Effect of Spatially Heterogeneous Mucin Coverage on Tear Film Stability and Ruptur
Deepak Kumar, Pushpavanam S
Clinical observations of dry eyes reveal that tear film breakup is associated with spatial variations in corneal wettability arising from non-uniform mucin coverage. Motivated by t…
A Reaction-Advection-Diffusion Model to describe Non-Uniformities in Colorimetric Sensing using Thin Porous Substrates
Kulkarni Namratha, S. Pushpavanam
Non-uniform product (color) distribution in colorimetric paper-based sensors affects the accuracy and reliability of measurements. The underlying mechanisms responsible for this ar…
Effect of Magnetic Field on Aqueous Humor Flows Inside Anterior Chamber of Human Eye
Deepak Kumar, Subramaniam Pushpavanam
Aqueous humor (AH) dynamics is responsible for maintaining intraocular pressure, ocular health and targeted drug delivery within the eye. This study investigates the flow of AH wit…
A framework to identify supercritical and subcritical Turing bifurcations: Case study of a system sustaining cubic and quadratic autocatalysis
Deepak Kumar, Subramaniam Pushpavanam
In this work, we focus on an autocatalytic reaction-diffusion model and carry out multiple scale weakly nonlinear analysis. A cubic and a quadratic autocatalytic reaction system is…
