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 A nonlocal problem for an impulsive system of hyperbolic equations of second order with discrete memory is considered. For solving this problem is applied Dzhumabaev’s parametrization method. Conditions for the existence and uniqueness of the nonlocal problem for an impulsive system of hyperbolic equations with discrete memory are established. An algorithm for finding approximate solution this problem is offered.
