| 1 | Morphological, mechanical and thermal properties of cyanate ester/benzoxazine resin composites reinforced by silane treated natural hemp fibers显示文摘This present study deals with the reinforcement of thermosetting resin blends composed of cyanate ester(CE) and benzoxazine(BOZ) resins with natural hemp fibers(NHFs). These NHFs were initially treated by using a silane coupling agent(SCA) in order to chiefly enhance their distributions as well as adhesions within the CE/BOZ resin matrix,then incorporated with various weight amounts ranging from 5 wt% to 20 wt% with a regular interval of 5 wt%. The obtained results showed that at the maximum treated fiber loading(20 wt%), distinctive enhancements in the mechanical properties in terms of flexural strength and microhardness were obtained. Besides, the thermal stability and glass transition temperature(Tg) were appreciably enhanced and were higher than those of the pure CE/BOZ resin properties. With respect to the astonishing properties of the NHFs, these enhancements could be possibly due to the good dispersion and adhesion of the treated NHFs inside the CE/BOZ resin achieved upon using the SCA. Therefore,we believe herein that these renewable and cheap NHFs have considerable potential to be used as reinfocer materials for CE/BOZ resin composites to be used in various industrial sectors. | Abdeldjalil Zegaoui Ruikun Ma Abdul Qadeer Dayo Mehdi Derradji Jun Wang Wenben Liu Yile Xu Wan'an Cai | 2018 | Chinese Journal of Chemical Engineering2018，26，5： | 4 |
| 2 | SARS-CoV-2 cell entry and targeted antiviral development显示文摘Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)is the causative agent of the pandemic coronavirus disease 2019(COVID-19),which threatens human health and public safety.In the urgent campaign to develop anti-S ARS-CoV-2 therapies,the initial entry step is one of the most appealing targets.In this review,we summarize the current understanding of SARS-CoV-2 cell entry,and the development of targeted antiviral strategies.Moreover,we speculate upon future directions toward nextgeneration of SARS-CoV-2 entry inhibitors during the upcoming post-pandemic era. | Zinuo Chen Ruikun Du Jazmin M.Galvan Achi Lijun Rong Qinghua Cui | 2021 | Acta Pharmaceutica Sinica B2021，11，12： | 3 |
| 3 | Adaptive nonsingular fast terminal sliding mode control for underwater manipulator robotics with asymmetric saturation actuators显示文摘In this paper,an adaptive nonsingular fast terminal sliding mode control(ANFTSMC)is proposed for underwater manipulator robotics with asymmetric actuator saturations and unknown time-varying(TV)external disturbances.Firstly,the nonsingular fast terminal sliding mode(NFTSM)control scheme is conducted for the underwater manipulator robotics,which guarantees the boundedness of all the signals in the control system.Secondly,the adaptive method and the smooth hyperbolic tangent(tanh)function are introduced to address the unknown TV external disturbances and the input saturation errors.Thus the prior knowledge about the upper bounds of the system uncertainties is not needed in this paper.To deal with the nonlinear asymmetric input saturation issue,a Gaussian error function is employed in the asymmetric saturation module so that the discontinuous input signals can be transformed into smooth forms.Thirdly,the rigorous mathematical verification is conducted to demonstrate the stability and finite-time convergence of the closed-loop control system via the Lyapunov theory.Finally,numerical simulations are performed on a two-link underwater manipulator robotic system to illustrate the effectiveness of the proposed controller. | Zeng cheng ZHOU Guoyuan TANG Hui HUANG Lijun HAN Ruikun XU | 2020 | Control Theory and Technology2020，18，1： | 2 |
| 4 | Vibration analysis of a single row angular contact ball bearing with the coupling errors including the surface roundness and waviness显示文摘Roundness and surface waviness are main manufacturing errors on the components of single row angular contact ball bearings(ACBBs).An analytical study for vibrations of the ACBBs with coupling errors including the roundness and waviness can be useful for the vibration control of the rotating machinery.However,most previous works only focused on the single error modelling method.In this paper,an improved time dependent displacement excitation(TDDE)model is proposed to consider the coupling errors including the roundness and waviness on the inner and outer races of an ACBB.The TDDE model for the roundness and waviness is established by using a combination of several sinusoidal functions.A dynamic model in the previous study is improved to consider the influences of coupling errors including the roundness and waviness.The Hertzian contact theory and Dowson’s method are adopted to calculate the bearing contact stiffness.The time-and frequency-domain vibrations for the experimental and simulation results are compared to show some model validation.The influences of roundness orders and waviness amplitudes on the vibrations of the ACBB are analysed.The obtained results show that the coupling errors including the roundness and waviness have some influence on the time-domain impulse waveform and frequency-domain spectrum characteristics of the bearing accelerations.The differences of the vibrations between the coupling errors and sing error are from 4%to 42%.This paper can provide a useful guidance for the accurate diagnosis of surface imperfections in the ACBBs. | LIU Jing PANG RuiKun XU YaJun DING ShiZhao HE QuBo | 2020 | Science China(Technological Sciences)2020，63，6： | 2 |

