Формулювання проблеми. Відомо формули, за якими можна знайти похідну кожного елемента багатовимірного відображення. При цьому досить рідко на практиці використовують матрицю Якобі - першу його похідну, матрицю Гессе – другу похідну скалярної функції кількох змінних, тощо. В той самий час застосування матриць як технічного апарата при розв’язуванні подібних задач виявляється зручним і ефективним. На цьому шляху все ж виникають труднощі, наприклад, при матричному запису похідної від матриці. Виявляється, що для адекватного опису подібних конструкцій варто використовувати тензорні добутки матриць, де разом зі звичайними матрицями та векторами працюють з формальним вектором - лінійним оператором, елементами якого є оператори частинних похідних. При цьому формули для похідної довільного і диференціалу порядку від вектор-функції стають зрозумілими і прозорими.
Матеріали і методи. Для дослідження похідних високих порядків багатовимірних відображень широко використовується метод тензорних (кронекерівських) добутків матриць. При цьому похідна довільного порядку вектор-функції визначається як тензорний степінь формального диференціального оператора першого порядку – транспонованого вектора-градієнта. Дія таких тензорних виразів на вектор-функцію дає її похідну відповідного порядку. Це дає змогу описати мовою матриць конструкцію похідних, що на якісному рівні відрізняється від знаходження частинних похідних від кожної компоненти багатовимірного відображення.
Результати. За допомогою використання тензорних добутків матриць доведено і детально виписано формули для першої і другої похідних вектор-функцій, а також вказано, як знаходиться похідна довільного порядку. В класичних курсах математичного аналізу, як правило, виписуються матриця Якобі багатовимірного відображення і матриця Гессе (друга похідна) скалярнозначної функції багатовимірного аргументу. В пропонованій статті показано алгоритм знаходження довільної похідної як оператора, що діє в тензорному добутку лінійних просторів, що дає змогу краще усвідомити цю важливу конструкцію математичного аналізу.
Висновки. Широке застосування тензорних операцій, в яких діє також формальний вектор-оператор похідної першого порядку виявляється дуже ефективним. Більш того, на цьому шляху вдається показати структуру, з’ясувати, елементами яких лінійних просторів є похідні. На цьому шляху зразу вдається одержати усі похідні шуканого порядку, а не кожну частинну похідну окремо.
DETERMINING THE DENSITY AND MOLAR MASS OF AIR IN A HOME EXPERIMENT
Authors: Podlasov Serhii 
Published: June 2024

Formulation of the problem. Experimental research is an integral part of physics education. During distance learning, students can carry out hands-on experiments only at home. Modern smartphones, equipped with various sensors, offer significant capabilities for this purpose. The literature offers quite extensive descriptions of experiments aimed at determining mechanical, acoustic, and optical quantities using smartphones. At the same time, insufficient attention has been paid to determining gas parameters that can be measured using the pressure sensor embedded in smartphones. Therefore, the relevant task is to develop a methodology for experimenting to determine the density of air and its molar mass at home using a pressure sensor.
Materials and methods. To achieve the objective of the study, we used the analysis of the curriculum of the course "General Physics for Bachelor of Engineering", a review of the methodological instructions for performing laboratory work in the section "Molecular Physics and Thermodynamics" of the physics course of technical universities, a review of the literature on the topic of the study, and an analysis of the results of student research on the dependence of air pressure on altitude. We also surveyed students about the possibility of conducting the research at home and their interest in conducting other experiments using a smartphone.
Results. The methodology for determining the density and molar mass of air was developed based on the results of a study of the pressure-height dependence. It is shown that it is necessary to perform statistical processing of experimental data to estimate the sought quantities. The experimental results allowed us to obtain values of density and molar mass of air that show a good correlation with the tabulated values.
Conclusions. Studying the pressure-altitude relationship using a smartphone and the PhyPhox application allows for fairly accurate calculations of air density and molar mass. According to the survey results, students responded positively to conducting home experiments using smartphones.
Fast Probabilistic Seismic Hazard Analysis through Adaptive Importance Sampling
Authors: Houng Soung Eil , Ceferino Luis 
Published: June 2024

Probabilistic Seismic Hazard Analysis (PSHA) traditionally relies on two computationally intensive approaches: (a) Riemann Sum and (b) conventional Monte Carlo (MC) integration. The former requires fine slices across magnitude, distance, and ground motion, and the latter demands extensive synthetic earthquake catalogs. Both approaches become notably resource intensive for low-probability seismic hazards, where achieving a COV of 1% for a 10−4 annual hazard probability may require 108 MC samples. We introduce Adaptive Importance Sampling (AIS) PSHA, a novel framework to approximate optimal importance sampling (IS) distributions and dramatically reduce the number of MC samples to estimate hazards. We evaluate the efficiency and accuracy of our proposed framework using Pacific Earthquake Engineering Research Center (PEER) PSHA benchmarks that cover various seismic sources, including areal, vertical, and dipping faults, as well as combined types. Our approach computes seismic hazard up to 3.7×104 and 7.1×103 times faster than Riemann Sum and traditional MC methods, respectively, maintaining COVs below 1%. We also propose an enhanced approach with a “smart” AIS PSHA variant that leverages the sampling densities from similar ground motion intensities. This variant outperforms even “smart” implementations of Riemann Sum with enhanced grid discretizations by a factor of up to 130. Moreover, we demonstrate theoretically that optimal IS distributions are equivalent to hazard disaggregation distributions. Empirically, we show the approximated optimal IS and the disaggregation distributions are closely alike, e.g., with a Kolmogorov–Smirnov statistic between 0.017 and 0.113. This approach is broadly applicable, especially for PSHA cases requiring extensive logic trees and epistemic uncertainty.

