| 1 | Four Wheel Independent Drive Electric Vehicle Lateral Stability Control Strategy显示文摘In this paper,a kind of lateral stability control strategy is put forward about the four wheel independent drive electric vehicle.The design of control system adopts hierarchical structure.Unlike the previous control strategy,this paper introduces a method which is the combination of sliding mode control and optimal allocation algorithm.According to the driver’s operation commands(steering angle and speed),the steady state responses of the sideslip angle and yaw rate are obtained.Based on this,the reference model is built.Upper controller adopts the sliding mode control principle to obtain the desired yawing moment demand.Lower controller is designed to satisfy the desired yawing moment demand by optimal allocation of the tire longitudinal forces.Firstly,the optimization goal is built to minimize the actuator cost.Secondly,the weighted least-square method is used to design the tire longitudinal forces optimization distribution strategy under the constraint conditions of actuator and the friction oval.Beyond that,when the optimal allocation algorithm is not applied,a method of axial load ratio distribution is adopted.Finally,Car Sim associated with Simulink simulation experiments are designed under the conditions of different velocities and different pavements.The simulation results show that the control strategy designed in this paper has a good following effect comparing with the reference model and the sideslip angle is controlled within a small rang at the same time.Beyond that,based on the optimal distribution mode,the electromagnetic torque phase of each wheel can follow the trend of the vertical force of the tire,which shows the effectiveness of the optimal distribution algorithm. | Yantao Tian Xuanhao Cao Xiaoyu Wang Yanbo Zhao | 2020 | IEEE/CAA Journal of Automatica Sinica2020，7，6： | 7 |
| 2 | The Indirect Shared Steering Control Under Double Loop Structure of Driver and Automation显示文摘Due to the critical defects of techniques in fully autonomous vehicles,man-machine cooperative driving is still of great significance in today’s transportation system.Unlike the previous shared control structure,this paper introduces a double loop structure which is applied to indirect shared steering control between driver and automation.In contrast to the tandem indirect shared control,the parallel indirect shared control put the authority allocation system of steering angle into the framework to allocate the corresponding weighting coefficients reasonably and output the final desired steering angle according to the current deviation of vehicle and the accuracy of steering angles.Besides,the active disturbance rejection controller(ADRC)is also added in the frame in order to track the desired steering angle fleetly and accurately as well as restrain the internal and external disturbances effectively which including the steering friction torque,wind speed and ground interference etc.Eventually,we validated the advantages of double loop framework through three sets of double lane change and slalom experiments,respectively.Exactly as we expected,the simulation results show that the double loop structure can effectively reduce the lateral displacement error caused by the driver or the controller,significantly improve the tracking precision and keep great performance in trajectory tracking characteristics when driving errors occur in one of driver and controller. | Yantao Tian Yanbo Zhao Yiran Shi Xuanhao Cao Ding-Li Yu | 2020 | IEEE/CAA Journal of Automatica Sinica2020，7，5： | 6 |
| 3 | Dust removal efficiency of high pressure atomization in underground coal mine显示文摘To master theoretical calculation for dust removal efficiency of high pressure atomization in an underground coal mine, the corresponding atomization characteristics and dust removal efficiency were both comprehensively studied in theory by virtue of related theories of hydromechanics and aerosol.According to actual measurements of flow coefficients and atomization angles of X-type swirl nozzle,computational formula was derived for atomized particle sizes of such a nozzle in conjunction with relevant empirical equation. Moreover, a mathematical model for applying high pressure atomization to dust removal in underground coal mine was also established to deduce theoretical computation formula of fractional efficiency. Then, Matlab was adopted to portray the relation curve between fractional efficiency and influence factors. In addition, a theoretical formula was also set up for removal efficiency of respirable dust and total coal dust based on dust size and frequency distribution equations. In the end,impacts of dust characteristic parameters on various dust removal efficiencies were analyzed. | Pengfei Wang Xuanhao Tan Weimin Cheng Gang Guo Ronghua Liu | 2018 | International Journal of Mining Science and Technology2018，28，4： | 5 |
| 4 | Photonic devices based on thin-film lithium niobate on insulator显示文摘Lithium niobate on insulator(LNOI)is rising as one of the most promising platforms for integrated photonics due to the high-index-contrast and excellent material properties of lithium niobate,such as wideband transparency from visible to mid-infrared,large electro-optic,piezoelectric,and second-order harmonic coefficients.The fast-developing micro-and nanostructuring techniques on LNOI have enabled various structure,devices,systems,and applications.In this contribution,we review the latest developments in this platform,including ultra-high speed electro-optic modulators,optical frequency combs,opto-electro-mechanical system on chip,second-harmonic generation in periodically poled LN waveguides,and efficient edge coupling for LNOI. | Shuai Yuan Changran Hu An Pan Yuedi Ding Xuanhao Wang Zhicheng Qu Junjie Wei Yuheng Liu Cheng Zeng† Jinsong Xia | 2021 | Journal of Semiconductors2021，42，4： | 2 |
