| 1 | Development of an Intelligent Vehicle Experiment System显示文摘Existing vehicle experiment systems tend to focus on the research of vehicle dynamics by conducting performance tests on every system or some parts of the vehicle so as to improve the entire performance of the vehicle.Virtual technology is widely utilized in various vehicle test-beds.These test-beds are mainly used to simulate the driving training,conduct the research on drivers' behaviors,or give virtual demonstrations of the transportation environment.However,the study on the active safety of the running vehicle in the virtual environment is still insufficient.A virtual scene including roads and vehicles is developed by using the software Creator and Vega,and radars and cameras are also simulated in the scene.Based on dSPACE's rapid prototyping simulation and its single board DS1103,a simulation model including vehicle control signals is set up in MATLAB/Simulink,the model is then built into C code,and the system defined file(SDF) is downloaded to the DS1103 board through the experiment debug software ControlDesk and is kept running.Programming is made by mixing Visual C++ 6.0,MATLAB API and Vega API.Control signals are read out by invoking library function MLIB/MTRACE of dSPACE.All the input,output,and system state values are acquired by arithmetic and are dynamically associated with the running status of the virtual vehicle.An intelligent vehicle experiment system is thus developed by virtue of program and integration.The system has not only the demonstration function,such as general driving,cruise control,active avoiding collision,but also the function of virtual experiment.Parameters of the system can be set according to needs,and the virtual test results can be analyzed and studied and used for the comparison with the existing models.The system reflects the running of the intelligent vehicle in the virtual traffic environment,at the same time,the system is a new attempt performed on the intelligent vehicle travel research and provides also a new research method for the development of intelligent vehicles. | YANG Xinhong GAO Feng LIU Guoliang WANG Guofu XU Guoyan | 2010 | Chinese Journal of Mechanical Engineering2010，23，6： | 5 |
| 2 | Dynamic Modeling and Analysis of 9-DOF Omnidirectional Legged Vehicle显示文摘The omnidirectional legged vehicle with steering-rails has a specific mechanism feature, and it can be controlled flexibly and accurately in omnidirectional motion. Currently there lacks further research in this area. In this paper, the mechanical characteristics of independent walking control and steering control and its kinematics principle are introduced, and a vehicle has a composite motion mode of parallel link mechanism and steering mechanism is presented. The motion direction control of the proposed vehicle is only dependant on its steering rails, so its motion is simple and effective to control. When the relative motion between the walking and steering is controlled cooperatively, the vehicle can walk perfectly. By controlling the steering rails, the vehicle can walk along arbitrary trajectory on the ground. To achieve a good result of motion control, an equivalent manipulator model needs to be built. In terms of the mechanism feature and the kinematic principle, the simplified manipulator model consists of a rail in stance phase, a rail in swing phase, and an equivalent leg. Considering the ground surface slope during walking, a parameter of inclination angle is added. Based on such a RPP manipulator model, the equations of motion are derived by means of Lagrangian dynamic approach. To verify the dynamic equations, the motion of the manipulator model is simulated based on linear and nonlinear motion planning. With the same model and motion parameters, the dynamic equations can be solved by Matlab and the calculation data can be gained. Compared with the simulation data, the result confirms the manipulator dynamic equations are correct. As a result of such special characteristics of the legged mechanism with steering rails, it has a potential broad application prospects. The derivation of dynamics equation could benefit the motion control of the mechanism. | GAO Feng WANG Guofu CUI Ying YANG Xinhong | 2011 | Chinese Journal of Mechanical Engineering2011，24，4： | 3 |

