Early experiences matter: Fostering positive relationships and secure attachments with babies and toddlers
Authors: Kirby Gemma
Published: December 2023

It is sometimes easy to forget that the young children who attend our settings are still adjusting to life outside of the womb. Undoubtedly this must be extremely overwhelming for them, especially when babies may be thrust into a 1:3 staff ratio at just a few months old. Gemma Kirby, lecturer in Education at University College Birmingham and former nursery manager, explores the importance of practitioners striving to foster positive relationships and forming secure attachments with babies and toddlers.

Published: December 2023

Two new species of Mimosa sect. Batocaulon ser. Leiocarpae are described from northeastern Brazil. Mimosa cardosoi occurs in the seasonally dry woodlands known as Caatinga from the upland areas of central Bahia state. It is close to M. mensicola from which differs by leaves with smaller and more numerous leaflets and by the shape of the leaflets, calyx, and corolla. Mimosa simonii is known only from the Araripe plateau along the Ceará-Pernambuco states border. It is similar to M. verrucosa from which it differs by spiculate leaves, larger leaflets, and corolla stellate-pubescent over its entire length.
The epistemology of evidence-based policies and practices: a comment on ‘When is it justified to claim that a practice or policy is evidence-based? Reflections on evidence and preferences’ by Christian Gade

Productive interactions in a port city: a proximity approach to coordination in science-policy collaborations
Authors: Smit Jorrit P. , Westerduin Hedi , van Buuren Arwin
Published: December 2023

Background:

Many different concepts have been invoked in the literature to describe coordination between scientific and policy practices. However, a framework to understand different types of this boundary management is lacking, which allows ‘linear’ models and ‘gap’ metaphors to persist.

Objectives:

To operationalise the multidimensional ‘proximity’ approach from innovation studies in the context of coordination work between science and policy and employ it in a case study of hybrid research spaces in the port city of Rotterdam.

Method:

Semi-structured interviews and focus groups with scientists, policymakers and policy researchers involved in collaborative knowledge labs.

Findings:

Different proximity dimensions can both stimulate and impede productive interactions in collaborations between science and policy actors. There is no uniform mechanism to overcome coordination problems and different knowledge labs use different combinations of proximities.

Discussion and conclusions:

We conclude that the concepts of cognitive, social, organisational and geographic proximity enable a fine-grained articulation of the balancing act required for successful and enduring collaborative knowledge work between scientists and policymakers. The operationalisation of proximity for structured science-policy interactions led us to the insight that an analytical distinction can be made between ordering and operating enactments of proximity. Ultimately, we interpret this as two types of politics of knowledge production, and call on policymakers, researchers, and other involved parties to take this into consideration when organising structural knowledge collaborations between research and policy practices.
Residual optical absorption from native defects in CdSiP2 crystals

Published: December 2023

CdSiP2 crystals are used in optical parametric oscillators to produce tunable output in the mid-infrared. As expected, the performance of the OPOs is adversely affected by residual optical absorption from native defects that are unintentionally present in the crystals. Electron paramagnetic resonance (EPR) identifies these native defects. Singly ionized silicon vacancies (VSi−) are responsible for broad optical absorption bands peaking near 800, 1033, and 1907 nm. A fourth absorption band, peaking near 630 nm, does not involve silicon vacancies. Exposure to 1064 nm light when the temperature of the CdSiP2 crystal is near 80 K converts VSi− acceptors to their neutral and doubly ionized charge states (VSi0 and VSi2−, respectively) and greatly reduces the intensities of the three absorption bands. Subsequent warming to room temperature restores the singly ionized charge state of the silicon vacancies and brings back the absorption bands. Transitions responsible for the absorption bands are identified, and a mechanism that allows 1064 nm light to remove the singly ionized charge state of the silicon vacancies is proposed.
Bit Error Rate of M-Pulse Position Modulated Laser Beams for Vertical Links Operating in Weak Oceanic Turbulence
Authors: Gerçekcioglu Hamza , Baykal Yahya
Published: December 2023

