EVALUATING THE FUNCTIONING EFFECTIVENESS OF SENSOR GROUND-TO-AIR NETWORK USING MULTIPLE UAVS LAYERS AND DIRECTIONAL ANTENNAS
Authors: Sushyn Ihor , Ivashchev Daniil , Lysenko Olexandr
Published: December 2024

Background. Based on the theoretical and practical (using Atoll) calculation of radio communication lines and antenna devices were estimated the main network parameters (throughput, length of the data transmission route, delays, number of network elements) of proposed ground to air network (GAN) architecture.
Objective. The purpose of the work is to evaluate the effectiveness of mobile networks with directed action sensors using UAVs at different levels.
Methods. Simulation modelling of two mathematical models and their comparison using MATLAB software.
Results. It is shown that the throughput decreases with the increase of the data transmission route, while the delay and the number of network elements increase in accordance with the previous study. Changing the location of the nodes also affects the parameters evaluated, so 10,000 measurements were made to obtain the required amount of statistical data. Two mathematical models were created. The first model is based on an existing mobile omnidirectional sensor network using a single UAV layer while the second one is based on a mobile network of directional sensors using two levels of UAVs. In both models, the data was transmitted from the nodes to the pseudo-satellite. In the proposed model, the following average values were achieved: throughput - 852071 bits/s, number of network elements - 4.4, route length - 33673 meters.
Conclusions. According to the obtained results, it can be argued that the proposed two-level UAV location model using directional sensors can be effectively used to maintain the connectivity of a mobile sensor network with the achievement of a gain in the evaluated indicators.

Authors: Globa Larysa , Kartashov Anton
Published: December 2024

Background. Multi-cloud environments present complex challenges in optimal resource allocation and provider selection. Previous research has established a comprehensive ontological model and evaluation criteria for distributed data storage, however efficient provider selection remains a significant challenge due to the dynamic nature of cloud services and the multitude of interdependent factors affecting performance and cost-effectiveness.
Objective. The purpose of the paper is to develop and validate a sophisticated optimization function for cloud provider selection in multi-cloud environments, incorporating both Reinforcement Learning (RL) and Multi-Objective Evolutionary Algorithms (MOEAs) to address the complexity of provider selection while considering multiple competing objectives and constraints.
Methods. The research employs an ontological approach to formalize domain concepts, relationships, and properties in multi-cloud environments. Additionally, an optimization function is developed incorporating multiple weighted criteria derived from the established ontological model. The study focuses on the implementation of the RL algorithm to adapt to dynamic changes in cloud provider characteristics and integration of MOEAs to handle multiple competing objectives as well as providing a comparative analysis with traditional selection methods and alternative optimization approaches for multi-cloud storage settings.
Results. The proposed ontological model successfully formalizes the domain's concepts, relationships, and properties in multi-cloud environments. The optimization function demonstrates effectiveness in selecting the most suitable public cloud provider based on the proposed features, enhancing data management practices automation and decision-making processes.
Conclusions. The developed optimization function and suggested methodology significantly advance the state-of-the-art in distributed multi-cloud data storage. The integration of RL and MOEAs provides a robust framework for addressing the complexity of multi-cloud environments while offering superior performance compared to existing approaches. The methodology successfully balances multiple objectives while adapting to dynamic changes in cloud provider characteristics.
BASE STATION POWER BACKUP SCHEDULING FOR NETWORK PROVIDERS BY A THREE-PERSON DYADIC GAME
Authors: Romanuke Vadim
Published: December 2024

Background. Recently reliable telecommunication has been challenged due to power grid instability and temporary blackouts. There is a strong need for optimizing the base station power backup for telecommunication network providers.
Objective. The purpose of the paper is to substantiate a game model of optimizing the base station power backup for three major telecommunication network providers and determine the best strategy. The optimization is based on payoff symmetry, rather than equilibrium.
Methods. There are only two pure strategies at the provider — to apply the power backup or ignore applying, whenever needed. The latter means avoiding additional expenses for the provider while applying the power backup requires additional expenses. The cost of applying the power backup is set to a conditional unit. It is further assumed that, if only one provider does not apply the power backup, it does not affect the quality of service (QoS). When there is no backup at all, QoS worsens significantly, users subsequently seek for alternative telecommunication services, and shortly every provider loses the 3 units.
Results. The provider’s expected payoff, being treated as a loss, is minimized over the set of symmetric mixed situations, where the provider’s mixed strategy is the no-backup probability. The base station power backup best strategy is realized by turning the power backup off with an irrational probability whose value lies between 0.05904144 and 0.05904145. It is more likely that the backup state switch is possible at definite time intervals usually counted in hours or days.
Conclusions. The best strategy allows saving the power backup for 5.904 % of the temporarily-off-the-grid period by saving 2.9 % of expenses for the backup, which does not worsen the QoS. Whenever the amounts of providers’ expenses, costs, and losses are changed, the best strategy is determined in the same way it has been found.
Luteinizing hormone-releasing hormone receptor agonists and antagonists in prostate cancer: effects on long-term survival and combined therapy with next-generation hormonal agents
Authors: Zhao Jinge , Chen Junru , Sun Guangxi , Shen Pengfei , Zeng Hao
Published: December 2024

