Mesospheric and Lower Thermospheric Responses to the May 2024 Geomagnetic Storm in the Antarctic Peninsula

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract We analyze the response of mean winds and semidiurnal tides (SDTs) in the mesosphere and lower thermosphere (MLT; ∼70–110 km altitude) to the May 2024 geomagnetic super storm, based on meteor radar (MR) observations from King Sejong Station (KSS; geographic: 62.22°S, 58.78°W; geomagnetic: 53.27°S, 10.88°E) in the Antarctic Peninsula.

Exploring the Jacobi elliptic and soliton solutions for the nonlinear (1+1)-dimensional Shynaray-IIA equation with conformable derivative

Results in Optics
In this paper, we study the application of the Jacobi elliptic function expansion method for finding the new exact solutions to the nonlinear (1+1)- dimensional Shynaray-IIA equation, including the conformable derivative.

Influence of Acrylonitrile Content on Processing, Morphology, Thermal Behavior, and Mechanical Properties of PA/NBR Thermoplastic Vulcanizates

Journal of Applied Polymer Science, Volume 143, Issue 11, March 15, 2026.
Influence of acrylonitrile (ACN) content on the processing behavior and morphological development of PA/NBR thermoplastic vulcanizates. Torque‐time profiles, SEM, and SEM/AFM images show that an intermediate ACN level (38%) promotes improved phase dispersion and morphological uniformity, especially with increased processing time, resulting in the most ...

Theory of multivariable Bessel functions and elliptic modular functions

Le Matematiche, 1998
The theory of multivariable Bessel functions is exploited to establish further links with the elliptic functions. The starting point of the present investigations is the Fourier expansion of the theta functions, which is used to derive an analogous ...

Methods Based on Polynomial Chaos for Quadratic Delay Differential Equations With Random Parameters

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT We consider systems of delay differential equations (DDEs), including a single delay and a quadratic right‐hand side. In a system, parameters are replaced by random variables to perform an uncertainty quantification. Thus the solution of the DDEs becomes a random process, which can be represented by a series of the generalised polynomial chaos.
