Authors: Abdurakhmonov Amirshokh , Tusnin Alexander
Published: August 2023

Wide application in the construction of thin-walled steel rods of an open profile requires taking into account the peculiarities of the work of load-bearing structural elements under the action of the entire complex of loads. For a number of rod systems consisting of I-beam profiles, it is impossible to exclude torsion under the action of compressive forces, which leads to the appearance of additional normal stresses in the profile. In this regard, it is necessary to study the actual operation of compressed I-beams under the action of torsional loads. The bearing capacity of a compressed I-beam profile strut with constrained torsion is considered. The method of conducting an experimental study of a centrally and off-center compressed I-beam profile strut under the action of longitudinal force and bimoment is presented. The analysis of the effect of the bimoment on the bearing capacity of a centrally and off-center compressed thin-walled rod of an open profile with constrained torsion is performed. The bearing capacity of the centrally and off-center compressed I-beam profile strut from the action of longitudinal force and bimoment was experimentally determined, which was compared with the results of numerical calculations in finite element formulation, taking into account geometric and physical nonlinearity in conditions of constrained torsion. According to the results of the experiment, the possibility of using numerical modeling to assess the stability of centrally and off-center compressed thin-walled rods was established. open profile with constrained torsion under various schemes of external force.

Authors: Kirianova Ludmila
Published: August 2023

The paper considers an inhomogeneous partial differential equation of hyperbolic type containing both second order partial derivatives and fractional derivatives of an order lower than the second order on the spatial variable. The fractional derivative is understood in the Riemann-Liouville sense. The paper first part presents analytical solution of the boundary value problem of the first kind with arbitrary initial conditions of the equation in question by the Fourier method (separation of variables). The solution is given in the form of two functions, one of which characterizes the stationary state of the process, and the second is treated as a deviation from the stationary state. The second function is found using eigenfunctions and eigenvalues of the corresponding two-point Dirichlet problem, while the first is written out as a Mittag-Leffler function. In the second part of the paper, the solution application examples of the boundary value problem of the equation under consideration in modelling the behaviour of polymer concrete based on polyester resin (dian and dichloroanhydride-1,1-dichloro-2,2-diethylene) under load are considered. The examples give specific values for the parameters of the equation and graphs of the solutions and the error resulting from replacing a series by its partial sum. All calculations were performed in the MATLAB application package.
Accounting for tension in transverse bending of statically indeterminate elastic rods
Authors: Konstantin Modestov , Sergey Saiyan , Artyom Erokhin , Daniil Sinyakin
Published: August 2023

For statically indeterminate rod structures with excess constraints in the horizontal direction, tension forces arise under transverse loading, significantly affecting the stress-strain state of the rods compared to similar rods caused by bending alone (in the absence of excess longitudinal constraints). This fact requires computational analysis, and in this work, analytical dependencies of the deflection of the rod and the magnitude of tension due to transverse loading were obtained for cases with clamped-clamped and two hinged supports for the ends of the rod based on the derived Lagrangian principles of mechanics. Based on analytical dependencies, a graphical method was developed to determine the axial force under given stiffness and transverse loading for the considered computational cases. These results can be applied to the study of the stress-strain state of rod structures with excess constraints in the horizontal direction under transverse loading.

Authors: Dolgushev Timothey , Dolgusheva Vera
Published: August 2023

The development of the mineral resource base of the Arctic region of the Russian Federation has become possible, among other things, due to the increase in the duration of the navigation period and the improvement of navigation conditions due to climatic changes. The development of oil and gas reserves in this region creates the need to provide marine transport infrastructure, and, consequently, the development of existing and construction of new port hydraulic structures. The author of the article reviewed the data of satellite observations of the sea level anomaly in the area of the construction of the Indiga port in the southeastern part of the Barents Sea from October 1992 to September 2022. It is shown that there is a stable positive trend towards sea level increasing over a period of 30 years, which indicates that a number of data series used in constructing probability curves according to regulatory methods are nonstationary. The lack of consideration of climatic changes in the level regime leads to incorrect results of calculations of water levels of a given probability according to current regulatory methods, therefore, the article deals with an example of considering the data of climatic modeling of the level regime of the Indiga port area for the life cycle of port hydraulic structures. Dividing the service life of the structure into stages, which consider the change in the marks of the structure or its absence, depending on the actually observed increase in the level of the water area, will ensure the reliability and safety of operation throughout the life cycle. The reserves laid down during the design and the creation of long-term reconstruction plans will make it possible to carry out work on raising the berth marks for berthing structures and the marks of the upper structure of protecting structures with the least expenditure of material resources and time.

