Authors: Pashynskyi Victor , Dzhyrma Stanislav , Pashynskyi Mykola , Nastoiashchyi Vladyslav
Published: January 2025

The constructive-technological decision of the junction design of a block frame window to an uninsulated precast concrete wall which practically excludes a possibility of condensate formation on a surface of internal window jamb is proved. The study was performed by constructing two-dimensional temperature fields in nodes of different designs and comparing the lowest temperature on the internal window jamb surface with the dew point temperature. It is established that thermal reliability can be ensured by the condensate formation criterion by insulating the exterior window jamb with mineral wool or expanded polystyrene slabs and local facade insulation in the form of an outside window casing with 50 mm thickness and 200…250 mm width. The block frame window should be installed at a distance of 60… 80 mm from the outer surface of the precast concrete wall.

Published: January 2025

Currently, there is no single method for determining the width of the cross-section for the elements of anti-landslide retaining structures with a rectangular cross-section (or the diameter of the elements with a round cross-section) at a known distance between them. An algorithm for determining the diameter (in the case of a transitional view of a round shape) or the smaller side (in the case of a transverse transition of a rectangular shape) of anti-vessels supporting structures at a known distance between them is presented. In the course of the above work, obtained analytical dependencies that allow us to determine: the width of the cross-section for the elements of anti-slip retaining structures with a rectangular cross-section (or the diameter of the elements with a round cross-section) at a known distance between them, the step of arranging the elements of anticonvulsant supporting structures with a rectangular cross-sectional shape (or the diameter of the elements of a circular cross-sectional shape) at a known distance between them.

Authors: Dovzhenko Oksana , Pohribnyi Volodymyr , Usenko Valery , Usenko Dmytro
Published: January 2025

Possible causes of destruction of masonry in buildings with bearing masonry walls under the combined effect of vertical and horizontal loads are considered. The diagonal shear is highlighted as a typical case for partitions under seismic impacts. Based on the analysis of the results of experimental studies of samples for skewing, as models of the operation of the partition, proposals are presented for a kinematically possible scheme of the masonry elements destruction, which is proposed as a base for the calculation. The strength problem was solved by the variational method in the theory of plasticity, taking into account both strength characteristics of the masonry, the dimensions of the samples, and the loading areas. The peculiarities of the masonry work are taken into account by using the appropriate strength condition. The influence on the strength of reinforcement of masonry partitions during diagonal splitting is considered.

Published: January 2025

The use of timber structures is gaining popularity around the world. The main laminated timber constructions are beams, the study of which has received much attention. To increase rigidity and strength, beam structures are reinforced. There are many different methods of reinforcing such structures (steel reinforcement, plates, composite reinforcement, etc.). The least researched one of them is reinforcement with composite tapes. For a further detailed analysis of the stress-strain state of laminated timber elements of rectangular cross-section reinforced with composite tapes, a number of numerical researches were performed using the finite element method in the LIRA-CAD software package using three-dimensional and flat finite elements, taking into account the features of work and structure of laminated timber beams and carbon fiber composite tapes. Therefore, according to the conducted research, this method of reinforcement can be considered effective.

Authors: Polituchyi Oleksandr
Published: January 2025

Mathematical models of optimization of rock destruction process during well drilling are considered. In most models, the criterion for optimization is the speed of mechanical drilling. According to the authors, this criterion does not allow optimal use of chisels. A method for determining the energy consumption of the process by measuring technological parameters is proposed. Primary converters of load on the chisel, drilling pressure of the drilling mud and other technological parameters are designed and manufactured. Analog signals are converted into digital. The pulsating signals are smoothed mathematically. The optimization criterion is the minimum value of process energy consumption

Authors: Orysenko Olexandr , Nesterenko Mykola , Shokalo Artem
Published: January 2025

The construction of buildings using 3D printing is becoming increasingly popular. However, this technology, despite its numerous advantages, also has its drawbacks. To minimize the impact of these drawbacks on the quality of construction work, scientifically substantiated approaches can be applied to improve both the technology itself and the machines used in the process. One of the factors that affect the quality of material deposition on the printing surface is the alignment of the extruder's productivity of the construction 3D printer with the speed of its movement above the surface. This can be achieved by considering the physicomechanical properties of the concrete mixture and the method of its delivery to the application area. To describe the mixture's delivery through a narrow channel between the nozzle end of the extruder and the printing surface, the Poiseuille method is proposed, modeling the mixture with the Herschel-Bulkley rheological model. Analytical dependencies have been derived to determine the extruder's productivity and the speed of the mixture extrusion through the nozzle.

