(4) TEC-CTR in the daytime post-noon hours (12 14 LT) does not vary much with the solar activity, however, TEC-CTR in the post-sunset hours (19 21 LT) shows a clear dependence on the solar activity, its values increasing with solar activity.
Recall was significantly reduced in the aligned mice compared to the daytime tests (post hoc p < 0.001), but did not significantly change with time of day in misaligned mice (post hoc p = 0.3).
The foF2 values (both observed and predicted) show typical features of daytime peak and post-midnight minimum peak.
e Higher than daytime work, 2nd post-call night, and Saturday.
Compared with memory performance after a retention period of daytime wakefulness, both post-learning nocturnal sleep, as well as acute sleep deprivation at retrieval significantly enhanced false recall of theme words in subjects with low general memory performance.
For the December solstice season, both NmF2URSI and NmF2CCIR underestimate NmF2obs during the daytime hours except during post-noontime to sunset hours, when they overestimate those observed.
Previous studies have noted the risks inherent in daytime sleepiness during the post-call period, including potential adverse patient outcomes [ 1, 2].
"I asked myself 'What happens if you use the app during daytime?'" Sæløen told The Huffington Post.
Next, the monitoring period for studying the effects of daytime work, night call, and post night-call on the various measures was chosen to fit each individual's work schedule.
The striking features in the diurnal cycle given in Fig. 2 are near sunrise minima and a sharp increase during daytime to reach well-defined post-sunset maxima at about 2000 LT for all seasons for calculated hmF2 data.
Self-reported mean (SD) scores of daytime sleepiness also decreased significantly post-intervention from 16.5 (6.0) to 11.3 (6.0) (p < 0.001).
