1Role of plant autophagy in stress response显示文摘Autophagy is a conserved pathway for the bulk degradation of cytoplasmic components in all eukaryotes.This process plays a critical role in the adaptation of plants to drastic changing environmental stresses such as starvation,oxidative stress,drought,salt,and pathogen invasion.This paper summarizes the current knowledge about the mechanism and roles of plant autophagy in various plant stress responses.Shaojie Han Bingjie Yu Yan Wang Yule Liu 2011Protein & Cell2011,2,10:15
2NLRP3-dependent pyroptosis is required for HIV-1 gp120- induced neuropathology显示文摘The human immunodeficiency virus-1(HIV-1)envelope protein gp120 is the major contributor to the pathogenesis of HIVassociated neurocognitive disorder(HAND).Neuroinflammation plays a pivotal role in gp120-induced neuropathology,but how gp120 triggers neuroinflammatory processes and subsequent neuronal death remains unknown.Here,we provide evidence that NLRP3 is required for gp120-induced neuroinflammation and neuropathy.Our results showed that gp120-induced NLRP3-dependent pyroptosis and IL-1βproduction in microglia.Inhibition of microglial NLRP3 inflammasome activation alleviated gp120-mediated neuroinflammatory factor release and neuronal injury.Importantly,we showed that chronic administration of MCC950,a novel selective NLRP3 inhibitor,to gp120 transgenic mice not only attenuated neuroinflammation and neuronal death but also promoted neuronal regeneration and restored the impaired neurocognitive function.In conclusion,our data revealed that the NLRP3 inflammasome is important for gp120-induced neuroinflammation and neuropathology and suggest that NLRP3 is a potential novel target for the treatment of HAND.Xiaolong He Weijun Yang Zhijie Zeng Yi Wei Jie Gao Bao Zhang Li Li Liqun Liu Yu Wan Qing Zeng Zelong Gong Liting Liu Hanyun Zhang Yubin Li Shaojie Yang Tongtong Hu Lixian Wu Eliezer Masliah Shenghe Huang Hong Cao 2020Cellular & Molecular Immunology2020,17,3:11
3Dynamically controlling terahertz wavefronts with cascaded metasurfaces显示文摘Dynamically controlling terahertz(THz)wavefronts in a designable fashion is highly desired in practice.However,available methods working at microwave frequencies do not work well in the THz regime due to lacking suitable tunable elements with submicrometer sizes.Here,instead of locally controlling individual meta-atoms in a THz metasurface,we show that rotating different layers(each exhibiting a particular phase profile)in a cascaded metadevice at different speeds can dynamically change the effective Jonesmatrix property of the whole device,thus enabling extraordinary manipulations on the wavefront and polarization characteristics of a THz beam impinging on the device.After illustrating our strategy based on model calculations,we experimentally demonstrate two proof-of-concept metadevices,each consisting of two carefully designed all-silicon transmissive metasurfaces exhibiting different phase profiles.Rotating two metasurfaces inside the fabricated devices at different speeds,we experimentally demonstrate that the first metadevice can efficiently redirect a normally incident THz beam to scan over a wide solid-angle range,while the second one can dynamically manipulate both the wavefront and polarization of a THz beam.Our results pave the way to achieving dynamic control of THz beams,which is useful in many applications,such as THz radar,and bio-and chemical sensing and imaging.Xiaodong Cai Rong Tang Haoyang Zhou Qiushi Li Shaojie Ma Dongyi Wang Tong Liu Xiaohui Ling Wei Tan Qiong He Shiyi Xiao Lei Zhou 2021Advanced Photonics2021,3,3:8
4Simulation analysis theory and experimental verification of air-cushion isolation control of high concrete dams显示文摘To focus on the key scientific problem of process control of dynamic catastrophe of high dams,presented for the first time are the modelling theory of liquid-gas-solid tri-phase coupling of the air-cushion isolation control of high dams and its numerical simulation method,and theoretical description of the complicated dynamics problem of the tri-phase coupling-thermodynamics state-material-contact bi-nonlinearity,as well as the simulation analysis of the key effects of dynamic catastrophe of the air-cushion isolated high dam engineering.The analytic solution of plane-wave with rigid-dam body was created.The simulation comparison of dynamic catastrophe processes of 305 m Jinping arch dam with and without seismic control was carried out,and the results were basically in agreement with that obtained from the large shaking table tests,and verify each other.The entire air-chamber and optimized air-cushion with varying thickness were presented to develop a optimization method.The large shaking table tests of the isolated dam model,which is satisfied with the basic dynamic similarity relations,were performed for the first time.The test data seemed to be convincing and