Steady solution and its stability of a mathematical model of diabetic atherosclerosis [PDF]

open access: yesJournal of Biological Dynamics, 2023
Atherosclerosis is a leading cause of death worldwide. Making matters worse, nearly 463 million people have diabetes, which increases atherosclerosis-related inflammation. Diabetic patients are twice as likely to have a heart attack or stroke.

Convergence rate for the incompressible limit of nonlinear diffusion–advection equations [PDF]

open access: yesAnnales de l'Institut Henri Poincare. Analyse non linéar, 2021
The incompressible limit of nonlinear diffusion equations of porous medium type has attracted a lot of attention in recent years, due to its ability to link the weak formulation of cell-population models to free boundary problems of Hele-Shaw type ...

On the number of positive solutions to an indefinite parameter-dependent Neumann problem [PDF]

open access: yes, 2021
We study the second-order boundary value problem { −u′′ = aλ,μ(t)u(1− u), t ∈ (0, 1), u′(0) = 0, u′(1) = 0, where aλ,μ is a step-wise indefinite weight function, precisely aλ,μ ≡ λ in [0, σ]∪ [1−σ, 1] and aλ,μ ≡ −μ in (σ, 1−σ), for some σ ∈ ( 0, 1 2 ...

Quantitative mean-field limit for interacting branching diffusions [PDF]

open access: yesElectronic Journal of Probability, 2021
We establish an explicit rate of convergence for some systems of meaneld interacting di usions with logistic binary branching towards the solutions of nonlinear evolution equations with non-local self-di usion and logistic mass growth, shown to describe ...

Study of nanolayer on red blood cells as drug carrier in an artery with stenosis

open access: yesComputational and Mathematical Biophysics, 2023
This article discusses a novel idea from cell therapy in which nanoparticles (NPs) are adsorbed on red blood cells (RBCs). RBCs serve as a drug carrier for NPs or nanodrugs adsorbed on the cell membrane of RBC.

Global existence and boundedness in a two-species chemotaxis system with nonlinear diffusion

open access: yesOpen Mathematics, 2021
This paper is concerned with a chemotaxis system ut=Δum−∇⋅(χ1(w)u∇w)+μ1u(1−u−a1v),x∈Ω,t>0,vt=Δvn−∇⋅(χ2(w)v∇w)+μ2v(1−a2u−v),x∈Ω,t>0,wt=Δw−(αu+βv)w,x∈Ω,t>0,\left\{\begin{array}{ll}{u}_{t}=\Delta {u}^{m}-\nabla \cdot \left({\chi }_{1}\left(w)u\nabla w)+{\mu

Global boundedness to a 3D chemotaxis-Stokes system with porous medium cell diffusion and general sensitivity

open access: yesAdvances in Nonlinear Analysis, 2022
In this article, we will develop an analytical approach to construct the global bounded weak solutions to the initial-boundary value problem of a three-dimensional chemotaxis-Stokes system with porous medium cell diffusion Δnm\Delta {n}^{m} for m≥6563m ...

Weak and stationary solutions to a Cahn–Hilliard–Brinkman model with singular potentials and source terms

open access: yesAdvances in Nonlinear Analysis, 2020
We study a phase field model proposed recently in the context of tumour growth. The model couples a Cahn–Hilliard–Brinkman (CHB) system with an elliptic reaction-diffusion equation for a nutrient.

Logistic damping effect in chemotaxis models with density-suppressed motility

open access: yesAdvances in Nonlinear Analysis, 2022
This paper is concerned with a parabolic-elliptic chemotaxis model with density-suppressed motility and general logistic source in an n-dimensional smooth bounded domain with Neumann boundary conditions.
