Authors:   State University of Information and Communication Technologies, Kyiv, Vyshnivskyi O. V.
Published: January 2024

The article is devoted to critical aspects during the implementation of Web-3.0 technology. The task is set: based on the analysis of the implementation of Web-3.0 technology to solve a number of tasks, namely: blockchain-based decentralization; creation of general accessibility; increasing trust in sites; increasing the security of personal information from hackers; ensuring true ownership of authors' information; lack of censorship; improvement of social interaction; use of the Internet of Things is compatible with virtual or augmented reality; application of artificial intelligence – consider a zero-day exploit for Web-3.0. A zero-day exploit indicates that the vendor or developer has just become aware of the vulnerability and has "zero days" to fix it. A zero-day attack occurs as a result of attackers exploiting a vulnerability (critical points) before the developers managed to fix it. To solve this problem in the article: a description of the main differences between the Web-3.0 construction architecture and Web-2.0 is made; the analysis of the tasks of Oprah Winfrey Network of the Web-3.0 architecture was carried out; consider the possibilities of: external interface (design and interface of web applications), server part (based on decentralized technologies, primarily dApp, which uses the advantages of blockchain: transparency, reliability and immutability of data.), database (stores data about users, their messages , tags and comments); an analysis of possible threats and vulnerabilities due to the introduction of Web-3.0 technology before the start of the zero-day exploit was performed. Based on the performed analysis, the following conclusions are drawn: that the vulnerability is related to scalability, limited transaction throughput and computing power, security, complexity, compatibility; that Web-3.0 creates many conditions that can be useful to people, but the introduction of new Web-3.0 capabilities leads to the emergence of new threats or vulnerabilities that can be used by attackers to harm people. This requires considering the possible impact of threats, identifying possible vulnerabilities in Web-3.0 technology before the start of a zero-day exploit, that is, it requires the need to investigate the possibility of the appearance of new vulnerabilities.

Improving stock price forecasting based on recurrent neural networks
Authors:   State University of Information and Communication Technologies, Kyiv, Shcherbyna I. S.
Published: January 2024

The article is devoted to the study of the application of machine learning for forecasting the stock price in the stock markets in the context of the growing capabilities of artificial intelligence. The article examines the issues and relevance of stock price forecasting, as well as describes current approaches to such forecasting as fundamental and technical analysis. Within technical analysis, widely used methods and algorithms of statistics, pattern recognition, sentiment analysis and machine learning are considered. The article focuses on the advantages of using recurrent neural networks as one of the types of artificial neural networks that work with sequential data or time series. Traditional neural networks treat data inputs and outputs as independent of each other, while recurrent neural networks take into account previous elements in the sequence to generate the output, which allows for better prediction of price trends. The article describes the main architectures of recurrent neural networks that exist at the moment and their features, including bidirectional recurrent neural networks, closed recurrent block, and long short-term memory. The last architecture - long short-term memory - was considered in the most detail. This architecture is one of the most difficult to learn and configure, at the same time, it is the most effective for complex tasks such as forecasting the dynamic course of shares. One of its key advantages is solving the problem of gradient damping, that is, the ability to store the context within which price data is analyzed, which makes it possible to detect long-term historical trends and predict future values with high accuracy.
Adaptive method and algorithm for the operational estimation of traffic parameters in high-speed corporate multiservice communication networks
Authors:   State University of Information and Communication Technologies, Kyiv, Trenova K. O.
Published: January 2024

The article develops an adaptive method and an algorithm for operational evaluation of traffic characteristics and parameters in high-speed corporate multi-service communication networks, which implements it. This algorithm works in real time. High-speed corporate multi-service networks are characterized by high dynamics of changes in their state, including changes in the characteristics of transmitted traffic. Under these conditions, the automated network management system must ensure the required quality of services and communication services provided to users. The relevance of this study is determined by the need to implement network management processes in a mode close to real time, with a given quality in conditions of dynamic, unknown changes in network characteristics. The basis of the proposed method is the concept of conditional nonlinear Pareto-optimal filtering, which consists in the fact that the estimation of traffic parameters takes place in two stages: at the beginning, the forecast of parameter values is estimated, and then, with the receipt of subsequent parameter observations, their adjustment takes place. The proposed method and algorithm belong to the class of methods and algorithms with prior training. The average relative error of the estimation of traffic parameters does not exceed 7%, which is a sufficient value for the implementation of operational network management tasks.

