Global Ionospheric Responses to Four X‐Class Solar Flares in November 2025
Space Weather, Volume 24, Issue 11, November 2026.Abstract We investigate global ionospheric responses to four X‐class solar‐disk flares that occurred in November 2025 from the same solar active region, using multi‐instrument observations including GNSS, ionosonde, geomagnetic and GOES solar irradiance data. Pronounced dayside TEC enhancements are observed for three flares (#2 X1.2, #3 X5.1, and #4 X4.

Photons and temporality in quantum electrodynamics [PDF]
, 2008 The lowest order processes described within quantum electrodynamics are free from the problem with infinities in the theory, and can be dealt with disregarding the need for charge and mass renormalization.

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract Equatorial plasma bubbles (EPBs) are ionospheric irregularities generated by Rayleigh–Taylor instability (RTI) that disrupt satellite communications. We quantify secular change of RTI growth rates and isolate underlying drivers using WACCM‐X simulations.

The renormalization of charge and temporality in quantum electrodynamics [PDF]
, 2008 In this article it is intended a closer look at the renormalization procedure used in quantum electrodynamics to cope with the divergent integrals that appear in higher-order calculations within the theory.

Electrodynamic influence on the diurnal behaviour of neutral daytime airglow emissions [PDF]
Annales Geophysicae, 2016 The diurnal variations in daytime airglow emission intensity measurements at three wavelengths OI 777.4 nm, OI 630.0 nm, and OI 557.7 nm made from a low-latitude location, Hyderabad (17.5° N, 78.4° E; 8.9° N MLAT) in India have been investigated.

Is the relativity principle consistent with electrodynamics? Towards a logico-empiricist reconstruction of a physical theory [PDF]
, 2009 It is common in the literature on electrodynamics and relativity theory that the transformation rules for the basic electrodynamical quantities are derived from the hypothesis that the relativity principle (RP) applies for Maxwell's electrodynamics.

From Nano‐ to Picocavities: The Role of Atomistic Features
Small Structures, Volume 7, Issue 10, October 2026.Atomistic features strongly affect the plasmonic response of Ag and Au nano‐ and picocavities. By analyzing induced charge densities, electric field maps, and localization areas, the role of atomistic morphology in controlling field confinement and enhancement is revealed, establishing a direct structure–property relation between atomic‐scale features ...

The concept of vacuum in quantum electrodynamics [PDF]
, 2010 A re-evaluation of the concept of vacuum in quantum electrodynamics is presented, focusing on the vacuum of the quantized electromagnetic field. In contrast to the ‘nothingness’ associated to the idea of classical vacuum, subtle aspects are found in ...

Different lineages of Chikungunya virus in Equatorial Guinea in 2002 and 2006. [PDF]
, 2010 Chikungunya virus is a mosquito-borne virus that causes an acute febrile infection and severe arthralgia and is considered a re-emergent pathogen. During a study investigating arboviruses causing febrile infection in infants in Bata, Equatorial Guinea ...
