The art of novelist Afanasiy Fedorov
Authors: Burtsev A. A. , Burtseva M. A.
Published: October 2023

The article is devoted to the study of Afanasiy Fedorov's stories, which have a central place in the writer's heritage. His genre system includes various forms of short prose: from everyday stories to plot short stories, from small sketches, sketches of a character to psychological stories. The author's skill manifested itself primarily in the creation of a diverse artistic anthropology, consisting more of human rather than social types. Therefore, in his stories there is no tendentiousness and ideological bias characteristic of socialist realism. The characters' actions are psychologically motivated. The innovation of the Yakut writer was the creation of foreign heroes. In the poetics of his stories, the tradition of Russian literature was felt: like Anton Chekhov, he strove to show the complexity and significance of life phenomena through the simplest and most insignificant events of everyday life. On the whole, the logic of Afanasiy Fedorov's work was of an inductive nature: starting with small genres of prose, he gradually moved on to large epic forms.
Questions of studying Yakut fairy tales: a comparative analysis of stories about Granny Taаl-Taаl and Chaarchakhaan
Authors: Sivtseva-Maksimova P. V. , Fedorova T. I.
Published: October 2023

The article is devoted to the study of Yakut fairy tales. The works of I. A. Khudyakov, E. K. Pekarsky, G. U. Ergis, N. V. Emelyanov, modern researchers V. V. Illarionov, Yu. N. Dyakonova, N. A. Orosina and others are presented in the context of theoretical positions in the writings of Russian folklorists. The semantics of the study text is actualized as a process and result of live communication of carriers of cultural memory of ancestors, accompanied by targeted actions to rethink individual parts or episodes of its content. The preservation of interest in an ethnic literature in the modern world is facilitated by the availability of variants of fairy tales and images, but the early recordings of fairy tales are particularly significant. The aim of the work is to seek to substantiate various directions of analysis of folklore texts collected and systematized at the beginning of the 20th century; to identify static and dynamic episodes in stories, descriptions of portraits and functions of main characters. The methodological basis of the research are the works of V. Y. Propp, V. P. Anikin, S. Y. Neklyudov, Yakut ethnographers and folklorists A. E. Kulakovsky and G. V. Ksenophontov. In the process of work, source and textual methods of philology are used. The results consist in the analysis of the “Bibliography of the Yakut Fairy Tale” by Pekarsky (1912) and Ergis (1964 - 1967); in the characterization of the archival sources of features of the early folklore texts of Granny Taаl-Taаl and Chaarchakhaan. In this regard, one of the significant conclusions is the clarification of common places in their stories, and in the functions of the characters - analogies with mythological images and ancient rites.

Authors: Osipova G. S. , Vinokurova U. A.
Published: October 2023

The article is relevant due to the global changes in the country associated with COVID-19, which has had a huge impact on the society, in particular on young people, on their health, and quality of life. Purpose of the study: to analyze the self-assessment of health-related quality of life among students. To analyze the subjective self-assessment of health, official data from the 2022 Sample Population Health Survey conducted by the Federal State Statistics Service are presented. A sample observation of the health status of the population reveals that the majority of the population in the Russian Federation aged 20 to 39 years subjectively assess their health as “good”; however, 50% of the population aged 20 to 39 years have not undergone medical examination within last two years. The empirical study was conducted using a measuring tool – the WHO Quality of Life Questionnaire. The questionnaire measures an individual’s perception of health-related quality of life. The respondents were students studying at the North-Eastern Federal University and the Arctic State Institute of Culture and Arts. A study of self-assessment in six areas of health-related quality of life reveals that among students, “average” and “increased” indicators in all areas predominate. At the same time, boys have higher indicators of quality of life areas such as “level of independence” and “social relationships” than girls. The lowest indicator among all respondents is the “physical sphere”. In the general subjective self-assessment of the quality of life and health, for four global questions it was revealed that respondents assess their health and quality of life as “good”, which corresponds to the all-Russian trend.

