We have picked a sign convention throughout for
in which a convex body
(such as a sphere with the ``solid'' region being inside, or any
Wulff shape) has positive 
.
This sign convention is opposite to that in [4] and in
differential
geometry, where the mean curvature vector points in the direction in which
the
surface curves and which is thus a negative multiple of the unit normal
vector
for a convex body, but it is in
accordance to the way the isotropic Gibbs-Thomsen equation
is typically written:

or detachment. The velocity is assumed to be an odd function of
