1Advanced Space-based Solar Observatory(ASO-S):an overview显示文摘The Advanced Space-based Solar Observatory(ASO-S)is a mission proposed for the 25 th solar maximum by the Chinese solar community.The scientific objectives are to study the relationships between the solar magnetic field,solar flares and coronal mass ejections(CMEs).Three payloads are deployed:the Full-disk vector Magneto Graph(FMG),the Lyman-αSolar Telescope(LST)and the Hard X-ray Imager(HXI).ASO-S will perform the first simultaneous observations of the photospheric vector magnetic field,non-thermal imaging of solar flares,and the initiation and early propagation of CMEs on a single platform.ASO-S is scheduled to be launched into a 720 km Sun-synchronous orbit in 2022.This paper presents an overview of the mission till the end of Phase-B and the beginning of Phase-C.Wei-Qun Gan Cheng Zhu Yuan-Yong Deng Hui Li Yang Su Hai-Ying Zhang Bo Chen Zhe Zhang Jian Wu Lei Deng Yu Huang Jian-Feng Yang Ji-Jun Cui Jin Chang Chi Wang Ji Wu Zeng-Shan Yin Wen Chen Cheng Fang Yi-Hua Yan Jun Lin Wei-Ming Xiong Bin Chen Hai-Chao Bao Cai-Xia Cao Yan-Ping Bai Tao Wang Bing-Long Chen Xin-Yu Li Ye Zhang Li Feng Jiang-Tao Su Ying Li Wei Chen You-Ping Li Ying-Na Su Hai-Yan Wu Mei Gu Lei Huang Xue-Jun Tang 2019Research in Astronomy and Astrophysics2019,19,11:17
2Hard X-ray Imager (HXI) onboard the ASO-S mission显示文摘Hard X-ray Imager(HXI)is one of the three scientific instruments onboard the Advanced Spacebased Solar Observatory(ASO-S)mission,which is proposed for the 25th solar maximum by the Chinese solar community.HXI is designed to investigate the non-thermal high-energy electrons accelerated in solar flares by providing images of solar flaring regions in the energy range from 30 keV to 200 keV.The imaging principle of HXI is based on spatially modulated Fourier synthesis and utilizes about 91 sets of bi-grid sub-collimators and corresponding LaBr3 detectors to obtain Fourier components with a spatial resolution of about 3 arcsec and a time resolution better than 0.5 s.An engineering prototype has been developed and tested to verify the feasibility of design.In this paper,we present background,instrument design and the development and test status of the prototype.Zhe Zhang Deng-Yi Chen Jian Wu Jin Chang Yi-Ming Hu Yang Su Yan Zhang Jian-Ping Wang Yao-Ming Liang Tao Ma Jian-Hua Guo Ming-Sheng Cai Yong-Qiang Zhang Yong-Yi Huang Xiao-Yan Peng Zong-Bin Tang Xuan Zhao Hong-He Zhou Lian-Guo Wang Jing-Xing Song Miao Ma Guang-Zhou Xu Jian-Feng Yang Di Lu Ying-Hong He Jin-You Tao Xiao-Long Ma Bao-Gang Lv Yan-Ping Bai Cai-Xia Cao Yu Huang Wei-Qun Gan 2019Research in Astronomy and Astrophysics2019,19,11:9

7Data reduction and calibration of the FMG onboard ASO-S显示文摘The Full-disk vector Magneto Graph(FMG)instrument will carry out polarization observations at one wavelength position of the Fe I 5324.179?spectral line.This paper describes how to choose this single wavelength position,the relevant data-processing and the magnetic field calibrations based on the measured polarization signals at one single wavelength position.It is found that solar radial Doppler velocity,which can cause the spectral line to shift,is a disadvantageous factor for the linear calibration at one wavelength position.Observations at two symmetric wavelength positions may significantly reduce the wavelength shift effect(~75%),but simulations show that such polarization signals located at the solar limbs(e.g.,beyond the longitude range of±30°)are not free from the effect completely.In future work,we plan to apply machine learning techniques to calibrate vector magnetic fields,or employ full Stokes parameter profile inversion techniques to obtain accurate vector magnetic fields,in order to complement the linear calibration at the single wavelength position.Jiang-Tao Su Xian-Yong Bai Jie Chen Jing-Jing Guo Suo Liu Xiao-Fan Wang Hai-Qing Xu Xiao Yang Yong-Liang Song Yuan-Yong Deng Kai-Fan Ji Lei Deng Yu Huang Hui Li Wei-Qun Gan 2019Research in Astronomy and Astrophysics2019,19,11:6