The on-axis scintillation index of laser beams is investigated by employing the Rytov method in weakly turbulent oceanic medium for up/downlink coupling of laser communication between any underwater vehicles or divers. For vertical link, the formulation of the on-axis scintillation index of laser beams is derived analytically and evaluated for plane, collimated Gaussian and spherical beams in specific medium, including the Atlantic Ocean at mid and low latitudes associating temperature and salinity changes at low latitude, at mid latitude-summer and at mid latitude-winter. Using the scintillation index, bit error rate (BER) performances of M-pulse position modulation (M-PPM) are investigated for these types of laser beam. The variations of the scintillation index against the uplink/downlink propagation distances, source size and zenith angle are examined, and BER variations versus the Kolmogorov microscale and the symbol orders, and results are compared. It is noted that the behavior of the scintillation index that depends on the relative strength of temperature and salinity fluctuations which changes in depth, is different for uplink/downlink, and for each latitude due to its distinct characteristics. Source size that minimizes the scintillation index values is in the range of about 0.1 cm-0.2 cm for all latitudes.

Authors: Rosner Guy , Scapa Erez , Ziv Tomer , Gluck Nathan , Ben-Yehoyada Merav
Published: December 2023

INTRODUCTION:

Pancreatic ductal adenocarcinoma (PDAC) has a poor 5-year survival rate. PDAC surveillance is recommended in high-risk individuals (HRIs) with strong PDAC family history or a pathogenic germline variant (PGV) in a PDAC susceptibility gene. We aimed to explore a potential correlation between genetic status, extent of family history, pancreatic findings, and surveillance implications in heterogeneous PDAC HRIs.

METHODS:

A total of 239 HRIs from 202 families were tested genetically and underwent prospective pancreatic surveillance for 6 years.

RESULTS:

The cohort was divided into 3 groups: familial pancreatic cancer (FPC; 70 individuals, 54 families), familial non-FPC (81 individuals, 73 families), and hereditary pancreatic cancer (PC) (88 individuals, 75 families). PGVs were detected in 37.6% of all families, including 11.1% of FPC families and 9.6% of familial non-FPC families. The hereditary PC group had earlier onset of PDAC compared with the other 2 groups. BRCA2 PGV carriers showed earlier onset of PDAC and pancreatic cysts. Of the 239 HRIs, PDAC was detected in 11 individuals (4.6%), with 73% diagnosed at an early stage; 4 (1.67%) had pancreatic neuroendocrine tumor; 6 (2.5%) had main-duct intraductal papillary neoplasm (IPMN); and 41 (17.15%) had side-branch IPMN. Seventeen individuals were referred to surgery, and 12 were alive at the end of the study.

DISCUSSION:

The percentage of PDAC was similar in the 3 groups studied. The hereditary PC group, and particularly BRCA2 PGV carriers, had an earlier age of PDAC onset. PGVs were detected in a significant percentage of HRIs with PC. Surveillance seems effective for detection of early-stage PDAC and precursor lesions.
Extraction of Fringing-Effect Power Loss from Total Dissipation in Magnetic Component
Authors:   Politechnika Łódzka, Kasikowski Rafał
Published: December 2023

Power magnetics in the energy storage configuration are not able to handle a significant amount of power without the introduction of a physical discontinuity in their magnetic path. This frequently takes the form of a discrete air gap giving rise to certain consequences such as extra power dissipation in the coils mounted on gapped cores. The ascertainment of the impact of the fringing magnetic field at the air gap on the efficiency of power conversion is highly problematic due to the complex nature of the phenomenon. The fringing-effect power loss typically coexists and is combined with all the other power-dissipation mechanisms, which greatly complicates the extraction of losses brought about solely by the fringing flux at the air gap from the total amount of dissipation in a given magnetic component. Magnetic cores of composite materials do not require a discrete air gap, as the air gap in them is distributed throughout the entire material, thus preventing the fringing magnetic flux from forming. However, there is a downside to this approach, as power loss in the material is comparably greater and so are the manufacturing costs. As shown here, distributed-gap-type core materials, due to the absence of physical discontinuity, and hence the lack of registerable fringing-effect power loss, can be utilized to comparatively ascertain and extract the extra power dissipation due to the fringing effect phenomenon in gapped magnetic components.
Optimal State Estimation via Adaptive Fuzzy Particle Filter
Authors:   Carleton University, Ottawa, Ontario, Canada, Sąsiadek Jurek , Bitlmal Hamdan
Published: December 2023

