Pattern‐Aware Intelligence Enables Nondestructive, Rapid Quantification of High‐Aspect‐Ratio Silicon Etching

Advanced Science, Volume 13, Issue 57, 14 October 2026.
Pattern‐dependent etching is converted into a physical prior for intelligent reconstruction of high‐aspect‐ratio silicon structures. Combining YOLO‐Pose feature extraction with a topography network, the framework retrieves depth, sidewall angle, and scallop texture from minimal destructive observations, enabling accurate cross‐scale metrology and near ...

Geomorphic Imprints of Coseismic Uplift: Knickpoints and Landslides on the Noto Peninsula, Japan

Earth Surface Processes and Landforms, Volume 51, Issue 10, October 2026.
River knickpoints and slow‐moving landslides show complementary spatial relationships with the vertical and horizontal deformation fields of the 2024 Mw 7.5 Noto Peninsula earthquake. Together, their distributions provide geomorphic information for evaluating cumulative landscape adjustment to repeated coseismic uplift at a regional scale.