Published: October 2023

On March 2, 2023, the Sakha Republic (Yakutia) saw the opening of a regional civil forum “Man of Labor: New Challenges and Opportunities”. As part of the discussion platform No. 1 “Decent work as the basis for human well-being”, a strategic session “Risks in the labor market of the Sakha Republic (Yakutia)” was held with the participation of ministries and departments, representatives of science and education, and the public. The work of the groups was concentrated on three tracks, according to which the moderators proposed to formulate the following blocks of the project presentation: the problem field, the benefit (effect) of solving the problem, and the packaging of the solution. The list of tracks of the strategic session covers the system of social and labor relations and creates risks in the labor market, caused mainly by internal factors. The sections formulated by the groups cover the influence of external factors as well. Based on the results of the strategic session, five groups developed recommendations to the State Assembly (Il Tumen) of the Sakha Republic (Yakutia), the Government of the Sakha Republic (Yakutia), the Ministry of Labor and Social Development of the Sakha Republic (Yakutia), the State Committee of the Sakha Republic (Yakutia) for employment, and the M. K. Ammosov North-Eastern Federal University. All the proposals are united by the desire for a balanced labor market and guaranteed employment, for which it is proposed to conduct a comprehensive career guidance work. The working groups are interested in the employment of graduates in jobs that provide a decent quality of life for young people, which will help reduce social tension, a favorable demographic and migration situation in the region. In addition, local communities are concerned about the increased participation of industrial enterprises in the socio-economic development of the territory of presence. The results of the strategic session in the form of practical recommendations to legislative and executive authorities, educational institutions emphasize the need for consolidated decisions of the state and society.
FINDS OF THE «SMOLENSK TYPE» IN THE NORTH-wEST OF THE RUSSIAN PLAIN: TO THE STUDY OF THE FORMATION OF MEDIEVAL RUSSIAN CULTURE
Authors: Михайлова Е.Р.
Published: October 2023

В статье рассматриваются находки металлических украшений, которые в российской археологической литературе обычно связываются с культурой смоленских длинных курганов и часто интерпретируются как «балтские», «балто-славянские» или «славянские». Часть таких предметов, найденных на Северо-Западе Русской равнины, действительно связана своим происхождением с культурой смоленских длинных курганов (серповидные височные кольца, круглая бляха с пуансонным орнаментом из Старой Ладоги). Однако большая часть «смоленских» предметов относится к набору металлических украшений, сложившемуся в последней четверти I тыс. и общему для лесной зоны Восточной Европы (перстнеобразные височные кольца с завитком наружу, головные венчики из рядов пронизей и обойм, трапециевидные привески с пуансонным орнаментом). Обращает на себя внимание отчетливый параллелизм типов украшений, употреблявшихся в Юго-Восточной Прибалтике и Волго-Окском бассейне.

The article discusses the metal ornaments, which in the Russian archaeological literature are usually associated with the culture of the Smolensk long mounds; they have often been interpreted as «Baltic», «Balto-Slavic» or «Slavic». Some of these items found in the North-West of the Russian Plain are indeed connected by their origin with the culture of the Smolensk long mounds (so called sickle-shaped temporal rings, a round plaque with a punched ornament from Staraya Ladoga). However, most of the «Smolensk type» items belong to the set of metal ornaments that developed in the last quarter of the 1st millennium AD and is common for the forest zone of Eastern Europe (ring-shaped temporal rings with a curl outside, headband from rows of metal tube beads and clips, trapezoidal pendants with a punched ornament). There is a clear parallelism of the types of jewelry used in the South-Eastern Baltic and the Volga-Oka basin.
Resolving metal binding properties within subunits of a multimeric enzyme Mnx by surface induced dissociation and native ion mobility mass spectrometry

Published: October 2023

Multi-subunit enzymes function as coordinated assemblies. Yet most enzymatic assays measure the summed output of all populations in solution and cannot easily differentiate contributions of individual subunits. Native mass spectrometry detects intact protein complexes in the gas phase. Surface induced dissociation further releases subunits from protein complexes while retaining compact conformations and bound ligands. Combined with ion mobility, the released subunits can then be carefully monitored for more in-depth structural analysis. Mnx is a unique bacterial multicopper oxidase complex that oxidizes Mn(II) to form MnO2 minerals, and is composed of three subunits: MnxG, a multicopper oxidase containing the active site, and two accessory proteins, MnxE and MnxF which also bind copper ions. Other known multicopper oxidases do not require accessory proteins, therefore the functions of MnxE and MnxF are not well understood. Here, we use native mass spectrometry with surface induced dissociation and ion mobility to characterize the metal binding properties of Mnx with two metals, catalytic Cu(II) and Mn(II) substrate. We demonstrate our assay can detect subtle structural changes within each subunit, which are presumably related to the allosteric mechanism. We also noticed that ionic strength and solution composition can impact metal binding and must be carefully investigated for such experiments.
Inhibitory Potential of Furanocoumarins Against Cyclin Dependent Kinase 4 Using Integrated Docking, MD and ONIOM Methods
Authors: Sarma Srutishree , Dowerah Dikshita , Basumatary Moumita , Phonglo Ambalika , Deka Ramesh Chandra
Published: October 2023

