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.
We consider the classical synchronised multiple access system with a single transmission channel and a randomised transmission protocol (ALOHA). It is well known that this algorithm is not stable, but under some conditions metastability effect is observed (i.e. the algorithm provides the required quality of service on finite but long-term time intervals). We study a method to estimate the metastability time interval for an input stream of i.i.d. sequence of random values.
