Hibernation is an adaptation for energy conservation, which probably evolved as an extension of non-rapid-eye-movement sleep mechanisms. Yet, during periodic arousals from bouts of deep hibernation, ground squirrels (Spermophilus lateralis) spend most of their time asleep. Spectral analysis of the electroencephalogram revealed that cortical slow-wave intensity during sleep is high at the beginn...

Hibernation is a physiological adaptation to overcome extreme environmental conditions. It is characterized by prolonged periods of torpor interrupted by temporary arousals during winter. During torpor, body functions are suppressed and restored rapidly to almost pre-hibernation levels during arousal. Although molecular studies have been performed on hibernating rodents and bears, it is unclear...

Torpor in hibernating mammals defines the nadir in mammalian metabolic demand and body temperature that accommodates seasonal periods of reduced energy availability. The mechanism of metabolic suppression during torpor onset is unknown, although the CNS is a key regulator of torpor. Seasonal hibernators, such as the arctic ground squirrel (AGS), display torpor only during the winter, hibernatio...

Hibernation,a form of cold-adaptationfoundpimarify in rmmrmhn “ species, involvesmarked declines in bcdy temperature, heart rate, respiration, and metabolicrate. WehaveidentifiedseveralISI@research fronts related to hibernation, including thersnogenesis(heat production), thermoregufation, and other forms of cold-adaptation. Many aspects of hibernation remain unexplained, and researchers continu...

during hibernation period from mid october to late march, we removed testis of laudakia caucasia. based on histological and statistical analyses we obtained two phases in spermatogenesis in this lizard as follows: (a) from october to december, in which the spermatogenesis is inactive and (b) from january to march, in which the spermatogenesis is active. spermatogenesis during late hibernation o...

BACKGROUND During hibernation the kidney is in a hypothermic condition where renal blood flow is minimal and urine production is much reduced. Periodical arousal from hibernation is associated with kidney reperfusion at increasing body temperature, and restored urine production rate. METHODS To assess the degree of structural preservation during such extreme conditions, the kidney cortex was ...

This paper presents the first analysis of the new hibernation file format that is used in Windows versions 8, 8.1, and 10. We also discuss several changes in the hibernation and shutdown behavior of Windows that will have a direct impact on digital forensic practitioners who use hibernation files as sources of
