| 1 | Recombinant protein subunit vaccine booster following two-dose inactivated vaccines dramatically enhanced anti-RBD responses and neutralizing titers against SARS-CoV-2 and Variants of Concern显示文摘Dear Editor,As of October,2021,SARS-CoV-2 has infected more than 230 million people;promoting roll-out vaccinations could help build herd immunity for the pandemic.However,the waning of antibody in magnitude and decreased protective efficacy in multiple types of vaccines have been reported. | Jingwen Ai Haocheng Zhang Qiran Zhang Yi Zhang Ke Lin Zhangfan Fu Jieyu Song Yuanhan Zhao Mingxiang Fan Hongyu Wang Chao Qiu Yang Zhou Wenhong Zhang | 2022 | Cell Research2022，32，1： | 19 |
| 2 | Detecting visually salient scene areas and deriving their relative spatial relations from continuous street-view panoramas显示文摘A salient scene is an area within an image that contains visual elements that stand out from surrounding areas.They are important for distinguishing landmarks in first-person-view(FPV)applications and determining spatial relations in images.The relative spatial relation between salient scenes acts as a visual guide that is easily accepted and understood by users in FPV applications.However,current digitally navigable maps and location-based services fall short of providing information on visual spatial relations for users.This shortcoming has a critical influence on the popularity and innovation of FPV applications.This paper addresses the issue by proposing a method for detecting visually salient scene areas(SSAs)and deriving their relative spatial relationships from continuous panoramas.This method includes three critical steps.First,an SSA detection approach is introduced by fusing region-based saliency derived from super-pixel segmentation and the frequency-tuned saliency model.The method focuses on a segmented landmark area in a panorama.Secondly,a street-view-oriented SSA generation method is introduced by matching and merging the visual SSAs from continuous panoramas.Thirdly,a continuous geotagged panorama-based referencing approach is introduced to derive the relative spatial relationships of SSAs from continuous panoramas.This information includes the relative azimuth,elevation angle,and the relative distance.Experiment results show that the error for the SSA relative azimuth angle is approximately±6°(with an average error of 2.67°),and the SSA relative elevation angle is approximately±4°(with an average error of 1.32°)when using Baidu street-view panoramas.These results demonstrate the feasibility of the proposed approach.The method proposed in this study can facilitate the development of FPV applications such as augmented reality(AR)and pedestrian navigation using proper spatial relation. | Fangli Guan Zhixiang Fang Tao Yu Mingxiang Feng Fan Yang | 2020 | International Journal of Digital Earth2020，13，12： | 2 |

| 4 | Two-dimensional Stiefel-Whitney insulators in liganded Xenes显示文摘Two-dimensional(2D)Stiefel-Whitney insulator(SWI),which is characterized by the second Stiefel-Whitney class,is a class of topological phases with zero Berry curvature.As an intriguing topological state,it has been well studied in theory but seldom realized in realistic materials.Here we propose that a large class of liganded Xenes,i.e.,hydrogenated and halogenated 2D group-IV honeycomb lattices,are 2D SWIs.The nontrivial topology of liganded Xenes is identified by the bulk topological invariant and the existence of protected corner states.Moreover,the large and tunable bandgap(up to 3.5 eV)of liganded Xenes will facilitate the experimental characterization of the 2D SWI phase.Our findings not only provide abundant realistic material candidates that are experimentally feasible but also draw more fundamental research interest towards the topological physics associated with Stiefel-Whitney class in the absence of Berry curvature. | Mingxiang Pan Dexin Li Jiahao Fan Huaqing Huang | 2022 | npj Computational Materials2022，，1： | 0 |
| 5 | Ground glass nodules with scattered or eccentric island-shaped consolidations may have poor outcomes显示文摘Background:To explore the effect of scattered or eccentric shaped types of ground glass opacity(GGO)on outcomes of patients with solid-dominant peripheral lung adenocarcinoma.Methods:We evaluated patients with solid-dominant peripheral lung adenocarcinoma,who underwent radical surgery at Zhongshan Hospital,Fudan University,between January 2013 and December 2015.Morphologically heterogeneous solid-dominant lung adenocarcinoma in imaging findings was based on the last preoperative computed tomography(CT)scans.Endpoints were recurrence-free survival(RFS)and overall survival(OS).Kaplan-Meier analysis and the log-rank test were used to estimate survival differences.Impact factors were assessed by univariable logistic regression analysis.Results:We retrospectively collected data from 200 patients,including 170 patients with central island-shaped CT imaging,18 patients with scattered shaped CT imaging,and 12 patients with eccentric shaped CT imaging.Eleven patients experienced recurrence or metastases.Kaplan-Meier survival curves showed significant survival differences between the central island-shaped type and scattered shaped or eccentric shaped type for OS(c-stage IA:5-year OS:100%vs.92.1%;HR=0.019,p=0.0025;p-stage IA:100%vs.95.2%;HR=0.146,p=0.1139)and RFS(c-stage IA:5-year RFS:100%vs.59.7%;HR=0.001,p<0.0001;p-stage IA:100%vs.64.5%;HR<0.001,p<0.0001).Univariable logistic regression analysis showed that scattered and eccentric shaped types were related to poor outcomes(p<0.012,odds ratio=18.8)。Conclusions:Relative spatial position of GGO and solid components may affect patient outcomes.Patients with scattered or eccentric shaped GGO may have a poor prognosis. | Ming Li Junjie Xi Huan Zhang Xing Jin Zhuoyang Fan Cheng Zhan Mingxiang Feng Lijie Tan Qun Wang | 2023 | Cancer Innovation2023，2，2： | 0 |
| 6 | Space Materials Science in China:Ⅱ.Ground-based Researches and Academic Activities显示文摘Activities of space materials science research in China have been continuously supported by two main national programs.One is the China Space Station(CSS)program since 1992,and the other is the Strategic Priority Program(SPP)on Space Science since 2011.In CSS plan in 2019,eleven space materials science experimental projects were officially approved for execution during the construction of the space station.In the SPP Phase Ⅱ launched in 2018,seven pre-research projects are deployed as the first batch in 2018,and one concept study project in 2019.These pre-research projects will be cultivated as candidates for future selection as space experiment projects on the recovery of scientific experimental satellites in the future.A new apparatus of electrostatic levitation system for ground-based research of space materials science and rapid solidification research has been developed under the support of the National Natural Science Foundation of China.In order to promote domestic academic activities and to enhance the advancement of space materials science in China,the Space Materials Science and Technology Division belong to the Chinese Materials Research Society was established in 2019.We also organized scientists to write five review papers on space materials science as a special topic published in the journal Scientia Sinica to provide valuable scientific and technical references for Chinese researchers. | PAN Mingxiang WANG Weihua FAN Shuqian ZHANG Qi PAN Xiuhong DENG Weijie HU Liang WEI Bingbo WANG Haipeng YIN Zhigang FANG Jinghong YU Jianding ZHANG Xingwang YUAN Zhangfu JIANG Hongxiang ZHAO Jiuzhou WANG Gong | 2020 | 空间科学学报2020，40，5： | 0 |
