Rhythmic ring–ring stacking drives the circadian oscillator clockwise [PDF]
Proceedings of the National Academy of Sciences, 2012 The oscillator of the circadian clock of cyanobacteria is composed of three proteins, KaiA, KaiB, and KaiC, which together generate a self-sustained ∼24-h rhythm of phosphorylation of KaiC. The mechanism propelling this oscillator has remained elusive, however. We show that stacking interactions between the CI and CII rings of KaiC drive the transition

Merging of optoelectronic techniques for microwave signal generation [PDF]
, 2007 This paper describes some recent evolutions about optical generation of microwave signals. Among these, multiloop ring oscillator and harmonic generation allow both rise in frequency and wide tunability. Besides, using microresonators and optical sources

Consideration for Affects of an XOR in a Random Number Generator Using Ring Oscillators
Entropy, 2021 A cloud service to offer entropy has been paid much attention to. As one of the entropy sources, a physical random number generator is used as a true random number generator, relying on its irreproducibility.

Quantum ring models and action-angle variables
, 2010 We suggest to use the action-angle variables for the study of properties of (quasi)particles in quantum rings. For this purpose we present the action-angle variables for three two-dimensional singular oscillator systems.