Authors: Bubnov Danila , Volnushkina Ksenia , Bryanskaya Yuliya
Published: August 2023

Aging water supply and wastewater pipeline systems suffer from corrosion and damage. Trenchless restoration methods extend their lifespan and reduce repairing costs. However, there is no standard method for determining the hydraulic characteristics of restored pipelines, making it challenging to assess the feasibility of using different materials for restoration. This article focuses on changes in hydraulic characteristics after restoring pipelines with glass fiber and synthetic felt hoses. The study uses Bernoulli’s equation and the Chezy formula to estimate changes in the flow capacity of pipelines. Standard values for slopes, flow rates, and filling rates were used to calculate the hydraulic resistance coefficient, Chezy coefficient, and flow rate after laying polymer hoses. The results show that the flow capacity of restored pipelines increases, and there is no need for further hydraulic calculations to confirm the absence of a reduction in pipeline capacity after restoration. Therefore, trenchless restoration methods can be considered as effective means to extend the lifespan of aging pipeline systems and reduce engineering repairs costs.

Published: August 2023

High-level synthesis (HLS) is utilized for high-performance and energy-efficient heterogeneous systems designing. HLS is assist in field-programmable gate array circuits designing where hardware implementations are refined and replaced in target device. However, the power-process-voltage-temperature-delay (PPVTD) variation in VLSI circuits undergoes many problems and reduced the performance. In order to address these problems, C4.5 with eXtreme Gradient Boosting Classification based High Level Synthesis (C4.5-XGBCHLS) Method is designed for afford better runtime adaptability (RA) with minimal error rate. VLSI circuits are designed using the behavioral input and results are measured at running condition. When VLSI circuit’s results get reduced, the language description of the circuit is considered as an input. Then, compilation process convert high level specification into Intermediate Representation (IR) in control/data flow graph (CDFG). CDFG computes data and control dependencies among operations. eXtreme Gradient Boosting (XGBoost) Classifier is exploited in C4.5-XGBCHLS method to classify the error causing functional unit (FU) with minimal error rate. XGBoost Classifier exploited C4.5 decision tree as base classifier to enhance classification of error causing FU in VLSI circuits. After that, FU gets allocated in place of error causing FU from functional library based on the design objectives and PPVTD variations. Finally, operation scheduling and binding process is executed for register transfer level (RTL) generation to form VLSI circuits with improved RA. The simulation results shows that the C4.5-XGBCHLS method enhances the performance of functional unit selection accuracy (FUSA) with minimal error rate (ER) and circuit adaptability time (CAT).

The existing literature has not yet proposed any multi-objective DEA model till date. However, such model is in demand because most of the real life problems consist of multiple stages. The proposed model has also considered dissimilar intermediate weights. The proposed model has been applied to a multi-stage insurance problem with two input variables, two intermediate variables and two output variables in order to establish the effectiveness of the proposed model. The proposed model is an algorithmically complex problem and therefore a hybrid Multi-Objective Genetic Algorithm has been applied in order to solve the proposed model.

Published: August 2023

In our day-to-day life, milk is a fundamental component that is rudimentary for many food products. Consuming milk regularly is very important because it is a mixture of various macro and micronutrients and is a source of proteins, fats, carbohydrates, and vitamins. Particularly in our nation, women’s empowerment and milk production are closely related. Furthermore, rural Indian communities rely heavily on small holder dairy farms for their livelihoods, and women play an important role in milk production. The dairy sector is estimated to contribute around 6% of the country’s agricultural GDP, with the value of milk production in India exceeding 200 million ton by the year 2023 [1]. Milk is a highly perishable commodity, when not handled properly it is susceptible to microbial spoilage. The milk after production must be processed properly to retain its quality till consumption. Nowadays, many milk vendors are adulterating the milk for financial gain. Consumers have the rights to obtain good and safe milk, as it is largely consumed by people of all age groups. Supply chain process of a small holder dairy farming has been examined recently in Salem, Tamil Nadu, India and it has been observed that the current process in dairy involves the accumulated milk from dairy farmers are being poured into the milk cane, then being detected and sent to a larger container where it is mixed with all the other milk. In most cases, it would be impossible to separate fresh milk from un-fresh milk. Therefore, the objective of this research work aims to develop a Blockchain and IoT based solution for milk procurement and adulteration detection there by providing a complete milk traceability data to the consumers from production to consumption, and establishing a trust in providing quality milk to the society.

