Existence and Multiplicity of Solutions for a Bi-Non-Local Problem

Mathematics, 2022
The aim of this paper is to investigate the existence and multiplicity of solutions for a bi-non-local problem. Precisely, we show that the above problem admits at least a non-trivial positive energy solution by using the mountain pass theorem ...

Predictions of Equatorial Vertical Plasma Drift Using TEC Data and a Neural Network Model

Earth and Space Science, Volume 12, Issue 6, June 2025.
Abstract Vertical plasma drift, vz, plays a key role in the dynamics, morphology, and space weather effects of the equatorial and low latitude ionosphere. Modeling the drift has been an on‐going effort for climatology‐based prediction. To address daily prediction, the Vertical drIfts: Predicting Equatorial ionospheRic dynamics (VIPER) model has been ...
