Local immunodeficiency: Minimal networks and stability [PDF]
Mathematical Biosciences, 2019 Some basic aspects of the recently discovered phenomenon of local immunodeficiency \cite{pnas} generated by antigenic cooperation in cross-immunoreactivity (CR) networks are investigated. We prove that local immunodeficiency (LI) that's stable under perturbations already occurs in very small networks and under general conditions on their parameters ...

Analysis of the Convergence and Periodicity of a Rational Difference Equation
Journal of Mathematical Sciences and Modelling, 2019 The exact solutions of most difference equations cannot be obtained sometimes. This can be attributed to the fact that there is no a specific approach from which one can find the exact solution.

Controlling Pest by Integrated Pest Management: A Dynamical Approach [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2020 Integrated Pest Management technique is used to formulate a mathematical model by using biological and chemical control impulsively. The uniform boundedness and the existence of pest extinction and nontrivial equilibrium points is discussed.

Relative Stability and Local Curvature Analysis in Carbon Nanotori [PDF]
, 2015 We introduce a concise formalism to characterize nanometer-sized tori based on carbon nanotubes and to determine their stability by combining {\em ab initio} density functional calculations with a continuum elasticity theory approach that requires only ...

On Fractional-Order Discrete-Time Reaction Diffusion Systems
Mathematics, 2023 Reaction–diffusion systems have a broad variety of applications, particularly in biology, and it is well known that fractional calculus has been successfully used with this type of system.

Many-body localization: stability and instability [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2017 Rare regions with weak disorder (Griffiths regions) have the potential to spoil localization. We describe a non-perturbative construction of local integrals of motion (LIOMs) for a weakly interacting spin chain in one dimension, under a physically reasonable assumption on the statistics of eigenvalues.
