Stationary wave patterns generated by an impurity moving with supersonic velocity through a Bose-Einstein condensate [PDF]
, 2009 Formation of stationary 3D wave patterns generated by a small point-like impurity moving through a Bose-Einstein condensate with supersonic velocity is studied. Asymptotic formulae for a stationary far-field density distribution are obtained.

Periodic shedding of vortex dipoles from a moving penetrable obstacle in a Bose-Einstein condensate
, 2015 We investigate vortex shedding from a moving penetrable obstacle in a highly oblate Bose-Einstein condensate. The penetrable obstacle is formed by a repulsive Gaussian laser beam that has the potential barrier height lower than the chemical potential of ...

Velocity oscillations in actin-based motility [PDF]
, 2007 We present a simple and generic theoretical description of actin-based motility, where polymerization of filaments maintains propulsion. The dynamics is driven by polymerization kinetics at the filaments' free ends, crosslinking of the actin network ...

IEEE AccessThe steering behavior of autonomous agents in animation and games aims to form agent movement to navigate around a virtual world. Leader-following behavior is a steering behavior formed by followers who must follow their leader while the leader guides the group to their destination. Followers need to deter themself from crowding their leader as it will
