Authors: Михалёв И.В.
Published: March 2024

В современном образовательном ландшафте инклюзивное образование прочно закрепляет свои позиции, вызывая неотложную потребность в квалифицированных кадрах, способных адекватно реагировать на учебные и социальные потребности широкого спектра учащихся. Данная статья фокусируется на разработке модели прогнозирования потребности в специализированных учителях для инклюзивного образования в контексте статистической и социально-психологической динамики. С использованием многофакторного регрессионного анализа, временных рядов и нейросетевых алгоритмов, исследование стремится определить критические параметры, такие как коэффициент инклюзивности образовательных учреждений, рост численности школьников с особыми образовательными потребностями (ООП) — увеличение на 17% за последние 5 лет, и социально-демографические индикаторы. Проанализированы данные из 215 школ, в которых применяются инклюзивные методы, и учтены показатели более чем 15 000 учителей. Исследование проводится на основе методологического синтеза, интегрирующего качественные и количественные методы исследования. Эмпирический материал получен с использованием многоуровневого случайного выборочного анализа, в котором учитываются как интрагрупповые, так и межгрупповые различия. Важность разработки четких критериев и индикаторов для оценки эффективности инклюзивного образования не может быть недооценена, поскольку эти метрики являются ключевыми для мониторинга и последующего адаптирования программ и инициатив.

In the modern educational landscape, inclusive education is firmly established, creating an urgent need for qualified personnel capable of adequately responding to the educational and social needs of a wide range of students. This article focuses on developing a forecasting model for the need for specialized teachers for inclusive education in the context of statistical and socio-psychological dynamics. Using multivariate regression analysis, time series and neural network algorithms, the study seeks to identify critical parameters such as the rate of inclusion of educational institutions, the growth in the number of students with special educational needs (SEN) - an increase of 17% over the last 5 years, and socio-demographic indicators. Analyzed data from 215 schools that use inclusive practices and took into account the performance of more than 15,000 teachers. The research is carried out on the basis of methodological synthesis, integrating qualitative and quantitative research methods. Empirical material was obtained using multilevel random sampling analysis, which takes into account both intragroup and intergroup differences. The importance of developing clear criteria and indicators for assessing the effectiveness of inclusive education cannot be underestimated, as these metrics are key for monitoring and subsequent adaptation of programs and initiatives.

In this paper we provide new evidences that the genetic code represents the unity of chemism and semiosis.
Training Transferable Interatomic Neural Network Potentials for Reactive Chemistry: Improved Chemical Space Sampling
Authors: Hu Quin , Gordon Adrian , Johanessen Andrew , Tan Leqian , Goodpaster Jason
Published: March 2024

Large, condensed phased, and extended systems remain a challenge for theoretical studies due to the compromise between accuracy and computational cost in their calculations. Machine learning methods are on the rise to solve this trade off by training on large datasets of highly accurate calculations that are traditionally hard to obtain. The development of interatomic machine learning potentials has resulted in the ability to model high-quality potential energy surfaces with near ab initio level of accuracy at low computational cost. However, just like other machine learning applications, such methods face challenges when it comes to quality training data and transferability, specifically to systems of chemical space beyond its training. In this work, we present the continuous exploration of utilizing machine learning methods to build and achieve accurate and efficient potential energy surface for bond dissociation and reactive chemistry, and explore sampling techniques that can allow interatomic neural network potentials designed to model potential energy surfaces, such as ANI and NequIP, to accurately predict bond dissociation energy and model reactive chemistry, and to obtain transferability beyond its training data across chemical space.
H and CO Co-induced Adatom Formation on Cu in CO2 Electroreduction Conditions

Published: March 2024

Dynamic restructuring of Cu electrode has been observed under electrochemical conditions, and it has been hypothesized to underly the unique reactivity of Cu towards CO2 electroreduction. Surface roughening is one of the key surface phenomena to Cu activation, in which the surface forms numerous atomic vacancies and adatoms. However, the atomic structure of such surface motifs, in the presence of relevant adsorbates has remained elusive. Here, we explore the chemical space of Cu surface restructuring under coverage of CO and H in realistic electroreduction conditions, by a combination of grand canonical density functional theory and global optimization techniques, from which we construct a potential-dependent grand canonical ensemble representation of the surface. Significant vertical displacement of surface Cu atoms is observed in the regime of intermediate and mixed CO and H coverage. This regime, while predicted to be thermodynamically inaccessible, is kinetically controlled, presenting a tough challenge for theory. To investigate the kinetic trapping effects, we develop a quasi-kinetic Monte Carlo simulation to track the evolution of the system during a simulated cathodic scan. The simulation reveals the path that the system takes across the coverage space and the metastable structures that the system evolves into along the way. Chemical bonding analysis is performed on the metastable structures with elevated Cu*CO species to understand its formation mechanism. By molecular dynamics simulations and free energy calculations, the surface chemistry of the Cu*CO species is explored, and we identifies potential mechanisms via which the Cu*CO species may diffuse or dimerize. This work provides rich atomistic insights into the surface roughening phenomenon and the structure of the involved species. It also features generalizable methods to explore the chemical space of restructuring surfaces with mixed adsorbates, and its evolution in non-equilibrium.

