Abstract
In the present paper we consider the nonlocal boundary value perturbation problem { ε2∂2u(t,x)∂t2−(a(x)ux(t,x))x+δu(t,x)=f(t,x),0<t

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.
