Query: Boundary regularity for parabolic systems in convex domains   In a cylindrical space-time domain with a convex, spatial base, we establish
a local Lipschitz estimate for weak solutions to parabolic systems with
Uhlenbeck structure up to the lateral boundary, provided homogeneous Dirichlet
data are assumed on that part of the lateral boundary.
