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 In this paper we study a singular parabolic operator$$Lu=\frac{\partial u}{\partial t}-\frac{\partial^2 u}{\partial x^2}+q(x)u$$initially defined on $C^{\infty}_{0,\pi}(\bar{\Omega})$, where $\bar{\Omega}=\{(t,x):-\pi\leq t\leq \pi, -\infty0$ is a constant. {\bf Example.} $q(x)=e^{1000|x|}, -\infty
