Metadrama in V. Mirzoev’s Works
Authors:   Institute of Philology SB RAS, Zhilichev Pavel E
Published: June 2022

This paper deals with the specifics of metadrama in Vladimir Mirzoev's works. The metatextual aspect of the communicative structure of Mirzoev’s plays is based on uti-lizing traditional actants of the dramatic intrigue, including kings, jesters, army officers, magicians, Hamlet, Don Juan, etc. Mixing references to classic and contemporary literature, Mirzoev’s texts take palimpsest (G. Genette), pastiche (R. Dyer) as a basis for developing dramatic action and tension. For example, The Tower decon-structs the archetype of Don Juan by combining the elements of the traditional plot with the iconography of the Tarot, references to well-known Russian classics, and elements of avant-garde aesthetics. Moreover, another “layer” of the “palimpsest” is formed by interactions with the “absurd authors of the past” (Harms, Pinter), weaving the position of interpretation (philological, directorial) into the discursive structure. Overall, the usage of palimpsest and pastiche corresponds with the dramatic intrigue of metamorphosis, the depiction of an absurdist cosmogony of a fictional world that stands on the deconstruction of cultural cliches and re-shaping the consciousness of both the characters and the recipients.
The togda kak Conjunction: An Invitation for Evaluation
Authors:   Herzen State Pedagogical University of Russia, Dymarsky Mikhail Ya.
Published: June 2022

General evaluation meanings are considered universal and capable of penetrating into any speech expression. On this basis, the possibility of constructing a functional-semantic field of evaluation is denied; instead, it is proposed to focus on the means – in particular, syntactic constructions – that facilitate the expression of evaluative meanings. As one of such means, a construction with a relatively young conjunction togda kak ‘whereas’ functioning in a juxtaposition sense as a coordinate one, is considered. The structure of the juxtaposition meaning is considered. It is shown that the condition licensing the occurrence of an assessment accompanying juxtaposition is the scalar character of the feature, according to which two situations are juxtaposed: if the values of this feature can be located on a certain scale, then the scale ranges are easily assigned general assessment values ‘good’ vs ‘bad’. It is emphasized that, according to the materials of the concordance of structures with the togda kak conjunction, in most of the modern Russian comparative statements estimated values are present.
Adverbs of Evaluation: Correlation of Semantic and Syntactic Properties (The Case of General and Hedonistic Evaluation)
Authors:   Lomonosov Moscow State University, Kobozeva Irina M. ,   Institute of Linguistics RAS
Published: June 2022

Considering evaluation adverbs of Russian expressing two types of evaluation we argue that the syntactic properties of adverbs are determined by their meaning. The hypothesis is that adverbs of general evaluation (the type good – bad) should have more syntactic functions, than the ones of particularized evaluation, and for this purpose adverbs of hedonistic evaluation (e.g. tasty) are studied. We briefly expose the main insights of linguistic-oriented evaluation theory of N. D. Arutyunova, and discuss syntactic functions of хорошо ‘good’, typical of general evaluation adverbs. Section 2 is devoted to adverbs of hedonistic evaluation. We argue that adverbs of the type приятно – неприятно ‘pleasant – unpleasant’ should be excluded from this class, because in their lexical meaning only the general sensory evaluation is fixed, while its specification as hedonistic or psychological is conditioned by syntactic and/or semantic context. We show that hedonistic evaluation adverbs possess lesser number of syntactic functions than general evaluation adverbs. We demonstrate syntactic differences in the degree of acceptability of the explicit experiencer and the implicit causing factor with the hedonistic evaluation adverbs, conditioned by the channel of perception encoded in adverb’s lexical meaning, and give them the cognitive explanation. The results of our analysis bring into question the syntactic criterion of adverbs with floating scope proposed by M. V. Filipenko (2003). According to this criterion the adverbs of taste and smell evaluation should have floating scope because they have predicative function, but as all hedonistic evaluation adverbs they have the fixed scope over the semantic predicate ‘feel’ implicit in their meaning. We argue that the only syntactic property that guarantees the floating scope for an adverb is its ability to govern the subordinate complement clause with the complementizer chto ‘that’.
On the epic model of the Olonkho world in the Yakut culture
Authors:   Ammosov North-Eastern Federal University, Satanar M. T.
Published: June 2022

