1Intermediate Spoofing Strategies and Countermeasures显示文摘Intermediate spoofing can impact most off-the-shelf Global Navigation Satellite Systems(GNSS)receivers,therefore low cost detection of such spoofing is very important to protect the reliability of the GNSS receivers used in critical safety and financial applications.This paper presents two strategies to analyze attacks by intermediate spoofing attackers to identify the weaknesses of such attacks.The analyses lead to a code and carrier phase consistency detection method with simulation results showing that this method can indicate the receiver when spoofing has occurred.The method can be used by most receivers,is inexpensive,and requires only a small software upgrade.Yang Gao Hong Li Mingquan Lu Zhenming Feng 2013Tsinghua Science and Technology2013,18,6:7
2Low-complexity method for DOA estimation based on ESPRIT显示文摘A low-complexity method for direction of arrival(DOA) estimation based on estimation signal parameters via rotational invariance technique(ESPRIT) is proposed.Instead of using the cross-correlation vectors in multistage Wiener filter(MSWF),the orthogonal residual vectors obtained in conjugate gradient(CG) method span the signal subspace used by ESPRIT.The computational complexity of the proposed method is significantly reduced,since the signal subspace estimation mainly needs two matrixvector complex multiplications at the iteration of data level.Furthermore,the prior training data are not needed in the proposed method.To overcome performance degradation at low signal to noise ratio(SNR),the expanded signal subspace spanned by more basis vectors is used and simultaneously renders ESPRIT yield redundant DOAs,which can be excluded by performing ESPRIT once more using the unexpanded signal subspace.Compared with the traditional ESPRIT methods by MSWF and eigenvalue decomposition(EVD),numerical results demonstrate the satisfactory performance of the proposed method.Xuebin Zhuang Xiaowei Cui Mingquan Lu Zhenming Feng 2010Journal of Systems Engineering and Electronics2010,21,5:6
3Isolation via enrichment and characterization of ten polymorphic microsatellite loci in the cuttlefish, Sepiella maindroni de Rochebruns显示文摘Ten novel polymorphic microsatellite loci were developed using an enrichment and colony hybridization protocol and characterized for the cuttlefish,Sepiella maindroni.Polymorphism was explored by using 30 individuals from the coastal waters of Zhanjiang,Guangdong province,China,in December 2007.The number of alleles ranged from 5 to 13.The ranges of observed and expected heterozygosity were from 0.578 9 to 1.000 0 and 0.682 8 to 0.925 7,respectively,and the average polymorphic information content (P IC) was 0.778 5.These microsatellite loci will certainly facilitate the detection of the genetic variation and population structure of S.maindroni.WU Changwen CHI Changfeng HE Guangyuan LU Zhenming XU Meiying 2010Acta Oceanologica Sinica2010,29,6:6
4Mitochondrial Genome of Episesarma lafondii(Brachyura:Sesarmidae)and Comparison with Other Sesarmid Crabs显示文摘Complete mitochondrial genomes(mitogenomes)can provide useful information for phylogenetic relationships,gene rearrangement,and molecular evolution.Here,the complete mitogenome of Episesarma lafondii(Brachyura:Grapsoidea:Sesarmidae)was sequenced through next-generation sequencing technique for the first time.The 15640 bp mitogenome contains the entire set of 37 genes and an AT-rich region.The rearrangements of two tRNA genes(tRNA-His and tRNA-Gln)are compared with that in the pancrustacean ground pattern,and the tandem duplication/random loss model was selected to explain the observed gene rearrangements.The phylogenetic results showed that all sesarmid crabs belong to the same group,wherein the genus Episesarma showed the closest relationship with Clistocoeloma.Furthermore,the monophyly of each family was well supported except for Xanthidae,Gecarcinidae,and Homolidae.The correlation between the phylogeny of Sesarmidae species and the gaps in the QIM region was analyzed.Evidently,the gaps between Q and I(Gap3 and between I and M(Gap4)degenerated with the evolution process.In general,the results will contribute to the in-depth understanding of gene rearrangements in Sesarmidae mitogenomes and provide new insights into the phylogeny of Brachyura.ZHANG Ying GAO Yan GONG Li LU Xinting JIANG Lihua LIU Bingjian LIU Liqin LU Zhenming LI Pengfei 2021Journal of Ocean University of China2021,20,6:4
