| 1 | Recent movement changes of main fault zones in the Sichuan-Yunnan region and their relevance to seismic activity显示文摘The Wenchuan earthquake occurred near the 'triple junction' linking the Bayan Har block, the South China block, and the Sichuan-Yunnan rhombic block, and its influences on the surrounding blocks and the main fault zones in the Sichuan-Yunnan region, i.e., the block boundary zone, cannot be ignored. In this paper, changes of movement and stress of the fault zones before and after a strong earthquake were simulated based on the GPS repetition survey results recently obtained during 1999–2007, 2009–2011, and 2011–2013 with a two-dimensional finite-element contact model and the 'block- loading' method. The results show that, before the Wenchuan earthquake, the movement of the Longmenshan fault zone was very slow and its compressive stress accumulated rapidly; after the Wenchuan earthquake, movements toward the E-SSE direction of the Bayan Har, southwestern Yunnan, and rhombic blocks were enhanced, and the dextral and horizontal compressive speeds and annual accumulative compressive stress of the Longmenshan fault zone increased markedly by factors of 4.5, 2.1, and 2.5, respectively. The southern Xianshuihe, Anninghe, Zemuhe, Daliangshan, and Lijiang-Xiaojinhe fault zones accumulated compressive stress rapidly, forming enhanced compressive stress zones along a NE strike crossing the central part of the Sichuan-Yunnan region. The tensional movement of the Xianshuihe fault zone was enhanced and the slip movement in the central part of the zone was reversed in a short time. The changes are tightly related to the medium-intensity earthquakes that occurred during the same period in this region, revealing that the spatial migration of seismic activity is related to changes of movement of the blocks. | LIU Xia MA Jin DU XueSong ZHU Shuang LI LaYue SUN DongYing | 2016 | Science China Earth Sciences2016，59，6： | 4 |
| 2 | Reduced graphene oxide aerogel decorated with Mo_(2)C nanoparticles toward multifunctional properties of hydrophobicity,thermal insulation and microwave absorption显示文摘Reduced graphene oxide(rGO)aerogels are emerging as very attractive scaffolds for high-performance electromagnetic wave absorption materials(EWAMs)due to their intrinsic conductive networks and intricate interior microstructure,as well as good compatibility with other electromagnetic(EM)components.Herein,we realized the decoration of rGO aerogel with Mo_(2)C nanoparticles by sequential hydrothermal assembly,freeze-drying,and high-temperature pyrolysis.Results show that Mo_(2)C nanoparticle loading can be easily controlled by the ammonium molybdate to glucose molar ratio.The hydrophobicity and thermal insulation of the rGO aerogel are effectively improved upon the introduction of Mo_(2)C nanoparticles,and more importantly,these nanoparticles regulate the EM properties of the rGO aerogel to a large extent.Although more Mo_(2)C nanoparticles may decrease the overall attenuation ability of the rGO aerogel,they bring much better impedance matching.At a molar ratio of 1:1,a desirable balance between attenuation ability and impedance matching is observed.In this context,the Mo_(2)C/r GO aerogel displays strong reflection loss and broad response bandwidth,even with a small applied thickness(1.7 mm)and low filler loading(9.0wt%).The positive effects of Mo_(2)C nanoparticles on multifunctional properties may render Mo_(2)C/r GO aerogels promising candidates for high-performance EWAMs under harsh conditions. | Yahui Wang Minghui Zhang Xuesong Deng Zhigang Li Zongsheng Chen Jiaming Shi Xijiang Han Yunchen Du | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，3： | 2 |
| 3 | IFN-inducible p47 GTPases display differential responses to Schistosoma japonicum acute infection显示文摘Interferon gamma induced GTPase(IGTP)(also named lrgm3)and interferon gamma inducible protein 47(IRG-47)(also named lIrgd)are interferon(IFN)-inducible p47 GTPases that have been shown to regulate host resistance to intracellular pathogens.Little knowledge has been known about the role of p47 GTPases in host responses against extracellular pathogens.To investigate possible roles of IGTP and IRG-47 in the course of Schistosoma japonicum infection,IGTP and IRG-47 knockout and wild-type(WT)mice were challenged with cercariae of S.japonicum,and host responses were analyzed.At the acute stage of S.japonicum infection,mice that lacked IGTP displayed similar parasite burden and pathological damage to WT mice.Importantly,S.japonicum-infected lRG-47-deficient mice,in contrast to IGTP-deficient mice and WT mice,showed significantly reduced worms and lower egg-burden,but intense granulomatous reaction evoked by schistosome eggs in peripheral parts of liver lobes.In addition,upregulation of inflammation-related gene expression was observed in the spleen of IRG-47-deficient mice using oligonucleotide microarrays,in which multiple pathways of cytokine-cytokine receptor interaction,T-cell receptor signaling,complement,coagulation cascades and cell adhesion molecules were highlighted.Taken together,these data suggest that IGTP and IRG-47 might have distinct features that were differentially required for resistance to S.japonicum. | Xuesong Chen Xiaotang Du Meijuan Zhang Donghui Zhang Minjun Ji Guanling Wu | 2010 | Cellular & Molecular Immunology2010，7，1： | 2 |

