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

It is well known that the application of the weight redundancy in self-calibrating DAC enables to lower considerably, the requirements regarding the accuracy of digits weight formation, particularly in multidigit code-current converters and the idea of laser adjustment of the resistor matrices nominals. It is also known, that the construction of ADC of the bit-wise balancing on the base of such DAC additionally enables to increase (by an order or more) the operation speed as a result of a considerable reduction of the balancing cycle duration.