Particle Filters (PF) accomplish nonlinear system estimation and have received high interest from numerous engineering domains over the past decade. The main problem of PF is to degenerate over time due to the loss of particle diversity. One of the essential causes of losing particle diversity is sample impoverishment (most of particle’s weights are insignificant) which affects the result from the particle depletion in the resampling stage and unsuitable prior information of process and measurement noise. To address this problem, a new Adaptive Fuzzy Particle Filter (AFPF) is used to improve the precision and efficiency of the state estimation results. The error in AFPF state is avoided from diverging by using Fuzzy logic. This method is called tuning weighting factor (α) as output membership function of fuzzy logic and input memberships function is the mean and the covariance of residual error. When the motion model is noisier than measurement, the performance of the proposed method (AFPF) is compared with the standard method (PF) at various particles number. The performance of the proposed method can be compared by keeping the noise level acceptable and convergence of the particle will be measured by the standard deviation. The simulation experiment findings are discussed and evaluated.

In this paper consider is the application of the Polynomial Maximization Method PMM to find estimates of the parameters of non-Gaussian Moving Average model. This approach is adaptive and is based on the analysis of higher-order statistics. The case of asymmetry of distributions of Moving Average of the stochastic processes is also considered. It is shown that the asymptotic variance of estimates of the Polynomial Maximization Method (2nd order) have such analytical expressions, whose allow to finding estimates and analyzing their uncertainties. Above approach can be significantly less than the variance of the classic estimates based on minimizing the Conditional Sum of Squares or Maximum Likelihood (in the Gaussian case). The increase of accuracy depends on the values of the coefficient’s asymmetry and the kurtosis of residuals. The results of statistical modeling by the Monte Carlo Method confirm the effectiveness of the proposed approach.
Generation of Waves in the Gravitational Field of the Universe
Authors: Palchoudhury Sankar
Published: December 2023

The gravitational field naturally perturbs due to the wave (light, x-ray, infrared, etc.). The gravitational field encompasses everything. Wave formation, like to that of the natural world. In the natural world, when wood and plants burn, a chemical reaction produces CO2, CO, and other gases. During this chemical process, tiny particles (atoms, molecules, etc.) vibrate, and their vibrations get intense enough to cause the gravitational field to be disrupted. This kind of vibration creates waves in the surrounding gravitational field and propagates them forward with a specific initial power, wavelength, and amplitude.

This research aims to create a model for the development of halal tourism destinations based on the perspectives of the actors of the Sapi Sonok culture in Pamekasan, Madura. The challenge for tourism development after the pandemic is forming a concept that adheres to local wisdom. Cultural tradition can inspire the development of tourism destinations without exploiting the values of the local residents. The phenomenological approach was employed through an interpretive paradigm, and four informants were recruited through purposive sampling. Data were collected through in-depth interviews, documentation, and observation. Meanwhile, analysis techniques use bracket; intuitive; analysis; and description. The research reveals, first, the artistic philosophy of the actors forms social cohesion even though there is competition within it. The actors’ philosophy includes beauty contests and the beauty of animals; tancek-guyup, harmony, and gratitude as well as social cohesion. Second, harmonious forms of cultural identity are adapted to local values. Halal tourism communication methods include observation, accessibility, amenities, and promotion of business actors. Finally, the right model is the one to develop halal tourism destinations based on the cultural actors of the Madurese Sapi Sonok culture which refers to the strength of the internal community and external groups.

