A Semi‐Discrete Lagrangian‐Eulerian Numerical Scheme for Diffusive‐Dispersive Conservation Laws With Discontinuous Coefficient

Numerical Methods for Partial Differential Equations, Volume 42, Issue 5, September 2026.
ABSTRACT In this work, we present an extension of the semi‐discrete Lagrangian‐Eulerian numerical scheme for diffusive‐dispersive conservation law problems, including a jump discontinuous flux function. As in the one‐dimensional scalar hyperbolic case, the no‐flow curves also organize the geometry of the method.

Collisionless Shocks: Contemporary State After Three Quarters of a Century of Research

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract The collisionless shock research started in the late 1950s. Since then, plenty of data have been accumulated due to the large number of missions in the heliosphere, providing in situ measurements of the fields and particles. The quality of these measurements has vastly improved, especially in the last two decades.

Structured Energy Conversion in Kelvin‐Helmholtz Instability

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract We present quantitative investigations of the energy conversion pathways—electromagnetic ϵEM $\left({{\epsilon}}^{EM}\right)$, fluid flow ϵf $\left({{\epsilon}}^{f}\right)$, and particle thermal ϵth $\left({{\epsilon}}^{th}\right)$ energies—within the Kelvin‐Helmholtz instability (KHI) observed by the Magnetospheric Multiscale mission. We find

Toward Intelligent Multimodal Holography for Real‐Time Chemical Imaging of Dynamic Ion Separation

Advanced Intelligent Discovery, Volume 2, Issue 4, August 2026.
Intelligent multimodal holography integrates digital off‐axis holography, spectroscopic imaging, and AI‐driven reconstruction to visualize ion transport and chemical dynamics in real time. In this perspective paper, we outline how this approach enables label‐free, chemically specific monitoring of complex environments and discuss its potential to ...

MHD Heat Transfer Enhancement in TiO2‐Fe3O4/Water Hybrid Nanofluid Over a Porous Stretching/Shrinking Surface With Suction/Injection and Heat Source Effects

Engineering Reports, Volume 8, Issue 8, August 2026.
Magnetohydrodynamic flow of TiO2‐Fe3O4/water hybrid nanofluid over a porous stretching/shrinking surface enhances heat transfer under Joule heating and radiation effects. Thermal performance improves with nanoparticle concentration and Eckert number, while suction reduces heat transport, highlighting its potential for advanced industrial cooling ...

Modeling and Analysis of Nonlinear Radiative and Electromagnetic Effects With Second‐Order Slip in Unsteady Hybrid Nanofluid Flow Past a Porous Stretching Surface

Engineering Reports, Volume 8, Issue 8, August 2026.
The current work examines the dynamics of the stagnation point flow of an unsteady hybrid nanofluid (Fe2O3–Cu/H2O) across an inclined porous stretching surface. It considers heat transfer, second‐order slip, electrical field, heat source/sink, mixed convection, and magnetic field effects, as well as linear and nonlinear radiation.

Magnetic Vestibular Stimulation in Subjects with Unilateral Labyrinthine Disorders

Frontiers in Neurology, 2014
We recently discovered that static magnetic fields from high-strength MRI machines induce nystagmus in all normal humans, and that a magnetohydrodynamic (MHD) Lorentz force, derived from ionic currents in the endolymph and pushing on the cupula, best ...
