A new type of identification problems: optimizing the fractional order in a nonlocal evolution equation [PDF]

open access: yes, 2016
In this paper, we consider a rather general linear evolution equation of fractional type, namely a diffusion type problem in which the diffusion operator is the $s$th power of a positive definite operator having a discrete spectrum in $\R^+$.

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 ...

Novel Dynamic Structures of 2019-nCoV with Nonlocal Operator via Powerful Computational Technique

open access: yesBiology, 2020
In this study, we investigate the infection system of the novel coronavirus (2019-nCoV) with a nonlocal operator defined in the Caputo sense. With the help of the fractional natural decomposition method (FNDM), which is based on the Adomian decomposition

Construction of stochastic hybrid path integrals using operator methods [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2020
Stochastic hybrid systems involve the coupling between discrete and continuous stochastic processes. They are finding increasing applications in cell biology, ranging from modeling promoter noise in gene networks to analyzing the effects of ...

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 ...

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.

The role of costimulatory molecules in glioma biology and immune microenvironment

open access: yesFrontiers in Genetics, 2022
Background: Extensive research showed costimulatory molecules regulate tumor progression. Nevertheless, a small amount of literature has concentrated on the potential prognostic and therapeutic effects of costimulatory molecules in patients with glioma ...

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 ...
