Ellerman bombs and UV bursts: transient events in chromospheric current sheets

, 2019
Ellerman bombs (EBs) and UV bursts are both brightenings related to flux emergence regions and specifically to magnetic flux of opposite polarity that meet in the photosphere.

A Simplified Model of Coaxial, Multilayer High-Temperature Superconducting Power Cables with Cu Formers for Transient Studies

Energies, 2019
Bypassing transient current through copper (Cu) stabilizer layers reduces heat generation and temperature rise of high-temperature superconducting (HTS) conductors, which could protect HTS cables from burning out during transient conditions. The Cu layer

Ultrahigh Hot Carrier Transient Photocurrent in Nanocrystal Arrays by Auger Recombination. [PDF]

, 2019
In this report, we show that a new mechanism for carrier transport in solution-processed colloidal semiconductor nanocrystal arrays exists at high excitation intensity on ultrafast time scales and allows for facile intrinsic transport between as-prepared

Ultrahigh-Energy Photons as a Probe of Nearby Transient Ultrahigh-Energy Cosmic-Ray Sources and Possible Lorentz-Invariance Violation

, 2009
Detecting neutrinos and photons is crucial to identifying the sources of ultrahigh-energy cosmic rays (UHECRs), especially for transient sources. We focus on ultrahigh-energy gamma-ray emission from transient sources such as gamma-ray bursts, since >EeV ...

Transient analysis of proton electrolyte membrane fuel cells (PEMFC) at start-up and failure [PDF]

, 2007
A two-dimensional, transient, single-phase computational model, incorporating water transport in the membrane and the flow and transport of species in porous gas diffusion electrodes is developed to evaluate the transient performance of a PEMFC with ...

Current limiting algorithms and transient stability analysis of grid-forming VSCs

, 2020
This paper consists first in comparing the well-known virtual impedance and current saturation algorithms in case of a three-phase short circuit. During the fault, the virtual impedance has an indirect action on the AC current since it depends mainly on ...
