      abstract     = {In our recent work on concentrated suspensions of uniformly
                      porous colloidal spheres with excluded volume interactions,
                      a variety of short-time dynamic properties were calculated,
                      except for the rotational self-diffusion coefficient. This
                      missing quantity is included in the present paper. Using a
                      precise hydrodynamic force multipole simulation method, the
                      rotational self-diffusion coefficient is evaluated for
                      concentrated suspensions of permeable particles. Results are
                      presented for particle volume fractions up to $45\%$ and for
                      a wide range of permeability values. From the simulation
                      results and earlier results for the first-order virial
                      coefficient, we find that the rotational self-diffusion
                      coefficient of permeable spheres can be scaled to the
                      corresponding coefficient of impermeable particles of the
                      same size. We also show that a similar scaling applies to
                      the translational self-diffusion coefficient considered
                      earlier. From the scaling relations, accurate analytic
                      approximations for the rotational and translational
                      self-diffusion coefficients in concentrated systems are
                      obtained, useful to the experimental analysis of
                      permeable-particle diffusion. The simulation results for
                      rotational diffusion of permeable particles are used to show
                      that a generalized Stokes-Einstein-Debye relation between
                      rotational self-diffusion coefficient and high-frequency
                      viscosity is not satisfied.},
