence from the tectonic-sedimentary evolution of the western Qaidam Basin显示文摘Geologists agree that the collision of the Indian and Asian plates caused uplift of the Tibet Plateau.However,controversy still exists regarding the modes and mechanisms of the Tibetan Plateau uplift.Geology has recorded this uplift well in the Qaidam Basin.This paper analyzes the tectonic and sedimentary evolution of the western Qaidam Basin using sub-surface seismic and drill data. The Cenozoic intensity and history of deformation in the Qaidam Basin have been reconstructed based on the tectonic developments,faults growth index,sedimentary facies variations,and the migration of the depositional depressions.The changes in the sedimentary facies show that lakes in the western Qaidam Basin had gone from inflow to still water deposition to withdrawal.Tectonic movements controlled deposition in various depressions,and the depressions gradually shifted southeastward.In addition,the morphology of the surface structures in the western Qaidam Basin shows that the Cenozoic tectonic movements controlled the evolution of the Basin and divided it into(a) the southern fault terrace zone, (b) a central Yingxiongling orogenic belt,and(c) the northern fold-thrust belt;divided by the XI fault (Youshi fault) and Youbei fault,respectively.The field data indicate that the western Qaidam Basin formed in a Cenozoic compressive tectonic environment caused by the India—Asia plate collision. Further,the Basin experienced two phases of intensive tectonic deformation.The first phase occurred during the Middle Eocene—Early Miocene(Xia Ganchaigou Fm.and Shang Ganchaigou Fm.,43.8—22 Ma),and peaked in the Early Oligocene(Upper Xia Ganchaigou Fm.,31.5 Ma).The second phase occurred between the Middle Miocene and the Present(Shang Youshashan Fm.and Qigequan Fm., 14.9—0 Ma),and was stronger than the first phase.The tectonic—sedimentary evolution and the orientation of surface structures in the western Qaidam Basin resulted from the Tibetan Plateau uplift,and recorded the periodic northward growth of the Plateau.Recognizing this early tectonic—sedimentary evolution supports the previous conclusion that northern Tibet responded to the collision between India and Asia shortly after its initiation.However,the current results reveal that northern Tibet also experienced another phase of uplift during the late Neogene.The effects of these two stages of tectonic activity combined to produce the current Tibetan Plateau.Yadong Wang Jianjing Zheng Weilin Zhang Shiyuan Li Xingwang Liu Xin Yang Yuhu Liu 2012Geoscience Frontiers2012,3,2:23
2First mass measurement of short-lived nuclides at HIRFL-CSR显示文摘Recent commissioning of the HIRFL-CSR has demonstrated its ability to perform direct mass measurement for short-lived nuclides. Projectile fragments produced by the 78Kr ions at 481.88 MeV/u were separated with the new radioactive beam line in Lanzhou (RIBLL2), and injected into and stored in the experimental storage ring (CSRe). By operating the CSRe as an isochronous mass spectrometry, a typical mass resolution around 2.0×10?5 has been achieved. The masses for 63Ge, 65As and 67Se were measured for the first time. The measured masses are compared with theoretical predictions and the location of the proton drip-line for As isotopes is discussed. The implication of the 65As mass in the astrophysical rapid proton capture process has also been addressed.XU HuShan TU XiaoLin YUAN YouJin XIA JiaWen ZANG YongDong WANG Meng MAO RuiShi HU ZhengGuo MEI Bo SHUAI Peng ZHU ZhiChao TANG ShuWen GENG Peng LIU Yong ZHAO TieCheng ZHANG XueYing YANG JianCheng MAO LiJun ZHANG YuHu ZHOU XiaoHong HUANG WenXue XIAO GuoQing ZHAO HongWei ZHAN WenLong 2009Chinese Science Bulletin2009,54,24:11
3Clearance Influence on Dynamic Response of Intermittent Roller Chain Drive显示文摘The clearances appear in chain link hinges induced by manufacturing tolerance or wear of components are the most important factor that influences the dynamic performance of the intermittent roller chain drives.Due to the existence of the clearances in chain link hinges,the serious impact vibration phenomenon which influences the stability and the position accuracy of the chain drive system would be caused in the intermittent motion.But,the problem may be that a reasonable modeling on the chain with clearances is difficult due to the large clearance's number in chain system and the fact that the clearance' size are different.Currently,the studies on the dynamics of the intermittent roller chain considering the multi-clearance' joints are rare.Most research works have only focused on the constant moving chains.Taking the intermittent roller chain system as an object,this paper designs and builds the experimental device of this kind of mechanical system.The Longitudinal vibration response of the intermittent chain under the different motion laws was tested.The experimental study shows that the clearances presented in chain link hinges can cause severe impact vibration in the intermittent motion of chain.In subsequent work,the dynamic model of the intermittent roller chain system with the multi-clearance' joints was established.By calculating the dynamic response of this kind of mechanical system under the different motion laws,the effect of the clearances on the dynamic response of the intermittent chain drive system was analyzed.The theoretical simulation shows that the serious impact vibration phenomenon of the chain system