Universal Loop Statistics from Active Extrusion with Kinetic Barriers
A. Chervinskaya, R. Metzler, K. E. Polovnikov
We develop a kinetic theory of cohesin-driven loop extrusion on a disordered chromatin track with transient barriers. In the stationary state, the mean loop size is shown to obey a…
Universal scaling of segment fluctuations in polymer and chromatin dynamics
Kirill Polovnikov, Mehran Kardar
We demonstrate how center-of-mass (COM) motion influences polymer segment fluctuations. Cancellation of internal forces, together with spatially uncorrelated external noise, genera…
Generative inpainting of incomplete Euclidean distance matrices of trajectories generated by a fractional Brownian motion
Alexander Lobashev, Dmitry Guskov, Kirill Polovnikov
Fractional Brownian motion (fBm) features both randomness and strong scale-free correlations, challenging generative models to reproduce the intrinsic memory characterizing the und…
Largest eigenvalue statistics of sparse random adjacency matrices
Bogdan Slavov, Kirill Polovnikov, Sergei Nechaev +1
We investigate the statistics of the largest eigenvalue, , in an ensemble of large () sparse adjacency matrices, . The most attention is paid…
Topological and non-topological mechanisms of loops formation in chromosomes: effects on the contact probability
Kirill Polovnikov, Bogdan Slavov
Chromosomes are crumpled polymer chains further folded into a sequence of stochastic loops via loop extrusion. While extrusion has been verified experimentally, the particular mean…
Communities in C.elegans connectome through the prism of non-backtracking walks
Arsenii Onuchin, Alina Chernizova, Mikhail Lebedev +1
The fundamental relationship between the mesoscopic structure of neuronal circuits and organismic functions they subserve is one of the major challenges in contemporary neuroscienc…