Cyclin Dependent Kinase 4 (CDK4) is vital in the process of cell-cycle and serves as a G1 phase checkpoint in cell division. Selective antagonists of CDK4 which are in use as clinical chemotherapeutics cause various side-effects in patients. Furanocoumarins induce anti-cancerous effects in a range of human tumours. Therefore, targeting these compounds against CDK4 is anticipated to enhance therapeutic effectiveness. This work intended to explore CDK4 inhibitory potential of 50 furanocoumarin molecules, using a comprehensive approach that integrates the processes of docking, drug likeness, pharmacokinetic analysis, molecular dynamics simulations and ONIOM (Our own N-layered Integrated molecular Orbital and Molecular mechanics) methods. The top five best docked compounds obtained from docking studies were screened for subsequent analysis. The molecules displayed good pharmacokinetic properties and no toxicity. Epoxybergamottin, dihydroxybergamottin and notoperol were found to inhabit the ATP-binding zone of CDK4 with substantial stability and negative binding free energy forming hydrogen bonds with key catalytic residues of the protein. Notopterol exhibiting the highest binding energy was subjected to ONIOM calculations wherein the hydrogen bonding interactions were retained with significant negative interaction energy. Hence, through these series of computerised methods, notopterol was screened as a potent CDK4 inhibitor, and can act as a starting point in successive processes of drug design.
Detection, quantification, and isomer differentiation of per- and polyfluoroalkyl substances (PFAS) using MALDI-TOF with trapped ion mobility
Authors: Reynolds Aidan , Smith Abby , Qiu Tian (Autumn)
Published: October 2023

Per- and polyfluoroalkyl substances (PFAS) are a class of organic compounds that have attracted global attention for their persistence in the environment, exposure to biological organisms, and their adverse health effects. There is an urgent need to develop analytical methodologies for characterization of PFAS in various sample matrices. In the present study, a list of legacy and alternative perfluorocarboxylic acids (PFCAs) and perfluorosulfonic acids (PFSAs) was analyzed by matrix-assisted laser/desorption ionization time-of-flight mass spectrometry coupled with trapped ion mobility spectrometry (MALDI-TIMS-TOF). Parts per billion (ppb) quantitation and detection was achieved for PFCAs whereas PFSAs yielded parts per trillion (ppt) quantitation and detection. Multi-day calibration curves were assessed by linear regression and calculation of limits of detection and quantification. Using TIMS, we also successfully separated three perfluorooctanesulfonic acid (PFOS) structure isomers in the gas phase. Our results demonstrated the new development of utilizing MALDI-TOF-MS coupled with TIMS for fast, quantitative, and sensitive analysis of PFAS, paving ways to future high-throughput and in situ analysis of PFAS such as MS imaging applications.
Distilling Coarse-Grained Representations of Molecular Electronic Structure with Continuously Gated Message Passing
Authors: Maier Charlie , Wang Chun-I , Jackson Nicholas
Published: October 2023

Bottom-up methods for coarse-grained (CG) molecular modeling are critically needed to establish rigorous links between atomistic reference data and reduced molecular representations. For a target molecule, the ideal reduced CG representation is a function of both the conformational ensemble of the system and the target physical observable(s) to be reproduced at the CG resolution. However, there is an absence of algorithms for selecting CG representations of molecules from which complex properties, including molecular electronic structure, can be accurately modeled. We introduce continuously gated message passing (CGMP), a graph neural network (GNN) method for atomically decomposing molecular electronic structure sampled over conformational ensembles. CGMP integrates 3D-invariant GNNs and a novel gated message passing system to continuously reduce the atomic degrees of freedom accessible for electronic predictions, resulting in a one-shot importance ranking of atoms contributing to a target molecular property. Moreover, CGMP provides the first approach by which to quantify the degeneracy of ``good" CG representations conditioned on specific prediction targets, facilitating the development of more transferable CG representations. We further show how CGMP can be used to highlight multiatom correlations, illuminating a path to developing CG electronic Hamiltonians in terms of interpretable collective variables for arbitrarily complex molecules.
Defects in 3D Printing and Strategies to Enhance Quality of FFF Additive Manufacturing. A Review
Authors: Erokhin Kirill , Naumov Sergei , Ananikov Valentine
Published: October 2023