Published: March 2024

Mono-layer protected metal clusters comprise a rich class of molecular systems, and are promising candidate materials for a variety of applications. While a growing number of protected nanoclusters have been synthe- sized and characterized in crystalline forms, their dynamical behavior in solution, including pre-nucleation cluster formation, is not well understood due to limitations both in characterization and first-principles mod- eling techniques. Recent advancements in machine-learned interatomic potentials are rapidly enabling the study of complex interactions such as dynamical behavior and reactivity at the nanoscale. Here, we develop an Au-S-C-H Atomic Cluster Expansion (ACE) interatomic potential for efficient and accurate molecular dynamics simulations of thiolate-protected gold nanoclusters (Aun (SCH3)m ). Trained on more than 30,000 density functional theory calculations of gold nanoclusters, the interatomic potential exhibits ab initio level accuracy in energies and forces, and replicates nanocluster dynamics including thermal vibration and chiral inversion. Long dynamics simulations (up to 0.1 μs time scale) reveal a novel mechanism explaining the ther- mal instability of neutral Au25(SR)18 clusters. Specifically, we observe multiple stages of isomerization of the Au25(SR)18 cluster, including a novel chiral isomer. Additionally we simulate coalescence of two Au25(SR)18 clusters and observe series of new clusters where the formation mechanisms are critically mediated by ligand exchange in the form of [Au–S]n rings.

Published: March 2024

With growing interest in carbon-based materials for energy storage and active research in the field of advanced optoelectronic devices, we theoretically designed ten complexes by cyclo[18]carbon (C18) inside and outside complexing alkali-metal ions (M+ = Li+, Na+, K+, Rb+, and Cs+), respectively referred to as M+@C18in and M+@C18out, and performed careful analyses of binding interaction between M+ and C18 as well as optical properties of stable endohedral complexes M+@C18in. The effects of atomic number of alkali-metals on electronic structures, binding interactions, electronic absorption spectra, and molecular (hyper)polarizabilities of the M+@C18in were studied using accurate density functional theory (DFT) calculations. The research results indicated that the differences in radius and properties of M+ lead to different binding modes and strengths with C18, but there is no difference in electronic absorption spectra between the complexes; the polarizability and second hyperpolarizability of M+@C18in containing different alkali-metal ions are similar due to their analogous electronic structures, but their first hyperpolarizability differ greatly due to discrepancies in molecular symmetry. The similarities and differences in intramolecular interactions, electronic absorption spectra, and (hyper)polarizability of M+@C18in were explored using advanced wavefunction analysis methods.

Authors: Jahnavi R.
Published: March 2024

Cloud computing is revolutionizing Customer Internet computing and the IT industry by integrating with mobile environments through remote access technologies. This growth involves using smartphones and sensors as data collection nodes interacting with the cloud. However, widespread adoption faces a hurdle in data security concerns, as users are hesitant about entrusting sensitive data to public clouds operated by external providers. To tackle barriers in cloud computing, we urgently require innovative and secure management architectures. This paper introduces a comprehensive framework addressing user concerns, focusing on secure data sharing in the cloud. The framework covers aspects like transport, aggregation, usage, and destruction of sensitive data, emphasizing the semi-trusted nature of the cloud to boost user confidence and address security concerns. One key aspect of the proposed framework is the integration of the Kerberos protocol over the network. This protocol plays a pivotal role in establishing secure and authenticated communication channels, ensuring the confidentiality and integrity of the data being transferred within the cloud infrastructure. Additionally, the paper introduces a user process protection method based on a virtual machine monitor. This method contributes to enhancing overall system security by providing a layer of isolation and protection for user processes operating in the cloud environment. The combined integration of the Kerberos protocol and the virtual machine monitor-based user process protection method forms a cohesive approach towards realizing robust system functionalities. By offering a secure foundation for data management in the cloud, this framework addresses the current limitations and instills a sense of trust among users, fostering a more widespread and confident adoption of cloud computing techniques.

