We consider a wireless sensor network, where nodes switch between an active (on) and a sleeping (off) mode, to save energy. Their switching on/off schedules are completely non-coordinated. Their positions are distributed according to a Poisson process, and ...
Replenishment of brain glycogen stores depleted during waking has been suggested to constitute one of the functions of sleep [Benington, J. H. & Heller H. C. (1995) Prog. Neurobiol., 45, 347]. We have tested the hypothesis that the level of expression of e ...
Acquisition and reacquisition of skills is a main pillar of functional recovery after stroke. Nighttime sleep has a positive influence on motor learning in healthy individuals, whereas the effect of daytime sleep on neuro-rehabilitative training and relear ...
Sleep after learning often enhances task performance, but the underlying mechanisms remain unclear. Using a well-characterized rotation learning paradigm implemented both behaviorally and in computer simulations, we compared two main hypotheses: the first, ...
Energy consumption of the Internet is already substantial and it is likely to increase as operators deploy faster equipment to handle popular bandwidth-intensive services, such as streaming and video-on-demand. Existing work on energy saving considers loca ...
We studied the effects of chloramphenicol on brain glucose utilization and sleep-wake cycles in rat. After slightly anaesthetized animals were injected with [18F]fluoro-2-deoxy-D-glucose, we acquired time-concentration curves from three radiosensitive beta ...