Published: December 2023

The encouragement of creative, scientific, inventive activity and business competition largely depends on the solid protection of intellectual property and related rights on the internet. The problem of such protection lies in the transnational nature of the internet, the absence of a unified centralized management, the difficulty of proving infringements, as well as in the insufficient regulation of this issue. This article analyses the protection of intellectual property rights on the internet in Ukraine, the potential and real threats to them in the cybernetic domain, and the key areas of related activity of state bodies and individuals. The research uses a method of synthesis and analysis, comparative legal analysis, and systemic and formal-logical methods. This article analyses the normative legal documents of Ukraine on intellectual property and rights on the internet, points out their shortcomings, and provides advice on their use. Recommendations are given on how to ensure the protection of intellectual rights through preventive measures and subsequent judicial and extrajudicial proceedings, indicating ways to ensure cybersecurity in relation the intellectual property of individuals.
Material Influence on the Micropitting and Wear Resistance of Nitrided External and Internal Gears
Authors: Geitner M. , Zornek B. , Hoja S. , Tobie T. , Stahl K.
Published: December 2023

Due to increasing performance requirements and sometimes tribologically challenging operating conditions in gears (such as those found in wind turbines), alternative heat treatment processes to quenching and tempering or case hardening are becoming more and more important. Nitriding can significantly increase the load-carrying capacity of gears compared to the quenched and tempered initial state. The nitrided surface layer is characterized by a hard compound layer on the surface that is just a few micrometers thick and a diffusion zone that extends deeper into the material. The structure of the compound layer of iron and alloy element nitrides is primarily decisive for the wear behavior of nitrided components.

Previous studies on nitrided gears with regard to micropitting and wear focus primarily on a systematic variation of the compound layer on gears made of nitriding steel 31CrMoV9. Results on the influence of the base material on the micropitting and wear resistance of nitrided gears are not yet available.

In systematic load and speed stage tests, nitrided gears made from a quenched and tempered steel (42CrMo4) and a material with an alternative alloy composition (34CrNiMo6) were examined in addition to the reference (nitriding steel 31CrMoV9). Both external and internal gear pairings were tested, with the alternative materials showing more favorable tribological behavior in some cases. The results are presented and categorized according to the current state of the art. Finally, recommendations for the practical use of nitrided gears are derived.
Unusual onset of Graves’ disease associated with thymic hyperplasia in a 5-year-old girl with congenital bilateral clinical anophthalmia: diagnostic and therapeutic challenges
Authors: Ben Rabeh Rania , Bouzidi Ahmed , Hamdi Rim , Missaoui Nada , Bouyahia Olfa , Mazigh Sonia , Boukthir Samir
Published: December 2023

Objectives

Graves’ disease (GD) is a rare auto-immune disorder in pediatric population. The association between GD and thymic hyperplasia was rarely reported in children. Diagnosis and management of GD are challenging in children.

Case presentation

This report presents the case of a 5-year-old girl with a personal history of asthma and congenital bilateral isolated clinical anophthalmia who presented with acute congestive heart failure, sinus tachycardia and atypical signs of orbitopathy with edema and erythema of the lower right eyelid and excessive tearing. The diagnosis of GD was based on detecting a suppression of serum TSH level and the presence of high titers of TRAbs. Relapse occurred after 10 months of antithyroid drugs with chief complaints of palpitations, dyspnea and dysphagia. Computed tomography showed heterogeneous anterior mediastinal mass with no invasion into the surrounding tissue. The marked shrinkage of the mass after radioiodine therapy supported the diagnosis of thymic hyperplasia associated with GD.

Conclusions

The presence of clinical anophthalmia may be a confusing factor for the diagnosis of Gravesʼ ophthalmopathy. Recognition of the association between GD and thymic hyperplasia would avoid invasive diagnostic procedures and unnecessary surgical resection. Radioiodine therapy may be used in young children with repeated relapses of GD.
Prominently enhanced luminescence from a continuous monolayer of transition metal dichalcogenide on all-dielectric metasurfaces
Authors: Iwanaga Masanobu , Yang Xu , Karanikolas Vasilios , Kuroda Takashi , Sakuma Yoshiki
Published: December 2023