9The FAST Galactic Plane Pulsar Snapshot survey:I.Project design and pulsar discoveries显示文摘Discovery of pulsars is one of the main goals for large radio telescopes.The Five-hundredmeter Aperture Spherical radio Telescope(FAST),that incorporates an L-band 19-beam receiver with a system temperature of about 20 K,is the most sensitive radio telescope utilized for discovering pulsars.We designed the snapshot observation mode for a FAST key science project,the Galactic Plane Pulsar Snapshot(GPPS)survey,in which every four nearby pointings can observe a cover of a sky patch of 0.1575 square degrees through beam-switching of the L-band 19-beam receiver.The integration time for each pointing is 300 seconds so that the GPPS observations for a cover can be made in 21 minutes.The goal of the GPPS survey is to discover pulsars within the Galactic latitude of±10∘from the Galactic plane,and the highest priority is given to the inner Galaxy within±5∘.Up to now,the GPPS survey has discovered 201 pulsars,including currently the faintest pulsars which cannot be detected by other telescopes,pulsars with extremely high dispersion measures(DMs)which challenge the currently widely used models for the Galactic electron density distribution,pulsars coincident with supernova remnants,40 millisecond pulsars,16 binary pulsars,some nulling and mode-changing pulsars and rotating radio transients(RRATs).The follow-up observations for confirmation of new pulsars have polarization-signals recorded for polarization profiles of the pulsars.Re-detection of previously known pulsars in the survey data also leads to significant improvements in parameters for 64 pulsars.The GPPS survey discoveries are published and will be updated at http://zmtt.bao.ac.cn/GPPS/.J.L.Han Chen Wang P.F.Wang Tao Wang D.J.Zhou Jing-Hai Sun Yi Yan Wei-Qi Su Wei-Cong Jing Xue Chen X.Y.Gao Li-Gang Hou Jun Xu K.J.Lee Na Wang Peng Jiang Ren-Xin Xu Jun Yan Heng-Qian Gan Xin Guan Wen-Jun Huang Jin-Chen Jiang Hui Li Yun-Peng Men Chun Sun Bo-Jun Wang H.G.Wang Shuang-Qiang Wang Jin-Tao Xie Heng Xu Rui Yao Xiao-Peng You D.J.Yu Jian-Ping Yuan Rai Yuen Chun-Feng Zhang Yan Zhu 2021Research in Astronomy and Astrophysics2021,21,5:4

12The Science Operations and Data Center (SODC) of the ASO-S mission显示文摘A ground data analysis center is very important to the success of a mission.We introduce the Science Operations and Data Center(SODC)for the ASO-S mission,which consists of a scientific operation subcenter,a data management subcenter,a data analysis subcenter and a user service subcenter.The mission planning process,instrument observation modes and the data volume are presented.We describe the data flow and processing procedures from spacecraft telemetry to high-level science data,and the long-term archival as well.The data policy and distributions are also briefly introduced.Yu Huang Hui Li Wei-Qun Gan You-Ping Li Jiang-Tao Su Yuan-Yong Deng Li Feng Yang Su Wei Chen Shi-Jun Lei Ying Li Yun-Yi Ge Ying-Na Su Si-Ming Liu Jing-Jing Zang Zun-Lei Xu Xian-Yong Bai Jing-Wei Li 2019Research in Astronomy and Astrophysics2019,19,11:3
