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

An equation of the cascade process (Boltzmann type) for electrons is obtained and solved during the formation of primary knocked on atoms (PKA), taking into account energy losses in an elementary event. It is shown that the cascade probability function (CPF) is included in the solution of this equation. Using this solution, expressions for the PKA energy spectrum and defect concentration are obtained. A comparison of the calculations based on the concentration of Frenkel pairs with the experiment on the fixing points of dislocations shows their satisfactory agreement.
