Investigation on tunnel stability considering pipe‐roof support with transparent soil technology

Deep Underground Science and Engineering, EarlyView.
This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

Host‐mediated filtering and interspecific associations structure strongyle parasite communities in Sable Island horses

Journal of Animal Ecology, EarlyView.
Using individual‐level nemabiome metabarcoding of 3147 samples from 916 horses on Sable Island over 10 years, we generate the largest dataset of its kind to date. This unprecedented scale enables a rare test of the processes structuring parasite communities in a natural system, revealing dominant host‐mediated filtering and predominantly positive ...