In modern conditions of an information civilization, myth and epic are attracting much attention due to the desire to understand and comprehend the constant values of mythological knowledge of the cultural origins. This work focuses on actualizing the role of the epic world model of the Yakut epic Olonkho in the culture of the Sakha people. The purpose was to verify the epic model of the Yakut Olonkho world and to describe how this model is manifested as a cultural universal in various sign systems of the material and spiritual cultures of the Sakha people. The study involved an interdisciplinary approach, modeling methods, structural and semiotic analysis, extrapolation, deduction. It was found that the representation of the geometric scheme of the epic model of the world in the form of a pyramidal structure in a static position and a cone-shaped model in dynamics has a fundamental role in modeling various iconic systems of the Yakut national culture as a universal archetype scheme. The subconscious tendency to symbolize the world model appears in the schemes of “mythological scenarios,” in geometric and semantic embodiments of the Sakha material culture artifacts, in postulated numerical principles, and in the ways of narrating the oral folk texts. Verifying the scheme-archetype as a central symbol of the Yakut culture is of great value, containing as it does the germs of new cultural ideas developing in the modern globalizing society in the continuous movement of time, making it possible to outline the possibilities of national tradition text-forming mechanisms.
Book review: Oirotia in the Mirror of literature: an anthology. E. P. Chinina, T. P. Shastina (Eds.). Gorno-Altaysk, Poligrafika, 2020, 308 p.

Published: June 2022

The anthology under review is a collection of journalistic, literary, and academic texts in Russian and Altai that appeared in local and central periodicals and textbooks and poetic anthologies published in Moscow and various Siberian cities. The chronological period of the anthology covers the entire period of the Oyrot Autonomous Oblast existence: from 1922 to 1948. These years brought significant changes to the region: the mass spread of literacy, the Altai literature’s appearance, and the standard Altai language development. The anthology shows the formation and evolution of the image of Oyrotia, a national Soviet autonomy. The essays, articles, and poems collected under one cover reflect the perception of Oyrotia by different authors: local Altaians, travelers, writers, and journalists. The Oyrot Autonomous Oblast continued to exist until 1948 and was later renamed. The renaming order closes the anthology. A review article by T. P. Shastina, written in a deeply analytical manner, opens the book, tracing the image of Altai in documentary literature and literary fiction up to E. Limonov’s Book of Water and V. Sorokin’s Telluria. The book is provided with a dictionary, with five appendixes containing Altai lexis (old words and words found in Russian text), Siberian lexis, obsolete words, lists of persons, and texts sources. The photos from the State Archive of the Altai Republic are used as illustrations. This anthology is considered to be significant not only for Gorny Altai but also for the whole of Russia, being equally valuable for experts and readers interested in the history and culture of Gorny Altai.
Distribution of voiced fricative consonants of the Surgut dialect of the Khanty language in the position after vowels
Authors:   Novosibirsk State University, Lyapina P. A. , Ryzhikova T. R. ,   Institute of Philology SB RAS
Published: June 2022

This work aims at identifying and describing the articulatory characteristics of the bilabial and guttural consonant phonemes of the Surgut dialect of the Khanty language by distributive analysis. The Khanty language is characterized by a pronounced dialect fragmentation. The Surgut dialect is one of the Eastern Khanty dialects. A number of works are devoted to its vocalism, while only one paper addresses the Surgut consonantism. The system of the Surgut dialect consonants is characterized by several features, with one being the alternation of fricative bilabial [w], guttural non-labialized [ɣ], and guttural labialized [ɣЮ] consonants. According to experimental studies conducted in the V. M. Nadelyaev Laboratory of Experimental-Phonetic Researches, Institute of Philology, SB RAS, these sounds have been found to alternate not only in speakers of different Surgut sub-dialects but also in the speech of one speaker. This study examined the word forms with target sounds found in the dictionary of the Eastern Khanty dialects by N. I. Tereshkin. The paper presents language material, with a series of words in different phonetic contexts and a summary distribution table. Following N. S. Trubetskoy’s rules of phoneme distinction, we performed a sound analysis and identified two phonemes: the bilabial rounded phoneme /w/ and the guttural hypothetical pho-neme /ɣ/. The bilabial one was found to have two allophones [w, ɣЮ], with the guttural phoneme realized only in one allophone [ɣ].
Structural classification of analytical connectors of a complex sentence in the Khanty language
Authors:   Institute of Philology SB RAS, Koshkareva N. B.
Published: June 2022