| 6 | The optimization of replica distribution in the unstructured overlays显示文摘Replication is a widely used technique in unstructured overlays to improve content availability or system performance. A fundamental question often addressed by previous work focused on: how many replicas ought to be allocated for each data item given the fixed query rates and limited storage capability? In this paper, we have put forth two optimal replica distributions to achieve the highest success rate and the lowest message consumption. Especially, we have investigated the influence of item size on replica distribution. Our results show that Square-Root Replication, which is traditionally considered to be optimal, is not always the best choice. Our study offers a new deep understanding of resource managment in self-organized unstructured overlays. | FENG GuoFu LI WenZhong LU SangLu CHEN DaoXu BUYYA Rajkumar | 2012 | Science China(Information Sciences)2012，55，3： | 1 |

| 9 | Screening and identification of Shigella flexneri 2a virulence-related genes induced after invasion of epithelial cells显示文摘An in vivo expression technology (IVET) was applied to screen s.flexneri 2a genes induced after invasion of epithelial cells, and virulence-related genes were further identified by mutational analysis. Thirteen intracellular induced genes were identified with a HeLa cell infection model. Of these, two were identified as alkylation-related genes; one was related to metabolism; one encoded a transcriptional regulator; three were identified as insertion elements; three ap- peared to be antisense to genes involved in the transmethylation,biosyntheseis, and phos- photransferase system;and three were predicted to encode polypeptides with unknown functions. Intracellular survival assavs showed that the mutants of alkA,citC and wcaJ genes had lower capability of intracellular replication or survival than the the wild-type strain.The results indicated that alkA, citC and wcaJ genes could take part in the intracellular survival or replication of S. flexneri 2a and the capability of intracellular survival or replication could be one of the major virulence elements. However, the yaiC mutant was able to survive in the murine infection assay but almost not in HeLa cell infection assay. Very possibly, yaiC gene was involved in the other mechanism of S. flexneri virulence. This study might lead to a better understanding of the intra- cellular survival or proliferation process of S. flexneri 2a and perhaps provide insights into the pathogenicity of this pathogen. | SHI Zhaoxing WANG Hengliang HU Kun FENG Erling YAO Xiao HUANG Liuyu SU Guofu HUNAG Peitang HUANG Cuifen | 2004 | Science China(Life Sciences)2004，47，6： | 0 |
| 10 | A study of plasmon-driven catalytic 4-NBT to DMAB in the dry film by using spatial Raman mapping spectroscopy显示文摘Plasmon-driven catalytic reaction(PDCR)as a part of photocatalysis has attracted immense attention.Due to the collective oscillation of free electrons at the surface of metallic nanostructures,the charge distributions store energy from the incident light that could transfer energy to molecules that promote photocatalysis.As an environment-friendly and green photocatalysis process,PDCR illustrates a brilliant future.In this study,the PDCR efficiency of photo-reducing 4-nitro-benzenthiol(4-NBT)dry film to p,p'-dimercaptoazobenzene(DMAB)in ambient conditions has been studied by using Ag nanodiscs(NDs)and Ag nanoparticles(NPs)as catalysts.The distribution of catalytic efficiency of 4-NBT to DMAB using an individual Ag ND catalyst has been illustrated using spatial Raman mapping.The result is direct evidence that the PDCR efficiency has a positive correlation with plasmon-induced electromagnetic field intensity.Additionally,time-dependent surface-enhanced Raman scattering(SERS)experiments reveal that the PDCR of 4-NBT to DMAB is reciprocal.The discovery in this research will aid to improve the PDCR performance and modulate the catalysis reaction for a high reduction of 4-NBT in industrial. | Yansheng Liu Junpeng Deng Zhicheng Jin Tianxing Liu Jin Zhou Feng Luo Guofu Wang | 2022 | Nano Research2022，15，7： | 0 |
| 11 | A reflective display based on the electro-microfluidic assembly of particles within suppressed water-in-oil droplet array显示文摘Reflective displays have stimulated considerable interest because of their friendly readability and low energy consumption.Herein,we develop a reflective display technique via an electro-microfluidic assembly of particles(eMAP)strategy whereby colored particles assemble into annular and planar structures inside a dyed water droplet to create'open'and'closed'states of a display pixel.Water-in-oil droplets are compressed within microwells to form a pixel array.The particles dispersed in droplets are driven by deformation-strengthened dielectrophoretic force to achieve fast and reversible motion and assemble into multiple structures.This eMAP based device can display designed information in three primary colors with≥170°viewing angle,~0.14 s switching time,and bistability with an optimized material system.This proposed technique demonstrates the basis of a high-performance and energy-saving reflective display,and the display speed and color quality could be further improved by structure and material optimization;exhibiting a potential reflective display technology. | Shitao Shen Haoqiang Feng Yueming Deng Shuting Xie Zichuan Yi Mingliang Jin Guofu Zhou Paul Mulvaney Lingling Shui | 2023 | Light(Science & Applications)2023，12，12： | 0 |