can be caused by the clearances at the start accelerating period,and the chain drive system is often accompanied by the severe shock and vibration at the moment that the chain moves from the acceleration period to deceleration period.The research conclusions made by the experimental and theoretical studies indicate that the use of motion laws with small and continuous jerk at conversion point can effectively suppress the impact vibration at this point caused by clearances' effect.Additionally,the use of nonsymmetrical motion laws with small jerk approaching the end of the indexing period can obtain a smaller residual vibration.The presented motion law can provide an important reference for the improvement of the dynamic performance of the intermittent chain drive systems.XU Lixin YANG Yuhu CHANG Zongyu SHEN Zhaoguang LIU Jianping 2010Chinese Journal of Mechanical Engineering2010,23,6:11
4Tectonic Evolution of the Tianhuan Depression and the Western Margin of the Late Triassic Ordos显示文摘The Ordos Basin is one of the most important oil and gas basins in China. Based on surface outcrop, key exploratory wells and seismic reflection data and by using the technology of 'prototype basin recovery', seismic profile 'layer flattening' and 'restoration of balanced section',and other methods, the sedimentary boundary, structure and the evolution history of the Tianhuan depression on the western margin of the Ordos Basin are reestablished. The following results have been obtained. (1) The west boundary of the Late Triassic Ordos Basin was far beyond the scope of the current basin. The basin is connected with the Late Triassic Hexi Corridor Basin, and its western margin did not have tectonic characteristics of a foreland basin. (2) The Tianhuan depression was first formed in the Late Jurassic. At the late stage it was impacted by the late Yanshanian and Himalayan tectonic movement and the depression axis gradually moved eastwards to the present location with a cumulative migration distance of ~30 km. (3) Eastward migration of the depression axis caused adjustment and even destruction of the originally formed oil and gas reservoirs, so that oil and gas remigrated and aggregated, resulting in secondary structural reservoirs formed at high positions on the western flank of the depression.LI Xiangbo LIU Huaqing WANYAN Rong WEI Lihua LIAO Jianbo FENG Ming MA Yuhu BAI Yunlai 2009Acta Geologica Sinica(English Edition)2009,83,6:9
5Properties of Continental Margin and its Hydrocarbon Exploration Significance in Cambrian in the Southern Ordos Kratogen of North China显示文摘It is important to determine the properties of the tectonics in Cambrian period for the sake of prospecting deep hydrocarbon in the near future in the southern Ordos Kratogen of North China. Authors chose the marginal areas of the southern Ordos basin as the object of research, avoided the effects of both the Qinling Orogenic Belts (QOB) and Weihe River Graben (WRG) whose geological structures are too complicated. By surveying typical Cambrian outcrops and profiles in the basin edges and based on the cores of 57 wells which penetrated the Cambrian in the basin, combined with the seismic profiles, the field gammaray measuement results and the carbon isotope analysis, Authors conclude that the southern margin of the Ordos Kratogen during Cambrian was a passive continental margin which resulted from sea-floor spreading of the Ancient Qinling Ocean. Epicontinental sea carbonate sediments formed in the south Ordos continental margin during Cambrian, and were predominant as tidal flat and o litic shoal. Both transgression-regression process and the change in palaeostructure have the obvious cyclicity. Using the junction between the late Nangao age of Qiandong epoch and the early Duyun age of Qiandong epoch as a boundary, each had a full transgression cycle at the upper and lower stages. The early cycle is characterized by high energy clastic littoral facies while the late cycle is characterized by carbonate ramp on which clear water and muddy water developed alternately changing to carbonate platform last. During the early stages, An aulacogen was formed in the middle section of the southern margin. The southern Ordos margin was uplifted and denudated by the Huaiyuan Movement which occurred from the late Furongian age to the middle Flolan age and the history of the passive continental margin ended and entering into a new tectonic cycle. The unconformity surface caused by the Huaiyuan Movement, along with its neighborhood areas where dissolved pores and cavities are developed, may be another important district for good hydrocarbon reservoirs (excluding the unconformity surface on the top of the Ordovician in the Ordos basin).BAI Yunlai MA Yuhu HUANG Yong LIAO Jianbo LIU Xiaoguang 2013Acta Geologica Sinica(English Edition)2013,87,3:9
6Similarity theory for the physical simulation of natural gas hydrate reservoir development显示文摘In order to apply physical simulation results to natural gas hydrate reservoir parameters to provide a theoretical framework for the design of a development plan,an analytical equation method was used to obtain the similarity criteria of natural gas hydrate reservoir development by physical simulation,based on a mathematical model of natural gas hydrate development.Given the approach of numerical simulation,a sensitivity analysis for all parameters was carried out,which specifically demonstrated that initial temperature is the most important parameter.Parameters of thermal conductivity coefficients are not necessary for conducting the NGH dissociation process,which will fundamentally simplify the design and establishment of the model.The analysis provides a sound theoretical basis and design principles for particular similarity.LIU Yaping CHEN Yueming BAI Yuhu LI Shuxia 2010Mining Science and Technology2010,20,5:7
