It was proposed that the electrically controllable bistability
originated from the metal filament formation (ON state) and breakdown (OFF state) between two electrodes, which will be discussed in detail in Filament Formation in Polythiophene Memory Materials section.
Dynamical analysis of the mathematical model revealed the existence of bistability
when the promoter strengths of repression are matched.
Third-order NLO effects include frequency tripling (THG), intensity dependent index of refraction, and optical bistability
This phenomenon--where at a given external condition, a system can reside in one of two available stable steady states--is known as bistability
We found that bistability
was linked to a positive feedback loop between MprA and SigE, a protein that binds to RNA polymerase to promote the production of both MprA and SigE.
Oscillations and bistability
in heterogeneous catalytic reactions are well known.
Polynitrile is a typical conjugated polymer, and was found to exhibit unusually large third-order susceptibility and hyperpolarizability  as well as excellent and reproducible electrical bistability
Therefore, the proposed strategy is paving the way to specific and remarkable properties such as magnetic bistability
or photo-dynamic therapy while enlarging the applications panel.
