Scale and Correlation in Multiscale Geographically Weighted Regression (MGWR)
Authors: Oshan Taylor M. , Kang Wei
Published: November 2024

Multiscale Geographically Weighted Regression (MGWR) is a relatively recent innovation and addition to the family of spatial regression models capable of investigating process heterogeneity. Compared with its predecessor, Geographically Weighted Regression (GWR), MGWR relaxes the assumption of a uniform spatial scale across all modeled processes. That is, MGWR allows for the possibility that some processes vary locally while others vary regionally or not at all. As a result, it provides more accurate parameter estimates. However, this relationship between scale and the correlation within and across geographically weighted regressors (i.e., spatial autocorrelation and multicollinearity) has yet to be formally investigated. This paper sheds light on this issue via two sets of controlled simulation experiments. The results suggest that both types of correlations have a negligible effect on MGWR performance until they become very strong, and their impacts are cumulative. Overall, MGWR is better at alleviating any potential local multicollinearity issues than GWR due to the varying scales estimated for different parameter surfaces. Two additional insights were obtained regarding scale. First, high levels of spatial autocorrelation may potentially contribute towards the underestimation of scale for certain processes, typically those with the lowest level of spatial heterogeneity (including the intercept), potentially falsely identifying local effects. Second, high levels of collinearity may contribute to the misidentification of anticipated scales. In some cases, when the true process is spatially varying, collinearity may lead the bandwidth to be overestimated, which can help mitigate issues associated with high collinearity but may also lead to difficulty identifying local effects. In other cases, when the true process is constant, collinearity may lead the bandwidth to be underestimated but is not problematic for accurately estimating coefficients unless collinearity becomes high. As a result, it is suggested that the optimal bandwidths estimated from MGWR be interpreted with some caution for the additional factors that may influence them. These results have important implications for empirical applications of MGWR.

Authors: Baston George , Qian Jing
Published: November 2024

Advancements in low-cost hyperspectral imaging for low-light environments represent a significant leap forward in imaging technology, blending spectroscopy with advanced imaging capabilities to provide detailed analyses of material composition and characteristics. Traditionally, hyperspectral imaging has been an expensive and complex field, primarily utilized in remote sensing, environmental monitoring, and medical imaging. However, recent innovations have focused on reducing costs and enhancing accessibility, making it feasible for a broader range of applications, including portable devices like smartphones, UAVs, and DIY systems. Significant advancements include the development of on-chip computational hyperspectral imaging frameworks, which integrate broadband filtering materials directly onto imaging sensors, and hyperspectral lightfield cameras that combine hyperspectral and 3D analysis capabilities. These technologies improve light throughput and spatial-temporal resolution, thus enabling high-quality imaging even with lower-cost components. Quanta image sensors (QIS) have further enhanced low-light performance by utilizing high-speed readout and photon-number-resolving capabilities, proving particularly useful in medical diagnostics and environmental monitoring. Applications of these advancements are vast and varied. In agriculture, hyperspectral imaging facilitates precision farming by detecting crop stress and optimizing yield. In environmental monitoring, it allows for the detailed observation of vegetation health and water quality. The technology also plays a critical role in food quality control and biomedical imaging, where it provides non-destructive methods to assess food safety and diagnose diseases at an early stage. Despite these promising developments, several challenges remain. The complexity and cost of hyperspectral systems, along with the need for advanced data processing and storage capabilities, are significant hurdles. Issues such as spectral and spatial resolution, noise sensitivity, and data management continue to require sophisticated solutions and further research. Nonetheless, the ongoing advancements in sensor design, algorithm development, and machine learning integration hold promise for overcoming these challenges and expanding the scope and utility of hyperspectral imaging in various fields.
A Higgs Cosmology That Agrees a Lot, and Disagrees More with Current Physics
Authors: Zhu Wei-Jie
Published: November 2024

