| 1 | Landslide susceptibility prediction using slope unit-based machine learning models considering the heterogeneity of conditioning factors显示文摘To perform landslide susceptibility prediction(LSP),it is important to select appropriate mapping unit and landslide-related conditioning factors.The efficient and automatic multi-scale segmentation(MSS)method proposed by the authors promotes the application of slope units.However,LSP modeling based on these slope units has not been performed.Moreover,the heterogeneity of conditioning factors in slope units is neglected,leading to incomplete input variables of LSP modeling.In this study,the slope units extracted by the MSS method are used to construct LSP modeling,and the heterogeneity of conditioning factors is represented by the internal variations of conditioning factors within slope unit using the descriptive statistics features of mean,standard deviation and range.Thus,slope units-based machine learning models considering internal variations of conditioning factors(variant slope-machine learning)are proposed.The Chongyi County is selected as the case study and is divided into 53,055 slope units.Fifteen original slope unit-based conditioning factors are expanded to 38 slope unit-based conditioning factors through considering their internal variations.Random forest(RF)and multi-layer perceptron(MLP)machine learning models are used to construct variant Slope-RF and Slope-MLP models.Meanwhile,the Slope-RF and Slope-MLP models without considering the internal variations of conditioning factors,and conventional grid units-based machine learning(Grid-RF and MLP)models are built for comparisons through the LSP performance assessments.Results show that the variant Slopemachine learning models have higher LSP performances than Slope-machine learning models;LSP results of variant Slope-machine learning models have stronger directivity and practical application than Grid-machine learning models.It is concluded that slope units extracted by MSS method can be appropriate for LSP modeling,and the heterogeneity of conditioning factors within slope units can more comprehensively reflect the relationships between conditioning factors and landslides.The research results have important reference significance for land use and landslide prevention. | Zhilu Chang Filippo Catani Faming Huang Gengzhe Liu Sansar Raj Meena Jinsong Huang Chuangbing Zhou | 2023 | Journal of Rock Mechanics and Geotechnical Engineering2023，15，5： | 2 |

| 5 | An updating of landslide susceptibility prediction from the perspective of space and time显示文摘Due to the similarity of conditioning factors,the aggregation feature of landslides and the multi-temporal landslide inventory,the spatial and temporal effects of landslides need to be considered in landslide susceptibility prediction(LSP).The ignorance of this issue will result in some biases and time-invariance in landslide susceptibility.Hence,a novel framework has been proposed to update landslide susceptibility by simultaneously considering the spatial and temporal effects of landslides at the regional scale.In this framework,the landslide inventory of Chongyi County has been divided into pre-and fresh-landslide inventories.According to the LSP results predicted by the support vector machine(SVM)model using the slope unit-based conditioning factors and pre-landslide inventory,a normalized spatial distance index(NSDI)is calculated to quantitatively represent the spatial correlation between landslides and surrounding slope units to develop the SVM-NSDI model.Furthermore,the SVM-Updating model,which incorporates the LSP results of the SVM-NSDI model and fresh-landslide inventory,could be developed to update the LSP results.Subsequently,the confusion matrix,the area under the receiver operating characteristic curve(AUC)and frequency ratio(FR)accuracy are used to evaluate the prediction performance of the above LSP models.The F1-score values of the SVM,SVM-NSDI and SVM-Updating models are 0.776,0.816 and 0.831,respectively.The AUC values are 0.869,0.903 and 0.914 and the FR accuracies are 0.795,0.853 and 0.873.It can be concluded that landslide susceptibility is a time-variant variable,which can be updated by considering the spatial correlation between landslides and surrounding slope units as well as the temporal effects of multi-temporal landslide inventory.This study provides a new framework to update landslide susceptibility over time and also provides more accurate LSP results for decisionmakers. | Zhilu Chang Faming Huang Jinsong Huang Shui-Hua Jiang Yuting Liu Sansar Raj Meena Filippo Catani | 2023 | Geoscience Frontiers2023，14，5： | 1 |

| 16 | In vitro and in vivo evaluation of cerium oxide nanoparticles in respiratory syncytial virus infection显示文摘Respiratory syncytial virus(RSV)is the most common cause of viral bronchiolitis among children worldwide,yet there is no vaccine for RSV disease.This study investigates the potential of cube and sphere-shaped cerium oxide nanoparticles(CNP)to modulate reactive oxygen(ROS)and nitrogen(RNS)species and immune cell phenotypes in the presence of RSV infection in vitro and in vivo.Cube and sphere-shaped CNP were synthesized by hydrothermal and ultrasonication methods,respectively.Physico-chemical characterization confirmed the shape of sphere and cube CNP and effect of various parameters on their particle size distribution and zeta potential.In vitro results revealed that sphere and cube CNP differentially modulated ROS and RNS levels in J774 macrophages.Specifically,cube CNP significantly reduced RSV-induced ROS levels without affecting RNS levels while sphere CNP increased RSV-induced RNS levels with minimal effect on ROS levels.Cube CNP drove an M1 phenotype in RSV-infected macrophages in vitro by increasing macrophage surface expression of CD80 and CD86 with a concomitant increase in TNFαand IL-12p70,while simultaneously decreasing M2 CD206 expression.Intranasal administration of sphere and cube-CNP were well-tolerated with no observed toxicity in BALB/c mice.Notably,cube CNP preferentially accumulated in murine alveolar macrophages and induced their activation,avoiding enhanced uptake and activation of other inflammatory cells such as neutrophils,which are associated with RSV-mediated inflammation.In conclusion,we report that sphere and cube CNP modulate macrophage polarization and innate cellular responses during RSV infection. | Akhil Patel Jessica Kosanovich Sameera Sansare Sricharani Balmuri Vinayak Sant Kerry M.Empey Shilpa Sant | 2023 | Bioactive Materials2023，，6： | 0 |
