1Overview of the Second Generation AVS Video Coding Standard(AVS2)显示文摘AVS2 is a new generation video coding standard developed by the AVS working group. Compared with the first generation AVS video coding standard, known as AVS1, AVS2 significantly improves coding performance by using many new coding technologies,e.g., adaptive block partition and two level transform coding. Moreover, for scene video, e.g. surveillance video and conference video, AVS2 provided a background picture modeling scheme to achieve more accurate prediction, which can also make object detection and tracking in surveillance video coding more flexible. Experimental results show that AVS2 is competitive with High Efficiency Video Coding(HEVC) in terms of performance. Especially for scene video, AVS2 can achieve 39% bit rate saving over HEVC.Shanshe Wang Falei Luo Siwei Ma 2016ZTE Communications2016,14,1:6
2A computational coding model for saliency detection in primary visual cortex显示文摘This study researches the coding model adaptive for information processing of the bottom-up attention mechanism.We constructed a coding model satisfying the neurobiological constraints of the primary visual cortex.By quantitatively changing the coding constraints,we carried out experiments on images used in cognitive psychology and natural image sets to compare the effects on the saliency detection performance.The experimental results statistically demonstrated that the encoding of invariant features and representation of overcomplete bases is advantageous to the bottom-up attention mechanism.ZOU Qi WANG Zhe LUO SiWei HUANG YaPing TIAN Mei 2012Chinese Science Bulletin2012,57,30:2
3Molecular phylogeny and historical biogeography of the cave fish genus Sinocyclocheilus(Cypriniformes:Cyprinidae)in southwest China显示文摘Modern accumulations of genetic data offer unprecedented opportunities for understanding the systematic classification and origins of specific groups of organisms.The genus Sinocyclocheilus is among the most cave abundant genera in Cyprinidae,with 76 recognized species,belonging to 4 species groups.Recent phylogenetic studies have shown that the classification of species groups within the genus Sinocyclocheilus remains controversial.In this study,we constructed a sequence supermatrix of 26 species from 4 species groups of the genus Sinocyclocheilus using the mitochondrial genome to reveal phylogenetic relationships,historical biogeography and patterns of species diversification in the genus Sinocyclocheilus.Phylogenetic analysis strongly supports the monophyletic groups of the 3 species groups(S.jii,S.cyphotergous,and S.tingi groups)except the S.angularis group.Phylogenetic analysis showed that S.anshuiensis and S.microphthalmus,which were recognized as numbers of S.angularis group,formed a strongly supported independent clade.Therefore,we propose a new species group,the S.microphthalmus group,which contains S.anshuiensis and S.microphthalmus.Biogeographic reconstruction suggests that the living Sinocyclocheilus may have originated in north-central Guangxi at the late Eocene and dispersed outward after a vicariance at 32.31 Million years ago(Ma).Early diversification is focused on the late Oligocene(ca.25 Ma),which is related to the second uplift of the Qinghai−Tibetan Plateau and the lateral extrusion of the Indochina at the Oligocene/Miocene boundary.Our results suggest that 2 uplifts of the Qinghai−Tibetan Plateau and climate change in the Miocene may have influenced the diversification of the Sinocyclocheilus lineage.Huamei WEN Tao LUO Yali WANG Siwei WANG Tao LIU Ning XIAO Jiang ZHOU 2022Integrative Zoology2022,17,2:2
4A New Species of Odorous Frog Genus Odorrana(Anura,Ranidae) from Southern Guizhou Province,China显示文摘We describe Odorrana liboensis sp.nov.,a new species from the Maolan National Nature Reserve,Libo County,Guizhou Province,China.Phylogenetic analyses based on DNA sequences of the mitochondrial 12 S rRNA,16 S rRNA,and ND2 genes supported the new species as an independent lineage,closely related to O.lipuensis.The uncorrected genetic distances between the 12 S rRNA and16 S rRNA in the new species and its closest congener,O.lipuensis,were 6.06%and 5.19%,respectively.The new species is distinguished from its congeners by a combination of the following morphological characters:(1)having medium body size,with the snout-vent length(SVL)of adult females approximately 1.2 times as long as males at 56.9±1.0(55.8-58.2 mm,n=9)in females and 48.7±1.2(47.1-49.9 mm,n=5)in males;(2)head length greater than width in males and females;(3)tympanum distinctly visible,greater than one-half the diameter of the eye;(4)eyes big and prominent,width of upper eyelid(UEW)approximately3/4 of eye diameter(ED);(5)dorsolateral folds absent;(6)two metacarpal tubercles;(7)relative finger lengths:Ⅱ<Ⅰ<Ⅳ<Ⅲ;(8)subarticular tubercles on fingers prominent:1,1,2,2;(9)one metatarsal tubercle;(10)tibiotarsal articulation reaching to between the eye and nostril when the leg is stretched forward;(11)toes with entire webbing to disks;(12)subarticular tubercles on toes prominent:1,1,2,3,2;(13)dorsal surfaces of limbs with distinct brownish-black bands;(14)smooth,grass-green dorsum with irregular brown mottling;(15)venter smooth,lacking black spots;and(16)lacking pectoral spinules,lacking vocal sacs,and light white nuptial pad present on finger I in males.The new species is currently only known from the type locality.Tao LUO Siwei WANG Ning XIAO Yali WANG Jiang ZHOU 2021Asian Herpetological Research2021,12,4:2