| 5 | 3D TRANSIENT COUPLED THERMOELASTIC-PLASTIC CONTACT SEALING ANALYSIS OF REACTOR PRESSURE VESSEL显示文摘Sealing analysis of sealing system in reactor pressure vessels is relevant with multiple nonlinear coupled-field effects, so even large-scale commercial finite element software cannot finish the complicated analysis. A fmite element method of 3D transient coupled thermo-elastic-plastic contact sealing analysis for reactor pressure vessels is presented, in which the surface nonlinearity,material nonlinearity, transient heat transfer nonlinearity and multiple coupled effect are taken into account and the sealing equation is coupling solved in iterative procedure. At the same time, a computational analysis program is developed, which is applied in the sealing analysis of experimental reactor pressure vessel, and the numerical results are in good coincidence with the experimental results. This program is also successful in analyzing the practical problem in engineering. | Du Xuesong Li Runfang Lin Tengjiao | 2005 | Chinese Journal of Mechanical Engineering2005，18，4： | 2 |

| 7 | Does independent directors' monitoring affect reputation? Evidence from the stock and labor markets显示文摘Using novel data on independent directors' opinions in China, we investigate the stock and labor market effects prompted by independent directors publicly saying ‘‘no' to major board decisions. We find that the market reacts negatively to modified director opinions, but positively to firms interlocked with the directors who said ‘‘no.' We further find substantial turnover and decline in board seats after independent directors issue modified opinions. Overall, we identify a dilemma in China whereby the labor market does not reward vigilant directors for standing up to firm insiders, although investors add a premium to effective board monitoring. | Jun Du Qingchuan Hou Xuesong Tang Yiwei Yao | 2018 | China Journal of Accounting Research2018，，2： | 1 |

| 9 | An Anti-Quantum Authentication Protocol for Space Information Networks Based on Ring Learning with Errors显示文摘With the continuous development of satellite communication and Internet of things technology,more and more devices can access space information networks(SIN)and enjoy satellite services everywhere in the world.However,due to the openness of the air-to-ground channel,the device will face a series of security threats when accessing SIN,such as replay attacks,eavesdropping attacks,impersonation attacks,and man-in-the-middle attacks.These security threats will lead to illegal entity access and further endanger the reliability and availability of the system.Although scholars have proposed many enhanced security access authentication protocols,most of them have been proved to have security vulnerabilities.In addition,with the development of quantum computing,the previous authentication protocols based on some asymmetric cryptographic mechanisms such as discrete logarithm and elliptic curve cryptographic mechanisms may face new security challenges.In this context,this paper proposes a novel antiquantum access authentication protocol based on ring learning with errors(RLWE),which meets more security requirements and greatly reduces the authentication delay through prenegotiation.Through the security analysis and performance analysis,it is shown that our protocol can be more suitable for delaysensitive IoT devices to access SIN while ensuring higher security. | Junyan Guo Ye Du Xuesong Wu Meihong Li | 2021 | Journal of Communications and Information Networks2021，6，3： | 0 |

