Published: December 2024

В работе рассматриваются возможности двукратной пространственной обработки поля, полученной на основе метода двойного взвешенного Фурье преобразования (ДВФП), для задач повышения разрешающей способности спутниковой диагностики ионосферы с учетом горизонтальной скорости дрейфа локальных плазменных неоднородностей, с масштабами меньше радиуса Френеля. В качестве модели плазменных неоднородностей используются выражения для вариаций диэлектрической проницаемости в виде гауссовых функций.

This paper discusses the capabilities of double spatial field processing based on the Double Weighted Fourier Transform (DWFT) method for enhancing the resolution of satellite diagnostics of the ionosphere, taking into account the horizontal drift velocity of local plasma inhomogeneities with scales smaller than the Fresnel radius. Expressions for variations in permittivity in the form of Gaussian functions are used as a model for plasma inhomogeneities.

В работе представлены результаты измерения ОНЧ излучения молниевых разрядов, инициированных извержением подводного вулкана Тонга в геофизической обсерватории (ГФО) «Михнево» ИДГ РАН. На основании полученных данных определены задержки распространения сигналов. Показано, что основной сигнал приходит не по кратчайшей дуге большого круга, а с противоположной стороны, т.е. по «длинной» части дуги большого круга. Это связано с особенностями гелио-геофизических условий на трассах распространения сигнала.

The paper presents the results of measuring VLF radiation from lightning discharges triggered by the eruption of the underwater Tonga volcano at the Mikhnevo Geophysical Observatory of the Institute of Dynamics of the Geo-spheres, RAS. Based on the obtained data, the propagation delays of signals were determined. It is shown that the main signal arrives not along the shortest great circle arc, but from the opposite side, i.e., along the "long" part of the great circle arc. This is related to the peculiarities of the heliogeophysical conditions along the signal propagation paths.

IONOSPHERIC AND GEOMAGNETIC EFFECTS OF THE METEOROID EXPLOSION ON DECEMBER 19, 2014, OVER THE KOLA PENINSULA
Authors: Черняков С.М.
Published: December 2024

Рассмотрены ионосферные и геомагнитные эффекты взрыва метеороида 19 декабря 2014 г. над Кольским полуостровом. Отклик ионосферы оценен по данным приемника глобальных навигационных спутниковых систем (Мурманск) и установки частичных отражений (радиофизический полигон «Туманный»). Геомагнитная реакция рассмотрена по данным магнитовариационной станции обсерватории «Лопарская». Показано, что взрыв сопровождался резким изменением параметров среды. Предполагается, что эти изменения вызваны прохождением ударной, акустико-гравитационных и магнитогидродинамических волн.

The ionospheric and geomagnetic effects of the meteoroid explosion on December 19, 2014, over the Kola Peninsula are considered. The ionospheric response is assessed based on data from the global navigation satellite system receiver (Murmansk) and the partial reflection installation (radiophysical range "Tumannyy"). The geomagnetic response is analyzed using data from the magnetovariational station of the Loparskaya Observatory. It is shown that the explosion was accompanied by a sharp change in the environmental parameters. It is suggested that these changes were caused by the passage of shock, acoustic-gravitational, and magnetohydrodynamic waves.

В работе представлены результаты анализа данных экспериментальных кампаний 2012-2022 годов по регистрации свечения атомарного кислорода OI 630 нм в периоды воздействия на ионосферу мощного коротковолнового излучения стенда СУРА. 7 и 10 августа 2021 зарегистрированы практически идентичные по форме и дальнейшему поведению перемещающиеся образования слабой интенсивности протяженностью не менее 400 км. 7 августа 2021 г. оцененная скорость движения фронта на юго-запад составила ~104 м/с, на северо-восток ~127 м/с. 10 августа 2021 г. скорость движения фронта на юго-запад составила ~71 м/с, на северо-восток ~142 м/с. Зарегистрированные перемещающиеся структуры на данный момент нельзя однозначно связать с излучением стенда СУРА.

This paper presents the results of analyzing data from experimental campaigns conducted from 2012 to 2022 on the registration of atomic oxygen OI 630 nm emission during periods of powerful short-wave radiation exposure from the SURA stand on the ionosphere. On August 7 and 10, 2021, almost identical moving formations of weak intensity, extending at least 400 km, were registered. On August 7, the estimated speed of the front moving southwest was approximately 104 m/s, and northeast was approximately 127 m/s. On August 10, the speed of the front moving southwest was about 71 m/s, while northeast it was about 142 m/s. The registered moving structures cannot currently be unambiguously linked to the radiation from the SURA stand.

