On the puzzling feature of the silence of precursory electromagnetic emissions [PDF]
, 2013 It has been suggested that fracture-induced MHz-kHz electromagnetic (EM) emissions, which emerge from a few days up to a few hours before the main seismic shock occurrence permit a real-time monitoring of the damage process during the last stages of ...

Frequency-dependent streaming potentials: a review [PDF]
, 2012 The interpretation of seismoelectric observations involves the dynamic electrokinetic coupling, which is related to the streaming potential coefficient. We describe the different models of the frequency-dependent streaming potential, mainly the Packard's

A Hybrid Deep Learning‐Based Forecasting Model for the Peak Height of Ionospheric F2 Layer
Space Weather, Volume 21, Issue 10, October 2023., 2023 Abstract To achieve accurate forecasting of the peak height of the ionospheric F2 layer (hmF2), we propose a hybrid deep learning model of improved seagull optimization algorithm (ISOA) optimized long short‐term memory (LSTM) model based on a complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN) theory.
