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.
Using a global existence result due to A. Granas et al. [7] and the barrier strips technique, we study the solvability of the boundary value problem x′′′ = f (t, x, x′, x′′), x(0) = A, x′(0) = B, x′′(1) = C where f :[0,1]×ℝ3→ℝ is continuous. The obtained sufficient conditions guarantee the existence of at least one solution in C3 [0,1] which may be nonnegative, monotone and convex.
