| 1 | PVT v2:Improved baselines with Pyramid Vision Transformer显示文摘Transformers have recently lead to encouraging progress in computer vision.In this work,we present new baselines by improving the original Pyramid Vision Transformer(PVT v1)by adding three designs:(i)a linear complexity attention layer,(ii)an overlapping patch embedding,and(iii)a convolutional feed-forward network.With these modifications,PVT v2 reduces the computational complexity of PVT v1 to linearity and provides significant improvements on fundamental vision tasks such as classification,detection,and segmentation.In particular,PVT v2 achieves comparable or better performance than recent work such as the Swin transformer.We hope this work will facilitate state-ofthe-art transformer research in computer vision.Code is available at http://gffzz188fe103f8f1460asxcbvw05np6pn6qwq.ffgz.tsg.suse.edu.cn/whai362/PVT. | Wenhai Wang Enze Xie Xiang Li Deng-Ping Fan Kaitao Song Ding Liang Tong Lu Ping Luo Ling Shao | 2022 | Computational Visual Media2022，8，3： | 30 |
| 2 | Rotary unmanned aerial vehicles path planning in rough terrain based on multi-objective particle swarm optimization显示文摘This paper presents a path planning approach for rotary unmanned aerial vehicles(R-UAVs)in a known static rough terrain environment.This approach aims to find collision-free and feasible paths with minimum altitude,length and angle variable rate.First,a three-dimensional(3D)modeling method is proposed to reduce the computation burden of the dynamic models of R-UAVs.Considering the length,height and tuning angle of a path,the path planning of R-UAVs is described as a tri-objective optimization problem.Then,an improved multi-objective particle swarm optimization algorithm is developed.To render the algorithm more effective in dealing with this problem,a vibration function is introduced into the collided solutions to improve the algorithm efficiency.Meanwhile,the selection of the global best position is taken into account by the reference point method.Finally,the experimental environment is built with the help of the Google map and the 3D terrain generator World Machine.Experimental results under two different rough terrains from Guilin and Lanzhou of China demonstrate the capabilities of the proposed algorithm in finding Pareto optimal paths. | XU Zhen ZHANG Enze CHEN Qingwei | 2020 | Journal of Systems Engineering and Electronics2020，31，1： | 20 |
| 3 | Microbiologically influenced corrosion behavior of S32654 super austenitic stainless steel in the presence of marine Pseudomonas aeruginosa biofilm显示文摘S32654 super austenitic stainless steel(SASS) is widely used in highly corrosive environments. However,its microbiologically influenced corrosion(MIC) behavior has not been reported yet. In this study, the corrosion behavior of S32654 SASS caused by a corrosive marine bacterium Pseudomonas aeruginosa was investigated using electrochemical measurements and surface analysis techniques. It was found that P. aeruginosa biofilm accelerated the corrosion rate of S325654 SASS, which was demonstrated by a negative shift of the open circuit potential(EOCP), a decrease of polarization resistance and an increase of corrosion current density in the culture medium. The largest pit depth of the coupons exposed in the P.aeruginosa broth for 14 days was 2.83 m, much deeper than that of the control(1.33 m) in the abiotic culture medium. It was likely that the P. aeruginosa biofilm catalyzed the formation of CrO_3, which was detrimental to the passive film, resulting in MIC pitting corrosion. | Huabing Li Chuntian Yang Enze Zhou Chunguang Yang Hao Feng Zhouhua Jiang Dake Xu Tingyue Gu Ke Yang | 2017 | Journal of Materials Science & Technology2017，33，12： | 10 |
| 4 | Solidification Behavior and Segregation of Re-containing Cast Ni-base Superalloy with Different Cr Content显示文摘The effect of chromium(Cr) on solidification and segregation behavior of Re-containing cast Ni-base superalloys was investigated by optical microscopy(OM),scanning electron microscopy(SEM) and electronic probe micro analysis(EPMA).The results show that Cr has significant effect on solidification and segregation behavior of Re-containing cast Ni-base superalloys.The liquidus and solidus of alloy decrease with increasing Cr in alloys.The segregation coefficient(K) of Mo increases and that of W and Re decreases gradually with increasing Cr element. | Xiurong Guan Enze Liu Zhi Zheng Yongsi Yu Jian Tong Yuchun Zhai | 2011 | Journal of Materials Science & Technology2011，27，2： | 9 |
