DN1p or the “Fluffy” Cerberus of Clock Outputs

Insect circadian clock outputs.

Insects display an impressive variety of daily rhythms, which are most evident in their behaviour. Circadian timekeeping systems that generate these daily rhythms of physiology and behaviour all involve three interacting elements: the timekeeper itself (i.e. the clock), inputs to the clock through which it entrains and otherwise responds to environmental cues such as light and temperature, and ...

Ultradian clock timekeeping: periodic, quasiperiodic and chaotic outputs

Oscillator models for the control of the cell division cycle date back to 1970 when Sel'kov suggested a thiol/disulphide cycle and Gilbert proposed a specific protein phosphorylation-dephosphorylation cycle as state controlling variables; cell division requires attainment of a critical threshold. We have used the Chernavskii et al. (1977) model (relaxation oscillator) and modulated its output u...

Cerberus’05 Team Report

The Renaissance or the cuckoo clock.

'…in Italy, for thirty years under the Borgias, they had warfare, terror, murder and bloodshed, but they produced Michelangelo, Leonardo da Vinci and the Renaissance. In Switzerland, they had brotherly love, they had five hundred years of democracy and peace-and what did that produce? The cuckoo clock'. Orson Welles as Harry Lime: The Third Man. Orson Welles might have been a little unfair on t...

Investigations into the Cerberus Outflow Channels, Mars

Mars Orbiter Camera (MOC) images and Mars Orbiter Laser Altimeter (MOLA) data on the Mars Global Surveyor (MGS) spacecraft show evidence for three catastrophic outflow channels around the Cerberus Plains region, Mars. The morphologies seen in MOC images located within channels seen in gridded MOLA topography are similar to those found in catastrophic flood terrains on Earth, such as the Channel...
