Authors: Castro Zapata Edgar Iván , Londoño Bonilla Pamela
Published: January 2025

El presente artículo, tiene como objetivo reflexionar frente al uso del conocimiento, la tecnología, el capital humano y la enseñanza del inglés como mecanismos de control social determinantes del proceder humano, los cuales, se considera que emergen de estándares mercantilistas que en la era globalizada adquieren mayor proscenio en contextos como el académico, el laboral, el social, el científico, el cotidiano, entre otros. Subsecuentemente, se plantea una investigación cualitativa de análisis documental de diversas fuentes bibliográficas relacionadas con las temáticas previamente mencionadas. En consecuencia, como propuesta, se rescata la pedagogía crítica como dispositivo de emancipación frente a sistemas hegemónicos de manipulación y condicionamiento del comportamiento social. Finalmente, se concluye que la educación como sistema de formación del ser favorece la lucha por el rescate de lo humano en el contexto neocapitalista, puesto que, puede brindar espacios críticos que favorezcan la inmersión en el mundo desde una visión activa, propositiva y transformadora de la realidad.

Authors:   University at Albany, Albany, NY, United States, Shah Samarth , Liang Xiangbo ,   New York University, New York, NY, United States
Published: January 2025

The shift-left paradigm lays focus on preventing the existence of vulnerabilities due to integration of
security solutions with the software development life cycle (SDLC). This study investigates how shift-left vulnerability
scanning methods can be applied to integrate container security analysis into CI/CD processes. By embedding security
practices, such as Static Application Security Testing (SAST), Dynamic Application Security Testing (DAST), and
Software Composition Analysis (SCA), into the CI/CD process, organizations can detect and mitigate vulnerabilities
during code development, build, testing, and deployment stages. Trivia, Anchore and Snyk presented tools for
container vulnerability scanning, and this gives a detailed description of advanced security, as well as compliance
usage. Areas of concern having to do with performance, trade-offs, integration and developers are also considered. The
results highlight a high degree of importance of timely detection, regular examination, and the necessity to embrace the
integrated model between Development and Security teams to feature a highly efficient and secure DevOps system.
Leaf Blade Anatomy of Homolepis (Poaceae) Species as Contribution to the Genus Taxonomy
Authors: Severino Francivaldo Sousa , de Oliveira Regina Célia , Gomes Sueli Maria
Published: January 2025

Abstract— Homolepis (Paspaleae, Arthropogoninae) is a monophyletic genus consisting of five species distributed from Central America to Argentina. The purpose of this work is to test the taxonomic value of leaf histological characters for this genus, including
the vascular formula. Cross sections and paradermal preparations were obtained and analyzed. The present study expanded the number of species anatomically described and the number of descriptors used for their characterization. The species of Homolepis were anatomically distinguished
among them. An identification key was presented based exclusively on leaf blade anatomy, with illustrations for all species. Anatomical characters useful for the taxonomy were central bulliform cell height versus width relation, as well as their thickness in relation to the leaf blade, presence
of fusoid cells, mesophyll classification, relative height of the adaxial chlorenchyma cells*, and presence of interfascicular high cells*. Regarding the midvein, the significant features were the presence of axillary bulliform cells, of collenchyma, of radiate chlorenchyma, of adaxial auxiliary
vascular bundle*, and of medulla, as well as the relative height of its colorless cells*. The features with asterisks were used here for the first time for Poaceae. The presence of third order bundles restricted to the leaf margin and the vascular formula were useful to distinguish Homolepis
from other Poaceae genera, such as Mesosetum and Paspalum, although these same features were poor at discriminating among Homolepis species. Leaf anatomical similarities group H. aturensis with H. isocalycia, as well as H. glutinosa with H. villaricensis,
while H. longispicula is distinguished from the remaining species of the genus. The data can be useful for the elaboration of a phylogenetic proposal with morphological markers for the Homolepis species.Keywords—Gramineae, Kranz anatomy, macrohairs, Paniceae,

The Genus Abutilon (Malvaceae: Malvoideae) in India: A Taxonomic Revision and Insights from Micromorphology of Seeds
Authors: Nimbalkar Varsha Vilasrao , Sardesai Milind Madhav
Published: January 2025

