Development of Antenna Module for the Intelligent RFID System
P. 1–4.
This work is aimed at studying the possibility of using antennas of different polarization, in particular linear and circular, to develop an antenna unit that will be used in RFID systems that perform identification and determine the location of objects marked with tags in space. Research and development of the antenna module will allow you to identify objects in space using a smaller number of antennas compared to the number of zones in which marked objects are located.

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 ...

The electrochemical behavior of the as-cast Al0.5CoCrFeNiCuxAgy (x = 0.25, 0.5; y = 0, 0.1) high-entropy alloys (HEAs) in a 0.5M H2SO4 solution was studied. 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 ...

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 ...

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 ...

Value polarization is one of the key factors in societal development. This research focuses on whether opinions concerning gender roles in the domestic and public spheres are polarized in European societies, a topic still under-investigated. Based on the fifth wave of European Values Study data (2017–2020), the study shows that gender role attitudes in the ...

The phase- and energy-resolved polarization measurements of accreting X-ray pulsars (XRPs) allow us to test different theoretical models of their emission, and they also provide an avenue to determine the emission region geometry. We present the results of the observations of the XRP GX 301−2 performed with the Imaging X-ray Polarimetry Explorer (IXPE). A persistent ...
