Not gone with the wind: Active microscale flight with highly porous bristled wings

Pedro Miguel Nunes Pereira de Almeida Reis, Yuexia Luna Lin

The finesse of sub-millimeter insect flight with comb-like bristled wings raises intriguing questions, not only on fluid-structure interactions (FSI) but also on the mechanical behavior of the underlying, highly porous structures. Farisenkov et al. charact ...

AcinoSet: A 3D Pose Estimation Dataset and Baseline Models for Cheetahs in the Wild

Alexander Mathis, Mackenzie Mathis

Animals are capable of extreme agility, yet understanding their complex dynamics, which have ecological, biomechanical and evolutionary implications, remains challenging. Being able to study this incredible agility will be critical for the development of n ...
