| 1 | Wind tunnel study of aerodynamic wind loading on middle pylon of Taizhou Bridge显示文摘Segment sectional model tests are carried out to investigate the wind loading on middle pylon of Taizhou Bridge, which has complicated three-dimensional flow due to its feature of double columns. Through the force measuring tests, aerodynamic force coefficients of every segment of the pylon columns have been obtained. It is found that the tested aerodynamic force coefficients are much smaller than those given by codes. The interference effects of aerodynamic force coefficients between columns of pylon are discussed. The results show that the interference effect is the most evident when the yaw angle is about 30 ° from transverse direction. This kind of interference effect can be described as diminutions in transverse aerodynamic force coefficients and magnifications in longitudinal aerodynamic force coefficients of downstream columns. | Zhang Zhen Ma Rujin Hu Xiaohong Chen Airong | 2011 | Engineering Sciences2011，9，2： | 1 |

| 5 | Dgcr8 deletion in the primitive heart uncovered novel microRNA regulating the balance of cardiac-vascular gene program显示文摘Primitive mammalian heart transforms from a single tube to a four-chambered muscular organ during a short developmental window.We found that knocking out global microRNA by deleting Dgcr8 microprocessor in Mespl cardiovascular progenitor cells lead to the formation of extremely dilated and enlarged heart due to defective cardiomyocyte(CM)differentiation.Transcriptome analysis revealed unusual upregulation of vascular gene expression in Dgcr8 cKO hearts.Single cell RNA sequencing study further confirmed the increase of angiogenesis genes in single Dgcr8 cKO CM.We also performed global microRNA profiling of E9.5 heart for the first time,and identified that miR-541 was transiently highly expressed in E9.5 hearts.Interestingly,introducing miR-541 back into microRNA-free CMs partially rescued their defects,downregulated angiogenesis genes and significantly upregulated cardiac genes.Moreover,miR-541 can target Ctgf and inhibit endothelial function.Our results suggest that micro-RNAs are required to suppress abnormal angiogenesis gene program to maintain CM differentiation. | Xi Chen Lin Wang Rujin Huang Hui Qiu Peizhe Wang Daren Wu Yonglin Zhu Jia Ming Yangming Wang Jianbin Wang Jie Na | 2019 | Protein & Cell2019，10，5： | 1 |

| 7 | Aerodynamic problems of cable-stayed bridges spanning over one thousand meters显示文摘The elongating of cable-stayed bridge brings a series of aerodynamic problems. First of all,geometric nonlinear effect of extreme long cable is much more significant for cable-stayed bridge spanning over one thousand meters. Lateral static wind load will generate additional displacement of long cables,which causes the decrease of supporting rigidity of the whole bridge and the change of dynamic properties. Wind load,being the controlling load in the design of cable-stayed bridge,is a critical problem and needs to be solved. Meanwhile,research on suitable system between pylon and deck indicates fixed-fixed connection system is an effective way for improvement performance of cable-stayed bridges under longitudinal wind load. In order to obtain aerodynamic parameters of cable-stayed bridge spanning over one thousand meters,identification method for flutter derivatives of full bridge aero-elastic model is developed in this paper. Furthermore,vortex induced vibration and Reynolds number effect are detailed discussed. | Chen Airong Ma Rujin Wang Dalei | 2009 | Engineering Sciences2009，7，3： | 1 |

| 9 | A long non-coding RNA LncSync regulates mouse cardiomyocyte homeostasis and cardiac hypertrophy through coordination of miRNA actions显示文摘Dear Editor,Maintenance of cardiomyocyte(CM)homeostasis is essential for normal heart function.Long-term imbalance in heart homeostasis could elicit irreversible adaptive change in cell structure and function and tissue architecture,exemplified as cardiac hyper-trophy and fibrosis,and eventually develop into heart failure(Shiojima et al.,2005).Therefore,identifying new genes and path-ways regulating CM homeostasis may help better understand the cause of cardiac hypertrophy. | Rujin Huang Jinyang Liu Xi Chen Ying Zhi Shuangyuan Ding Jia Ming Yulin Li Yangming Wang Jie Na | 2023 | Protein & Cell2023，14，2： | 0 |
| 10 | Moderate Resolution Imaging Camera (MoRIC) of China’s First Mars Mission Tianwen-1显示文摘China's first Mars exploration mission will carry out comprehensive global surveys of the planet from data collected by instruments carried in orbit and roving on the planet itself.Goals of the mission include detailed inspections and surveys of key areas on the surface of Mars.One of the main scientific payloads installed on the orbiter is the moderate resolution camera.Its mission is to image the surface of Mars sufficiently to produce a global remote sensing image map of the planet,and to explore and record changes to the topography of Mars,including major geological structures,and to advance research on topography and geomorphology in general.The moderate resolution camera uses a lightweight and compact integrated design;its primary components are an optical module,a focal plane module,a camera control module,a power and interface module,a camera support module,a thermal control module,and a reference module.Radiometric calibration,color calibration,and geometric calibration have been carried out to ensure that the camera can acquire sufficient accurate data to complete mission goals.This paper introduces the camera's detection mission,its system composition,and its working principle;it also describes the camera's ground calibration tests and their results,and provides a reference for processing the camera's scientific data and for future applications. | GuoBin Yu EnHai Liu GuangLin Liu Li Zhou JunZhe Zeng YuanPei Chen XiangDong Zhou RuJin Zhao ShunYi Zhu | 2020 | Earth and Planetary Physics2020，4，4： | 0 |
| 11 | Wind tunnel study on wind-induced vibration of middle pylon of Taizhou Bridge显示文摘Full aero-elastic model tests are carried out to investigate wind-induced vibration of middle steel pylon of Taizhou Bridge. Model of the pylon under different construction periods is tested in both uniform and turbulent flow field. And the yaw angle of wind changes from transverse to longitudinal. Through full aero-elastic model testing, wind-induced vibration is checked, which includes vortex resonance, buffeting and galloping. Vortex resonance is observed and further studies are carried out by changing damping ratio. Based on wind tunnel testing results, wind-resistance of middle pylon is evaluated and some suggestions are given for middle pylon's construction. | Ma Rujin Zhang Zhen Chen Airong | 2012 | Engineering Sciences2012，10，3： | 0 |
