| 1 | Efficient Attribute-Based Encryption from R-LWE显示文摘Attribute-based encryption(ABE) has been an active research area in cryptography due to its attractive applications. But almost all attribute-based encryption schemes are based on bilinear maps, which leave them vulnerable to quantum cryptanalysis. The latticebased ABE schemes from the Learning with errors(LWE)have appeared, but they are not efficient enough for practical applications. Thus we propose an efficient attributebased encryption based on the Learning with errors over Rings(R-LWE), which is called ABE R-LWE. The security analysis shows that ABE R-LWE scheme is secure in the selective-set model under the R-LWE assumption, whose security can reduce to the hardness of the shortest vector problem in the worst case on ideal lattices. The efficiency analysis indicates that ABE R-LWE is more efficient than previous ABE cryptosystems on lattices. | ZHU Weiling YU Jianping WANG Ting ZHANG Peng XIE Weixin | 2014 | Chinese Journal of Electronics2014，23，4： | 6 |
| 2 | Variation effect of strain rate on microstructure in isothermal compression of Ti-6Al-4V alloy显示文摘Isothermal compression of the Ti-6Al-4V alloy at the deformation temperatures of 950 and 980℃,height reductions of 30% and 60%,and strain rates of 0.001,0.010,0.100 and 1.000 s-1 was conducted,wherein the variations of microstructure with strain rate were investigated.The experimental results showed that the variation of the microstructure with the strain rate under one condition was significantly different from that under another condition,which meaned that the interaction between the processing parameters was great.The optimization of the strain rate under one condition was not suitable for another condition.Therefore,selecting the forging equipment and optimizing the strain rate should be based on simultaneously considering the deformation temperature and height reduction. | Yu, Weixin Li, Miaoquan Luo, Jiao | 2012 | Rare Metals2012，31，1： | 6 |
| 3 | Modeling of void closure in diffusion bonding process based on dynamic conditions显示文摘The dynamic conditions for plastic deformation mechanism,surface source mechanism,interface source mechanism and creep mechanism in the diffusion bonding process are proposed.Based on these dynamic conditions,a model for void closure in the diffusion bonding process is derived.The effects of diffusion bonding parameters on the bonding mechanisms are analyzed.For the diffusion bonding process of TC4 alloy,at a low diffusion bonding temperature or pressure,or for a short time,the interface source mechanism plays a main role.But,the creep mechanism is the dominant mechanism and operates until the diffusion bonding is fulfilled.As the diffusion bonding time increases,the surface source and interface source mechanism enhance and then stop at a certain stage of diffusion bonding,while the creep mechanism enhances continuously.As the diffusion bonding temperature or pressure increases,the interface source mechanism weakens and the other mechanisms enhance.The maximum and average errors between the calculated and the experimental results in the diffusion bonding for TC4 alloy are 12.86% and 5.79%,respectively. | MA RuiFang LI MiaoQuan LI Hong YU WeiXin | 2012 | Science China(Technological Sciences)2012，55，9： | 5 |
| 4 | HIV Prevention and Health Poverty Alleviation-Liangshan Prefecture,Sichuan Province,China,2017-2020显示文摘BACKGROUND Liangshan,officially the Liangshan Yi Autonomous Prefecture,is an autonomous prefecture occupying much of the southern portion of Sichuan Province.It has been a remote and deeply impoverished area and also has the largest population of ethnic Yi people in China(1).For many years,due to geographical environment conditions,traffic conditions,and other historic restrictions,the human immunodeficiency virus(HIV)epidemic in Liangshan Prefecture has become the focus of HIV prevention and control in China since the first acquired immunodeficiency syndrome(AIDS)case was reported in this area in 1995(2-3). | Zhongfu Liu Xuefeng Tang Yufen Liu Linglin Zhang Yihui Yang Yongli Zheng Weixin Liu Chunnong Jike Hong Mai Heying Fan Gang Yu Mengjie Han George F.Gao | 2021 | China CDC weekly2021，3，48： | 4 |

| 6 | Robust adaptive control of hypersonic flight vehicle with asymmetric AOA constraint显示文摘This paper investigates the state-constrained controller design of a hypersonic flight vehicle(HFV)based on an asymmetric barrier Lyapunov function(ABLF).The robust adaptive back-stepping controller with integral terms is applied for the HFV longitudinal dynamics.Considering the asymmetric angle of attack(AOA)constraint caused by the unique structure and scramjet,the controller is modified by constructing an ABLF,where the asymmetric constraint on AOA tracking error is introduced.Combined with the constraint on virtual control,the AOA is restricted to a predefined asymmetric interval.The system stability and the AOA constraint are guaranteed via Lyapunov analysis.Simulation results verify that the AOA can be kept in the given asymmetric interval while the altitude reference signal is tracked. | Yuyan GUO Bin XU Weixin HAN Shuai LI Yueping WANG Yu ZHANG | 2020 | Science China(Information Sciences)2020，63，11： | 4 |
| 7 | Thermo-Hydraulic Characteristics of Non-Isothermal Batch Transportation Pipeline System with Different Inlet Oil Temperature显示文摘The batch transportation process of several kinds of crude oil is accomplished by an entire coupled pipeline system,which exhibits complex thermo-hydraulic characteristics.Based on the coupled characteristics among soil,pipelines and devices(including pumps,heating furnaces and valves),a coupled simulation model of batch transportation for the crude oil pipeline system is established,and a novel coupled simulation algorithm is proposed.The simulation results are in good agreement with the field data of an actual crude oil pipeline system.In addition,based on the numerical simulation,thermo-hydraulic characteristics of pipeline system are investigated,and some new thermo-hydraulic characteristics are obtained.In the batch transportation process with constant flowrate,the change trends of temperature at the outlet of each pipeline segment are hysteretic and the change ranges of temperature become small along mileage.And the adjustment of devices influences thermohydraulic characteristics to some extent.In the batch transportation process with variable flowrate,the complex thermo-hydraulic characteristics are exhibited,which are induced by the comprehensive influence of the changes of oil type,flowrate and absorbed/released heat.Compared with the transportation process with constant flowrate,the high-viscosity oil exhibits similar minimum temperature and lower maximum pressure in the transportation process with variable flowrate,which means that the higher transportation safety of pipeline system is obtained.This study can provide a scientific reference for making the safer batch transportation scheme of crude oil pipeline system. | CHEN Zhimin YUAN Qing JIANG Weixin LI Zongze YU Bo | 2023 | Journal of Thermal Science2023，32，3： | 2 |
