Author(s): Kaikai Zheng, Zitong Zhang, Bingyang Cao, and Steve Granick It is unsatisfactory that regarding the problem of entangled macromolecules driven out of equilibrium, experimentally based understanding is usually inferred from the ensemble average of polydisperse samples. Here, confronting with single-molecule imaging this common but poorly understood situation,… [Phys. Rev. Lett. 129, 147801] Published Wed Sep 28, 2022

Author(s): Austin Hopkins, Michael Chiang, Benjamin Loewe, Davide Marenduzzo, and M. Cristina Marchetti The rheology of biological tissue plays an important role in many processes, from organ formation to cancer invasion. Here, we use a multiphase field model of motile cells to simulate active microrheology within a tissue monolayer. When unperturbed, the tissue exhibits a transition between a solidli… [Phys. Rev. Lett. 129, 148101] Published...

Author(s): Fabian Jan Schwarzendahl and Hartmut Löwen The phenomenon that a system at a hot temperature cools faster than at a warm temperature, referred to as the Mpemba effect, has recently been realized for trapped colloids. Here, we investigate the cooling and heating process of a self-propelled active colloid using numerical simulations and theore… [Phys. Rev. Lett. 129, 138002] Published Fri Sep 23, 2022

Author(s): Agnese Codutti, Jonas Cremer, and Karen Alim Fluid dynamics simulations suggest that the varying flow speed inside the small intestine maximizes nutrient absorption while minimizing excess bacteria. [Phys. Rev. Lett. 129, 138101] Published Fri Sep 23, 2022

Author(s): Kaili Xie, Benjamin Gorin, Rory T. Cerbus, Laura Alvarez, Jean-Michel Rampnoux, and Hamid Kellay Here we show that encapsulating active Janus particles within a drop renders it more resistant to deformation. This drop is deformed under the action of an extensional flow. Such deformation is primarily resisted by the drop interfacial tension. When the particles are active under the action of lase… [Phys.

Author(s): Alexandra Lamtyugina, Yuqing Qiu, Étienne Fodor, Aaron R. Dinner, and Suriyanarayanan Vaikuntanathan Biological materials, such as the actin cytoskeleton, exhibit remarkable structural adaptability to various external stimuli by consuming different amounts of energy. In this Letter, we use methods from large deviation theory to identify a thermodynamic control principle for structural transitions i… [Phys. Rev. Lett. 129, 128002...

Author(s): Saroj Kumar Nandi, Daniel Österle, Meta Heidenreich, Emmanuel D. Levy, and Samuel A. Safran Biomolecular self-assembly spatially segregates proteins with a limited number of binding sites (valence) into condensates that coexist with a dilute phase. We develop a many-body lattice model for a three-component system of proteins with fixed valence in a solvent. We compare the predictions of th… [Phys. Rev. Lett. 129, 128102] Published...
