Topological delocalisation of confined 3D active nematics
Louise C. Head, Pasquale Digregorio, Davide Marenduzzo +3
Defect lines in 3D active nematic systems are intriguing topological singularities whose out-of-equilibrium dynamics remain elusive in confined settings. Here, we numerically study…
Flow of deformable droplets: self-pinned glasses and string-like flow
Achille Quarante, Michael Chiang, Davide Marenduzzo +1
We investigate, through numerical simulations, the rheology of a dry suspension of deformable droplets under pressure-driven flow. The system exhibits two force-driven dynamical tr…
Passive polymers in active turbulence undergo a collapse-stretch transition
Zahra K. Valei, Davide Marenduzzo, Tyler N. Shendruk
Active processes in living systems generate nonequilibrium forces that deform embedded passive macromolecules. To understand how such dynamics influence polymer conformation, we st…
Modelling transcriptional silencing and its coupling to 3D genome organisation
Massimiliano Semeraro, Giuseppe Negro, Davide Marenduzzo +1
Timely up- or down-regulation of gene expression is crucial for cellular differentiation and function. While gene upregulation via transcriptional activators has been extensively i…
Intercellular Friction and Motility Drive Orientational Order in Cell Monolayers
Michael Chiang, Austin Hopkins, Benjamin Loewe +2
Spatiotemporal patterns in multicellular systems are important to understanding tissue dynamics, for instance, during embryonic development and disease. Here, we use a multiphase f…
