Published: June 2023

Terahertz (THz) frequency generation via nonlinear optical techniques is of particular interest due to the immense potential of this type of radiation in various scientific fields, ranging from medicine to telecommunications. Selecting suitable nonlinear media for laser frequency down-conversion presents a challenging task. Considering an approach that uses nonlinear crystals with high radiation resistance, pumped by intense laser pulses near their damage threshold, we suggest the crystal of bismuth triborate (BiB3O6, BIBO). Compared to other borate-class crystals, BIBO exhibits relatively high coefficients of quadratic susceptibility. In this paper, we have studied the optical properties of BIBO samples in a wide spectral range from 0.1 to 2.1 THz at temperatures of 473, 383, 295, and 77 K using Terahertz Time-Domain Spectroscopy (THz-TDS). Furthermore, we simulated collinear three-wave interactions with nonzero efficiency for difference frequency generation (DFG) in the THz range. For the pump wavelengths of about 800 nm, we determined phase-matching (PM) conditions and compared the generation efficiency for different crystal cuts. The potential of utilizing BIBO crystal for terahertz frequency generation is discussed.

Published: June 2023

The investigation of novel approaches for forming solar cell grid lines has gained importance with the rapid development of the photovoltaic industry. Laser-induced forward transfer (LIFT) is a very promising approach for microstructure fabrication. In this work, the morphology of grid lines deposited by LIFT was investigated. A characterization scheme for solar cell grid lines was proposed. The shape of grid lines was described, combined with confocal imaging. The evolution process of grid lines from no forming to single-peak and double-peak with a variation of laser fluence was observed. According to experimental conditions, different types of grid line morphology were obtained and transfer mechanisms of silver paste were proposed based on fluid dynamics. The influence of laser fluence on the morphology of formed grid lines was explained through phenomenology and analysis. This can provide a guide for morphology control in forming the process of grid lines.

Published: June 2023

Nowadays, hyperspectral remote sensing data are widely used in nutrient management, crop yield forecasting and stress monitoring. These data can be acquired with satellites, drones and handheld spectrometers. In this research, handheld spectrometer data were validated by chlorophyll-a fluorescence measurements under natural cold stress. The performance of 16 rice cultivars with different origins and tolerances was monitored in the seedling stage. The studies were carried out under field conditions across two seasons to simulate different temperature regimes. Twenty-four spectral indices and eleven rapid chlorophyll-a fluorescence parameters were compared with albino plants. We identified which wavelengths are affected by low temperatures. Furthermore, the differences between genotypes were characterized by certain well-known and two newly developed (AAR and RAR) indices based on the spectral difference between the genotype and albino plant. The absorbance, reflectance and transmittance differences from the control are suitable for the discrimination of tolerant-sensitive varieties, especially based on their shape, peak and shifting distance. The following wavelengths are capable of determining the tolerant varieties, namely 548–553 nm, 667–670 nm, 687–688 nm and 800–950 nm in case of absorbance; above 700 nm for reflectance; and the whole spectrum (400–1100 nm) for transmittance.

The objective of this study was to meticulously examine the diverse vocal rehabilitation techniques that are employed following total laryngectomy, with emphasis on their implications on patients’ quality of life and on the determinants influencing the selection of one technique over another. We embarked on a comprehensive literature review, which concentrated on three primary rehabilitation approaches: tracheoesophageal puncture (TEP) accompanied by a vocal prosthesis, esophageal speech acquisition, and electrolarynx utilization. The outcomes assessed included quality of life, functional performance, communication effectiveness, patient satisfaction, and factors governing the choice of technique, such as patient demographics, disease stage, and treatment history. Our findings demonstrated that TEP with vocal prosthesis yielded the most favorable overall quality of life and patient satisfaction. Individuals who underwent TEP exhibited superior speech intelligibility, voice quality, and communication ease compared with those who employed esophageal speech acquisition or electrolarynx utilization. While esophageal speech learning exhibited inferior speech quality and functional performance, it offered cost-effectiveness and diminished maintenance advantages. Electrolarynx utilization emerged as the least preferred approach due to suboptimal speech intelligibility and voice quality. The determinants influencing the choice of vocal rehabilitation technique included patient age, sex, disease stage, and previous treatment history. Patient preferences also substantially contributed to the selection of a specific technique. It is essential for clinicians to consider individual factors and patient inclinations when deliberating on an appropriate vocal rehabilitation method following total laryngectomy. Our investigation underscores the significance of collaborative decision making between clinicians and patients to pinpoint the most fitting rehabilitation technique. Future research endeavors should be directed towards enhancing existing approaches, devising innovative methods, and probing long-term outcomes and cost-effectiveness to optimize patient care in the aftermath of total laryngectomy.

