DEM investigation of breakage-induced deformation and mesoscale damage evolution in rockfill under slow cyclic loading

Periodic water-level fluctuations in pumped-storage hydropower stations impose long-term slow cyclic loading on rockfill materials. This study investigates the macroscopic–mesoscopic evolution of rockfill materials under cyclic loading using the discrete element method (DEM). A m...

High-resolution land cover mapping from coarse labels via a noisy label learning-guided cross-scale framework

High-resolution remote sensing images (HRSIs) provide essential data support for land cover mapping, where deep learning has shown great promise. However, deep learning-based methods rely on abundant high-quality annotations, while low-resolution coarse labels are difficult to us...

Remote sensing-based monitoring of water hyacinth invasion dynamics and socioeconomic impacts in Lake Abaya, Ethiopia

Abstract Water hyacinth, an invasive aquatic plant originally from the Amazon Basin, has posed a severe threat to the Lake Abaya ecosystem since 1990. This study utilized Sentinel-2A satellite imagery from 2017 to 2023 to analyse the spatiotemporal dynamics and socioeconomic impa...