Additive manufacturing technologies (or 3D printing) have emerged as potent tools in the creation of a diverse array of objects, promising a paradigm shift in production methodologies across industries. However, the benefits of these technologies can be diminished by the use of suboptimal parameters or inferior materials, leading to defects that significantly degrade the quality and functionality of the resulting products. An incomplete understanding of defect formation keeps under the formulation of effective preventative strategies. In light of this, our review provides a comprehensive exploration of defects that arise during the Fused Filament Fabrication (FFF)—one of the most prevalent 3D printing methods. The defects are systematically classified according to several key characteristics, including size, type, mode of occurrence, and location. Each common defect is extensively discussed, detailing its external manifestation, root causes, the impact on the properties of printed parts, and potential preventative measures. Our findings unveil the complex interplay of material properties, printing parameters, and cooling dynamics in the defect formation process. This classification holds significant practical relevance, providing a solid foundation for the development of strategies for defect minimization and quality improvement in 3D printed products. It offers valuable insights for a broad audience, including researchers exploring additive manufacturing technologies, 3D printing engineers, 3D printer operators, and quality assurance (QA) engineers involved in production quality control. Furthermore, our review delineates the path for future research in this domain. There is a crucial need for the development of advanced machine learning and artificial intelligence models that can predict defect formation based on given printing parameters and material properties. Future investigations should also focus on the discovery of novel materials and refining of printing parameters to achieve superior quality of FFF 3D printed products. This review serves as a cornerstone for these future advancements, promoting a deeper understanding of defect formation and prevention in additive manufacturing.

Published: October 2023

Recycling lithium-ion batteries (LIBs) can supplement existing supplies of critical materials and improve the environmental sustainability of LIB supply chains. In this work, environmental impacts (greenhouse gas emissions, water consumption, energy consumption) of industrial-scale production of battery-grade cathode materials from used LIBs are compared to the environmental impacts of conventional mining supply chains. Refining mixed-stream LIBs into battery-grade materials reduces these environmental impacts by at least 59%. Recycling batteries to mixed metal products instead of discrete salts further reduces environmental impacts. Electricity consumption is identified as the principal contributor to all LIB recycling environmental impacts, and different electricity sources can change greenhouse gas emissions up to eight times. Supply chain steps that precede refinement (material extraction and transport) contribute marginally to the environmental impacts of circular LIB supply chains (<5%), but are more significant in conventional supply chains (31%). This analysis disaggregates conventional and circular steps based on material extraction, transport, and industrial refinement operations; provides important insights for advancing sustainable LIB supply chains; and informs optimization of industrial-scale environmental impacts for emerging battery recycling efforts.
Quantum Magnifying Glass for Chemistry at the Nanoscale
Authors: Csizi Katja-Sophia , Steiner Miguel , Reiher Markus
Published: October 2023

Nanoscopic systems exhibit diverse molecular substructures by which they facilitate spe- cific functions. Theoretical models of them, which aim at describing, understanding, and predicting these capabilities, are difficult to build. Viable quantum-classical hybrid mod- els come with specific challenges regarding atomistic structure construction and quantum region selection. Moreover, if their dynamics are mapped onto a state-to-state mecha- nism such as a chemical reaction network, its exhaustive exploration will be impossible due to the combinatorial explosion of the reaction space. Here, we introduce a quantum magnifying glass that allows one to interactively manipulate nanoscale structures at the quantum level. The quantum magnifying glass seamlessly combines autonomous model parametrization, ultra-fast quantum mechanical calculations, and automated reaction ex- ploration. It represents a unique approach to investigate complex reaction sequences in a physically consistent manner with unprecedented effortlessness in real time. We demon- strate these features for reactions in bio-macromolecules and metal-organic frameworks, diverse systems that highlight general applicability.