arranged in the non-conventional, yet gauge-theory-similar methodology, a Higgs cosmology is investigated to proposing a standard solution to Higgs boson mass calculation (𝑀𝐻−𝑠𝑠). The calculation involves a ‘best choice’ seeing spontaneous symmetry breaking (SSB) of two critical factors (𝐷𝑡𝑡𝑙𝑠𝑟𝑜𝑚 and 𝑅(01)−25𝑝) that results in gravitation quantization is automatically embedded. The gravitation quantization covers ‘main’ quantization and ‘accompanying’ quantization, firstly appearing in the ‘original’ version, then in the ‘mirror’ version, of 'transformation’(see 8)). The ‘transformation’ demonstrates a reversed sequence of relative strengths (RS) that requires an event of Relative Strength Identity Shift (RSIS) inevitable to satisfy the total ≈ 1038.5 gap and hence, RSIS must be the root cause behind the hierarchy problem (footnote 16 and table 3 of the 5th of 9)). The ‘transformation’ also plays a significant role in the Universe’s expansion history and vetoes the popular inflation theory resolutely, for the latter engages only gravitation without true quantization that turns its solution to be a baseless delusion short of question of a behind reason for the problems it aims to address (see 10) and 8)). The ‘best choice’ itself directly implies the structural Universe and thanks to the transforming factor (𝑅(01)−25𝑝) working on its shift ‘after flow’, the so-called dark energy and dark matter known to current physics come into reality (see 11)). Investigating further on the basis of the ‘best choice’ that’s built on ratio 'baryon' to photon (𝜂𝑠𝑛 or 𝜂𝑠𝑛−𝑝), it is shown it is not the commonly recognized 𝜂, but the derived PAR ratio (𝜂𝑝𝑎𝑟) that expresses a genuine asymmetry between matter and antimatter, and sets a big difference from 𝜂 in ≈ 103−5 scale (see 12)). A sophisticated table 2 is made to explore the many details of the proposed Higgs cosmology...
Lorentz covariant formulation of the Navier-Stokes equations by Laplace-Beltrami differential operators
Authors: Longfellow Alan
Published: November 2024

Though the Navier-Stokes equations of fluid mechanics have proven useful in multiple dis- ciplines of physics and engineering, they are incapable of describing flows where relativistic effects are present due to their Galilean invariance. For a Navier-Stokes equation set to be mathematically capable of modeling relativistic effects on the temporal evolution of its velocity field in curved space, all of its differential operators must instead exhibit Lorentz covariance. Many attempts have been made at formulating a theory of viscous relativistic fluid mechanics, but none have emphasized Lorentz covariance. This work therefore seeks to construct a Lorentz covariant version of the Navier-Stokes model of fluid motion so as to support relativistic vis- cous flows. To accomplish this task, the Galilean invariant gradient, divergence, Laplacian, and material derivative operators present in the Navier-Stokes equations are reconstructed in terms of the covariant derivative operator for curved space. The velocity and external force fields are also modeled as four-vectors to capture the effects of time dilation and length contraction on turbulent flow patterns, which helps to properly account for the relativistic scaling and skewing of important observed phenomena such as temporal mixing scales and Komolgorov microscales.
Pregnancy complications during the COVID-19 pandemic: A case for understanding genetic conflict in pregnancy
Authors: Ayers Jessica Daphne , Cardwell Madelyn , Park Jonathan
Published: November 2024

Early in the COVID-19 pandemic, many pregnancy complications experienced unexplained changes in frequency worldwide. Despite the lack of consensus in the medical community, we propose that behavioral changes required during pandemic lockdowns influenced the manifestation of underlying genetic conflict and contributed to the observed changes in the frequency of pregnancy complications. A better understanding of the genetic conflict that underlies these complications can offer researchers and practitioners potential explanations for these changes as well as insights into the treatment of these complications. Here, we provide an overview of genetic conflict theory, summarize the changes in pregnancy complications during the COVID-19 pandemic, and provide insight into how the public health responses to the COVID-19 pandemic potentially influenced the genetic conflict that underlies these pregnancy complications.
Diabetes Prediction Using Logistic Regression Optimized with Newton-Raphson: A Non-Invasive Approach
Authors: Mehdaoui Manal
Published: November 2024

