Connection of Jonsson theory with some Jonsson polygons theories

open access: yesҚарағанды 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

open access: yesҚарағанды 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.

Properties of hybrids of Jonsson theories

open access: yesҚарағанды 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

open access: yesAnimals, 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,

Central types of convex fragments of the perfect Jonsson theory

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2019
In this paper, the central types of convex fragments of the perfect Jonsson theory are considered. The main goal of this paper is to redefine the A.D.

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

open access: yesThe 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

open access: yesҚарағанды 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.

Optical and Infrared Light Curves of the Eclipsing X-ray Binary V395 Car = 2S 0921-630 [PDF]

open access: yes, 2012
We present results of optical and infrared photometric monitoring of the eclipsing low-mass X-ray binary V395 Car (2S 0921-630). Our observations reveal a clear, repeating orbital modulation with an amplitude of about one magnitude in B, and V and a ...

Phenomenology of the companion-axion model: photon couplings

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
We study the phenomenology of the ‘companion-axion model’ consisting of two coupled QCD axions. The second axion is required to rescue the Peccei–Quinn solution to the strong-CP problem from the effects of colored gravitational instantons. We investigate