| 11 | Multi-Layer Reconstruction Errors Autoencoding and Density Estimate for Network Anomaly Detection显示文摘Anomaly detection is an important method for intrusion detection.In recent years,unsupervised methods have been widely researched because they do not require labeling.For example,a nonlinear autoencoder can use reconstruction errors to attain the discrimination threshold.This method is not effective when the model complexity is high or the data contains noise.The method for detecting the density of compressed features in a hidden layer can be used to reduce the influence of noise on the selection of the threshold because the density of abnormal data in hidden layers is smaller than normal data.However,compressed features may lose some of the high-dimensional distribution information of the original data.In this paper,we present an efficient anomaly detection framework for unsupervised anomaly detection,which includes network data capturing,processing,feature extraction,and anomaly detection.We employ a deep autoencoder to obtain compressed features and multi-layer reconstruction errors,and feeds them the same to the Gaussian mixture model to estimate the density.The proposed approach is trained and tested on multiple current intrusion detection datasets and real network scenes,and performance indicators,namely accuracy,recall,and F1-score,are better than other autoencoder models. | Ruikun Li Yun Li Wen He Lirong Chen Jianchao Luo | 2021 | Computer Modeling in Engineering & Sciences2021，，7： | 1 |
| 12 | Pyrolysis transformation of ZIF-8 wrapped with polytriazine to nitrogen enriched core-shell polyhedrons carbon for supercapacitor显示文摘This work presents a simple effective strategy to synthesize N-doped and shell-controlled carbon nanocages through a package baking approach.A green approach to synthesize core-shell ZIF-8@PTZ nanoparticles involves zinc contained ZIF-8 core wrapped by a N-enriched polytriazine(PTZ).Synthesized core-shell ZIF-8@PTZ nanoparticles are calcinated to further sublime zinc through PTZ shell and washed by HC1,leaving a porous carbon structure.At the meantime,hollow cavities were introduced into N-doped carbon polyhedrons via the sacrifice of ZIF-8 template(noted as ZIF-8@C/N-x).The electrochemical performance of the ZIF-8@C/N-x as supercapacitor electrode has demonstrated high energy density and specific capacitance,as well as a long-term cycleability showing 92%capacitance retention after 10000 cycles.There is a systematic correlation between micro-/meso-porosity of ZIF-8@C/N-x and their electrochemical performances. | Nuoya Wang Xinhua Huang Lei Zhang Jinsong Hu Yimin Chao Ruikun Zhao | 2021 | Frontiers of Chemical Science and Engineering2021，15，4： | 1 |

| 18 | MAGNETIC DOMAIN STRUCTURE AND RELATED MAGNETIC PROPERTIES OF(NdPr)_(16)Fe_(76)B_8 PERMANENT MAGNET显示文摘The magnetic domain structure and related magnetic properties of (NdPr)16Fe76B8 permanentmagnet have been studied by colloid-SEM method.In thermally demagnetized state,the ma-trix grains in the magnet generally exhibit multidomain structure,i.e.,180° plate-like indi-vidual domain and a few spike-like or maze-like domains.The average width of the domainmeasured was 1.5μm.Grain size of single-domain was observed to be generally about 1μmand only a few up to 3μm.The results calculated are:the domain wall energy γ=36MJ/m2,the exchange constant A=4.5×10-11J/m,the domain wall width δ=15.7nm,and the critical grain diameter of single-domain Dc=0.5μm.The dependence of high magnet-ic field gradient at grain boundaries in different magnetization directions in the adjacent mag-netic domains located on both sides of grain boundaries and the effect of microstructure on thevalues of K,A and δ were discussed. | WANG Ruikun SUN Lihong LI Dongpei YING Qiming | 1989 | Acta Metallurgica Sinica(English Letters)1989，2，8： | 0 |
| 19 | Allopregnanolone targets nucleoprotein as a novel influenza virus inhibitor显示文摘Influenza A virus(IAV)poses a global public health concern and remains an imminent threat to human health.Emerging antiviral resistance to the currently approved influenza drugs emphasizes the urgent need for new therapeutic entities against IAV.Allopregnanolone(ALLO)is a natural product that has been approved as an antidepressant drug.In the present study,we repurposed ALLO as a novel inhibitor against IAVs.Mechanistic studies demonstrated that ALLO inhibited virus replication by interfering with the nucleus translocation of viral nucleoprotein(NP).In addition,ALLO showed significant synergistic activity with compound 16,a hemagglutinin inhibitor of IAVs.In summary,we have identified ALLO as a novel influenza virus inhibitor targeting NP,providing a promising candidate that deserves further investigation as a useful anti-influenza strategy in the future. | Meiyue Dong Yanyan Wang Ping Li Zinuo Chen Varada Anirudhan Qinghua Cui Lijun Rong Ruikun Du | 2023 | Virologica Sinica2023，38，6： | 0 |
