The difference between night and day.

Day and Night: Circadian Rhythms in Worms

Most organisms seem to show ‘‘circadian rhythms’’—cycles of behaviour or gene expression that repeat roughly every 24 hours. Such cycles represent an internal circadian clock that can be ‘‘entrained,’’ or synchronized, to a regular light/dark or temperature cycle, and will then continue to cycle in the absence of the light or temperature stimulus. In the nematode worm Caenorhabditis elegans, ho...

Vehicle Detection under Day and Night Illumination

Effective detection of vehicles in urban traffic scenes can be achieved by exploiting image analysis techniques. Nevertheless, vehicle detection in daytime and at night can’t be approached with the same image analysis algorithms, due to the strongly different illumination conditions. This paper describes the two different sets of image analysis algorithms that have been used in the VTTS system ...

All day, and all of the night.

Motor memory consolidation, night and day.
