摘要翻译:
我们从理论上研究了Einstein和Onsager关系的违反性,并利用Kafri{\em et al.}提出的两态模型的推广,研究了单个过程马达在远离平衡时的效率[Biophys.J.{\BF 86},3373(2004)]。借助于涨落定理,我们分析了这些违规和这种效率的一般特征,并将它们与电机的机械力化学联轴器联系起来。特别是,利用我们的框架对kinesin的实验数据进行了分析,得出了有趣的预测,这些预测可能会为未来的实验提供指导。

英文摘要:
We investigate theoretically the violations of Einstein and Onsager relations, and the efficiency for a single processive motor operating far from equilibrium using an extension of the two-state model introduced by Kafri {\em et al.} [Biophys. J. {\bf 86}, 3373 (2004)]. With the aid of the Fluctuation Theorem, we analyze the general features of these violations and this efficiency and link them to mechanochemical couplings of motors. In particular, an analysis of the experimental data of kinesin using our framework leads to interesting predictions that may serve as a guide for future experiments.
