| 1 | β-MnO_(2) with proton conversion mechanism in rechargeable zinc ion battery显示文摘Rechargeable aqueous zinc ion battery(RAZIB)is a promising energy storage system due to its high safety,and high capacity.Among them,manganese oxides with low cost and low toxicity have drawn much attention.However,the under-debate proton reaction mechanism and unsatisfactory electrochemical performance limit their applications.Nanorod b-MnO_(2) synthesized by hydrothermal method is used to investigate the reaction mechanism.As cathode materials for RAZIB,the Zn//b-MnO_(2) delivers 355 mA h g^(-1)(based on cathode mass)at0.1 A g^(-1),and retain 110 mA h g^(-1) after 1000 cycles at 0.2 A g^(-1).Different from conventional zinc ion insertion/extraction mechanism,the proton conversion and Mn ion dissolution/deposition mechanism of b-MnO_(2) is proposed by analyzing the evolution of phase,structure,morphology,and element of b-MnO_(2) electrode,the pH change of electrolyte and the determination of intermediate phase MnO OH.Zinc ion,as a kind of Lewis acid,also provides protons through the formation of ZHS in the proton reaction process.This study of reaction mechanism provides a new perspective for the development of Zn//MnO_(2) battery chemistry. | Wenbao Liu Xiaoyu Zhang Yongfeng Huang Baozheng Jiang Ziwen Chang Chengjun Xu Feiyu Kang | 2021 | Journal of Energy Chemistry2021,30,5: | 6 |
| 2 | High-Performance Aqueous Zinc-Ion Batteries Realized by MOF Materials显示文摘Rechargeable aqueous zinc-ion batteries(ZIB s) have been gaining increasing interest for large-scale energy storage applications due to their high safety,good rate capability,and low cost.However,the further development of ZIB s is impeded by two main challenges:Currently reported cathode materials usually suffer from rapid capacity fading or high toxicity,and meanwhile,unstable zinc stripping/plating on Zn anode seriously shortens the cycling life of ZIBs.In this paper,metal-organic framework(MOF) materials are proposed to simultaneously address these issues and realize high-performance ZIB s with Mn(BTC) MOF cathodes and ZIF-8-coated Zn(ZIF-8@Zn) anodes.Various MOF materials were synthesized,and Mn(BTC) MOF was found to exhibit the best Zn^2+-storage ability with a capacity of 112 mAh g^-1.Zn^2+ storage mechanism of the Mn(BTC) was carefully studied.Besides,ZIF-8@Zn anodes were prepared by coating ZIF-8 MOF material on Zn foils.Unique porous structure of the ZIF-8 coating guided uniform Zn stripping/plating on the surface of Zn anodes.As a result,the ZIF-8@Zn anodes exhibited stable Zn stripping/plating behaviors,with 8 times longer cycle life than bare Zn foils.Based on the above,high-performance aqueous ZIBs were constructed using the Mn(BTC) cathodes and the ZIF-8@Zn anodes,which displayed an excellent long-cycling stability without obvious capacity fading after 900 charge/discharge cycles.This work provides a new opportunity for high-performance energy storage system. | Xuechao Pu Baozheng Jiang Xianli Wang Wenbao Liu Liubing Dong Feiyu Kang Chengjun Xu | 2020 | Nano-Micro Letters2020,12,11: | 5 |
| 3 | ISAR Echoes Coherent Processing and Imaging显示文摘The general approach to ISAR imaging is Range-doppler (RD) imaging approach. For this approach,the Translational motion compensation (TMC) is firstly obtained by envelope alignment and autofocus, so the target can be treated as a rotating target for the next processing. But in this method, scatterers' Migration through resolution cells (MTRC) caused by rotational motion is neglected. However in practice, MTRC exists with the improvement of resolution or for big target. For MTRC compensation, the keystone transformation in SAR is used inthis paper. Before the keystone transformation, it is demanded that the rawdata is coherent, while in fact, the ISAR rawdata is usually not. So a coherent processing of rawdata is proposed. In this paper, the coherent processing of rawdata is firstly done and the next step is to correct MTRC. After using multi-component Amplitude modulation and Linear frequency modulation (AM-LFM) parameter estimation method, the Range-Instantaneous Doppler(RID) ISAR image is obtained. The effectiveness of this algorithm is validated by the processing of simulation data. | XINGMengdao LANJinqiao BAOZheng LIAOGuisheng | 2004 | Chinese Journal of Electronics2004,13,2: | 3 |
