Inverse Solution of Thermoacoustic Wave Equation for Cylindrical Layered Media
Authors: Elmas Demet , Uzun Banu Ünalmış
Published: March 2022

Thermoacoustic imaging is a crossbred approach taking advantages of electromagnetic and ultrasound disciplines, together. A significant number of current medical imaging strategies are based on reconstruction of source distribution from information collected by sensors over a surface covering the region to be imaged. Reconstruction in thermoacoustic imaging depends on the inverse solution of thermoacoustic wave equation. Homogeneous assumption of tissue to be imaged results in degradation of image quality. In our paper, inverse solution of the thermoacoustic wave equation using layered tissue model consisting of concentric annular layers on a cylindrical cross-section is investigated for cross-sectional thermoacustic imaging of breast and brain. By using Green’s functions and surface integral methods we derive an exact analytic inverse solution of thermoacoustic wave equation in frequency domain. Our inverse solution is an extension of conventional solution to layered cylindrical structures. By carrying out simulations, using numerical test phantoms consisting of thermoacoustic sources distributed in the layered model, our layered medium assumption solution was tested and benchmarked with conventional solutions based on homogeneous medium assumption in frequency domain. In thermoacoustic image reconstruction, where the medium is assumed as homogeneous medium, the solution of nonhomogeneous thermoacoustic wave equation results in geometrical distortions, artifacts and reduced image resolution due to inconvenient medium assumptions.
Detecting Local Opinion Leader in Semantic Social Networks: A Community-Based Approach
Authors: Yang Hailu , Liu Qian , Ding Xiaoyu , Chen Chen , Wang Lili
Published: March 2022

Online social networks have been incorporated into people’s work and daily lives as social media and services continue to develop. Opinion leaders are social media activists who forward and filter messages in mass communication. Therefore, competent monitoring of opinion leaders may, to some extent, influence the spread and growth of public opinion. Most traditional opinion leader mining approaches focus solely on the user’s network structure, neglecting the significance and role of semantic information in the generation of opinion leaders. Furthermore, these methods rank the influence of users globally and lack effectiveness in detecting local opinion leaders with low influence. This paper presents a community-based opinion leader mining approach in semantic social networks to address these issues. Firstly, we present a new node semantic feature representation method and community detection algorithm to generate the local public opinion circle. Then, a novel influence calculation method is proposed to find local opinion leaders by combining the global structure of the network and local structure of the public opinion circle. Finally, nodes with high comprehensive influence are identified as opinion leaders. Experiments on real social networks indicate that the proposed method can accurately measure global and local influence in social networks, as well as increase the accuracy of local opinion leader mining.

Circular RNAs (circRNAs) are key regulatory factors with vital functions in various biological activities. However, little has been reported concerning the genetic regulation of circRNAs during rumen development in goats. The aim of this study was to identify the genome-wide expression profiles of circRNAs in the rumen of goats during fetal development and before and after weaning. Histological morphology showed that from the fetal period (days 60 and 135 of gestation) to the prepuberal period (days 60 and 150 of age) the rumen papilla developed gradually, and the thickness of the rumen muscular layer increased. A total of 11,149 circRNAs were identified in the four development stages by RNA-sequencing. From this, 1,518 were differentially expressed circRNAs (DECs). Fifty-eight DECs were up-regulated from 60 to 135 days of gestation, and 93 from day 135 of pregnancy to 30 days after birth. A large proportion (598) of DECs were down-regulated from day 135 of gestation to 30 days after birth. The expression levels of six randomly selected circRNAs were validated by qPCR, and their back-splicing junction (BSJ) sites were also confirmed. Ontology and pathway analyses revealed that the parental genes of DECs were mainly involved in the signaling pathways related to cell proliferation and apoptosis. The interaction network of circRNAs with their target miRNAs showed its involvement in cell proliferation and apoptosis signaling pathways. In conclusion, we identified the genome-wide expression profiles of circRNAs in the rumen of goats during fetal development and before and after weaning. These results provide a basis for further study on the regulatory effect of circRNAs on the development of rumen tissues.