2D materials such as transition metal dichalcogenides (TMDCs) are a new class of atomic-layer materials possessing optical and electric properties that significantly depend on the number of layers. Electronic transitions can be manipulated in artificial resonant electromagnetic (EM) fields using metasurfaces and other designed nanostructures. Here, we demonstrate prominently resonant enhancement in the photoluminescence (PL) of atomic monolayer, WS2, doped with a small quantity of Mo. The excitonic PL showed a strong enhancement effect on a higher-order magnetic resonance of all-dielectric metasurfaces consisting of periodic arrays of Si nanopellets. The PL intensity witnessed a 300-fold enhancement compared to the reference PL intensity on a flat silicon dioxide (SiO2) layer, which suggests a drastic change in the dynamics of photoexcited states. Confocal PL microscopy and the analysis revealed that the single photons were coherently emitted from the TMDC monolayer on the metasurface. Furthermore, examining the PL lifetime in the ps and ns timescales clarified two exponential components at the prominent exciton PL: a short-time component decaying in 22 ps and a long-time component lasting over 10 ns. Therefore, we can infer that the radiative components were significantly activated in the TMDC monolayer on the metasurfaces in comparison to the reference monolayer on a flat SiO2 layer.
Semiotic approach of strategic narrative: the news discourse of Russia’s coronavirus aid to Italy
Authors: Ventsel Andreas
Published: December 2023

Crucial components of strategic communication include the audience, which plays a decisive role in how any conflict plays out. Strategic narratives are seen as means by which political actors attempt to construct a shared meaning of international politics to shape the behaviour of domestic and international actors. The article analyzes the news discourse of the Russian media sources RT, Pervyj Kanal, and NTV on Russia’s coronavirus aid to Italy in spring 2020. In the context of media coverage, some methodological questions arise: How should the intentional structuring of narratives, targeting of audiences, and the manipulative intentions of the strategic actor be studied? For this purpose, the article combines strategic narrative theory with Umberto Eco’s concepts of the Model Reader and the Model Author. Analysing the aims and intentionality of the strategic narratives, we postulate the Model Reader as an analytical category that organizes the study of the audience’s interpretation process. The function of the Model Reader is to actualize the codes and intertextual references that the author has strategically planned in the news message, in order to achieve the geopolitical aims of the strategic narratives in question. The analysis of constructing the Model Reader and the Model Author of strategic narratives is complemented by Greimas’ semiotic theory of the narrative and the composition principles of Lotman’s discrete/non-discrete texts.

Published: December 2023

Adolescent cocaine exposure (ACE) induces anxiety and higher sensitivity to substances abuse during adulthood. Here, we show that the claustrum is crucial for controlling these psychiatric problems in male mice. In anxiety-like behavioral tests, the CaMKII-positive neurons in the median portion of the claustrum (MClaustrum) were triggered, and local suppression of these neurons reduced the anxiety-like behavior in ACE mice during adulthood. In contrast, the CaMKII-positive neurons in the anterior portion of the claustrum (AClaustrum) were more activated in response to subthreshold dose of cocaine induced conditioned place preference (CPP), and local suppression of these neurons blocked the acquisition of cocaine CPP in ACE mice during adulthood. Our findings for the first time identified the fine-regional role of the claustrum in regulating the anxiety and susceptibility to cocaine in ACE mice during adulthood, extending our understanding of the claustrum in substance use disorder.
Gross-Hessen diocese of the Russian Orthodox Church Abroad in the time of archbishop Filofei (Narko), 1946–1949
Authors: Kornilov Aleksandr
Published: December 2023

