| 1 | Fast acceleration of “killer” electrons and energetic ions by interplanetary shock stimulated ULF waves in the inner magnetosphere显示文摘Energetic electrons and ions in the Van Allen radiation belt are the number one space weather threat. Understanding how these energetic particles are accelerated within the Van Allen radiation belt is one of the major challenges in space physics. This paper reviews the recent progress on the fast acceleration of 'killer' electrons and energetic ions by ultralow frequency (ULF) waves stimulated by the interplanetary shock in the inner magnetosphere. Very low frequency (VLF) wave-particle interaction is considered to be one of the primary electron acceleration mechanisms because electron cyclotron resonances can easily occur in the VLF frequency range. Recently, using four Cluster spacecraft observations, we have found that, after interplanetary shocks impact the Earth’s magnetosphere, energetic electrons in the radiation belt are accelerated almost immediately and continue to accelerate for a few hours. The time scale (a few days) for traditional acceleration mechanisms, based on VLF wave-particle interactions to accelerate electrons to relativistic energies, is too long to explain our observations. Furthermore, we have found that interplanetary shocks or solar wind pressure pulses, with even small dynamic pressure changes, can play a non-negligible role in radiation belt dynamics. Interplanetary shocks interaction with the Earth’s magnetosphere manifests many fundamental space physics phenomena including energetic particle acceleration. The mechanism of fast acceleration of energetic electrons in the radiation belt responding to interplanetary shock impacts consists of three contributing parts: (1) the initial adiabatic acceleration due to strong shock-related magnetic field compression; (2) followed by the drift-resonant acceleration with poloidal ULF waves excited at different L-shells; and (3) particle acceleration due to the quickly damping electric fields associated with ULF waves. Particles end up with a net acceleration because they gain more energy in the first half of this cycle than they lose in the second. The results reported in this paper cast a new light on understanding the acceleration of energetic particles in the Earth’s Van Allen radiation belt. The results of this study can likewise be applied to interplanetary shock interaction with other planets such as Mercury, Jupiter, Saturn, Uranus and Neptune, and other astrophysical objects with magnetic fields. | ZONG QiuGang WANG YongFu YUAN ChongJing YANG Biao WANG ChenRui ZHANG XiangYun | 2011 | Chinese Science Bulletin2011，56，12： | 11 |

| 3 | Applications of Electrical Capacitance Tomography in Two Phase Flow Visualization显示文摘The successful application of Electrical Capacitance Tomography (ECT) depends heavily on the image reconstruction speed and quality. The two requirements usually cannot be satisfied simultaneously. Also, for a large number of acquired 2D ECT images, a 3D presentation of them is much desired to track the variations of the material distribution in a third dimension. To facilitate ECT for practical flow analyses in process engineering, the authors have recently developed algorithms for 3D image presentation and for online iterative image reconstruction that only takes the same time as a linear back projection method but yields good image qualities as the Landweber iterative method does. The new methods have been successfully applied to visualize several classes of two phase flows, namely fluidization, cyclone separation, circulating rate determination in circulating fluidized beds, pneumatic conveying, rotating drum mixing. Special characteristics in each case have been discussed and valuable results are obtained, which are reported in this paper. | Shi Liu Runsheng Yan Haigang Wang Fan Jiang Xiangyun Dong | 2004 | Journal of Thermal Science2004，13，2： | 9 |
