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 The configurations containing one or two hydrogen atoms in a A‐center are calculated by the MNDO and Xα‐DV methods. It is established that the hydrogen atom is bound with the oxygen of the A‐center forming a new paramagnetic center. The electrical activity of the A‐center is decreased by hydrogen passivation of the two silicon dangling bonds. However, the defect states are not removed from the band gap.
