Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

A model of solitary current filaments formation in a high pressure electronegative gas discharge is proposed. An explicit analytical solution of the balance equation for electrons including stepwise ionization, electron attachment and diffusional losses is obtained. The contracted distribution of electrons in the positive column is found to have a soliton form. The conditions favouring non-thermal plasma contraction are considered. Analytical results are compared successfully with simulation and experimental data.
