Greek Cypriot and immigrant students’ attitudes and perceptions of acculturation, ethnic identity and self-esteem in the Republic of Cyprus
Authors: Taxitari Loukia , Papamichael Androula , Argyrides Marios 
Published: October 2024

Abstract
The multicultural Cypriot society is called upon to face its increasing diversity and manage the relations between its inhabitants (locals and immigrants) for peaceful coexistence. The present study compared acculturation processes of Ιmmigrant students to those of local primary school students aged 11–12 years regarding social adjustment, ethnic identity and self-esteem. Results showed a stronger orientation toward their Country of Origin for both Cypriot and Ιmmigrant students regardless of the nationality of immigrants’. Furthermore, Cypriots and Ιmmigrant students had more group contact with their compatriots than children from other countries. Lastly, the strategies of acculturation and the stages of forming ethnic identity were correlated to Ιmmigrants’ self-esteem levels. The findings highlight the need for new directions in educational policies in the country. The educational system must become flexible and effectively adaptable to the recent changes to form the foundation of cultural coexistence of all the island’s inhabitants, ensuring social cohesion.
A review on the mechanical and biocorrosion behaviour of iron and zinc-based biodegradable materials fabricated using powder metallurgy routes

Published: October 2024

Abstract
Over the past two decades, research on alloys and composites based on Mg, Fe, and Zn has focused on biodegradable orthopaedic implants. Mg-based materials face issues like excessive corrosion rates and hydrogen gas evolution, while Fe and Zn-based materials show lower corrosion rates. However, these rates are slower than the optimal rate, which can be modified using powder metallurgy (PM) manufacturing. The PM process offers precise control over porosity distribution which in turn affects the mechanical and corrosion properties of the fabricated specimen. The highest rate of corrosion i.e. 0.944 mmpy was observed with the alloying of 2 wt% Pd in Fe and by using conventional sintering technique. Similarly, Zn-based samples fabricated by conventional sintering was found to exhibit higher corrosion rate as compared to microwave and spark plasma sintered specimen. PM-fabricated Fe and Zn-based bone scaffolds have been investigated for in-vitro corrosion and osseointegration. A higher porosity in the Fe and Zn scaffolds (>60 %) resulted in high corrosion rate which adversely impacted the cell proliferation. This timely review critically assessed PM-fabricated Fe and Zn-based materials that have the potential to transform regenerative medicine and patient care by redefining the field of biodegradable implants.
‘And I am more than this man can comprehend’: Contemporary Arthurian Texts & Resistance to White Supremacy
Authors: Sheble Margaret , Quigley Logan 
Published: October 2024

Abstract
Beginning with the appropriation of medieval iconography by alt-right movements, particularly in the contexts of Brexit and the January 6 2021 American insurrection, this article highlights how modern adaptations of the Arthurian legend (in particular, Tracy Deonn’s Legendborn, Kazuo Ishiguro’s The Buried Giant, and the video game We Happy Few) resist white nationalist rhetorics. These texts remix figures and symbols from the Arthurian oeuvre to offer stories wherein characters come to recognize and thus resist systematic forgetting, or a societal attempt to overlook uncomfortable facts from the past, thus offering alternative visions of identity and belonging. The ethical implications of historical representation and the power of narrative in contemporary political discourse make these texts powerful works of art that speak to and counter white supremacist attempts to claim and revise medieval iconography to serve their own ends.
Le mot carien pour ‘chef’, une nouvelle racine anatolienne et un changement phonétique carien-grec
Authors: Bianconi Michele 
Published: October 2024

Abstract
In this paper, I analyse the Carian gloss σουαγγελα, attested in Stephen of Byzantium. I propose that possible cognates of γελα ‘king’, the second element of the gloss, may be identified in Hittite, Hieroglyphic Luwian, Lycian, and possibly cuneiform Luwian. This analysis incidentally provides viable etymologies for certain Armenian lexemes, which can now be considered as loanwords from Anatolian languages (specifically Luwian). The new Carian etymology enables the reconstruction of an Anatolian root meaning ‘head’ (vel sim.), accounting for most Anatolian lexical material through conservation or trivial semantic shifts. Additionally, it offers evidence for a sound change that likely occurred during borrowing of words from Carian into Greek. In the final section, I tentatively propose that the first element of the compound σουαγγελα also reflects an authentic Carian word. Through this contribution, I aim to demonstrate that even a seemingly uncertain item like a gloss can prompt a reevaluation of a set of words and uncover previously unnoticed etymological connections.
Spin-bearing molecules as optically addressable platforms for quantum technologies