Authors: Hamza Fadhil Hamza  , Mohammed Jawad Al-Mudhafar May 
Published: June 2024

Pathogenic microorganisms are becoming more and more resistant to antimicrobial agents. So the synthesis of new antimicrobial agents is very important. In this work, new 5-fluoroisatin-chalcone conjugates 5(a–g) were synthesized based on previous research that showed the modifications of the isatin moiety led to the synthesis of many derivatives that have antimicrobial activity. 4-aminoacetophenone reacts with 5-fluoroisatin to form Schiff base (3), which in turn reacts with two different groups of aromatic (carbocyclic and heterocyclic) aldehydes 4(a–g) separately to form the final compounds 5(a–g). Proton-nuclear magnetic resonance (¹H-NMR) and Fourier-transform infrared (FT-IR) spectroscopy were used to confirm the chemical structures of the newly prepared compounds. Finally, the final compounds, 5-fluoroisatin-chalcone conjugates 5(a–g), were screened for their antimicrobial activities and compared with three different references: vancomycin, ciprofloxacin, and fluconazole. They appeared to be good candidates as antibacterial agents against E. coli and S. aureus as well as antifungal agents against C. albicans. In general and for comparison, the antifungal activity of the final compounds 5(a–g) was more potent than their antibacterial activity. Finally, for the antimicrobial activity, the most active compound of these series was compound 5e, while compound 5g was the least active one.
Application of Some Physical Seed Treatment Methods to Increase Germination of the Genus Catalpa Scop.
Authors: Aitymov A.K. 
Published: June 2024

To increase the production volume of planting material for ornamental plants in the conditions of Central Kazakhstan, the selection of pre-sowing treatment methods for seed material becomes relevant. The use of safe and effective germination activators accelerates the biological processes of plant growth. The aim of the research was to study the impact of physical methods on the germination of Catalpa speciosa seeds as relatively safe methods of seed material activation. The seed treatment was carried out in three ways: the effect of laser irradiation, magnetic fields for 24, 72 hours, and twenty-four-hour aeration. A different response of seedlings to physical factors of influence was noted. The effect of the magnetic field allowed to increase germination by an average of 10 % compared to the control group. The impact of laser irradiation for 1‒4 minutes on the growth of Catalpa speciosa seedlings was less significant. Aeration had a positive effect on the energy of seed germination. Thus, to increase the germination of seedlings during early sowings of Catalpa speciosa seeds, it is promising to use the influence of the magnetic field and aeration.

Published: June 2024

Many researchers are currently investigating carbon dioxide capture and storage since it is suppressing the global warming phenomenon. Aqueous carbon dioxide chemical absorption is the most effective method. The present study incorporates the applicability and performance of blended alkanol amine solutions monoethanolamine (MEA) with diethylenetriamine (DETA) as a chemical blended absorbent investigated in a pilot scale column packed randomly with Rashing rings. The effect of operating conditions on absorption performance was examined. The performance investigation is given in terms of the overall mass transfer coefficient and carbon dioxide capture efficiency (ƞ). Typically, DETA: MEA with a mass ratio of 1:1 and total mass concentration of 30 % wt. could provide the highest KGav with a value of 0.1572 (kmol/(m3*Kpa*hr)) and ƞ with a value of 98.79 %. While at the same condition in terms of liquid and gas rate, with DETA: MEA in the blending mass ratio 0.25:1, the KGav and ƞ values equal to: 0.1198 (kmol/(m3*Kpa*hr)) and 96.37%, respectively. Based on these findings, it is reasonable to assume that diethylenetriamine, a solution of alkanol amines, would serve as an efficient blending absorbent for carbon dioxide removal.

The purpose of the study is to optimize the immediate results of stenting of the main trunk of the left coronary artery (LCA) in patients with coronary heart disease (CHD) using intravascular imaging methods and modern technological approaches.Materials and methods. We present the experience of 186 consecutive patients with coronary artery disease in whom stenting of the Left Main (LM) coronary artery was performed.Results. Patients were divided into 2 groups – group I, «historical» (100 patients), where the intervention was performed without the use of intravascular imaging methods and proximal optimization methods (POT), and group II, which consisted of 86 patients in whom LM stenting was performed using intravascular imaging and modern methods of optimizing the stented segment. In general, groups I and II were comparable. About 20 % of patients had an isolated LM lesion. In other cases, according to the results of coronary angiography, multivessel lesions of the coronary vessels were recorded in the patients. The localization of the lesion was defined as ostial in 7.5 %, stem – 6.9 %, and distal with the involvement of LAD&CX in 85.6 %. Stenting with 1 stent was used in 132 patients (71 % of cases).Analyzing the final size of the stented LM segment in the groups, we noticed, that in group I, this figure was 3.41±0.41 mm, while in group II it was 3.97±0.61 mm (p<0.0001). In 3 patients of group I in 30 day period cardiac death were recorded, in the group II there were 2 (2.3 %) cases of LM dissection treated with additional stent implantation.In 3 patients (3 %) group I sudden cardiac death was registered in the 30-day period. In group II, there were 2 (2.3 %) cases of ossification, which were resolved by additional stent implantation.Conclusions. Intravascular imaging to assess the size and results of the intervention, as well as the use of the POT technique, significantly improves the positioning of the stent in the artery and provides a significantly larger diameter of the stented LM. Adequate optimization of the size of the stented LM can be obtained only with the help of intravascular imaging methods.