| 4 | Correction of Migration Through Resolution Cell in ISAR Imaging显示文摘For ISAR imaging-radar, after the translation motion compensated, the target can be changed to turntable and the R-D (Range-Doppler) algorithm usually adopted is based on small target flying steadily, with the assumption that all of the scatterers are not migrated through their range cells. But for maneuvering target this assumption is not satisfied, as the Doppler frequency is time varying. Actually, to obtain the cross-range resolution of dozens of centimeters for the large-scale or medium targets, especially for S or L wave band, with wave length so short, MTRC (the Migration through resolution cell)would occur on both fringes of the ISAR imaging. The Doppler migration is basically caused by nonuniform rotation of several parts of the target, so that the Doppler frequency of each scatterer is time varying, which can be accumulated coherently by the method of time-frequency analysis in order to get instant range-Doppler image. In this paper, the reason that causes migration through resolution cell is discussed, and a compensating algorithm is proposed. The method of time-frequency analysis to every range cell of scattererer is applied to estimate its instant frequency after range compressing and MTRC correcting,so that the quadratic term can be adjusted. Simulated data and real data prove that this method is effective. | JIANGZhenglin XINGMengdao BAOZheng | 2004 | Chinese Journal of Electronics2004,13,2: | 2 |
| 5 | A Proxy Blind Signature Scheme Based on DLP显示文摘A proxy signature scheme allows an original signer to delegate his signing capability to a proxy signer who can sign on behalf of the original signer. A blind signature is the concept with a salient feature that the signer can not make a linkage between the blind signature and the identity of the requester. Proxy signature and blind signature are used widely in electronic commerce. With satisfying the security properties of both two signatures, a new proxy blind signature scheme based on discrete logarithm problem is proposed. | YU Baozheng XU Congwei | 2007 | Wuhan University Journal of Natural Sciences2007,12,1: | 2 |
| 6 | Some properties of the alternating separation (AS), alternating projection (AP) and ASAP algorithm显示文摘This paper analyzes some properties of the alternating separation (AS) and alternating projection (AP) algorithm. The analysis shows that AS converges to the optimal point steadily but slowly, while AP converges to the optimal point quickly but is prone to immersing into the local extreme of the maximum likelihood (ML) criterion. To avoid their disadvantages and make use of their advantages, ASAP, which is the combination of AS and AP, is proposed. Simulation results show that the ASAP algorithm has the ability of estimating the direction of arrival more accurately and converging to optimal point more quickly. | SHAOChao LUGuangyue BAOZheng | 2004 | Science in China(Series F)2004,47,4: | 1 |
| 7 | A NOVEL DIRECTION OF ARRIVAL ESTIMATOR显示文摘A Direction Of Arrival(DOA) estimator based on the signal separation principle is introduced, and one of representative multidimensional estimators is established by introducing Matrix Operator projection signal steering Vector Excision(MOVE) operation. Thanks to Alternating Separation (AS) technique, the multidimensional problem is transformed into a series of one-dimensional optimal ones. Furthermore, an equivalent simplified implementation of the AS is obtained. Finally the definiteness and uniqueness of the estimator are analyzed. | ShaoChao LuGuangyue BaoZheng | 2004 | Journal of Electronics(China)2004,21,2: | 1 |

| 12 | An Adaptive Filtering Algorithm to Despeckle SAR Images Based on Scale Space Correlation显示文摘Based on the scale space correlation in wavelet domain, a new adaptive filtering algorithm is proposed to remove speckle in SAR images in this paper. This method decomposes SAR images into several scales with Stationary wavelet transform (SWT) and in every detail sub-image we use the idea of the scale space correlation to differentiate the edge information of detail from the noisy images. To deal with the edge information of points, the normal Wiener filter is used; to process the noisy points in homogeneous areas, the Bayesian soft threshold is applied to reduce speckle. After processed with this algorithm, SAR images can not only achieve more satisfied despeckling effect than other conventional methods but also show a good performance of preserving details and texture information. Additionally this algorithm can be more easily performed and has a lower computation burden so it has a widely applicability. | RENLu XINGMengdao BAOZheng | 2005 | Chinese Journal of Electronics2005,14,2: | 0 |