13Joint hard X-ray observations with ASO-S/HXI and SO/STIX显示文摘This paper discusses the potential of future joint hard X-ray solar flare observations between the Hard X-ray Imager(HXI)onboard the Advanced Space-based Solar Observatory(ASO-S)mission and the Spectrometer/Telescope for Imaging X-rays(STIX)on Solar Orbiter.The different viewing perspectives of the two telescopes relative to the Sun will allow us for the first time to systematically study non-thermal hard X-ray emissions stereoscopically.During the 4-years of the nominal mission of ASO-S,we expect to jointly observe about 160 flares above GOES M1 class to systematically study hard X-ray directivity.For about 16 partially limb-occulted STIX flares,we will have observations of the entire flare by HXI.Such observations will enable us to simultaneously study the all-important coronal hard X-ray sources,which are generally lost in the instrument’s individual imaging dynamic range,in combination with the chromospheric footpoint emissions.The two different detector systems used in the two telescopes make the relative calibration between the two instruments a key task that needs to be addressed before creditable science results can be published.If an accurate inter-calibration can be achieved using jointly observed flares on the disk,observations with HXI and STIX will provide new and essential key diagnostics for solar flare physics.Sam Krucker Gordon JHurford Yang Su Wei-Qun Gan 2019Research in Astronomy and Astrophysics2019,19,11:3
14Carbon combustion synthesis of lithium cobalt oxide as cathode material for lithium ion battery显示文摘Lithium cobalt oxide(LiCoO2) was synthesized by carbon combustion synthesis(CCS) using carbon as fuel.X-ray diffraction(XRD) and scanning electron microscope(SEM) measurements showed that carbon combustion led to the formation of layered structure of LiCoO2 and the particle size could be controlled by carbon content.For the LiCoO2 sample prepared at 800℃ for 2 h,at molar ratio of C/Co=0.5,the particle-size distribution fell in the narrow range of 3-5 m.Electrochemical tests indicated this LiCoO2 sample delivered an initial discharge capacity of 148 mAh/g with capacity retention rate higher than 97% after 10 cycles.Yongle Gan Li Zhang Yanxuan Wen Fan Wang Haifeng Su 2008Particuology2008,6,2:3
15Parametrization of woods-saxon potential for heavy-ion systems显示文摘Several elastic scattering angular distributions of ^(12)C from target nuclei of A ≥39 are analyzed to extract the Woods-Saxon potential parameters with the fixed imaginary potential and Coulomb radius parameters.Using the best fitted diffuseness parameters,the correlations of the real part parameters with A_1^(1/3)+ A_2^(1/3) and incident energy are revealed, and the systematic Woods-Saxon potential parameters are presented for nucleus-nucleus interaction.The proposed potential parameters can reproduce not only the elastic scattering angular distributions induced by ^(12)C,but also many elastic scattering angular distributions induced by the projectiles other than ^(12)C,thus providing important inputs for the study of nuclear reactions of heavy-ion systems.Lin Gan ZhiHong Li HuiBin Sun DanYang Pang Bing Guo YunJu Li Jun Su ShengQuan Yan ErTao Li YouBao Wang Gang Lian ZhiYu Han XinYue Li DongHui Li TianLi Ma ChangJin Pei YangPing Shen Yi Su Sheng Zeng Yong Zhou WeiPing Liu 2017Science China(Physics,Mechanics & Astronomy)2017,60,8:2
16Double hard X-ray peaks in RHESSI flares as evidence of chromospheric evaporation and implications for modifying the Neupert effect显示文摘Among the RHESSI flare samples,we concentrated on a kind of flare that presents two successive peaks(that is,it presents both an impulsive phase and a gradual phase)in 12-25 keV light curves.Taking the C1.4 flare on 2002 August 12 as an example,we studied the light curves,spectra,and images in detail.Making full use of the capabilities of RHESSI,we showed some evidence to support the expected causal relationship between these two peaks:the first peak is mainly nonthermal,while the second peak is mainly thermal;the energy carried by nonthermal electrons during