Published: January 2025

This article will utilize a weighted regular matrix composed of Fibonacci numbers and variable exponent sequence spaces to create a novel stochastic space with certain geometric and topological properties. This area demonstrates the new form of the Kannan contraction operator with a fixed point. In mathematical economics, we represent economic entities, processes, and phenomena by mathematically structured functional equations, either as summable equations or integral equations. We investigate a category of Volterra-type non-linear dynamical systems, similar to an economic model. We employ our acquired results to formulate new solvability criteria for a unique solution of these non-linear discrete economic dynamical systems. Ultimately, we illustrate our findings with specific instances and applications related to the presence of solutions in non-linear dynamical systems of Volterra-type.
Existence of Solutions to a New Class of Fractional Differential Equations With Antiperiodic Boundary Conditions
Authors: Aljurbua Saleh Fahad , Hammad Hasanen A. , Almutairi Najat Bandar
Published: January 2025

This study introduces a novel class of fractional differential equations characterized by antiperiodic parametric boundary conditions of order µ 2 (2; 3]. The parameters θ and ξ play a crucial role in shaping the boundary conditions by defining specific values and functional behavior. By employing fixed point theorems, we establish existence results for a fractional differential equation equipped with nonlocal antiperiodic boundary conditions involving a Caputo fractional derivative at one of the boundaries. Our investigation centers on a nonlocal point 0 ≤ θ < b, in conjunction with a fixed endpoint at the interval’s extremity (0; b]. This approach enables us to extend the interval of interest to (-1; b]. The findings presented in this study serve to expand and generalize the existing body of knowledge pertaining to nonlocal and classical fractional differential equations.

Authors: Kadhavoor R Karthikeyan , Dharmaraj Mohankumar , Breaz Daniel
Published: January 2025

With primary motive to unify and extend the various well-known studies, we define a new family of differential operator using the $q$-analogue of the generalized $M$-series. The generalized $M$-series unifies two well-known and extensively used special functions namely {\em generalized hypergeometric function} and {\em Mittag-Leffler function}. Making use of the defined operator, we define a new family of analytic functions expressed as a combination two differential characterizations. The combination of differential characterizations involving the operator not only unifies studies of starlike, convex, Bazilevi\v{c} and $\alpha$-convex function classes, it extends to new classes.  Estimates involving the initial coefficients of the functions, which belong to the defined function class are our main results. Some examples along with graphs have been used to establish the inclusion and closure properties.

Published: January 2025

One of the known approaches to studying topological concepts is to utilize subclasses of topology, such as clopen sets and generalized closed sets. In this study, we apply the notion of fuzzy generalized $\mu$-closed sets ($Fg\mu$-closed sets) to establish and analyze novel categories of spaces, namely $Fg\mu $-regular, $Fg\mu $-normal, and $F\mu $-symmetric spaces in the frame of generalized fuzzy topology($GFT$). We investigate the fundamental properties of these classes, exploring their unique characteristics and preservation theorems under $Fg\mu$-continuous maps. We establish the interrelationships between these classes and the other separation axioms in this setting, and we demonstrated that $F\mu $-regular, $F\mu $-normal, and $F\mu $-symmetric spaces are special cases of $Fg\mu $-regular, $Fg\mu $-normal, and $F\mu$-$T_{1}$ spaces respectively. Additionally, we show that the equivalence for these cases hold when the $GFT$ is $F\mu$-$T_{\frac{1}{2}}$. The connections between these classes and their counterparts in the crisp $GT$ are studied. Finally, we discuss these classes' hereditary and topological properties, further enhancing our comprehension of their behavior and implications.

