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

In the paper we describe our approach for simulation of rarefied gas flows by pairs of quasiparticles. Real molecules are jumping in the velocity space due to collisions but quasiparticles pairs rotates slowly with angular velocity which depends on the distribution function. Dynamics of quasiparticles and real molecules are completely different but distribution functions coincide. The two-particle approach provides fulfillment of the particle, momentum, and energy conservation laws in numerical simulations automatically.