Abstract— This paper presents a taxonomic revision of the genus Abutilon in India, supported by detailed seed morphology. Twelve species and two varieties are recognized from India and each described with their synonymy, nomenclature notes, illustrations, habitat
specificity, geographical distribution, phenology, and specimens observed in various herbaria across India. A comprehensive key is provided for the identification of species and varieties. Lectotypes are designated for nine names including a second-step lectotype for A. fruticosum.
Infraspecific taxa are reevaluated, resulting in the synonymization of A. bidentatum var. major, A. fruticosum var. chrysocarpa, and A. hirtum var. heterotrichum with their respective species. A. indicum subsp. guineense
is reinstated as distinct species and A. pakistanicum is determined to be an excluded species. Throughout the study, seed micro-morphology is identified as a crucial tool for discriminating taxa at the interspecific and infraspecific levels. The previously proposed infraspecific
classification of A. indicum is invalidated in this study which is corroborated by morphology and distribution of the taxa. This study provides the first comprehensive taxonomic account of the genus Abutilon in India with discussion on fruit dehiscence.

Published: January 2025

Abstract—In the 21st century, innovation and entrepreneurship are major forces behind social advancement, economic expansion, and environmental sustainability. Problem Based Learning (PBL), is a type of student-centered learning where learning occurs in a context-specific manner, students actively participate in the process and they accomplish their objectives through social interactions. The purpose of this study is to investigate how entrepreneurship and innovation education in a course developed under the PBL model might foster the entrepreneurial spirit in engineering students. The students were required to work in groups and finish tasks that took the shape of challenges in order to represent actual issues that an entrepreneur would face. Multiple assessment patterns such as class activity participation, case study analysis, Ideathon or Hackathon participation, business model canvas and value proposition canvas presentation, pitch deck participation, company formation, patent filing, funding proposal submission were part of the course evaluation. Evaluation rubrics were framed for each assessment pattern planned in this study to grade the students. The entire student groups completed case study analysis, participated in ideathon and hackathon, designed their business model canvas and formulated a business plan based on their product which was presented in the pitch deck. The quantitative survey feedback and qualitative testimonies received from students, point to PBL's prospective strengths and its ability to help people become better entrepreneurs. The results make it abundantly evident that the exercises created for this study can be repeated in any interdisciplinary classroom setting. Keywords—Innovation, Entrepreneurship, PBL, Engineering.

Abstract— The transition from Lecture-Based Learning (LBL) to Problem Based Learning (PBL) represents a significant shift in Educational systems. Traditional LBL doesn’t have student centric approach but however, with the growing limitations in this approach educators are moving toward PBL to enable active learning, critical thinking and real world problemsolving skills. While the benefits of PBL are widely acknowledged, the challenges of implementing this pedagogical shift, particularly in terms of student acceptance and teacher adaptation, remain significant areas of concern. This paper presents the challenges and benefits of the transformation in education from LBL to PBL. The paper focuses on understanding the factors influencing student acceptance of PBL and the struggles faced by educators in implementing this innovative teaching approach. By exploring these dynamics, the study seeks to provide insights into effective strategies for facilitating the successful adoption of PBL in diverse educational contexts. The study employs a mixed-methods approach, combining quantitative surveys with qualitative interviews and observations. Initially, baseline data is collected to assess student attitudes and perceptions towards traditional lecture-based learning and their readiness for PBL. Subsequently, a carefully designed PBL curriculum is implemented, incorporating feedback from stakeholders and best practices in PBL pedagogy. Throughout the implementation process, data is collected on student engagement, learning outcomes, and teacher experiences. Successful implementation of PBL requires Student readiness, teacher training and Curriculum alignment. By addressing these factors proactively, educational institutions can maximize the benefits of PBL and create enriching learning experiences for students.