| 4 | Numerical simulation of magnetospheric ULF waves excited by positive and negative impulses of solar wind dynamic pressure显示文摘The sources of ultra low frequency (ULF) waves in the magnetosphere are generally believed to be either the external solar wind perturbations or the internal plasma instabilities. When a sudden impulse of the solar wind dynamic pressure impinges on the magnetopause, ULF waves might be excited and thus the solar wind energy is transported into the earth's magnetosphere. In this paper, we study the ULF waves excited by different kinds of sudden solar wind pressure impulses through an MHD simulation. We primarily focus on the responses of the earth's magnetosphere to positive/negative impulses of solar wind dynamic pressure, and positive-negative impulse pairs. The simulation results show that the ULF waves excited by positive and negative impulse have the same amplitude and frequency, with 180° difference in phase, if the amplitude and durations of the input impulses are the same. In addition, it is found that field line resonances (FLRs) occur at certain L-shell regions of the earth's magneto-sphere after the impact of different positive-negative impulse pairs, which appear to be related to the duration of the impulses and the time interval between the sequential impulses. Another result is that the energy from the solar wind could be transported deeper into the inner magnetosphere by an impulse pair than by a single pulse impact. The results presented in this paper could help us to better understand how energy is transported from solar wind to the earth's magnetosphere via ULF waves. Also, these results provide some new clues to understanding of how energetic particles in the inner magnetosphere response to different kinds of solar wind pressure impulse impacts including inter-planetary shocks. | ZHANG XiangYun ZONG QiuGang YANG Biao WANG YongFu | 2009 | Science China(Technological Sciences)2009，52，10： | 6 |

| 6 | Chemical speciation code CHEMSPEC and its applications显示文摘The adsorption and migration behavior of a radionuclide in geological media heavily depends on its chemical forms in a given chemical environment.In order to predict the temporal and spatial distribution of radionuclides around a disposal site when its canister is damaged,it is necessary to develop coupled chemical speciation-solute transport models and relevant software.For that reason,we wrote a new chemical speciation program CHEMSPEC.In this paper,the principles and structure of CHEMSPEC are briefly described,and the strategy and algorithms that were used in this code are interpreted in some detail,such as the measures adopted to prevent divergence in iteratively solving the mass balance equations,the 'predictor-corrector' algorithm for calculation of the number and quantities of solid species formed,and the alternate use of 'freezing' and 'defreezing' oxidation states in handling of co-existent redox and precipitation equilibria.Four examples are given to illustrate CHEMSPEC's features and capabilities. | WANG XiangYun CHEN Tao LIU ChunLi | 2009 | Science China Chemistry2009，52，11： | 5 |

| 8 | Rational development of a human antibody cocktail that deploys multiple functions to confer Pan-SARS-CoVs protection显示文摘Structural principles underlying the composition and synergistic mechanisms of protective monoclonal antibody cocktails are poorly defined.Here,we exploited antibody cooperativity to develop a therapeutic antibody cocktail against SARS-CoV-2.On the basis of our previously identified humanized cross-neutralizing antibody H014,we systematically an a lyzed a fully human n aive antibody library and rationally identified a potent neutralizing antibody partner,P17,which confers effective protection in animal model.Cryo-EM studies dissected the nature of the P17 epitope,which is SARS-CoV-2 specific and distinctly different from that of HOI4.High-resolution structure of the SARS-CoV-2 spike in complex with HOM and P17,together with functional investigations revealed that in a two-antibody cocktail,synergistic neutralization was achieved by S1 shielding and conformational locking,thereby blocking receptor attachment and viral membrane fusion,conferring high potency as well as robustness against viral mutation escape.Furthermore,cluster analysis identified a hypothetical 3rd antibody partner for further reinforcing the cocktail as pan-SARS-CoVs therapeutics. | Hangping Yao Yao Sun Yong-Qiang Deng Nan Wang Yongcong Tan Na-Na Zhang Xiao-Feng Li Chao Kong Yan-Peng Xuc Qi Chen Tian-Shu Cao Hui Zhao Xintian Yan Lei Cao Zhe Lv Dandan Zhu Rui Feng Nanping Wu Wenhai Zhang Yuhao Hu Keda Chen Rong-Rong Zhang Qingyu Lv Shihui Sun Yunhua Zhou Run Yan Guan Yang Xinglu Chanjuan Liu Xiangyun Lu Linfang Cheng Hongying Qiu Xing-Yao Huang Tianhao Weng Danrong Shi Weidong Jiang Junbin Shao Lei Wang Jie Zhang Tao Jiang Guojun Lang Cheng-Feng Qinc Lanjuan Li Xiangxi Wang | 2021 | Cell Research2021，31，1： | 5 |
