Exponential Energy Decay of Solutions for a Transmission Problem With Viscoelastic Term and Delay

open access: yesMathematics, 2016
In our previous work (Journal of Nonlinear Science and Applications 9: 1202–1215, 2016), we studied the well-posedness and general decay rate for a transmission problem in a bounded domain with a viscoelastic term and a delay term.

Soft, Dynamic Hydrogel Confinement Improves Kidney Organoid Lumen Morphology and Reduces Epithelial–Mesenchymal Transition in Culture

open access: yesAdvanced Science, 2022
Pluripotent stem cell‐derived kidney organoids offer a promising solution to renal failure, yet current organoid protocols often lead to off‐target cells and phenotypic alterations, preventing maturity.

Blow-up of solutions to a viscoelastic parabolic equation with positive initial energy

open access: yesBoundary Value Problems, 2017
In this paper, a semilinear viscoelastic parabolic equation with nonlinear boundary flux is studied. Due to the comparison principle being invalid, potential well method and concavity argument are used to prove that the solutions blow up in finite time ...

Membrane viscoelasticity

open access: yesBiophysical Journal, 1976
In this paper, we develop a theory for viscoelastic behavior of large membrane deformations and apply the analysis to the relaxation of projections produced by small micropipette aspiration of red cell discocytes. We show that this relaxation is dominated by the membrane viscosity and that the cytoplasmic and extracellular fluid flow have negligible ...

Viscoelastic properties of MR shear thickening fluids

open access: yesJournal of Fluid Science and Technology, 2014
Magento-rheological Fluid (MRF) and Shear Thickening Fluid (STF) have separately attracted considerable interest due to their fast and reversible response to an external magnetic field or an abrupt shearing loading. In this paper we fabricated a combined

A Viscoelastic Catastrophe

open access: yesCoRR, 2018
We use a differential constitutive equation to model the flow of a viscoelastic flow in a cross-slot geometry, which is known to exhibit bistability above a critical flow rate. The novelty lies in two asymmetric modifications to the geometry, which causes a change in the bifurcation diagram such that one of the stable solutions becomes disconnected ...

Application of Piezo-Based Measuring System for Evaluation of Nucleic Acid-Based Drugs Influencing the Coagulation

open access: yesSensors, 2019
During open-heart surgery, the status of hemostasis has to be constantly monitored to quickly and reliably detect bleeding or coagulation disorders.

Viscoelasticity Measurement and Identification of Viscoelastic Parametric Models

open access: yesVolume 1: 23rd Biennial Conference on Mechanical Vibration and Noise, Parts A and B, 2011
Generally speaking, the behaviour of viscoelastic material is more complicated than the behaviour proposed by classical models as Voigt, Maxwell or Zener. The stiffness of such materials is a frequency dependent complex function. Above 1000Hz, classical measurements techniques are unable to achieve accurate measurements of the stiffness. In this paper,

Viscoelastic properties of crystals [PDF]

open access: yesThe Journal of Chemical Physics, 2009
We examine the question of whether fluids and crystals are differentiated on the basis of their zero frequency shear moduli or their limiting zero frequency shear viscosity. We show that while fluids, in contrast with crystals, do have a zero value for their shear modulus, in contradiction to a widespread presumption, a crystal does not have an ...