Authors: You Yuchen , Romero Javier , Diaz Graal , Evans Robin
Published: June 2023

Background: Craniofacial injuries are thought to be commonly associated with traumatic brain injury (TBI), but there is conflicting evidence in the literature. This retrospective cohort study aims to evaluate the incidence of TBI in patients with craniofacial trauma. Methods: The study included 2982 consecutive patients with either solitary or concurrent diagnoses of TBI and facial fractures, seen and evaluated at a single level II trauma center between 1 January 2010 and 31 December 2020. Continuous variables were compared against whether the patient had one or both diagnoses. Results: Of the target population, 55.8% had a solitary diagnosis of TBI; 30.28% had a solitary diagnosis of facial fractures; and 13.92% had concurrent diagnoses of both TBI and facial fractures. Patients with concurrent diagnoses had a significantly longer mean length of stay (LOS) compared to those with solitary diagnoses (9.92 ± 16.33 days vs. 6.21 ± 10.96 days, p < 0.01), but age (p = 0.68) and ICU LOS (p = 0.09) did not differ significantly between the two groups. Conclusions: Trauma to the face should be given special attention due to the increased chance of TBI with craniofacial fractures. Patients with concurrent diagnoses of TBI and facial fractures had worse hospital outcomes than those with solitary diagnoses of either TBI or facial trauma.
Acquiescence of UNESCO Cultural Heritage and Acoustic Environments: Assessment of Hanlar District
Authors: Yildirim Yalcin
Published: June 2023

Several natural and historical areas around the world are listed as UNESCO Cultural Heritage Sites. Hanlar District, located in Bursa, is the fourth biggest city in Turkey, its history includes the Ottoman, Roman, and Byzantine Empires, and it is an area with unique environmental features that represent various historical periods. Scholars at institutions worldwide have already recognized that such an environment has unique characteristics, and so local authorities should preserve the soundscape of the district as the sounds reflect the urban identity of the city. This study aims to evaluate the sounds of this unique district and recommends ways to preserve the historical and cultural heritage of the site in terms of its sounds. After collecting more than seven hundred pieces of data on sound pressure levels (SPLs) at twenty-one locations, the SPLs were statistically analyzed (an ANOVA was used for different time intervals, and a t-test was used for different days). Noon and weekend measurements varied among the sites, and these variations were statistically significant. Furthermore, the SPLs were above the WHO’s suggested levels. The study findings show the importance of reducing sounds to create better acoustic environments. The local government should include all stakeholders, including residents, employees, and urban designers, in participatory approaches and action plans to preserve the sounds of cultural heritage sites.
Comercio justo: una aproximación desde la educación superior
Authors: León Serrano Lady Andrea , Pardo Asanza Fernando Alberto , Bustos Carpio Gisella Esthela
Published: June 2023

El comercio justo, no solo se basa en comerciar productos, sino que presenta un enfoque de gestión de lucha contra la pobreza, ubicando al planeta y la integridad en primer lugar antes que el lucro, al tiempo que busca el impulso de nuevos modelos de economía en donde prime el bienestar de la sociedad y la potenciación de valores. En este sentido, el objetivo está centrado en analizar el movimiento del comercio justo, usando como sujetos de estudio, a los estudiantes de la Universidad Técnica de Machala, para obtener una reflexión sobre sus aspectos económicos y sociales, además de su influencia en las nuevas generaciones de jóvenes. La metodología responde a una investigación descriptiva simple con paradigma positivista, además de, un diseño no experimental con método inductivo y estadístico como la estadística descriptiva. Entre los resultados obtenidos, es posible apreciar que las nuevas generaciones de profesionales cuentan con altos niveles de desinformación acerca de las ventajosas funciones que cumple este tipo de comercio, así como desconocimiento de sus objetivos y principales características. En conclusión, la percepción de los encuestados ante la viabilidad futura del comercio justo se ve disminuida, demostrando que las trabas presentes en la difusión de conocimiento, formalización y el encarecimiento de los productos genera una falta de compromiso institucional, desincentivando la posible integración comercial a regímenes justos, solidarios y sostenibles.

