Simulating Bouncing Packets Driven by Ducted Lightning‐Generated Whistlers: Comparison With SAMPEX Observations

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Bouncing packets are quasi‐periodic microbursts separated by the electron bounce period. Solar Anomalous and Magnetospheric Particle Explorer observations revealed relativistic (>1 MeV) inner‐belt bouncing packets with “crown,” “decaying,” and “flat” envelopes.

Nullwertige Nickelatome stabilisiert in oberflächengestützten metallorganischen Ketten

open access: yesAngewandte Chemie, Volume 138, Issue 39, 21 September 2026.
Mit 9,10‐Dicyanoanthracen koordinierte nullwertige Ni(0) d10‐Zentren auf Ag(100), die eine metallorganische Kette mit quasi‐eindimensionaler Metall‐Ligand‐Wechselwirkung bilden. ZUSAMMENFASSUNG Die Stabilisierung von nullwertigen Ni(0)‐Zentren in ausgedehnten Koordinationsnetzwerken bleibt aufgrund ihrer ausgeprägten Reaktivität und Anfälligkeit für ...

Neoclassical toroidal plasma viscosity in bounce-transit and drift resonance regimes in tokamaks

open access: yesNuclear Fusion, 2023
Neoclassical toroidal plasma viscosity in the bounce-transit and drift resonance regimes is calculated using a version of the drift kinetic equation that encompasses the physics of the nonlinear trapping and quasilinear plateau regimes in tokamaks. It is

On the asymptotically cubic generalized quasilinear Schrödinger equations with a Kirchhoff-type perturbation

open access: yesFrontiers in Physics, 2023
In this paper, we consider the non-existence and existence of solutions for a generalized quasilinear Schrödinger equation with a Kirchhoff-type perturbation.

The Benjamin–Ono Equation in the Zero‐Dispersion Limit for Rational Initial Data: Generation of Dispersive Shock Waves

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 9, Page 2107-2157, September 2026.
ABSTRACT The leading‐order asymptotic behavior of the solution of the Cauchy initial‐value problem for the Benjamin–Ono equation in L2(R)$L^2(\mathbb {R})$ is obtained explicitly for generic rational initial data u0$u_0$. An explicit asymptotic wave profile uZD(t,x;ε)$u^\mathrm{ZD}(t,x;\epsilon)$ is given, in terms of the branches of the multivalued ...

Investigation of Doubly Nonlinear Parabolic Equation

open access: yesProceedings of the International Conference on Applied Innovations in IT
We study the properties of solutions for a porous medium equation (PME) in non-divergent form with a source term. The PME is a fundamental model in various physical and biological processes, including fluid flow through porous media, heat transfer, and ...

Weak Turbulence and Quasilinear Diffusion for Relativistic Wave-Particle Interactions Via a Markov Approach

open access: yesFrontiers in Astronomy and Space Sciences, 2022
We derive weak turbulence and quasilinear models for relativistic charged particle dynamics in pitch-angle and energy space, due to interactions with electromagnetic waves propagating (anti-)parallel to a uniform background magnetic field.

Rothe Time Discretization and Weak Solutions for a Cutoff Westervelt System

open access: yesNumerical Methods for Partial Differential Equations, Volume 42, Issue 5, September 2026.
ABSTRACTWe study a fully implicit Rothe time discretization for a cutoff first‐order formulation of the Westervelt equation. The key ingredients are the enthalpy variable and the primitive mobility variable, which turn each nonlinear time step into a uniformly monotone elliptic problem and avoid higher‐order energy estimates and inverse inequalities ...

Electron‐Driven Instabilities in Jupiter's Magnetodisc

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Thermal electrons in Jupiter's magnetodisc have been observed to be anisotropic with higher parallel temperature compared to perpendicular. In this work, we used previously‐derived electron properties (Sarkango et al., 2025, https://doi.org/10.1029/2025gl118209) to calculate electron β‖ ${\beta }_{\Vert }$ and compared the observed anisotropy ...

Existence and comparison results for quasilinear evolution hemivariational inequalities

open access: yesElectronic Journal of Differential Equations, 2004
We generalize the sub-supersolution method known for weak solutions of single and multivalued nonlinear parabolic problems to quasilinear evolution hemivariational inequalities.