10Robust transport of charge carriers in in-plane 1T′-2H MoTe_(2) homojunctions with ohmic contact显示文摘Metal-semiconductor ohmic contacts are required to reduce the energy dissipation for two-dimensional (2D) electronic devices, and phase engineering of 2D transition-metal dichalcogenides (TMDCs) is a promising approach for building ohmic contacts. Here, 2D in-plane 1T′-2H MoTe2 homojunctions were prepared by direct epitaxy via vapor deposition. The interface properties of in-plane 1T′-2H MoTe2 homojunction were investigated in detail by combining experiments, calculations and theories. The ohmic contact properties of 1T′-2H MoTe2 homojunction were proved according to Kelvin force probe microscopy and density functional theory calculations. The charge carriers robust transport in in-plane 1T′-2H MoTe2 homojunction without Fermi-level pinning can be well described by Poisson equation and band alignment. These results indicate that phase engineering of 2D TMDCs is promising to construct ohmic contacts for device applications.Donglin Lu Zhenqing Li Congsheng Xu Siwei Luo Chaoyu He Jun Li Gang Guo Guolin Hao Xiang Qi Jianxin Zhong 2021Nano Research2021,14,5:1

18Preliminary Study on Forest Fire Prevention and Extinguishing in Townships in the Southern Mountainous Areas of Zhejiang Province:A Case Study of Lishui显示文摘Forest fires seriously threaten forestry resources and the life and property safety of people in mountainous areas of Lishui City. In this paper, a fire prevention concept with refined forecast and early warning of forest fire danger weather ratings in townships as the starting point, satellite real-time observation of fire spots, monitoring of the Internet of Things and other high-tech products as an implementation means, and strengthening forest fire prevention equipment and personnel in townships as a guarantee was established. The command system for rapid emergency response by cities, counties and townships should be improved. During the forest fire prevention period, fire sources should be strictly controlled, and the basic principles of forest fire fighting in townships should be implemented into the actual fire prevention and fire fighting work to eliminate forest fires in time at the initial stage and before the disaster.Dalin WANG Ming LUO Xiaobing YANG Siwei ZHENG Jian DENG 2023Meteorological and Environmental Research2023,14,6:0
19Quantitative detection of in vivo physical protein–protein interactions based on DNA sequence recognition显示文摘Dear Editor,Understanding physical protein–protein interactions(PPIs)in vivo is amajor challenge in elucidating the molecular mechanisms in complex biological systems.Although many approaches,such as the yeast two-hybrid(Y2H)assay,protein fragmentcomplementary assay(PCA),and fluorescence resonance energy transfer(FRET)assay,have been developed to assess the intensity of interaction of proteins in living cells,they have practical limitations for quantitation(Morell et al.,2009;Padilla-Parra and Tramier,2012;Stynen et al.,2012).Nucleic acid-based technologies,such as quantitative PCR(qPCR),DNA microarray,and deep sequencing,are probably most featured with quantification,high-throughput,and cost-effective for operation.Recently,new methods of detecting biomolecular interactions have been developed based on a strategy that labels target interactions using specific nucleic acid sequences(Soderberg et al.,2006;Yu et al.,2011;Zhu et al.,2013).Siwei Luo Yihua Jiang Zhi Liang Jiarui Wu 2015Journal of Molecular Cell Biology2015,7,4:0
20Co-recrystallization induced self-catalytic Li2S cathode fully interfaced with sulfide catalyst toward a high-performance lithium-free sulfur battery显示文摘Lithium sulfide(Li_(2)S)is a promising cathode for a practical lithium-sulfur battery as it can be coupled with various safe lithium-free anodes.However,the high activation potential(>3.5 V)together with the shuttling of lithium polysulfides(LiPSs)bottleneck its practical uses.We are trying to present a catalysis solution to solve both problems simultaneously,specially with twinborn heterostructure to shoot off the trouble in interfacial contact between two solids,catalyst and Li_(2)S.As a typical example,a Co9S8/Li_(2)S heterostructure is reported here as a novel self-catalytic cathode through a co-recrystallization followed by a one-step carbothermic conversion.Co9S8 as the catalyst effectively lowers the Li_(2)S activation potential(<2.4 V)due to fully integrated and contacted interfaces and consistently promotes the conversion of LiPSs to suppress the shuttling.The obtained freestanding cathode of Co9S8/Li_(2)S heterostructures encapsulated in three-dimensional graphene shows a high capacity,reaching 92.6%of Li_(2)S theoretical capacity,high rate performance(739 mAh g1 at 2 C),and a low capacity fading(0.039%per cycle at 1 C over 900 cycles).Even under a high Li_(2)S loading of 12 mg cm^(-2)and a low E/S ratio of 5μL mgLi_(2)S^(-1),86%of theoretical capacity can be utilized.Zejian Li Chong Luo Siwei Zhang Guoming Sun Jiabin Ma Xinliang Wang Yan-Bing He Feiyu Kang Quan-Hong Yang Wei Lv 2022InfoMat2022,4,10:0