Published: June 2023

В эпоху эпидемии коронавирусной инфекции 2019 г. (COVID-19) и борьбы с вирусом SARS-CoV-2 резко возросло число случаев глазной патологии, в частности воспалительного характера. Причиной тому может быть как сама коронавирусная инфекция, так и активная иммунизация населения вакцинами. Вакцина как триггер способна запускать каскад аутоиммунных реакций с развитием воспалительного ответа. Описано немало побочных явлений вакцинации против SARS-CoV-2. Частым осложнением перенесенной коронавирусной инфекции и вакцинации является воспаление сосудистой оболочки глаза. Значительные и порой необратимые зрительные нарушения вследствие аутоиммунного ответа, обусловленного вакцинацией или коронавирусной инфекцией, требуют высокой осведомленности врачей о возможных офтальмологических проявлениях. В статье описывается случай отдаленных офтальмологических проявлений перенесенной инфекции COVID-19 на фоне предшествующей ей иммунизации вакциной Pfizer/BioNTech (BNT162b2) против данной вирусной инфекции. С помощью высокотехнологичных методов исследования выявлены и описаны изменения заднего отрезка глаза вследствие перенесенного ранее увеита. Клинический случай демонстрирует, что COVID-19 и вакцинация против него, предположительно, могут играть роль в индукции иммунного ответа с развитием воспалительного процесса глаз.

In the era of the epidemic of coronavirus infection in 2019 (COVID-19) and the fight against the SARS-CoV-2 virus, the number of cases of ocular pathology, in particular of an inflammatory nature, has sharply increased. The reason for this may be both the coronavirus infection itself and the active immunization of the population with vaccines. The vaccine as a trigger is able to trigger a cascade of autoimmune reactions with the development of an inflammatory response. Many side effects of vaccination against SARS-CoV-2 have been described. A common complication of a coronavirus infection and vaccination is inflammation of the vascular membrane of the eye. Significant and sometimes irreversible visual disturbances due to an autoimmune response caused by vaccination or coronavirus infection require high awareness of doctors about possible ophthalmological manifestations. The article describes a case of distant ophthalmological manifestations of a COVID-19 infection against the background of a previous vaccination Pfizer/BioNTech (BNT162b2) against this viral infection. With the help of high-tech research methods, changes in the posterior segment of the eye due to previously transferred uveitis have been identified and described. A clinical case demonstrates that COVID-19 and vaccination against it, presumably, can play a role in the induction of an immune response with the development of an inflammatory of eye.

В связи с увеличением числа пациентов, страдающих миопией, и широким распространением использования различных гаджетов в настоящее время актуальной является оценка необходимости разработки и дальнейшего применения разного рода методик, направленных на прогнозирование и лечение или профилактику прогрессирования данного заболевания. Цель работы – выполнить обзор современных (на 2022 г.) научных методов прогнозирования развития миопии, а также проанализировать аспект новых методов диагностики и профилактики. В работе рассмотрены исследования по диагностике, в основе которых лежат методы интеллектуального анализа данных и машинного обучения, а также способы корректировки и лечения прогрессирующей миопии, в число которых входят специальные устройства-тренажеры и различные цифровые сервисы, анализ которых показал, что на настоящий момент не разработан тренажер, совмещающий одновременно диагностику близорукости и коррекцию процесса тренинга. Однако существуют все технологические решения для реализации подобного рода цифрового сервиса для офтальмологической помощи. Таким образом, создание программного обеспечения, объединяющего персональные диагностические большие данные и процесс тренинга зрения, имеет высокую востребованность в офтальмологической помощи.