were in agreement with the dynamic simulation results of the tested model,thereby providing an experimental verification to the simulation theory and method.The combination experiments of theoretical model and physical model demonstrated that the hydrodynamic pressure of high arch dams can be reduced by more than 70% as well as the first and third principle stresses of the dam body reduced by more than 20%-30%,thereby the global anti-seismic capacity of the high dam being improved significantly.The results have shown that the air-cushion isolation is the prior developing direction of structural control technology of high concrete dams.LIU HaoWu ZHANG ShaoJie CHEN Jiang SUN Man SUN Lei LI Yi 2011Science China(Technological Sciences)2011,54,11:6
5Topologically Protected Edge State in Two-Dimensional Su–Schrieffer–Heeger Circuit显示文摘Topological circuits,an exciting feld just emerged over the last two years,have become a very accessible platform for realizing and exploring topological physics,with many of their physical phenomena and potential applications as yet to be discovered.In this work,we design and experimentally demonstrate a topologically nontrivial band structure and the associated topologically protected edge states in an RF circuit,which is composed of a collection of grounded capacitors connected by alternating inductors in the x and y directions,in analogy to the Su–Schriefer–Heeger model.We take full control of the topological invariant(i.e.,Zak phase)as well as the gap width of the band structure by simply tuning the circuit parameters.Excellent agreement is found between the experimental and simulation results,both showing obvious nontrivial edge state that is tightly bound to the circuit boundaries with extreme robustness against various types of defects.Te demonstration of topological properties in circuits provides a convenient and fexible platform for studying topological materials and the possibility for developing fexible circuits with highly robust circuit performance.Shuo Liu Wenlong Gao Qian Zhang Shaojie Ma Lei Zhang Changxu Liu Yuan Jiang Xiang Tie Jun Cui Shuang Zhang 2019Research2019,,1:6
6Deterministic Approach to Achieve Full-Polarization Cloak显示文摘Achieving full-polarization(σ)invisibility on an arbitrary three-dimensional(3D)platform is a long-held knotty issue yet extremely promising in real-world stealth applications.However,state-of-the-art invisibility cloaks typically work under a specific polarization because the anisotropy and orientation-selective resonant nature of artificial materials made theσ-immune operation elusive and terribly challenging.Here,we report a deterministic approach to engineer a metasurface skin cloak working under an arbitrary polarization state by theoretically synergizing two cloaking phase patterns required,respectively,at spin-up(σ+)and spin-down(σ−)states.Therein,the wavefront of any light impinging on the cloak can be well preserved since it is a superposition ofσ+andσ−wave.To demonstrate the effectiveness and applicability,several proof-of-concept metasurface cloaks are designed to wrap over a 3D triangle platform at microwave frequency.Results show that our cloaks are essentially capable of restoring the amplitude and phase of reflected beams as if light was incident on a flat mirror or an arbitrarily predesigned shape under full polarization states with a desirable bandwidth of~17.9%,conceiving or deceiving an arbitrary object placed inside.Our approach,deterministic and robust in terms of accurate theoretical design,reconciles the milestone dilemma in stealth discipline and opens up an avenue for the extreme capability of ultrathin 3D cloaking of an arbitrary shape,paving up the road for real-world applications.He-Xiu Xu Yanzhao Wang Chaohui Wang Mingzhao Wang Shaojie Wang Fei Ding Yongjun Huang Xiaokuan Zhang Haiwen Liu Xiaohui Ling Wei Huang 2021Research2021,,1:5
7Novel robust control framework for morphing aircraft显示文摘This paper develops a robust control methodology for a class of morphing aircraft,which is called innovative control effector(ICE) aircraft.For the ICE morphing aircraft,the distributed arrays of hundreds of shape-change devices are employed to stabilize and maneuver the air vehicle.Because the morphing aircraft have the inherent uncertainty and varying dynamics due to the alteration of their configuration,a desired control performance can not be satisfied with a fixed feedback controller.Therefore,a novel control framework including an adaptive flight control law and an adaptive allocation algorithm is proposed.Firstly,a state feedback adaptive control law is designed to guarantee closed-loop stability and state tracking in the presence of uncertain dynamics caused by the wing shape change due to different flight missions.In the control allocation,many distributed arrays are managed in an optimal way to improve the robustness of the system.The scheme is used to an uncertain morphing aircraft model,and the simulation results demonstrate their performance.Chunsheng Liu Shaojie Zhang 2013Journal of Systems Engineering and Electronics2013,24,2:4