Authors: Jairao Deshpande Sumit , Abdul Qayum Syed , Abhishek G , Ruhi Zainab
Published: October 2023

Inadequate alveolar ridge width often poses difficulty in implant placement. Such ridges require a combination of techniques in placing implants. One such technique is the ridge split technique which helps the expansion of the ridge with or without greenstick fracture of cortical plates. Before placing implants the width of the alveolar ridge can be effectively restored utilising the modified ridge splitting approach employing autologous bone grafts. This case report describes the ridge splitting and placement of a dental implant in the left maxillary central region followed by guided bone regeneration. Ridge expansion was done in relation to 21 and osteotomy was prepared to the desired depth. After proper treatment planning implant measuring 3.5 mm in diameter and 11.5 mm in length was placed. Four months later final cementation was done with PFM crown. The ridge split technique with the immediate implant placement resulted in minimal resorption of alveolar bone along with maximum expansion of the bone. The sequential surgical and restorative techniques were combined into one successful protocol whose steps are well elaborated in this case report.

Authors: Todkar Vaishali , Habbu Prasanna , Kulkarni Venkatrao , Madagundi Smita
Published: October 2023

A progressive loss of functional and structural integrity of the central nervous system leads to neurodegenerative diseases. Neurotoxicity refers to direct or indirect effect of chemicals that disrupt the nervous system. Human beings are grieving from nervous related ailments due increase in the population and aging. Because of the limited capacity of neurons to regenerate there is still no trusted and consistent therapeutic approach available to treat neurodegenerative diseases. Natural compounds have been widely studied as potential neuroprotective agents because of their characteristics of multiple targets and low cytotoxicity. Endophytes could be any organism either bacteria fungi actinomycetes or mycoplasm which reside inside the tissues of plants showing mutualistic relationships without infecting any of the plant cells. Variety of novel secondary metabolites and known analogues of plant metabolites are produced by endophytic microbes. Structurally distinctive and therapeutically active natural products such as flavonoids phenolic acids polyketides terpenoids benzopyranones quinines steroids alkaloids etc. are obtained from endophytes for their potential use in medicine agriculture or industry. Considerable literature is also available on chemically diversified compounds isolated from endophytic fractions possessing neuroprotective activity. The present review emphasizes on promising neuroprotective metabolites isolated from endophytic microbes inhabited in medicinal plants.
Method for analyzing the vulnerability of water resources in an unstable environment based on the entropy approach
Authors: Bezsonnyi V. L.
Published: October 2023

Purpose. The synthesis of the method of analyzing the vulnerability of water resources based on the entropy of the connection based on the determination of the factors of the water system, considering the relationship between the anthropogenic socio-economic system and the "man-environment" system and the analysis of the transformation processes of the water system in a changing environment.

Results. The mechanism of vulnerability of water resources in a changing environment is analyzed. The structure of the vulnerability of water resources is established based on sensitivity, natural resistance and artificial adaptation by analyzing the four states of the water system: the sensitive state, the impaired state, the recovery state and the equilibrium state, and accompanying transformation processes. A method for analyzing the vulnerability of water resources based on contact entropy is proposed, which extends the concept of contact entropy. The degree of vulnerability of water resources to the changing environment can be divided into five levels with 11 indices: low (I), insignificant (II), moderate (III), high (IV) and extreme (V). Calculation of the contact entropy shows an approximate value of the contact entropy S with a range of (–1.314; 1.314). This interval is divided into five parts: [0.877; 1.314), [0.292; 0.877), [−0.292; 0.292), [−0.877; −0.292), (−1.314; − 0.877), indicating low (I), insignificant (II), moderate (III), high (IV) and excessive (V) degrees of vulnerability of water resources, respectively.

Conclusions. The state of a water system usually changes from impaired to restored due to natural factors, followed by a transition from a state of restoration to a state of equilibrium mainly due to artificial factors. The first is defined as natural resilience, and the second as artificial adaptation. The results of this mechanism offer a necessary understanding of the vulnerability of water resources in a changing environment, the mechanism of the transformation process between the four states is the focus of further research.

