Abstract
Taking chicken manure containing antibiotic oxytetracycline (OTC) as the research object, nano-Fe2O3 with a concentration of 300 mg/kg TS and nano-C60 with a concentration of 100 mg/kg TS as carriers were used for a 55-day sequential batch mesophilic anaerobic digestion experiment. The gas production performance, chemical parameters, antibiotic content, enzyme concentration, and resistance gene changes during anaerobic digestion were analyzed to clarify the effect of nanoparticles on anaerobic systems containing antibiotic chicken manure and provide a reliable basis for pollution reduction capacity of livestock and poultry manure. The results showed that (1) adding nano-Fe2O3 and nano-C60 promoted anaerobic gas production in chicken manure with different concentrations of OTC. The cumulative gas production from days 1 to 10 was 2,234(T5) > 2,163(T4) > 1,445(T2) > 1,289(T3) > 1,220(T1) > 1,216(CK) mL. The cumulative gas production of T4 and T5 increased by 77.29 and 83.11%, respectively. The final cumulative gas production for each group was 3,712(CK), 3,993(T1), 4,344(T2), 4,447(T3), 4,671(T4), and 4,849(T5) mL. The final OTC residue concentrations were 15.25, 20.40, 56.56, 17.67, and 16.89 μg/L, with degradation rates of 98.31, 98.80, 98.29, 99.07, and 99.11% respectively; (2) antibiotic OTC increased the activities of dehydrogenase, amylase, protease, and urease, while adding nanoparticles increased the activities of dehydrogenase and amylase, with no significant impact on cellulase, urease, and protease activities; (3) antibiotic resistance gene (ARGs) of various types were found in groups T2, T4, and T5, with the multidrug resistance gene (ARGs)-Multidrug accounting for a high proportion of 33.54, 35.63, and 37.43%, respectively, while the proportions of the other four types MLS, tetracycline, glycopeptide, and peptide ranged from 8.18 to 12.98%.
Solving linear and nonlinear problems using Taylor series method
Authors: Veigend Petr , Nečasová Gabriela , Šátek Václav 
Published: July 2024

Abstract
The article deals with the solution of technical initial value problems. To solve such problems, an analytical or numerical approach is possible. The analytical approach can provide an accurate result; however, it is not available for all problems and it is not entirely suitable for calculation on a computer, due to the limited numerical accuracy. For this reason, the numerical approach is preferred. This approach uses ordinary differential equations to approximate the continuous behaviour of the real-world system. There are many known numerical methods for solving such equations, most of them limited in their accuracy, have a limited region of stability and can be quite slow to achieve the acceptable solution. The numerical method proposed in this article is based on the Taylor series and overcomes the biggest challenge, i.e. calculating higher derivatives. The aim of the article is therefore twofold: to introduce the method and show its properties, and to show its behaviour when solving problems composed of linear and nonlinear ordinary differential equations. Linear problems are modelled by partial differential equations and solved in parallel using the PETSc library. The parallel solution is demonstrated using the wave equation, which is transformed into the system of ordinary differential equations using the method of lines. The solution of nonlinear problems is introduced together with several optimisations that significantly increase the calculation speed. The improvements are demonstrated using several numerical examples that are solved using MATLAB software.
Chinese and English text classification techniques incorporating CHI feature selection for ELT cloud classroom
Authors: Wei Yufen 
Published: July 2024

Abstract
Although online cloud classroom teaching has been popular, the current English teaching cloud classroom has the defects of low information utilization and low information acquisition accuracy. To improve the information utilization and accuracy in teaching, a Chinese and English text classification algorithm is proposed. The algorithm is based on an improved Chi-squared test feature selection (CHI) algorithm. The performance of CHI is optimized by adding parameters such as word frequency, document coverage, and coefficient of variation to the CHI algorithm. According to the experimental results, the proposed algorithm achieved a recall of up to 1.0 under the Chinese dataset. Its accuracy rate was 0.49 higher than traditional CHI. Under the English dataset, the MO of the proposed algorithm reached 0.9. The results indicate that the proposed algorithm has reliable classification ability for both English and Chinese texts and has the potential to be applied to the English language teaching cloud classroom.

Published: July 2024

Abstract
The microservices architecture is widely used in modern businesses due to its ability to offer speed, efficiency, adaptability, autonomy, and usability. On the other hand, this architectural paradigm demands a well-designed infrastructure for optimal container and cluster utilization. Establishing version control and a solid continuous integration/continuous deployment (CI/CD) infrastructure becomes critical for accelerating software delivery to production and ensuring code alignment with best practices. This scientific investigation investigates the development of customized, specialized CI/CD procedures for software compliance, expanding its scope beyond traditional software delivery to include the complexities of design, testing, and server deployment. By integrating real-world examples from industry and reviewing crucial tools, the goal is to provide organizations with empirical information to navigate the difficulties of modern software development. The upcoming research seamlessly fits into the larger discussion, providing a deep understanding of sophisticated structures and their design. This interdisciplinary research combines the scientific principles governing microservices with the practical specifics of CI/CD methodologies, giving businesses a thorough understanding and practical insight into the tools needed to navigate the diverse landscape of modern software engineering. Among the main findings of this research is a suggestion for a new approach known as General repository compliance operations.