Published: January 2024

Although there are studies on the effect of alexithymia on expressed emotion, emotion expression in people with alexithymia was not specifically examined. This study aimed to investigate the relationship between alexithymia and emotional expression styles and whether emotional intelligence and empathy mediate this relationship. A total of 254 teacher candidates were evaluated using the Toronto Alexithymia Scale, Empathy Quotient Scale, Trait Emotional Intelligence Questionnaire, and Emotional Expression Styles Inventory. We performed the analyses using structural equation models. Our results revealed that alexithymia indirectly affected the expression style of happiness and sadness emotions negatively and emotional intelligence and empathy played a mediator role in this effect of alexithymia. Also, an indirect positive relationship was identified between alexithymia and anger expression style, and it was found that this relationship was mediated by emotional intelligence. Accordingly, emotional expression styles were also related to other variables. The present study also determined that alexithymia level was significantly and negatively correlated with emotional intelligence and empathy levels. This is the first study to reveal that alexithymia is related to emotional expression styles and that emotional intelligence and empathy also have mediator roles in emotional expression styles. expression styles were also related to other variables.

Published: January 2024

Psychische mishandeling komt vaak voor en kan diepe sporen achterlaten. Het is een vrijwel onzichtbare, subtiel verhulde vorm van mishandeling, die zich niet snel laat duiden. Het is een relatief onbekende vorm van mishandeling, zowel cliënten zelf als professionals herkennen het vaak niet. Ook maatschappelijk is er nog een gebrek aan kennis en (h)erkenning. Des te meer reden om hier aandacht aan te geven. Ik beschrijf aan de hand van de casus van Martha wat de impact van psychische mishandeling is op iemands leven en welke uitgangspunten en stappen er nodig zijn in de behandeling. Kennis van relationeel trauma en de specifieke dynamiek van psychische mishandeling is cruciaal voor effectieve behandeling. Naast psycho-educatie voor de cliënt, zijn vier bestandsdelen kenmerkend voor de effectieve behandeling van de gevolgen van psychische mishandeling: doorvragen op de relatie, ontschuldiging, morele stellingname en het aanbrengen van de realiteit.

Published: January 2024

Forest plantings have a positive impact on soils, at the same time, the issues related to the role of shrub belts in the reclamation activities are poorly studied. There is a need to investigate their impact, especially in relation to saline soils. Today, tree plantations are more preferable than shrubs within the framework of steppe afforestation carried out in the arid zone. The purpose of the present study is to determine the reclamation efficiency of field-protective forest plantations, consisting of both tree stands and shrub belts, on solonetz soils. The research was conducted from 2020 to 2022 on the experimental plot laid in 1989-1991 in Kotelnikovsky district of Volgograd region. The experiments were conducted with the use of general research methods applied in agroforestry on a site area of 651.3 hectares. Soil sites were laid out according to the developed and standard methodology. From this study, a detailed evaluation of the forest conditions of the experimental site was determined. In general, they are unfavorable for growing protective forest plantations. The soils are saline to a different extent, the reserves of productive moisture are extremely limited, the positive and negative temperatures are extreme, and the relative air humidity is low. The reclamation efficiency of forest belts with inclusions of shrub belts on solonetz soils shows a positive impact of the shrub phytomass on the agroecology of arable land.

Published: January 2024

Despite being historically renowned as a significant date producer, both the Arab world and Iraq have experienced a noticeable decline in date palm production in recent years. This decrease in output can be attributed to the sluggish integration of advanced techniques that could enhance and maintain high-quality yields. In this regard, an experiment was conducted at the Al-Rabee station on date palm cultivar Khastawi under the randomized complete blocks design with three replications, to study the effect of four treatments of bagging: B0 - Without bagging, B1 - Rocklin, B2- Agryl and B3 - Paper bags and four bagging periods: T0 – 0, T1 - 40, T2 – 50 and T3 - 60 days, and their interactions on the fruits characteristics of date palm cv. Khastawi. The results showed that T1B3 treatment gave the highest values in fruit set (86.55%), while T3B2 treatment was superior in respect to fruit weight (7.260g), seed weight (0.6300g), fresh weight (6.630g) and fruit diameter (1.8533cm). The lowest values of fruit characteristics were recorded in the control treatment. Therefore, we recommend using bagging fruits to improve fruit set, bunch yield and fruit quality.