Due to the increase in the number of patients suffering from myopia and the widespread use of various gadgets, it is currently urgent to assess the need for the development and further application of various methods aimed at predicting and treating or preventing the progression of this disease. The purpose of this work is to review modern (for 2022) scientific methods for predicting the development of myopia, as well as to analyze the aspect of new methods of diagnosis and prevention. The paper considers diagnostic studies based on methods of data mining and machine learning, as well as ways to correct and treat progressive myopia, which include special devices-simulators and various digital services. An analysis of the latter was carried out, which showed that at the moment no simulator has been developed that combines the diagnosis of myopia and correction of the training process at the same time. However, there are all technological solutions for the implementation of this kind of digital service for ophthalmic care. Thus, the creation of software that combines personal diagnostic big data and the process of vision training is in high demand in ophthalmic care.

Authors: Smith Sean James
Published: June 2023

The COVID-19 pandemic has caused widespread disruptions in educational institutions, presenting a challenging routine for working students who juggle employment and academic pursuits. This study aims to uncover the lived experiences of post-pandemic working students in the context of face-to-face learning. A descriptive phenomenological approach was employed to explore and capture their experiences. Purposive sampling was utilized to collect data from seven working students who met the inclusion criteria. The data analysis followed Braun and Clarke’s (2006) method, involving the extraction of codes, categories, and themes from the responses obtained through semi-structured interviews. As a result of the analysis, six major themes emerged: (1) financial struggles, (2) personal objectives, (3) time and schedule adjustments, (4) struggles with utilizing physical and social skills, (5) paying off debt, and (6) futurism. The findings indicate that working students require time to adapt and overcome the challenges and difficulties presented in the post-pandemic period. Therefore, it is crucial to provide them with support and measures to ensure that their studies and employment are not compromised.

Authors: Vishniakou U. A. , YiWei Xia
Published: June 2023

The results of studying the parameters of the spectra of speech signals by machine learning with the use of neural networks are presented. This study was carried out in order to confirm experimentally the possibility of performing an assessment of these parameters for the detection of Parkinson’s disease in the early stages (IT diagnostics). During the study, the public database was used, which systematized the spectra of vowel sounds uttered by patients with Parkinson’s disease. The applied method is binary data classification. In the course of the study, the speech data spectrum was first preprocessed, which consisted of filtering it in order to remove its noise components and eliminate bursts and gaps in it. Then the parameters of the processed spectrum of speech data were determined: average value, maximum and minimum, peak, wavelet coefficients, MFCC and TQWT. After that, the object was selected using the PCA algorithm. The model was trained using the Knn and Random Forest algorithms, as well as the Bayesian neural network. The Bayesian optimization algorithm and the GridSearch method were used to find the best model hyperparameters. It has been established that when using Knn, Random Forest and Bayesian neural network, it is possible to increase the accuracy of recognition of Parkinson’s disease by 94.7; 88.16 and 74.74 %, respectively. A similar study by other scientists showed that the recognition accuracy of data sets was only 86 %.

Published: June 2023

The development of technologies leads to the need of revising the methods used to obtain cryptographic keys. The randomness parameters of sequences generated by physical random sequence generators are affected by the physical parameters of the recording equipment and the environment. The requirements for the randomness of the sequence, when passing the binary test, are obtained. It is shown that as the sequence length increases, the requirements for possible deviations from the equiprobable distribution of 0 and 1 increase. The randomness stability of the sequences generated by the generator based on the study of photons is estimated. The oscillator under study consists of an LED and a compact silicon photomultiplier designed to detect low-power light radiation. Possible physical processes leading to the deterioration of the randomness of sequences are shown. The possibility of using a generator of random numerical sequences based on a small-sized silicon photomultiplier for cryptographic purposes is estimated.
The Role of Aluminum in Graphitic Carbon Nitride Synthesis from Tiourea
Authors: Maksimov S. E. , Chubenko E. B. , Borisenko V. E. , Kulak A. I.
Published: June 2023