Authors: González Cordero Francisco Javier , Salguero Velázquez María Alejandra
Published: January 2025

El objetivo de este trabajo es analizar las líneas de investigación existentes en torno a los hombres envejecidos, identificando cuatro vertientes de análisis: 1) cambios en la vida tras el fin o la reducción de la vida laboral; 2) las transformaciones corporales asociadas al proceso de envejecimiento, así como los cambios en la salud; 3) las relaciones familiares y la participación en redes de apoyo; y 4) la participación en actividades comunitarias. Para el análisis se emplean los aportes teóricos de los estudios sobre masculinidades, así como el enfoque de curso de vida para examinar los cambios a lo largo de la vida y el impacto de las transformaciones sociohistóricas del siglo XX que institucionalizaron al trabajo asalariado como eje principal de la existencia de los hombres.

A lo largo de la revisión, se observan los malestares que los varones presentan al no cumplir con los mandatos de género asociados al trabajo, así como la fuerza y resistencia física. Sin embargo, estos elementos no son permanentes ni determinan su vejez. Por el contrario, se identifica la resignificación de las identidades de género, incorporando elementos relacionados con el cuidado, el acompañamiento y la participación colectiva.

POSTMODERN THEATRE AND RESISTANCE: A CATALYST FOR TRANSFORMATIVE EXPRESSION
Authors: Krishnan Vineetha
Published: January 2025

Postmodern feminist theatre in India redefines storytelling by integrating fragmented narratives, cultural hybridity, and active audience engagement to critique societal power structures. It amplifies marginalized voices through mythological reinterpretations, experimental performances, and community-driven initiatives. Themes of gender, caste, class, and identity intersect, fostering dialogue and activism. Embracing innovation, ecofeminism, and intersectionality, this dynamic genre continues to challenge patriarchy, inspire social change, and create inclusive spaces for resistance, dialogue, and empowerment. Unlike traditional theatre, which often relies on realism and imitating life (mimesis), postmodern theatre rejects these conventions, opting for abstract, fragmented, and non-linear narratives instead. This departure from the norm allows the medium to construct unique and thought-provoking representations that serve as powerful tools for social critique. In essence, postmodern theatre acts as a living canvas for resistance, fostering an environment where art, activism, and community intersect. It challenges traditional forms while offering an inclusive platform for exploring diverse perspectives, ultimately contributing to transformative social change. Indian postmodern theatre serves as a powerful platform for feminist expression, bringing to light themes that challenge patriarchal constructs and amplify marginalised voices. These themes, rooted in the complexities of identity, culture, and resistance, redefine the role of theatre as a medium for socio-political critique and transformation.

Published: January 2025

Neuroendocrine carcinoma of the esophagus is a rare, highly aggressive malignancy characterized by rapid progression. The clinical picture is not very specific, ranging from simple abdominal discomfort to dysphagia with altered general condition.

Here, we present the case of a 65-year-old woman with a history of chronic gastroesophageal reflux disease, who presented with dysphagia, exploration of which revealed neuroendocrine carcinoma of the esophagus.

Due to its rarity, the treatment strategy is not yet standardized. Surgery combined with adjuvant therapy appears to be the best option for treating limited-stage esophageal neuroendocrine carcinoma.

Authors: Chitoor Venkat Rao Ajay Kumar  , Shanti Lekhana Yakkaladevi  , Samagna Pandiri  , Yeshwanth Godugu
Published: January 2025

Phishing attacks are a persistent cybersecurity threat, exploiting human vulnerabilities via deceptive emails and malicious URLs. This project introduces a novel Reinforcement Learning (RL)-based system to automate phishing detection and response. By employing advanced RL algorithms, such as Deep Q-Learning and Policy Gradient methods, the system dynamically learns to identify phishing indicators within email content and URLs through Natural Language Processing (NLP) and feature extraction techniques. The RL agent continuously adapts its detection strategies based on evolving threats and user feedback, aiming to minimize false positives while accurately identifying malicious activities. Upon detecting potential threats, the system initiates automated responses, including alert notifications, URL blocking, and user warnings, thereby enhancing security measures. Implementing this RL-based solution within Security Operations Centers (SOCs) or email security platforms offers a scalable, real-time defense against phishing attacks. This approach effectively safeguards sensitive information and strengthens organizational resilience against cyber threats.
Data Privacy and Security in AI: Strategies for protecting user data while maintaining the functionality and scalability of AI solutions
Authors: Sameerkumar Babubhai Prajapati
Published: January 2025

