Signaling Clock Timing

Science, 2008
Transcriptional feedback loops are at the heart of circadian clocks of mammals and other organisms, but evidence is emerging that suggests that other signaling mechanisms also have important roles in basic functions of the clock. O’Neill et al.

Signalling entrains the peripheral circadian clock

Cellular Signalling, 2020
In mammals, 24-h rhythms of behaviour and physiology are regulated by the circadian clock. The circadian clock is controlled by a central clock in the brain's suprachiasmatic nucleus (SCN) that synchronizes peripheral clocks in peripheral tissues. Clock genes in the SCN are primarily entrained by light.

Signaling in the Circadian Clock

2009
The plant circadian clock in is an internal-timing mechanism that provides adaption to daily environmental changes. Successive changes in light and temperature are able to reset the oscillator. The most prominent signal studied is light; temperature is a signal that is less well characterized.

Concurrent checking of clock signal correctness

IEEE Design & Test of Computers, 1998
Traditional concurrent-checking techniques may not detect the occurrence of the transient faults and resulting errors likely to affect clock signals in VLSI systems. The authors present a new method and self-checking circuit implementation for concurrently checking the correctness of clock distribution network signals in synchronous systems.

Clock and Timing Signals

2020
Clock signal network exists in computers and digital signal processing systems for controlling and performing their intended functions. A clock signal network has a high stability reference clock generator at the top of the network. The network has other clock generators and timing circuits.
