Radio polarimetry is an invaluable tool to investigate the physical conditions and variability processes in active galactic nuclei (AGN) jets. However, detecting their linear and circular polarization properties is a challenging endeavor due to their low

FEM–DEM modeling of pseudo static experiments on scaled‐down rockfill dams with dry stone pitching
Abstract Rockfill dams with stone pitching are specific hydraulic structures generally built in the early XXth century where stones used to be hand‐placed without mortar to constitute the upward and downward dam faces. Few studies have been carried out to quantify the specific and critical role of the pitching in the dam stability against both static ...

Mapping rill soil erosion in agricultural fields with UAV‐borne remote sensing data
An automatic workflow is introduced to map erosion rills at field scale in UAV‐photogrammetry derived digital elevation models by considering topographic features and machine learning. Abstract Soil erosion by water is a main form of land degradation worldwide.

Detection and Delineation of Sorted Stone Circles in Antarctica
Sorted stone circles are natural surface patterns formed in periglacial environments. Their relation to permafrost conditions make them very helpful for better understanding the past climates where they were formed and have evolved and also for ...
