VARIATIONS OF THE LOCAL ELECTRIC OF THE ATMOSPHERE UNDER THE INFLUENCE OF THUNDERSTORM EVENTS

Наука. Инновации. Технологии, 2022
Space weather and thunderstorms are among the insufficiently studied atmospheric processes that make a nonstationary contribution to the formation of the global electrical circuit.

Boundary‐Dependent Sleep–Wake Dysregulation in Idiopathic Hypersomnia

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Idiopathic hypersomnia (IH) presents with excessive daytime sleepiness (EDS) despite apparently preserved nocturnal sleep, challenging traditional models of hypersomnolence based on sleep loss or fragmentation. We aimed to test the hypothesis that EDS in IH reflects excessive stabilization of the sleep state, consistent with ...

On Einstein-non linear-Maxwell-Yukawa de-Sitter black hole thermodynamics

Nuclear Physics B, 2021
We investigate the thermodynamics of the Einstein-non linear-Maxwell-Yukawa black hole solution in de Sitter spacetime. After presenting the black hole solution and its horizons, we use different thermodynamical points of view to probe the phase ...

On the role of clouds in the fair weather part of the global electric circuit [PDF]

Atmospheric Chemistry and Physics, 2014
Clouds in the fair weather return path of the global electric circuit (GEC) reduce conductivity because of the limited mobility of charge due to attachment to cloud water droplets, effectively leading to a loss of ions. A high-resolution GEC model, which

The contribution of sprites to the global atmospheric electric circuit [PDF]

Earth, Planets and Space, 2006
Abstract The global static electric field in the global atmospheric electric circuit resulting from mesospheric sprite discharges is inferred from a coupled model for the global static and dynamic electric fields derived from Maxwell’s equations.

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

Advanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Empirical evidence for multidecadal scale global atmospheric electric circuit modulation by the El Niño-Southern Oscillation

Environmental Research Letters, 2022
The El Niño-Southern Oscillation (ENSO) modifies precipitation patterns across the planet. Charge separation in disturbed weather and thunderstorms drives the global atmospheric electric circuit (GEC), hence ENSO-induced precipitation changes are ...

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

Advanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

AC and DC global electric circuit properties and the height profile of atmospheric conductivity

Annals of Geophysics, 2016
An apparent discrepancy is pointed out - at all heights, and by up to an order of magnitude - between the height profiles of atmospheric conductivity derived at AC using ELF propagation studies, especially from information on Schumann resonance of the ...