Published: March 2022

Higher education in the 21st century faces the challenge of changing the way in which knowledge is conveyed and how teachers and students interact in the teaching-learning process. The current pandemic caused by SARS-CoV-2 has hastened the need to face up to this challenge and has furthered the need to approach the issue from the perspective of digitalisation. To achieve this, it is necessary to design training programmes geared towards teaching staff and which address both the use of technology and instructional design aimed at promoting the development of self-regulated learning (SRL) and automatic feedback systems. In this study, work was carried out with 23 teachers (8 inexperienced and 15 experienced teachers) in a training programme conducted through Moodle. The aims were: (1) to test whether there were any significant differences between the behaviour patterns of new teachers compared to experienced teachers, (2) to determine whether clusters of behaviour patterns corresponded to the type of teacher and (3) to ascertain whether the level of teacher satisfaction with the training activity in digital teaching will depend on the type of teacher. A quantitative as well as a qualitative design was applied. Differences were found in the behaviour patterns in the training activities for the development of rubrics and use of learning analytics systems in virtual learning environments. It was also found that the type of teacher did not correspond exactly to the behaviour cluster in the learning platform. In addition, no significant differences were found in the level of satisfaction between the two kinds of teacher. The main contribution this study makes is to provide a detailed description of the training stage as well as the materials required for its repetition. Further analytical studies are required on teacher perception of training programmes in digital teaching in order to provide personalised training proposals that lead to an effective use of teaching in digital environments.

Authors: Lyu Tao , Tang Lijun , Yang Zeyun
Published: March 2022

The aim of this study was to improve the entrepreneurial performance (EP) and sports morality of college teacher-and-student entrepreneurs (i.e., college entrepreneurs). Consequently, psychological capital (PsyCap) is creatively combined with social and political education (SPE) to explore college entrepreneurs’ EP and sports morality. First, following a theoretical model implementation, this article proposes several hypotheses. Then, a questionnaire survey (QS) was designed, and the data were analyzed. The results show that (1) gender has little impact on EP and sports morality; (2) PsyCap significantly affects the EP of college entrepreneurs at the age of 33–38 years; (3) in terms of educational background, average scores of PsyCap + SPE of bachelors are the highest, followed by masters or above, and finally, the college undergraduate; (4) the average score of PsyCap + SPE of married respondents is 4.0, while that of the unmarried is 3.7; (5) there is a significant difference between college entrepreneurs’ EP under the dimension of the basic enterprise situation; and (6) the average score of the length of entrepreneurship is 9.87, which has the most significant impact on the EP and sports morality, and the significance of sports morality is 0.04. Among them, the most significant impact on EP and sports morality is weekly sports participation, with a score of 9.67. Therefore, PsyCap + SPE plays a positive role in the EP of college entrepreneurs. In contrast, sports morality has little impact on EP. This study provides a reference for the research on the influence of entrepreneurship and sports morality of college entrepreneurs.

Published: March 2022

School enterprise cooperation, as the basic school running form of applied undergraduate education, is an important way to cultivate applied talents. However, at present, the lack of motivation for enterprises to participate in school enterprise cooperation and the resulting problem of “school hot and enterprise cold” seriously limit the talent training quality in China’s application-oriented universities. There is an urgent need to explore the influencing factors and mechanisms of enterprises’ participation in school enterprise cooperation to improve the training quality of applied talents. Taking Ajzen (2002) Theory of Planned Behavior as the theoretical framework, this study constructs the influencing factor model of enterprise participation in school enterprise cooperation from four aspects, namely, behavior attitude, subjective norms, perceived behavior control, and behavior intention. In this study, participants (N = 250) completed a questionnaire assessing their participation in school enterprise cooperation, which was analyzed by a structural equation model. The results show that the behavior attitude and perceived behavior control of enterprises have a significant positive impact on their intention to participate in school enterprise cooperation and then have a significant positive impact on the school enterprise cooperation behavior of enterprises. The behavior intention and perceived behavior control of enterprises have a significant positive impact on their participation in school enterprise cooperation. The policy environment has a significant regulatory effect on the relationship between the intention and behavior of enterprises’ participation in school enterprise cooperation. Therefore, from the perspective of enhancing the intention of enterprises to cooperate, colleges and universities should establish the awareness of win-win cooperation and meet the interest demands of enterprises in school enterprise cooperation in order to improve the behavior attitude and intention of enterprises. From the perspective of the formation conditions of school enterprise cooperation, with the help of industry associations, an information service platform for school enterprise cooperation should be built in order to eliminate the information islands between enterprises and universities. From the perspective of the needs of school enterprise cooperation environment, government departments should strengthen the policy support for school enterprise cooperation in order to eliminate the worries of enterprises’ participation in school enterprise cooperation.
From Photon Beam to Accelerated Particle Beam: Antimetastasis Effect of Combining Radiotherapy With Immunotherapy
Authors: Ma Liqiu
Published: March 2022