Diabetes, a metabolic disorder characterized by insufficient insulin production or utilization, poses significant health risks. Traditional diagnostic methods are often invasive and costly, limiting their accessibility. In this paper, we propose a non-invasive approach to diabetes prediction using logistic regression, a supervised machine learning algorithm, optimized with the Newton-Raphson method. This algorithm is used for classification tasks, modeling the relationship between a binary outcome (diabetes status) and a set of predictor variables. The model utilizes a subset of features from the Pima Indians Diabetes Database, including 'Pregnancies', 'Glucose', 'BloodPressure', 'SkinThickness', 'Insulin', 'BMI', 'DiabetesPedigreeFunction', and 'Age'. The Newton-Raphson algorithm iteratively updates model parameters to maximize the likelihood estimation, ensuring efficient convergence. Our results show a pseudo-R-squared value of 0.7536, explaining 75.36% of the variability in diabetes status. The model achieved an overall accuracy of 75%, demonstrating its effectiveness in predicting diabetes status. Despite this, the model encountered 60 false positives and 132 false negatives, suggesting areas for improvement. This approach offers an effective, cost-efficient alternative for early diabetes detection, providing valuable insights into the factors influencing diabetes risk.

Published: November 2024

Agro-morphological characterization and genetic diversity analysis is pivotal to identify elite genes for further improvement of germplasms. In Spring 2022, 52 spring (Chaite) rice accessions were evaluated for 12 agro-morphological traits in alpha lattice design with two replications under irrigated condition at agronomic farm of Gauradaha Agriculture Campus, Jhapa, Nepal. Results showed the existence of considerable amount of diversity in rice accessions. The first three principal components (PC1, PC2 and PC3) with eigen value greater than one were identified with a total cumulative variation of 95.04% showing that the accessions could be grouped at least into three main varied classes. The accessions were grouped into 5 clusters.  The accessions falling in cluster II had the maximum grain yield. The accessions namely Hardinath-1 (4.87 t/ha), IR17A3019 (4.37 t/ha), IR17A2949 (4.12 t/ha) were found to have high yielding accessions. High genetic variability among the rice accessions was found for the traits viz., grain yield, thousand grain weight, length breadth ratio, days to flowering, days to maturity, panicle length, effective tiller per hill and have pertinency in future spring rice breeding programs for the selecting potential parent lines based on those traits.

Authors: Akande Alex Adekoya , Akindele Aarinola Abosede , Owolabi Abayomi Justine
Published: November 2024

The study investigated the Ikorodu community's energy poverty status by adopting the Multidimensional Energy Poverty Index to assess each sub-community, as it centers on energy poverty. The study used both quantitative and qualitative assessments of data obtained from primary and secondary sources. The primary data was sourced from a questionnaire administered to households while secondary data was sourced mostly from the National Bureau of Statistics’ Nigeria Living Standard Survey (NLSS) dataset. Additional secondary data was obtained from the Lagos State socio-economic data survey which included the Ikorodu subset. The result showed that about half (42%) of the community was energy-poor while more than half (58%) were energy-non-poor. The study revealed energy poverty has a huge impact on the economic development of the studied communities, as there was a positive and significant correlation between energy poverty and educational, health, and economic activities. More specifically, energy poverty reduces social inclusion, diminishes the education level of the residents of the communities, lessens the quality of life and healthcare, and discourages business activities and the establishment of new businesses in the area. Given these findings, the study emphasizes the need for government intervention and public awareness to increase access to electricity through renewable energy sources. Additionally, it recommends promoting- clean and cost-effective energy alternatives to address the pressing issue of energy poverty within the community.
Analiza porównawcza opisów przemocy w polskich przekładach powieści Rebecca Daphne du Maurier (1938)
Authors: Jaworska-Biskup Katarzyna
Published: November 2024

Daphne du Maurier to znana na całym świecie autorka powieści określanych mianem gothic fiction i gothic romance. W swej bogatej twórczości, która stała się inspiracją dla wielu reżyserów filmowych, w tym mistrza grozy Alfreda Hitchcocka, pisarka kreuje barwne obrazy nasycone agresją i grozą. Bohaterowie du Maurier doświadczają wszelakiego rodzaju przemocy, zarówno fizycznej i psychicznej, jak również seksualnej. Sceny agresji budują napięcie, stanowią punkt kulminacyjny, obnażają stany psychiczne bohaterów. Obrazom walki i obrony towarzyszą momenty strachu, przerażenia i paniki, które du Maurier szczegółowo opisuje na kartach swych książek. Zadaniem tłumacza jest odwzorowanie ładunku emocjonalnego zawartego w oryginale, co — jak pokazuje zgromadzony materiał badawczy — nie zawsze jest przedsięwzięciem udanym. Artykuł stanowi próbę analizy wybranych scen przemocy w powieści Rebecca du Maurier i dwóch polskich przekładach. Badaniu przyświeca chęć odpowiedzi na następujące pytania: a) za pomocą jakich środków językowych i stylistycznych kreowana jest przemoc w oryginale i przekładzie? b) na ile obrazy przemocy stworzone przez polskich tłumaczy są spójne z obrazami pióra du Maurier? c) z jakimi trudnościami zmaga się tłumacz twórczości du Maurier, a szerzej gatunku gothic literature?
Points of Connection and Separation of the Text and the Play on the Example of Wilde’s and Zadar’s Star-Child
Authors: Tretinjak Igor
Published: November 2024