On the Thermalization of One-Dimensional lattices. II. Canonical Ensemble
Authors: Vinogradov G.A. , Lakhno V.D.
Published: January 2025

In this paper we consider the thermalization of one-dimensional lattices in the canonical ensemble. The main methods of thermalizationare described, including the Nose–Hoover algorithm and the stochastic Langevin method. The thermalization of lattices with "rigid" symmetric potential β–Fermi–Pasta–Ulam–Tsingou is considered in detail. This example demonstrates the quantitative and qualitative characteristics of the thermalization process. In the next section, the thermalization of a lattice with a "soft'' asymmetric Peyrard–Bishop–Holstein potential is analyzed. Thethermalization of this lattice has some peculiarities related to the kind of Morse potential that models the hydrogen bonds between DNA chains. Finally, the problem of quantum thermalization is mentioned when the quantum character of the vibrational motion of the atoms of the molecular chain is taken into account.
Pedagogical technologies for working with gifted students
Authors: Fadeyeva Oksana V.
Published: January 2025

Creating conditions that ensure the identification of gifted children with the subsequent development and realization of their potential is one of the priorities in modern educational conditions. The difficulty of solving these problems is largely due to the lack of uniform methods for identifying giftedness, as well as difficulties in organizing the educational process for such children. The pedagogical community agrees that the peculiarities of the intellectual development of talented students make it necessary to reach a qualitatively different level of teaching, which involves not just the assimilation of information, but the manifestation of the intellectual initiative of students. The emphasis in the professional activity of a teacher when working with such students shifts: here it is necessary not to impart knowledge, but to organize educational activities in a new way. We are talking about the transition from the organization of the traditional educational process to the design of a new educational environment for such a student, in which it will be possible to build an individual educational trajectory. The purpose of such teaching is to provide favorable conditions for the development and improvement of the types of gifts inherent in these students. The paper describes the experience of introducing a number of pedagogical technologies into the educational process, which are based on the basic principles and strategies for teaching gifted children. This was aimed at organizing the educational activities of students with signs of giftedness, taking into account their individual characteristics and made it possible to provide a personal pace of learning and, in part, an individual trajectory for students with signs of academic (mathematical) giftedness. A comparative analysis of the training results of two focus groups showed the effectiveness of using such technologies.
Cartoons as a tool for developing speaking skills among students of non-linguistic specialties
Authors: Doskovskaia Mariia S. , Nenasheva Olga V.
Published: January 2025

The search for innovative and effective tools for developing speaking skills in students of non-linguistic universities leads teachers to use authentic audiovisual materials, including cartoons, in foreign language classes. The choice of a particular cartoon for work is determined primarily by the main goal and objectives of training for a specific stage/lesson, as well as the level of knowledge of students. To prove the effectiveness of a cartoon as a tool for developing speaking skills, we organized and conducted an experimental training in two groups of second-year students of the Higher Biotechnology School of Samara State Technical University. In the experimental group, English classes were held using a set of exercises to develop speaking skills based on the cartoon Shark Tale, 2004, in the control group – using traditional exercises from the main textbook for bachelor students of Samara State Technical University studying in the areas of «Biotechnology» and «Technology of food production and organization of public catering». The results of the experiment showed that the level of development of speaking skills in the experimental group was higher in absolute (average score) and relative (dynamics of changes) dimensions than in the control group, which convincingly demonstrates the need for further active search and use by the teacher in the classroom of new relevant teaching tools that make the process of learning a foreign language effective and interesting for both non-linguistic students and for the teachers themselves.

