DESCRIPTION:Mass transport by the motion of 3D vortex filaments is studied
 . Perhaps the simplest example of such a transport is one by a vortex ring
 . As another example\, we recently demonstrated that a 3D vortex soliton (
 Hasimoto soliton) can also transport mass along with its propagation. The 
 common features of the transport\, one by a vortex ring and the other by a
  vortex\, is that some fluid particles move in closed orbits which make kn
 ots with the vortices. For the analysis of the mechanism of this trapping\
 , a model composed of two straight vortex filaments in the 3D space\, whic
 h is called the chopsticks model\, is presented. We report mass transport 
 by this model. \n\n
