ED‐Autoformer: A New Model for Precise Global TEC Forecast

Space Weather, Volume 23, Issue 6, June 2025.
Abstract Total electron content (TEC) is a key parameter for characterizing ionospheric morphology and significantly impacts the Global Navigation Satellite System. The ionosphere responds dramatically to solar and geomagnetic activity, leading to substantial TEC fluctuations and disturbances.

Cosmic Rays and the Askaryan Effect Reveal Subsurface Structure and Buried Ice on the Moon

Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.
Abstract We present the first full‐wavelength numerical simulations of the electric field generated by cosmic ray impacts into the Moon. Billions of cosmic rays fall onto the Moon every year. Ultra‐high energy cosmic ray impacts produce secondary particle cascades within the regolith and subsequent coherent, wide‐bandwidth, linearly‐polarized radio ...

A Critical Distance Parameter for Random Vibration Fatigue Life Estimation of Notched Metallic Structures in the Frequency Domain

International Journal of Mechanical System Dynamics, Volume 5, Issue 1, Page 101-112, March 2025.
ABSTRACT A critical distance parameter is introduced to describe the stress gradient effect of notched metallic structures under random vibration loadings, which is the frequency domain expression of the theory of critical distance (TCD) based line method stress.

Signature of matter–field coupling in quantum–mechanical statistics

Frontiers in Quantum Science and Technology
The connection between the intrinsic angular momentum (spin) of particles and quantum statistics is established by considering the response of identical particles to a common background radiation field.

Universe inflation and nonlinear electrodynamics

European Physical Journal C: Particles and Fields
We analyse the inflation of the universe when the source of gravity is electromagnetic fields obeying nonlinear electrodynamics, with two parameters and without singularities.

Chern-Simons induced thermal friction on axion domain walls

Journal of High Energy Physics
We study the dynamics and interactions of the solitonic domain walls that occur in realistic axion electrodynamics models including the Chern-Simons interaction, aϵ μνλσ F μν F λσ , between an axion a(x) of mass m a , and a massless U(1) gauge field, e.g.