| 12 | Feasibility and physics potential of detecting ^(8)B solar neutrinos at JUNO显示文摘The Jiangmen Underground Neutrino Observatory(JUNO)features a 20 kt multi-purpose underground liquid scintillator sphere as its main detector.Some of JUNO's features make it an excellent location for^8B solar neutrino measurements,such as its low-energy threshold,high energy resolution compared with water Cherenkov detectors,and much larger target mass compared with previous liquid scintillator detectors.In this paper,we present a comprehensive assessment of JUNO's potential for detecting^8B solar neutrinos via the neutrino-electron elastic scattering process.A reduced 2 MeV threshold for the recoil electron energy is found to be achievable,assuming that the intrinsic radioactive background^(238)U and^(232)Th in the liquid scintillator can be controlled to 10^(-17)g/g.With ten years of data acquisition,approximately 60,000 signal and 30,000 background events are expected.This large sample will enable an examination of the distortion of the recoil electron spectrum that is dominated by the neutrino flavor transformation in the dense solar matter,which will shed new light on the inconsistency between the measured electron spectra and the predictions of the standard three-flavor neutrino oscillation framework.IfDelta m^(2)_(21)=4.8times10^(-5);(7.5times10^(-5))eV^(2),JUNO can provide evidence of neutrino oscillation in the Earth at approximately the 3sigma(2sigma)level by measuring the non-zero signal rate variation with respect to the solar zenith angle.Moreover,JUNO can simultaneously measureDelta m^2_(21)using^8B solar neutrinos to a precision of 20% or better,depending on the central value,and to sub-percent precision using reactor antineutrinos.A comparison of these two measurements from the same detector will help understand the current mild inconsistency between the value of Delta m^2_(21)reported by solar neutrino experiments and the KamLAND experiment.

| 15 | A flexible and high temperature tolerant strain sensor of La0.7Sr0.3MnO3/Mica显示文摘Flexible sensors have been widely investigated due to their broad application prospects in various flexible electronics.However,most of the presently studied flexible sensors are only suitable for working at room temperature,and their applications at high or low temperatures are still a big challenge.In this work,we present a multimodal flexible sensor based on functional oxide La0.7Sr0.3MnO3(LSMO)thin film deposited on mica substrate.As a strain sensor,it shows excellent sensitivity to mechanical bending and high bending durability(up to 3600 cycles).Moreover,the LSMO/Mica sensor also shows a sensitive response to the magnetic field,implying its multimodal sensing ability.Most importantly,it can work in a wide temperature range from extreme low temperature down to 20K to high temperature up to 773 K.The flexible sensor based on the flexible LSMO/mica hetero-structure shows great potential applications for flexible electronics using at extreme temperature environment in the future. | Min Guo Cheng Yang Dong Gao Qiang Li Aihua Zhang Jiajun Feng Hui Yang Ruiqiang Tao Zhen Fan Min Zeng Guofu Zhou Xubing Lu J-MLiu | 2020 | Journal of Materials Science & Technology2020，44，9： | 0 |

| 17 | Subdivision for Generating Quadrics显示文摘Quadrics are of basic importance in Computer Graphics and Computer Aided Design. In this paper,we design a subdivision scheme based on the method suggested by G. Morin and J. Warren to generate conics and quadrics conveniently. Given the control polygon(poly-hedron),the corresponding ellipse (ellipsoid)can be generated. The hyperbolas and hyperboloids are generated based on the generation of ellipses and ellipsoids by a simple transformation. The method in this paper is much simpler and easier to apply than those given by Eugenia Montiel et al. | Wei Guofu Feng Yuyu Chen Falai | 2002 | 计算机科学2002，29，z2： | 0 |
