Реферат
В статье рассмотрена новая методика экспериментального атеросклероза на крысах линии Wistar, которая берет в своем начале полиэтиологическую теорию развития заболевания. Был проведен эксперимент и полученные результаты оценивали степень взаимодействия факторов нагрузки, которые заключались в одновременной постановке экспериментального гипотиреоза при помощи Мерказолила, иммуносупрессии Метилпреднизолоном на фоне гепатотоксического действия раствора этилового спирта и классической атерогенной диеты. В работе приведены предварительные данные за две недели, которые достигли границы верхней нормы у одной из групп, а так же значительное достоверное повышение уровня ЛПоНП выше нормы.
Ключевые слова: экспериментальный атеросклероз, патогенез заболевания, сердечно-сосудистая патология.

Summary
The article describes a new method of experimental atherosclerosis in rats of Wistar line, which originates in the theory that disease has a multifactorial ethiology. Experiment and the results can show the interaction of atherogenic factors, which consisted in the simultaneous staging of experimental hypothyroidism using Mercazolilum, methylprednisolone immunosuppression on the background of hepatotoxic action of ethyl alcohol solution and atherogenic diet. This work shows the preliminary data for two weeks, in which the upper border of biochemical rate was reached in one of the groups, as well as a significant increase in the level of VLDL above normal.
Keywords: experimental atherosclerosis, the pathogenesis of the disease, cardiovascular disease
Improved PSP and U-Net architectures for forest segmentation in remote sensing pictures
No full textSlyusar V., Sliusar I., Pavlenko A. Improved PSP and U-Net architectures for forest segmentation in remote sensing pictures.// IEEE 2nd Ukrainian Microwave Week (Virtual Event) IEEE UkrMW-2022, 14 – 18 November, 2022. - V. N. Karazin Kharkiv National University, Kharkiv, Ukraine. – 4 p. DOI: 10.1109/UkrMW58013.2022.10037105.Various PSP and U-Net architectures for forest segmentation in remote sensing pictures have been proposed and investigated. The main improvements of the proposed architectures are based on using the BathNormalization layers, replacing MaxPool2D layers with AveragePooling2D, changing Conv2DTranspose to UpSampling2D blocks, etc. For the training of neural networks was used modified dataset of 128x128 pictures based on the dataset from Kaggle. As a result of improving architecture was given the maximum segmentation accuracy of 80.8 % on the validation set of pictures

Study of a Metamaterial Unit Cell with a Flat Möbius Strip: Frequency Characteristics and DNG Bands. 2025 IEEE 30th International Seminar/Workshop on Direct and Inverse Problems of Electromagnetic and Acoustic Wave Theory (DIPED). Tbilisi, Georgia, 8–10 September 2025. P. 259–263. ISBN 979-8-3315-8814-4. DOI: 10.1109/DIPED66951.2025.11194616.This work reports the results obtained for a novel metamaterial unit cell architecture developed using the concept of a flat Möbius strip. The modeling was performed using the Ansys HFSS software package. The influence of various structural modifications and substrate materials on the frequency bands with simultaneous negative values of magnetic and dielectric permeabilities (Double Negative, DNG bands) was analyzed. It is shown that changes in the dimensions of the connecting elements and the use of different materials significantly affect the position and width of the DNG bands. A controllable shift of the DNG region spanning 180–1300 MHz was identified through variations in the geometry and relative permittivity of the substrate. The obtained results may be useful for the design of metamaterials for microwave devices, including antennas and filters
