| 1 | Wind tunnel measurement of aerodynamic characteristics of trains passing each other on a simply supported box girder bridge显示文摘The aerodynamic performance of high-speed trains passing each other was investigated on a simply supported box girder bridge,with a span of 32 m,under crosswinds.The bridge and train models,modeled at a geometric scale ratio of 1:30,were used to test the aerodynamic forces of the train,with the help of a designed moving test rig in the XNJD-3 wind tunnel.The effects of wind speed,train speed,and yaw angle on the aerodynamic coefficients of the train were analyzed.The static and moving model tests were compared to demonstrate how the movement of the train influences its aerodynamic characteristics.The results show that the sheltering effect introduced by trains passing each other can cause a sudden change in force on the leeward train,which is further influenced by the wind and running speeds.Detailed analyses related to the effect of wind and train speeds on the aerodynamic coefficients were conducted.The relationship between the change in aerodynamic coefficients and yaw angle was finally described by a series of proposed fitting formulas. | Xiaozhen Li Yiling Tan Xiaowei Qiu Zhenhua Gong Ming Wang | 2021 | Railway Engineering Science2021，29，2： | 5 |

| 3 | Developmental validation of the novel six-dye Goldeneye^(TM)DNA ID System 35InDel kit for forensic application显示文摘Insertion/deletion polymorphisms(InDels)have been treated as a prospective and helpful genetic marker in the fields of forensic human identification,anthropology and population genetics for the past few years.In this study,we developed a six-dye multiplex typing system consisting of 34 autosomal InDels and Amelogenin for forensic application.The contained InDels were specifically selected for Chinese population with the MAF≥0.25 in East Asia,which do not overlap with the markers of Investigator^(■)DIPplex kit.The typing system was named as GoldeneyeTM DNA ID System 35InDel Kit,and a series of developmental validation studies including repeatability/reproducibility,concordance,accuracy,sensitivity,stability,species specificity and population genetics were conducted on this kit.We confirmed that the 35InDel kit is precise,sensitive,species specific and robust for forensic practice.Moreover,the 35InDel kit is capable of typing DNA extracted from forensic routine case-type samples as well as degraded samples and mixture samples.All markers are proved to be highly polymorphic with an average observed heterozygosity(He)of 0.4582.The combined power of discrimination(CPD)is 0.999999999999978 and the combined power of exclusion in duos(CPE_(D))and trios(CPE_(T))are 0.978837 and 0.999573,respectively,which are higher than those of the Investigator^(■)DIPplex kit.Thus,the GoldeneyeTM DNA ID System 35InDel kit is suitable for forensic human identification and could serve as a supplementary typing system for paternity testing. | Qi Yang Huan Yu Yiling Qu Xiaochun Zhang Ruocheng Xia Ziwei Wang Rui Tan Lei Xiong Shihan Xi Jun Wu Yuzhen Gao Suhua Zhang Chengtao Li | 2022 | Forensic Sciences Research2022，7，4： | 0 |
| 4 | Regulatory variation within 3’UTR of STAT5A correlates with sudden cardiac death in Chinese populations显示文摘Definitive diagnosis to sudden cardiac death(SCD)is often challenging since the postmortem examination on SCD victims could hardly demonstrate an adequate cause of death.It is therefore important to uncover the inherited risk component to SCD.Signal transducer and activators of transcription 5 A(STAT5A)is a member of the STAT family and a transcription factor that is activated by many cell ligands and associated with various cardiovascular processes.In this study,we performed a systematic variant screening on the STAT5A to filter potential functional genetic variations.Based on the screening results,an insertion/deletion polymorphism(rs3833144)in 3’UTR of STAT5A was selected as the candidate variant.A total of 159 SCD cases and 668 SCD matched healthy controls was enrolled to perform a case-control study and evaluate the association between rs3833144 and SCD susceptibility in Chinese populations.Logistic regression analysis showed that the deletion allele of rs3833144 had significantly increased the SCD risk(odds ratio(OR)=1.54;95%confidence interval(CI)=1.18-2.01;P=0.000955).Further genotype-expression eQTL analysis showed that samples with deletion allele appeared to lower