Stability of Viscous Three‐Dimensional Stratified Couette Flow via Dispersion and Mixing

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT This article explores the stability of stratified Couette flow in the viscous 3d$3d$ Boussinesq equations. In this system, mixing effects arise from the shearing background, and gravity acts as a restoring force leading to dispersive internal gravity waves.

Plasmakristall‐4 Experiment: 10 Years of Operation in Orbit

Contributions to Plasma Physics, EarlyView.
ABSTRACT Plasmakristall‐4 (PK‐4) is a microgravity complex plasma laboratory operated for 10 years on board the International Space Station. Its main purpose is the particle‐resolved investigation of generic condensed matter phenomena using strongly coupled suspensions of microparticles immersed in low‐pressure gas‐discharge plasmas.

Streamlines in stationary homogeneous isotropic turbulence and fractal-generated turbulence [PDF]

Fluid Dynamics Research, 2016
We compare streamline statistics in stationary homogeneous isotropic turbulence and in turbulence generated by a fractal square grid. We examine streamline segments characterised by the velocity difference and the distance l between extremum points. We find close agreement between the stationary homogeneous isotropic turbulence and the decay region of ...

Fractional Moment Theory for Anomalous Transport: A Unified Framework for Lévy Flights, Fractals, and Complex Dynamical Systems

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We develop a unified mathematical framework extending classical moment theory from discrete integer orders to a continuous spectrum of real orders f>0$$ f>0 $$, providing a systematic statistical characterization of complex systems exhibiting power‐law behavior.

Local Chemical Gradients in a Mammalian Cortex Measured In Vivo With a Silicon Nanodialysis Mass Spectrometry Platform

Angewandte Chemie, Volume 138, Issue 26, 22 June 2026.
Fluorescence image of the coronal slice of mouse brain where multiple neurochemicals have been measured in vivo with a nanodialysis platform coupled to CE‐MS to reveal strong millimeter‐scale spatial chemical gradients. Formation and maintenance of such local chemical compartments in the otherwise diffusion‐homogeneous cortex indicates strong ...

Assessing and Quantifying Variability Across Vacuum‐Assisted Resin Infusion Variants for Aerospace‐Grade Composite Manufacturing

Polymer Composites, EarlyView.
Radar‐plot comparison of consolidation quality and flexural performance of composite laminates manufactured by six vacuum‐infusion routes, evaluated at the resin‐inlet and vacuum‐port regions. ABSTRACT Conventional vacuum‐assisted resin transfer molding (C‐VARTM) is recognized as a cost‐effective resin infusion technique for manufacturing large‐scale ...

Formation of Fine Structures in Incompressible Hall Magnetohydrodynamic Turbulence Simulations

Plasma
Hall magnetohydrodynamic simulations are often carried out to study the subjects of instabilities and turbulence of space and nuclear fusion plasmas in which sub-ion-scale effects are important.

Determination of the decay exponent in mechanically stirred isotropic turbulence

AIP Advances, 2011
Direct numerical simulation is used to investigate the decay exponent of isotropic homogeneous turbulence over a range of Reynolds numbers sufficient to display both high and low Re number decay behavior.

Scaling of Lyapunov exponents in homogeneous isotropic turbulence

Physical Review Fluids, 2017
Lyapunov exponents measure the average exponential growth rate of typical linear perturbations in a chaotic system, and the inverse of the largest exponent is a measure of the time horizon over which the evolution of the system can be predicted. Here, Lyapunov exponents are determined in forced homogeneous isotropic turbulence for a range of Reynolds ...
