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.

On the Use of Adaptive Resemblance Terms in Chemical Ecology

open access: yesPsyche: A Journal of Entomology, 2012
Many organisms (mimics) show adaptive resemblance to an element of their environment (model) in order to dupe another organism (operator) for their own benefit.

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 ...

Fraction-of-Time Probability: Advancing Beyond the Need for Stationarity and Ergodicity Assumptions

open access: yesIEEE Access, 2022
Time series arising from measurements in many fields of physics, engineering, chemistry, biology, and econometrics, are commonly modeled as sample paths from an ensemble which, together with a probability measure, is called a stochastic process ...

Rigorous elimination of fast stochastic variables from the linear noise approximation using projection operators [PDF]

open access: yes, 2012
The linear noise approximation (LNA) offers a simple means by which one can study intrinsic noise in monostable biochemical networks. Using simple physical arguments, we have recently introduced the slow-scale LNA (ssLNA) which is a reduced version of ...

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

Man-Machine-Environment Virtual Design and JACK Simulation of Rosa Roxburghii Picking Machine [PDF]

open access: yesE3S Web of Conferences, 2020
In order to improve the coordination between human and agricultural machinery, taking Rosa roxburghii picking machine as an example, a virtual design method based on human-machine-environment system, combined with three-dimensional digital simulation ...