Improved sensitivity bounds for mediation under unmeasured mediator–outcome confounding
Authors: Sjölander Arvid , Waernbaum Ingeborg 
Published: July 2024

Abstract
It is often of interest to decompose a total effect into an indirect effect, relayed through a particular mediator, and a direct effect. However, these effect components are not identified if there are unmeasured confounding of the mediator and the outcome. We derive nonparametric bounds on the natural direct and indirect effects, and Cornfield inequalities that the unmeasured confounders must satisfy to explain away an “observed” effect. We demonstrate, analytically and by simulation, that these bounds and Cornfield inequalities are sharper than those previously proposed in the literature. We illustrate the methods with an application to cholestyramine treatment for coronary heart disease.
Online and offline physical education quality assessment based on mobile edge computing
Authors: Xu Ji 
Published: July 2024

Abstract
Every institution in China has undergone reform and piloting based on its unique situation to enhance the quality of instruction as a result of the ongoing advancement of the times and the educational idea in the information age. The effectiveness of education is increased by hybrid teaching, which combines offline and online approaches. It empowered educators and motivates learners to take responsibility for their learning. Classes in physical education (PE) that place a strong emphasis on training and technical performance are especially well-suited for hybrid instruction. This mode improves teaching abilities and supports the long-term growth of education. As a result, we offer an online and offline technique for assessing the quality of PE instruction that is relied on mobile edge computing (MEC). With the use of the target, index, weight, and standard assessments, this study builds a quality evaluation index (QEI) approach for PE that combines online and offline techniques. Assessing the corresponding significance of every index, factor, and cluster analysis compresses index elements. The weights of the QEIs for integrated instruction are determined using MEC. The efficacy of combined PE is assessed using the fuzzy logic-based comprehensive assessment methodology. According to the analytical model, this strategy increases teaching quality while reducing costs and mistakes and improves assessment effectiveness. The experimental results proved that the proposed model has provided an accuracy of 95.98%.

Published: July 2024

Abstract
This article presents a non-linear mathematical model that captures the dynamics of drinking prevalence within a population. The model is analyzed under an optimal control framework, dividing the total population into four compartments: susceptible, heavy drinker, drinker in treatment, and recovered classes. The model’s validity is affirmed through considerations of positivity, boundedness, reproduction number, stability, and sensitivity analysis. Stability theory is employed to explore both local and global stabilities. Sensitivity analysis identifies parameters with a significant impact on the reproduction number (

increase in the threshold quantity. The study introduces an optimal control strategy that involves awareness campaigns and treatment as control variables. These controls aim to minimize the number of heavy drinkers while maximizing the number of recovered individuals. Pontryagin’s maximum principle is used to solve optimal control problems. Additionally, the research explores various parametric settings for each compartment, enriching the study environment. The effectiveness of the proposed control scheme is evaluated through rigorous numerical simulations, highlighting its competitive edge. The results, validated using MATLAB simulations, are detailed throughout the article.

Разработана математическая модель потока водорода из газовых смесей через стенки капиллярных трубок из металлического никеля, учитывающая неоднородность парциального давления водорода вдоль длинной трубки, а также неоднородность температуры на разных участках трубки. С помощью модели на основе экспериментальных данных рассчитаны кинетические параметры транспорта водорода в диапазоне температур 600–850 °C и диапазоне парциальных давлений водорода 0.1–1.0 атм. Модель может быть использована при проектировании мембранных модулей сепарации водорода из газовых смесей для расчета длины единичных мембран, их количества и оптимальной скорости потока водородсодержащей смеси через мембрану.
A mathematical model of the flow of hydrogen from gas mixtures through the walls of capillary tubes made of metallic nickel has been developed, taking into account the inhomogeneity of the partial pressure of hydrogen along a long tube, as well as temperature nonuniformity in different regions of the tube. Using the model and relying on experimental data, the kinetic parameters of hydrogen transport were calculated within the temperature range of 600–850 ºС and the hydrogen partial pressure range of 0.3–0.8 atm. The model can be used in the design of membrane modules for hydrogen separation from gas mixtures to calculate the length of individual membranes, their number, and the optimal flow rate of the hydrogen-containing gas mixture through the membrane.
