We thank V. V. Brazhkin and Daan Frenkel for stim- ulating discussions. Our special thanks to Prof. Ch. Chakravarty who attracted our attention to the prob- lems considered here. The work was supported in part by the Russian Foundation for Basic Research (Grant No 08-02-00781). FIG. 14: The diffusion scaling with the excess entropy at (a) high and (b) low temperatures for the soft repulsive shoulder system. by a mixture of hard spheres of two different sizes. The concentration of components of such mixture is pressure and temperature dependent. As it was shown in liter- ature (see, for example, [69]) the excess entropy scaling holds for binary mixtures too. But in the case of quasi- binary mixture since the effective concentration depends on the pressure and temperature the behavior becomes more complex. This brings to the breakdown of the scal- ing rules for this case. Obviously, the systems with bounded potentials can not be approximated by hard sphere potentials too. It seems that this may be the reason of violation of Rosen- [1] P. Debenedetti, J. Phys.: Condens. Matter 15, R1669 (2003). [2] S. V. Buldyrev, G. Franzese, N. Giovambattista, G. Malescio, M. R.
