Parameters of the electric strength of air in a surface antenna during the emission of an ultrahigh-frequency pulse with a trapezoidal envelope

open access: yesФизика волновых процессов и радиотехнические системы, 2020
On the basis of the breakdown criterion and the equation of continuity of electrons in air, the amplitude and energy parameters of the electric strength of air in the surface antenna of a powerful microwave relativistic generator are determined when ...

Confinement effects from interacting chromo-magnetic and axion fields

open access: yes, 2005
We study a non-Abelian gauge theory with a pseudo scalar coupling \phi \epsilon ^{\mu \nu \alpha \beta} F_{\mu \nu}^a F_{\alpha \beta}^a in the case where a constant chromo-electric, or chromo-magnetic, strength expectation value is present.

Estimation of individually induced e-field strength during transcranial electric stimulation using the head circumference

open access: yesBrain Stimulation, 2021
Background: Head and brain anatomy have been related to e-field strength induced by transcranial electrical stimulation (tES). Individualization based on anatomic factors require high-quality structural magnetic resonance images, which are not always ...

Electric Dipole Moments and Polarizability in the Quark-Diquark Model of the Neutron

open access: yes, 2010
For a bound state internal wave function respecting parity symmetry, it can be rigorously argued that the mean electric dipole moment must be strictly zero.

The Variable Strength of Electrical Synapses [PDF]

open access: yesNeuron, 2016
In contrast to chemical synapses, less is known regarding the determinants of the strength of electrical synapses. New evidence from Szoboszlay et al. (2016) shows that the number of gap junctions is the dominant factor underlying the strength of electrical coupling between cerebellar interneurons.
