Self-ratcheting Stokes drops driven by oblique vibrations
, 2009 We develop and analyze a minimal hydrodynamic model in the overdamped limit to understand why a drop climbs a smooth homogeneous incline that is harmonically vibrated at an angle different from the substrate normal [Brunet, Eggers and Deegan, Phys.

Role of vibrations in the jamming and unjamming of grains discharging from a silo [PDF]
, 2009 We present experimental results of the jamming of non-cohesive particles discharged from a flat bottomed silo subjected to vertical vibration. When the exit orifice is only a few grain diameter wide, the flow can be arrested due to the formation of ...
