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 Now exist several alternative cosmological models that describe observable properties of our universe. In particular, it is such models as F (R) and F (T ) gravity. We consider properties of their generalization as F (R, T ) model of gravity with kessence. We obtained some exact solutions of particular cass of scale factor a for general formof the F (R, T ) functions with scalar field. These solutions describe the accelerated/deccelerated periods of the universe.