| 5 | Microbiologically influenced corrosion of titanium caused by aerobic marine bacterium Pseudomonas aeruginosa显示文摘Microbiologically influenced corrosion(MIC) is a big threat to the strength and safety of many metallic materials used in different environments throughout the world. The metabolites and bioactivity of the microorganisms cause severe deterioration on the metals. In this study, MIC of pure titanium(Ti) was studied in the presence of a highly corrosive aerobic marine bacterium Pseudomonas aeruginosa. The results obtained from electrochemical test showed that Ti was corrosion resistant in the abiotic culture medium after 14 d, while the increased corrosion current density(i_(corr)) obtained from polarization curves and the decreased charge transfer resistance(R_(ct)) from electrochemical impedance spectroscopy(EIS)indicated the accelerated corrosion of Ti caused by P. aeruginosa biofilm. For further confirmation of the above results, the surface of Ti was investigated using scanning electron microscopy(SEM), confocal laser scanning microscopy(CLSM) and X-ray photoelectron spectroscopy(XPS). According to the XPS results, TiO_2 was formed in both abiotic and biotic conditions, while unstable oxide Ti_2O_3 was detected in the presence of P. aeruginosa, leading to the defects in the passive film and localized corrosion. Pitting corrosion was investigated with the help of CLSM, and the largest pit depth found on Ti surface immersed in P. aeruginosa was 1.2 μm. Ti was not immune to MIC caused by P. aeruginosa. | M.Saleem Khan Zhong Li Ke Yang Dake Xu Chunguang Yang Dan Liu Yassir Lekbach Enze Zhou Phuri Kalnaowakul | 2019 | Journal of Materials Science & Technology2019，35，1： | 8 |
| 6 | A novel Cu-bearing high-entropy alloy with significant antibacterial behavior against corrosive marine biofilms显示文摘The design of novel high-entropy alloys(HEAs)provides a unique opportunity for the development of structure-function integrated materials with high mechanical and antimicrobial properties.In this study,by employing the antibacterial effect of copper,a novel Al0.4CoCrCuFeNi HEA with broad-spectrum antibacterial and strong mechanical properties was designed.High concentrations of copper ions released from the HEA prevented growth and biofilm formation by biocorrosive marine bacterial species.These findings serve as a proof-of-concept for further development of unique HEA materials with high antimicrobial efficiency and mechanical properties,compared to conventional antibacterial alloys. | Enze Zhou Dongxu Qiao Yi Yang Dake Xu Yiping Lu Jianjun Wang Jessica A.Smith Huabing Li Hongliang Zhao Peter K.Liaw Fuhui Wang | 2020 | Journal of Materials Science & Technology2020，42，11： | 6 |
| 7 | A Comparative Study of Methods for Delineating Sphere of Urban Influence: A Case Study on Central China显示文摘A number of urban and regional plans have been developed with the advancement of urbanization and regional integration, among which the delineation of sphere of urban influence and improvement of integration between the city and its hinterland have become vital important for guiding practices. In terms of delineating sphere of urban influence, existing studies have been focused on static study by using single year data or single method, resulting in a lack of time-series longitudinal analysis or comprehensive analysis based on multiple methods. This study emphasizes on comparing two methods from both the theoretical and empirical perspective. Both gravity model and improved field model are applied to the selected study area for measurements and comparison, to explore their strengths and weaknesses. A research framework for comprehensive analysis on delineating sphere of urban influence is proposed. In the end, the differences of delineating methods are illustrated and the feasibility of comprehensive analysis is discussed. Recommendations are provided for selecting appropriate methods for delineating sphere of urban influence or developing regional hierarchy system plans and urban spatial structure schemes. | WANG Hao DENG Yu TIAN Enze WANG Kaiyong | 2014 | Chinese Geographical Science2014，24，6： | 6 |
