EFFECT OF CELLULAR MEMBRANE RESISTIVITY INHOMOGENEITY ON THE THERMAL NOISE-LIMIT
Our objective is to generalize the Weaver-Astumian (WA) and Kaune (KA) models of thermal noise limit to the case of cellular membrane resistivity asymmetry. The asymmetry of resistivity causes different effects in the two models. In the KA model, asymmetry decreases the characteristic field strength of the thermal limit over and increases it below the breaking frequency (10ï· ĂŻâŹÂœĂŻÂŽ mĂŻâŹÂ), while asymmetry decreases the spectral field strength of the thermal noise limit at all frequencies. We show that asymmetry does not change the character of the models, showing the absence of thermal noise limit at high and low frequencies in WA and KA models, respectively
Nonequilibrium Thermodynamic and Quantum Model of a Damped Oscillator
We describe the linearly damped harmonic quantum oscillator in Heisenbergâs interpretation by Onsagerâs thermodynamic equations. Ehrenfestâs theorem is also discussed in this framework. We have also shown that the quantum mechanics of the dissipative processes exponentially decay to classical statistical theory
