Reverse-time analysis and boundary classification of directional biological dynamics with multiplicative noise

Authors Lenner N, Häring M, Eule S, Großhans J, Wolf F   Journal ArXiv   Citation arXiv:2304.04279.   Abstract The dynamics of living systems often serves the purpose of reaching functionally important target states. We previously proposed a theory to analyze stochastic biological dynamics evolving towards target states in reverse

Reverse-time analysis uncovers universality classes in directional biological dynamics

Authors Lenner N, Eule S, Großhans J, Wolf F Journal Arxiv Citation arXiv:2304.03226. Abstract Mesoscopic bio-systems typically evolve towards functionally important target states, such as cell-cycle checkpoints or decision boundaries for the release of specific behaviors. For the data-driven inference of the underlying directional out-of-equilibrium dynamics, we here develop a

Effects of cryo-EM cooling on structural ensembles

Authors Bock LV, Grubmüller H Journal Nature Communications Citation Nat Commun. 2022 Mar 31;13(1):1709. Abstract Structure determination by cryo electron microscopy (cryo-EM) provides information on structural heterogeneity and ensembles at atomic resolution. To obtain cryo-EM images of macromolecules, the samples are first rapidly cooled down to cryogenic temperatures. To what