Cancer is one of the major diseases that seriously threaten the human health. Radiotherapy is a common treatment for cancer. It is noninvasive and retains the functions of the organ where the tumor is located. Radiotherapy includes photon beam radiotherapy, which uses X-rays or gamma rays, and particle beam radiotherapy, using beams of protons and heavy ions. Compared with photon beam radiotherapy, particle beam radiotherapy has excellent dose distribution, which enables it to kill the primary tumor cells more effectively and simultaneously minimize the radiation-induced damage to normal tissues and organs surrounding the tumor. Despite the excellent therapeutic effect of particle beam radiotherapy on the irradiated tumors, it is not an effective treatment for metastatic cancers. Therefore, developing novel and effective treatment strategies for cancer is urgently needed to save patients with distant cancer metastasis. Immunotherapy enhances the body's own immune system to fight cancer by activating the immune cells, and consequently, to achieve the systemic anticancer effects, and it is considered to be an adjuvant therapy that can enhance the efficacy of particle beam radiotherapy. This review highlights the research progress of the antimetastasis effect and the mechanism of the photon beam or particle beam radiotherapy combined with immunotherapy and predicts the development prospects of this research area.

Published: March 2022

Environmental health inequalities in cities of the Global South are hardly studied up to now, though they are expected to increase due to rapid urbanization and motorization taking place in many of these cities. In this study, environmental inequalities in the city of Kathmandu, Nepal for the years 2013 and 2021 are analyzed. The goal of the study is to determine the degree of environmental inequalities and their changes over time. The study examines horizontal and vertical inequalities in access to drinking water sources, air and noise pollution exposure, and health effects based on self-reported household data. Results show statistically significant environmental inequalities between neighborhoods in Kathmandu regarding access to basic water infrastructure, air and noise pollution exposure, and resulting health effects. Inequalities between socio-economic groups are not significant. Over time, the perceived exposure to air pollution has increased, mainly due to increased motorized traffic, whereas vertical inequalities persisted. While inequalities between socio-economic groups have not increased, the high socioeconomic group reveals more concerns and awareness about environmental burdens than the low socioeconomic group. In conclusion, given the intertwined horizontal and vertical inequalities, any planning response action needs to consider the population's vulnerability to target interventions to the most affected areas.

Are you worried about the climate and biodiversity crises and related events like heavy rainfalls and floods, high carbon emissions, sudden heat waves, or loss of species? Are you already doing something to help solve these problems? To reduce flood risks, we can give rivers more space by reconnecting floodplains. To store carbon and help to slow down climate change, we can protect and establish wetlands or mangroves. To make cities cooler in summer, we can plant trees and install rooftop gardens. These efforts to help combat societal problems are known as nature-based solutions. To use nature-based solutions effectively, we need to understand how we can work with nature and the steps we must take to put these ideas into practice. In this article, we introduce you to the concept of nature-based solutions and how they can help solve the climate and biodiversity crises.