Published: October 2024

Abstract
Efforts to harness quantum hardware relying on quantum mechanical principles have been steadily progressing. The search for novel material platforms that could spur the progress by providing new functionalities for solving the outstanding technological problems is however still active. Any physical property presenting two distinct energy states that can be found in a long-lived superposition state can serve as a quantum bit (qubit), the basic information processing unit in quantum technologies. Molecular systems that can feature electron and/or nuclear spin states together with optical transitions are one of the material platforms that can serve as optically addressable qubits. The attractiveness of molecular systems for quantum technologies relies on the fact that molecular structures of atomically defined nature can be obtained in endless diversity of chemical compositions. Crucially, by harnessing the molecular design protocols, the optical and spin (electronic and nuclear) properties of molecules can be tailored, aiding the design of optically addressable spin qubits and quantum sensors. In this contribution, we present a concise and collective discussion of optically addressable spin-bearing molecules – namely, organic molecules, transition metal (TM) and rare-earth ion (REI) complexes – and highlight recent results such as chemical tuning of optical and electron spin quantum coherence, optical spin initialization and readout, intramolecular quantum teleportation, optical coherent storage, and photonic-enhanced optical addressing. We envision that optically addressable spin-carrying molecules could become a scalable building block of quantum hardware for applications in the fields of quantum sensing, quantum communication and quantum computing.

This paper reviews recent publications that describe mathematical models with stochastic differential equations (SDEs) and applications in various fields. The purpose of this paper is to briefly describe Rosenbrock-type methods for approximate solution of SDEs. It shows how the performance of the numerical methods can be improved and the accuracy of calculations can be increased without increasing the implementation complexity too much. The paper also proposes a new Rosenbrock-type method for SDEs with multiplicative non-commutative noise. Its testing is carried out by modeling rotational diffusion.

Построены эффективные корреляционно-рандомизированные алгоритмы аппроксимации ансамбля траекторий частиц с использованием корреляционной функции или только корреляционного масштаба среды. Сформулирована простейшая сеточная модель изотропного случайного поля, воспроизводящая заданную среднюю корреляционную длину, что обеспечивает высокую точность решения стохастических задач переноса при малом корреляционном масштабе. Предлагаемые алгоритмы апробированы при решении тестовой задачи о переносе гамма-квантов и задачи оценки сверхэкспоненциального среднего потока частиц в случайной размножающей среде.
The paper presents efficiently realized approximations of random functions, which are developed by the authors and numerically modeled for the study of stochastic processes of particle transport, including criticality fluctuations of processes in random media with multiplication. Efficient correlation randomized algorithms for approximating an ensemble of particle trajectories using the correlation function or only the correlation scale of a medium are constructed. A simple grid model of an isotropic random field is formulated reproducing a given average correlation length, which ensures high accuracy in solving stochastic transfer problems for a small correlation scale. The algorithms are tested by solving a test problem of photon transfer and a problem of estimating the overexponential average particle flux in a random medium with multiplication.

Published: October 2024

Работа посвящена статистическому моделированию пространственно-временных сигналов широкоугольных лидаров при зондировании атмосферной облачности. С помощью вычислительных экспериментов изучаются особенности лидарных сигналов для моностатической и бистатической схем зондирования, которые позволяют анализировать оптические и микрофизические свойства облачной среды. При зондировании тонких облачных слоев лидарный сигнал представляет собой расширяющееся кольцо. Показано, что для бистатического лидара характерно появление второго кольца, которое наблюдается внутри основного в течение короткого промежутка времени.
The paper deals with Monte Carlo modeling of spatiotemporal signals of wide-angle lidars for probing atmospheric clouds. Using computational experiments, we study the features of lidar signals for monostatic and bistatic sensing schemes which make it possible to analyze the optical and microphysical properties of the cloud environment. When probing thin cloud layers, the lidar signal looks like an expanding and attenuating light ring. It is shown that for a bistatic scheme a second ring, which appears for a short time inside the main one, is characteristic of the lidar signal.
КАК ПРОИСХОДИТ ПОТЕРЯ ЮНИТОИДНОЙ МАТРИЦЕЙ СВОЙСТВА ЮНИТОИДНОСТИ?
Authors: ИКРАМОВ Х.Д. , НАЗАРИ А.М. 
Published: October 2024