| 5 | Underwater Terrain Image Stitching Based on Spatial Gradient Feature Block显示文摘At present,underwater terrain images are all strip-shaped small fragment images preprocessed by the side-scan sonar imaging system.However,the processed underwater terrain images have inconspicuous and few feature points.In order to better realize the stitching of underwater terrain images and solve the problems of slow traditional image stitching speed,we proposed an improved algorithm for underwater terrain image stitching based on spatial gradient feature block.First,the spatial gradient fuzzy C-Means algorithm is used to divide the underwater terrain image into feature blocks with the fusion of spatial gradient information.The accelerated-KAZE(AKAZE)algorithm is used to combine the feature block information to match the reference image and the target image.Then,the random sample consensus(RANSAC)is applied to optimize the matching results.Finally,image fusion is performed with the global homography and the optimal seam-line method to improve the accuracy of image overlay fusion.The experimental results show that the proposed method in this paper effectively divides images into feature blocks by combining spatial information and gradient information,which not only solves the problem of stitching failure of underwater terrain images due to unobvious features,and further reduces the sensitivity to noise,but also effectively reduces the iterative calculation in the feature point matching process of the traditional method,and improves the stitching speed.Ghosting and shape warping are significantly eliminated by re-optimizing the overlap of the image. | Zhenzhou Wang Jiashuo Li Xiang Wang Xuanhao Niu | 2022 | Computers, Materials & Continua2022，，8： | 1 |

| 12 | Prudent application of single-cell RNA sequencing in understanding cellular features and functional phenotypes in cancer studies显示文摘This decade has seen remarkable advances in the field of high-throughput single cell techniques.Single-cell RNA sequencing(sc RNA-seq)has proven to be a powerful strategy to study the heterogeneity in clinical samples,providing an unbiased approach to uncover the characteristics in different cell subsets.To ensure the reproducibility and robustness of biological discoveries,researchers need to be aware of hidden caveats in tissue dissociation,cell capturing and transcripts measurement which may affect cell composition assessment and cellular function annotation.With measured interpretation of data and innovations in experimental and technical approaches,sc RNA-seq can greatly unravel the heterogeneity in complex system and improve our understandings in tissue homeostasis and cancer biology. | Xuanhao Xu Zemin Zhang | 2021 | Chinese Journal of Cancer Research2021，33，6： | 1 |
| 13 | A 0.5-meter-scale,high-load,soft-enclosed gripper capable of grasping the human body显示文摘Developing large,soft grippers with high omnidirectional load(above 40 kg)has always been challenging.We address this challenge by developing a powerful soft gripper that can grasp the human body based on a soft-enclosed grasping structure and a soft-rigid coupling structure.The envelope size of the proposed soft gripper is 611.6 mm×559 mm×490.7 mm,the maximum grasping size is 417 mm,and the payload on the human body is more than 90 kg,which has exceeded most existing soft grippers.Furthermore,the grasping force prediction of the gripper is achieved through theoretical modeling.The primary contribution of this work is to overcome the size and payload limits of current soft grippers and implement a human-grasping experiment based on the soft-grasping method. | LI HaiLi ZHANG Shuai ZHANG XuanHao ZHAO WuMian YAO JianTao | 2023 | Science China(Technological Sciences)2023，66，2： | 0 |
| 14 | An energy consumption prediction approach of die casting machines driven by product parameters显示文摘Die casting machines,which are the core equipment of the machinery manufacturing industry,consume great amounts of energy.The energy consumption prediction of die casting machines can support energy consumption quota,process parameter energy-saving optimization,energy-saving design,and energy efficiency evaluation;thus,it is of great significance for Industry 4.0 and green manufacturing.Nevertheless,due to the uncertainty and complexity of the energy consumption in die casting machines,there is still a lack of an approach for energy consumption prediction that can provide support for process parameter optimization and product design taking energy efficiency into consideration.To fill this gap,this paper proposes an energy consumption prediction approach for die casting machines driven by product parameters.Firstly,the system boundary of energy consumption prediction is defined,and subsequently,based on the energy consumption characteristics analysis,a theoretical energy consumption model is established.Consequently,a systematic energy consumption prediction approach for die casting machines,involving product,die,equipment,and process parameters,is proposed.Finally,the feasibility and reliability of the proposed energy consumption prediction approach are verified with the help of three die casting machines and six types of products.The results show that the prediction accuracy of production time and energy consumption reached 91.64%and 85.55%,respectively.Overall,the proposed approach can be used for the energy consumption prediction of different die casting machines with different products. | Erheng CHEN Hongcheng LI Huajun CAO Xuanhao WEN | 2021 | Frontiers of Mechanical Engineering2021，16，4： | 0 |