Understanding adaptation as a two-way process in which the original medium and the medium of adaptation interact with each other, the paper analyzes the relationship between the fairy tale The Star-Child by Oscar Wilde and the puppet play The Star-Child by the Zadar Puppet Theater, directed and adapted by Milena Dundov. The two works are connected by a series of common elements that they approach and use in some places similarly, but more often differently. The key point of difference, in addition to the differences in the media, is the temporal, spatial and especially social context in which the fairy tale and the puppet show were created. The paper analyzes the similarities and, particularly, the differences between the two works, and attempts to notice the second part of the two-way influence — the adaptation’s influence on the source.

STRATEGY FOR IMPROVING THE EFFICIENCY OF UTILIZATION OF PIG FARM MANURE EFFLUENTS USING DECANTER CENTRIFUGES
Authors: Khamitov Eduard
Published: November 2024

The article is devoted to increasing the efficiency of manure
disposal and reducing operating costs through the use
of solid-wall decanter centrifuges. The profitability of animal
husbandry, like any production, is determined by the efficiency
of each technological stage at the enterprise. Feeding, veterinary
control, maintenance, waste disposal, all these processes
are important and interrelated. It is important to establish and
use the most modern processes and approaches. The article
shows the importance of the waste disposal stage, from a
technological, financial, and legal point of view. This article discusses
the process of mechanical separation of manure runoff
into solid and liquid fractions. The efficiency of this technological
process has a great impact on the environmental friendliness
of production and on the smooth operation of the entire
enterprise. From a technical point of view, the effectiveness of
a technical process is always specific parameters and indicators.
In this case, the concentration of the solid phase in the
filtrate after separation and the moisture content of the solid
phase after dehydration are considered as the main ones. According
to these indicators, one can draw a conclusion about
the technological efficiency of this or that equipment. The total
cost of ownership of equipment is determined not only by the
initial investment, but also by the associated operating costs,
such as service and spare parts. The author considers the
main modern technical methods of separation, what physical
principles they are based on, what advantages and disadvantages
they have. It also considers what technical difficulties
may arise when choosing one or another option. The author
proposes an algorithm for selecting equipment, taking into account
the characteristics of this segment of the manufacturer’s
market. Practical solutions are proposed to minimize the technical
difficulties that arise during the operation of treatment
facilities at pig farms. The author believes that using a decanter
for manure separation, the highest retention rate, high reliability,
high automation and process safety will be obtained.
Together, this will not allow the company to operate the treatment plant in a stable and predictable way, to have predictable costs in the long term, and to dispose of manure with economic benefit.
Late Cretaceous to early Cenozoic hydrothermal fluid migration and red calcite formation in the Transdanubian Range, Hungary
Authors: Demény Attila , Rinyu László , Dublyansky Yuri
Published: November 2024

Red calcite veins are found in Mesozoic limestones at several locations within the Transdanubian Range, western Hungary. Opinions on the origin and the formation conditions of the red calcites vary widely, with concepts ranging from high-temperature hydrothermal processes to speleothemic formation. The present study aims to constrain the formation temperatures and determine the fluid origins of the red calcites. Samples were taken from three locations previously investigated in earlier studies: the Sintérlap quarry at Sümeg, the Keselő Hill quarry at Tatabánya, and the Piliscsaba–Jászfalu quarry at Piliscsaba. Formation temperatures for the dark red calcites, presumably the earliest, ranged between 30 and 37 °C, as determined by the clumped isotopes method. The oxygen isotope compositions (δ18O) of the calcite-forming water were calculated using clumped isotope temperatures and the δ18O values of calcite. These calculations revealed a fluid that had either undergone high-temperature water-rock interaction or contained an 18O-enriched component and the temperatures are much lower than thought previously, but higher than those of speleothems. The hydrogen isotope compositions of inclusion-hosted waters, along with the carbon and oxygen isotope values of red calcites, suggest that the three red calcite occurrences were caused by distinct fluid movements, likely at different times. This indicates that a single red calcite formation event can be ruled out.

