Query: On asymptotic speed of solutions to level-set mean curvature flow
  equations with driving and source terms   We investigate a model equation in the crystal growth, which is described by
a level-set mean curvature flow equation with driving and source terms. We
establish the well-posedness of solutions, and study the asymptotic speed.
Interestingly, a new type of nonlinear phenomena in terms of asymptotic speed
of solutions appears, which is very sensitive to the shapes of source terms.
