| 1 | Geochemistry, geochronology, and petro-genesis of the early Paleozoic granitic plutons in the central-southern Jiangxi Province,China显示文摘This paper reports the systematic study on petrology, geochemistry, LA ICPMS zircons U-Pb dating, and in situ Hf isotope geology of the four plutons in the central-southern Jiangxi Province, an important part of the South China Block. In the outcrops, rocks are gradually changed from wall rock (slate or schist) to pluton (gneissic granite); some residual blocks of sandy rock occur in the margin of pluton, and the foliations of residual blocks are parallel to those of both wall rock and gneissic granite. The thin-section observations show that the four plutons contain peraluminous minerals such as muscovite and sillimanite. The flattened and elongated feldspar and quartz grains are often visible in the gneissic granite, parallel to direction of lineation, suggesting that the granitic rock were subjected to a strong ductile shearing. Geochemically, the A/CNK values from 13 granitic samples are between 1.03 and 1.37 with an average of 1.16, indicating that the granites are of strongly peraluminous plutons. The REE compositions of the 13 samples are similar, showing higher REE contents, with enrichment in LREEs, depletion in Eu and REE patterns with relative LREE-enrichment and negligible Eu anomalies. They show enrichment in Rb, Th, U and depletion in Ba, Sr, Nb, Ti, belonging to a low Ba-Sr type of granite. Thus, the four bodies should be derived from the same magmatic source. Zircons used as U-Pb dating mostly exhibit euhedral shape and high Th/U values from 0.52 to 1.54 with an average of 1.08, suggesting that most zircons are of magmatic genesis. The zircons from four plutons yielded rather similar 206 Pb/ 238 U vs. 207 Pb/ 235 U concordia ages: 436.1±5.7 Ma for the Tangwan granite, 440.6±4 Ma for the Jiekou gneissic granite, 435.9±6.2 Ma for the Dongbao gneissic granite, and 441.9±3.1 Ma for the Jinxi K-granite, respectively, corresponding to Silurian Llandovery. Several xenocrysts yielded U-Pb ages around 700 Ma, implying that a breakup event took place during Neoproterozoic in the South China Block. In situ Lu-Hf isotopic analysis shows that all Hf (t) values of zircons are negative and have two-stage Hf model ages (TDM2) from 1.4 to 3.6 Ga, indicating that the Silurian granitic magma came from the recycle of Meso-Paleoproterozoic basement and even partly Archean rocks, and had not been effected by mantle magma. Researches on regional geology suggest that an intracontinental tectono-magmatic event took place during the early Paleozoic in the study areas, which is characterized by folding and thrusting, leading to crustal shortening and thickening, up to 20 km thickness. The high geothermal temperature from thickening crust and accumulation of producing high-heat radioactive elements gradually softened crustal rocks and caused a partial melting, forming peraluminous granitic magma. Under the post-orogenic extensional and de-pressure condition, these granitic magma rose and was emplaced in the upper crust, leading to development of S-type | ZHANG Yuan SHU LiangShu CHEN XiangYun | 2011 | Science China Earth Sciences2011，54，10： | 23 |

| 3 | 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 |

| 5 | Temperature-dependent THz vibrational spectra of clenbuterol hydrochloride显示文摘Using the high-resolution Terahertz Time-domain spectroscopy (THz-TDS) and the standard sample pellet technique, the far-infrared vibrational spectra of clenbuterol hydrochloride (CH), a 2 -adrenergic agonist for decreasing fat deposition and enhancing protein accretion, were measured in temperature range of 77-295 K. Between 0.2 and 3.6 THz (6.6-120.0 cm-1 ), seven highly resolved spectral features, strong line-narrowing and a frequency blue-shift were observed with cooling. However, ractopamine hydrochloride, with some structural and pharmacological similarities to clenbuterol hydrochloride, showed no spectral features, indicating high sensitivity and strong specificity of THz-TDS. These results could be used for the rapid and nondestructive CH residual detection in food safety control. | YANG YuPing LEI XiangYun YUE Ai ZHANG ZhenWei | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，4： | 9 |