The article studies the creation and development of the Gross-Hessen Diocese of Vicar of the Russian Orthodox Church Abroad (ROCOR) in the years of 1946-1949. It is noted that at the end of the 2nd World War on the territory of Western zones of occupation in Germany, thousands of Orthodox refugees were in need of pastoral and spiritual care and guidance. Synod of ROCOR decided to form a set of vicar’s dioceses, so that in the region of Gross-Hessen, the one was established and was headed by the bishop of the Belarusian Autonomous Orthodox Church by Archbishop Philofei (Narko). Contrary to financial and other social difficulties, the Vicar managed to organize regular liturgical life and largely unite different Orthodox parishes of the Displaced Persons. Some organizational decisions made by Archbishop Philofei are analyzed. In particular, the decision was made to hold regular meetings of the clergy, to form an advisory body under the Vicar Bishop (Vicarian Council in Wiesbaden). The Archbishop organized with success distribution of food assistance to parishes of his diocese in the economically difficult 1949.Based on original documents preserved in the Archives of the German Diocese of the ROCOR, the author provides statistics on the number of parishes, specific names of the clergy who developed parishes in Wiesbaden, where the residence and the Cathedral of Vicar was established, in Darmstadt, Frankfurt, Menhegoff, Furstenwald, Gudensberg and in other places were discovered. The problems that prevented a successful development of the liturgical and out-service life of the Vicar’s diocese are studied, namely: lack of clergy after mass departure of priests and parishioners from Germany to countries of the Western Hemisphere in 1947-1949; conflict over activities of the Orthodox Missionary Group of Hessen-Nassau; problem of the development of Belarusian parishes due to desire of part of the Belarusian political emigration to strengthen the autocephalous movement. Comparative analysis of the activities of the Vicar’s bishops of the Russian Orthodox Church, activities of the North German Bishop Afanasy (Martos) and the Grossen-Hessen’s Archbishop Philofei (Narko) is carried out.
Social make-up of Vladimir branch of Imperial Orthodox Palestinian Society in the pre-revolutionary period
Authors: Kuznetsov Igor
Published: December 2023

The article is devoted to the study of the social composition of the Vladimir branch of the Imperial Orthodox Palestinian Society in the pre-revolutionary period. On the basis of published reports on the activities of the organization, the dynamics of changes in the number of its members was traced. The analysis showed that the number of members in the Vladimir branch of the Palestinian Society was close to the average for all reginal departments of the Society. The trends, revealed in the changes of the quantitative composition of the Vladimir department were similar to the other departments: rapid growth in the first three years has been followed by a steady decline since 1905.The study identifies the reasons for the decline in the number of members of the organization in the studied region. Attention is drawn to the fact that one of the reasons could be the death of Archbishop Sergius, who headed the Vladimir branch of the Palestinian Society since its creation, which led to the collapse of the system of personal ties that played a major role in attracting new members.Based on the collected data on the social status of the members of the Vladimir branch of the Palestinian Society, the social composition of the organization was analyzed, the representation of various social groups was revealed. The specifics of the social composition was determined by the fact that the Society was associated with religious activity, and those who were more closely connected with the Church, joined he Society first of all. Those groups were the clergy and merchants, whose representatives were often church wardens and actively participated in church charity. The other social groups are significantly less represented. Secular members made up the majority in the Vladimir branch of the Palestinian Society, but the percentage of the clergy gradually grew.It is noted that high membership fees and the selective invitation of new members determined the elite nature of the society. This, on the one hand, ensured a high status of membership, but, on the other hand, limited the possibilities of organizing the work of the society.
Clarifying the term “Chalcedonian Armenians”
Authors: Arutyunova-Fidanyan Viada
Published: December 2023

