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

For solving the problem of rate mode of multistage hot deformation optimization in order to reduce the impact of the stages number on the structure of a nonlinear programming problem, it is suggested to search the solution in the form of multistage rate change with the equal duration of stages and with rate change by the path, set by polynomial and exponential functions.