The structural classification of analytic connectors of a complex sentence of the Khanty language follows the principles developed by M. I. Cheremisina and T. A. Kolosova in the monograph “Essays on the theory of complex sentences” (1987). Single and non-single connectors can be distinguished depending on whether the complex sentence connector belongs to one predicative unit or to both ones, with single connectors belonging entirely to one of the predicative units and non-single ones consisting of two or more parts placed in different predicative units. Also, the classification takes into account the morphological nature: in the Khanty language, the analytical connectors of a complex sentence are formed based on particles or pronouns. Further, consideration is given to the number of components in the composition of a particular connector, with single-component and multicomponent (usually two-component) connectors being identified. The specificity of the Khanty language is that there are no conjunctions since synthetic and analytical-synthetic polypredicative constructions prevail. Particles and pronouns are used to connect the parts of a polypredicative construction. However, in the language of newspapers, the fund of analyt-ical connectors is actively replenished.
Khakass non-fairytale prose in the materials of the Manuscript Fund of the Khakass Research Institute of Language, Literature and History (1945–2000s)
Authors:   Institute of Philology SB RAS, Mindibekova V. V.
Published: June 2022

The paper is devoted to the folklore heritage housed in the Manuscript Fund of the Khakass Research Institute of Language, Literature and History (KhRILLH). Systematic scientific research in the field of Khakass folklore began at the beginning of the 20th century. The regular formation of the Manuscript Fund of KhRILLH began in 1945. Now, it contains the richest materials on folklore collected during folklore and ethnographic expeditions: the “living” exist- ence of heroic epics, fairy tales, myths, legends, song genres of yr and takhpah, as well as ritual folklore. However, no sufficiently complete description of the manuscripts stored in the collection has been provided so far. The author considers the issues of differentiation and systematization of non-fairytale prose, plot, and thematic composition and characterizes the scholars’ collecting and research activities on Khakass non-fairytale prose from the middle of the 20 th – beginning of the 21st centuries. The study dealt with the archival records of the Handwritten Fund of KhRILLH, including the texts in Sagai, Kachin, Kyzyl, and Shor dialects of the Khakass language. The analysis involved archival texts deciphered from the materials of folklore expeditions. The work fills a number of gaps in the study of non- fairytale prose of the Khakasses and contributes to the further development of research in this direction. The paper is written as a result of the work on the volume of the series “Monuments of folklore of the peoples of Siberia and the Far East”.
Examination of chewing performance with extraction and non-extraction fixed orthodontic treatment – A prospective clinical 1-year study
Authors: Gözler Serdar , Sadry Sanaz
Published: June 2022

Objectives:

It shows that patients receiving orthodontic treatment may have a risk of developing temporomandibular disorder symptoms. The aim of this study is to examine the changes in the chewing system of occlusal contact parameters related to joint vibrations, chewing patterns, and measured excursive movements in fixed and non-extractive orthodontic treatments.

Material and Methods:

A total of 43 individuals with premolar extraction (n = 23) and without extraction (n = 20) who applied to the Department of Orthodontics, Dentistry Faculty of Istanbul Aydin University and needed orthodontic treatment were included in the study. In this study, 43 active fixed orthodontic treatment patients were conducted at the beginning (T0) and 6th month (T1) and 12th month (T2) on the parameter recorded during chewing. For occlusion analysis, T-Scan® computerized occlusion analysis recording and examination of the chewing pattern were used for JVA and JT temporomandibular joint parameters. Depending on whether the data showed normal distribution or not, differences between groups were evaluated using the Mann–Whitney or independent t-test, and intragroup differences were evaluated using the Wilcoxon sign test or paired t-test.

Results:

At the beginning, 6th month and 12th month of orthodontic treatment, it was observed that the opening, closing, and occlusion times and joint vibration frequencies in the chewing pattern in cases with and without tooth extraction, the integral value differences of total integral, and frequencies below 300 Hz and above 300 Hz were statistically significant (P < 0.001). In digital occlusion analysis values, the right-left differences were not found statistically significant in the measurements made in cases with and without extraction (P > 0.05), while there were statistically significant differences in disclusion values at the beginning, 6th and 12th months (P < 0.05).

Conclusion:

At the beginning of the orthodontic treatments with or without extraction, it was observed that the values at the joint level changed significantly in the 6th month. However, the changes in the joints during the treatment, when they return to their ideal values at the end of the 12th month, are more than the change in occlusion.