The aim of this study was to determine the relationship between mindfulness practices and the psychological state and qualification of kyokushin karate athletes. The survey was conducted using the Mindful Attention Awareness Scale (MAAS-15) and the Depression, Anxiety and Stress Scale (DASS-21). The study involved 371 Lithuanian kyokushin karate athletes (of which 59.3% were male and 40.7% were female; 71.4% of research participants have practiced this sport for 11 and more years and have the 1st dan or a higher belt). The results of the study showed a positive impact of mindfulness in reducing stress experienced by athletes, improving their psychological state, and enhancing their athletic performance. A moderate negative correlation was identified between stress, anxiety, and mindfulness, and while the mindfulness score was increasing, the severity level of depression was decreasing. Meanwhile, the correlation of the meditation effect and anxiety with kyokushin karate 0–7 kyu belt was very weak but statistically significant. The research results could be useful not only for athletes and their coaches but also for sports organizations. After analysing the benefits of mindfulness for kyokushin karate athletes, mindfulness practices are proposed for the effective improvement of athletes’ physical and psychological state when preparing for professional-level competitions.

CONSTRUCCIÓN DE LA TRAMA Y URDIMBRE DE UNA CIUDAD EN EL SIGLO XVI: SANTA MARÍA DE LA ASUNCIÓN MISANTLA, VERACRUZ, MÉXICO
Authors: Ruiz Gordillo Javier Omar
Published: March 2022

Santa María de la Asunción Misantla surge de la congregación de varios pueblos indígenas de la sierra de Chiconquiaco en el Estado de Veracruz, México, durante las primeras décadas del siglo XVI, siguiendo el modelo que había aplicado Fray Nicolás de Ovando en Santo Domingo en 1502, Hernán Cortés en la Veracruz en 1524, y que Felipe II autorizaría su publicación, parcial, en 1573 del libro II de las Ordenanzas de descubrimientos, nueva población y pacificación de las Indias y publicadas en su totalidad hasta el 3 de mayo de 1576 para reordenar las nuevas fundaciones pero, en el fondo para proveer a la Nueva España de una organización política y administrativa.

¿Qué tiene, entonces, de particular esta ciudad? La trama y urdimbre del urbanismo de Misantla refleja no únicamente el acatamiento de tales ordenanzas, aún no escritas, pero ya impulsadas en la práctica de anteriores asentamientos como la misma ciudad de México en 1524 o la de Puebla, en 1531; sin embargo, en esta Misantla de 1531 los indígenas repiten un patrón de composición de pueblos reflejando su conocimiento del mundo repartido en cuatro rumbos o cuarteles.

Si bien, los indígenas totonacos abandonaron sus pueblos y fueron reubicados entre 1531 y 1564, el urbanismo es una clara representación del mundo en cuatro lados y el centro del universo u ombligo al cual consideraban el centro del cosmos, esquema que se advierte en el urbanismo de múltiples pueblos prehispánicos como Tenochtitlan o Teotihuacan y sigue repitiéndose en algunas poblaciones, entre ellas en Zinacantán, al sur de México, en el Estado de Chiapas, o al norte, entre los huicholes, tanto en sus milpas como en las obras de arte.

El presente trabajo muestra un estudio de caracterización mediante técnicas arqueométricas, de los materiales utilizados para la fabricación de un saxofón “Weltklang” proveniente de la, por entonces, República Democrática Alemana. Para tal fin se implementaron estudios de fluorescencia de rayos X, microscopía óptica, microscopía electrónica de barrido con análisis dispersivo de energías y termogravimetría. El saxofón fue fabricado en 1960, siendo parte de la línea de saxofones Weltklang (B&S) con el número de serie 32936, y permaneció en uso hasta el año 2002. Los resultados mostraron que el material base del ejemplar era el bronce, con una composición (Cu- 28% masa Zn); la cual se ajusta a las composiciones actuales para los bronces a nivel internacional. Con respecto al plateado observable en la superficie del instrumento, los análisis realizados permitieron determinar que éste se obtuvo probablemente mediante inmersión en un baño compuesto de cianuro de plata, cianuro de potasio y carbonato de potasio; pudiéndose determinar en consecuencia no sólo el método implementado sino también la composición del compuesto utilizado para dicho tratamiento. A su vez, se encontraron diferentes tipos de imperfecciones en las muestras que corresponden principalmente al lado interior del instrumento, lo que indica la existencia de zonas falladas en el proceso de bañado, las cuales probablemente fueron reparadas por fundición local de plata sobre esas mismas áreas defectuosas. Los datos obtenidos en este estudio muestran la potencialidad del uso de técnicas arqueométricas para poder inferir los métodos utilizados para la fabricación de instrumentos musicales antiguos, y, por consiguiente, la viabilidad de la arqueometría para la reconstrucción de modos de elaboración de aquellos instrumentos musicales que puedan recuperarse en contextos arqueológicos. Al mismo tiempo, los resultados provenientes de los análisis implementados en este trabajo demuestran la aplicabilidad de la arqueometría para casos de estudios relacionados con la arqueometalurgia histórica y la arqueología industrial.