Methods. Observation, systematic approach, analysis and synthesis, generalization, system-structural, comparative-geographical, cartographic, mathematical

Results. The peculiarities of the geospatial distribution of forest areas on the territory of the state-owned forestry enterprise “Berehiv forestry”, their age structure, species composition, and distribution within forestry have been analyzed. Based on the primary materials, a map of forest categories in terms of forestry has been constructed and analyzed: “The categories of forest of the state-owned forestry enterprise “Berehiv forestry” in the context of forestry”. It has been defined that the forests perform the following functions: nature protecting, recreational and health-improving, and protective on the territory of the forestry. Despite the fact that the level of forest cover in the region is low and the forest areas are fragmented the production forests dominate here. Spatial analysis of the age structure and species composition in the forests of the State Enterprise "Berehiv Forest Farm" has been carried out. It has been found out that hardwood plantations dominate among the species composition of forest tracts. The leading place belongs to oak and beech stands. Conifers did not become widespread due to the peculiarities of local growth conditions. Tiny areas of low-value soft-leaved stands show the active and successful work of foresters. It has been clarified that the age structure of forests is dominated by medieval plantations. They are located mainly in the central and eastern parts of the territory that has been under the research. Mature and overmature stands dominate in the northern part.

Conclusions. It has been identified that, the area, which has been under the research is the least forested in Thanscarpathia region. The production forests are located in the most forested central and northern parts of the forestry, while the other categorizes dominate in the eastern and western outskirts. The area of Berehiv forestry requires a set of measures to be done to grow forests on infertile acidic soils and optimization of the age structure of existing forest areas.

Scenario analysis loss of heat removal from the spent fuel pool on nuclear power plant
Authors: Hakobyan M. T. , Ksenofontov A. I. , Sargsyan S. A.
Published: October 2023

The spent nuclear fuel storage system is designed to store and cool spent fuel for several years taking into account scheduled reloads and unloading of the entire core accumulated after use in a nuclear reactor. It consists of special pools or containers where spent fuel is placed for temporary storage before final treatment or disposal. These systems provide safe and efficient storage of spent fuel to prevent radioactive material from leaking into the environment and minimize risks to human health and the natural environment. The events that occurred during the Fukushima nuclear disaster on March 11, 2011, underscored the importance of safe storage of spent fuel in the spent fuel storage pool. Storage safety has therefore become a key aspect in this area. This article describes the heat sink loss calculations for the analytical substantiation of the emergency response instructions for the shutdown state of the Armenian NPP power unit No.2 using the RELAP5/Mod3.2 computer code. The initiating event in the event of loss of heat removal from the spent fuel pool is considered. The analysis of nuclear safety in the course of the development of a beyond design basis accident with a long NPP blackout was carried out in relation to the spent fuel pool of a power unit with a reactor plant WWER-440 (project V-270). The radiation consequences are estimated. The article provides calculations of the following accidents to determine the necessary actions of the operator: loss of heat removal from the spent fuel pool without operator action and loss of heat removal from the spent fuel pool from the organizations of subsequent make-up of the spent fuel pool with a boron cleaning pump (2NBO-2). The calculations are based on boundary and initial conditions corresponding to the assumptions of the «better estimate».
Vibroconverter mathematical model based on the levitation effect
Authors: Shilin A. N. , Makartichyan S. V. , Barashkov I. S.
Published: October 2023

Modern requirements for the safe operation of nuclear power plants dictate the need to introduce systems for early reactor plants state diagnosis. Vibrations have always been a threat to the safe nuclear power plants operation, therefore, solving the issues of improving the nuclear power plants vibronoise diagnostics accuracy, especially in the field of ultra-low frequencies, is an urgent task. The most promising way to solve the problem of flexible guides in electromechanical vibration transducers is the levitation effect, which makes it possible to completely eliminate mechanical contact and, accordingly, reduce the sensitivity threshold of the transducer. The article presents an analysis of existing vibration transducers and offers analogue and digital mathematical models of the magnetic levitation system, taking into account the influence of the electromagnetic force nonlinearity. The characteristics of such a nonlinear system are studied using the method of harmonic linearization, which makes it possible to obtain an equivalent linear system. At the same time, the third order terms of the electromagnetic force expansion in the Taylor series are taken into account, which made it possible to obtain a more accurate analogue the vibration transducer model. For the developed vibration transducer digital model, using the z-form method, a system function and the corresponding difference equation were obtained. Expressions and graphs of transient, pulse and frequency characteristics are derived for both analogue and digital vibration converter models, which allow us to conclude about the accuracy and adequacy of the developed digital model. Using obtained vibration transducer digital models will make it easier to model its operation and reasonably select the vibration transducer initial parameters.
Smartwatch Technology's Diagnostic Use in Atrial Fibrillation Detection – A Literature Review
Authors: Mikhail Joshua A. , Tadros Daniel , Shehata Rafael
Published: October 2023