Processing of apatite raw materials is associated with the formation of multi-tonnage waste - phosphogypsum. The content of rare-earth metals in such waste reaches 1 %, which allows us to consider it a man-made source of rare-earth metals and their compounds. Until now there are neither processing enterprises nor effective technological processes for phosphogypsum processing. It is rational to use a method involving the extraction of valuable components and the overall reduction of phosphogypsum volumes. One such method can be the sorption extraction of REM after leaching of phosphogypsum with hydrochloric acid. In this work the results of sorption by sulphocationites are presented: Purosorb SAC 140 (in H- and Na-forms); Purolite C150 (in H- and Na-forms) and Puromet MTC 1600 (in H- and Na-forms).

Innovative strategies for developing straightforward and efficient technologies are necessary due to the depletion of conditioned ore sources and the rising proportion of low-grade and technogenic raw materials utilized in production. Special emphasis is placed on flotation agents, as flotation is a primary method for processing low-grade, challenging thin scattered ores. An analytical evaluation of the evolutionary progression of theoretical foundations for formulating fundamental flotation agents and their combinations derived from sulfur-containing compounds utilized and suggested for application in the mining sector is offered. Collective flotation reagents, both traditional and contemporary, are crucial for effective processing, particularly in froth flotation and solid-liquid separation. The pursuit of novel and enhanced reagents is both technological and ecological, mirroring the dynamic difficulties faced by the business. This work aims to summarize and analyze the existing theory and practice of using collector mixes in sulfide flotation, encompassing both practical applications and research, to offer insights and recommendations for developing a predictive technique.

Stereotactic radiosurgery for fourth ventricle brain metastases: tumor control outcomes and the need for CSF diversion. Patient series
Authors: Rangwala Shivani D. , Han Jane S. , Strickland Benjamin , Yu Cheng , Ye Jason C. , Zada Gabriel
Published: November 2024

BACKGROUND

Stereotactic radiosurgery is a favorable alternative to surgery for intracranial cerebral metastases. Fourth ventricle (V4) metastases are challenging because of the location and surrounding structures, with a high risk for obstructive hydrocephalus and brainstem compression. Here, the authors evaluate the effectiveness in terms of safety, tumor control rates, and permanent cerebrospinal fluid (CSF) diversion of primary Gamma Knife radiosurgery (GKRS) in treating V4 metastases.

OBSERVATIONS

Eleven of 1060 patients had V4 brain metastases. No patients had pre-GKRS hydrocephalus. The mean tumor volume was 3.3 cm3, treatment dose was 18 Gy to the 50.5% isodose line (average 14 shots), conformity index was 1.4, and volume of brainstem receiving greater than 12 Gy was 0.2 cm3. Eight patients had radiographic and clinical follow-ups. The average time to initial follow-up was 3.1 months. Karnofsy Performance Status did not change from the initial consultation to the post-GKRS follow-up. No patients developed hydrocephalus or required permanent CSF diversion. One patient required transient external ventricular drain placement; however, neurological symptoms resolved with steroid therapy. Seven patients received steroid therapy post-GKRS. Seven patients had radiographic disease control at the 6-month follow-up. One patient had tumor progression at 6 months and underwent surgery.

LESSONS

Primary GKRS for V4 metastases with a close follow-up is safe and optimizes quality of life for patients with significant cancer burden.

