| 1 | A novel functional electrical stimulation-control system for restoring motor function of post-stroke hemiplegic patients显示文摘Hemiparesis is one of the most common consequences of stroke. Advanced rehabilitation techniques are essential for restoring motor function in hemiplegic patients. Functional electrical stimulation applied to the affected limb based on myoelectric signal from the unaffected limb is a promising therapy for hemiplegia. In this study, we developed a prototype system for evaluating this novel functional electrical stimulation-control strategy. Based on surface electromyography and a vector machine model, a self-administered, multi-movement, force-modulation functional electrical stimulation-prototype system for hemiplegia was implemented. This paper discusses the hardware design, the algorithm of the system, and key points of the self-oscillation-prone system. The experimental results demonstrate the feasibility of the prototype system for further clinical trials, which is being conducted to evaluate the efficacy of the proposed rehabilitation technique. | Zonghao Huang Zhigong Wang Xiaoying Lv Yuxuan Zhou Haipeng Wang Sihao Zong | 2014 | Neural Regeneration Research2014，9，23： | 4 |
| 2 | Towards Friction Stir Remanufacturing of High‑Strength Aluminum Components显示文摘Volumetric defects in high-strength aluminum alloy components were repaired via friction stir remanufacturing(FSR).Various consumable pins made of AA7075-T6 were designed.Top diameters of the consumable pins afected material fow,which ensured that the materials at the repairing interface were forged to metallurgical bonding.Conical angles determined load transfer besides material fow,which afected the fracture of the pins before the dwelling stage.Sound repaired components were achieved when the conical angle of the consumable pin was 1°larger than that of the volumetric defect.The ultimate tensile strength and elongation of the repaired components reached 445.9 MPa and 9.6%,respectively.The design criteria of the consumable pin in the FSR was established,which provided valuable references to repair volumetric defects in high-strength aluminum components. | Xiangchen Meng Yuming Xie Xiaotian Ma Mingyang Liang Xiaoyang Peng Shiwei Han Lei Kan Xin Wang Sihao Chen Yongxian Huang | 2023 | Acta Metallurgica Sinica(English Letters)2023，36，1： | 1 |

| 5 | Nonlinear optical properties of CsPbCl_(x)Br_(3-x)nanocrystals embedded glass显示文摘All-inorganic perovskite has attracted significant attention due to its excellent nonlinear optical characteristics.Stable and low-toxic perovskite materials have great application prospects in optoelectronic devices.Here,we study the nonlinear optical properties of CsPbCl_(x)Br_(3-x)(x=1,1.5,2)nanocrystals(NCs)glass by open-aperture Z-scan.It is found that the two-(2 PA)and three-photon absorption(3 PA)intensity can be adjusted by the treatment temperature and the ratio of halide anions.The perovskite NCs glass treated at a high temperature has better crystallinity,resulting in stronger nonlinear absorption performance.In addition,the value of the 2 PA parameter of CsPbCl_(1.5)Br_(1.5)NCs glasses decreases when the incident pump intensity increases,which is ascribed to the saturation of 2 PA and population inversion.Finally,the research results show that the 2 PA coefficient(0.127 cm GW-1)and 3 PA coefficient(1.21×10^(-5)cm^(3)GW-2)of CsPbCl_(1)Br_(2)NCs glass with high Br anion content are larger than those of CsPbCl_(2)Br_(1)and CsPbCl_(1.5)Br_(1.5)NCs glasses.This is mainly due to the greater influence of Br anions on the symmetry of the perovskite structure,which leads to the redistribution of delocalized electrons.The revealed adjustable nonlinear optical properties of perovskite NCs glass are essential for developing stable and high-performance nonlinear optical devices. | CHENJING QUAN XIAO XING SIHAO HUANG MENGFEIFEI JIN TONGCHAO SHI ZEYU ZHANG WEIDONG XIANG ZHANSHAN WANG YUXIN LENG | 2021 | Photonics Research2021，9，9： | 1 |
