| 3 | Recommendations for the diagnosis and treatment of paroxysmal kinesigemc dyskinesia: an expert consensus in China显示文摘Paroxysmal dyskinesias are a group of neurological diseases characterized by intermittent episodes of involuntary movements with different causes.Paroxysmal kinesigenic dyskinesia(PKD)is the most common type of paroxysmal dyskinesia and can be divided into primary and secondary types based on the etiology.Clinically,PKD is characterized by recurrent and transient attacks of involuntary movements precipitated by a sudden voluntary action.The major cause of primary PKD is genetic abnormalities,and the inheritance pattern of PKD is mainly autosomal-dominant with incomplete penetrance.The proline-rich transmembrane protein 2(PRRT2)was the first identified causative gene of PKD,accounting for the majority of PKD cases worldwide.An increasing number of studies has revealed the clinical and genetic characteristics,as well as the underlying mechanisms of PKD.By seeking the views of domestic experts,we propose an expert consensus regarding the diagnosis and treatment of PKD to help establish standardized clinical evaluation and therapies for PKD.In this consensus,we review the clinical manifestations,etiology,clinical diagnostic criteria and therapeutic recommendations for PKD,and results of genetic analyses in PKD patients performed in domestic hospitals. | Li Cao Xiaojun Huang Ning Wang Zhiying Wu Cheng Zhang Weihong Gu Shuyan Cong Jianhua Ma Ling Wei Yanchun Deng Qi Fang Qi Niu Jin Wang Zhaoxia Wang You Yin Jinyong Tian Shufen Tian Hongyan Bi Hong Jiang Xiaorong Liu Yang Lu Meizhen Sun Jianjun Wu Erhe Xu Tao Chen Tao Chen Xu Chen Wei Li Shujian Li Qinghua Li Xiaonan Song Ying Tang Ping Yang Yun Yang Min Zhang Xiong Zhang Yuhu Zhang Ruxu Zhang Yi Ouyang Jintai Yu Quanzhong Hu Qing Ke Yuanrong Yao Zhe Zhao Xiuhe Zhao Guohua Zhao Furu Liang Nan Cheng Jianhong Han Rong Peng Shengdi Chen Beisha Tang | 2021 | Translational Neurodegeneration2021，10，1： | 1 |
| 4 | Improving the Facility Soil by Combining Soil Amendment with Agronomic Measures显示文摘[Objectives]To study the remediation methods of secondary salinization and cadmium pollution in facility soil.[Methods]Two kinds of soil amendments,potassium fulvic acid and limestone powder,were selected to be applied alone or combined together to plant maize to carry out field experiments.Their effects on watermelon yield,watermelon cadmium content,soil available nitrogen,phosphorus,potassium and water-soluble salts were studied.[Results]The application of potassium fulvic acid,limestone powder and their combined application increased the yield and soluble solids of watermelon to different degrees.The contents of seven heavy metals including cadmium,copper,zinc,arsenic,lead,mercury and chromium in the watermelon of all treatments were all lower than the food safety limit stipulated in the national standard.During the harvest period of maize seedlings,all treatments could increase soil pH and decrease soil cadmium availability.In particular,3000 kg/ha of limestone powder and 1500 kg/ha of potassium fulvic acid had the best effect on reducing soil available cadmium content.In reducing soil available cadmium content,there were significant differences between single application of amendment and combined application treatments.In addition,compared with the control CK,all treatments decreased soil available nitrogen,phosphorus,potassium and water-soluble salt content.[Conclusions]Potassium fulvic acid,limestone powder and their combined application can increase the yield of watermelon,and can significantly reduce the available cadmium,nitrogen,phosphorus,potassium and water-soluble salt content in the facility soil of maize cultivation. | Yuyi HUANG Yanfei HUANG Mei PANG Guifen CHEN Bin LIU Xiaoqing OU Xiuhe ZHAO Yueyue ZHOU | 2022 | Asian Agricultural Research2022，14，7： | 0 |
| 5 | Permanent Magnet Assisted Synchronous Reluctance Motor with Asymmetric Rotor for High Torque Performance显示文摘Permanent magnet assisted synchronous reluctance motor(PMA-SynRM)is a kind of high torque density energy conversion device widely used in modern industry.In this paper,based on the basic topology of PMA-SynRM,a novel PMA-SynRM of asymmetric rotor with position-biased magnet is proposed.The asymmetric rotor design with position-biased magnet realizes the concentration of magnetic field lines in the motor air gap to obtain higher electromagnetic torque,and makes both of magnetic and reluctance torque obtain the peak value at the same current phase angle.The asymmetric rotor configuration is theoretically