AI continues to grow fast and the integration across several industries has changed the manner of doing business and delivering services. But such trend has put important questions on data protection. A significant number of AI systems depend on large datasets that contain client and often private data to provide intelligent and efficient results. One disadvantage of using this data dependency is the vulnerability that AI systems have to privacy infringement, hacking, and illegal access, which are detrimental on both, the side of user trust and the system. This paper discusses the main issues that arise concerning data privacy and security in Artificial Intelligence and provides an extensive analysis of potential approaches to preserving users’ information while keeping AI systems’ performance and adaptability. It discusses specific well-known approaches for the preservation of privacy including differential privacy, Federated learning,

Homomorphic encryption, and Secure Multi-Party computation (SMPC). They are meant to protect personal data to allow AI models to make predictions or analysis. The paper also solves an essential, inevitable problem of reconciling protection of privacy with necessity of massive data handling. To protect privacy, approaches and mechanisms are applied and designed to provide great security to data; however, they make the computation slow and sometimes impact the quality of AI models. Also, the paper covers recommendations concerning the design of AI solutions that will remain secure and scalable with reference to security and personalization issues and performance rates. The insights derived from the findings will prove useful to the research community, developers, and policymakers to draw a road map for regulate AI and data protection in the emerging technological environments

Published: January 2025

One of the most worrisome environmental challenges facing the globe today is the issue associated with the impacts of climate change most especially on the urban environment. The variations in climatic condition of cities in developing world today as experienced over time cannot be overemphasized. This study investigated the spatio-temporal variations of climate change and urban heat island, taking into cognizance its implications on physical planning in Port Harcourt Rivers State. The study adopted the qualitative design approach and data were obtained from secondary sources. Remotely sensed data from USGS Earth Explorer and Landsat OLI/TIRS data for 2015 and 2024 with minimal cloud cover were obtained. A comparative analysis using ArcGIS was carried out to show spatial patterns and Land Surface Temperature change in the study area. The Land Surface Temperature change was calculated using TOA, BT, emitted radiance wavelength, and Land Surface Emission with an extension in ArcGIS software. The Land Surface Temperature analysis in 2015 and 2024 revealed a significant increase in temperature. Impervious surface analysis using NDVI indicated a rise in built-up areas over the years. The relationship between impervious surface and Land Surface Temperature highlighted the impact of urbanization on temperature changes. The study therefore recommended strategies like increasing urban greenery, using cool roofs and pavements, urban planning and design improvements, energy efficiency measures, urban regeneration and watershed management as preventive and mitigative measures.

Data has become a cornerstone in transforming public health interventions, driving the shift towards evidence-based decision-making that ensures impactful and sustainable health outcomes. This manuscript explores the pivotal role of data in designing, implementing, and evaluating public health programs, emphasizing how robust evidence informs strategies to address pressing health challenges. With growing complexities in global health systems and disparities in resource allocation, leveraging data-driven insights has emerged as a vital approach to optimizing interventions, particularly in underserved and resource-limited populations. The manuscript begins by discussing the foundational importance of comprehensive data collection systems, highlighting the need for accuracy, consistency, and inclusivity in capturing diverse health metrics. It then examines the integration of innovative analytical methods, including machine learning and predictive analytics, to uncover trends, identify risk factors, and anticipate emerging health threats. Real-world examples illustrate how data transforms interventions, from enhancing disease surveillance to tailoring community-specific health initiatives. The application of evidence-based findings to public health decision-making is further explored, demonstrating how data empowers stakeholders to allocate resources efficiently, prioritize vulnerable populations, and evaluate program effectiveness. The manuscript also addresses challenges such as data privacy, infrastructure gaps, and disparities in access to analytical tools, offering actionable solutions to overcome these barriers. By aligning technological advancements with evidence-based approaches, this manuscript underscores the transformative potential of data in public health, paving the way for adaptive, equitable, and impactful interventions.

