23. After submission of the manuscript, we learned from Michel Mareschal that the correct boundary condition (as described in Ref. 9) was used in all simulations. The phenomenon studied by Du et al. (Ref. 10) involving the loss of energy of some of the particles is not driven by the boundary conditions at the walls but rather by the inelasticity of the collisions between the particles. Thus their principal results ought to be substantially independent of the choice of boundary conditions. We also learned from Patricio Cordero that even though the velocity distribution on page 490 in the first paper cited in Ref. 11 is the incorrect one, the correct velocity distribution was actually used in the simulations.