Юнитоидом называется квадратная матрица, которая может быть приведена к диагональному виду посредством конгруэнтного преобразования. Среди различных диагональных форм юнитоида A имеется лишь одна (с точностью до порядка, принятого для главной диагонали), все ненулевые диагональные элементы которой суть числа с модулем 1. Она называется канонической формой матрицы A относительно конгруэнций, а аргументы ее ненулевых диагональных элементов называются каноническими углами этой матрицы. Если A не вырождена, то ее канонические углы тесно связаны с собственными значениями матрицы A-∗A, называемой коквадратом матрицы A. Хотя определение юнитоида напоминает понятие диагонализуемой матрицы в теории подобий, кажущаяся аналогия между этими двумя матричными классами обманчива. Мы показываем, что жорданова клетка Jn(1), которая в теории подобий рассматривается как антипод диагонализуемости, является юнитоидом. Более того, ее коквадрат Cn(1) имеет n различных унимодулярных собственных значений. Мы погружаем матрицу Jn(1) в семейство жордановых клеток Jn(λ) с параметром λ, меняющимся в диапазоне (0,2]. В некоторой точке, расположенной левее единицы, Jn(λ) перестает быть юнитоидной матрицей. Мы подробно обсуждаем этот момент в попытке понять, как может произойти подобная трансформация. Обсуждаются и аналогичные моменты, соответствующие меньшим значениям λ. Указаны некоторые примечательные факты, связанные с собственными значениями коквадратов и числами обусловленности этих значений.
A unitoid is a square matrix that can be brought to diagonal form by a congruence transformation. Among different diagonal forms of a unitoid A, there is only one, up to the order adopted for the principal diagonal, whose nonzero diagonal entries all have the modulus 1. It is called the congruence canonical form of A, while the arguments of the nonzero diagonal entries are called the canonical angles of A. If A is nonsingular then its canonical angles are closely related to the arguments of the eigenvalues of the matrix A-∗A, called the cosquare of A. Although the definition of a unitoid reminds the notion of a diagonalizable matrix in the similarity theory, the analogy between these two matrix classes is misleading. We show that the Jordan block Jn(1), which is regarded as an antipode of diagonalizability in the similarity theory, is a unitoid. Moreover, its cosquare Cn(1) has n distinct unimodular eigenvalues. Then we immerse Jn(1) in the family of the Jordan blocks Jn(λ), where λ is varying in the range (0,2]. At some point to the left of 1, Jn(λ) is not a unitoid any longer. Wediscuss this moment in detail in order to comprehend how it can happen. Similar moments with even smaller λ are discussed, and certain remarkable facts about the eigenvalues of cosquares and their condition numbers are pointed out.

В работе рассматривается имплементация алгоритма построения адаптивной вычислительной сетки в численное решение прямой одномерной задачи магнитотеллурического зондирования (задачи Тихонова-Каньяра) методом локальных интегральных уравнений, предложенным авторами ранее. Конструирование адаптивной вычислительной сетки основано на геометрических принципах, рассматривающих оптимизацию кусочно-постоянного интерполянта аппроксимируемой функции электрической проводимости среды. Проведены численные эксперименты для исследования и иллюстрации эффективности комбинированного метода. Апробация осуществлялась на модели Като -Кикучи с известным точным решением.
The paper considers an implementation of an adaptive computational grid constructing algorithm inside the numerical solution of the one-dimensional forward magnetotelluric sounding problem (the Tikhonov-Cagniard problem). The numerical solution of the problem is realized by the method of local integral equations, which was proposed by authors earlier. An adaptive computational grid construction is based on geometrical principles, which conduct approximation of the electrical conductivity function via optimization of its’ piecewise-constant interpolant. Numerical experiments are carried out to study and illustrate the effectiveness of the combined method. Approbation was realized on the Kato-Kikuchi model with known exact solution.

