Binding of bivalent transcription factors to active and inactive regions folds human chromosomes into loops, rosettes and domains
C. A. Brackley, J. Johnson, S. Kelly +2
Biophysicists are modeling conformations of interphase chromosomes, often basing the strengths of interactions between segments distant on the genetic map on contact frequencies de…
A 1-dimensional statistical mechanics model for nucleosome positioning on genomic DNA
S. Tesoro, I. Ali, A. N. Morozov +2
The first level of folding of DNA in eukaryotes is provided by the so called '10 nm chromatin fibre', where DNA wraps around histone proteins (approx. 10 nm in size) to form nucleo…
Clustering and pattern formation in chemorepulsive active colloids
Benno Liebchen, Davide Marenduzzo, Ignacio Pagonabarraga +1
We demonstrate that migration away from self-produced chemicals (chemorepulsion) generates a generic route to clustering and pattern formation among self-propelled colloids. The cl…
Hydrodynamic oscillations and variable swimming speed in squirmers close to repulsive walls
Juho S. Lintuvuori, Aidan T. Brown, Kevin Stratford +1
We present a lattice Boltzmann study of the hydrodynamics of a fully resolved squirmer, radius R, confined in a slab of fluid between two no-slip walls. We show that the coupling b…
Light-induced self-assembly of active rectification devices
J. Stenhammar, R. Wittkowski, D. Marenduzzo +1
Self-propelled colloidal objects, such as motile bacteria or synthetic microswimmers, have microscopically irreversible individual dynamics - a feature they share with all living s…
Active Model H: Scalar Active Matter in a Momentum-Conserving Fluid
Adriano Tiribocchi, Raphael Wittkowski, Davide Marenduzzo +1
We present a continuum theory of self-propelled particles, without alignment interactions, in a momentum-conserving solvent. To address phase separation we introduce a scalar conce…
Field-controlled columnar and planar patterning of cholesteric colloids
Giuseppe D'Adamo, D. Marenduzzo, C. Micheletti +1
We study how dispersions of colloidal particles in a cholesteric liquid crystal behave under a time-dependent electric field. By controlling the amplitude and shape of the applied…
Topological Patterns in Two-dimensional Gel Electrophoresis of DNA Knots
Davide Michieletto, Davide Marenduzzo, Enzo Orlandini
Gel electrophoresis is a powerful experimental method to probe the topology of DNA and other biopolymers. While there is a large body of experimental work which allows us to accura…
A minimal physical model captures the shapes of crawling cells
E. Tjhung, A. Tiribocchi, D. Marenduzzo +1
Cell motility in higher organisms (eukaryotes) is crucial to biological functions ranging from wound healing to immune response, and also implicated in diseases such as cancer. For…
Motility-induced phase separation and coarsening in active matter
Giuseppe Gonnella, Davide Marenduzzo, Antonio Suma +1
Active systems, or active matter, are self-driven systems which live, or function, far from equilibrium - a paradigmatic example which we focus on here is provided by a suspension…
