Methods of drilling subterranean formations with rotary drag bits equipped with cutting elements including superabrasive, multi-aggressive cutting faces or profiles which are especially suitable for drilling formations of varying hardness and for directional drilling through formations of varying hardness are disclosed. The present invention uses time-staggered beacon time slots to provide improved beacon-acquisition performance. The mixing zone includes a high speed area with a constant cross section, and a diffusion area with a flared cross section downstream of the high speed area in the hot gas direction. adjacent the skull, the tympanic membrane, the hammer, the incus, the stapes, the outside of the cochlea, the otic capsule, the round window membrane, or the oval window membrane. At a point in time when the virtual machine has transitioned to a hibernation state, from consideration as to whether the data of the main memory of the virtual machine stored in the auxiliary storage device is unnecessary, data stored in the auxiliary storage device is rewritten in order to reduce the data.