Adanya tafsir lathaif al-Isyarat merupakan bentuk dari mendamaikan ilmu syariat dan hakikat dengan tujuan memberikan pemahaman bahwa tidak terjadi kontradiktif antara hakikat dan syariat. Dan pada intinya setiap karya tafsir tidak akan pernah lepas dari latar belakang mufassir sendiri.. Penelitian ini termasuk kajian kepustakaan dengan rujukan primer dan sekunder yaitu tafsir lathaif al-Isyarat sebagai rujukan primer, sedangkan rujukan sekunder menggunakan buku, jurnal yang terpokus pada aspek metodologis. Tujuan dari adanya penelitian ini untuk mengeksplorasi penafsiran Al-Qusyairi terhadap Lataif Al-Isyarat dan metode khusus yang dipakainya dalam penafsiran tersebut. Kajian hasil penelitiannya dapat disimpulkan bahwa Al-Qusyairi adalah seorang sufi yang berupaya menafsirkan ayat-ayat Al Quran dengan menggunakan konsep tasawuf, serta bahasa sastra untuk mengenalkan pembaca pada perasaan jiwa sufi. Urgensinya untuk membela tasawuf pada masa Sultan Thaghral. Kedua, dari segi metode yang dikenalkan menggunakan metode tahlili yang merupakan analisis untuk menjelaskan kandungan ayat Alquran dari berbagai aspek tasawufnya. Kemudian dari segi sumber yaitu bi al-Ra’yi, adapun isyarat akal yang dicantumkan dalam tafsirnya tidak secara murni pekerjaan akal, tetapi supaya isyarat tersebut dihasilkan untuk tidak menjauh dari nas Alquran. Dari segi corak adalah sufi dengan memiliki ide kreatif mempertemukan tasawuf dan psikologi dengan simbol sastra dan menerapkan konsep maqamat serta ahwal.

STUDY OF WAYS TO REDUCE THE VISCOSITY OF SUNFLOWER LECITHIN
Authors: Demydova A. , Yevlash V. , Аksonova O. , Priss O. 
Published: October 2024

Today, lecithin is the most important by-product of oilseed processing due to its numerous technological properties. Food industry technologists use lecithin as an emulsifier, wetting agent, stabilizer, viscosity regulator, crystal formation, etc. One of the main disadvantages of sunflower lecithin is the tendency to increase viscosity (plasticization) during storage. Such lecithin is difficult to use. Therefore, obtaining liquid lecithin with a viscosity of less than 12 Pa s (at 25 °C), which does not increase during its storage, is one of the urgent tasks of enterprises for the extraction and processing of vegetable fats. The article compares diluents of different types. Diluents of fatty nature - sunflower oil, oleic acid and its ethyl ester are characterized by a significantly lower viscosity compared to lecithin, therefore they can act as diluents that do not affect the quality of lecithin. However, their amounts are too large to achieve the goal of obtaining liquid lecithin. These amounts significantly reduce the "acetone insoluble" lecithin index. That is, oils, their acids and esters cannot be recommended for reducing the viscosity of lecithins in industry. It has been shown that the efficiency of divalent calcium salts as diluents is much greater, even at low concentrations of these substances. It has also been proven that the introduction of diluents must be carried out before the stage of drying the wet gum. To obtain liquid lecithin from plasticized lecithin, approximately twice as high concentrations of diluents are required compared to the preventive approach - the introduction of diluents into a wet gum. To obtain liquid sunflower lecithin from a wert gum to which diluents were added, the effective concentrations of diluents are as follows,%: sunflower oil - 13, oleic acid - 5, ethyl ester of oleic acid - 4, calcium chloride - 0.35, calcium acetate - 0.4, calcium orthophosphate - 0.4, concentrated phosphoric acid - 2. It is most expedient to use calcium salts in order to obtain high quality liquid lecithin.
Lean Manufacturing Tools as a Driver of the Company’s Digital Transformation
Authors: Fadeev Stephan 
Published: October 2024

The article substantiates the impact of applying lean manufacturing tools on the digital company’s transformation. The study distinguishes the main lean manufacturing tools that contribute to the optimisation of production processes, reduce losses and improve staff efficiency. Special attention is paid to the synergy of lean methods and digital technologies, which allows companies to adapt to changing market conditions and remain competitive by accelerating and replicating production processes in their digital transformation. The case study of implementing lean manufacturing tools at the Russian food industry enterprises, participants in the national project “Labour Productivity,” demonstrates the feasibility of implementing the key 5 lean manufacturing principles (sorting, organising, standardising, keeping clean and improving), along with the Manufacturing Execution System (MES). The author concludes that companies need to combine lean manufacturing and digital technologies to improve efficiency. Given the fact that lean manufacturing and information technology can conflict, providing their integration will increase the success of the digital company’s transformation. A lean manufacturing approach simplifies production processes, improves the efficiency of digitalisation and increases the likelihood of successful adoption of Industry 4.0 technologies.