Automatic Denoising of Seismograms using Fingerprints: Algorithms, Properties, Limitations
Authors: Silkin K. Yu.
Published: November 2024

This article describes the new technique for automatically preparing a noisy seismic record for further analysis using expert information systems. The technique is based on seismogram fingerprints, which, due to their concise but informative pattern, allow the development of a reliable algorithm for finding important noise characteristics. The search for the optimal cutoff frequency for a high-pass filter is especially important under conditions of partial overlap of the signal and noise spectra at a high intensity of the latter. It is precisely this difficult case that this study aims to address. The article analyzes the developed methodology on the example of several hundred registrations of regional earthquakes and explosions. The analysis showed that reliable results can be achieved in more than 90% of cases. In addition to all the problems and limitations of the method, which are an extension of its capabilities, are mentioned. Appendix to the article contains detailed description of the algorithm underlying the method.
Longevity in males and females of Aedes (Ochlerotatus) cantans (Meigen) and A. (O.) communis (De Geer) (Diptera, Culicidae)
Authors: Razygraev A. V.
Published: November 2024

Longevity of adult males and females of mosquitoes Aedes (Ochlerotatus) communis (De Geer) and A. (O.) cantans (Meigen), emerged and reared in laboratory conditions, was estimated. Imagines were reared in groups in specially constructed containers with free access to sucrose and water, with mean environmental temperature of 21–22 °С, 50% air humidity inside containers, and natural light regimen. A separate group of A. cantans was reared from eggs (embryos), collected with fallen leaves from under snow. It was recognized that adult males of both species live shorter than their conspecific females. Longevity in A. cantans, in general, is greater than in A. communis; the statistically significant interspecific differences were revealed when survival curves of males were compared. Maximum recorded longevity was 42.5 and 74 days for adult females of A. communis and A. cantans, respectively. Adult females of A. cantans, reared from embryos under laboratory conditions at mean water temperature of 19°C, had the mean life expectancy similar to that obtained for conspecific adult females reared from larvae and pupae collected in nature (40 and 34 days, respectively). Two groups of their male counterparts had identical mean life expectancy values (15 days). The results mean that A. cantans adults are more convenient than adults of A. communis for prolonged experiments under laboratory conditions. Probably, adults of A. cantans reared from embryos are, in general, not less viable than their conspecifics hatched and developed at pre-imaginal stages in natural conditions.

Russian Association of Proletarian Writers: Materials for the History of the Literary Organization
Authors: Bystrova O. V.
Published: November 2024

Abstract. The article analyzes archival materials on the history of the Russian Association of Proletarian Writers (RAPP), representing it from its origins in the form of the Section of Proletarian Writers at the LITO of the NCP of the RSFSR and the All-Russian Union of Proletarian Writers to the All-Russian / The All-Union Association of Proletarian Writers (VAPP) and the final organizational design as a RAPP at the First All-Union Congress of Proletarian Writers (1928). The internal processes of the formation of the APP are presented: organizational dissociation from the MAPP, the struggle against the Napost minority, the “Literary Front”. Archival data on the liquidation of the RAPP allow us to conclude that the Organizing Committee of the USSR Writersʼ Union could not do without the experience and accumulated literary practices of the RAPP in its further activities. The history of the Proletarian Writersʼ Association studied in the article is based on the statutory documents, transcripts of meetings, resolutions, memos of this institution, which are an important source for a general understanding of the domestic post-revolutionary literary process. They also serve as a source of data on the creative biographies of writers of the 1920s and 1930s.
Principles and Methods of Digital Lexicography

Published: November 2024

Abstract. The article describes the principles and methods of digital lexicography. It begins by defining the four main stages of the lexicographic process: 1) writing up the dictionary, 2) editing and developing the book layout, 3) publishing, and 4) the post-publication period. The following section focuses on stage 1, comparing the compilation of example corpora for dictionary preparation in the past (using millions of cardboard cards) with modern tools for lexical analysis provided by web corpora like the Russian National Corpus (ruscorpora.ru). The overview of the advancements in finding examples illustrating word usage is followed by an exploration of the ways dictionary writing methods have evolved.
The analysis of computer-based dictionary writing methods starts with a discussion of the two most popular approaches: file-based and tabular. The former involves composing dictionary files with thousands of entries using text editors like Microsoft Word, resulting in poorly structured entries with inconsistent markup. The latter, however, represents each entry as a raw with entry zones (forms, meanings, examples, etc.) arranged in separate columns. The section outlines the challenges of these methods, emphasizing their limitations in publishing options and handling complex linguistic data, often employing many-to-one relationships. Alternatives such as Text Encoding Initiative (TEI) formats and database utilization are discussed, highlighting their capacity for structured data representation.
Subsequently, dictionary writing systems (DWS) are introduced, with the OnLex platform serving as a primary example illustrating their functionality. It demonstrates how online editing interfaces streamline lexicographic processes, from data input to publication and feedback collection. By analyzing DWS features, the article emphasizes their efficacy in simplifying the editorial workflow and enhancing user experience.
A critical appraisal of the advantages of online DWS is provided, highlighting their role in addressing key challenges faced by traditional publishing methods. Notable advantages include seamless integration of search functionalities, support for multiple languages, and real-time error reporting mechanisms after publication.
In conclusion, the article advocates for the wider adoption of digital lexicography methods, particularly within the Russian tradition, emphasizing their potential to facilitate every stage of the dictionary creation process.
Forms of Design Resistance in the Temporarily Occupied Territories of Ukraine
Authors: Budnyk Andriy
Published: November 2024

