The paper presents a study of the electromagnetic field created by a flat circular
aperture in the near zone. The analytical method, based on the search for the antiderivative of
the pulse-transient characteristic, adequately estimates the strength of the electromagnetic field
of the aperture antenna. For proof, a comparison of the analytical method of calculation with the
well-known numerical method FIT is given. The advantage of the analytical method from the
point of view of computational resources is shown.

Semiconductor lead halide perovskites have attracted significant attention for various applications. Understanding the impact of material composition on optical properties is essential for optimizing device performance. Here, we performed magneto-optical spectroscopy on high-quality bulk CsPbBr3, MAPbBr3, and MAPbI3 single crystals under magnetic fields of up to 30 T. The results revealed distinctive excitonic responses to the magnetic ...

Affective political polarization is comprehensively considered in combination of its emotional, behavioral and cognitive aspects. They manifest themselves in the differences between an individual's attitude towards politically like-minded people (the in-group) and opponents (the out-group), includingemotions experienced, willingness to cooperate, and a tendency to attribute positive or negativequalities.
Particular attention is paid to the problem of differences between the intensity of manifestations of affective political polarization in the online environment compared to traditional forms of communication. Most contemporary researchers predict a higher level of polarization ...

Polarization measurements were carried out in a standard three-electrode electrochemical cell at room temperature using a platinum counter electrode and a saturated silver chloride reference electrode. For Al0.5CoCrFeNiCu0.5 and Al0.5CoCrFeNiCu0.5Ag0.1, ...

Let U be the unitriangular group over a finite field. We consider an interesting class of irreducible complex characters of U, so-called characters of depth 2. This is a next natural step after characters of maximal and submaximal dimension, whose description is already known. We explicitly describe the support of a character of depth 2 by a system ...

A measurement of the transverse polarization of the Λ and Λ¯ hyperons in pNe fixed-target collisions at sNN = 68.4 GeV is presented using data collected by the LHCb detector. The polarization is studied using the decay Λ → pπ− together with its charge conjugated process, the integrated values measured are

This article examines two opposing media consumption trends—news avoidance and doomscrolling—through the lens of media environment and societal fragmentation. News avoidance refers to the conscious limitation of economic or socio-political content consumption to maintain emotional well-being, while doomscrolling is defined as compulsive and excessive attention to negative news. The study is based on 91 semi-structured ...

Among the many philosophical directions, analytical philosophy is considered as one of the least practical. However, from time to time, the analytical method is also used in those areas of philosophy that are obviously focused on applying the results of theoretical research to social practice. The question arises: how analytical philosophical constructs fit into a ...

In two-dimensional (2D) materials, breaking the inversion symmetry plays an important role in valleytronics. Ferrovalley (FV) materials can achieve spontaneous valley polarization (VP) without additional modulation due to the magnetic exchange interaction and strong spin–orbit coupling. Using first-principles calculations, we predict a new 2D material, Janus FeClSH, which exhibits a large spontaneous VP. This monolayer ...
