Air breakdown characteristics in plane-plane and sphere gap electrode configuration under lightning impulse [PDF]

open access: yes, 2014
This report describes the air breakdown characteristics in plane-plane and sphere gap electrode configuration under lightning impulse. The breakdown in air (spark breakdown) is the transition of a non-sustaining discharge into a self sustaining ...

Revisiting Mission‐Oriented Cancer Research to tackle the increasing burden of cancer in Europe–a policy perspective

open access: yesMolecular Oncology, EarlyView.
Translational cancer research and its implementation through competitively selected Comprehensive Cancer Centers across Europe should be the primary policy focus for addressing the increasing cancer burden in Europe and counteract the present main strategy to convert cancer to a chronic disease.

Characteristics of Impulse Discharges in Wet Soil

open access: yesThe Transactions of The Korean Institute of Electrical Engineers, 2017
This paper presents the experimental results related to soil ionization and electrical breakdown in a concentric hemispherical electrode system under lightning impulse voltages. Dynamic voltage-current and impedance-time characteristics of soil ionization were measured and analyzed. Also the electrical breakdowns of the soil gap were investigated.

Low-frequency phase diagram of irradiated graphene and periodically driven spin-1/2 $XY$ chain

open access: yes, 2017
We study the Floquet phase diagram of two-dimensional Dirac materials such as graphene and the one-dimensional (1D) spin-1/2 $XY$ model in a transverse field in the presence of periodic time-varying terms in their Hamiltonians in the low drive frequency (

Smoothing of Impulse Noise by Orthogonal Transform [PDF]

open access: yes, 1981
Electromagnetic impulse noise which is harmful to signal measurement or transmission of information, is smoothed by the orthogonal transform processor. The idealized impulse noise with infinitesimal duration and Gaussianly-distributed amplitude shows the