The purpose of the study is to investigate design forms of creative resistance to Russian aggression in the temporarily occupied territories. Research methods involve combining art analysis with documentary recording of resistance efforts under occupation conditions. Scientific novelty. It consists in the introduction into scientific circulation of previously undescribed and unanalyzed volume of works of graphic design or related to it, which were created either in the occupied territories, or for use in such territories. For the first time, the types of graphic design used for underground work are defined, the stylistics, means and methods of execution are analyzed. Conclusions. Graphic design uses creative techniques and technologies that can be effectively used in resistance actions in the occupied territories. The effectiveness of graphic design is determined by the ability to express itself in many areas of application in various forms, including: stickers, money, postcards, illustrations, posters, newspapers, growth figures, street graffiti, etc. As a result of the conducted art analysis of the body of works, the ideological motivation, specifics of performance, and stylistics of the visual aids, which use widespread forms of functioning of graphic design in the modern world, were established. Despite the partial isolation from Ukraine, the information coming from the controlled territory of the state was enough for Ukrainian artists to invent creative technologies and create appropriate samples in the conditions of a total ban on Ukrainian content by the occupying administrations and sufficiently severe punishment for violating the rules established by the aggressors. The presence of the Russian language and paraphernalia in the mentioned works is a requirement for the effective performance of the task and targeting the target audience.

The objective of this study is to conduct a systematic investigation into the utilization of cutting-edge advancements in science, technology, and art in the creation of an inclusive environment. Methodology: To examine contemporary trends in design and design education regarding the application of advanced technologies in the development of an inclusive environment, methods such as theoretical and empirical analysis, comparison, synthesis, and generalization were employed. These methods were utilized to study theoretical research materials, scientific sources, and design works. The research also relies on deduction and induction methods, as well as interdisciplinary synthesis. The scientific novelty lies in proposing, for the first time after a comprehensive analysis of developed design projects, an algorithm for their improvement from the perspective of applying "Smart Home" technology. It demonstrates how the application of modern design activity technologies in the educational process contributes to the creation of an inclusive environment. Conclusions: The utilization of smart home technology in various social sectors and ensuring accessibility for different categories of people in various spheres of life enables the improvement of the quality of life for population groups whose lives are constrained by their home environment. It illustrates how smart home technology can be integrated into the design process by investigating the issue of determining the most suitable type of technology to meet people's needs. In addition to inclusionrelated matters, these technologies concurrently address ecological, resource, and energy conservation issues. Project-based learning most closely mirrors the professional activities of a designer and shapes professional competencies. At the master's level of industrial design education in the study of the discipline "Design Planning," opportunities for the use of smart home technologies in design activities are outlined by adapting existing intelligent systems to new application conditions. This has led to the identification of a significant number of ideas for further exploration of unconventional solutions in the design of inclusive environments.

Published: November 2024

We propose a magnetic-geared motor with controllable step-out torque. The operational principle which controls the step-out torque using DC currents is described. The controllable step-out torque characteristics are computed using finite element method. In addition, the load characteristics under vector control are also computed using finite element method. Two inherent characteristics are observed in this analysis result. One is that this magnetic-geared motor can generate the torque more than the step-out torque. The other is that the phase angle difference between the rotors when both rotors step out is around 30 deg. In this paper, the mechanism of these inherent characteristics is investigated by finite element method, and these inherent characteristics are verified by carrying out measurements on a prototype.
