| 1 | Effect of annealing treatment on the structural, optical, and electrical properties of Al-doped ZnO thin films显示文摘Highly conductive and transparent Al-doped ZnO (AZO) thin films were prepared from a zinc target containing Al (1.5 wt.%) by direct current (DC) and radio frequency (RF) reactive magnetron sputtering. The structural, optical, and electrical properties of AZO films as-deposited and submitted to annealing treatment (at 300 and 400°C, respectively) were characterized using various techniques. The experimental results show that the properties of AZO thin films can be further improved by annealing treatment. The crystallinity of ZnO films improves after annealing treatment. The transmittances of the AZO thin films prepared by DC and RF reactive magnetron sputtering are up to 80% and 85% in the visible region, re- spectively. The electrical resistivity of AZO thin films prepared by DC reactive magnetron sputtering can be as low as 8.06 × 10?4 ??cm after annealing treatment. It was also found that AZO thin films prepared by RF reactive magnetron sput- tering have better structural and optical properties than that prepared by DC reactive magnetron sputtering. | LI Li FANG Liang CHEN Ximing LIU Gaobin LIU Jun YANG Fengfan FU Guangzong KONG Chunyang | 2007 | Rare Metals2007，26，3： | 11 |
| 2 | CD147 antibody specifically and effectively inhibits infection and cytokine storm of SARS-CoV-2 and its variants delta,alpha,beta,and gamma显示文摘SARS-CoV-2 mutations contribute to increased viral transmissibility and immune escape,compromising the effectiveness of existing vaccines and neutralizing antibodies.An in-depth investigation on COVID-19 pathogenesis is urgently needed to develop a strategy against SARS-CoV-2 variants.Here,we identified CD147 as a universal receptor for SARS-CoV-2 and its variants.Meanwhile,Meplazeumab,a humanized anti-CD147 antibody,could block cellular entry of SARS-CoV-2 and its variants-alpha,beta,gamma,and delta,with inhibition rates of 68.7,75.7,52.1,52.1,and 62.3%at 60μg/ml,respectively.Furthermore,humanized CD147 transgenic mice were susceptible to SARS-CoV-2 and its two variants,alpha and beta.When infected,these mice developed exudative alveolar pneumonia,featured by immune responses involving alveoli-infiltrated macrophages,neutrophils,and lymphocytes and activation of IL-17 signaling pathway.Mechanistically,we proposed that severe COVID-19-related cytokine storm is induced by a'spike protein-CD147-CyPA signaling axis':Infection of SARS-CoV-2 through CD147 initiated the JAK-STAT pathway,which further induced expression of cyclophilin A(CyPA);CyPA reciprocally bound to CD147 and triggered MAPK pathway.Consequently,the MAPK pathway regulated the expression of cytokines and chemokines,which promoted the development of cytokine storm.Importantly,Meplazumab could effectively inhibit viral entry and inflammation caused by SARS-CoV-2 and its variants.Therefore,our findings provided a new perspective for severe COVID-19-related pathogenesis.Furthermore,the validated universal receptor for SARS-CoV-2 and its variants can be targeted for COVID-19 treatment. | Jiejie Geng Liang Chen Yufeng Yuan Ke Wang Youchun Wang Chuan Qin Guizhen Wu Ruo Chen Zheng Zhang Ding Wei Peng Du Jun Zhang Peng Lin Kui Zhang Yongqiang Deng Ke Xu Jiangning Liu Xiuxuan Sun Ting Guo Xu Yang Jiao Wu Jianli Jiang Ling Li Kun Zhang Zhe Wang Jing Zhang Qingguo Yan Hua Zhu Zhaohui Zheng Jinlin Miao Xianghui Fu Fengfan Yang Xiaochun Chen Hao Tang Yang Zhang Ying Shi Yumeng Zhu Zhuo Pei Fei Huo Xue Liang Yatao Wang Qingyi Wang Wen Xie Yirong Li Mingyan Shi Huijie Bian Ping Zhu Zhi-Nan Chen | 2021 | Signal Transduction and Targeted Therapy2021，6，10： | 6 |
| 3 | Joint Design of QC-LDPC Codes for Coded Relay Cooperation显示文摘This paper proposes an effective method to jointly design girth-4 cycle-free Quasi-cyclic(QC) Lowdensity parity-check(LDPC) codes for multi-relay cooperation in a Rayleigh fading channel, where the joint iterative decoding by Min-sum algorithm(MSA) based on the introduced joint Tanner graph is also presented at the destination. Theoretical analysis and simulation show that the proposed QC-LDPC coded cooperation outperforms the randomly coded cooperation under the same conditions. | TANG Lei YANG Fengfan ZHANG Shunwai SAQIB Ejaz LUO Lin | 2016 | Chinese Journal of Electronics2016，25，1： | 3 |
| 4 | JOINT ITERATIVE DECODING FOR SIMPLE-ENCODING SYSTEMATIC IRREGULAR-LDPC-BASED CODED COOPERATION IN NON-IDEAL RELAY CHANNEL显示文摘In this paper, a new kind of simple-encoding irregular systematic LDPC codes suitable for one-relay coded cooperation is designed, where the proposed joint iterative decoding is effectively performed in the destination which is in accordance with the corresponding joint Tanner graph characterizing two different component LDPC codes used by the source and relay in ideal and non-ideal relay cooperations. The theoretical analysis and simulations show that the coded cooperation scheme obviously outperforms the coded non-cooperation one under the same code rate and decoding complex. The significant performance improvement can be virtually credited to the additional mutual exchange of the extrinsic information resulted by the LDPC code employed by the source and its counterpart used by the relay in both ideal and non-ideal cooperations. | Chen Jingwen Yang Fengfan Luo Lin Tho Le-Ngoc | 2010 | Journal of Electronics(China)2010，27，3： | 3 |