illustrated by space vector diagram,and the feasibility of high torque performance of the motor is verified.Through the finite element simulation,the effect of the side barrier on output torque and the Mises stress under the rotor asymmetrical design are analyzed.Then the motor characteristics including airgap flux density,back EMF,magnetic torque,reluctance torque,torque ripple,losses,and efficiency are calculated for both the basic and proposed PMA-SynRMs.The results show that the proposed PMA-SynRM has higher torque and efficiency than the basic topology.Moreover,the torque ripple of the proposed PMA-SynRM is reduced by the method with harmonic current injection,and the torque characteristics in the whole current cycle are analyzed.Finally,the endurance to avoid PM demagnetization is confirmed based on the PM remanence calculation. | Chengwu Diao Wenliang Zhao Yan Liu Xiuhe Wang | 2023 | CES Transactions on Electrical Machines and Systems2023，7，2： | 0 |
| 6 | Torque Improvement of Spoke-type Permanent Magnet Motor with Auxiliary Stator Using Harmonic Current Control Strategy显示文摘The spoke-type permanent magnet motor with auxiliary stator exhibits high torque performance owing to the flux focus effects.To further improve its torque density,this paper proposes a control method by using harmonic current strategy.Based on the theoretical analysis,a 3-D torque look-up table by dq-axis current and electrical angle is established with the aid of the finite element method(FEM).The maximum torque per ampere curve at each rotor position is identified and summarized to adequately indicate the relationship between torque and current amplitude of the motor.Through theoretical derivation,it is concluded that the minimum torque cost curve is the contour line of?Te/?i2,which can be employed to identify the harmonic current for torque density improvement.Compared to traditional strategies,the proposed control strategy can increase torque density of forward and reverse torque by 1.22%and 1.40%,respectively.The experimental results verify the analysis and simulation results,as well as prove the effectiveness of the proposed strategy. | Hao Wu Wenliang Zhao Zheng Li Xiuhe Wang | 2023 | CES Transactions on Electrical Machines and Systems2023，7，2： | 0 |
| 7 | Towards Order-Preserving and Zero-Copy Communication on Shared Memory for Large Scale Simulation显示文摘Parallel simulation generally needs efficient,reliable and order-preserving communication.In this article,a zero-copy,reliable and order-preserving intra-node message passing approach named ZeROshm is proposed.This mechanism partitions shared memory into segments assigned to processes for receiving messages.Each segment consists of two levels of index L1 and L2 that recordes the order of messages in the host segment,and the processes also read from and write to the segments directly according to the indexes,thereby eliminating allocating and copying buffers.As experimental results show,ZeROshm exhibits nearly equivalent performance to message passing interface(MPI)for small message and superior performance for large message.Specifically,ZeROshm costs less time by 43%,40%and 55%respectively in pure communication,communication with contention and real PHOLD simulation within a single node.Additionally,in hybrid environment,the combination of ZeROshm and MPI also shorten the execution time of PHOLD simulation by about 42%compared to pure MPI. | LI Xiuhe SHEN Yang LIN Zhongwei ZHAO Shunkai SHI Qianqian DAI Shaoqi | 2023 | Chinese Journal of Electronics2023，32，5： | 0 |

| 10 | 3D Joint inversion of gravity and gravity tensor data显示文摘The processing and interpretation of gravity and gradient data plays an important role in geophysics.The cross gradient joint inversion is usually used for achieving structure coupling of multiple geophysical models. In order to realize the coupling of gravity and gravity tensor data,the authors analyzed each component.The results show that different types of data contain different direction information,and derived the joint inversion based on cross gradient function and applied it to model data. The theoretical model results show that the cross gradient method can reduce the multi solution and significantly improve the resolution of the inversion.The method was also applied to inverse the gravity tensor data in Vinton salt dome,showing that this method can get higher resolution results than the separate linear inversion,and be closer to the real density from drilling data. | ZHAO Simin GAO Xiuhe QIAO Zhongkun JIANG Dandan ZHOU Fei LIN Song | 2018 | Global Geology2018，21，1： | 0 |
