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 We construct a pair of mutually reducible linear differential systems with bounded continuous coefficients on the time half-line with the following property: there exists a countable set of real numbers such that, for each number in this set, the systems obtained by multiplying the coefficient matrices of the original systems by that number cannot be reduced to each other but are reducible to each other in the generalized sense.
