Phase-field Model for Vesicle Hydrodynamics in Viscoelastic Fluids

Published:Dec 29, 2025 09:07
1 min read
ArXiv

Analysis

This paper presents a computational model for simulating the behavior of multicomponent vesicles (like cell membranes) in complex fluid environments. Understanding these interactions is crucial for various biological processes. The model incorporates both the fluid's viscoelastic properties and the membrane's composition, making it more realistic than simpler models. The use of advanced numerical techniques like RBVMS, SUPG, and IGA suggests a focus on accuracy and stability in the simulations. The study's focus on shear and Poiseuille flows provides valuable insights into how membrane composition and fluid properties affect vesicle behavior.
Reference

“The model couples a fluid field comprising both Newtonian and Oldroyd-B fluids, a surface concentration field representing the multicomponent distribution on the vesicle membrane, and a phase-field variable governing the membrane evolution.”

Diffusion wave phenomena and optimal time decay for incompressible viscoelastic flows

Published:Dec 28, 2025 13:21
1 min read
ArXiv

Analysis

This article likely presents research on the mathematical properties of viscoelastic fluids. The title suggests an investigation into how disturbances (waves) propagate within these fluids and how their effects diminish over time (decay). The terms 'incompressible' and 'optimal' indicate specific constraints and goals of the study, likely aiming to establish theoretical bounds or understand the behavior of these flows under certain conditions.

Stable Numerical Methods for Viscoelastic Giesekus Model

Published:Dec 28, 2025 08:10
1 min read
ArXiv

Analysis

This paper addresses the challenges of numerically solving the Giesekus model, a complex system used to model viscoelastic fluids. The authors focus on developing stable and convergent numerical methods, a significant improvement over existing methods that often suffer from accuracy and convergence issues. The paper's contribution lies in proving the convergence of the proposed method to a weak solution in two dimensions without relying on regularization, and providing an alternative proof of a recent existence result. This is important because it provides a reliable way to simulate these complex fluid behaviors.
Reference

“The main goal is to prove the (subsequence) convergence of the proposed numerical method to a large-data global weak solution in two dimensions, without relying on cut-offs or additional regularization.”

Epigenetic State Controls Chromatin Mechanics

Published:Dec 28, 2025 07:15
1 min read
ArXiv

Analysis

This paper investigates the relationship between epigenetic marks, 3D genome organization, and the mechanical properties of chromatin. It develops a theoretical framework to infer locus-specific viscoelasticity and finds that chromatin's mechanical behavior is heterogeneous and influenced by epigenetic state. The findings suggest a mechanistic link between chromatin mechanics and processes like enhancer-promoter communication and response to cellular stress, opening avenues for experimental validation.
Reference

“Chromatin viscoelasticity is an organized, epigenetically coupled property of the 3D genome.”

Magnetic Drop Targeting for Retinal Detachment Treatment

Published:Dec 27, 2025 09:39
1 min read
ArXiv

Analysis

This paper explores a novel approach to treating retinal detachment using magnetic fields to guide ferrofluid drops. It's significant because it models the complex 3D geometry of the eye and the viscoelastic properties of the vitreous humor, providing a more realistic simulation than previous studies. The research focuses on optimizing parameters like magnetic field strength and drop properties to improve treatment efficacy and minimize stress on the retina.
Reference

“The results reveal that, in addition to the magnetic Bond number, the ratio of the drop-to-VH magnetic permeabilities plays a key role in the terminal shape parameters, like the retinal coverage.”
