A Thermodynamic Framework for Turing‐Type Instabilities in Porous Media: Part II Applications

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Compaction bands, desiccation cracks, and melt segregation structures are geological patterns relying on the same fundamental manifestations of a universal Turing‐type instability mechanism, as predicted by the thermodynamically consistent reaction–cross‐diffusion framework developed in Part I (Regenauer‐Lieb et al., 2025, https://doi.org/10 ...

MMS Observation of Trapping of Electrons by Chorus Waves Inside a Magnetic Hole

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract We present an event of chorus waves embedded within a magnetic hole (MH) in the Earth's magnetosheath, observed by the Magnetospheric Multi‐Scale (MMS) mission on 1 March 2016. Unlike conventional cases where chorus waves are typically detected near the center of a magnetic depression, in this event lower‐band chorus waves appear predominantly

Two‐Dimensional Equilibrium Model of Planetary Magnetotail in Generalized Nonthermal Plasmas

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Solar wind‐magnetosphere interaction may result in an elongated magnetotail with stored magnetic field energy. This study presents for the first time a family of asymptotic solutions for stretched two‐dimensional magnetotail equilibrium in generalized nonthermal plasmas, including the Kappa‐like and Maxwellian‐like velocity distributions with ...

Unitary ensembles with a critical edge point, their multiplicative statistics, and the Korteweg‐de‐Vries hierarchy

Journal of the London Mathematical Society, Volume 113, Issue 3, March 2026.
Abstract We study the multiplicative statistics associated to the limiting determinantal point process describing eigenvalues of unitary random matrices with a critical edge point, where the limiting eigenvalue density vanishes like a power 5/2. We prove that these statistics are governed by the first three equations of the Korteweg‐de‐Vries (KdV ...

Toral symmetries of collapsed ancient solutions to the homogeneous Ricci flow

Journal of the London Mathematical Society, Volume 113, Issue 3, March 2026.
Abstract Collapsed ancient solutions to the homogeneous Ricci flow on compact manifolds occur only on the total space of principal torus bundles. Under an algebraic assumption that guarantees flowing through diagonal metrics and a tameness assumption on the collapsing directions, we prove that such solutions have additional symmetries, that is, they ...

Seismic Waves Do Sense Fracture Connectivity: Experimental Validation

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Fracture connectivity is a key parameter controlling fluid flow throughout the Earth's crust. While some theoretical and numerical studies suggest that seismic waves are sensitive to fracture connectivity, an experimental validation of this critically important phenomenon was so far unavailable.

Martian Atmospheric Loss Through Foreshock Transient Events

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract At Mars, the MAVEN spacecraft has made observations of Hot Flow Anomalies (HFAs) in the foreshock. Due to the bow shock's proximity to the planet, it is theorized that HFAs contribute to atmospheric escape at Mars through the excavation of ionospheric ions.

Detectability of Phytoplankton Biomass Extremes Using Simulated Satellite Chlorophyll Observations

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Extreme open‐ocean phytoplankton events can influence marine ecosystems, yet their global occurrence, drivers, and consequences remain poorly understood. Most large‐scale studies rely on satellite chlorophyll, which provides only a surface view, is affected by physiological variability, and is often missing due to clouds and low sunlight. Here,

N-Soliton Solutions to a New (2 + 1) Dimensional Integrable Equation

, 1998
We give explicitly N-soliton solutions of a new (2 + 1) dimensional equation, $ _{xt} + _{xxxz}/4 + _x _{xz} + _{xx} _z/2 + \partial_x^{-1} _{zzz}/4 = 0$. This equation is obtained by unifying two directional generalization of the KdV equation, composing the closed ring with the KP equation and Bogoyavlenskii-Schiff equation.

Two-dimensional stationary soliton gas

Physical Review Research
We study two-dimensional stationary soliton gas in the framework of the time-independent reduction of the Kadomtsev-Petviashvili (KPII) equation, which coincides with the integrable two-way “good” Boussinesq equation in the xy plane.