Published: January 2025

The article is devoted to the study of the current legal regulation of virtual assets in the Principality of Liechtenstein. The authors analyse the advantages and disadvantages of the relevant legal framework, as well as the possibility and feasibility of implementing the most effective provisions of the legislative acts into Ukrainian legislation. Due to the absence of studies that would analyse the main regulatory norms and definitions, as well as the experience of harmonising the current legislation with the European Union regulations, it became necessary to examine the current legal system of the Principality of Liechtenstein, which is known for one of the most progressive virtual asset regulations in the world. To study the current state of legal regulation of virtual assets in the Principality of Liechtenstein, the authors used comparative, analytical, inductive, hypothetical and systemic methods. As a result of the study, specific features of tokens are identified and a possible classification of virtual assets is presented in accordance with the established approach in other jurisdictions. Features of the right to dispose of a virtual asset in comparison with other objects of private law relations are analysed. Further, the particularities of the legislation on Anti–money laundering in this area are outlined. Changes to be made to the existing legislation to harmonise it with the new EU MiCA regulation are considered, including changes to the rules for issuing and trading in virtual assets. It is concluded that the Principality of Liechtenstein has managed to create an adaptive system of legal regulation of virtual assets. The creation of separate legislation on virtual assets, which at the same time refers to the regulation of other objects of private law relations, made it possible to implement it quickly, although harmonisation with the EU MiCA Regulation also requires compliance with the established classification of virtual assets. Although this Regulation eliminates some of the advantages that a particular jurisdiction may have, it simplifies access to the EU market for participants in the circulation of virtual assets. Based on this experience, the Ukrainian legislator needs to create a regulatory system that can be harmonised with the EU regulations for this industry, but at the same time introduce certain preferences that will attract investment in the Ukrainian economy and will not contradict EU regulations.
SCENARIOS OF ECONOMIC RECOVERY OF UKRAINE: BUILD BACK BETTER VS BUSINESS-AS-USUAL
Authors:   Vasyl’ Stus Donetsk National University, Ryabchyn Oleksiy
Published: January 2025

Ukraine had ambitious plans for developing renewable generation, decarbonising the economy and combating climate change even before the start of a full-scale war. To implement the technological transition, economic development and European accession, the post-war recovery of Ukraine should be based on the concept of "building back better" and the principles of green recovery. Although the full-scale reconstruction of Ukraine can only start in the post-war period, fast recovery as a response to the emergency has been going on since nearly the first days of the full-scale invasion.

The government is already planning the post-war recovery of Ukraine and taking measures to restore infrastructure such as energy objects or buildings quickly. Therefore, it is essential to understand the potential impact of recovery processes on the environment and climate. It goes without saying that defence is a number one priority during war. The work concludes that, sustainability, impacts on climate and environment are important considerations for long-term post-war reconstruction. The author argues that it is due to the following factors: European integration aspirations of Ukraine.

It is noted that Ukraine must implement European environmental and climate legislation to join the EU. It is advisable to take it into account during recovery and to ensure reconstruction processes are in line with it; the green component should be duly incorporated in state programs, reforms and projects. This will facilitate access to international financing, which is also relevant for business; incentives should be in place to develop green technologies and innovations to reduce the carbon intensity of existing production and attract investments in new industries. Those could be the production of equipment for RES or components of the electric vehicles. The author stated, that the green stimulus will help make Ukraine's post-war economy more modern, competitive, and integrated into EU value chains.
External barycentric coordinates for arbitrary polygons and an approximate method for calculating them
Authors: Polyansky Ivan S.
Published: January 2025

Background. In the article, the concept of external barycentric coordinates is introduced to generalize the applicability of the barycentric method in solving external boundary value and initial boundary value problems of mathematical physics. Aim of the work is to form a simple analytical relation that allows calculating barycentric coordinates external to a given arbitrary polygonal area with a given accuracy. Methods. The corresponding ratio is formed when drawing up an approximate analytical calculation rule, which is based on the solution by the Fredholm method of the external Dirichlet problem for the Laplace equation. The basis of this solution is the decomposition of the kernel of the Fredholm integral equation of the second kind by Legendre polynomials of the first and second kind, formed using the Heine formula. Results. The convergence rate of the obtained approximate analytical calculation of the external barycentric coordinates is estimated when establishing exponential convergence in Hilbert space and polynomial convergence in the space of continuous functions. The algorithmic features of the implementation of an approximate analytical solution with a structured representation of pseudocodes of programs for calculating external barycentric coordinates, formed mainly for the MathCad computer algebra system, are clarified. The efficiency is demonstrated by specific examples. Conclusion. The author of the article hopes that the detailed results of the algorithmic implementation of the calculation of external barycentric coordinates will arouse interest and make the publication material more accessible to a wide range of readers, which will lead to the development of the barycentric method in solving boundary and initial boundary value problems of mathematical physics.
Influence of crosspolarization of dual-polarized antenna elements on the ergodic capacity of a multichannel system
Authors: Averina Ekaterina  V. , Smuseva Ksenia V. , Tokarev Pavel A. , Uskov Grigory K.
Published: January 2025

