      abstract     = {The dynamical deformation of ultrasoft colloids as well as
                      their dynamic frictional forces are numerically
                      investigated, when one colloid is dragged past another at
                      constant velocity. Hydrodynamic interactions are captured by
                      a particle-based mesoscopic simulation method. At vanishing
                      relative velocity, the equilibrium repulsive force-distance
                      curve is obtained. At large drag velocities, in contrast, we
                      find an apparent attractive force for departing colloids
                      along the dragging direction. The deformation, in the close
                      encounter of colloids, and the energy dissipation are
                      examined as a function of the drag velocity and their
                      separation.},