| 14 | Chromosome-scale genome assembly of Prunus pusilliflora provides novel insights into genome evolution, disease resistance, and dormancy release in Cerasus L.显示文摘Prunus pusilliflora is a wild cherry germplasm resource distributed mainly in Southwest China.Despite its ornamental and economic value,a high-quality assembled P.pusilliflora genome is unavailable,hindering our understanding of its genetic background,population diversity,and evolutionary processes.Here,we de novo assembled a chromosome-scale P.pusilliflora genome using Oxford Nanopore,Illumina,and chromosome conformation capture sequencing.The assembled genome size was 309.62 Mb,with 76 scaffolds anchored to eight pseudochromosomes.We predicted 33035 protein-coding genes,functionally annotated 98.27%of them,and identified repetitive sequences covering 49.08%of the genome.We found that P.pusilliflora is closely related to Prunus serrulata and Prunus yedoensis,having diverged from them∼41.8 million years ago.A comparative genomic analysis revealed that P.pusilliflora has 643 expanded and 1128 contracted gene families.Furthermore,we found that P.pusilliflora is more resistant to Colletotrichum viniferum,Phytophthora capsici,and Pseudomonas syringae pv.tomato(Pst)DC3000 infections than cultivated Prunus avium.P.pusilliflora also has considerably more nucleotide-binding site-type resistance gene analogs than P.avium,which explains its stronger disease resistance.The cytochrome P450 and WRKY families of 263 and 61 proteins were divided into 42 and 8 subfamilies respectively in P.pusilliflora.Furthermore,81 MADS-box genes were identified in P.pusilliflora,accompanying expansions of the SVP and AGL15 subfamilies and loss of the TM3 subfamily.Our assembly of a high-quality P.pusilliflora genome will be valuable for further research on cherries and molecular breeding. | Songtao Jiu Baozheng Chen Xiao Dong Zhengxin Lv Yuxuan Wang Chunjin Yin Yan Xu Sen Zhang Jijun Zhu Jiyuan Wang Xunju Liu Wanxia Sun Guoqian Yang Meng Li Shufeng Li Zhuo Zhang Ruie Liu Lei Wang Muhammad Aamir Manzoor Quero-García José Shiping Wang Yahui Lei Ling Yang Elisabeth Dirlewanger Yang Dong Caixi Zhang | 2023 | Horticulture Research2023,10,5: | 0 |
| 15 | FAST CONVERGENT MONTE CARLO RECEIVER FOR OFDM SYSTEMS显示文摘The paper investigates the problem of the design of an optimal Orthogonal Fre- quency Division Multiplexing (OFDM) receiver against unknown frequency selective fading. A fast convergent Monte Carlo receiver is proposed. In the proposed method, the Markov Chain Monte Carlo (MCMC) methods are employed for the blind Bayesian detection without channel es- timation. Meanwhile, with the exploitation of the characteristics of OFDM systems, two methods are employed to improve the convergence rate and enhance the efficiency of MCMC algorithms. One is the integration of the posterior distribution function with respect to the associated channel parameters, which is involved in the derivation of the objective distribution function; the other is the intra-symbol differential coding for the elimination of the bimodality problem resulting from the presence of unknown fading channels. Moreover, no matrix inversion is needed with the use of the orthogonality property of OFDM modulation and hence the computational load is significantly reduced. Computer simulation results show the effectiveness of the fast convergent Monte Carlo receiver. | WuLili LiaoGuisheng BaoZheng ShangYong | 2005 | Journal of Electronics(China)2005,22,3: | 0 |
| 16 | Neural Network Learning for Principal Component Analysis: A Multistage Decomposition Approach显示文摘This paper presents a novel neural network model for finding the principal components of an Ndimensional data stream. This neural network consists of r (≤N) neurons, where the i-th neuron has only N - i+1 weights and an N- i+1 dimensional input vector, while each neuron in most of the relative classical neural networks includes N weights and an N dimensional input vector. All the neurons are trained by the NIC algorithm under the single component case^[7] so as to get a series of dimension-reducing principal components in which the dimension number of the i-th principal component is N- i+1. In multistage dimension-reducing processing, the weight vector of i-th neuron is always orthogonal to the subspace constructed from the weight vectors of the first i-1 neurons. By systematic reconstruction technique, wecan recover all the principal components from a series of dimension-reducing ones. Its remarkable advantage is that its computational efficiency of the neural network learning based on the Novel information criterion (NIC) is improved and the weight storage is reduced, by the multistage dimension-reducing processing (multistage decomposition)for the covariance matrix or the input vector sequence. In addition, we study several important properties of the NIC learning algorithm. | FENGDazheng ZHANGXianda BAOZheng | 2004 | Chinese Journal of Electronics2004,13,1: | 0 |
