Central types of convex fragments of the perfect Jonsson theory

BULLETIN OF THE KARAGANDA UNIVERSITY-MATHEMATICS, 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. Taimanov’s question for complete theories in the sphere of Jonsson fragments of formula -definable subsets of a Jonsson fixed theory’s semantic model.

Conditional Versus Unconditional Covariate Effects in Pharmacometric Models: Implications for Interpretation, Communication, and Reporting. [PDF]

CPT Pharmacometrics Syst Pharmacol
ABSTRACT This work investigates how correlations between covariates influence the estimation of their effects in pharmacometric models. The focus is on quantifying the impact on conditional and unconditional covariate effect estimates and assessing the consequences for model interpretation, communication, and dosing recommendations.

Adaptive Pruning for Increased Robustness and Reduced Computational Overhead in Gaussian Process Accelerated Saddle Point Searches. [PDF]

Chemphyschem
Optimal Transport: A permutation‐invariant "harness" measures true geometric distance improves performance and robustness. Gaussian process (GP) regression provides a strategy for accelerating saddle point searches on high‐dimensional energy surfaces by reducing the number of times the energy and its derivatives with respect to atomic coordinates need ...

Cooling Out or Branching Out? Accounting for the Aspirations-Attainment Paradox Among Immigrant Youth in Sweden. [PDF]

Br J Sociol
ABSTRACT In Sweden, as in many countries, immigrant youth tend to exhibit higher educational aspirations than native‐born youth, yet their attainment often falls short of their greater ambitions. This study, resulting from a research project focused on educational transitions in two Swedish municipalities, explores two mechanisms that help explain the ...

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.

Existentially prime Jonsson quasivarieties and their Jonsson spectra

Қарағанды университетінің хабаршысы. Математика сериясы, 2022
This article is devoted to the study of Jonsson quasivarieties in a signature enriched with new predicate and constant symbols. New concepts of semantic Jonsson quasivariety and fragment-conservativeness of the center of the Jonsson theory are ...