In their Comment (Huang, T.; Granick, S. ChemRxiv 2022) on two related publications (J. Am. Chem. Soc. 2021, 143, 20884-20890; J. Am. Chem. Soc. 2022, 144, 1380-1388), Huang et al. comment on the diffusion NMR measurements of molecules during a copper-catalyzed azide-alkyne cycloaddition (CuAAC) “click” reaction. Here we respond to these comments and maintain that no measurable diffusion enhancement was observed during the reaction. We expand on the physical arguments presented in our earlier JACS paper regarding the appropriate reference state for the diffusion coefficient and present new data showing that the use of other reference states as suggested by Huang et al. will still support our conclusion that the two reactants and one product of click reaction do not exhibit boosted mobility during the reaction.
Synthesis of 3-Borylated Cyclobutanols from Epihalohydrins or Epoxy Alcohol Derivatives
Authors: McDonald Tyler , Rousseaux Sophie
Published: June 2022

There is an increasing interest in cyclobutanes within the medicinal chemistry community. Therefore, methods to prepare cyclobutanes that contain synthetic handles for further elaboration are of interest. Herein, we report a new approach for the synthesis of 3-borylated cyclobutanols via a formal [3+1]-cycloaddition using readily accessible 1,1-diborylalkanes and epihalohydrins or epoxy alcohol derivatives. 1-Substituted epibromohydrin starting materials provide access to borylated cyclobutanols containing substituents at three of the four positions on the cyclobutane core, and enantioenriched epibromohydrins lead to enantioenriched cyclobutanols with high levels of enantiospecificity (>98% es). Finally, derivatization studies demonstrate the synthetic utility of both the OH and Bpin handles.
Multi-scale Methane Measurements at Oil and Gas Facilities Reveal Necessary Framework for Improved Emissions Accounting

Published: June 2022

Methane mitigation from the oil and gas (O&G) sector represents a key near-term global climate action opportunity. The effectiveness of mitigation strategies rests on the ability to quantify spatially and temporally varying methane emissions more accurately than existing approaches. Advances in technologies have enabled improvements in methane emissions measurements and monitoring, In this work, we demonstrate a quantification, monitoring, reporting, and verification framework that pairs snapshot measurements with continuous emissions monitoring systems (CEMS) to reconcile measurements with inventory estimates and account for intermittent emissions events. We find site-level emissions exhibit significant intra-day and daily emissions variation. Snapshot measurements of methane can span over three orders of magnitude and may have limited application in developing annualized inventory estimates. Consequently, while official inventories underestimate methane emissions on average, emissions at individual facilities can be lower than inventory estimates. Using CEMS, we characterize distributions of frequency and duration of intermittent emission events. Technologies that allow high sampling frequency such as CEMS, paired with a mechanistic understanding of facility-level events is key to accurate accounting of short-duration, episodic, and high-volume events that are often missed in snapshot surveys, and to scale snapshot measurements to annualized emissions estimates.

Published: June 2022

Aziridine synthesis from readily available alkene has been a long-standing point of interest for organic chemists, owing to the widely existence in bioactive compounds and plentiful synthetic derivatizations of aziridines. Compared with using iminoiodinane or azide as the nitrogen source, the seeking for catalytic systems employing novel nitrogen transfer reagent under external oxidant-free conditions are the cutting-edge techniques in this field. Herein, a pioneering nano-cobalt catalyzed chemo-selective aziridination/oxyamination reaction from alkene and hydroxylamine is developed, this system proceeds without external oxidant and exhibits mild, efficient, atom-economic and recyclable characters. Late-stage aziridinations of drug-derived alkenes and diversified synthetic transformation of the aziridine product further expands the utility of this method. Moreover, this novel methodology represents a rare example of alkene difunctionalization under nano-catalyst, which bridges the gap between homo- and heterogeneous catalysis. Moreover, the full characterizations of the nano-cobalt catalyst and mechanistic studies including deuterium-labeled experiment and Hammet analysis were conducted, while a reasonable mechanism was also suggested accordingly.
One-shot trajectory learning of open quantum systems dynamics
Authors: ULLAH ARIF , Dral Pavlo O.
Published: June 2022