| 8 | Methanogenic archaea and sulfate reducing bacteria induce severe corrosion of steel pipelines after hydrostatic testing显示文摘Complex interactions within a microbial consortium can induce severe corrosion in oil pipelines.This study investigated the mechanism of microbiologically influenced corrosion(MIC)that led to failure of X52 steel pipelines after hydrostatic testing.Laboratory hydrostatic testing with untreated lake water and underground water were used to simulate and study the events that led to the actual corrosion.Biofilm analysis,weight loss,and several electrochemical measurements demonstrated rapid corrosion rates after hydrostatic testing.Analysis of microbial community structures revealed that methanogenic archaea and sulfate reducing bacteria(SRB),introduced by the hydrotest water,formed corrosive biofilms on X52 steel coupon surfaces that induced severe pitting. | Enze Zhou Jianjun Wang Masoumeh Moradi Huabing Li Dake Xu Yuntian Lou Jinheng Luo Lifeng Li Yulei Wang Zhenguo Yang Fuhui Wang Jessica A.Smith | 2020 | Journal of Materials Science & Technology2020，47，13： | 5 |
| 9 | Influence of Ru on Solidification Behavior, Microstructure and Hardness of Re-free Ni-based Equiaxed Superalloys with High Cr Content显示文摘The effect of Ru addition on solidification behavior, microstructure and hardness of Re-free Ni-based equiaxed superalloys with high Cr content has been investigated. With the increase of Ru, the solidus temperature of the alloys and the γ′ solvus temperature decreased, respectively. However, the liquidus temperatures of the alloys had no obvious change. The microstructure of the as-cast alloys was mainly composed of γ, γ′, γ/γ′ eutectic and MC carbides. The γ/γ′ eutectic was completely dissolved after the heat treatment. The morphology of γ′ was more cuboidal in heat-treated alloys with increasing Ru. Furthermore, the volume fraction of γ′ in the as-cast and heat-treated alloys diminished upon the increase of Ru. It was noted that Ru addition changed the segregation behaviors of Cr and Mo in the alloys from positive segregation element to negative segregation element and promotes the segregation degree of W.As the Ru content increased, the magnitude of segregation of the positive segregation elements Ta and Ti increased accordingly. Meanwhile, the magnitude of Al segregation decreased and Ru tended to segregate in the dendrite core. In addition, the hardness of the alloys improved and their porosity reduced with increasing amount of Ru. | Yingshuang Guan Enze Liu Xiurong Guan Zhi Zheng | 2016 | Journal of Materials Science & Technology2016，32，3： | 5 |
| 10 | Influence of Pre-oxidation on the Hot Corrosion of DZ68 Superalloy in the Mixture of Na_2SO_4-NaCl显示文摘DZ68 alloy is a new Ni-base directionally solidified superalloy for the blade of advanced turbine engine with high ratio of thrust-mass.In order to investigate the influence of pre-oxidation on the hot corrosion resistance of DZ68 alloy,pre-oxidation treatment was conducted at 950℃ in air for 20 h.A mixture of 75% Na2SO4 +25% NaCl (in mass fraction) was used for hot corrosion study at 900℃.The microstructure of specimens was investigated by using a scanning electron microscope (SEM) equipped with an energy dispersive spectroscopy (EDS).The compositions of the corroded specimens were determined by X-ray diffraction (XRD).After preoxidation at 950℃ in air for 20 h,a protective scale consisting of Cr2O3,Al2O3,NiO,NiCr2O4,and Ni2Ti4O formed on the DZ68 superalloy surface.The pre-oxidation treatment improved the initial incubation stage of the alloy in the mixture of 75% Na2SO4 +25% NaCl melts at 900℃.The oxide layer degraded gradually with increasing the time of hot corrosion.Once the oxide layer was damaged,the corrosion rate would increase rapidly,accompanied by obvious spallation of the corrosion products.At 900℃,the pre-oxidation treatment could not inhibit the accelerated hot corrosion of DZ68 in the mixture of 75% Na2SO4 +25% NaCl melts,with a high corrosion rate. | Enze Liu Zhi Zheng Xiurong Cuan Jian Tong Likui Ning Yongsi Yu | 2010 | Journal of Materials Science & Technology2010，26，10： | 4 |