Published: August 2023

This paper addresses essential hematology that is automatically segmenting blood cells. We consider a unique hybrid ellipse fitting (EF) based blood-cell segmentation technique that combines noniterative-geometric and algebraic approaches to overcome current concerns with inaccurate seed-point identification, noise, and over-segmentation. We propose a hybrid EF approach based on least-squares (LS) for improved segmentation performance. To enhance segmentation while retaining a reasonable EF, we advise utilizing the specified value for the residue offset and computing the minor and major axes using the residue and offset residue variables. Different evaluation matrices such as precision, and F1 score are used where our approach performs better than existing EF algorithms. This approach is computationally effective and might be used in cybernetics and medicine.

This paper presents a new study to use pre-trained language models based on the transformers for Arabic grammatical error detection (GED). We proposed fine-tuned language models based on pre-trained language models called AraBERT and M-BERT to perform Arabic GED on two approaches, which are the token level and sentence level. Fine-tuning was done with different publicly available Arabic datasets. The proposed models outperform similar studies with F1 value of 0.87, recall of 0.90, precision of 0.83 at the token level, and F1 of 0.98, recall of 0.99, and precision of 0.97 at the sentence level. Whereas the other studies in the same field (i.e., GED) results less than the current study (e.g., F0.5 of 69.21). Moreover, the current study shows that the fine-tuned language models that were built on the monolingual pre-trained language models result in better performance than the multilingual pre-trained language models in Arabic.

This information is then passed to the GTTS system, which generates audio alerts to notify the user of the presence of an obstacle and its location. The audio alerts are generated in a natural-sounding voice to provide the user with clear and concise information. To evaluate the effectiveness of our proposed system, we conducted experiments with visually impaired individuals in real-world scenarios. The results show that our system can significantly improve obstacle detection and avoidance performance compared to traditional methods. The participants reported high levels of satisfaction with the system’s performance and ease of use.

Published: August 2023

This note is concerned with the rigorous justification of the so-called hard congestion limit from a compressible system with singular pressure towards a mixed compressible-incompressible system modeling partially congested dynamics, for small data in the framework of BV solutions. We present a first convergence result for perturbations of a reference state represented by a single propagating large interface front, while the study of a more general framework where the reference state is constituted by multiple interface fronts is announced in the conclusion and will be the subject of a forthcoming paper. A key element of the proof is the use of a suitably weighted Glimm functional that allows to obtain precise estimates on the BV norm of the front-tracking approximation.

In the present paper, we investigate several cubic equations of state widely used in the literature, for which we are able to construct analytically the complete law. In order to describe two-phase flows, we use Maxwell's construction, which amounts to consider pure phases and a mixture zone at saturation. The parameters appearing in the different equations of state are fitted in order to be precise in the saturation zone at high pressures. The different laws are then compared in a large range of pressures, showing the best accuracy of Clausius equation of state.

Ein besonders hohes Risiko für Toxizität besteht bei Patienten mit zusätzlicher Gabe von Anthrazyklinen, hohen Strahlendosen (> 25 Gy Mean Heart Dose, MHD), Krebserkrankung in
Kindesalter sowie mehreren zusätzlichen kardiovaskulären Risikofaktoren. Insbesondere diese Patienten sollten langfristig kardiologisch nachuntersucht werden. Hierzu gehört die
transthorakale Echokardiografie (mindestens alle 5 Jahre) und die nicht invasive Koronardiagnostik (alle 5–10 Jahre).
Immuntherapien: Was muss der Kardiologe wissen?
Authors: Totzeck Matthias
Published: August 2023

Zu den wichtigsten Immuntherapeutika in der Onkologie zählen die Immun-Checkpoint-Inhibitoren (ICI). ICI konnten die Prognose verschiedener Krebsarten signifikant verbessern. Im Gegensatz
zu konventionellen Therapien üben ICI Antitumorwirkungen aus, indem sie das körpereigene Immunsystem aktivieren, welches dann wiederum Krebszellen aktiv eliminieren kann. Es gibt 3
zugelassene ICI-Klassen: Inhibitoren, die auf das zytotoxische T-Lymphozyten-assoziierte Antigen 4 (CTLA4), den programmierten Tod 1/den programmierten Todesliganden 1 (PD1/PDL1) und das
Lymphozytenaktivierungsgen 3 (LAG3) abzielen. ICI sind häufig mit unterschiedlichen Toxizitäten verbunden, die als immunvermittelte unerwünschte Ereignisse bekannt sind (engl. Immune-related
Adverse Events, irAE). Akute kardiovaskuläre immunvermittelte Nebenwirkungen wie z. B. die Myokarditis sind selten, können aber fatale Folgen für Lebensqualität und das Überleben haben,
sodass eine frühzeitige Diagnose und Therapie entscheidend sind.