Prostate cancer is a leading cause of cancer-related death in men worldwide. Luteinizing hormone-releasing hormone receptor (LHRH-R) agonists and antagonists are known to achieve castration-level testosterone suppression; however, long-term data comparing the survival benefits of these therapies are insufficient to inform treatment decisions. Furthermore, the advent of next-generation hormonal agents (NHAs), such as abiraterone and enzalutamide, have shifted the paradigm of managing prostate cancer. Although LHRH-R agonists and antagonists remain the cornerstone treatment across various stages of prostate cancer, they are increasingly administered with NHAs, because the combination treatment confers a survival advantage. Nevertheless, the differences in efficacy and safety profiles among various combinations of LHRH-R agonists and antagonists and NHAs remain unclear. Hence, this narrative review is aimed at providing a comprehensive overview of the long-term outcomes of various LHRH-R agonists and antagonists. Key data from major clinical studies are summarized, categorized by disease stage. LHRH-R agonists and antagonists, particularly goserelin, have demonstrated long-term survival benefits in patients with localized and locally advanced prostate cancer. The clinical outcomes of different LHRH-R agonists and antagonists in combination with NHAs have also been evaluated. Among the various combinations, goserelin plus abiraterone appears to have a manageable safety profile with relatively low rates of hot flushes and fatigue. Overall, long-term survival data and safety profiles should be considered in selecting optimal combination therapies for prostate cancer treatment.
RECURRENT SEMIOSIS IN THE DISCOURSE OF DRAMA AS A MARKER OF COGNITIVE-PRAGMATIC MODIFICATIONS
Authors:   Ryazan State University named for S. Yesenin, Loginova E.G.
Published: December 2024

The paper examines the cognitive and communicative potential of recurrent semiosis in the discourse of drama. The author assumes that different types of repetition in plays mark changes in the pragmatic parameters of the communicative situation: spatial and temporal parameters, modes of discourse, standpoint (objective, subjective; emotionally coloured or neutral), participants and their qualities (attitudes to one another, mood, personal involvement with the topic, etc.). The analysis of 10 plays written by Russian and British playwrights (H. Pinter, S. Beckett, T. Stoppard, A. Volodin, А. Vаmpilov, A. Kazantsev, N. Sadur, N. Kolyadа) leads to highlighting a set of markers and indicators matching up to the cognitive techniques that bring pragmatically significant information into focus. So, the paper elaborates the idea of meaning-making in the context-conditioned recurrent semiosis normally accompanied by various pragmatic modifications which have their linguistic, paralinguistic and metatextual indicators.

The reasoning focuses on understanding the results of the reception of one relevant creolized text circulating in modern German-speaking social networks and generated as a reaction of native speakers of the language and members of culture to the current state of affairs. The analysis centers, on the one hand, on reflections on the degree of knowledge significance shared by all members of culture, and, on the other hand, the influence of the characteristics of a single subject’s of personal identity on the result of receiving an axiologically loaded text. A comprehensive multidimensional macrotextual analysis allows us to describe the ratio of verbal and non-verbal means of objectification of information not only about individual subjects whose activities are evaluated in the text both explicitly and implicitly, but also about the “Government” as a collective subject. We also described the methods of activation and co-activation of information about the values included in the worldview. We interpreted the totality of such knowledge as a cognitive background against which information about each of the four persons depicted photographically in the creolized text is profiled. We studied the correlation of information objectified by means of cultural codes, on the one hand, and information which is activated and co-activated in the process of text reception and without which it is impossible to comprehend the text as a whole, on the other hand. We also revealed the mechanisms of verbalizing information, the contribution of which to the coherence of the creolized text turns out to be the most significant. The analysis helps to ascertain conceptual metaphors with the help of which recipients are able to adequately comprehend the content of the creolized text and extract the message of the text. We also analyzed the reasons for the possibility of multiple interpretations of the content of the described text in the same cultural space by subjects with the same collective identity. The results of the macrotextual analysis using well-known generally accepted linguistic techniques are compared with the data of a pilot survey of native speakers of the language within their culture.

Published: December 2024

Human Activity Recognition (HAR) and gender recognition have become pivotal in advancing intelligent systems, as they enable tailored user experiences and enhance automation in healthcare, security, and personalized technology. By accurately identifying human activities and gender, systems can proactively adapt to user needs, improving human-computer interaction, reducing response times in emergency detection, and enhancing the quality of life in smart home and assistive living applications. In this study, a Kolmogorov-Arnold Network model was created to predict daily living activities and the gender of the person performing an activity. The proposed Kolmogorov-Arnold Network (KAN) classifier outperformed the previous studies with 94.5% and 95.6% in terms of overall accuracy for multi-class HAR and gender recognition tasks, respectively. Additionally, the Chi-square test results demonstrated that there is a statistically significant difference between the performances. It can be concluded that KAN method is a robust classifier especially for detecting activities that have a minor number of samples on the utilized dataset.