«Нечего вынимать из румынской ноги бессарабскую занозу»: бессарабське питання у радянсько-румунських відносинах міжвоєнного періоду
Authors: Снігир Максим
Published: March 2024

У статті охарактеризовано особливості розвитку радянсько-румунських відносин у контексті «бессарабського питання» протягом 1918-1940-х років. Радянський Союз зберігав послідовну позицію невизнання приналежності Бессарабії до Румунії та вимагав включення Бессарабії до складу СРСР на правах автономії у складі УСРР або окремої союзної республіки. Задля реалізації цієї мети більшовики вдавалися до диверсійно-розвідувальної діяльності, підтриманої пропагандистською кампанією, спрямованою на населення Бессарабії, СРСР та західноєвропейську громадську думку.

Серед очільників радянського Наркомату закордонних справ на початку 1920-х років сформувалося два підходи до розв’язання бессарабського питання. Повноважний представник СРСР в Лондоні Християн Раковський стояв на позиції необхідності використання Бессарабії як фактору дестабілізації ситуації як в Румунії, так і у відносинах між румунською елітою та її закордонними союзниками. Цій концепції опонував заступник наркома закордонних справ Максим Литвинов, який закликав до вирішення бессарабського питання навіть ціною безумовного визнання приналежності регіону Румунії. Попри наявність двох різних підходів до розв’язання «бессарабського питання» серед керівників союзного Наркомату закордонних справ, фактично і позиція Християна Раковського, і погляди Максима Литвинова виходили з тимчасовості статус-кво та необхідності входження Бессарабії до складу СРСР. Хоча на початку 1930-х років СРСР з тактичних міркувань встановив дипломатичні відносини з Румунією, Наркомат закордонних справ обрав політику невизнання приналежності Бессарабії до румунської держави. Ця політика стала можливою завдяки джентльменській домовленості між очільниками зовнішньополітичних відомств Румунії та СРСР – Ніколае Тітулеску та Максима Литвинова. Однак навіть після встановлення дипломатичних відносин, Радянський Союз продовжував підважувати суверенітет Румунії над Бессарабією.

Published: March 2024

У статті досліджено процес з’ясування на основі всебічного аналізу, узагальнення та критичного осмислення доступних джерел і наукових досліджень основних характеристик Революції Гідності, окремих етапів в євроінтеграції України з 2013 по 2022 роки та вплив «гібридної війни» на захист європейський цінностей України.

У статті використано методи синтезу та аналізу, конкретно- і спеціально-історичні методи, зокрема, історико-генетичний, історико-типологічний, історико-порівняльний, ретроспективний, структурно-функціональний, конкретно-пошуковий та проблемно-хронологічний методи.

Українська революція на зламі 2013-2014 років, відома як «Євромайдан», є особливим політичним явищем, яке було виражене у формі мирного народного супротиву. Україна зберегла свою самостійність від імперської Росії, позбавившись Віктора Януковича та його оточення, які постійно жертвували національними інтересами країни й готові були їх віддати повністю, а також підтвердила свій шлях у напрямку європейського розвитку. Росія не припинила спроб повернути Україну в своє впливове коло, захопивши невдовзі після подій на Майдані Крим та окупувавши частину території Донбасу. Однак військові, які захищали ці принципи, що відстоював Майдан, залишаються на передовій й досі борються з ворогом за українські цінності.

Міжнародна спільнота відзначила та підтримала прагнення українського народу до європейської інтеграції після подій Революції Гідності. Це стимулювало активніші зусилля країни у напрямку вступу до Європейського Союзу та НАТО.

У статті розглянуто основні причини, які спонукали український народ до мирних протестів, що переросли в Євромайдан та отримали назву “Революція Гідності”. Проаналізовано гібридну війну Росії проти України в 2014-2022 рр. та її значення для захисту європейських цінностей України.

Аксіологічні пошуки моделі освіти майбутньої України
Authors: Чекаленко Людмила
Published: March 2024

Стаття присвячена одній з найактуальніших тем сьогодення – сучасному і майбутньому стану освіти в світі і, зокрема, в Україні. Авторка подає характеристики різнопланових освітніх схем, популярних в Європі і Америці, розповідає передісторію їх становлення. Згадує про Болонську систему освіти, запроваджену в Україні, а також розмірковує про майбутній вибір освітньої моделі в Україні після війни.

