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

This paper addresses the solvability of two-point boundary value problems for linear differential-algebraic equations with time-varying coefficients. The proposed method employs the standard canonical form to decouple the system into an ordinary differential part and an algebraic part. By introducing an appropriate parameter, we transform the original problem into the solvability of an associated linear algebraic system. This reduction leads to a constructive solvability criterion for the boundary value problem. A comprehensive example is provided to demonstrate the applicability and effectiveness of the proposed approach.
