Many-body microhydrodynamics of colloidal particles with active boundary layers
Rajesh Singh, Somdeb Ghose, R. Adhikari
Colloidal particles with active boundary layers - regions surrounding the particles where nonequilibrium processes produce large velocity gradients - are common in many physical, c…
Irreducible Representations Of Oscillatory And Swirling Flows In Active Soft Matter
Somdeb Ghose, R. Adhikari
Recent experiments imaging fluid flow around swimming microorganisms have revealed complex time-dependent velocity fields that differ qualitatively from the stresslet flow commonly…
Hydrodynamic Instabilities Provide A Generic Route To Spontaneous Biomimetic Oscillations In Chemomechanically Active Filaments
Abhrajit Laskar, Rajeev Singh, Somdeb Ghose +3
Non-equilibrium processes which convert chemical energy into mechanical motion enable the motility of organisms. Bundles of inextensible filaments driven by energy transduction of…
Autonomous Motility of Active Filaments due to Spontaneous Flow-Symmetry Breaking
Gayathri Jayaraman, Sanoop Ramachandran, Somdeb Ghose +4
We simulate the nonlocal Stokesian hydrodynamics of an elastic filament which is active due a permanent distribution of stresslets along its contour. A bending instability of an in…
Non-renewal statistics in the catalytic activity of enzyme molecules at mesoscopic concentrations
Soma Saha, Somdeb Ghose, R. Adhikari +1
Recent fluorescence spectroscopy measurements of single-enzyme kinetics have shown that enzymatic turnovers form a renewal stochastic process in which the inverse of the mean waiti…
Endogenous Quasicycles and Stochastic Coherence in a Closed Endemic Model
Somdeb Ghose, R. Adhikari
We study the role of demographic fluctuations in typical endemics as exemplified by the stochastic SIRS model. The birth-death master equation of the model is simulated using exact…