Nonadiabatic quantum dynamics are important for understanding light-harvesting processes, but their propagation with traditional methods can be rather expensive. Here we present a one-shot trajectory learning approach that allows to directly make ultra-fast prediction of the entire trajectory of the reduced density matrix for a new set of such simulation parameters as temperature and reorganization energy. The whole 10ps long propagation takes 70 milliseconds as we demonstrate on the comparatively large quantum system, the Fenna–Matthews–Olsen (FMO) complex. Our approach also significantly reduces time and memory requirements for training.
Predicting the properties of salt water using neural network potentials and continuum solvent theory
Authors: Pagotto Joshua , Zhang Junji , Duignan Timothy
Published: June 2022

Electrolyte solutions play a fundamental role in a vast range of important industrial and biological applications. Yet their thermodynamic and kinetic properties still can not be predicted from first principles. There are three central challenges that need to be overcome to achieve this. Firstly, the dynamic nature of these solutions requires long time scale simulations. Secondly, the long-range Coulomb interactions require large spatial scales. Thirdly, the short-range quantum mechanical (QM) interactions require an expensive level of QM theory. Here, we demonstrate a methodology to address these challenges. Data from a short \emph{ab initio} molecular dynamics (AIMD) simulation of aqueous sodium chloride is used to train an equivariant graph neural network interatomic potential (NNP) that can reliably reproduce the short-range QM forces and energies at a moderate computational cost. This NNP is combined with a continuum solvent description of the long-range electrostatic interactions to enable stable long time and large spatial scale simulations. From these simulations, ion-water and ion-ion radial distribution functions (RDFs), as well as ionic diffusivities, can be determined. The ion-ion RDFs are then used in a continuum solvent approach to calculate the osmotic and activity coefficients. Good experimental agreement is demonstrated up to the solubility limit of sodium chloride in water. This result implies that classical electrostatic theory can describe electrolyte solution over a remarkably wide concentration range as long as it is combined with an accurate description of the short-range interactions. This approach should be applicable to determine the thermodynamic and kinetic properties of many important electrolyte solutions for which experimental data is insufficient.
Inducing Conductive Surface Layer on Nb2O5 via Ar-ion Bombardment: Enhanced Electrochemical Performance for Li-ion Batteries
Authors: Zhang Shaoning , Hwang Jinkwang , Sato Yuta , Matsumoto Kazuhiko , Hagiwara Rika
Published: June 2022

Niobium pentoxide (Nb2O5) is in the limelight as a negative electrode material for advanced electrical energy storage devices owing to its unique pseudocapacitive behavior. However, its intrinsic poor electronic conductivity restricts its electrochemical performance. In this study, argon-ion bombardment is employed to enhance the interfacial properties of the Nb2O5 negative electrode by introducing highly conductive NbOx (1 ≤ x ≤ 2) species on the electrode surface. The NbOx surface architecture fosters significant improvements in the reversible capacity and rate performance of the argon-ion bombarded electrode than pristine electrodes. Detailed analysis reveals that introducing the surface NbOx layer promotes charge transfer at the electrode surface and breaks the limitations of charge transfer resistance. The result provides a pathway to enhance intrinsic shortness of conductivity and to establish surface modification simultaneously via a simple argon-ion bombardment method, thus achieving the improved electrochemical performance of Nb2O5 and serving as an expedient strategy for augmenting electrode materials for advanced energy-storage applications.
LA PERSECUTORIEDAD DE LOS CRÉDITOS LABORALES
Authors: Pacheco Zerga Luz , Valdez Villalobos Mauricio
Published: June 2022

Los autores analizan el privilegio de los créditos laborales y su carácter persecutorio, a la luz de la Constitución, la legislación y del criterio sentado por la Corte Suprema. En Perú, tanto el privilegio de los créditos laborales como su persecutoriedad, son absolutos, es decir, sin límite alguno en el tope de esos adeudos. Esta condición perjudica a los acreedores no laborales de un empleador en el marco de un proceso concursal, así como a los terceros adquirentes de buena fe de los bienes transferidos por aquel. El perjuicio se ve reflejado, tanto en cuanto a la cuantía, como en el hecho de que la Corte Suprema haya otorgado jerarquía constitucional al privilegio de la persecutoriedad, lo que impide que otros derechos reconocidos a nivel legal, como es el de los terceros adquirentes de buena fe registral a título oneroso, regulado en el Código Civil, no sea oponible por considerarse de rango inferior. Se pondera la viabilidad de limitar el privilegio de los créditos laborales, teniendo en cuenta la experiencia de otros países, así como los aportes de la doctrina académica, a fin de equilibrar los derechos de cobro de los acreedores de un empleador, sin menoscabar el derecho de los trabajadores. El artículo desarrolla primero la naturaleza, definición y justificación de los créditos laborales en el marco normativo vigente. Luego, su carácter persecutorio, los presupuestos y supuestos de aplicación, sujeto pasivo y bienes sobre los que recae. Y, finalmente, la decisión de la Corte Suprema de otorgarle rango constitucional al derecho persecutorio.