| 9 | Phyto-phospholipid complexes(phytosomes): A novel strategy to improve the bioavailability of active constituents显示文摘Although active constituents extracted from plants show robust in vitro pharmacological effects, low in vivo absorption greatly limits the widespread application of these compounds. A strategy of using phyto-phospholipid complexes represents a promising approach to increase the oral bioavailability of active constituents, which is consist of ‘‘label-friendly'phospholipids and active constituents. Hydrogen bond interactions between active constituents and phospholipids enable phospholipid complexes as an integral part. This review provides an update on four important issues related to phyto-phospholipid complexes: active constituents, phospholipids, solvents, and stoichiometric ratios. We also discuss recent progress in research on the preparation, characterization, structural verification, and increased bioavailability of phyto-phospholipid complexes. | Mei Lu Qiujun Qiu Xiang Luo Xinrong Liu Jing Sun Cunyang Wang Xiangyun Lin Yihui Deng Yanzhi Song | 2019 | Asian Journal of Pharmaceutical Sciences2019，14，3： | 4 |
| 10 | The Deep Geophysical Structure of the Middle Section of the Longmen Mountains Tectonic Belt and its Relation to the Wenchuan Earthquake显示文摘Investigation of the deep geophysical structure of the Longmen Mountains tectonic belt and its relation to the Wenchuan Earthquake is important for the study of earthquakes. By using magnetotelluric sounding profiles of the Luqu–Zhongjiang and Anxian–Suining; seismic sounding profiles of the Sichuan Maowen–Chongqing Gongtan, the Qinghai Huashi Gorge–Sichuan Jianyang, and the Batang–Zizhong; and magnetogravimetric data of the Longmen Mountains region, the deep geophysical structure of the Songpan–Ganzi block, the western Sichuan foreland basin, and the Longmen Mountains tectonic belt and their relation was discussed. The eastward extrusion of the Qinghai–Tibet Plateau thrusts the Songpan–Ganzi block upon the Yangtze block, which obstructs the eastward movement of the Qinghai–Tibet Plateau. The Maoxian–Wenchuan, Beichuan–Yingxiu, and Anxian–Guanxian faults of the Longmen Mountains fault belt dip to northwest with different dip angles and gradually converge in the deeper parts. Geophysical structure suggests that an intracrustal low-velocity, low-resistivity, and high-conductivity layer is common between the middle and upper crust west of the Longmen Mountains tectonic belt but not in the upper Yangtze block. The Sichuan Basin has a thick low-resistance sedimentary layer on a stable high-resistance basement; moreover, there are secondary paleohighs and depression structures at the lower part of the western Sichuan foreland basin with characteristic of high magnetic anomalies, whereas the Songpan–Ganzi block has a high resisitivity cover of upper crust and continues to a low-resistance layer. Considering the Longmen Mountains tectonic belt as the boundary, there are Bouguer gravity anomalies of 'one belt between two zones.' Thus, we infer that there is a corresponding relation between the inferred crystalline basement of the Songpan block and the underlying basin basement of the Longmen Mountains fault belt. Furthermore, there may be an extensive ancient Yangtze block, which is west of the Ruoergai block. In addition, the crust–mantle ductile shear zone under the Longmen Mountains tectonic belt is the main fault, whereas the Beichuan–Yingxiu and Anxian–Guanxian faults at the surface are earthquake faults. The Wenchuan Ms 8.0 earthquake might be attributed to the collision of the Yangtze block and the Qinghai–Tibet Plateau. The eastward obduction of the eastern edge of the Qinghai–Tibet Plateau and eastward subduction of its deeper part under the influence of the collision of the Indian, Pacific, and Philippine Plates with the Eurasia Plate might have caused the Longmen Mountains tectonic belt to cut the Moho and extend to the middle and upper crust; thus, creating high stress concentration and rapid energy release zone. | YU Nian WANG Xuben HU Xiangyun CAI Xuelin KAN Aike ZHAO Ning | 2014 | Acta Geologica Sinica(English Edition)2014，88，2： | 4 |