| 5 | Research progress of localization technique assisted neuroendoscopy for cerebral hemorrhage显示文摘Neurosurgeons who perform intracere-bral hemorrhage(ICH)evacuation procedures have lim-ited options for monitoring hematoma evacuation and intraoperatively assessing residual-hematoma burden.In recent years,neuroendoscope-assisted,minimally inva-sive surgery for spontaneous ICH is simple and effective and becoming increasingly common.Many methods are applied in neuronavigation-assisted surgery for ICH evac-uation,such as neuroendoscopy,three-dimensional(3D)reconstruction,intraoperative ultrasound,and stereotac-tic craniotomy.Compared with a traditional craniotomy operation,hematoma removal(using methods of accurate localization)can reduce iatrogenic damage,protect white matter,and shorten patients’recovery time.This paper mainly outlines the treatment of basal ganglia-cerebral hemorrhage with neuroendoscopy assistance using local-ization techniques. | Xiaodong Wang Fengfan Bai Dianfang Zheng Gang Yang | 2021 | Journal of Translational Neuroscience2021，6，3： | 1 |

| 10 | The novel transmission scheme with CAT Ethernet cable and SFP for White Rabbit显示文摘Background White Rabbit(WR)is a deterministic Ethernet-based network for general-purpose data transfer and subnanosecond time synchronization in large distributed systems.WR has been used in Large Hadron Collider and Large High-Altitude Air Shower Observatory for physics experiment.Purpose WR mainly uses the optical fiber for data transmission between WR devices.Commercial off-the-shelf Direct Attach Cable is not suitable for WR network at 100m level distance.Considering the lower cost of Category(CAT)Ethernet cable compared to optical fiber and the demand of remote power supply in distributed system at 100m level length,we developed a novel transmission scheme with CAT Ethernet cable for WR.Methods The novel transmission scheme uses the CAT Ethernet cable and small form-factor pluggable connector which is compatible with the optical links.This scheme only uses two pairs of twisted lines in the CAT Ethernet cable for data uplink and downlink.The other two pairs of twisted lines are used for remote power supply.Results and conclusion The novel transmission scheme could use the CAT Ethernet cable to complete remote power supply and time synchronization with expected time offset of less than 100 ps and standard deviation of less than 20 ps in the WR distributed system.The distance of distributed nodes could be 80m with one CAT 7 Ethernet cable or 150m with relay transceiver connecting two CAT 7 Ethernet cables.In the short-distance scenarios,the novel transmission scheme has lower cost than the optical fiber and additional power supply function. | Yanke Cai Jie Zhang Yunhua Sun Fengfan Yang Xiaoshan Jiang Changge Zi Cong He Shanshan Cui | 2021 | Radiation Detection Technology and Methods2021，5，2： | 0 |
| 11 | Advances in arterial spin labeled cerebral perfusion imaging in cerebrovascular diseases显示文摘Cerebrovascular disease is a disease with high morbidity,disability and mortality rates,which seri-ously affects the daily life of patients and is a heavy burden on families and society.Arterial spin labeling(ASL)is a magnetic resonance imaging(MRI)technology that uses the magnetic labeling of hydrogen atoms in arterial blood as tracers to noninvasively evaluate brain blood flow.ASL does not require injection of an exogenous contrast agent,and has the advantages of no radiation,simplicity and low cost.In cerebrovascular diseases,ASL can evaluate the collateral cerebrovascular circulation and abnormal perfusion of brain tissue,which can provide a reliable basis for early diagnosis and clinical decision-making.This study reviewed ASL and its application in the diagnosis,treatment and prognosis of cerebrovascular diseases. | Xiaodong Wang Gang Yang Fengfan Bai | 2020 | Journal of Translational Neuroscience2020，5，4： | 0 |

| 13 | HIGH-PERFORMANCE SIMPLE-ENCODING GENERATOR-BASED SYSTEMATIC IRREGULAR LDPC CODES AND RESULTED PRODUCT CODES显示文摘Low-Density Parity-Check (LDPC) code is one of the most exciting topics among the coding theory community.It is of great importance in both theory and practical communications over noisy channels.The most advantage of LDPC codes is their relatively lower decoding complexity compared with turbo codes,while the disadvantage is its higher encoding complexity.In this paper,a new ap- proach is first proposed to construct high performance irregular systematic LDPC codes based on sparse generator matrix,which can significantly reduce the encoding complexity under the same de- coding complexity as that of regular or irregular LDPC codes defined by traditional sparse parity-check matrix.Then,the proposed generator-based systematic irregular LDPC codes are adopted as con- stituent block codes in rows and columns to design a new kind of product codes family,which also can be interpreted as irregular LDPC codes characterized by graph and thus decoded iteratively.Finally, the performance of the generator-based LDPC codes and the resultant product codes is investigated over an Additive White Gaussian Noise (AWGN) and also compared with the conventional LDPC codes under the same conditions of decoding complexity and channel noise. | Yang Fengfan Ye Ming Luo Lin | 2007 | Journal of Electronics(China)2007，24，5： | 0 |