expression of STAT5A,and in silico prediction suggested the local 3 D structure changes of STAT5A mRNA caused by the variant.On the other hand,the bioinformatic analysis presented that promoters of RARA and PTGES3L-AARSD1 could interact with rs3833144,and eQTL analysis showed the higher expression of both genes in samples with deletion allele.Dual-luciferase activity assays also suggested the significant regulatory role of rs3833144 in gene transcription.Our current data thus suggested a possible involvement of rs3833144 to SCD predisposition in Chinese populations and rs3833144 with potential function roles may become a candidate marker for SCD diagnosis and prevention. | Huan Yu Yadong Guo Zhenzhen Yang Qing Zhang Jiabin Xu Qi Yang Yiling Qu Rui Tan Lijuan Li Yan He Chengtao Li Suhua Zhang Bin Luo Yuzhen Gao | 2022 | Forensic Sciences Research2022，7，4： | 0 |
| 5 | The roles of phosphate in shaping the structure and dynamics of Antarctic soil microbiomes显示文摘One major consequence of global warming in the Antarctic region is increased ice-free zones.Subsequent colonization of these ice-free areas by penguins alters their biogeochemistry,with one prominent example being elevation of inorganic phosphate concentrations around feces depositions.The complex soil biochemistry in the region makes it difficult to define the causal factors of these changes using common research approaches.Here,we addressed the effects of phosphate alone on microbiome structure and dynamics over time by adding external phosphate to selected soils in the Antarctic region.We then analyzed the soil bacterial community composition and diversity using 16S rRNA amplicon sequencing and compared these data with phosphate levels.Parallel geochemical analysis revealed changes in nine soil geochemical factors upon phosphate addition,all of which were relevant to microbiome structure,with soil pH showing the highest correlation.Links between geochemical factors and composition were identified,as were interactions between bacterial taxa.Additionally,Sphingobacteriia,Sphingobacteriales and Chitinophagaceae were found to be more abundant in phosphate-treated soils.Co-occurrence network analysis revealed significantly increased levels of associations in all major network properties over time after phosphate supplementation.Therefore,we conclude phosphate addition has diverse effects on Antarctic soil microbiomes. | TAN Jiankang CAO Huansheng LIU Li QIN Yiling LIU Feng John CAVA YIN Xiaofei SHEN Jihong WANG Nengfei | 2023 | Advances in Polar Science2023，34，1： | 0 |

| 8 | What can we learn from quality assurance badges in open-source software?显示文摘In the development of open-source software(OSS),many developers use badges to give an overview of the software and share some key features/metrics conveniently.Among various badges,quality assurance(QA)badges make up a large proportion and are the most prevalent because QA is of vital importance in software development,and ineffective QA may lead to anomalies or defects.In this paper,we focus on QA badges in open-source projects,which present quality assurance information directly and instantly,and aim to produce some interesting findings and provide practical implications.We collect and analyze 100000 projects written in popular programming languages from GitHub and conduct a comprehensive empirical study both inside and outside QA badges.Inside QA badges,we build a category classification for all QA badges based on the properties they focus on,which shows the types of QA badges developers use.Then,we analyze the frequency of the properties that QA badges focus on,and property combinations,too,which present their use status.We find that QA badges focus on various properties while developers give different preferences to different properties.The use status also differs between different programming languages.For example,projects written in C focus on Security to a great extent.Our findings also provide implications for developers and badge providers.Outside QA badges,we conduct a correlation analysis between QA badges and some software metrics that have potential relationships with code quality,contribution quality,and popularity.We find that QA badges have statistically significant correlations with various software metrics. | Feng LI Yiling LOU Xin TAN Zhenpeng CHEN Jinhao DONG Yang LI Xuanzhi WANG Dan HAO Lu ZHANG | 2024 | Science China(Information Sciences)2024，67，4： | 0 |
