Superdiffusion in a Model for Diffusion in a Molecularly Crowded Environment
Dietrich Stauffer, Christian Schulze, Dieter W. Heermann
We present a model for diffusion in a molecularly crowded environment. The model consists of random barriers in percolation network. Random walks in the presence of slowly moving b…
The influence of the cylindrical shape of the nucleosomes and H1 defects on properties of chromatin
P. M. Diesinger, D. W. Heermann
We present a model improving the two-angle model for interphase chromatin (E2A model). This model takes into account the cylindrical shape of the histone octamers, the H1 histones…
Chromatin Folding in Relation to Human Genome Function
Julio Mateos-Langerak, Osdilly Giromus, Wim de Leeuw +6
Three-dimensional (3D) chromatin structure is closely related to genome function, in particular transcription. However, the folding path of the chromatin fiber in the interphase nu…
Percolation in a Class of Band Structured Random Matrices
Dieter W. Heermann, Manfred Bohn
We define a class of random matrix ensembles that pertain to random looped polymers. Such random looped polymers are a possible model for bio-polymers such as chromatin in the cell…
Monte Carlo simulations reveal the straightening up of an end-grafted flexible chain with a rigid side chain
Marcel Hellmann, Matthias Weiss, Dieter W. Heermann
We have studied the conformational properties of a flexible end-grafted chain (length ) with a rigid side chain (length ) by means of Monte Carlo simulations. Depending on th…
A Random Loop Model for Long Polymers
Manfred Bohn, Dieter W. Heermann, Roel van Driel
While the structure of chromatin has been studied in great detail on length scales below 30 nm, amazingly little is known about the higher-order folding motifs of chromatin in inte…