In locally advanced breast cancer, neoadjuvant treatment has led to significant successes, which are of particular importance in the HER2-positive and triple-negative subtypes. However, its role in the treatment of luminal HER2-negative ER+/HER2-breast cancer is still under debate, due to low morphological complete response rates and limited significance of this factor as a predictor of long-term outcomes. At the same time, the administration of neoadjuvant chemotherapy to patients with locally advanced ER+/HER2-cancer is widely used in clinical practice. Neoadjuvant hormone therapy still holds untapped potential in the treatment of this subgroup of patients, especially in elderly and comorbid patients. In this paper, we present the results of neoadjuvant use of tamoxifen and/or aromatase inhibitors, as well as CDK4/6 and PI3K/mTOR inhibitors. We also discuss issues related to the optimal duration of treatment and show a comparison of the efficacy of neoadjuvant hormonal therapy and chemotherapy in different patient groups.
Politik im Zeitnotstand
Authors: Rinderspacher Jürgen P.
Published: January 2024

Zeitdruck ist zur zentralen Herausforderung für politisches Handeln geworden. Katastrophen, Krisen, Kriege und der große Transformationsprozess hin zur Klimaneutralität überlagern sich und gewähren wenig Spielraum für Kommunikation und demokratische Prozesse. Freiheit, Wohlstand und nicht zuletzt das Recht auf eigene Zeit scheinen durch die Gegenmaßnahmen der politisch Verantwortlichen immer öfter in Frage gestellt. Wenn allerdings nicht rechtzeitig gehandelt wird, sind diese Güter ebenfalls bedroht. Gibt es Wege, die aus diesem Rechtzeitigkeits-Dilemma herausführen?
CRACK INITIATION AT GRAIN BOUNDARY WITH A VARIABLE MISORIENTATION VECTOR
Authors: Perevezentsev V.N. , Kirikov S.V.
Published: January 2024

A model is proposed for the initiation of cracks at “knife” grain boundaries, i.e., rectilinear, broken boundaries of deformation origin, oriented along the tension axis, arising as a result of rotational incompatibility in the form of a disclination dump at the stage of pre-fracture of the material. The disorientation of the “knife” boundary decreases down to the breaking point in the body of the grain, and its decrease (rotational instability damping) occurs not continuously, but discretely through the branching of secondary low- and high-angle boundaries. In this case, along the “knife” boundary, at the points of its branching, linear mesodefects of the rotational type arise-wedge disclinations of the same sign. A model of crack initiation in an elastic field of a chain of negative disclinations that create tensile elastic stresses is proposed. When analyzing the conditions for crack initiation, a combined criterion was used, according to which the simultaneous fulfillment of force and energy conditions was required for crack initiation. Within the framework of this model, the critical values of the total value of the Frank vector of disclinations located on the “knife” boundary and the average gradient of its misorientation are calculated, upon reaching which the criterion of crack initiation is satisfied. The dependences of these quantities on the length of the “knife” boundary and the effective screening radius of the elastic field of disclinations are calculated. It is shown that the appearance of cracks is most likely at the boundaries with the largest misorientation gradient (exceeding 8–20 deg/?m, depending on the length of the boundary).
EXPERIMENTAL SETUP FOR DYNAMIC LOADING TIME-CONTROLLED
Authors: Makarov N.S.
Published: January 2024