Topologies and Ranks for Families of Theories in Various Languages
Authors:   Sobolev Institute of Mathematics, Sudoplatov Sergey ,   Novosibirsk State Technical University
Published: June 2022

Topological properties and characteristics of families of theories reflect possibilities of separation of theories and a complexity both for theories and their neighbourhoods. Previously, topologies were studied for families of complete theories, in general case and for a series of natural classes, and for various families of incomplete theories in a fixed language. The ranks were defined and described for complete theories in a given language, for a hierarchy of theories, for families of incomplete theories, for formulae and for a series of natural families of theories, including families of ordered theories, families of theories of permutations and families of theories of abelian groups. In this paper, we study properties and characteristics for topologies and ranks for families of theories in various languages. It is based on special relations connecting formulae in a given language. These relations are used to define and describe kinds of separations with respect to 𝑇0-topologies, 𝑇sub>1-topologies and Hausdorff topologies. Besides special relations are used to define and study ranks for families of theories in various languages. Possibilities of values for the rank are described, and these possibilities are characterized in topological terms.
Low-Code and Object Spreadsheet

The paper considers low-code application development technology based on the idea of object-oriented programming (OOP) visualization. As the core, we use a version of OOP developed by us, which supports managing object models as microservices. The paper considers visual tools for managing object models as the basis for low-code development. An approach to visualization based on the so-called object spreadsheets is proposed. The spreadsheet methodology for object structure management, its implementation within the Ontobox platform, as well as the results of testing this interface to object models are discussed

Published: June 2022

Purpose: The reactions of ratee to appraisal practices and their perceptions of appraisal system fairness may be a good indicator of appraisal system success. This research investigates employees' perception of performance appraisal (PA) aspects connected with organizational justice on Performance Appraisal effectiveness and employee satisfaction with the evaluation process in higher education.

Design/Methodology/Approach: The partial least square structural equation modeling (PLS-SEM) was employed to check the hypothesized results. Overall, 497 respondents filled the questionnaire with their views on appraisal fairness, effectiveness, and satisfaction with appraisal practices.

Findings: The findings show a positive relationship between organizational justice dimensions (socially determined justice and structurally determined justice) with effectiveness and satisfaction with the appraisal system. However, satisfaction with performance appraisal effectiveness and socially determined justice do not have a statistically significant relationship. Furthermore, there is a significant mediation relationship between the appraisal system's effectiveness, employee satisfaction with performance appraisal, socially determined justice, and structurally determining justice.

Implications/Originality/Value: The study presents some useful suggestions to managers working as appraisers on increasing the performance appraisal system effectiveness and making it acceptable for the employees with their satisfaction.
Using Digital Comics for Enhancing EFL Vocabulary Learning during the COVID-19 Pandemic
Authors: Castillo-Cuesta Luz , Quinonez-Beltran Ana
Published: June 2022

The aim of this quantitative study is to determine the impact of using digital comics to strengthen English as a Foreign Language (EFL) vocabulary knowledge during the COVID-19 pandemic. The approach was quasi-experimental with 262 public high school students from three of the four regions of Ecuador. The students’ ages ranged from 12 to 14 years and their proficiency level was A1 in accordance with the Common European Framework of Reference for Languages (CEFR). They were divided into control and experimental groups. The participants in both groups received explicit vocabulary instruction through workshops, but the experimental group had the opportunity to practise EFL vocabulary using digital comics while the control group used supplementary resources and the textbook established by the Ecuadorian Ministry of Education. The data were collected using pre-tests, post-tests, and a perception survey. Based on the statistical analysis, the results showed a significant improvement in vocabulary acquisition in the experimental group. This group also demonstrated a positive perception of the use of digital comics for enhancing EFL vocabulary knowledge because comics allowed students to create original digital stories and customise them according to their preferences. Further research might consider the use of comics for teaching specific linguistic skills in on-site learning environments.
A Compact Ultra-Wideband Chip Antenna with Bandwidth Extension Patch and Simple Isolator for MIMO Systems for Mobile Handheld Terminals