5Highly Dispersed Cobalt Nanoparticles Embedded in Nitrogen-Doped Graphitized Carbon for Fast and Durable Potassium Storage显示文摘Potassium-ion batteries(KIBs)have great potential for applications in large-scale energy storage devices.However,the larger radius of K+leads to sluggish kinetics and inferior cycling performance,severely restricting its practical applicability.Herein,we propose a rational strategy involving a Prussian blue analogue-derived graphitized carbon anode with fast and durable potassium storage capability,which is constructed by encapsulating cobalt nanoparticles in nitrogen-doped graphitized carbon(Co-NC).Both experimental and theoretical results show that N-doping effectively promotes the uniform dispersion of cobalt nanoparticles in the carbon matrix through Co-N bonds.Moreover,the cobalt nanoparticles and strong Co-N bonds synergistically form a threedimensional conductive network,increase the number of adsorption sites,and reduce the diffusion energy barrier,thereby facilitating the adsorption and the diffusion kinetics.These multiple effects lead to enhanced reversible capacities of 305 and 208.6 mAh g^−1 after 100 and 300 cycles at 0.05 and 0.1 A g^−1,respectively,demonstrating the applicability of the Co-NC anode for KIBs.Xiaodong Shi Zhenming Xu Cheng Han Runze Shi Xianwen Wu Bingan Lu Jiang Zhou Shuquan Liang 2021Nano-Micro Letters2021,13,2:4
6Numerically stable method of signal subspace estimation based on multistage Wiener filter显示文摘In this paper,a numerically stable method of signal subspace estimation based on Householder multistage Wiener filter(HMSWF) is proposed.Numerical stability of the method lies on the fact that the Householder matrix in HMSWF ensures the unitary blocking operation and significantly strengthens the orthogonality of basis vectors,especially in the finite-precision implementation.In the following,we analyze the numerical stability of HMSWF and MSWF based on the correlation subtractive structure(CSS-MSWF) by establishing the equivalence between the forward recursion of MSWF and the Arnoldi algorithm in numerical linear algebra.Besides,the equivalence between HMSWF and the Householder QR decomposition(QRD) on the Krylov matrix underlying in MSWF is directly established.Based on the relationship,two theoretical upper bounds of the orthogonality error of basis vectors in signal subspace are obtained and it is demonstrated that the orthogonality of basis vectors based on HMSWF is perfectly preserved by the numerically well-behaved Householder matrix,and the corresponding signal subspace estimation is much more numerically stable than that based on CSS-MSWF.Simulations show the numerical stability of the proposed method of signal subspace estimation by HMSWF.ZHUANG XueBin CUI XiaoWei LU MingQuan FENG ZhenMing 2010Science China(Information Sciences)2010,53,12:4
7Ore Genesis for Stratiform Ore Bodies of the Dongfengnanshan Copper Polymetallic Deposit in the Yanbian Area, NE China:Constraints from LA-ICP-MS in situ Trace Elements and Sulfide S–Pb Isotopes显示文摘The Dongfengnanshan Cu polymetallic deposit is one representative deposit of the Tianbaoshan ore district in the Yanbian area, northeast(NE) China. There occur two types of ore bodies in this deposit, the stratiform ore bodies and veintype ones, controlled by the Early Permian strata and the Late Hercynian diorite intrusion, respectively. Due to the ambiguous genetic type of the stratiform ore bodies, there has been controversy on the relationship between them and veintype ore bodies. To determine the genetic type of stratiform ore bodies, laser ablation inductively coupled plasma mass spectrometry(LA-ICP-MS) in situ trace elements and S–Pb isotope analysis have been carried on the sulfides in the stratiform ore bodies. Compared with that in skarn, Mississippi Valley-type(MVT), and epithermal deposits, sphalerite samples in the stratiform ore bodies of the Dongfengnanshan deposit are significantly enriched in Fe, Mn, and In, while depleted in Ga, Ge, and Cd, which is similar to the sphalerite in volcanic-associated massive sulfide(VMS) deposits. Co/Ni ratio of pyrrhotites in the stratiform ore bodies is similar to that in VMS-type deposits. The concentrations of Zn and Cd of chalcopyrites are similar to those of recrystallized VMS-type deposits. These characteristics also reflect the intermediate