| 6 | Sedimentary Evolution and Transgressions of the Western Subei Basin in Eastern China since the Late Pliocene显示文摘Sedimentary sequences in the Subei Basin are complex and have been affected by interactions between the ocean and rivers since the Late Pliocene, including the Yellow River, Huaihe River, and the Yangtze River. This sedimentary evolution, in particular the timing of Pleistocene transgressions, has long been a matter of controversy owing to the lack of precise chronological evidence. The aim of this study is to explore the evolution of the sedimentary environment throughout the past 3.00 Ma in this region on the basis of a comprehensive analysis of particle size and foraminifera and ostracods collected in the TZK9 core from the Subei Basin combined with geochronological studies of magnetostratigraphy, AMS^(14)C and optically stimulated luminescence(OSL). The results show that fluvial facies in the sedimentary environment from 3.00 to 1.01 Ma. There were fluvial facies and reflects six sea-level high stands from 1.01 to 0.25 Ma. The study area was affected by four large-scale transgressions since 0.25 Ma. The four marine sedimentary layers known as DU7(buried at 48–52 m), DU5(buried at 35–41 m), DU3(buried at 16–23 m), and DU1(buried at 2–4 m) are recorded in the MIS7(210–250 ka), MIS5, MIS3, and Holocene, respectively. The magnitude of the DU5 transgression was identical to that of the DU3 transgression, both were larger than the DU7 transgression, and the DU1 transgression was the weakest. The variation of transgression strength reflects the influence of global changes in sea level, tectonic subsidence, shell ridges, and sand dams. In the TZK9 core, we found evidence of seven sea-level high stands from the Early–Middle Pleistocene, and the first one caused by regional rapid subsidence and could be traced back to 0.83-0.84 Ma. The sea-level high stands and the age of the first one recorded above was different from other cores in eastern China, this was caused by the lack of absolute age control and the differences in paleotopography during this period. This study reconstructs sedimentary evolution, determines the transgression and its age, establishes the chronology since the Late Pliocene, and provides a scientific framework for further paleoenvironmental and tectonic studies. The results of this study highlight the important role that local tectonics and global sea level play in the sedimentary evolution and transgressions that have occurred in the western Subei Basin. | CHENG Yu LI Xiangqian SHU Junwu BAI Shibiao ZHAO Zengyu ZHANG Xiangyun GUO Gang ZHANG Ping LIN Jingxing | 2019 | Acta Geologica Sinica(English Edition)2019，93，1： | 7 |
| 7 | Melatonin enhances radiofrequency-induced NK antitumor immunity,causing cancer metabolism reprogramming and inhibition of multiple pulmonary tumor development显示文摘Surgery is the comm on treatme nt for early lung cancer with multiple pulm onary no dules,but it is often accompanied by the problem of significant malignancy of other nodules in non-therapeutic areas.In this study,we found that a combined treatment of local rad iofreq ue ncy ablati on(RFA)and melatonin(MLT)greatly improved clinical outcomes for early lung cancer patie nts with multiple pulmonary nodules by minimizing lung function injury and reducing the probability of malignant transformation or enlargement of nodules in non-ablated areas.Mechanically,as demonstrated in an associated mouse lung tumor model,RFA not only effectively remove treated tumors but also stimulate antitumor immunity,which could inhibit tumor growth in non-ablated areas.MLT enhanced RFA-stimulated NK activity and exerted synergistic antitumor effects with RFA.Transcriptomics and proteomics analyses of residual tumor tissues revealed enhanced oxidative phosphorylation and reduced acidification as well as hypoxia in the tumor microenvironment,which suggests reprogrammed tumor metabolism after combined treatment with RFA and MLT.Analysis of residual tumor further revealed the depressed activity of MAPK,NF-kappa B,Wnt,and Hedgehog pathways and upregulated P53 pathway in tumors,which was in line with the inhibited tumor growth.Combined RFA and MLT treatment also reversed the Warburg effect and decreased tumor malignancy.These findings thus demonstrated that combined treatment of RFA and MLT effectively inhibited the malignancy of non-ablated nodules and provided an innovative non-invasive strategy for treating early lung tumors with multiple pulmonary nodules.Trial registration:www.chictr.org.cn,identifier ChiCTR2100042695,http://gffzz62a03ee25e6f4a77h6wwqnkw5vox56kuv.ffgz.tsg.suse.edu.cn/showproj.aspx?proj=120931. | Ming Li Bingjie Hao Menghuan Zhang Russel J.Reiter Shumeng Lin Tiansheng Zheng Xiangyun Chen Yanbei Ren Liduo Yue Baigenzhin Abay Guojie Chen Xiao Xu Yufeng Shi Lihong Fan | 2021 | Signal Transduction and Targeted Therapy2021，6，10： | 6 |
| 8 | 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 |

