Nonlinear interaction between dynamo-generated magnetic fields, mean flows and internal gravity waves in stellar stably-stratified layers: From 3D to 1D

This paper presents a 1D mean-field model that integrates 3D-derived dynamo coefficients to demonstrate how nonlinear interactions between dynamo-generated magnetic fields and internal gravity waves create new dynamical regimes, such as magnetic perturbations of shear layer oscillations, which significantly influence angular momentum transport and the long-term rotational evolution of stellar radiative interiors.

Evanescent and inertial-like waves in rigidly-rotating odd viscous liquids

This paper demonstrates that rigidly rotating odd viscous liquids support a diverse spectrum of non-axisymmetric oscillatory, evanescent, and mixed-type inertial-like waves, the classification and precession characteristics of which offer a pathway to experimentally determine odd viscosity coefficients while establishing a formal equivalence between two- and three-dimensional formulations.

Universal behavior in traveling wave electroosmosis

This paper establishes a unified theoretical framework for traveling wave electroosmosis that explains the emergence of a unidirectional zero-mode velocity through symmetry-breaking nonlinearities, demonstrating self-similar velocity profiles and providing universal relations to predict transport in thin capillaries without the need for repeated experiments.

Aging in the Flow Dynamics of Dense Suspensions of Contactless Microparticles

This study reveals that dense suspensions of contactless silica microparticles exhibit an aging phenomenon where longer resting periods logarithmically delay flow onset and reduce velocity by progressively stabilizing the system through thermal fluctuations, independent of packing fraction changes or crystallization.

Oscillating electroosmotic flow in channels and capillaries with modulated wall charge distribution

This paper demonstrates that applying an alternating electric field to electrolyte-filled channels with modulated wall charge generates oscillating laminar flows and vortices with circulation dependent on the oscillation period, revealing a frequency- and viscosity-dependent "memory retention time" that enables control over signal carriers despite vanishing mass flux.

Dancing rivulets in an air-filled Hele-Shaw cell

This paper investigates the nonlinear instability of a thin fluid rivulet in an air-filled Hele-Shaw cell under external acoustic forcing, revealing that a three-wave resonant interaction drives the formation of a specific spatiotemporal pattern whose mode selection and threshold are successfully predicted by a depth-averaged Navier-Stokes model.

Characterisations for the depletion of reactant in a one-dimensional dynamic combustion model

This paper establishes that for a one-dimensional compressible Navier-Stokes combustion model with discontinuous reaction rates, the reactant mass fraction satisfies a weighted gradient estimate preventing cusp formation and ensuring bounded entropy, provided the initial density is Lipschitz continuous and strictly bounded away from zero and infinity.

Nonlinear dynamics of air invasion in one-dimensional compliant fluid networks

Inspired by plant embolism, this study reveals that air invasion in compliant one-dimensional fluid networks is governed by a nonlinear feedback between pressure diffusion and pervaporation timescales, leading to complex, history-dependent dynamics that inform both biological understanding and soft microfluidic design.

An efficient implicit scheme for the multimaterial Euler equations in Lagrangian coordinates

This paper presents an efficient implicit numerical scheme for solving multimaterial Euler equations in Lagrangian coordinates, which overcomes stringent time step restrictions in high-density-ratio stratified flows by reducing the problem to a single symmetric positive definite wave equation for pressure while incorporating filtering strategies to suppress oscillations.

A Hybrid semi-Lagrangian Flow Mapping Approach for Vlasov Systems: Combining Iterative and Compositional Flow Maps

This paper proposes a hybrid semi-Lagrangian scheme for the Vlasov-Poisson equation that synergistically combines the Numerical Flow Iteration (NuFI) method's conservative local time-stepping with the Characteristic Mapping Method's (CMM) efficient global submap composition to achieve a balance between computational cost, storage requirements, and structural preservation.