Background. Antenna arrays based on dual-polarization elements are used as radiating devices for modern and perspective radio communication systems. The main factor reducing the effectiveness of this approach is the presence of spatial correlation and cross-polarization between elements in the array. These effects can lead to a significant reduction in communication system capacity. Aim. Derive relationships based on the Kronecker model that allow to take into account the polarization properties of antenna elements when calculating the ergodic capacity of a multi-channel communication system. Investigate the influence of the cross-polarization parameter of the antenna element on the capacity. Assess the polarization characteristics of synthesized real antenna elements of various types and their impact on the capacity value. Methods. When deriving the basic relationships, methods of statistical radiophysics and electromagnetic analysis of the propagation channel were used. When synthesizing dual-polarization antenna elements, electrodynamic analysis methods based on Maxwell’s equations were used. Results. Based on the analysis using the derived relationships, it was established that the influence of the cross-polarization properties of the array antenna elements on the capacity of a multi-channel communication system becomes significant when the value of the cross-polarization parameters decreases below 10 dB. It is shown that synthesized real antenna elements of various types have high polarization isolation, which will lead to a slight decrease in the system capacity. Conclusion. The derived relationships and the developed methodology make it possible to estimate the change in the capacity of the communication system when taking into account the cross-polarization properties of the dual-polarization elements of the antenna array. This will allow to optimally select radiating elements for a given system. At the same time, the developed antenna elements of various types satisfy the imposed cross-polarization restrictions.

Financial forecasting using deep knowledge and linear regression methods is explored in this study, which looks at the association between financial metrics and bank presentation from 2003 to 2012. By analyzing a complete dataset, the research identifies macroeconomic variables such as interest rates and rise, together with crucial success drivers such as GDP growth, leverage, and liquidness ratios. We can investigate linear and non-linear connections by mixing several mechanism learning models, such as ARIMA and Random Woodland. However, different banks' risk profiles and strategic prospects can be better understood through situation analysis and PCA-based clustering. The findings prove that rising GDP is a robust measure of economic wealth, but inflation cuts into pays. Institutions that are vulnerable to interest rate variations benefit from interest rates. Gathering shows that various banks adopt separate financial strategies, and scenario analysis shows that monetary results are very sensitive to changes in influence. By faithfully depicting financial doubt, the proposed models demonstrate pliability even during economically unstable times like the 2008 monetary crisis. This research emphasizes the importance of proactive risk organization and specialized forecasting tactics; upcoming studies should use hybrid modeling methodologies and join more macroeconomic variables. In the ever-changing world of finance, these advances aim to improve the correctness of predictions and planned decision-making.

Published: January 2025

Based on the unique properties of protein A which naturally binds to the Fc IgG
fraction of mammals but not to the Fc IgY fraction of chickens. The serum-soft agar (SSA) technique can be used to sort Staphylococcus aureus isolates that have protein A from those that do not. Protein A-positive S. aureus will form compact colonies in SSA with rabbit serum, while those that do not will form diffuse colonies. The use of chicken serum in SSA will produce diffuse colonies, even when S. aureus has protein A. The compact colony reflects the inhibition of bacterial growth in SSA. Such a phenomenon might be related to the formation of interaction complexes between IgG and protein A on the surface of the bacteria, in which these complexes inhibit bacterial growth. No comparable results were shown by the protein A negative S. aureus. The presence of protein A on the surface of bacterial cells was confirmed by the occurrence of Spa gene using polymerase chain reactions (PCR). An isolate of protein A-positive S. aureus was chosen and coated with rabbit IgG specific against Anisakidae antigen to be used as a non-soluble matrix for the preparation of the Anisakidae co-agglutination rapid detection test.

The digital transformation in higher education necessitates a reliable academic advising information system to enhance student support and academic decision-making. This study presents the design of an Academic Advising Information System using a Human-Centered Design (HCD) approach to address various challenges in academic advising, including ineffective communication, fragmented platforms, and inefficient documentation. By applying HCD principles, the system prioritizes usability, accessibility, and emotional considerations, ensuring an intuitive and supportive user experience for both students and academic advisors. This study follows an iterative development framework, integrating user insights through observations, interviews, and iterative improvements to refine system features such as advising history tracking and streamlined communication channels. The results indicate that the application of HCD effectively optimizes advising interactions, reduces administrative burdens, and enhances student engagement. This study contributes to the broader discourse on user-centered educational technology, emphasizing the importance of aligning digital solutions with user expectations. Future research should explore the scalability and adaptability of this system across various academic institutions to validate its broader applicability.

