| 1 | Simulation of Moon-based Earth observation optical image processing methods for global change study显示文摘Global change affected by multiple factors,the consequences of which continue to be far-reaching,has the characteristics of large spatial scale and long-time scale.The demand for Earth observation technology has been increasing for large-scale simultaneoiis observations and stable global observation over the long-term.A Moon-based observation platform,which uses sensors on the nearside lunar surface,is considered a reasonable solution.However,owing to a lack of appropriate processing methods for optical sensor data,global change study using this platform is not sufficient.This paper proposes two optical sensor imaging processing methods for the Moon-based platform:area imaging processing method(AIPM)and global imaging processing method(GIPM),primarily considering global change characteristics,optical sensor performance,and motion law of the Moon-based platform.First,the study proposes a simulation theory which includes the construction of a Moon-Sun elevation angle model and a global image mosaicking method.Then,coverage images of both image processing methods are simulated,and their features are quantitatively analyzed.Finally,potential applications are discussed.Results show that AEPM,whose coverage is mainly affected by lunar revolution,is approximately between 0%and 50%with a period of 29.5 days,which can help the study of large-scale instant change phenomena.GIPM,whose coverage is affected by Earth revolution,is conducive to the study of long term global-scale phenomena because of its sustained stable observation from 67°N-67°S on the Earth.AIPM and GIPM have great advantages in Earth observation of tripolar regions.The existence of top of the atmosphere(TOA)albedo balance line is verified from the GIPM perspective.These two imaging methods play a significant role in linking observations acquired from the Moon-based platform to Earth large-scale geoscience phenomena,and thus lay a foundation for using this platform to capture global environmental changes and new discoveries. | Tong LI Huadong GUO Li ZHANG Chenwei NIE Jingjuan LIAO Guang LIU | 2020 | Frontiers of Earth Science2020，14，1： | 2 |

| 5 | Causal relationship between inflammatory bowel disease and gingivitis or periodontal disease:A two-sample Mendelian randomized analysis显示文摘Background:Observational studies have shown that inflammatory bowel disease(IBD),such as ulcerative colitis(UC)and Crohn disease(CD),is associated with gingivitis and periodontal disease(GP).This study aims to investigate whether there is a causal relationship between IBD and GP.Methods:This study assessed the causal relationship between IBD and GP through a two-sample Mendelian randomization(MR)study.The required data were obtained through the IEU OpenGWAS project.Instrumental variable screening and the MR and sensitivity analyses were performed using the“TwoSampleMR”R package.Results:IBD,UC,and CD may have a causal effect on GP(IBD,inverse variance weighting[IVW]OR=1.05,95%CI=1.00–1.10,P=0.03;UC,IVWOR=1.05,95%CI=1.00–1.11,P=0.03;CD,weighted median OR=1.06,95%CI=1.00–1.13,P=0.04;simple mode OR=1.15,95%CI=1.02–1.31,P=0.03).Scatterplots,forest plots,and funnel plots showed a significant relationship between IBD and GP and confirmed the robustness of the model.In sensitivity testing,no horizontal pleiotropy or heterogeneity was found in this study.Conclusions:This study found a possible causal relationship between IBD(UC and CD)and GP,which deserves to be considered in clinical practice. | Yi-Chao Ma Wen-Qi Li ChenWei Fei Wang Yi-Qun Liao Bin Zhao Yu-Ji Chen Qi Zhao Jie Qiu Dong Tang | 2023 | Journal of Nutritional Oncology2023，8，2： | 0 |
