We also present a numerical result regarding this temperature for a thermal ratchet model. Furthermore, our expression of efficiency using known values for kinesin can adequately explain the experimental results. The framework presented here has a closed form phenomenologically, and is independent of any detailed models.4 pages, 2 figures (1 color figure)Statistical MechanicsSoft Condensed Mattertext