| 16 | A Review on Electrospinning as Versatile Supports for Diverse Nanofibers and Their Applications in Environmental Sensing显示文摘Rapid industrialization is accompanied by the deterioration of the natural environment.The deepening crisis associated with the ecological environment has garnered widespread attention toward strengthening environmental monitoring and protection.Environmental sensors are one of the key technologies for environmental monitoring,ultimately enabling environmental protection.In recent decades,micro/nanomaterials have been widely studied and applied in environmental sensing owing to their unique dimensional properties.Electrospinning has been developed and adopted as a facile,quick,and effective technology to produce continuous micro-and nanofiber materials.The technology has advanced rapidly and become one of the hotspots in the field of nanomaterials research.Environmental sensors made from electrospun nanofibers possess many advantages,such as having a porous structure and high specific surface area,which effectively improve their performance in environmental sensing.Furthermore,by introducing functional nanomaterials(carbon nanotubes,metal oxides,conjugated polymers,etc.)into electrospun fibers,synergistic effects between different materials can be utilized to improve the catalytic activity and sensitivity of the sensors.In this review,we aimed to outline the progress of research over the past decade on electrospinning nanofibers with different morphologies and functional characteristics in environmental sensors. | Jialing Song Xuanhao Lin Liang Ying Ee Sam Fong Yau Li Manhong Huang | 2023 | Advanced Fiber Materials2023，5，2： | 0 |
| 17 | Comparison of the Minimum Bounding Rectangle and Minimum Circumscribed Ellipse of Rain Cells from TRMM显示文摘Based on the TRMM dataset, this paper compares the applicability of the improved MCE(minimum circumscribed ellipse), MBR(minimum bounding rectangle), and DIA(direct indexing area) methods for rain cell fitting. These three methods can reflect the geometric characteristics of clouds and apply geometric parameters to estimate the real dimensions of rain cells. The MCE method shows a major advantage in identifying the circumference of rain cells. The circumference of rain cells identified by MCE in most samples is smaller than that identified by DIA and MBR, and more similar to the observed rain cells. The area of rain cells identified by MBR is relatively robust. For rain cells composed of many pixels(N> 20), the overall performance is better than that of MCE, but the contribution of MBR to the best identification results,which have the shortest circumference and the smallest area, is less than that of MCE. The DIA method is best suited to small rain cells with a circumference of less than 100 km and an area of less than 120 km^(2), but the overall performance is mediocre. The MCE method tends to achieve the highest success at any angle, whereas there are fewer “best identification”results from DIA or MBR and more of the worst ones in the along-track direction and cross-track direction. Through this comprehensive comparison, we conclude that MCE can obtain the best fitting results with the shortest circumference and the smallest area on behalf of the high filling effect for all sizes of rain cells. | Hongke CAI Yaqin MAO Xuanhao ZHU Yunfei FU Renjun ZHOU | 2024 | Advances in Atmospheric Sciences2024，41，3： | 0 |

| 19 | AIFM1 variants associated with auditory neuropathy spectrum disorder cause apoptosis due to impaired apoptosis-inducing factor dimerization显示文摘Auditory neuropathy spectrum disorder(ANSD)represents a variety of sensorineural deafness conditions characterized by abnormal inner hair cells and/or auditory nerve function,but with the preservation of outer hair cell function.ANSD represents up to 15%of individuals with hearing impairments.Through mutation screening,bioinformatic analysis and expression studies,we have previously identified several apoptosis-inducing factor(AIF)mitochondria-associated 1(AIFM1)variants in ANSD families and in some other sporadic cases.Here,to elucidate the pathogenic mechanisms underlying each AIFM1 variant,we generated AIF-null cells using the clustered regularly interspersed short palindromic repeats(CRISPR)/CRISPR-associated protein 9(Cas9)system and constructed AIF-wild type(WT)and AIF-mutant(mut)(p.T260A,p.R422W,and p.R451Q)stable transfection cell lines.We then analyzed AIF structure,coenzyme-binding affinity,apoptosis,and other aspects.Results revealed that these variants resulted in impaired dimerization,compromising AIF function.The reduction reaction of AIF variants had proceeded slower than that of AIF-WT.The average levels of AIF dimerization in AIF variant cells were only 34.5%-49.7%of that of AIF-WT cells,resulting in caspase-independent apoptosis.The average percentage of apoptotic cells in the variants was 12.3%-17.9%,which was significantly higher than that(6.9%-7.4%)in controls.However,nicotinamide adenine dinucleotide(NADH)treatment promoted the reduction of apoptosis by rescuing AIF dimerization in AIF variant cells.Our findings show that the impairment of AIF dimerization by AIFM1 variants causes apoptosis contributing to ANSD,and introduce NADH as a potential drug for ANSD treatment.Our results help elucidate the mechanisms of ANSD and may lead to the provision of novel therapies. | YUE QIU HONGYANG WANG HUAYE PAN JING GUAN LEI YAN MINGJIE FAN HUI ZHOU XUANHAO ZHOU KAIWEN WU ZEXIAO JIA QIANQIAN ZHUANG ZHAOYING LEI MENGYAO LI XUE DING AIFU LIN YONG FU DONG ZHANG QIUJU WANG QINGFENG YAN | 2023 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2023，24，2： | 0 |
