Many time-resolved single-molecule biophysics experiments seek to characterize the kinetics of biomolecular systems exhibiting dynamics that challenge the time resolution of the given technique. Here, we present a general, computational approach to this problem that employs Bayesian inference to learn the underlying dynamics of such systems, even when they are much faster than the time resolution of the experimental technique being used. By accurately and precisely inferring rate constants, our Bayesian inference for the analysis of subtemporal resolution dynamics approach effectively enables the experimenter to super-resolve the poorly resolved dynamics that are present in their data.
许多时间分辨的单分子生物物理学实验试图描述生物分子系统的动力学特征,这些系统的动力学挑战了给定技术的时间分辨率。在这里,我们提出了一种通用的计算方法来解决这个问题,该方法使用贝叶斯推断来学习这些系统的潜在动力学,即使它们比所使用的实验技术的时间分辨率快得多。通过准确和精确地推断速率常数,我们的分析亚时间分辨率动力学的贝叶斯推断方法有效地使实验者能够超分辨其数据中存在的分辨率较差的动力学。
