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.
The behaviour of water droplets condensed on ferromagnetic particles of submicron sizes, which are falling in a gaseous medium, is investigated. Under intensive lighting a number of droplets move in a magnetic field similarly to objects having magnetic charge. The mean value of this charge coincides with the value of the Dirac monopole charge.