8A Model of Debris Flow Forecast Based on the Water-Soil Coupling Mechanism显示文摘Debris flow forecast is an important means of disaster mitigation. However, the accuracy of the statistics-based debris flow forecast is unsatisfied while the mechanism-based forecast is unavailable at the watershed scale because most of existing researches on the initiation mechanism of debris flow took a single slope as the main object. In order to solve this problem, this paper developed a model of debris flow forecast based on the water-soil coupling mechanism at the watershed scale. In this model, the runoff and the instable soil caused by the rainfall in a watershed is estimated by the distributed hydrological model(GBHM) and an instable identification model of the unsaturated soil. Because the debris flow is a special fluid composed of soil and water and has a bigger density, the density estimated by the runoff and instable soil mass in a watershed under the action of a rainfall is employed as a key factor to identify the formation probability of debris flow in the forecast model. The Jiangjia Gulley, a typical debris flow valley with a several debris flow events each year, is selected as a case study watershed to test this forecast model of debris flow. According the observation data of Dongchuan Debris Flow Observation and Research Station, CAS located in Jiangjia Gulley, there were 4 debris flow events in 2006. The test results show that the accuracy of the model is satisfied.Shaojie Zhang Hongjuan Yang Fangqiang Wei Yuhong Jiang Dunlong Liu 2014Journal of Earth Science2014,25,4:4
9Amino-functionalized porous PDVB with high adsorption and regeneration performance for fluoride removal from water显示文摘Excessive fluoride anions in drinking water are toxic to the health of human beings.In this article,an effective fluoride removal adsorbent on the basis of amino-functionalized porous polydivinylbenzene(PDVB)was prepared through low cost processes,which included solvothermal preparation of porous PDVB and subsequent surface amino-functionalization.The obtained amino-functionalized porous PDVB(A-PDVB)has high surface area of 443 m2 g1 and high adsorption capacity towards fluoride anion up to 105.9 mg g1.Considering adsorbents surface area,the adsorption capacity per unit surface area of A-PDVB is 0.24 mg m2 which is more than 4 times of porous PDVB(0.058 mg m2).The enhanced adsorption performance of A-PDVB was due to amino groups electrostatic interaction coupled with hydrogen bond binding with fluoride anions.In addition,the aminofunctionalized porous PDVB could be regenerated in high efficiency under alkaline conditions.This work not only exhibits the possibility of A-PDVB for application as an environment-friendly adsorbent for fluoride removal but also gives an insight into understanding mechanism of the fluoride anions adsorption onto aminofunctionalized porous PDVB.Yuanyuan Huang Xianbiao Wang Yongfei Xu Shaojie Feng Jin Liu Huanting Wang 2021Green Chemical Engineering2021,2,2:4

11Octupole corner state in a three-dimensional topological circuit显示文摘Higher-order topological insulators(HOTIs)represent a new family of topological materials featuring quantized bulk polarizations and zero-dimensional corner states.In recent years,zero-dimensional corner states have been demonstrated in two-dimensional systems in the form of quadrupole modes or dipole modes.Due to the challenges in designing and constructing three-dimensional systems,octupole corner modes in 3D have not been observed.In this work,we experimentally investigate octupole topological phases in a three-dimensional electrical circuit,which can be viewed as a cubic lattice version of the Hofstadter model with aπ-flux threading each plaquette.We experimentally observe in our higher-order topological circuit a 0D corner state manifested as a localized impedance peak.The observed corner state in the electrical circuit is induced by the octupole moment of the bulk circuit and is topologically protected by anticommuting spatial symmetries of the circuit lattice.Our work provides a platform for investigating higher-order topological effects in three-dimensional electrical circuits.Shuo Liu Shaojie Ma Qian Zhang Lei Zhang Cheng Yang Oubo You Wenlong Gao Yuanjiang Xiang Tie Jun Cui Shuang Zhang 2020Light(Science & Applications)2020,9,1:3

