Lie group analysis, solitons, self-adjointness and conservation laws of the nonlinear elastic structural element equation

Journal of Taibah University for Science
This study is based on the Lie group method for the nonlinear elastic structural element equation (ESE Equation). We obtain a three-dimensional Lie algebra. By utilizing this Lie algebra a four-dimensional optimal system is constructed. The governing ESE

On the Generation of Pre‐Sunrise Equatorial Plasma Bubbles in Southeast Asia During the Geomagnetic Storm of May 2024

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract A set of fresh Equatorial Plasma Bubbles (EPBs) formed during pre‐sunrise hours in the Southeast Asian sector amid the recovery phase of May 2024 geomagnetic storm. They offered new insights into their formation mechanism. This study used Total Electron Content (TEC) and Rate of TEC Index maps over Indonesia, along with ionosondes in Thailand ...

ESA Swarm Satellites Plasma Density Products: Comparison and Validation Against Incoherent Scatter Radars Observations

Space Weather, Volume 24, Issue 8, August 2026.
Abstract The European Space Agency's Swarm mission has provided over a decade of continuous in situ measurements of the topside ionospheric plasma. With the release of various official plasma density products and the development of several calibration methods, selecting the most reliable data set has become an important issue for the scientific ...

Temperature evolution of the high‐harmonic magnetic modulations in DyFeO3

Journal of Applied Crystallography, Volume 59, Issue 4, Page 1332-1337, August 2026.
The temperature evolution of the high‐harmonic incommensurate magnetic ordering of Dy3+ in DyFeO3 orthoferrite is compared with the literature results on the soliton lattice of TbFeO3 observed in an external magnetic field.We report on the temperature evolution of magnetic satellites associated with the incommensurate magnetic ordering of Dy3+ ions in ...

Solitary Waves of Moderate Amplitude and Dispersive Radiation in the Serre Equations: The Extended KdV–Whitham Approximation

Studies in Applied Mathematics, Volume 157, Issue 2, August 2026.
ABSTRACT We consider the extended Korteweg–de Vries (eKdV) equation as a model for long moderately nonlinear surface water waves and use it to describe the evolution of initial conditions generating solitary waves with and without significant dispersive radiation, as well as cases of pure dispersive radiation without any solitary waves.

Estimating Surface Explosion Yield From Single‐Channel Infrasound Signals at Regional Distances With Random‐Forest Regression

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.

Tsunami Traveling Ionospheric Disturbances Triggered by the 29 July 2025 Mw 8.8 Kamchatka Earthquake Observed in Japan and Taiwan

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 ...

Unprecedented Extreme Dust Storm Triggered by Stratosphere‐Troposphere Interactions

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract An unprecedented dust storm struck southern China in April 2025, affecting hundreds of millions of people in regions rarely impacted by dust storms and challenging existing understanding of lower‐latitude dust storms. Here, we show that polar stratospheric signals enabled this event by modulating tropospheric teleconnection, revealing an ...
