Bioluminescence in turbulence: intermittent straining lights up dinoflagellates
Praphul Kumar, Jason R. Picardo
Dinoflagellates are marine phytoplankton that emit flashes of light in response to flow-induced deformation; they are responsible for illuminating breaking-waves, wakes of ships, a…

Tunability of Dissipative Particle Dynamics simulations for Excluded Volume and Hydrodynamic Interactions in polymer solutions and Rheological predictions
Sanjay Jana, Venkata Siva Krishna, Praphul Kumar +1
Even though the Dissipative Particle Dynamics (DPD) has shown its worth in a variety of research areas, it has been rarely used for polymer dynamics, particularly in dilute and sem…

Gravity modes on rapidly rotating accreting white dwarfs and their variation after dwarf novae
Praphull Kumar, Dean M. Townsley
Accreting white dwarfs in Cataclysmic variables (CVs) show short-period (tens of minutes) brightness variations that are consistent with non-radial oscillations similar to gravity…