| 11 | Enhanced resistance of 2205 Cu-bearing duplex stainless steel towards microbiologically influenced corrosion by marine aerobic Pseudomonas aeruginosa biofilms显示文摘An antibacterial 2205-Cu duplex stainless steel(DSS)was shown to inhibit the formation and growth of corrosive marine biofilms by direct contact with copper-rich phases and the release of Cu^(2+)ions from the2205-Cu DSS surface.In this work,the microbiologically influenced corrosion(MIC)resistance of 2205-Cu DSS in the presence of the corrosive marine bacterium Pseudomonas aeruginosa was investigated.The addition of copper improved the mechanical properties such as the yield strength,the tensile strength and the hardness of 2205 DSS.Electrochemical test results from linear polarization resistance(LPR),electrochemical impedance spectroscopy(EIS)and critical pitting temperature(CPT)measurements showed that 2205-Cu DSS possessed a larger polarization resistance(R_p),charge transfer resistance(R_(ct))and CPT values,indicating the excellent MIC resistance of 2205-Cu DSS against the corrosive P.aeruginosa biofilm.The live/dead staining results and the SEM images of biofilm confirmed the strong antibacterial ability of 2205-Cu DSS.The largest pit depth of 2205-Cu DSS was considerably smaller than that of 2205 DSS after 14 d in the presence of P.aeruginosa(2.2μm vs 12.5μm).2205-Cu DSS possessed a superior MIC resistance to regular 2205 DSS in the presence of aerobic P.aeruginosa. | Dake Xu Enze Zhou Ying Zhao Huabing Li Zhiyong Liu Dawei Zhang Chunguang Yang Hai Lin Xiaogang Li Ke Yang | 2018 | Journal of Materials Science & Technology2018，34，8： | 4 |

| 13 | Magnetically stabilized bed reactor for selective hydrogenation of olefins in reformate with amorphous nickel alloy catalyst显示文摘A magnetically stabilized bed (MSB) reactor for selective hydrogenation of olefins in reformate was developed by combining the advantages of MSB and amorphous nickel alloy catalyst. The effects of operating conditions, such as temperature, pressure, liquid space velocity, hydrogen-to-oil ratio, and magnetic field intensity on the reaction were studied. A mathematical model of MSB reactor for hydrogenation of olefins in reformate was established. A reforming flow scheme with a post-hydrogenation MSB reactor was proposed. Finally, MSB hydrogenation was compared with clay treatment and conventional post-hydrogenation. | Xuhong Mu Enze Min | 2007 | China Particuology2007，5，1： | 3 |
| 14 | Microstructural Evolution of a Ni-base Alloy DZ468 Joint Bonded with a New Co-base Filler显示文摘Ni-base alloy DZ468 has been joined by transient liquid phase bonding technique with a newly developed Co-based filler.The microstructures of the Co-base filler and the joint,the effects of heat treatment on microstructure and hardness of the joint have been investigated by various experimental methods.Results show that the Co-base filler consists ofγ,M_2B,M_5B_3 and M_(23)B_6 phases.Because of the interdiffusion between the base metal and the filler,y,MC,M_5B_3 and M_(23)B_6 phases are formed in the bonding zone.And localized liquidation of substrate occurs in the diffusion affected zone,with MC and M_3B_2 precipitating in this area.During heat treatment,the volume of the intermetallic phases in the bonding zone resulting from incomplete isothermal solidification decreases obviously.On the contrary,the width of the diffusion affected zone increases at the solution stage and subsequently decreases at the aging stages. | Yanhong Jing Zhi Zheng Enze Liu Yi Guo | 2014 | Journal of Materials Science & Technology2014，30，5： | 3 |