Objective. To review the literature data on the comorbidity of cardiovascular disease with Parkinson’s disease (PD) and to evaluate the role of cardiovascular autonomic failure as a differential diagnostic criterion for synucleinopathy. Material and methods. The search of scientific literature was performed in PubMed, ProQuest Dissertations & Theses Global databases, electronic library system of the Media Sphere publishing house from 2014 to the present and includes 42 relevant sources. The methodological premise of the study is the notion of the differentiating role of autonomic dysfunction symptoms in the diagnosis of PD at the premotor stage. Conclusion. Autonomic cardiac denervation occurs at the premotor stage of PD and may be its primary manifestations. Patients with PD also develop other comorbid cardiovascular pathology: ischaemic heart disease, arrhythmias, cardiomyopathies and sudden cardiac death. Nosological substantiation of cardiovascular autonomic failure is crucial for providing specialised cardiological care to PD patients.

Most patients with chronic migraine (CM) have musculoskeletal neck pain, which maintains the chronic course of migraine and complicates treatment. Cognitive behavioral therapy (CBT) is promising in the complex treatment of patients with CM and cervicalgia. However, few randomized trials have been conducted to evaluate the effectiveness of CBT in CM.The aim of the study was to evaluate the effectiveness of an multidisciplinary program including CBT in the treatment of patients with CM and neck pain.Material and methods. The study included 120 patients with CM and neck pain (41 men and 79 women), average age 35.7 ± 9.2 years. All patients underwent a clinical interview, neurological examination and testing using clinical and psychological methods. Patients were randomized into two groups: group 1 received standard treatment and CBT, group 2 — only standard treatment. All patients were assessed for clinical and psychological indicators before treatment and at 3, 6, 12 and 24 months follow-up.Results. At 3 months follow-up, statistically significant (p < 0.05) improvement was observed in group 1: decrease in headache frequency, frequency and doses of taking painkillers (PK), neck pain intensity by the Visual Analogue Scale (VAS), the Total pericranial pain score, in the Migraine Disability Assessment (MIDAS), in the Neck Disability Index (NDI), in the Pain catastrophizing scale, the State-Trait Anxiety Inventory, the Center for Epidemiologic Studies Depression Scale. At 6, 12 and 24 months follow-up, the achieved improvements were maintained. In group 2, at 3 months follow-up, statistically significant improvement was observed in only six indicators — headache frequency, frequency and doses of taking PK, neck pain intensity by VAS, MIDAS and NDI. However, at 6, 12 and 24 months of follow-up the achieved improvements were not maintained in group 2. At 3 months of follow-upin group 1 was clinical efficacy (CE) for CM (decrease in headache frequency by 50% or more) and CE for neck pain (decrease in pain intensity by VAS and the NDI by 30% or more) achieved by 75% of patients, in group 2 — 45% (p < 0.001). At 24 months follow-up in group 1 CE for CM and neck pain was achieved by 80% of patients, in group 2 — 30%.Conclusion. An multidisciplinary program including CBT is significantly more effective than standard treatment for chronic migraine and neck in the short and long term.
Catastrophic lava flow levee failure: precursors, processes, and implications

During an effusive eruption crisis the initial advance of a lava flow is typically the primary focus of model forecasts and hazard management efforts. Flow branching and lateral expansion of lava flows can pose significant dangers within evolving flow fields throughout the duration of an eruption and are an underappreciated hazard. We use field monitoring, infrasound, time lapse imagery, and lidar data collected during the 2018 lower East Rift Zone eruption of Kīlauea (Hawai‘i) to track the origins, progression, and implications of a flow branching event caused by catastrophic levee failure. Our analyses show that surges in effusion rate, rheologic transitions between pāhoehoe and ‘a‘ā flow regimes, slope-breaks, pre-existing topographic highs, and the structure of perched levee walls all played a role in the failure of the levee and subsequent re-routing of the lava flow. Failure of perched lava structures leads to an acutely hazardous situation because lava impounded by the structure can rapidly inundate the landscape. This is the first time a levee failure event has been observed in such detail with numerous monitoring techniques; this unprecedented level of observation provides quantifiable insights into levee failure processes that have important implications for hazard mitigation and an improved understanding of lava flow emplacement dynamics
