On a Nonlinear Coupled Fractional Differential System With Multiderivative‐Terms and Coupled Closed Boundary Data

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This article is devoted to the study of existence, uniqueness, and Ulam–Hyers stability for a coupled system of two nonlinear Caputo‐type multiterm fractional differential equations equipped with coupled closed boundary data. The concept of coupled closed boundary conditions finds its applications in several physical situations, like composite panels ...

Multiscale Coupling Between Macroscopic Mechanics and Atomic Assembly (MM–AA) of Soft‐Lattice Halide Perovskites

Aggregate, Volume 6, Issue 11, November 2025.
This review clarifies the multiscale coupling mechanisms between macroscopic mechanics (e.g., surface tension, fluid shear, interfacial stress) and atomic assembly, highlighting the importance of mechanical regulation in suppressing solute aggregation and guiding crystal orientation.

A note on “Taylor–Couette flow of a generalized second grade fluid due to a constant couple”

Nonlinear Analysis, 2010
In this brief note, we show that the unsteady flow of a generalized second grade fluid due to a constant couple, as well as the similar flow of Newtonian and ordinary second grade fluids, ultimately becomes steady.

Numerical Investigation of Turbulent Mixed Convection Between Coaxial Cylinders and the Inner Rotating Cylinder With Axial Flow

Energy Science &Engineering, Volume 13, Issue 11, Page 5133-5153, November 2025.
ABSTRACT The turbulent flow between coaxial cylinders, particularly when the inner cylinder is rotating, exhibits complex hydrodynamic and heat transfer behaviors critical for various engineering applications. Although many previous studies have simplified these systems with idealized assumptions, real‐world scenarios involve mixed convection and ...

Coupling 3D Geodynamics and Dynamic Rupture: Rheology and Stress Control on Strike‐Slip Fault Evolution and Earthquake Dynamics

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 9, September 2025.
Abstract Tectonic deformation shapes the Earth's surface, with strain localization resulting in the formation of shear zones and faults that accommodate significant tectonic displacement. Earthquake dynamic rupture models, which provide valuable insights into earthquake mechanics and seismic ground motions, rely on initial conditions such as pre‐stress

Interfacial Yield Stress Response in Synthetic Mucin Solutions

Advanced Materials Interfaces, Volume 12, Issue 12, June 23, 2025.
The solution rheology of novel synthetic mucins mimicking natural mucin domains is studied. Like many natural mucin solutions, apparent solid‐like rheology is seen. However, no bulk structural features are found to explain it. Interfacial rheology and robust modelling reveal that this arises from molecular associations at the air–water interface ...
