Atmospheric Tides Imprint a Wavenumber‐4 Structure in Topside Ionospheric ELF Wave Intensity
Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Atmospheric tides produce a well known pronounced longitudinal wavenumber‐4 (WN‐4) structure in the ionosphere, but their influence on electromagnetic‐wave propagation through the ionosphere remains poorly constrained. Here we use DEMETER satellite measurements to show that the extremely low frequency (ELF) electric field in the low‐latitude ...

On tau functions associated with linear systems [PDF]
, 2012 \noindent {\bf Abstract} This paper considers the Fredholm determinant $\det (I-\Gamma_x)$ of a Hankel integral operator on $L^2(0, \infty )$ with kernel $\phi (s+t+2x)$, where $\phi$ is a matrix scattering function.

Motion of strings, embedding problem and soliton equations [PDF]
, 1981 The motion of a flexible string of constant length in E 3 in interaction, corresponding to a variety of physical situations, is considered. It is pointed out that such a system could be studied in terms of the embedding problem in differential geometry ...

The simplified Hirota’s method for studying three extended higher-order KdV-type equations
Journal of Ocean Engineering and Science, 2016 In this work we study three extended higher-order KdV-type equations. The Lax-type equation, the Sawada–Kotera-type equation and the CDG-type equation are derived from the extended KdV equation.

Bright solitary waves and non-equilibrium dynamics in atomic Bose-Einstein condensates [PDF]
, 2012 In this thesis we investigate the static properties and non-equilibrium dynamics of bright solitary waves in atomic Bose-Einstein condensates in the zero-temperature limit, and we investigate the non-equilibrium dynamics of a driven atomic Bose-Einstein ...

Global Occurrence of Solitary Waves in the Martian Magnetosphere
Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract This letter presents a global occurrence of bipolar solitary waves (SWs) in the Martian magnetosphere. We utilized medium‐frequency electric field measurements from October 2014 to December 2023 from the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft.

The action-angle transformation for soliton equations [PDF]
, 1990 For third order completely integrable equations in 1 + 1 dimensions canonical transformations which map (in the multi-soliton case) gradients of action variables to gradients of angle variables are constructed. Furthermore, this action-angle map is shown