Introduction: An ECG is the gold standard for detecting various cardiology pathologies including AF. Current ambulatory heart rhythm monitoring technology include Holter monitoring and various implantable event monitors, which provide continuous monitoring but are invasive, uncomfortable and may lack in detecting intermittent arrhythmias, due to their periodic exploratory monitoring strategy. Methods: A systematic search was conducted using the following databases: Cochrane Library, Embase, PubMed, and Google Scholar. The search was conducted using the keywords "atrial fibrillation," "smartwatch," "ECG," "stroke," and "PPG”. Relevant sources between 2018 and 2023 were chosen, and data was analysed to establish clinical utility in early diagnosis of AF. Results: Two studies assessing the diagnostic efficacy of smartwatch technology, two studies investigating the usability of new technology and one study assessing cost-effectiveness were included in our review. The diagnostic efficacy of smartwatches ranges from 93.5-98.25% accurate, 92.45-97.3% sensitive and 88.6-100% specific, with PPV ranging from 91.6-100%, and NPV ranging from 93.85-96.83%. Targeted audiences of AF detection includes a larger proportion of older adults with possible declined technological and/or cognitive function, and may find difficulty using current smartwatch technology. With a simplified user interface, novel software like Pulsewatch promotes user accessibility in smartwatch technology, making AF detection simple to identify, particularly in elderly people. 90 patients used the Pulsewatch system, and more than half reported having a positive experience with the system; only 13% considered it excessively stressful. Discussion: Due to the low 65+ age group representation (6.6%) in studies like Fitbit, Huawei, and Apple heart studies, they overlook potential bias in older adults' adherence to pAF monitoring. Pulsewatch addresses this issue. Smartwatches, being user-friendly and cost-effective, offer real-time, reasonably accurate prospective data for patients. However, further research is required to gauge their clinical utility in early AF detection, diagnostic effectiveness during daily activities, and the heterogeneity of smartwatch devices remains to be fully explored. Conclusion: User-friendly PPG-based smartwatch technology is a medically accurate alternative to standard AF detection techniques that may speed up the diagnosis and treatment of AF, lowering stroke and cardiovascular disease-related morbidity and mortality as well as AF-related healthcare costs.
Second Star To The Right: Witi Ihimaera as a Queer Forefather of New Zealand Literature
Authors:   , Smith Eden
Published: October 2023

For the past forty years queer New Zealand criticism has been contending with critics who reject the kind of classification that the category queer suggests. Even when the texts examined feature queer themes, or are written by queer authors, there is sometimes a reluctance to label them as a distinctly queer literature. To confuse matters further, it is often our most pivotal writers who have utilised what we might view as queer modes of storytelling, serving to enmesh and complicate this relationship between works that are canonised and those that are queer. Witi Ihimaera is an author whose works, at times, resist queer categorisation: is he a New Zealand author? A Māori author? A queer author? How do these identities interact with each other? This thesis will first seek to understand how Ihimaera’s queer identity is represented within the New Zealand canon of literary criticism and will use close readings of his archival material to document how his literary gay identity has been shaped. Secondly, I read Ihimaera’s Nights in the Gardens of Spain (1995) against the backdrop of its drafts. This thesis studies how the queer content in Nights emerges and evolves. From there I consider Ihimaera’s literary gay identity in relation to his surrounding novels and the spiral of his other overlapping identities and loyalties. The deconstruction of Ihimaera’s identities will help us firmly place him as a gay New Zealand literary forefather.

Good service can be seen from the effective communication that exists between service providers and guests. A waiter becomes a very important factor in the process of communication and service. One area that is the centre of service is in the area of The Oryza Restaurant. However, it was found that there was a communication gap that led to miscommunication and erroneous information capture. Often communication gaps arise when waiters deal with foreign tourists. One of the factors causing this gap is the language skills of the waiter. This study aimed to analyze the communication gap to measure the effectiveness of service communication at The Oryza Restaurant and the quality of a waiter as a communicator. This study used a descriptive qualitative method with data collection through interviews and observation as well as document study support. Data processing was carried out using coding techniques and data triangulation from interviews and observations. The results of the study showed that there is a gap in communication due to the language factor which causes the ineffectiveness of two indicators in effective communication, namely Content and Clarity. Then it was also found that the waiter as a communicator is capable of ethos and attitude in serving guests. With this research, it is hoped that there will be a periodic evaluation and control process for each service worker to get quality waiters who are qualified to serve and comply with company service standards.
