Human endogenous circadian rhythms are coordinated by the suprachiasmatic nucleus of the hypothalamus, with a day/night cycle of approximate 24 hours, which is synchronized to the environmental clues stimulated by the cycles of activity/rest, sleep/wake, and/or fasting/feeding.22 Delaying bedtime ...
and it begins in the lighter stages of sleep before enteringdeep sleepand eventually REM (rapid eye movement). During a typical night of sleep, we complete roughly five sleep cycles.
The sleep period subdivided into a sequence of sub-periods each of known duration wherein the durations of the sub-periods are not necessarily integer multiples of cycles of the sleep clock. Elapsed time is tracked within each individual sub-period of the sleep period using an integer sleep ...

During prolonged temporal isolation in caves or windowless rooms, human subjects often develop complicated sleep-wake patterns. Seeking lawful structure in these patterns, we have reanalyzed the spontaneous timing of 359 sleep-wake cycles recorded from 15 internally desynchronized human subjects. The obs...
Solar cycle length is a useful indicator of long term changes insolar activity. When the sun gets hotter, we observe shorter solar cycles. When the sun shows a long term coolingtrend, solar cycle length is longer. A 1991 study by Friis-Christensen and Lassen smoothed out data on solar cycle...
cycles of denaturing at 94 °C for 15 s and annealing and extension for 2 min at 54 °C, for telomere amplification; and 30 cycles of denaturing at 94 °C for 15 s followed by annealing and extension for 2 min at 60 °C for36B4amplification. We confirmed the specificity of the ...
We found no associations between the quality of mothers’ sleep during pregnancy and LTL of newborn children, as measured from blood leukocytes sampled at birth. We were also unable to replicate previous findings related to maternal wellbeing during pregnancy and newborn LTL, despite our sample si...

Ah, sure, time to go to sleep I guess XD. But I think this would also need to address custom properties registered as<integer>or<number>(https://drafts.css-houdini.org/css-properties-values-api/#dependency-cycles): --foo:calc(2ex/10px);font-weight:var(--foo); ...