Published: June 2022

A compact ultra-wideband (UWB) chip antenna that has high isolation for multi-input multi-output (MIMO) systems is presented in this paper. The antenna is composed of a chip antenna, a printed circuit board, and an isolator stub. High isolation was obtained using a simple stub, and a low-frequency band was extended by applying a bandwidth extension patch to the chip antenna. The pulse performance of the proposed antenna was measured by changing the angle of the receiving antenna. The proposed antenna was simulated by applying a hand phantom. The effect of the grip position of the hand phantom on the reflection coefficient, isolation, and gain was analyzed. The measured impedance bandwidth was 2.45 GHz to 9 GHz. The proposed UWB MIMO antenna has a high isolation, greater than 25 dB, at the operating frequency. The antenna gain varied from 3 dBi to 4.5 dBi over the operating frequency range. The measured group delay variation was less than 1 ns. The measured pulse features have negligible chirp and a small dispersion.
A Single-Stage 12-Times Frequency Multiplier for a 5G Frequency Synthesizer
Authors: Im SungWoo , Nam Kyu-Hyun , Park Junseok
Published: June 2022

This paper presents a single-stage 12-times frequency multiplier composed of an invented harmonic generator (HG) and a modified cascode buffer. The reliable output frequency band is guaranteed from 16 GHz to 28 GHz (54.5% frequency range). The whole band is divided to 256 subsidiary frequency bands by applying 8-bit digitally controlled capacitor banks of LC (inductor and capacitor)-tuned output. The invented HG architecture is based on a double-balanced mixer, but the bottom and top differential pairs are appropriately biased to generate the required turn-on time, τ , for obtaining the more dominant desired 12th harmonic. In addition, to reduce power consumption and conversion gain variation for the target frequency band, a negative-gm differential pair is added to the HG core in parallel to enhance the equivalent parasitic resistance, which is directly proportional to the HG gain. Newly created automatic constant amplitude control is able to keep the HG amplitude output constant as well as keep it from oscillating. Further desired harmonic amplification and unwanted suppression can be achieved by the proposed cascode buffer. The proposed 12-times multiplier is fabricated on a 65-nm CMOS (complementary metal-oxide-semiconductor) process and successfully tested. Chip die size is 0.4 mm2, and power consumption is only 4 mW.
Dop-DenseNet: Densely Convolutional Neural Network-Based Gesture Recognition Using a Micro-Doppler Radar

Published: June 2022

Hand gesture recognition is an efficient and practical solution for the non-contact human–machine interaction in smart devices. To date, vision-based methods are widely used in this research area, but they are susceptible to light conditions. To address this issue, radar-based gesture recognition using micro-Doppler signatures can be applied as an alternative. Accordingly, the use of a novel densely convolutional neural network model, Dop-DenseNet, is proposed in this paper for improving hand gesture recognition in terms of classification accuracy and latency. The model was designed with cross or skip connections in a dense architecture so that the former features, which can be lost in the forward-propagation process, can be reused. We evaluated our model with different numbers of filter channels and experimented with it using the Dop-Net dataset, with different time lengths of input data. As a result, it was found that the model with 64 3 × 3 filters and 200 time bins of micro-Doppler spectrogram data could achieve the best performance trade-off, with 99.87% classification accuracy and 3.1 ms latency. In comparison, our model remarkably outperformed the selected state-of-the-art neural networks (GoogLeNet, Res- Net-50, NasNet-Mobile, and MobileNet-V2) using the same Dop-Net dataset.

The possibility of fabrication of microstructured poly-3-hydroxybutyrate films by self-assembly water microdroplets technique, using artificial templates and polymer inverse emulsions has been studied. It has been established that self-assembly water microdroplets technique allows forming ordered microstructures of poly-3-hydroxybutyrate with a hexagonal arrangement of cells with an adjustable diameter from 1 to 4 цт. It has been shown that application of inverse emulsions of poly-3-hydroxybutyrate allows us to fabricate porous films with a pore size in the range from 0.4 to 3 ^m, while the structure of the films and the pore size can be controlled by changing the polymer concentration in the dispersion medium and the volume ratio of the phases. Using spin-coating technique and artificial templates, it is possible to obtain poly-3-hydroxybutyrate microstructured replicas, which are characterized by a high degree of uniformity and the absence of defective areas. It has been shown that the formed microstructured poly-3-hydroxybutyrate films with controlled surface topography are promising for use as scaffolds for stem cells.