Pandemi COVID-19 yang merebak di Indonesia dari Maret 2020 membawa dampak menyusahkan, misal pada bidang ketenagakerjaan, dimana perusahaan yang merugi karena permintaan berkurang, beberapa perusahaan di Surabaya akhirnya merumahkan pekerja, dengan dalih dipanggil lagi perusahaan saat membutuhkan, namun disini hak normatif pekerja sering diabaikan, padahal mereka, pekerja yang dirumahkan saat pandemi COVID-19 dimuat dalam  Surat Edaran Menteri Ketegakerjaan Republik Indonesia Nomor M/3/HK.04/III/2020 tentang Perlindungan Pekerja/Buruh dan Kelangsungan Usaha  Dalam Pencegahan dan Penanggulangan COVID-19, namun terdapat aturan lebih jelas yang mengaturnya.  Pada penelitian ini berfokus pada analisa secara perundang-undangan pekerja yang dirumahkan, lalu analisa pada pemenuhan hak pekerja yang dirumahkan baik itu akibat hukumnya maupun hak normatifnya. Pada penelitian ini memakai metode penelitian yuridis normatif, dimana permasalahan yang dibahas penulis yakni pemenuhan hak pekerja yang dirumahkan karena pandemi COVID-19 akan dianalisa dengan pendekatan perundang-undangan dan teoritis, penelitian ini didukung dengan data sekunder dan primer yang diperoleh penulis. Hasil Penelitian ini dapat disimpulkan bahwasanya tindakan merumahkan pekerja memang bisa dilakukan mengingat kondisi perusahaan tidak memungkinkan untuk mempekerjakannya, namun sebisa mungkin dihindari oleh perusahaan karena mengandung akibat hukum, dan jika terpaksa merumahkan pekerja perusahaan terdapat hak dan kewajiban seperti upah penuh yang wajib dibayarkan sesuai perundang-undangan ataupun apabila ada kesepakatan lain.Kata Kunci: Pandemi COVID-19, Hak Pekerja, Dirumahkan

Published: March 2022

Desde la recuperación económica en la década de los 90 la economía peruana presenta una situación favorable en cuanto a crecimiento económico; sin embargo, la desigualdad de ingresos en el país se mantiene casi constante. Bajo este contexto la presente investigación tiene como propósito estudiar la existencia de una relación estadísticamente significativa entre el crecimiento económico y la distribución del ingreso en Perú en el periodo 1990-2014, siendo importante por su contribución a brindar una mejor visión para el desarrollo de la política económica en cuanto a la disminución de la desigualdad; y preparación de medidas correctivas de corto o largo plazo. Para el desarrollo de la investigación se recopilaron datos estadísticos y se construyó un modelo econométrico de Mínimos Cuadrados Ordinarios, tomando como variable dependiente el logaritmo natural del PIB per cápita, para explicar el crecimiento y como variable independiente a la medida del nivel de desigualdad determinada por el Coeficiente de Gini, así como variables control utilizadas para dar consistencia al modelo. Los resultados sugieren la existencia de una relación cuadrática entre crecimiento económico y desigualdad de los ingresos, explican además que la economía peruana se encuentra en una primera etapa de la relación de U invertida, entre crecimiento y desigualdad, planteada en la literatura económica.

