| 1 | Image stylization with enhanced structure on GPU显示文摘This paper presents a graphics processing unit (GPU) based stylization approach that preserves the fine structure between the original and the stylized images using gradient optimization.Existing abstraction and painterly stylization methods focused on contrast manipulation only,and thus the detailed salient structures of the input images are always destroyed when performing the current stylization techniques because of limitations like unavoidable salience information loss caused by contrast abstraction.We propose an image structure map to naturally model the fine structure existing in the original images.Gradient-based structure tangent generation and tangent-guided image morphology are used to construct the structure map.The image structure map,unlike an edge map,not only systematically models the boundary information within the imagery but also accentuates the underlying inner structure detail for further stylization.We facilitate the final stylization via parallel bilateral grid and structure-aware stylizing optimization on a GPU-CUDA platform in real time.In multiple experiments,the proposed method consistently demonstrates efficient and high quality image stylization performance. | LI Ping SUN HanQiu SHENG Bin SHEN JianBing | 2012 | Science China(Information Sciences)2012，55，5： | 3 |

| 3 | Cholera Caused by a New Clone of Serogroup O1 Vibrio cholerae-Beijing Municipality,China,June 2021显示文摘Several lineages have been identified in the population of serogroup O1 Vibrio cholerae(V.cholerae)(1-3).The strains,which were responsible for the ongoing seventh cholera pandemic,were in Lineage 2.Nearly all the V.cholerae strains in this lineage carried genes coding cholera toxin(ctxAB)(1-2).Lineage 3b consists of strains isolated from different continents and the vast majority of strains in this lineage lack the ctxAB genes. | Hanqiu Yan Bo Pang Xin Lu Zhiyong Gao Pan Lu Xin Zhang Mengyu Wang Lingyu Shen Wenxuan Zhao Jianhong Zhao Weili Liang Lei Jia Haijian Zhou Zhigang Cui Xiaoli Du Biao Kan Quanyi Wang | 2022 | China CDC weekly2022，4，2： | 3 |
| 4 | Gut health benefit and application of postbiotics in animal production显示文摘Gut homeostasis is of importance to host health and imbalance of the gut usually leads to disorders or diseases for both human and animal.Postbiotics have been applied in manipulating of gut health,and utilization of postbiotics threads new lights into the host health.Compared with the application of probiotics,the characteristics such as stability and safety of postbiotics make it a potential alternative to probiotics.Studies have reported the beneficial effects of components derived from postbiotics,mainly through the mechanisms including inhibition of pathogens,strengthen gut barrier,and/or regulation of immunity of the host.In this review,we summarized the characteristics of postbiotics,main compounds of postbiotics,potential mechanisms in gut health,and their application in animal production. | Yifan Zhong Shanshan Wang Hanqiu Di Zhaoxi Deng Jianxin Liu Haifeng Wang | 2022 | Journal of Animal Science and Biotechnology2022，13，4： | 3 |
| 5 | Vibrio parahaemolyticus O10:K4:An Emergent Serotype with Pandemic Virulence Traits as Predominant Clone Detected by Whole-Genome Sequence Analysis--Beijing Municipality,China,2021显示文摘Introduction:Vibrio parahaemolyticus(V.parahaemolyticus)is a common foodborne pathogen which causes gastroenteritis in humans,especially the O3:K6 pandemic clone which is still a prominent serotype in Beijing,China.In this study,we observed a novel serotype O10:K4 isolated from clinical diarrhea cases,which became the most prevalent clone in 2021.Methods:73 clinical isolates were collected through sentinel hospitals’surveillance in 2021.Serum agglutination testing and antimicrobial susceptibility testing were conducted.Whole genome sequencing was applied to characterize 73 V.parahaemolyticus strains and complete phylogenetic analysis.Results:Seven serotypes were identified among 73 strains.O10:K4 was the most common serotype(83.6%),followed by O2:KUT,O4:KUT,and O1:KUT.Multilocus sequence typing divided the 73 isolates into 10 sequence types(STs)with ST3 as the most prevalent,which covered all O10:K4 strains.Most isolates were sensitive to common antimicrobial agents apart from colistin.All the O10:K4 isolates were positive for the thermostable direct hemolysin gene,toxRS/new,and orf8,and negative for the TDH-related hemolysin gene.The whole genome sequencing-single nucleotide polymorphism phylogenetic analysis revealed O10:K4 strains formed a main genetic lineage,which was genetically distinct from other serotypes.We also demonstrated the presence of two type III secretion system genes(T3SS1 and T3SS2)andβlactamase resistance gene blaCARB-22 in all O10:K4 strains.Conclusions:The study confirmed the emergence of V.parahaemolyticus O10:K4 possessing virulence factors similar to the O3:K6 pandemic clone,which may have enabled them to become prevalent in Beijing,China. | Ying Huang Bing Lyu Xin Zhang Yi Tian Changying Lin Lingyu Shen Hanqiu Yan Daitao Zhang Lei Jia Mei Qu Quanyi Wang | 2022 | China CDC weekly2022，4，22： | 2 |