| 12 | The effects of modulation period,modulation ratio,and deposition temperature on microstructure and mechanical properties of ZrB_2/W multilayers显示文摘Monolithic ZrB2,W coatings and ZrB2/W multilayers with different modulation periods and modulation ratios were synthesized by ion beam assisted deposition at room temperature and 400°C.X-ray diffraction (XRD),scanning electron microscopy (SEM),surface profiler,and nanoindention were employed to investigate the influences of the deposition temperature and the modulation period on the growth,textures,interface structure,and mechanical properties of the multilayers.The results indicated that the multilayer with modulation period of 13 nm synthesized at room temperature possessed a higher hardness of 23.8 GPa.Deposition temperature gave a significant contribution to mechanical property enhancement.The 400°C-deposition temperature led to a maximum hardness and elastic modulus value of 32.1 and 399.1 GPa for ZrB2/W multilayer with a modulation period of 6.7 nm.Its critical load increased to 42.8 mN and residual stress decreased to -0.7 GPa.A higher deposition temperature can cause an increase in interfacial atomic mixture and mobility of surface species,which induceds an increase in areal atomic density and dislocation pinning.These results as well as small nanoscale grain sizes should be related to hardness increase. | LIU MengYin,TAN Ming,LIU GuangQing,WANG HaiYuan,XUE FengYing,DENG XiangYun & LI DeJun College of Physics and Electronic Information Science,Tianjin Normal University,Tianjin 300387,China | 2010 | Science China(Technological Sciences)2010，53，9： | 4 |
| 13 | ESCRT-I Component VPS23A Is Targeted by E3 Ubiquitin Ligase XBAT35 for Proteasome-Mediated Degradation in Modulating ABA Signaling显示文摘A myriad of abiotic stress responses in plants are controlled by abscisic acid(ABA)signaling.ABA receptors can be degraded by both the 26S proteasome pathway and vacuolar degradation pathway after processing via the endosomal sorting complex required for transport(ESCRT)proteins.Despite being essential for ABA signaling,the upstream regulators of ESCRTs remain unknown.Here,we report that the ESCRT-I component VPS23A is an unstable protein that is degraded via the ubiquitin-proteasome system(UPS).The UEV domain of VPS23A physically interacts with the two PSAP motifs of XBAT35,an E3 ubiquitin ligase,and this interaction results in the deposition of K48 polyubiquitin chains on VPS23A,marking it for degradation by 26S proteasomes.We showed that XBAT35 in plants is a positive regulator of ABA responses that acts via the VPS23A/PYL4 complex,specifically by accelerating VPS23A turnover and thereby increasing accumulation of the ABA receptor PYL4.This work deciphers how an ESCRT component is regulated in plants and deepens our understanding of plant stress responses by illustrating a mechanism whereby crosstalk between the UPS and endosome-vacuole-mediated degradation pathways controls ABA signaling. | Feifei Yu Xiaoqiang Cao Guangchao Liu Qian Wang Ran Xia Xiangyun Zhang Qi Xie | 2020 | Molecular Plant2020，13，11： | 4 |
| 14 | Refinement of the crystal structure for a new mineral──antimonselite显示文摘The crystal structure of a new mineral of the stibnite group, Sb-2Se-3, has been determined. The cell constants, obtained by least-squares calculation from direct θ -value’s measurements on the diffractometer are: a =1.158 8(5), b =1.174 4(4), c =0.395 5(2) nm; orthorhombic; V =0.538 23 nm+3; Z =4. The space group is Pbnm. X-ray single crystal data, using Mo K α radiation, were measured on a RIGAKU RASA-5RP automated diffractometer and refined to a final R index of 0.048 1. Sb-2Se-3 is isostructural with Sb-2S-3 and Bi-2S-3. Each Sb(1) atom is six-coordinated by 3 Se(1), 1 Se(2) and 2 Se(3) atoms at distances 0.266 0-0.323 6 nm. Each Sb(2) atom is seven-coordinated by 2 Se(1), 2 Se(2) and 3 Se(3) atoms at distances of 0.258 1- 0.346 7 nm. The crystal structure consists of chains parallel to c or needle axis. The strongest bonds (shortest separations) are within the chains. Many important physical properties of antimonselite (optical, ferroelectric, etc.) are related to its crystal structure. | MIN Maozhong 1, ZHAI Jianping 1, WANG Xiangyun 1,SHEN Baopei 2, WEN Guangdou 2 and FAN Tao 21.

