26.To keep the temperature constant, every 50 time steps the velocities of all the particles were replaced by new velocities which were drawn from the Boltzmann distribution for the corresponding temperature.

28.The 10 initial configurations differ drastically in their thermal history and are therefore completely independent. They were started at and, after various cooling and reheating periods, were equilibrated at Details can be found in Refs. 25, 29.

38.In Fig. 11 and in all following figures the errorbars are standard deviations of the mean, which have been determined from the 10 independent runs. The student’s t-test, taking into account the covariance, agrees with the judgment by eye as to when the mean values are significantly different. For example in Fig. 11 the significance levels are in the range of 0.96 and 0.9995
39.A similar effect has been found in the case of a soft sphere glass at low temperatures for the particles participating in a soft mode (see Ref. 14).
40.Specific to our potential with are mobile/immobile A particles also energetically less/more bound when surrounded by fewer/more B particles.
