1First observation of mesospheric and thermospheric winds by a Fabry-Perot interferometer in China显示文摘A Fabry-Perot interferometer,funded by the Meridian Project in China,was deployed at the Xinglong station(40.2°N,117.4°E) of the National Astronomical Observatories in Hebei Province,China.The instrument has been operating since April 2010,measuring mesospheric and thermospheric winds.The first observational data of winds at three heights in the mesosphere and thermosphere were analyzed,demonstrating the capacity of this instrument to aid basic scientific research.The wavelengths of three airglow emissions were OH892.0,OI 557.7,and OI 630.0 nm,which corresponded to heights of 87,98,and 250 km,respectively.Three 38-day data sets of horizontal winds,from April 5,2010 to May 12,2010,show clear day-to-day variations at the same height.The minimum and maximum meridional winds at heights of 87,98,and 250 km were-16.5 to 8.7 m/s,-24.4 to 15.9 m/s,and-43.6 to 1.5 m/s.Measurements of zonal winds were-5.4 to 7.6 m/s,2.3 to 23.0 m/s,and-22.6 to 49.3 m/s.The average data from the observations was consistent with the data from HWM93.The wind data at heights of 87 and 98 km suggest a semi-diurnal oscillation,clearly consistent with HWM93 results.Conversely there was a clear discrepancy between the observations and the model at 250 km.In general,this Fabry-Perot interferometer is a useful ground-based instrument for measuring mesospheric and thermospheric winds at middle latitudes.YUAN Wei XU JiYao MA RuiPing WU Qian JIANG GuoYing GAO Hong LIU Xiao CHEN SunZheng 2010Chinese Science Bulletin2010,55,35:18
2A comparison of mesospheric winds measured by FPI and meteor radar located at 40N显示文摘In this paper, winds derived from OH Meinel 892.0 nm detection by an FPI (Fabry-Perot Interferometer) are compared with the simultaneous wind measurements from a meteor radar during April-May of 2010. The peak height of OH Meinel 892.0 nm is about 87 km. The variations of FPI wind at 87 km mostly have the similar track to meteor radar wind at 87 km, and the data values of FPI wind mainly fall into the range of meteor radar wind. However, there are still quantitative differences between the observations of the two systems. The best cross-correlation occurs in meridional winds from two systems in April of 2010. An obvious wave signal with 0.2 cycle/d frequency is found in meridional winds observed by both FPI and meteor radar.JIANG GuoYing XU JiYao YUAN Wei NING BaiQi WAN WeiXing HU LianHuan 2012Science China(Technological Sciences)2012,55,5:12
3Observations of the first meteorological rocket of the Meridian Space Weather Monitoring Project显示文摘On June 3,2010,the first meteorological rocket of the Meridian Space Weather Monitoring Project was successfully launched at the Hainan rocket launch site(19.5°N),China.This paper analyzes the vertical profiles of atmospheric temperature and wind recorded by the rocket and its supportive balloons,and investigates wind shear,gravity waves and atmospheric stability.In addition,we compare the vertical profiles of atmospheric temperature and wind with SABER/TIMED temperature measurements and the modeling results of MSIS00 and HWM07.JIANG GuoYing XU JiYao SHI DongBo WEI Feng WANG LianZhong 2011Chinese Science Bulletin2011,56,20:9
4Construction of a genetic map and location of quantitative trait loci for dwarf trait in maize by RFLP markers显示文摘Using F2 population derived from the cross of tall inbred 7922 by dwarf inbred 5003, an RFLP linkage map of maize has been constructed, on which 85 markers are distributed among 10 linkage groups and span maize genome about 1827.8 cM with an average distance (24.4 cM) between markers. 106 F2:3 lines of the population were grown in a 10×11 simple rectangular lattice design of one-raw plots with two replications and evaluated for plant height (PH). With interval mapping procedure, 5 QTLs controlling plant height have been identified and their genetic effects and gene action determined. 2 major OTLs with opposite effect have been discovered. One for increasing plant height is ph 1 which is located at chromosome 2 and accounts for 51.8% of the total phenotypic variation; the other for decreasing plant height is ph3 which is located at chromosome 5 and accounts for 38.6% of the total phenotypic variation. The chromosomal location of ph3 might be the same as or close to the position of bv1, a dwarf mutantCAO Yongguo WANG Guoying WANG Shoucai WEI Yanling LU Jiang XIE Youju DAI Jingrui 2000Chinese Science Bulletin2000,45,3:9
