Modal degeneracy and oblique bending modes in ultra-long cable-strut deployable space masts

With the increasing application of large-scale ultra-long space deployable structures in aerospace engineering, low-order modal degeneracy and the resulting oblique bending modes have become critical issues affecting structural dynamic performance and on-orbit stability. This pap...

Frequency-Guided Feature Representation for Instance Segmentation in Aerial View Traffic Accident Scenes

Accurate instance-level perception of aerial view traffic accident scenes is the foundation of accident investigation. However, existing accident datasets mainly support event-level video analysis or coarse spatial localization, and rarely provide pixel-level vehicle masks togeth...

Early Jurassic Granitoids in the Pairigang Area, Tibet: Implications for the Evolution of the Neo-Tethyan Ocean and the Accretion of Juvenile Crust in the Southeastern Lhasa Block

The Jurassic represents one of the most significant periods within the widespread Mesozoic magmatism of the Lhasa Block; however, its formation age and petrogenesis have led to controversy over the deep genetic mechanisms responsible for magmatism. To address this, we present new...