| 6 | Thermo-Economic Performance of Geothermal Driven High-Temperature Flash Tank Vapor Injection Heat Pump System:A Comparison Study显示文摘Process heating constitutes a significant share of final energy consumption in the industrial sector around the world.In this paper,a high-temperature heat pump(HTHP)using flash tank vapor injection technology(FTVI)is proposed to develop low-temperature geothermal source for industrial process heating with temperature above 100°C.With heat sink output temperatures between 120°C and 150°C,the thermo-economic performance of the FTVI HTHP system using R1234ze(Z)as refrigerant is analyzed and also compared to the single-stage vapor compression(SSVC)system by employing the developed mathematical model.The coefficient of performance(COP),exergy efficiency(ηexe),net present value(NPV)and payback period(PBP)are used as performance indicators.The results show that under the typical working conditions,the COP andηexe of FTVI HTHP system are 3.00 and 59.66%,respectively,and the corresponding NPV and PBP reach 8.13×106 CNY and 4.13 years,respectively.Under the high-temperature heating conditions,the thermo-economic performance of the FTVI HTHP system is significantly better than that of the SSVC system,and the larger the temperature lift,the greater the thermo-economic advantage of the FTVI HTHP system.Additionally,the FTVI HTHP system is more capable than the SSVC system in absorbing the financial risks associated with changes of electricity price and natural gas price. | Huashan Li Xiaoshuang Zhao Sihao Huang Lingbao Wang Jiongcong Chen | 2023 | Energy Engineering2023，120，8： | 0 |
| 7 | A performance-based hybrid deep learning model for predicting TBM advance rate using Attention-ResNet-LSTM显示文摘The technology of tunnel boring machine(TBM)has been widely applied for underground construction worldwide;however,how to ensure the TBM tunneling process safe and efficient remains a major concern.Advance rate is a key parameter of TBM operation and reflects the TBM-ground interaction,for which a reliable prediction helps optimize the TBM performance.Here,we develop a hybrid neural network model,called Attention-ResNet-LSTM,for accurate prediction of the TBM advance rate.A database including geological properties and TBM operational parameters from the Yangtze River Natural Gas Pipeline Project is used to train and test this deep learning model.The evolutionary polynomial regression method is adopted to aid the selection of input parameters.The results of numerical exper-iments show that our Attention-ResNet-LSTM model outperforms other commonly-used intelligent models with a lower root mean square error and a lower mean absolute percentage error.Further,parametric analyses are conducted to explore the effects of the sequence length of historical data and the model architecture on the prediction accuracy.A correlation analysis between the input and output parameters is also implemented to provide guidance for adjusting relevant TBM operational parameters.The performance of our hybrid intelligent model is demonstrated in a case study of TBM tunneling through a complex ground with variable strata.Finally,data collected from the Baimang River Tunnel Project in Shenzhen of China are used to further test the generalization of our model.The results indicate that,compared to the conventional ResNet-LSTM model,our model has a better predictive capability for scenarios with unknown datasets due to its self-adaptive characteristic. | Sihao Yu Zixin Zhang Shuaifeng Wang Xin Huang Qinghua Lei | 2024 | Journal of Rock Mechanics and Geotechnical Engineering2024，16，1： | 0 |
| 8 | Surface ligand modified cesium lead bromide/silica sphere composites for low-threshold upconversion lasing显示文摘In recent years,all-inorganic halide perovskite quantum dots(QDs)have drawn attention as promising candidates for photodetectors,light-emitting diodes,and lasing applications.However,the sensitivity and instability of perovskite to moisture and heat seriously restrict their practical application to optoelectronic devices.Recently,a facile ligand-engineering strategy to suppress aggregation by replacing traditional long ligands oleylamine(OAm)during the hot injection process has been reported.Here,we further explore its thermal stability and the evolution of photoluminescence quantum yield(PLQY)under ambient environment.The modified CsPbBr_(3)QDs film can maintain 33%of initial PL intensity,but only 17%is retained in the case of unmodified QDs after 10 h continuous heating.Further,the obtained QDs with higher initial PLQY(91.8%)can maintain PLQY to 39.9%after being continuously exposed in air for 100 days,while the PLQY of original QDs is reduced to 5.5%.Furthermore,after adhering CsPbBr3 QDs on the surface of a micro SiO_(2)sphere,we successfully achieve the highly-efficient upconversion random laser.In comparison with the unmodified CsPbBr_(3)QDs,the laser from the modified CsPbBr_(3)QDs presents a decreased threshold of 79.81μJ/cm^(2)and higher quality factor(Q)of 1312.This work may not only provide a facile strategy to synthesize CsPbBr_(3) QDs with excellent photochemical properties but also a bright prospect for high-performance random lasers. | Qian Xiong Sihao Huang Zijun Zhan Juan Du Xiaosheng Tang Zhiping Hu Zhengzheng Liu Zeyu Zhang Weiwei Chen Yuxin Leng | 2022 | Photonics Research2022，10，3： | 0 |