Значна увага при цьому приділена освітній діяльності ЮНЕСКО. Нагадаємо, що ця міжнародна організація з науки, культури і освіти активно підтримала ідею впровадження Болонського процесу в освітню систему європейських освітніх інституцій. Зазначена система була запроваджена і в Україні. Відомо, що існують й інші освітні моделі, що себе позитивно зарекомендували: такі система освіти, як Гумбальдтовська, Ньюменовська, Французька (Наполеонівська), Американська тощо. І після розвалу радянського союзу керівництво української держави не мало часу розмірковувати щодо майбутнього освітнього процесу. В результаті цікавий Болонський варіант, що був прийнятий в Україні поспіхом і без відповідної підготовки, виявився змішаною схемою з колишньою радянською системою освіти.

Враховуючи сучасний воєнний стан, який так чи інакше завершиться, необхідно замислитись про майбутній розвиток освіти в Україні. І вже сьогодні виробити власну модель освіти із врахуванням руйнівних наслідків війни і позитивних складових відомих передових освітніх технологій, зокрема і Болонського процесу.

Published: March 2024

Microwave radiation can have harmful effects on our bodies. With increased exposure due to online activities, it is essential to use absorber materials like perovskite manganate to reduce radiation. In this study, perovskite manganate La(1-x)Bax/2Srx/2Mn0.4Ti0.6O3 (x = 0, 0.1, and 0.3) was synthesized using the sol-gel method. X-ray diffraction (XRD) analysis revealed that the two samples were multi-phased, LaMnO3 and La2Ti2O7, and were formed, exhibiting a rhombohedral crystal structure (R -3 c). Morphological characterization of the sample surface using a Scanning Electron Microscope (SEM) showed that as doping increases, the grain size decreases from 282.02 to 245.63 nm at x=0 and x=0.3, respectively. This result implies that doping leads to more uniform grain distribution and enhanced grain refinement. Characterization via Vibrating Sample Magnetometer (VSM) revealed that the maximum saturation value, 0.79 emu/g, was attained when x = 0. This sample exhibits soft magnetic properties, as evidenced by its coercivity (Hc) value of < 1kOe. Results from the Vector Network Analyzer (VNA) indicate that the absorption capacity of La(1-x)Bax/2Srx/2Mn0.4Ti0.6O3 increases, with a maximum reflection loss value of -25.5 dB with 1.5 mm thickness. Consequently, La(1-x)Bax/2Srx/2Mn0.4Ti0.6O3 demonstrates potential as a microwave absorber material.

ZnO nanostructures show a wide range of applications as active materials in optoelectronic devices. The unique structures in 1-dimensional (1D) in combination with other potential materials (such as graphene-based) can increase several device performances. This research aims to observe the influence of an additional electric field (induced by different voltages of ±1 kV) during the growing process of the zinc oxide (ZnO): graphene oxide (GO) crystal. The ZnO:GO layers were prepared via the self-assembly method in 2 steps; the first was seed layer preparation by dip coating technique using Zn (CH3COO)2.2H2O and 0.5 (wt%) of AlCl3 as precursor and dopant, respectively. Secondly, growing ZnO rods using Zn (NO3)2·6H2O as precursor, 0.5 (wt%) GO (dispersed in water) as dopant materials, and hexamethylenetetramine (HMTA) as complexing agent. Applying an external field during self-assembly accelerated the ZnO hexagonal wurtzite crystal formation in a vertical growth direction, increasing the aspect ratio (L/d) of ZnO:GO rods. The direction of the applied external field affected the structure and morphology of the ZnO rods, which relates to ions and seed layer surface polarity during the synthesis process. The addition of an external field during the growing process induced the orderly alignment of ZnO rods, controlling growth perpendicular to the basal plane.

Which vocabulary learning strategies are important and useful for Japanese university students? A text-mining approach
Authors: Ueno Shotaro , Takeuchi Osamu
Published: March 2024

A growing body of vocabulary learning strategies (VLSs) studies focuses on accumulating empirical evidence on the relationship between frequency of VLS use and vocabulary acquisition by using the frequency-based measures of VLSs. Our study by contrast, examined which VLSs are perceived as important and useful, and how they are employed by Japanese university students learning English as a foreign language (N = 40). Further, we investigated whether university students’ perceptions and use of strategies vary between higher- (n = 16) and lower-proficiency groups (n = 24). To this end, we used the KH Coder software and produced co-occurrence networks to categorize the words extracted from the results of an open-ended questionnaire. The results revealed that Japanese university students perceived cognitive strategies related to word form, sound, association learning, and metacognitive strategies as important and useful, and employed them frequently. Results from the two proficiency groups showed that while the higher-proficiency group perceived the importance of metacognitive strategies, these tendencies were not observed in the lower-proficiency group. Given the possibility that learners’ proficiency influences the use of VLSs in the vocabulary learning process, considerations and suggestions for future VLSs studies and teaching are discussed.