| 15 | Chinese Teachers’Professional Identity and Beliefs about the Teacher-Student Relationships in an Intercultural Context显示文摘This paper presents a qualitative study of immigrant Chinese teachers’professional identity and beliefs about the teacher-student relationship in an intercultural context.Theoretically,this study takes its departure from a sociocultural perspective on understanding professional identity.The empirical analysis in the study drew mainly upon ethnographic interviews with a group of Chinese language teachers in Denmark concerning their life experiences,perceptions,and beliefs.The results of this study suggest that teachers’beliefs about their roles as teachers and about student-teacher relationships are shaped by both their prior experiences and backgrounds and the current social and cultural contexts in which they are situated.Changes of context(e.g.,from China to Denmark)often lead to a transformation of their professional identity and beliefs.Being a teacher in an intercultural context often exposes them to the confrontation of diverse challenges and dilemmas.On one hand,teachers in this study generally experienced a transformation from being a moral role model,subject expert,authority and parental role to being a learning facilitator and culture worker.On the other hand,they developed diverse individualized coping strategies to handle student-teacher interactions and other aspects of teachers’professional identity. | Li WANG Xiangyun DU | 2014 | Frontiers of Education in China2014，9，3： | 2 |
| 16 | Human health ambient water quality criteria for 13 heavy metals and health risk assessment in Taihu Lake显示文摘Heavy metals are widely concerning because of their toxicity,persistence,non-degradation and bioaccumulation ability.Iluman health ambient water quality criteria(AWQC)are specific levels of chemicals that can occur in water without harming human health.At present,most countries do not consider the effects of aquatic vegetables in deriving human health AWQC.Therefore,the intake of aquatic vegetables(Brasenia schreberi)was added to the derivation of human health AWQC and a health risk assessment for 13 heavy metals in Taihu Lake.The human health AWQC(consumption of water,fish and aquatic vegetables)values of 13 heavy metals ranged from 0.04(Cd)to 710.87μg/L(Sn),and the intake of B.schreberi had a very significant effect on the human health AWQC for Cu,with a more than 62-fold difference.The hazard quotients of As(2.8),Cd(1.6),Cr(1.4)and Cu(4.86)were higher than the safe level(HQ=1),indicating that As,Cd,Cr and Cu in Taihu Lake posed a significant health risk.Sensitivity analysis showed that the contribution rate of B.schreberi intake to the human health risk from Cu was 91.6%,and all results indicated that the risk of Cu in B.schreberi to human health should be of particular concern.This study adds the consideration of aquatic vegetable consumption to the traditional method of human health AWQC derivation and risk assessments for the first time,and this approach can promote the development of risk assessments and water quality criteria. | Liang Cui Ji Li Xiangyun Gao Biao Tian Jiawen Zhang Xiaonan Wang Zhengtao Liu | 2022 | Frontiers of Environmental Science & Engineering2022，16，4： | 2 |
| 17 | Research of an SHPB Device in Two-by-Two Form for Impact Experiments of Concrete-Like Heterogeneous Materials显示文摘A split Hopkinson pressure bar(SHPB)device in two-by-two form,including the bar bundle form and the single cylindrical bar form,was designed in response to the demand for the dynamic mechanical experiments for brittle materials such as concrete,rock,etc.The stress waveforms generated through a projectile impacting two different types of incident bars have been studied based on the one-dimensional stress wave theory and numerical simulation method.At last,based on the established two types of mesoscale concrete models with random convex polyhedral aggregates,we performed comparison analysis of SHPB numerical simulations for concrete materials with bar bundle and single cylindrical bar separately,so as to provide technical support for the manufacture and development of this experimental device.The results showed that the introduced two-by-two form SHPB device expanded the scope of practical application,and the wave dispersion effect existing in a large-diameter bar can be evidently reduced when we employed the bar bundle form,indicating its applicability to the dynamic mechanical experiments of concrete-like heterogeneous materials. | Ruiqi Guo Huiqi Ren Lei Zhang Zhilin Long Xiangyun Wu Hailu Wang | 2021 | Acta Mechanica Solida Sinica2021，34，4： | 2 |
| 18 | Application of ERS-1 scatterometer data to studying land surfaces ──Distributive characteristic of backscattering coefficient over China land surfaces显示文摘ERS 1 WSC data were obtained by international cooperation. The distributive characteristics of radar backscattering coefficient image of China land surface are analyzed and the research results are presented. The capability of ERS 1 WSC data for monitoring land surfaces is investigated. The results show that the radar backscattering coefficient images can reveal the natural landform features of China land. Using the WSC data can discriminate six types of major land coverage, including evergreen vegetation and snow covered region, vegetation and crops, mountains, grassland, desert and grassland, desert. On the whole, the radar backscattering coefficient image of China land is the synthesis of the vegetation map and terrain map. Statistical study of the typical terrain shows that the radar backscatter coefficients of China land range from -29 dB to -5 dB. The lowest value corresponds to the deserts of Badain Jaran, Takla Makan, and Tengger. The highest value corresponds to snow covered regions of Himalaya Mountains and Tianshan Mountains. | WANG Xiangyun 1, WANG Chao 2, GUO Huadong 2 and SHI Yangshen 1 1.
