Biography of David F. Cavers [PDF]
, 1977 A method for backstepping control of rigid body motion is proposed. The control variables are torques and the force along the axis of motion. The proposed control law and lyapunov function guarantee asymptotic stability from all initial values except one

Mobile Formation Coordination and Tracking Control for Multiple Non-holonomic Vehicles
, 2019 This paper addresses forward motion control for trajectory tracking and mobile formation coordination for a group of non-holonomic vehicles on SE(2). Firstly, by constructing an intermediate attitude variable which involves vehicles' position information

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Combined Static and Motion Features for Deep-Networks Based Activity Recognition in Videos
, 2018 Activity recognition in videos in a deep-learning setting---or otherwise---uses both static and pre-computed motion components. The method of combining the two components, whilst keeping the burden on the deep network less, still remains uninvestigated ...

Suppressing nano-scale stick-slip motion by feedback [PDF]
, 2012 When a micro cantilever with a nano-scale tip is manipulated on a substrate with atomic-scale roughness, the periodic lateral frictional force and stochastic fluctuations may induce stick-slip motion of the cantilever tip, which greatly decreases the ...

FEBS Letters, EarlyView.This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Decomposing of lubricating oil caused the blackening wear of porous polyimide—Or is it?
FrictionIn practical applications, the pocket surface of a porous polyimide (PPI) cage often experiences blackening wear, which may lead to lubrication failure. However, the mechanism of blackening wear is still controversial. In this study, the impact of oxygen