The synthesis of a composite material based on graphitic carbon nitride by pyrolytic decomposition at 550 °C of a mechanical mixture of thiourea with the addition of aluminum powder in the amount of 5–30 wt.% has been studied. According to the scanning results by means of electron microscopy, energy dispersive X-ray spectroscopy, and X-ray diffractometry the synthesized material consists of carbon nitride, aluminum sulfide, residual metallic aluminum and aluminum hydroxide. The excess of metallic aluminum is due to the partial interaction with sulfur-containing volatile substances formed during the thermal decomposition of thiourea. It is shown that the intensity and width of the photoluminescence spectra of the synthesized composites are determined by the aluminum concentration in the initial mixture. As the aluminum concentration increases from 5 to 30 wt.%, the photoluminescence intensity maximum shifts to the long wavelength region from 534 to 560 nm. This can be used to create optoelectronic devices based on the graphitic carbon nitride.

Authors: Shamyna A. Yu. , Ivaniuk A. A.
Published: June 2023

The features of building on the basis of programmable logic integrated circuits of “arbiter” physical unclonable functions (APUF) are considered. The problem of asymmetry of pairs of APUF paths is indicated and the negative impact of this phenomenon on their characteristics is noted. A time measuring system based on a ring oscillator scheme, which is used to analyze the time characteristics of APUF paths, is described. A method for automatic balancing of signal propagation delays through the APUF paths based on the calculation of the corrective value is proposed. The consistency of the proposed balancing technique is experimentally confirmed based on the improvement in the characteristics of the APUF after its implementation. A digital scheme of this technique is presented, which can form the basis for the development of a delay auto correction scheme through APUF paths with different levels of autonomy.
Methodology for Calculating Course Errors when Aiming an Aircraft at a Maneuvering Air Target
Authors: Vysotski D. V. , Khizhniak E. I. , Khizhniak A. V.
Published: June 2023

The article presents theoretical calculations that explain the origin of errors in the course of an aircraft in an automated control system when pointing at a maneuvering air target. The peculiarity of pointing at a maneuvering target is related to the execution of turns, which are characterized by overloads. The curvature of the trajectory in such areas is usually approximated by a circle of a certain radius, depending on the value of the overload and flight speed to intercept. In the automated control system, the current course of the aircraft is determined as the direction of movement by two marks corresponding to the current and previous moments of information update time. For a target moving in a straight line, this approach is valid. However, in a turn where the guidance path is a curved line, the true heading will correspond to the tangent at the turn point. The difference in these approaches determines the error of the course calculation. This article provides a formulaic calculation of turn radii for flight speeds to intercept an air target and overloads, as well as the calculation of true and current courses. The peculiarity of the methodology is a strict formalized mathematical description. The article presents the dependences of heading errors from the aircraft’s intercept flight speed and overloads using the example of the Su-27 multifunctional fighter.

INKORPORASI HUKUM ISLAM KE DALAM SISTEM HUKUM NASIONAL INDONESIA
Authors: Zainuddin Asriadi
Published: June 2023

Hukum nasional Indonesia secara historis adalah kumpulan norma-norma hukum yang hidup dalam masyarakat yang berasal dari unsur-unsur hukum Islam, hukum adat dan hukum Barat. Berbicara tentang Hukum Islam, maka yang dimaksud adalah terjemahan dari dua istilah: syariat dan fikih. Syariat adalah firman-firman Allah SWT. (Al-Qurâ€™an) dan ketentuan-ketentuan Rasul-Nya SAW. (Al-Sunnah), keduanya bersifat sakral, universal dan kontemporal; berlaku untuk semua tempat dan segala zaman. Hukum Islam ini baru dikenal di Indonesia setelah agama Islam disebarkan di tanah air, namun belum ada kesepakatan para ahli sejarah Indonesia mengenai ketepatan masuknya Islam ke Indonesia. Sistem hukum Islam akan selalu menjadi penyeleksi proses legislasi nasional, karena secara filosofis, yuridis dan sosiologis kekuatan Islam menjadi cermin pembangunan Indonesia kedepan