the first peak seems to be comparable to the thermal energy of the second peak.The morphologies of X-ray images and their evolutions provide additional evidence for this causality.We conclude that two such peaks in the 12-25 keV light curve are good evidence for the chromospheric evaporation.However,the maximum time of the second peak is later than the end time of the first peak,suggesting that for some events,a modification of the traditional Neupert effect could be necessary by inclusion of a time delay,which might be partly related to the filling of the loop by evaporated material.You-Ping Li Wei-Qun Gan Yang Su 2009Research in Astronomy and Astrophysics2009,9,10:2
17EjBZR1 represses fruit enlargement by binding to the EjCYP90 promoter in loquat显示文摘Loquat(Eriobotrya japonica)is a subtropical tree that bears fruit that ripens during late spring.Fruit size is one of the dominant factors inhibiting the large-scale production of this fruit crop.To date,little is known about fruit size regulation.In this study,we first discovered that cell size is more important to fruit size than cell number in loquat and that the expression of the EjBZR1 gene is negatively correlated with cell and fruit size.Virus-induced gene silencing(VIGS)of EjBZR1 led to larger cells and fruits in loquat,while its overexpression reduced cell and plant size in Arabidopsis.Moreover,both the suppression and overexpression of EjBZR1 inhibited the expression of brassinosteroid(BR)biosynthesis genes,especially that of EjCYP90A.Further experiments indicated that EjCYP90A,a cytochrome P450 gene,is a fruit growth activator,while EjBZR1 binds to the BRRE(CGTGTG)motif of the EjCYP90A promoter to repress its expression and fruit cell enlargement.Overall,our results demonstrate a possible pathway by which EjBZR1 directly targets EjCYP90A and thereby affects BR biosynthesis,which influences cell expansion and,consequently,fruit size.These findings help to elucidate the molecular functions of BZR1 in fruit growth and thus highlight a useful genetic improvement that can lead to increased crop yields by repressing gene expression.Wenbing Su Zikun Shao Man Wang Xiaoqing Gan Xianghui Yang Shunquan Lin 2021Horticulture Research2021,8,1:2
18Volatile Oil of Platycladus Orientalis(L.)Franco Leaves Exerts Strong Anti-inflammatory Effects via Inhibiting the IκB/NF-κB Pathway显示文摘This study was designed to investigate the anti-inflammatory effects of volatile oil of Platycladus orientalis(L.)Franco leaves(VOPF)and the underlying molecular mechanisms by using the non-infectious inflammation rat models and infectious inflammation mouse models.Ear swelling and intraperitoneal capillary permeability in mice,and carrageenan-induced toe swelling and cotton ball-induced granuloma in rats were used to reveal anti-inflammatory effects of VOPF.Moreover,the lipopolysaccharide(LPS)-induced mouse model of acute lung injury was used to explore the anti-inflammatory mechanism of VOPF.The results showed that VOPF could significantly inhibit auricular swelling,intraperitoneal capillary permeability in mice,and reduce granuloma swelling and paw swelling in rats.Furthermore,it significantly alleviated the pathological damage of the lung tissue.In addition,VOPF could reduce the contents of IL-1β and TNF-αand increase the content of IL-10 in the serum.It had little effect on the expression of p65 but reduced the phosphorylation level of p65 and IκB in NF-κB pathway.In conclusion,VOPF has anti-inflammatory effects and the mechanisms involve the down-regulation of the phosphorylation levels of p65 and IκB and blockage of the NF-κB signaling pathway.Da-li GAN Yan YAO Han-wen SU Yu-ying HUANG Jun-feng SHI Xiong-biao LIU Mei-xian XIANG 2021Current Medical Science2021,41,1:2
