Normal Jonsson theories and their Kaiser classes

Қарағанды университетінің хабаршысы. Математика сериясы
We present results concerning new notion connected with the study of Jonsson theories. The new notion is a Kaiser class of models for arbitrary Jonsson theories.

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.

Fundamental bounds on transmission through periodically perforated metal screens with experimental validation

, 2019
This paper presents a study of transmission through arrays of periodic sub-wavelength apertures. Fundamental limitations for this phenomenon are formulated as a sum rule, relating the transmission coefficient over a bandwidth to the static polarizability.

Tropically convex constraint satisfaction

, 2017
A semilinear relation S is max-closed if it is preserved by taking the componentwise maximum. The constraint satisfaction problem for max-closed semilinear constraints is at least as hard as determining the winner in Mean Payoff Games, a notorious ...

Dynamics of the 2D two-component plasma near the Kosterlitz-Thouless transition

, 1999
We study the dynamics of a classical, two-component plasma in two dimensions, in the vicinity of the Kosterlitz-Thouless (KT) transition where the system passes from a dielectric low-temperature phase (consisting of bound pairs) to a conducting phase. We

Failure in Motion: A Framework for Capability Erosion and Institutional Dysfunction

Strategic Change, EarlyView.
ABSTRACT Drawing on the literature on capability erosion and institutional dysfunction (ID), this study develops a conceptual framework that sheds new light on how the interaction between capability erosion and ID creates conditions for business failure across borders. By articulating two dimensions of heterogeneous capability and resource erosion (i.e.

Double factorization of the Jonsson spectrum

Қарағанды университетінің хабаршысы. Математика сериясы
First of all, we have to note that in this article, we introduced the new concepts of relations between Jonsson theories in the class of cosemanticness for some considered Jonsson spectrum.

Stored energies in electric and magnetic current densities for small antennas [PDF]

, 2013
Electric and magnetic currents are essential to describe electromagnetic stored energy, as well as the associated quantities of antenna Q and the partial directivity to antenna Q-ratio, D/Q, for general structures. The upper bound of previous D/Q-results

The Meritorious ‘Other’: The Interconnection of Merit and Race in EU Migration and Asylum Law

JCMS: Journal of Common Market Studies, EarlyView.
Abstract Adopting a law‐in‐context approach, this article suggests that merit‐based migrant selection in the European Union (EU) is implicitly shaped by racial dynamics. With a focus on EU law and more specifically on cases from the Netherlands and Germany, it argues that the growing emphasis on merit enables a limited number of ‘racialised others’ to ...