14Recent Development in Numerical Simulation of Enhanced Geothermal Reservoirs显示文摘This paper briefly introduces the current state in computer modelling of geothermal reservoir system and then focuses on our research efforts in high performance simulation of enhanced geothermal reservoir system. A novel supercomputer simulation tool has been developing towards simulating the highly non-linear coupled geomechanical-fluid flow-thermal systems involving heterogeneously fractured geomaterials at different spatial and temporal scales. It is applied here to simulate and visualise the enhanced geothermal system(EGS),such as(1) visualisation of the microseismic events to monitor and determine where/how the underground rupture proceeds during a hydraulic stimulation,to generate the mesh using the recorded data for determining the domain of the ruptured zone and to evaluate the material parameters(i.e.,the permeability) for the further numerical analysis and evaluation of the enhanced geothermal reservoir;(2) converting the available fractured rock image/fracture data as well as the reservoir geological geometry to suitable meshes/grids and further simulating the fluid flow in the complicated fractures involving the detailed description of fracture dimension and geometry by the lattice Boltzmann method and/or finite element method;(3) interacting fault system simulation to determine the relevant complicated rupture process for evaluating the geological setting and the in-situ reservoir properties;(4) coupled thermo-fluid flow analysis of a geothermal reservoir system for an optimised geothermal reservoir design and management. A few of application examples are presented to show its usefulness in simulating the enhanced geothermal reservoir system.Huilin Xing Yan Liu Jinfang Gao Shaojie Chen 2015Journal of Earth Science2015,26,1:2
15Non-Hermitian Skin Effect in a Non-Hermitian Electrical Circuit显示文摘The conventional bulk-boundary correspondence directly connects the number of topological edge states in a finite system with the topological invariant in the bulk band structure with periodic boundary condition(PBC).However,recent studies show that this principle fails in certain non-Hermitian systems with broken reciprocity,which stems from the non-Hermitian skin effect(NHSE)in the finite system where most of the eigenstates decay exponentially from the system boundary.In this work,we experimentally demonstrate a 1D non-Hermitian topological circuit with broken reciprocity by utilizing the unidirectional coupling feature of the voltage follower module.The topological edge state is observed at the boundary of an open circuit through an impedance spectra measurement between adjacent circuit nodes.We confirm the inapplicability of the conventional bulk-boundary correspondence by comparing the circuit Laplacian between the periodic boundary condition(PBC)and open boundary condition(OBC).Instead,a recently proposed non-Bloch bulk-boundary condition based on a non-Bloch winding number faithfully predicts the number of topological edge states.Shuo Liu Ruiwen Shao Shaojie Ma Lei Zhang Oubo You Haotian Wu Yuan Jiang Xiang Tie Jun Cui Shuang Zhang 2021Research2021,,1:2

18In situ growth of a-few-layered MoS_(2)on CdS nanorod for high efficient photocatalytic H_(2)production显示文摘An ultrathin MoS_(2)was grown on CdS nanorod by a solid state method using sulfur powder as sulfur source for photocatalytic H_(2)production.The characterization result reveals that the ultrathin MoS_(2)nanosheets loaded on CdS has a good contact state.The photoelectrochemical result shows that MoS_(2)not only are beneficial for charge separation,but also works as active sites,thus enhancing photocatalytic activity.Compared with pure CdS,the photocatalytic activity of MoS_(2)loaded CdS was significantly improved.The hydrogen evolution rate on m(MoS_(2)):m(CdS)=1:50(m is mass)reaches 542μmol/h,which is 6 times of that on pure CdS(92μmol/h).This work provides a new design for photocatalysts with high photocatalytic activities and provides a deeper understanding of the effect of MoS_(2)on enhancing photocatalytic activity.Wei CHEN Xiang LIU Shaojie WEI Qianqian HENG Binfen WANG Shilong LIU Li GAO Liqun MAO 2021Frontiers in Energy2021,15,3:1

The luminescence, mole fraction quenching and thermal stability of Ba2Ca(BO3)2:Dy3+ were investigated. According to the phase composition analyzed by X-ray powder diffraction, there is no crystalline phase except Ba2Ca(BO3)2 in the sample. Ba2Ca(BO3)2:Dy3+ can produce white emission under 348 nm excitation. The emission intensities of Ba2Ca(BO3)2:Dy3+ are affected by Dy3+ concentration. The concentration quenching effect was analyzed, and the concentration quenching mechanism was verified as dipole-dipole interaction. The critical distance(R c) obtained based on the crystal structure data is 2.911 nm. At 150℃, the emission intensity of Ba2Ca(BO3)2:Dy3+ is 68.0% of the initial value at room temperature. The activation energy for the thermal quenching calculated is 0.202 e V. Moreover, the CIE chromaticity coordinates of Ba2Ca(BO3)2:Dy3+ locate in the white region of(0.319, 0.356).SONG Huiling ZHOU Fen CAO Heying GUO Mingchao ZHAO Jiawei WANG Zhijun LIU Haiyan GAO Shaojie LI Panlai 2015Journal of the Chinese Ceramic Society2015,,2:1
