Active dynamics of charged macromolecules
Tapas Singha, Siao-Fong Li, Murugappan Muthukumar
We study the role of active coupling on the transport properties of homogeneously charged macromolecules in an infinitely dilute solution. An enzyme becomes actively bound to a seg…
Contractility-driven cell motility against a viscoelastic resistance
Tapas Singha, Pierre Sens
We study a model of contraction-based cell motility inside a microchannel to investigate the regulation of cell polarization and motion by the mechanical resistance of the environm…
Mean first passage time of active fluctuating membrane with stochastic resetting
Tapas Singha
We study the mean first passage time of a one-dimensional active fluctuating membrane that is stochastically returned to the same flat initial condition at a finite rate. We start…
Clustering of lipids driven by integrin
Tapas Singha, Anirban Polley, Mustansir Barma
Integrin is an important transmembrane receptor protein which remodels the actin network and anchors the cell membrane towards the extracellular matrix via mechanochemical pathways…
Fixation in Competing Populations: Diffusion and Strategies for Survival
Tapas Singha, Prasad Perlekar, Mustansir Barma
How should dispersal strategies be chosen to increase the likelihood of survival of a species? We obtain the answer for the spatially extended versions of three well-known models o…
Clustering, intermittency and scaling for passive particles on fluctuating surfaces
Tapas Singha, Mustansir Barma
We show that a scaling approach successfully characterizes clustering and intermittency in space and time, in systems of noninteracting particles driven by fluctuating surfaces. We…