5A novel procedure for pollen-based quantitative paleoclimate reconstructions and its application in China显示文摘Traditionally, the evaluation of pollen-based quantitative paleoclimate reconstructions focuses on the ability of calibration sets to infer present climatic conditions and/or the similarity between fossil and modern assemblages. Objective criteria for choosing the most appropriate climate parameter(s) to be reconstructed at a specific site are thus lacking. Using a novel approach for testing the statistical significance of a quantitative reconstruction using random environmental data, in combination with the advantageous large environmental gradients, abundant vegetation types and comprehensive modern pollen databases in China, we describe a new procedure for pollen-based quantitative paleoclimatic reconstructions. First, the most significant environmental variable controlling the fossil pollen assemblage changes is identified. Second, a calibration set to infer changes in this targeted variable is built up, by limiting the modern ranges of other environmental variables. Finally, the pollen-based quantitative reconstruction is obtained and its statistical significance assessed. This novel procedure was used to reconstruct the mean annual precipitation(Pann) from Gonghai Lake in the Lvliang Mountains, and Tianchi Lake in the Liupan Mountains, on the eastern and western fringe of the Chinese Loess Plateau, respectively. Both Pann reconstructions are statistically significant(p<0.001), and a sound and stable correlation relationship exists in their common period, showing a rapid precipitation decrease since 3300 cal yr BP. Thus, we propose that this procedure has great potential for reducing the uncertainties associated with pollen-based quantitative paleoclimatic reconstructions in China.CHEN JianHui LV FeiYa HUANG XiaoZhong H.John B.BIRKS Richard J.TELFORD ZHANG ShengRui XU QingHai ZHAO Yan WANG HaiPeng ZHOU AiFeng HUANG Wei LIU JianBao WEI GuoYing 2017Science China Earth Sciences2017,60,11:6
6Magnetic performance and corrosion resistance of electroless plating CoWP film显示文摘The CoWP film with good magnetic performance and corrosion resistance was electrolessly plated from alkaline solution. The technical parameters of the electroless plating system were optimized. When the pH value of electroless plating solution was 11.0 and the reducing agent (NaH2PO2) content was 0.4 mol L 1, the target chemical reactions proceeded in the electroless plating solution smoothly with negligible interference and side effects. CoWP film prepared under optimal deposition condition contained more hexagonal close-packed (hcp) cobalt (ε-Co) of [110] and crystallographic orientation of Co [002]. VSM analysis reveals that the saturation magnetization of the CoWP film is 100~220 Am2 kg 1 and coercivity is (2.87~4.38)×104 A·cm 1. The corrosion behavior of CoWP film in 3.5% NaCl aqueous solution was studied by electrochemical experiments. The results prove that the corrosion resistance of the CoWP film deposited under the optimal depo-sition condition exhibites relatively lower corrosion current of (3.054~3.162)×10 6 A·cm 2. The surface morphology analysis indicates that the film is smooth and composed of regular-shaped crystallites.Jiang, Li Pan, Shanshan Lu, Jianbiao Ke, Xin He, Wenhao Yu, Yundan Wei, Guoying Ge, Hongliang 2012Rare Metals2012,31,3:6
7Gait analysis of goat at different slopes and study on biomimetic walking mechanism显示文摘To study the walking status of a goat on slope and the walking mechanics,a comparative analysis of the walking gait mode of a goat on different slopes was conducted.The uphill and downhill walking processes on different slopes(6°,18°and 36°)were recorded by a high speed video system.The experimental image results were processed and analyzed via SigmaScan software and MATLAB software.The characteristic parameters of locomotion gait on the different slopes and the angle change curves of each goat leg in the process of slope movement indicated that the goat performed tetrapod gait,static gait,ipsilateral gait and trot gait on different slopes.With the increase of gradient in the uphill process,the corresponding load factors of each leg were 0.65±0.15,0.75 and 0.645±0.205,whereas those in the downhill process were 0.70±0.08,0.66±0.06,and 0.685±0.125.Results showed that the load factors of each leg are higher than 0.5.The foreleg angle ofa(the angle of wrist joints),which ranges from 100°to 130°,is suitable for different slopes.However,the angle ofb(the angle between the thigh and the forward direction in the walking process of goat),which ranges from 99°to 109°,is suitable for the 6°slope,whereas the angle ranging from 46°to 91°is suitable for the 18°slope and 36°slope.For the hind leg,the angle ofa,which ranges from 105°to 153°,is suitable for the different slopes.The angle ofb,which ranges from 128°to 150°,is suitable for the different slopes.The research can provide a theoretical basis and experimental data for the design of biomimetic agricultural slope walking mechanism.Zhang Fu Wang Wei Zhang Guoying Wang Jun Qiu Zhaomei Mao Pengjun 2016International Journal of Agricultural and Biological Engineering2016,9,3:6

11Virus-induced silencing of a tobacco deoxyhypusine synthase gene显示文摘A cDNA fragment corresponding to deoxyhy-pusine synthase gene NbDHS was isolated and cloned into potato virus X (PVX) vector for functional analysis in Nico-tiana benthamiana by using virus-induced gene silencing (VIGS). Plants agroinfected with recombinant virus vector PVX-NbDHS exhibited an increase in leaf biomass, delay in natural leaf senescence and flowering time, and decrease in leaf chlorophyll content. Semi-quantitative RT-PCR and Northern analysis showed that the transcript level of DHS was significantly lower in PVX-NbDHS infected plants. At the same time, the expression for eIF-5A, the target proteins of DHS in N. benthamiana, was concomitantly suppressed by semi-quantitative RT-PCR and Western analysis. From the phenotypic feature of the infected plants and the reduced expression abundance of DHS and eIF-5A, we concluded that NbDHS plays important roles in plant growth, development and senescence. The possible application of DHS gene in ge-netic modification of crops and horticultural plants was dis-cussed.WANG Hongzhi MA Rongcai LI Ruifen WANG Guoying WEI Jianhua 2005Chinese Science Bulletin2005,50,23:2