Authors: Jaiswal Hemant Kumar , Sharma Aarti
Published: March 2022

A study was undertaken on 36 F1s obtained from diallel (without reciprocals) mating design to explicate the genetic behavior of traditional and evolved basmati varieties for 14 traits. F1s were divided into traditional x traditional (T x T); evolved x evolved (E x E) and traditional x evolved (T x E) basmati types; amidst which E x E and T x E type of crosses exhibited high positive average heterosis in comparison to T x T type of crosses for yield per plant trait. Assessment of quality traits for average heterosis indicated that, all the three types of crosses were equally effective for KL, KB and LBR. Manifestation of average heterosis for KLAC was better in TxT type as none of the ExE type of crosses showed significant positive heterosis; likewise, among 20 T x E type of crosses only 3 crosses showed significant positive heterosis. Heritability in narrow sense was high for: MPL, 100-GW, NGP, YPP, KL, LBR, and KLAC.

The role of antioxidative enzymes as reactive oxygen species-scavengers under water-limited (WL) conditions was studied in five contrasting rice genotypes, including two checks (Sahabhagidhan as a tolerant genotype and IR 64 as a susceptible genotype). The experiment was performed in pots, and the irrigation was withdrawn five days before flowering for 15 days. For stress imposition, stress pots were maintained at 50% field capacity whereas nonstress pots were maintained at 100% field capacity. The antioxidant enzyme activity such as superoxide dismutase (SOD), catalase (CAT), and peroxidase (POX), was significantly increased under the WL conditions. Genotypes Sahabhagidhan and Parijata had the highest SOD, CAT, and POX activity with the lowest production of superoxide radical (O2-) and hydrogen peroxide (H2O2). At the same time, IR 64 and Prasad exhibited the lowest SOD, CAT, and POX activity, suggesting a lower potential to eliminate oxidative stress. The higher scavenging capacity of free radicals in Sahabhagidhan and Parijata was supplemented by the higher level of relative water content (RWC), membrane stability index (MSI), Maximum quantum yield of PSII photochemistry (Fv/Fm), chlorophyll content, and low lipid peroxidation which resulted in higher grain yield accompanied by higher biomass partitioning towards the grain.

The aim of this article is to draw attention to the growing phenomenon of working in retirement in the light of active and successful aging concepts. The change in attitudes towards aging, work and retirement among Poles can be seen as a kind of social process that has been ongoing since the early 1990s. Nowadays, more and more people of retirement age, anxious to remain active and independent for as long as possible, are delaying the moment of professional deactivation. The article presents the partial findings of research conducted by the author. The purpose of the qualitative study ”Attitudes towards retirement and type of reflexivity as determinants of positive aging” was to characterize the motivations for career continuation and the benefits of prolonged professional activity among people over 60. The findings—concerning participants considered professionals (n = 20) according to the International Standard Classification of Occupations ISCO-08—suggest that continuing one’s career after reaching retirement age can be considered one of the strategies for achieving successful aging.
Pedagogika pastiszu – co spodobałoby się Ignacemu Loyoli w Nowych wierszach sławnych poetów Grzegorza Uzdańskiego?
Authors: Telicki Marcin
Published: March 2022

CEL NAUKOWY: Artykuł Pedagogika pastiszu - co spodobałoby się Ignacemu Loyoli w „Nowych wierszach sławnych poetów” Grzegorza Uzdańskiego ma na celu podjęcie refleksji nad literacką stylizacją, której funkcja nie jest parodystyczna, lecz krytyczna.

 PROBLEM I METODY BADAWCZE: Autor dokonuje analizy współczesnego pastiszu, umieszczonego w teoretycznej ramie metamodernizmu (przeciwstawianego formom postmodernistycznym). Drugim problemem badawczym jest możliwość przeprowadzenia analogii między dociekaniami literaturoznawczymi a ustaleniami pedagogiki ignacjańskiej. W związku z tym analizy i interpretacje prowadzone są hermeneutyczną metodą close-reading (w części interpretacyjnej) oraz metodami komparatystycznymi (w partiach teoretycznych).