| 16 | An Inactivated Vaccine from a Field Strain of Bovine Herpesvirus-1(BoHV-1) has High Antigenic Mass and Induces Strong Efficacy in a Rabbit Model显示文摘Bovine Herpesvirus-1 (BoHV-1) is a DNA virus belonging to the family Herpesviridae, subfamily Alfaherpesvirinae; it is a worldwide pathogen, causing serious economic losses in livestock. In Colombia there have been multiple isolates of BoHV-1 that have been subjected to molecular characterization, classifying most of the country isolates as BoHV-1.1. In the present study we developed and evaluated an ethyleneimine binary inactivated isolate from the native BoHV-1 strain (Córdoba-2) in a rabbit model of vaccination and infection. The vaccine was evaluated in two phases, one of immunogenicity with vaccination and a booster after 21 days, and an evaluation phase of protection against challenge with a highly virulent reference strain. The results demonstrate optimum serum-conversion, with protective neutralizing antibody titers 28 days post vaccination and optimal protection against challenge with the reference strain with decreased clinical signs of infection, protection against the onset of fever and decrease of virus excretion post challenge. In conclusion, our results show the enormous potential that an immunogenic inactivated vaccine has produced from the native BoHV-1.1 strain, which produces a high antigen mass to the vaccine to induce optimal immunity and protection, and it is a strong candidate for evaluation and possible future use in different cattle populations. | Julian Ruiz-Sáenz Jairo Jaime Victor Vera | 2013 | Virologica Sinica2013，28，1： | 2 |
| 17 | Properties of a water layer on hydrophilic and hydrophobic self-assembled monolayer surfaces: A molecular dynamics study显示文摘The microscopic behaviors of a water layer on different hydrophilic and hydrophobic surfaces of well ordered self-assembled monolayers (SAMs) are studied by molecular dynamics simulations. The SAMs consist of 18-carbon alkyl chains bound to a silicon(111) substrate, and the characteristic of its surface is tuned from hydrophobic to hydrophilic by using different terminal functional groups ( CH 3 , COOH). In the simulation, the properties of water membranes adjacent to the surfaces of SAMs were reported by comparing pure water in mobility, structure, and orientational ordering of water molecules. The results suggest that the mobility of water molecules adjacent to hydrophilic surface becomes weaker and the molecules have a better ordering. The distribution of hydrogen bonds indicates that the number of water-water hydrogen bonds per water molecule tends to be lower. However, the mobility of water molecules and distribution of hydrogen bonds of a water membrane in hydropho- bic system are nearly the same as those in pure water system. In addition, hydrogen bonds are mainly formed between the hydroxyl of the COOH group and water molecules in a hydrophilic system, which is helpful in understanding the structure of interfacial water. | LI EnZe DU ZhiPing YUAN ShiLing | 2013 | Science China Chemistry2013，56，6： | 2 |
| 18 | Edge superconductivity in multilayer WTe2 Josephson junction显示文摘WTe2,as a type-ⅡWeyl semimetal,has 2D Fermi arcs on the(O01)surface in the bulk and 1D helical edge states in its monolayer.These features have recently attracted wide attention in condensed matter physics.However,in the intermediate regime between the bulk and monolayer,the edge states have not been resolved owing to its closed band gap which makes the bulk states dominant.Here,we report the signatures of the edge superconductivity by superconducting quantum interference measurements in multilayerWTe2 Josephson junctions and we directly map the localized supercurrent.In thickWTe(~60nm),the supercurrent is uniformly distributed by bulk states with symmetricJosephson effect(|Ic+(B)|=|Ic^-(B)|).In thin WTe2(10 nm),however,the supercurrent becomes confined to the edge and its width reaches up to 1.4μm and exhibits non-symmetric behavior|Ic^+(B)|≠|Ic^-(B)|.The ability to tune the edge domination by changing thickness and the edge superconductivity establishes WTez as a promising topological system with exotic quantum phases and a rich physics. | Ce Huang Awadhesh Narayan Enze Zhang Xiaoyi Xie Linfeng Ai Shanshan Liu Changjiang Yi Youguo Shi Stefano Sanvito Faxian Xiu | 2020 | National Science Review2020，7，9： | 2 |
