| 2 | Science with the 2.5-meter Wide Field Survey Telescope(WFST)显示文摘The Wide Field Survey Telescope(WFST) is a dedicated photometric surveying facility being built jointly by University of Science and Technology of China(USTC) and the Purple Mountain Observatory(PMO). It is equipped with a 2.5-meter diameter primary mirror, an active optics system, and a mosaic CCD camera with 0.73 gigapixels on the primary focal plane for highquality image capture over a 6.5-square-degree field of view. The installation of WFST near the summit of Saishiteng mountain in the Lenghu region is scheduled in summer of 2023, and the operation is planned to start three months later. WFST will scan the northern sky in four optical bands(u, g, r and i) at cadences from hourly/daily in the deep high-cadence survey(DHS) program, to semi-weekly in the wide field survey(WFS) program. During a photometric night, a nominal 30 s exposure in the WFS program will reach a depth of 22.27, 23.32, 22.84, and 22.31(AB magnitudes) in these four bands, respectively, allowing for the detection of a tremendous amount of transients in the low-z universe and a systematic investigation of the variability of Galactic and extragalactic objects. In the DHS program, intranight 90 s exposures as deep as 23(u) and 24 mag(g), in combination with target of opportunity follow-ups, will provide a unique opportunity to explore energetic transients in demand for high sensitivities, including the electromagnetic counterparts of gravitational wave events, supernovae within a few hours of their explosions,tidal disruption events and fast, luminous optical transients even beyond redshift of unity. In addition, the final 6-year co-added images, anticipated to reach g■25.8 mag in WFS or 1.5 mags deeper in DHS, will be of fundamental importance to general Galactic and extragalactic science. The highly uniform legacy surveys of WFST will serve as an indispensable complement to those of the Vera C. Rubin Observatory's Legacy Survey of Space and Time(LSST) that monitors the southern sky. | Tinggui Wang Guilin Liu Zhenyi Cai Jinjun Geng Min Fang Haoning He Ji-an Jiang Ning Jiang Xu Kong Bin Li Ye Li Wentao Luo Zhizheng Pan Xuefeng Wu Ji Yang Jiming Yu Xianzhong Zheng Qingfeng Zhu Yi-Fu Cai Yuanyuan Chen Zhiwei Chen Zigao Dai Lulu Fan Yizhong Fan Wenjuan Fang Zhicheng He Lei Hu Maokai Hu Zhiping Jin Zhibo Jiang Guoliang Li Fan Li Xuzhi Li Runduo Liang Zheyu Lin Qingzhong Liu Wenhao Liu Zhengyan Liu Wei Liu Yao Liu Zheng Lou Han Qu Zhenfeng Sheng Jianchun Shi Yiping Shu Zhenbo Su Tianrui Sun Hongchi Wang Huiyuan Wang Jian Wang Junxian Wang Daming Wei Junjie Wei Yongquan Xue Jingzhi Yan Chao Yang Ye Yuan Yefei Yuan Hongxin Zhang Miaomiao Zhang Haibin Zhao Wen Zhao | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，10： | 1 |
| 3 | Yes-associated protein contributes to magnesium alloy-derivedinflammation in endothelial cells显示文摘Magnesium alloy(Mg alloy)has attracted massive attention in the potential applications of cardiovascular stents because of its good biocompatibility and degradability.However,whether and how the Mg alloy induces inflammation in endothelial cells remains unclear.In the present work,we investigated the activation of Yes-associated protein(YAP)upon Mg alloy stimuli and unveiled the transcriptional function in Mg alloy-induced inflammation.Quantitative RT–PCR,western blotting and immunofluorescence staining showed that Mg alloy inhibited the Hippo pathway to facilitate nuclear shuttling and activation of YAP in human coronary artery endothelial cells(HCAECs).Chromatin immunoprecipitation followed sequencing was carried out to explore the transcriptional function of YAP in Mg alloy-derived inflammation.This led to the observation that nuclear YAP further bonded to the promoter region of inflammation transcription factors and co-transcription factors.This binding event activated their transcription and modified mRNA methylation of inflammation-related genes through regulating the expression of N6-methyladenosine modulators(METTL3,METTL14,FTO and WTAP).This then promoted inflammation-related gene expression and aggravated inflammation in HCAECs.In YAP deficiency cells,Mg alloy-induced inflammation was reduced.Collectively,our data suggest that YAP contributes to the Mg alloy-derived inflammation in HCAECs and may provide a potential therapeutic target that alleviates inflammation after Mg alloy stent implantation. | Hongchi Yu Zhe Hou Nuoya Chen Rifang Luo Li Yang Michael Miao Xiaoyi Ma Lifeng Zhou Fugui He Yang Shen Xiaoheng Liu Yunbing Wang | 2022 | Regenerative Biomaterials2022，9，1： | 0 |
| 4 | The biological responses and mechanisms of endothelial cells to magnesium alloy显示文摘Due to its good biocompatibility and degradability,magnesium alloy(Mg alloy)has shown great promise in cardiovascular stent applications.Rapid stent re-endothelialization is derived from migrated and adhered endothelial cells(ECs),which is an effective way to reduce late thrombosis and inhibit hyperplasia.However,fundamental questions regarding Mg alloy affecting migration and adhesion of ECs are not fully understood.Here,we evaluated the effects of Mg alloy on the ECs proliferation,adhesion and migration.A global gene expression profiling of ECs co-culturing with Mg alloy was conducted,and the adhesion-and migration-related genes were examined.We found that Mg alloy had no adverse effects on ECs viability but significantly affected ECs migration and adhesion.Co-cultured with Mg alloy extract,ECs showed contractive adhesion morphology and decreased motility,which was supported by the down-regulation of adhesion-related genes(Paxillin and Vinculin)and migration-related genes(RAC 1,Rho A and CDC 42).Accordingly,the re-endothelialization of Mg alloy stent was inhibited in vivo.Our results may provide new inspiration for improving the broad application of Mg alloy stents. | Zhe Hou Maolong Xiang Nuoya Chen Xiao Cai Bo Zhang Rifang Luo Li Yang Xiaoyi Ma Lifeng Zhou Fugui He Hongchi Yu Yunbing Wang | 2021 | Regenerative Biomaterials2021，8，3： | 0 |
| 5 | Mathematical Modeling and Design of RIS Deployment in a RIS-Assisted Metal Cuboid for WAIC Systems显示文摘Wireless avionics intra-communications(WAIC)is an emergent research topic,since it can improve fuel efficiency and enhance aircraft safety significantly.However,there are numerous baffles in an aircraft,e.g.,seats and cabin bulkheads,resulting in serious blockage and even destroying wireless communications.Thus,this paper focuses on the reconfigurable intelligent surface(RIS)deployment issue of RIS-assisted WAIC systems,to solve the blockage problem caused by baffles.We first propose the mirror-symmetric imaging principle for mathematically analyzing electromagnetic(EM)wave propagation in a metal cuboid,which is a typical structure of WAIC systems.Based on the mirror-symmetric imaging principle,the mathematical channel model in a metal cuboid is deduced in detail.In addition,we develop an objective function of RIS's location and deduce the optimal RIS deployment location based on the geometric center optimization lemma.A two-dimensional gravity center search algorithm is then presented.Simulation results show that the designed RIS deployment can greatly increase the received power and efficiently solve the blockage problem in the aircraft. | Hongchi Lin Qiyue Yu | 2023 | China Communications2023，20，4： | 0 |
