Appearance of a Minimal Length in e+e- Annihilation

Advances in High Energy Physics, 2014
Experimental data reveal with a 5σ significance the existence of a characteristic minimal length le=1.57×10-17 cm at the scale E=1.253 TeV in the annihilation reaction e+e-→γγ(γ).

Persistence of the Prereversal Enhancement of the Equatorial Vertical Plasma Drifts Observed by ICON

Geophysical Research Letters
An important feature of equatorial ionospheric electrodynamics is the evening prereversal enhancement (PRE) of the eastward electric fields and the associated vertical plasma drifts. The magnitude, timing, and duration of the PRE are closely connected to

Electrodynamics of the Low-latitude Thermosphere by Comparison of Zonal Neutral Winds and Equatorial Plasma Bubble Velocity

, 2015
The coincident observations of nighttime thermospheric zonal neutral winds and equatorial plasma bubble (EPB) drift velocities over Brazil during the October–December,2009 and 2010 are used to examine the coupling relationship between the thermosphere ...

Impacts of Neutral Wind‐Driven Currents on Geomagnetic Disturbances and Magnetospheric Dynamics During the May 2024 Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract The neutral wind dynamo generates ionospheric currents that can significantly affect high‐latitude electrodynamics during geomagnetic storms, yet its role in global magnetosphere‐ionosphere coupling is often underrepresented. We quantify the impact of wind‐driven currents on geomagnetic disturbances (GMDs) and magnetospheric dynamics during ...

Michigan Geospace Model With Ensemble Forecasting and Particle Filtering: Modeling the May 2024 Extreme Storm

Space Weather, Volume 24, Issue 9, September 2026.
Abstract This paper introduces an updated version of the University of Michigan Geospace model. The Geospace model has been used for operational forecasting at the Space Weather Modeling Center of the National Oceanic and Atmospheric Agency since 2016 with regular updates. The current operational version, Geospace V2, was launched in 2021 and is driven

Development and Validation of the Whole Atmosphere Community Climate Model With Thermosphere and Ionosphere Extension (WACCM‐X 2.0)

Journal of Advances in Modeling Earth Systems, 2018
Key developments have been made to the NCAR Whole Atmosphere Community Climate Model with thermosphere and ionosphere extension (WACCM‐X). Among them, the most important are the self‐consistent solution of global electrodynamics, and transport of O+ in ...

Comparison between Weber's electrodynamics and classical electrodynamics [PDF]

, 2015
We present the main aspects of Weber's electrodynamics and of Maxwell's equations. We discuss Maxwell's point of view related to Weber's electrodynamics. We compare Weber's force with Lorentz's force.