The ethnic self-consciousness of the Armenian ethnos, which passed the peak of ethnogenesis at the end of the first millennium BC, was ensured by the common origin, language and territory, common historical memory, continuity of state-political formations, cultural traditions and customs. Armenia is one of the oldest Christian states, and the Christianisation of the country in the early 4th century introduced a new cementing component into the Armenian identity. Wars with Mazdean Iran and later with the Muslim world, the struggle for fatherland and the struggle for faith cemented ethno-cultural and ethno-political identity. Armenia was one of the first countries to enter the Universal Church of the Christian East. Armenians participated in three Ecumenical Councils: the Council of Nicaea (325), the Council of Constantinople (381) and the Council of Ephesus (431), but did not attend the Fourth Council of Chalcedon (451) because of the war with Iran. The acts of the Council of Chalcedon, which reached Armenia much later, divided Armenians into two confessional directions — supporters and opponents of the Chalcedonian oros; the latter suspected in it hidden Nestorianism and did not recognise the supremacy of the Patriarch of Constantinople, while their opponents accused them of heresy. The emergence of Armenian writing in the early 5th century and the phenomenon of the «Golden Age» — the unprecedented rise of Armenian literature after the invention of the alphabet — determined for centuries the ethnic identity of Armenians, the unity of which was most universally and concretely reflected in the ethnic term «Armenian» (հայ, hay, ἀρμένιος). That is why the designation of the supporters of the Chalcedonian oros as Armenians-«Romaeans» and Armenians-«Georgians» did not find an adequate explanation for a long time. The term «Chalcedonian Armenians» was introduced in the early XX century by N. Y. Marr, as a designation of Armenians, called in the sources of XI–XV centuries «Romans» or «Ivirs», depending on their belonging to the Greek or Georgian Church. This hypothesis posed an important problem in Orientalism, caused continuous discussions and, accordingly, initiated further research. In recent decades, various aspects of the problem of the Chalcedonian Armenians (political, social, administrative, theological, polemical, historiographical) have attracted the attention of researchers; however, there is a range of issues that are unexplored or controversial. The term «Chalcedonite Armenians» proposed by N. Y. Marr instead of «Armenians-Romeans» and «Armenians-Ivirs» remained the most debatable issue for a long time. The aim of this paper is to clarify the content of the term «Chalcedonian Armenians» and, accordingly, the use of double ethnonyms in medieval sources, which served the emergence of this term in Modern times, i.e. to study the chronology and authorship of these sources.
“Apparently, their mother gave birth to them on Monday…” (on the earliest note to the oldest full manuscript of the Arabic Bible)
Authors: Frantsouzoff Serge
Published: December 2023

In the article the earliest note to the oldest complete copy of the Bible translated into Arabic, kept now in the Institute of Oriental Manuscripts of the RAS under shelf-mark D 226, t. 1–3, is edited with Russian translation and commentary. It contains the precise datings of two events: the entry of the Ottoman Sultan Selim I on the 27th of Radjab of AH 922 (the 26th of August of AD 1516) and the defeat of the rebel army of the Mamluk Djan-Birdi al-Ghazali by Ottoman troops on the 27th of Safar of AH 927 (the 5th of February of AD 1521). Both of them occurred on Tuesday which in the Middle East was considered as an unlucky day of the week by the Christians as well as by the Muslims. It is interesting to remark that the note is located just before the beginning of the Book of Genesis that tells about the days of Creation, from which the days of the week derive. Among the four political figures attested in the note the author succeeded in identifying three: besides two mentioned above this was Farhat-Bey who in spring of AD 1521 was appointed the governor of Tripoli where the customers of the oldest Arabic Bible probably lived. The manuscript was copied, while the events attested in the note remained relevant, i.e. shortly before or after them, just around AD 1521.
Textological features of the Chronicle of John of Nikiu
Authors: Gusarova Ekaterina
Published: December 2023

In the frame of the present research the text of the Chronicle of John of Nikiu’s translation in Geez is considered on the base of its textological features. This compilation was created in Egypt at the end of the 7th century AD by John, Bishop of the city of Nikiu, most probably in Greek. Later it was translated in Arabic and finally in the very beginning of the 17th century in Ge'ez. It reached our days exclusively in the Ethiopic revision. Nevertheless the test has conserved traces of the history of its existence. In particular it concerns foreign in relation to Ethiopia loans in lexis and some grammar constructions not intrinsic for traditional Ethiopian historiography. Such textological features of the translation from Arabic into Geez are of great interest for the scientists. They shed, albeit limited, light on the original Greek and then Arabic versions of the text of the Chronicle. In addition it forms an idea about the process of translating and personal and professional qualities of the translators in the Middle Ages in Egypt and Ethiopia.
Diagnostics and predictive maintenance of industrial electric motors

Published: December 2023

Automatic continuous or periodic control is the most promising method of diagnosing electric motors in productionnowadays. Itis aimed at predicting breakdowns and the remaining useful lifetimeof motors. However, research in this arearemains purely theoretical and eitherfocuses on very narrow problemsor providestoo superficial overview.Consequently,manual control devices orpartially automated devices are mainlyusedin practice[1]. In view of this, there is great interest in the development of a software method for predictive maintenance of electric motors. In this research recurrent neural networks with long short-term memory layers (LSTM-layers)are investigated due to their abilityto effectively model sequential data and learn complex dependencies [2].