The occurrence and development of damage in concrete and other brittle materials subjected to mechanical loads of varying intensity and duration, at the macroscopic level manifests itself in the form of cracking and fragmentation and makes a significant contribution to the load-bearing capacity of structures. To quantify the strength degradation of the damaged material, a scalar damage parameter is often used. Experimental investigation of the damage accumulation process under high-speed dynamic loads requires a tool that allows stopping the deformation process of a specimen at a given strain rate at a given strain magnitude. The proposed work is devoted to the problem of experimental study of damage accumulation process in brittle materials. Some common models used to predict the processes of dynamic deformation and fracture of concrete taking into account damage under loading are described. An experimental setup realizing a modification of the Kola method is developed to obtain the specified degrees of deformation of the specimen at different strain rates. Several load shaping schemes are considered. Two schemes allow limiting the deformation of the specimen in the experiment by adjusting the duration of the loading pulse, and one scheme allows limiting the deformation of the specimen due to the presence of a rigid ring surrounding the specimen. The processes of load formation and dynamic deformation of the specimen under the action of this load were analyzed using the following methods.
The Effectiveness of Prison Education in Reducing Criminal Recidivism: A Systematic Review
Authors: Castell-Britton Sigifredo
Published: January 2024

Criminology defines recidivism as the relapse into criminal behavior of individuals with a criminal record. Prisoners are a vulnerable sector of the population which makes reintegration programs vital to facilitate their reinsertion into society after liberation. This study conducts a systematic review of the literature on prison education and recidivism in the last 5 years. PICO eligibility criteria were applied, various sources were used, and 10 studies were selected for the review. The studies address recidivism through qualitative, quantitative, and mixed approaches, revealing the complexity of the issue and the need for comprehensive and tailored approaches. Concerns arise about the ineffectiveness of criminal policies and the need for reforms in prison conditions and education. Studies suggest a weak relationship between participation in educational programs and recidivism prevention, emphasizing the importance of a humanistic and more holistic approach to rehabilitation. Factors such as low enrollment in the programs, overcrowding in prisons, lack of access to post-secondary education influence program effectiveness. The importance of preventive policies, removal of obstacles to reentry, social integration programs, and adapting interventions to specific population needs is emphasized. Findings highlight the urgency of addressing structural issues and the importance of a holistic approach to prison system reform. Lack of resources and adequate support often hinders rehabilitation efforts. Implementing comprehensive preventive and corrective measures is essential to improve outcomes and reduce recidivism.

Global Realism with Bipolar Strings — From Bell Test to Real-World Causal-Logical Quantum Gravity and Brain-Universe Similarity for Entangled Machine Thinking and Imagination
Authors: Zhang Wen-Ran
Published: January 2024

Following Einstein’s prediction that _“physics constitutes a logical system of thought”_and_“nature is the realization of the simplest conceivable mathematical ideas” _this topical review outlines a formal extension of _local realism_ limited by the speed of light to _global realism with bipolar strings (GRBS)_ that unifies the principle of locality with quantum nonlocality. Related literatures are critically reviewed to justify GRBS which is shown a necessary and inevitable consequence of Bell test and an equilibrium-based axiomatization of physics and quantum information science for brain-universe similarityand human-level intelligence. With logically definable causality in regularity for quantum superposition and entanglement, GRBS makes spacetime emergence and submergence ubiquitous in both the physical and mental worlds—an unexpected but long-sought simplification of quantum gravity with brain-universe similarity and complete background independence. It is shown that GRBS forms a basis for _quantum intelligence (QI)_—a spacetime transcendent, quantum-digital compatible, analytical quantum computing paradigm where bipolar strings lead to _bipolar entropy_ for energy/information conservation, regeneration, and degeneration toward _quantum cognition and quantum biology (QCQB)_ as well as information-conservational blackhole keypad compression and big bang data recovery. Thus, GRBS is justified as a _real-world quantum gravity (RWQG) _theory—a bipolar relativistic causal-logical reconceptualization and unification of string theory, loop quantum gravity, and M-theory—the three roads to quantum gravity. Based on GRBS it is posited: (1) life is a living bipolar superstring regulated by _bipolar entropy_ that unifies order and disorder; (2) thinking or consciousness as a prerequisite for human-level intelligence is fundamentally mind-light-matter unitary QI logically equivalent to quantum emergence (entanglement) and submergence (collapse) of spacetime. The two posits lead to a positive answer to the question _“If AI machine cannot think, can QI machine think?” _Causal-logical brain modeling for _entangled machine thinking and imagination (EMTI)_ is proposed and graphically illustrated. Testability and falsifiability of GRBS is discussed.
