Data confidence 70 medium

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

Abstract The dynamic structure factor of dense two‐component plasmas is studied within the method of moments. A new model for the Nevanlinna parameter function is suggested. Our results on the dynamic structure factor satisfy the sum rules and other exact relations automatically, independently of the choice of a mathematically consistent model of the latter. A quantitative agreement is obtained with the molecular dynamics simulation data. Our approach permits to correct and complement the results of alternative approaches.