7An Examination of the Predictability of Tropical Cyclone Genesis in High-Resolution Coupled Models with Dynamically Downscaled Coupled Data Assimilation Initialization显示文摘Predicting tropical cyclone(TC)genesis is of great societal importance but scientifically challenging.It requires fineresolution coupled models that properly represent air−sea interactions in the atmospheric responses to local warm sea surface temperatures and feedbacks,with aid from coherent coupled initialization.This study uses three sets of highresolution regional coupled models(RCMs)covering the Asia−Pacific(AP)region initialized with local observations and dynamically downscaled coupled data assimilation to evaluate the predictability of TC genesis in the West Pacific.The APRCMs consist of three sets of high-resolution configurations of the Weather Research and Forecasting−Regional Ocean Model System(WRF-ROMS):27-km WRF with 9-km ROMS,and 9-km WRF with 3-km ROMS.In this study,a 9-km WRF with 9-km ROMS coupled model system is also used in a case test for the predictability of TC genesis.Since the local sea surface temperatures and wind shear conditions that favor TC formation are better resolved,the enhanced-resolution coupled model tends to improve the predictability of TC genesis,which could be further improved by improving planetary boundary layer physics,thus resolving better air−sea and air−land interactions.Mingkui LI Shaoqing ZHANG Lixin WU Xiaopei LIN Ping CHANG Gohkan DANABASOGLU Zhiqiang WEI Xiaolin YU Huiqin HU Xiaohui MA Weiwei MA Haoran ZHAO Dongning JIA Xin LIU Kai MAO Youwei MA Yingjing JIANG Xue WANG Guangliang LIU Yuhu CHEN 2020Advances in Atmospheric Sciences2020,37,9:4

13Supervised Penalty Matrix Decomposition for Tumor Differentially Expressed Genes Selection显示文摘A reliable and precise recognition of the differentially expressed genes of tumor is crucial to treat the cancer effectively. The small number of differentially expressed genes in a huge gene expression dataset determines the important role of sparse methods, such as Penalty matrix decomposition(PMD), among the feature selection methods. The sparse methods always have the drawback: they do not take advantage of known class labels of gene expression data. A novel supervised-sparse method named as Supervised PMD(SPMD) is proposed by adding the class information into PMD via the total scatter matrix. The brief idea of our method used to select the differentially expressed genes is given as follows.The total scatter matrix is obtained according to the gene expression data with class label. The obtained total scatter matrix is decomposed by PMD to acquire the sparse vectors. The non-zero items in sparse vectors are selected as the differentially expressed genes. The Gene ontology(GO) enrichment of functional annotation of the selected genes is detected by Topp Fun. Experiments on synthetic data and two real tumor gene expression datasets show that the proposed SPMD is quite promising to select the differentially expressed genes.LIU Jian CHENG Yuhu WANG Xuesong CUI Xiaoluo 2018Chinese Journal of Electronics2018,27,4:1

19Recommendations for the diagnosis and treatment of paroxysmal kinesigemc dyskinesia: an expert consensus in China显示文摘Paroxysmal dyskinesias are a group of neurological diseases characterized by intermittent episodes of involuntary movements with different causes.Paroxysmal kinesigenic dyskinesia(PKD)is the most common type of paroxysmal dyskinesia and can be divided into primary and secondary types based on the etiology.Clinically,PKD is characterized by recurrent and transient attacks of involuntary movements precipitated by a sudden voluntary action.The major cause of primary PKD is genetic abnormalities,and the inheritance pattern of PKD is mainly autosomal-dominant with incomplete penetrance.The proline-rich transmembrane protein 2(PRRT2)was the first identified causative gene of PKD,accounting for the majority of PKD cases worldwide.An increasing number of studies has revealed the clinical and genetic characteristics,as well as the underlying mechanisms of PKD.By seeking the views of domestic experts,we propose an expert consensus regarding the diagnosis and treatment of PKD to help establish standardized clinical evaluation and therapies for PKD.In this consensus,we review the clinical manifestations,etiology,clinical diagnostic criteria and therapeutic recommendations for PKD,and results of genetic analyses in PKD patients performed in domestic hospitals.Li Cao Xiaojun Huang Ning Wang Zhiying Wu Cheng Zhang Weihong Gu Shuyan Cong Jianhua Ma Ling Wei Yanchun Deng Qi Fang Qi Niu Jin Wang Zhaoxia Wang You Yin Jinyong Tian Shufen Tian Hongyan Bi Hong Jiang Xiaorong Liu Yang Lu Meizhen Sun Jianjun Wu Erhe Xu Tao Chen Tao Chen Xu Chen Wei Li Shujian Li Qinghua Li Xiaonan Song Ying Tang Ping Yang Yun Yang Min Zhang Xiong Zhang Yuhu Zhang Ruxu Zhang Yi Ouyang Jintai Yu Quanzhong Hu Qing Ke Yuanrong Yao Zhe Zhao Xiuhe Zhao Guohua Zhao Furu Liang Nan Cheng Jianhong Han Rong Peng Shengdi Chen Beisha Tang 2021Translational Neurodegeneration2021,10,1:1