PROCES WYWODU: Praca została podzielona na pięć części. Po wprowadzeniu następuje część teoretyczna zawierająca opis przemian kulturowych we współczesnym świecie (w tym próbę diagnozy sytuacji po postmodernizmie). Następnie autor dokonuje interpretacji wybranych wierszy Grzegorza Uzdańskiego. Stają się one przyczynkiem do rozważań o poszukiwaniu podmiotowości, tożsamości, rozumienia przeszłości czy sposobów radzenia sobie z kryzysem, które okazują się zaskakująco podobne do metod proponowanych w szkole Ignacego z Loyoli (próba poprowadzenia takiej paraleli znajduje się w czwartej części tekstu). Całość zamykają konkluzje i zarysowanie perspektywy dalszych badań.

WYNIKI ANALIZY NAUKOWEJ: Autor pokazuje, w jaki sposób współczesna poezja wprowadza reprezentacje przemian kulturowych zachodzących pod wpływem mediów (na obecnym etapie możliwych do powiązania z metamodernizmem). Znajduje także punkty wspólne między poznawczo-wychowawczymi celami pastiszu a holistycznym nastawieniem duchowości i pedagogiki ignacjańskiej.

WNIOSKI, INNOWACJE, REKOMENDACJE: Zestawienie – wyłącznie częściowe z powodu braku wspólnej płaszczyzny religijno-duchowej – pokazuje możliwości niemetafizycznej lektury tekstów świeckich, które w „strukturze wrażliwości” przypominają poszukiwania duchowe.

Цель данной работы заключается в выявлении влияния русского языка на узбекскую языковую картину мира в прагмативном и когнитивном аспектах. Основное содержание исследования составляет анализ речевых единиц, употребляемых в узбекском языке и появившихся под влиянием русского языка. В статье рассмотрены конкретные примеры употребления русских слов в произведениях художественной литературы и в разговорной речи. При проведении исследования применены методы наблюдения, обобщения и сравнительного анализа. На основе изучения когнитивного и прагмативного влияния русского языка на узбекский язык и языковое сознание узбеков установлено, что под влиянием русского языка в узбекском языке часто встречаются лексемы, освоенные способом калькирования или заимствованные понятия, выраженные узбекскими словами. Результаты исследования вносят вклад в теорию изучения разноаспектных проблем языковой личности, а также могут быть использованы в университетских курсах по когнитивной лингвистике, лингвокультурологии, теории речевой коммуникации и др.
Deep Learning as an Improved Method of Preprocessing Biomedical Raman Spectroscopy Data

Machine learning has had a significant impact on the value of spectroscopy-based characterization tools, particularly in biomedical applications, due to its ability to detect latent patterns within complex spectral data. However, it often requires extensive data preprocessing, including baseline correction and denoising, which can lead to unintentional bias during classification. To address this, we present a deep learning-based signal preprocessing method capable of handling all the defects of raw Raman spectroscopy data without any need of human intervention. To achieve this, a novel deep convolutional neural network (CNN) architecture was trained on randomly generated spectra with various defects. We demonstrate that the proposed network results in faster training and that it can perform complete spectral preprocessing in a single step with more accuracy, speed, and defect tolerance than conventional methods. These improvements make it an ideal candidate for hyperspectral imaging applications in which tens of thousands of raw spectra may need to be processed rapidly. The superiority of this method is demonstrated for simulated Raman spectra, surface-enhanced Raman spectroscopy (SERS) imaging of chemical species, classification of low resolution Raman spectra of human bladder cancer tissue, and finally classification of SERS spectra from human placental extracellular vesicles (EVs). These findings encourage the future use of deep learning as a rapid and unbiased method of preprocessing spectroscopy data and may be particularly useful in biomedical applications involving large data sets from highly heterogeneous samples and signal defects of complex nature.