Published: August 2023

Fortschritte bei der Behandlung von Krebserkrankungen haben zu einer erheblichen Verbesserung der Prognose und einer zunehmenden Bedeutung kardiotoxischer Nebenwirkungen infolge einer
onkologischen Therapie geführt. In diesem Zusammenhang hat sich die Kardioonkologie als neue Subspezialisierung etabliert. Die Kardioonkologie verfolgt das Ziel, die Prävention und
Behandlung kardiovaskulärer Erkrankungen bei Krebspatienten zu verbessern. Die erstmals im Jahre 2022 publizierten ESC-Leitlinien zum Thema Kardioonkologie beinhalten umfassende Empfehlungen
zur kardiovaskulären Risikostratifizierung, Überwachung, Diagnose und Primärprävention im Kontext onkologischer Erkrankungen und Therapien.

Asymmetric oxidation reactions have significantly benefited from bishydroxamic Brønsted acid ligands, and they can proceed with remarkable stereoselectivity. Designing and synthesizing these ligands are essential for achieving high enantioselectivity in metal-catalyzed oxidation reactions. This paper presents a straightforward method for synthesizing novel phenyl-ring-centric bishydroxamic acids (BHA). A preliminary analysis of Ti-BHA-catalyzed reactions resulted in asymmetric epoxides with an exceptional enantiomeric excess (>99% ee). At the same time, ongoing experiments aim to improve the reaction conversion for enhanced overall efficiency.
Cervicovaginal Microbial–Immune State and Group B Streptococcus Colonization in Pregnancy

Published: August 2023

Objective Maternal colonization with Group B Streptococcus (GBS) is a significant risk factor for serious neonatal morbidity. There are limited data on how the cervicovaginal (CV) microbiota and host immune factor β-defensin-2 might influence GBS colonization in pregnant individuals. This study sought to determine if the CV microbiota is associated with GBS colonization in pregnant individuals, and if β-defensin-2 modifies this relationship.

Study Design This was a secondary analysis of a prospective cohort study of pregnant individuals with singleton pregnancies who had CV microbiota specimens analyzed at 16 to 20, 20 to 24, and 24 to 28 weeks' gestation, along with a third trimester GBS rectovaginal (RV) culture (n = 492). Microbiota data were analyzed with 16S rRNA gene sequencing and classified into community state types (CSTs). Log-binomial multivariable regression was used to model associations between CST and GBS RV status and to calculate risk ratios. β-defensin-2, an immune factor known to modulate the relationship between CST and pregnancy outcomes, was examined as an effect modifier.

Results Of 492 individuals, 34.3% were GBS RV + . Compared with individuals with CST I at 16 to 20 weeks, individuals with CST IV-A and CST II had a significantly elevated relative risk of subsequent GBS RV+ status. When stratified by high and low β-defensin-2 levels, β-defensin-2 was found to be an effect modifier of the association between CST IV-A and GBS RV+ status. In individuals with low β-defensin-2 levels, CST VI-A was associated with GBS RV+ status, but among individuals with high β-defensin-2 levels, there was no such association (interaction p-value = 0.03).

Conclusion Pregnant individuals with CV microbiota characterized by CST IV-A and CST II had significantly elevated risk of GBS RV colonization in the third trimester compared with those with CST I, and β-defensin-2 was an effect modifier of the association between CST IV-A and GBS RV+ status. Future research should investigate if manipulation of the CV microbiota can prevent GBS colonization, thereby reducing intrapartum antibiotic prophylaxis and the risks of neonatal GBS infection.

Key Points
The coexistence of nationalism, Westernization, Russification, and Russophobia: facets of parallelization in the Russian invasion of Ukraine
Authors: Boman Björn
Published: August 2023

Parallelization theory complements earlier concepts in cultural and political history by focusing on the coexistence of seemingly contradictory patterns in various localities, such as segregation/integration of migrants in Europe and the USA, polarization/hybridization in Korea and Ukraine, and secularization/the resurgence of religions in countries like Malaysia and Sweden. The current article examines the parallel presence of Ukrainian nationalism/Westernization and Russification/Russophobia before and in the aftermath of the 2022 Russian invasion of Ukraine. The argument is bolstered by both Russian, Ukrainian, and Western media sources, showing how and why these seemingly conflicting tendencies coexist.
