Oscillation and asymptotic behavior of bounded solutions of functional differential equations with delay

Journal of Mathematical Analysis and Applications, 1983
AbstractConditions on a(t), g(t), and f(t) have been found under which the bounded nonoscillatory solutions of the equation y(n)(t) − a(t) y(g(t)) = f(t) approach zero. For the even order equation y(2n)(t) − a(t) y(g(t)) = f(t) the delay is shown to be causing the oscillatory behavior.

Within‐Host Mathematical Modeling of Antibiotic‐phage Treatments on Lysogenic and Nonlysogenic Bacteria Dynamics

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT Bacteriophages, or phages (viruses of bacteria), play significant roles in shaping the diversity of bacterial communities within the human gut. A phage‐infected bacterial cell can either immediately undergo lysis (virulent/lytic infection) or enter a stable state within the host as a prophage (lysogeny) until a trigger event, called prophage ...

Absence of Floquet scattering in oscillating non-Hermitian potential wells

, 2013
Scattering of a quantum particle from an oscillating barrier or well does not generally conserve the particle energy owing to energy exchange with the photon field, and an incoming particle-free state is scattered into a set of outgoing (transmitted and ...

Stability and Hopf Bifurcations Analysis in a Three‐Phase Dengue Diffusion Model With Time Delay in Fractional Derivative and Laplace–Adomian Decomposition Numerical Approach

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This study examines the complex dynamics of dengue transmission by incorporating time delay into a comprehensive model. The model is designed to capture several essential components, including steady‐state events, immune waning, recuperation from infection, and partial shielding in human populations.

From heaviness to lightness during inflation

, 2004
We study the quantum fluctuations of scalar fields with a variable effective mass during an inflationary phase. We consider the situation where the effective mass depends on a background scalar field, which evolves during inflation from being frozen into

Homogenization of Solute Transport in Double Porosity Materials

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We propose a novel model for the transport of solute in a vascularized poroelastic material. Our structure comprises a poroelastic matrix with an embedded connected fluid compartment, and we consider a solute transported between the two subdomains.

Quantum Parametric Resonance of a dissipative oscillator: fading and persistent memory in the long-time evolution [PDF]

arXiv, 2019
The evolution of a quantum oscillator, with periodically varying frequency and damping, is studied in the two cases of parametric resonance (PR) producing a limited, or unlimited stretching of the wave function. The different asymptotic behaviors of the energy distribution, show the non trivial interplay between PR and the initial quantum state. In the

Timelike form factors at high energy

, 1994
The difference between the timelike and spacelike meson form factors is analysed in the framework of perturbative QCD with Sudakov effects included. It is found that integrable singularities appear but that the asymptotic behavior is the same in the ...

Nonlocal Cooperative Behavior, Psychological Effects, and Collective Decision‐Making: An Exemplification With Predator–Prey Models

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In bio‐social models, cooperative behavior has evolved as an adaptive strategy, playing multi‐functional roles. One of such roles in populations is to increase the success of the survival and reproduction of individuals and their families or social groups.