Pancreatitis is a prominent and severe type of inflammatory disorder with has grabbed a lot of scientific and clinical interest to prevent its onset. It should be detected early to avoid the development of serious complications, which occur due to long term damage. The accurate measurement of biomarkers that are released from the pancreas during inflammation is essential for the detection and early treatment of patients with severe acute and chronic pancreatitis, and this is sub-optimally performed in clinically relevant practices mainly due to the complexity of the procedure and the cost of the treatment. Clinically available tests for early detection of pancreatitis are often time consuming. Early detection of pancreatitis also relates to disorders of the exocrine pancreas, such as cystic fibrosis in the hereditary form and the cystic fibrosis-like syndrome in the acquired form of pancreatitis which are genetic disorders whose symptoms can be correlated to the presence of over expression of specific markers such as creatinine in biological fluids like urine. In this review we have studied how to develop a minimally invasive system using hydrogel-based biosensor, which are highly absorbent and biocompatible polymers which can respond to specific stimuli such as enzymes, pH, temperature, or the presence of biomarkers. These biosensors are helpful for real-time health monitoring, environmental monitoring, and medical diagnostics since they translate biological reactions into quantifiable data. These analytical devices can be used to improve early detection of severe pancreatitis in real time.

Published: December 2024

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive cancer, able to thrive in a challenging tumor microenvironment. Current standard therapies, including surgery, radiation, chemotherapy, and chemoradiation, have shown a dismal survival prognosis, resulting in less than a year of life in the metastatic setting. The pressing need to find better therapeutic methods brought about the discovery of new targeted therapies against the infamous KRAS mutations, the major oncological drivers of PDAC. The most common KRAS mutation is KRASG12D, which causes a conformational change in the protein that constitutively activates downstream signaling pathways driving cancer hallmarks. Novel anti-KRASG12D therapies have been developed for solid-organ tumors, including small compounds, pan-RAS inhibitors, protease inhibitors, chimeric T-cell receptors, and therapeutic vaccines. This comprehensive review summarizes the current knowledge on the biology of KRAS-driven PDAC, the latest therapeutic options that have been experimentally validated, and developments in ongoing clinical trials.

Published: December 2024

This study investigated the physicochemical properties of non-fat yogurt produced with 0.5% fruit seed extracts, including those from date, rosehip, black grape, pomegranate, and grapefruit. The analysis focused on the yogurt samples' pH, titration acidity, total phenolic compound, and antioxidant capacity using various methods (DPPH, ABTS, CUPRAC, and FRAP) and sensory analysis. The results revealed that the functional properties of yogurt could be enhanced by adding fruit seed extracts, with black grape seed extract showing a particularly positive effect on the phenolic components. Moreover, adding date palm seed extract and rosehip seed extract resulted in higher DPPH radical scavenging activity than the other samples. Based on the CUPRAC and FRAP methods, yogurt with date seed extract exhibited the highest antioxidant activity. In contrast, the ABTS method indicated that the yogurt samples containing black grape seed extract and rosehip seed extract exhibited the most significant antioxidant activity. Overall, the antioxidant activity of the yogurt samples with added fruit seed extracts was significantly higher than that of the control sample. Additionally, differences in antioxidant activity among the yogurt samples were observed based on the method used for measurement. This study indicates that yogurt can be developed as a functional product featuring bioactive components, such as antioxidants and phenolics, by enhancing its technological properties by incorporating fruit seed extracts.

Published: December 2024

In this study, the ProCast software incorporating the CAFE model is applied to conduct numerical simulation analysis on the directional solidification process of titanium-aluminum alloy cylindrical rods at varying withdraw rates. According to the analytical results, the withdraw rate is a critical parameter that affects the morphology of the solid-liquid interface and the grain growth behavior during the directional solidification process. An increase in the drawing rate facilitates nucleation undercooling within the rod, inducing a shift in grain morphology from columnar to equiaxed. At a drawing rate of 1 mm/min, the solid-liquid interface exhibits the most stable morphology, as characterized by a flat interface. As indicated by further analysis, at this drawing rate, specific grain orientations are eliminated during competitive growth with an increase in solid fraction, culminating in the formation of columnar grain structures. Additionally, the impact of drawing rate on grain size and number is investigated, with an increase observed in grain number with drawing rate and a decrease found in grain size. The findings of this study contribute to a deeper understanding of mechanisms behind the grain morphology evolution of titanium aluminide, providing crucial support in theory for optimizing directional solidification processes.