12Preparation of CoP films by ultrasonic electroless deposition at low initial temperature显示文摘Electroless deposition technology has been considered as a kind of common ways to obtain cobalt alloy films. However, in order to get cobalt alloy films, high temperature(353 K) is necessary during the electroless deposition process which will increase costs and energy consumption. Ultrasonic was introduced during electroless plating process to obtain cobalt alloy films at lower initial temperature. It was found that the cobalt thin films could be prepared at lower initial temperature(323 K) with the introduction of ultrasonic. Therefore, different powers of ultrasonic were applied during the electroless deposition process to prepare CoP thin films on copper substrates from an alkaline bath in this investigation. The effects of different powers of ultrasonic on deposition rate, surface morphology, anticorrosion performance and magnetic property of films were studied. It was found that the deposition rate increased gradually with the rise in ultrasonic powers due to cavitation phenomenon. All the CoP films presented the typical spherical nodular structures with the impact of ultrasonic. Smaller and regular shaped structures could be observed when the films were deposited with higher power of ultrasonic which contributed directly to enhancement of anticorrosion performance. Saturation magnetization and coercivity of thin films increased gradually with the rise in ultrasonic powers during the electroless deposition process due to the higher amounts of cobalt.& 2014 Chinese Materials Research Society.

18Prognostic Role and Potential Mechanisms of N6-methyladenosine-related Long Noncoding RNAs in Hepatocellular Carcinoma显示文摘Background and Aims:Numerous studies have explored the important role of N6-methyladenosine(m^(6)A)in cancer.Nonetheless,the interaction between m^(6)A and long noncoding RNAs(lncRNAs)is poorly investigated.Herein,we systematically analyzed the role and prognostic value of m^(6)A-related lncRNAs in hepatocellular carcinoma(HCC).Methods:The m^(6)A-related lncRNAs were identified based on the correlation coefficients with m^(6)A-related genes in HCC from The Cancer Genome Atlas.Subsequently,a novel risk score model was determined using the least absolute shrinkage and selection operator Cox regression analyses.Univariate and multivariate Cox analyses were used to identify independent prog-nostic factors for overall survival(OS)of HCC;thereafter,a prognostic nomogram was constructed.Results:A total of 259 lncRNAs showed significant correlations with m^(6)A in HCC,while 29 lncRNAs had prognostic significance.Further,six critical m^(6)A-related lncRNAs(NRAV,SNHG3,KDM4A-AS1,AC074117.1,AC025176.1,and AL031985.3)were screened out to construct a novel risk score model which classified HCC patients into high-and low-risk groups.Survival analy-ses revealed that patients in the high-risk group exhibited worse OS,both in the training and validation groups.The risk score was also identified as an independent prognostic factor of OS,and a nomogram was established and verified with superior prediction capacity.Besides,the risk score signifi-cantly correlated with the expression of immune checkpoint genes and immune subtypes.Conclusions:These findings indicated the significant role of m^(6)A-related lncRNAs in HCC and the potential application of the novel risk score model for prognostic prediction.Tianxing Dai Jing Li Linsen Ye Haoyuan Yu Mingbin Deng Wei Liu Hua Li Yang Yang Guoying Wang 2022Journal of Clinical and Translational Hepatology2022,10,2:1
19Mechanism of stepwise tectonic control on gas occurrence: A study in North China显示文摘To gain an understanding of gas occurrence, distribution is the fundamental basis for preventing gas disasters. Presently, how tectonic structures control gas occurrence remains problematic. This study proposes the theory and elucidates the mechanism of stepwise tectonic control on gas occurrence according to the characteristics of gas occurrence and the patterns of gas distribution in coal mines in North China. On the one hand, tectonic compression and shearing lead to stress concentration and thus deform the coal and reduce the coal seam permeability, further contributing to gas preservation. On the other hand, tectonic extension and rifting lead to stress release and thus improve the coal seam permeability, further contributing to gas emission. Therefore, the distribution zones of tectonic compression, ubiquitous coal deformation, and gas accumulation have been step-wisely revealed, and the coal-gas outburst proneness zones are finally identified. The proposed theory of step-wise tectonic control on gas occurrence is of practical significance for gas prediction and control.Jia Tianrang Zhang Zimin Wei Guoying Tang Chun'an 2015International Journal of Mining Science and Technology2015,25,4:1