ore-forming temperature of the stratiform ore bodies in this deposit. Sulfur isotope compositions of sulfides are similar to those of VMS-type deposits, reflecting that sulfur originated from the Permian Miaoling Formation. Lead isotope compositions indicate mixed-source for lead. Moreover, the comparison of the Dongfengnanshan stratiform ore bodies with some VMStype deposits in China and abroad, on the trace elements and S–Pb isotope characteristics of the sulfides reveals that the stratiform ore bodies of the Dongfengnanshan deposit belong to the VMS-type, and have closely genetic relationship with the early Permian marine volcanic sedimentary rocks.LU Siyu REN Yunsheng YANG Qun SUN Zhenming HAO Yujie SUN Xinhao 2019Acta Geologica Sinica(English Edition)2019,93,5:3

9Vector tracking loops in GNSS receivers for dynamic weak signals显示文摘Vehicle positioning with the global navigation satellite system(GNSS) in urban environments faces two problems which are attenuation and dynamic.For traditional GNSS receivers hardly able to track dynamic weak signals,the coupling between all visible satellite signals is ignored in the absence of navigation state feedback,and thermal noise error and dynamic stress threshold are contradictory due to non-coherent discriminators.The vector delay/frequency locked loop(VDFLL) with navigation state feedback and the joint vector tracking loop(JVTL) with coherent discriminator which is a synchronization parameter tracking loop based on maximum likelihood estimation(MLE) are proposed to improve the tracking sensitivity of GNSS receiver in dynamic weak signal environments.A joint vector position tracking loop(JVPTL) directly tracking user position and velocity is proposed to further improve tracking sensitivity.The coherent navigation parameter discriminator of JVPTL,being able to ease the contradiction between thermal noise error and dynamic stress threshold,is based on MLE according to the navigation parameter based linear model of received baseband signals.Simulation results show that JVPTL,which combines the advantages of both VDFLL and JVTL,performs better than both VDFLL and JVTL in dynamic weak signal environments.Jing Liu Xiaowei Cui Mingquan Lu Zhenming Feng 2013Journal of Systems Engineering and Electronics2013,24,3:2
10Comparative mitochondrial genome analysis of Varunidae and its phylogenetic implications显示文摘Complete mitochondrial genomes(mitogenomes)can indicate phylogenetic relationships,as well as useful information for gene rearrangement mechanisms and molecular evolution.Currently,the phylogenetic location of the genus Varuna(Brachyura:Varunidae)has not been well resolved mainly because of limited representatives(only two extant species).Here,we determined a new mitogenome of this genus(Varuna litterata)and added the published mitogenomes to reconstruct the phylogeny of Varunidae.The 16368-bp mitogenome contains the entire set of 37 genes and a putative control region.The characteristics of this newly sequenced mitogenome were described and compared with the other 15 Varunidae mitogenomes.All 16 analyzed mitogenomes have identical gene order and similar molecular features.The sliding window and genetic distance analyses demonstrate highly variable nucleotide diversity,with comparatively low variability of COI and COII,and high variability of ND6.The nonsynonymous/synonymous substitution rates(dN/dS ratio)analysis shows that all 13 PCGs are under purifying selection and ATP8 gene evolves under the least selective pressure.Twelve tRNA genes,two rRNAs,one PCG,and the putative control region are found to be rearranged with respect to the pancrustacean ground pattern gene order.Tandem duplication/random loss model is adopted to explain the large-scale gene rearrangement events occurring in Varunidae mitogenomes.Phylogenetic analyses show that all Varunidae species are placed into one group,and form a sister clade with Macrophthalmidae.Nevertheless,the phylogenetic relationships within Varunidae are not completely consistent based on the two different datasets used in this study.These findings will contribute to a better understanding of gene rearrangement and molecular evolution in Varunidae mitogenomes,as well as provide insights into the phylogenetic studies of Brachyura.Ying Zhang Li Gong Xinting Lu Zengliang Miao Lihua Jiang Bingjian Liu Liqin Liu Pengfei Li Xu Zhang Zhenming Lü 2022Acta Oceanologica Sinica2022,41,6:2
