Seismic Constraints of the 23 November 2025 Hayli Gubbi Eruption Sequence in Afar, Ethiopia
Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract On 23 November 2025, the Hayli Gubbi volcano in Afar (Ethiopia) erupted in a massive explosion. We present the first seismic characterization using data from 13 regional seismological stations. Seismograms reveal signals consisting of a minute‐long precursor, a main eruptive phase, and secondary events hours later.

On Soliton Equations of Exceptional Type
Journal of Algebra, 1994 The explicit structure of soliton equations in bilinear form is studied. The equations studied are those corresponding to A-D-E-type Kac-Moody algebra in the basic representation \(L(\Lambda_ 0)\), with principal or homogeneous realization. Using results of Kac-Wakimoto, describing these equations with a generalized Casimir operator, the author is able

Self‐Similar Blowup for the Cubic Schrödinger Equation
Communications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1831-1918, August 2026.ABSTRACT We give a rigorous proof for the existence of a finite‐energy, self‐similar solution to the focusing cubic Schrödinger equation in three spatial dimensions. The proof is computer‐assisted and relies on a fixed point argument that shows the existence of a solution in the vicinity of a numerically constructed approximation.

A Wrong Ansatz for Nonlinear Waves in the Stochastic Maccari System
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 8, August 2026.ABSTRACT This note is a short version of arXiv preprint arXiv:2508.12786 (2025), explicitly tailored to explain why the solutions of a stochastic Maccari system as found in ZAMM‐Journal of Applied Mathematics and Mechanics/Zeitschrift für Angewandte Mathematik und Mechanik 103, no. 5 (2023): e202100199. are wrong.

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.Abstract When detonated on the Earth's surface, large explosions emit distinctive acoustic signatures that propagate over vast distances with relatively low attenuation in the form of infrasound. Infrasound stations hundreds of kilometers from the impulsive source can record the propagated pressure signal, atmospheric conditions permitting.

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract The 29 July 2025 Mw 8.8 Kamchatka earthquake generated notable seismic and tsunami waves. The total electron content (TEC) derived by more than 1,400 ground‐based global navigation satellite system (GNSS) receiving stations in Japan and Taiwan is employed to examine the spatiotemporal evolution of seismic‐ and tsunami‐traveling ionospheric ...

A (2 + 1)-Dimensional Integrable Breaking Soliton Equation and Its Algebro-Geometric Solutions
MathematicsA new (2 + 1)-dimensional breaking soliton equation with the help of the nonisospectral Lax pair is presented. It is shown that the compatible solutions of the first two nontrivial equations in the (1 + 1)-dimensional Kaup–Newell soliton hierarchy ...

Vortex Light Bullets Guided by Disclination Defects
Nanophotonics, Volume 15, Issue 14, 27 July 2026.A new class of stable and thresholdless light bullets carrying vorticity, guided by the disclination defects introduced into Su–Schrieffer–Heeger‐like lattices with a focusing cubic nonlinearity, is reported. Different discrete rotational symmetry of the aperiodic lattice determines the allowed values of the topological charge of the vortex bullets ...

Third Harmonic Generation in Transparent Longitudinal Epsilon‐Near‐Zero Multilayers
Nanophotonics, Volume 15, Issue 14, 27 July 2026.Transparent longitudinal epsilon‐near‐zero stacks enable field‐enhanced nonlinear light generation while preserving high near‐infrared pump transmission. Broadband third‐harmonic generation is experimentally observed demonstrating that TLENZ architectures can mitigate pump‐loss limitations and offer a promising platform for transparent nonlinear ...
