Abstract:

Abstract Introduction Consumer sleep trackers are useful for tracking daily sleep, particularly in shift-workers, yet large, multi-night validations against direct sleep measures are lacking. Conducted as one of the largest sleep tracker validation studies to date, this study evaluated performance of an under-mattress sensor (Withings Sleep Analyzer [WSA]) to classify sleep and wake versus polysomnography (PSG) in a multi-night laboratory protocol with both day and night sleep opportunities. Methods 27 healthy sleepers attended the laboratory twice, for 8 consecutive days (48% male, mean[SD] a

Abstract:

<em>Obstructive sleep apnea (OSA) is a medical condition in which the airway becomes obstructed regularly, and resulting in sleep disruption. Sleep apnea is a breathing condition in which a person stops breathing repeatedly while sleeping. OSA is usually diagnosed by an expensive procedure that requires the patient to remain in the hospital overnight. However, this method is expensive, inconvenient, and time consuming. Snoring, poor night sleeps due to choking or gasping, and waking up unrefreshed are all common symptoms of OSA. In this paper, we proposed the two deep pre-trained convolutional

Abstract Introduction Previous studies have used cluster analysis to clarify diagnostic heterogeneity of autism, but have been limited to identifying subgroups of autism on the basis of core symptoms rather than sleep problems.

The three sleeps were preceded by 4, 8, and 12 h of PRW, respectively.

Sleep is an evolutionally conserved behavior from vertebrates to invertebrates.

Self-rated sleep measures (from the Karolinska Sleep Diary) were obtained after each sleep and subjected to intraindividual regression analyses across time. Most subjective sleep measures showed a strong covariation across conditions. Subjective quality of sleep mainly involved variables of sleep continuity, in particular, perceived calmness of sleep and sl

The importance of assessing evolutionarily relevant social cues suggests that humans should be sensitive to others' sleep history, as this may indicate something about their health as well as their capacity for social interaction.

This suggests that one might also avoid contact with sleep-deprived, or sleepy-looking, individuals, as a strategy to reduce health risk and poor interactions.

Abstract:

Sleep disorders in children have a negative impact on mental and physical development, and a lack of sleep is one of the most important problems in infancy. At the age when naps are commonly accepted, the judgment of whether the amount of sleep is adequate has been based on the total amount of sleep per day. In other words, the idea is that even if the amount of sleep at night is insuﬃcient, it is not considered insuﬃcient if it is compensated for by taking a long nap or sleeping late on weekend mornings.

The sleep cycle is characterized by alternating non–rapid eye movement (NREM) and rapid eye movement (REM) sleeps. The mechanisms by which this cycle is generated are incompletely understood. We found that a transient increase of dopamine (DA) in the basolateral amygdala (BLA) during NREM sleep terminates NREM sleep and initiates REM sleep. DA acts on dopamine receptor D2 (Drd2)–expressing neurons in the BLA to induce the NREM-to-REM transition. This mechanism also plays a role in cataplectic attacks—a pathological intrusion of REM sleep into wakefulness—in narcoleptics. These results show a c

The aim of this research was to study whether a mobile, unguided Cognitive Behavioral Therapy-based Intervention for sleep problems, Sleep2, is feasible, acceptable, and potentially able to reduce mental health/sleep problems symptoms. Methods A single-arm, open-label, uncontrolled pre-post evaluation study was conducted with 487 registered participants: 283 started, 160 (56.55%) finished, out of which 95 completed without an ambulat

Sleeps disorders are a common disease overlooked by many people. Sleep disorder have many types and kinds and often associated with other severe illness such as diabetes, stroke, obesity and many others. Sleep monitors are one of many ways to read all parameters related to sleep and detect sleep disorders the subject has, however access to sleep monitor still expensive and tough to come by. Because of that accessibility, countless development of home sleep monitor occured around the world. However, most of that device still hard to operate and some of them gives error readings of parameters. B

Abstract:

Researchers have investigated several different sense amplifiers’ yield and other quantitative features. Amplification is required for various power-saving methods, including the sleep transistor, the sleep stack, the sleepy keeper, and others. This study aims to evaluate how much energy is consumed by the many different sense amplifier topologies. Simulations have shown that adopting a sleep transistor approach can significantly reduce the amount of power lost even while operating at 1.2V.

Abstract:

AbstractThe theory that the people of the early modern period slept in well-defined segments of ‘first’ and ‘second’ sleeps has been highly influential in both scholarly literature and mainstream media over the past twenty years. Based on a combination of scientific, anthropological and textual evidence, the segmented sleep theory has been used to illuminate discussions regarding important aspects of early modern nocturnal culture; mainstream media reports, meanwhile, have proposed segmented sleep as a potentially ‘natural’ and healthier alternative to consolidated blocks of sleep.

This condition is most common on male population with obese body. A prosthodontist can try to help by providing oral appliances (OA) for patient to use while they were asleep. OA were designed to thrust mandible forward and downward so that minimalize the chance for obstruction of upper airways to occur.

AbstractThe only extant choliambic line by Cinna, comparing some action to a Psyllus doing something to an asp, is preserved by Aulus Gellius to illustrate that the adjectivesomniculosuscan have the causative sense ‘sleep-inducing’ as well as the active one of ‘sleepy’. If Gellius is correct, then the simile’s missing verb is likely to have one of the Psylli, famed for their ability to lull snakes to sleep, doing just that to a ‘sleep-inducing asp’. The situation which would be compared to this must be that of someone receiving a taste of their own medicine. This would also account for the Psy
