Increased myocardial stiffness more than impaired relaxation function limits cardiac performance during exercise in heart failure with preserved ejection fraction: a virtual patient study. [PDF]

Eur Heart J Digit Health, 2020
Aims The relative impact of left ventricular (LV) diastolic dysfunction (LVDD) and impaired left atrial (LA) function on cardiovascular haemodynamics in heart failure with preserved ejection fraction (HFpEF) is largely unknown.

Viscoelastic solids with unbounded relaxation function [PDF]

Continuum Mechanics and Thermodynamics, 1992
Linear viscoelastic solids are considered where the relaxation function is unbounded in that the initial value of the function and the derivative may be infinite but the function, freed from the equilibrium modulus, is integrable. The second law is given a general form for approximate cycles and then for cycles.

Holographic spectral functions with momentum relaxation [PDF]

Physical Review D, 2020
We study (fermionic) spectral functions in two holographic models, the Gubser-Rocha-linear axion model and the linear axion model, where translational symmetry is broken by axion fields linear to the boundary coordinates ($ _{I}= _{Ii} x^{i}$). Here, $ $ corresponds to the strength of momentum relaxation.

General decay rate of a weakly dissipative viscoelastic equation with a general damping [PDF]

Opuscula Mathematica, 2020
In this paper, we consider a weakly dissipative viscoelastic equation with a nonlinear damping. A general decay rate is proved for a wide class of relaxation functions. To support our theoretical findings, some numerical results are provided.

Global existence and new decay results of a viscoelastic wave equation with variable exponent and logarithmic nonlinearities

AIMS Mathematics, 2021
In this paper, we consider the following viscoelastic problem with variable exponent and logarithmic nonlinearities: $ u_{tt}-\Delta u+u+ \int_0^tb(t-s)\Delta u(s)ds+|u_t|^{{\gamma}(\cdot)-2}u_t = u\ln{\vert u\vert^{\alpha}}, $ where $ {\gamma}(.)

Uniform decay estimates for the semi-linear wave equation with locally distributed mixed-type damping via arbitrary local viscoelastic versus frictional dissipative effects

Advances in Nonlinear Analysis, 2023
We are concerned with the stabilization of the wave equation with locally distributed mixed-type damping via arbitrary local viscoelastic and frictional effects.

General decay for a system of viscoelastic wave equation with past history, distributed delay and Balakrishnan-Taylor damping terms

Electronic Research Archive, 2022
The subject of this research is a coupled system of nonlinear viscoelastic wave equations with distributed delay components, infinite memory and Balakrishnan-Taylor damping. Assume the kernels $ g_{i} :{\bf R}_{+}\rightarrow {\bf R}_{+} $ holds true the

Asymptotic stability of a quasi-linear viscoelastic Kirchhoff plate equation with logarithmic source and time delay

AIMS Mathematics, 2023
In this paper, a quasi-linear viscoelastic Kirchhoff plate equation with logarithmic source and time delay involving free boundary conditions in a bounded domain is considered. The local existence and global existence are proved, respectively.