Carbon dioxide reduction reaction (CO2RR) is an efficacious method to mitigate carbon emissions and simultaneously convert CO2 into high-value carbon products. The efficiency of CO2RR depends on the development of highly active and selective catalysts. Copper (Cu)-based catalysts can effectively reduce CO2 to hydrocarbons and oxygen-containing compounds because of their unique geometric and electronic structures. Most importantly, Cu can reduce CO2 to multiple carbon products (C2+). Therefore, this review aims to outline recent research progress in Cu-based catalysts for CO2RR. After introducing the mechanism of this electroreduction reaction, we summarize the influence of the size, morphology, and coordination environment of single component Cu-based catalysts on their performance, especially the performance control of catalysts that contain nano Cu or Cu single-atom sites. Then, the synergistic regulation strategies of doping other metals into Cu-based catalysts are summarized. Finally, the research on the supports used for Cu-based catalysts is reviewed. The prospects and challenges of Cu-based catalysts are discussed.

O estudo investigou como uma dança que envolve a figura mítica amazônica da cobra Boiuna promove aprendizagens mútuas entre crianças e pessoas idosas. O objetivo foi compreender como a dança pode se tornar um instrumento de aprendizagem intergeracional. Utilizou-se métodos qualitativos em pesquisa participante na práxis de professores do Centro de Educação Infantil João e Maria, entre 2022 e 2024, com análises de vivências e revisão bibliográfica de documentos. Entre os resultados, percebeu-se habilidades cognitivas, sociais e emocionais em ambos os grupos; o direito de “brincar” foi alcançado na rotina em diferentes espaços e tempos, e tornou-se eficaz na promoção de competências e habilidades entre diferentes faixas etárias.

O presente relato tem como objetivo apresentar a experiência vivenciada no Programa Institucional de Bolsa de Iniciação à Docência – PIBID, que promoveu atividades pedagógicas de capoeira com a turma do quinto ano, em uma Escola Municipal do Estado do Tocantins no ano de 2023. Tendo como  base  o relatório PIBID e pesquisa bibliográfica, foi elaborado o presente texto. A atividade pedagógica analisada foram os momentos da oficina: “Capoeira na escola”, com objetivo de desenvolver a musicalidade, coletividade, movimento e a história da capoeira articulando com as questões étnico-raciais. Desse modo, promover as atividades envolvendo a capoeira nos espaços de aprendizagens de valorização da cultura e história da formação social afro-brasileira, contribuiu para a aprendizagem e enaltecimento da cultura, assim como para a prevenção e o combate ao racismo nas salas de aulas.

O Projeto de Inovação Pedagógica "O Fascinante Mundo da Programação" tem sido uma iniciativa desenvolvida desde o ano de 2021 até 2023, visando abordar as carências identificadas nos componentes curriculares de alta retenção do Curso de Ciência da Computação, da Universidade Federal do Tocantins. Uma das principais deficiências diagnosticadas foi a falta de habilidades em lógica de programação entre os discentes do curso. Este projeto tem como objetivo reduzir a evasão e melhorar o desempenho dos alunos em disciplinas de alta retenção, como lógica de programação, por meio de uma abordagem integrada de ensino e extensão. As iniciativas incluem monitorias personalizadas, um curso de nivelamento em programação, desenvolvimento de materiais didáticos e ações voltadas à inclusão social. Utilizando metodologias ágeis como Scrum e Kanban, o projeto também promoveu atividades de extensão comunitária, como oficinas e minicursos para os alunos durante a Semana Acadêmica do Curso de Ciência da Computação. Os resultados indicam impacto positivo na experiência acadêmica dos alunos e avanços na educação em programação, consolidando o caráter indissociável entre ensino, pesquisa e extensão.