| 11 | Three-Dimensional Conjugate Tooth Surface Design and Contact Analysis of Harmonic Drive with Double-Circular-Arc Tooth Profle显示文摘A three-dimensional conjugate tooth surface design method for Harmonic Drive with a double-circular-arc tooth profle is proposed. The radial deformation function of the fexspline (FS), obtained through Finite Element (FE) analysis, is incorporated into the kinematics model. By analyzing the FS tooth enveloping process, the optimization of the overlapping conjugate tooth profle is achieved. By utilizing the hobbing process, the three-dimensional machinable tooth surface of FS can be acquired. Utilizing the coning deformation of the FS, simulations are conducted to analyze the multi-section assembly and meshing motion of the machinable tooth surface. The FE method is utilized to analyze and compare the loaded contact characteristics. Results demonstrate that the proposed design method can achieve an internal gear pair consisting of a circular spline with a spur gear tooth surface and the FS with a machinable tooth surface. With the rated torque, approximately 24% of the FS teeth are engaged in meshing, and more than 4/5 of the tooth surface in the axial direction carries the load. The contact patterns, maximum contact pressure, and transmission error of the machinable tooth surface are 227.2%, 40.67%, and 71.24% of those on the spur gear tooth surface, respectively. It clearly demonstrates exceptional transmission performance. | Chaosheng Song Feihong Zhu Xinzi Li Xuesong Du | 2023 | Chinese Journal of Mechanical Engineering2023，36，5： | 0 |
| 12 | The Application of GNSS to Fault Deformation Studies显示文摘Great earthquakes often occur along or near active fault belts. Thus,monitoring and research on fault deformation are quite important. Methods such as short-leveling,shortbaseline and integrated monitoring profile across fault belts have been used to monitor fault activities for many years. GNSS observations are mainly used to obtain the horizontal velocity field in large areas and to study the activities and deformation of major blocks.GNSS technology has been used to monitor and study the deformation of faults from a different aspects. In this paper,some applications and new explorations of GNSS are discussed. They are:( 1) Research and monitoring of strike-slip activities of faults with GNSS.( 2) Research and monitoring of vertical activities of faults with GNSS.( 3)Investigating the laws of deformation of blocks on the sides of fault zone and setting up strain models to deduce the activities and deformation of faults with respective models and compare the deduced results with the actual measurements across fault. It is concluded that a larger discrepancy between the deduced and the observed deformation indicates a stronger interaction between the blocks,which can be important for predicting the location of a strong earthquake and assessing seismic hazard,as well as the seismicity trend. | Bo Wanju Feng Shengtao Su Jianfeng Zhou Haitao Du Xuesong Wan Wenni Liu Tianhai | 2014 | Earthquake Research in China2014，28，4： | 0 |

| 14 | Trogocytosis of CAR molecule regulates CAR-T cell dysfunction and tumor antigen escape显示文摘Chimeric antigen receptor(CAR)T-cell therapy has demonstrated clinical response in treating both hematologic malignancies and solid tumors.Although instances of rapid tumor remissions have been observed in animal models and clinical trials,tumor relapses occur with multiple therapeutic resistance mechanisms.Furthermore,while the mechanisms underlying the long-term therapeutic resistance are well-known,short-term adaptation remains less understood.However,more views shed light on short-term adaptation and hold that it provides an opportunity window for long-term resistance.In this study,we explore a previously unreported mechanism in which tumor cells employ trogocytosis to acquire CAR molecules from CAR-T cells,a reversal of previously documented processes.This mechanism results in the depletion of CAR molecules and subsequent CAR-T cell dysfunction,also leading to short-term antigen loss and antigen masking.Such type of intercellular communication is independent of CAR downstream signaling,CAR-T cell condition,target antigen,and tumor cell type.However,it is mainly dependent on antigen density and CAR sensitivity,and is associated with tumor cell cholesterol metabolism.Partial mitigation of this trogocytosis-induced CAR molecule transfer can be achieved by adaptively administering CAR-T cells with antigen density-individualized CAR sensitivities.Together,our study reveals a dynamic process of CAR molecule transfer and refining the framework of clinical CAR-T therapy for solid tumors. | You Zhai Yicong Du Guanzhang Li Mingchen Yu Huimin Hu Changqing Pan Di Wang Zhongfang Shi Xu Yan Xuesong Li Tao Jiang Wei Zhang | 2024 | Signal Transduction and Targeted Therapy2024，9，1： | 0 |