| 10 | Experimental investigation on dynamic response of flat blades with underplatform dampers显示文摘One test rig with three blades and two Under-Platform Dampers(UPDs) is established to better understand the dynamical behavior of blades with UPDs. A pre-loaded spring is used to simulate the centrifugal load acting on the damper, thereby achieving continuous adjustment of the pressing load. UPDs with different forms, sizes and materials are carefully designed as experimental control groups. Noncontact measurement via a laser Doppler velocimeter is employed and contact excitation which is performed by an electromagnetic exciter is adopted to directly obtain the magnitude of the excitation load by a force sensor mounted on the excitation rod. Particular attention is paid to the influence of the contact status of the contact surfaces, e.g. the pressure-sensitive paper is used to measure the effective contact area of the UPDs. The experimental variables are selected as the centrifugal force, the amplitude of the excitation force, the damper mass, the effective contact area, and the damper material. The Frequency Response Function(FRF) of the blade under different experimental parameters is obtained by slow frequency sweep under sinusoidal excitation to study the influence of each parameter on the dynamic characteristics of the blade and the mechanism analysis is carried out combined with the experimental results. | Dayi ZHANG Bin GAO Jie HONG Jianwei FU Xiangyun GE | 2019 | Chinese Journal of Aeronautics2019，32，12： | 5 |
| 11 | 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 |

| 14 | 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 |
| 15 | In vitro comparison of the hemocompatibility of diamond-like carbon and carbon nitride coatings with different atomic percentages of N显示文摘Carbon nitride (CNx) and diamond-like carbon (DLC) coatings were prepared by dc magnetron sputtering at room temperature. Different partial pressures of N2 were used to synthesize CNx to evaluate the relationship between the atomic percentage of nitrogen and hemocompatibility. Auger electron spectroscopy and atomic force microscopy indicated atomic percentages of N of 0.12 and 0.22 and that the CNx coatings were smooth. An in vitro study of the hemocompatibility of the coatings revealed that both CNx coatings had better anticoagulant properties and lower platelet adhesion than DLC. Compared with CN0.12, the CN0.22 coating showed longer dynamic clotting time (about 42 min), static clotting time (23.6 min) and recalcification time (45.6 s), as well as lower platelet adhesion (102 cells μm 2), aggregation, and activation. The presence of nitrogen in the CNx coatings induced their enhanced hemocompatibility compared with DLC. | ZHAO MengLi LI DeJun ZHANG YiTeng GUO MeiXian DENG XiangYun GU HanQing WAN RongXin | 2012 | Science China(Life Sciences)2012，55，4： | 3 |
| 16 | Electronic Structure and Physical Characteristics of Dioxin Under External Electric Field显示文摘Dioxin is a highly toxic and caustic substance,which widely existed in the atmosphere,soil and water with tiny particles.Dioxin pollution has become a major problem that concerns the survival of mankind,which must be strictly controlled.The bond length,bond angle,energy,dipole moment,orbital energy level distribution of dioxin under the external field are investigated using DFT(density functional theory)on basis set level of B3LYP/6-31G(d,p).The results indicate that with the increase of the electric field,the length of one Carbon-Oxygen bond increases while another Carbon-Oxygen bond decreases.The energy gradually decreases with the electric field,while the change of the dipole moment has an opposite trend.In the infrared spectra,the vibration frequency decreases with the electric field increasing and shows an obvious red shift.Moreover,the ultraviolet-visible absorption spectra under different electric fields are analyzed with TD-DFT(time-dependent density functional theory)method.The wavelength of the strongest absorption peak increases and occurs red shift with the increase of the electric field.All the above results can provide reference for further research on the properties of dioxin under different external electric field. | Wenyi Yin Xiangyun Zhang Bumaliya Abulimiti Yuzhu Liu Yihui Yan Fengbin Zhou Feng Jin | 2018 | Computers, Materials & Continua2018，，4： | 2 |
| 17 | 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 |
| 18 | Modeling and Simulation of Packet Delivery Rate in LTE-V Network Based on Markov Chain显示文摘As one of the most promising communication technologies for vehicular networks, LTE-V has the advantages of wide coverage and a high transmission rate. 3 GPP released the technical specification of LTE-V in March 2017, launching a spate of related research and industrialization. In this paper, we propose a communication model based on Markov process to evaluate the reliability of LTE-V. We derived the Packet Delivery Rate(PDR) of LTE-V based on the model. Moreover, we use Poisson process to model the distribution of vehicles on a highway,then combine the communication model with the vehicles’ distribution to derive the PDR under this scenario. To verify the correctness of the proposed model, we established a simulation program on the MATLAB platform. By comparing the simulation results and the mathematical results, we found that simulation results are a very good fit for the model. | Mengkai Shi Yaohan Tang Xiangyun Zhang Yi Zhang Jun Xu | 2020 | Tsinghua Science and Technology2020，25，3： | 2 |
| 19 | 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 |
