Connection of Jonsson theory with some Jonsson polygons theories

Қарағанды университетінің хабаршысы. Математика сериясы, 2019
This article presents the result related to the model - theoretic properties of special subsets of the semantic model of some fixed Jonsson theory. The specialty of these sets is due to their definability and closure.

Criterion for the cosemanticness of the Abelian groups in the enriched signature

Қарағанды университетінің хабаршысы. Математика сериясы, 2018
In the present paper we give a criterion of the cosemanticness relative to the Jonsson spectrum of the model in the class of Abelian groups with a distinguished predicate.

The rotation of surviving companion stars after type Ia supernova explosions in the WD+MS scenario [PDF]

, 2013
In the SD scenario of SNe Ia the companion survives the SN explosion and thus should be visible near the center of the SN remnant and may show some unusual features.

The Mass of the Black Hole in Cygnus X-1 [PDF]

, 2011
Cygnus X-1 is a binary star system that is comprised of a black hole and a massive giant companion star in a tight orbit. Building on our accurate distance measurement reported in the preceding paper, we first determine the radius of the companion star ...

Properties of hybrids of Jonsson theories

Қарағанды университетінің хабаршысы. Математика сериясы, 2018
This work is an introduction to the study of the properties of a new concept, as a hybrid of Jonsson theories. We define the basic concepts and framework for studying the model-theoretic properties of these concepts.

The Impact of the Social Determinants of Human Health on Companion Animal Welfare

Animals, 2023
The social determinants of health (SDH) focus on the social, physical and economic factors that impact human health. Studies have revealed that animal guardians face a range of challenges in attaining positive welfare outcomes for their companion animals,

Four Years of Type Ia Supernovae Observed by TESS: Early-time Light-curve Shapes and Constraints on Companion Interaction Models

The Astrophysical Journal, 2023
We present 307 type Ia supernova (SN) light curves from the first 4 yr of the Transiting Exoplanet Survey Satellite mission. We use this sample to characterize the shapes of the early-time light curves, measure the rise times from first light to peak ...

Small models of hybrids for special subclasses of Jonsson theories

Қарағанды университетінің хабаршысы. Математика сериясы, 2019
This article presents the result related to the model - theoretic properties of special subsets of the semantic model of some fixed Jonsson theory. The specialty of these sets is due to their definability and closure.
