Multi-input regulation and logic with T7 promoters in cells and cell-free systems. [PDF]

open access: yesPLoS ONE, 2013
Engineered gene circuits offer an opportunity to harness biological systems for biotechnological and biomedical applications. However, reliance on native host promoters for the construction of circuit elements, such as logic gates, can make the ...

Non-linear eigenvalue problems arising from growth maximization of positive linear dynamical systems [PDF]

open access: yes, 2014
We study a growth maximization problem for a continuous time positive linear system with switches. This is motivated by a problem of mathematical biology (modeling growth-fragmentation processes and the PMCA protocol).

Schauder a priori estimates and regularity of solutions to boundary-degenerate elliptic linear second-order partial differential equations [PDF]

open access: yes, 2013
We establish Schauder a priori estimates and regularity for solutions to a class of boundary-degenerate elliptic linear second-order partial differential equations.

Operations Research Tools for Biology

open access: yes, 2023
This thesis shows how to use Operations Research tools, e.g. Markov chains, optimization, game theory, and matchings, to understand problems that appear in biological contexts. We focus on two biological systems – the activation of the immune system in response to pathogens, and the metabolism of communities of different species of microbes. In Chapter

Resolvent Positive Linear Operators Exhibit the Reduction Phenomenon [PDF]

open access: yes, 2011
The spectral bound, s(a A + b V), of a combination of a resolvent positive linear operator A and an operator of multiplication V, was shown by Kato to be convex in b \in R.

On Regularly Varying and History-Dependent Convergence Rates of Solutions of a Volterra Equation with Infinite Memory

open access: yesAdvances in Difference Equations, 2010
We consider the rate of convergence to equilibrium of Volterra integrodifferential equations with infinite memory. We show that if the kernel of Volterra operator is regularly varying at infinity, and the initial history is regularly varying at minus ...

Shaping Pulses to Control Bistable Monotone Systems Using Koopman Operator [PDF]

open access: yes, 2016
In this paper, we further develop a recently proposed control method to switch a bistable system between its steady states using temporal pulses. The motivation for using pulses comes from biomedical and biological applications (e.g.