PERFORMANCE ANALYSIS OF ADAPTIVE MIMO TECHNIQUES FOR ANGULAR DIVERSITY RECEIVER-BASED VISIBLE LIGHT COMMUNICATION
Authors: Horunlu Kardelen , Çelik Yasin
Published: December 2024

Correlation between the channels is the primary factor that restricts data rates in multiple-input multiple-output visible light communications (MIMO-VLC). Different receiver designs have been proposed to reduce this correlation value, while adaptive modulations that perform better under the correlated channel effect have been studied on the transmitter side. In this study, we conducted a performance analysis of MIMO-VLC systems by utilizing adaptive MIMO modulations at the transmitter side and angular diversity receiver (ADR) structures at the receiver side. As adaptive modulations, created using spatial diversity (SD) and spatial multiplexing (SMP) modulations, SD/SMP switching, adaptive SMP (aSMP), and SD-assisted adaptive SMP (SD-aSMP) are considered. Analytical and simulation results were obtained for achievable data rates in an indoor environment. Cumulative distribution function (CDF) graphs were used to assess the overall performance based on these data rates. GADR has an advantage over ADR in low SNR regions but performs similarly in high SNR regions. The SD-aSMP scheme demonstrated the best performance across all SNR regions as a hybrid modulation, taking advantage of diversity gain in low SNR and multiplexing gain in high SNR regions. The adaptive SMP schemes benefit from increasing the number of LEDs and increasing the elevation angle up to 60 degrees.

The importance of lifestyle in the prevention and treatment of many chronic diseases is recognized throughout the world, but in real life, insufficient attention is paid to discussing these issues with patients, often due to insufficient knowledge. To fill this gap, many countries are implementing educational programs in lifestyle medicine with certification of specialists, which not only significantly contributes to the improvement of public health, but also reduces economic costs in the healthcare system.
As a component of lifestyle medicine educational programs, a nutrition educational program for senior and mid-level healthcare professionals is presented, which can serve as a model for teamwork in the field of nutrition. A nurse, who has undergone some training, can take her part of the responsibility of working with a patient, relieving the burden of the doctor and maintaining the ethical standards of the relationship with them.
In order to expand the knowledge of doctors in the field of nutrition, reports on the principles of healthy diet among women were presented during 2 conferences, organized by the “Health and Healthcare” NGO in March and May of this year.
All the presented events have received accreditation.

Autism spectrum disorder (ASD) is a developmental disorder characterized by deficits in social interaction and communication, as well as restricted interests and repetitive behaviors. Research suggests that the gut-brain axis plays an important role in the pathogenesis of autism, as the gut microbiota produces short-chain fatty acids that affect microglia in the central nervous system. Increased intestinal permeability can lead to the production of pro-inflammatory endotoxins and activation of the immune system. Problems with the innate immune response, including impaired cytokine production and monocyte function, are common in ASD. Pro-inflammatory cytokines such as IL-1β, IL-6, and TNFα influence neuroinflammation and behavior. Further research is needed to develop effective therapeutic interventions.

Studies of the oral cavity in chronic diffuse liver diseases are of great interest to clinicians, since pathological processes developing in the liver, as a rule, lead to organic and functional disorders in the oral mucosa. It is known that chronic liver diseases cause secondary immunodeficiency, which affects not only the entire body as a whole, but also the condition of the organs and tissues of the oral cavity: mucous membrane, periodontium, and hard tissues of the teeth. Correct and timely assessment of the condition of the oral mucosa and the choice of modern means of rational treatment by the physician are topical issues in dentistry. The aim of the study was to examine the condition of the oral mucosa in patients with HBV infection before and after the complex therapy. 50 patients with HBV infection - 14 women and 36 men aged from 18 to 72 years - were examined before and after the complex therapy. All patients underwent a dental examination, including an external examination of the lips and corners of the mouth, and an assessment of the condition of various parts of the oral cavity. The complex therapy included: local dental, etiotropic therapy and local use of the probiotic “Brefovil”. Thus, based on the obtained results, it can be concluded that after the complex therapy, improvements were observed in the oral mucosa; in particular, when comparatively studying lesions before and after the complex therapy of HBV, it was established that the main symptoms reliably have positive dynamics and are detected with less frequency.

The fight against the adverse effects of bariatric surgery is further complicated by the fact that diseases caused by obesity and bariatric surgery are pathogenetically and clinically related. Despite the fact that modern technologies can reduce the incidence of these complications, unfortunately, the widely used methods of bariatric surgical interventions do not protect the surgeon and the patient from post-operative complications and do not always provide the desired result in the form of stable weight and improved quality of life.
This retrospective case-control study aimed to evaluate the development of complications after standard and modified Laparascopic Sleeve Gastrectomy (LSG) in patients with the Body Mass Index (BMI) > 50 in 24 months after the intervention.
The study included 206 patients, who applied for bariatric surgery at the surgical department of the Shengavit Medical Center and met the inclusion criteria. The patients were divided into 2 groups dependent on the type of LSG performed. The first group (n = 98) included patients, who underwent LSG, using the standard method, and the second group (n = 108) included patients, who underwent modified method of the LSG with appropriate management of the postoperative period.
Comparing our data with the results of studies published in the literature in recent years, we can appreciate the importance of studying the severity of complications of bariatric surgery. In addition, analysis of the results of our study confirms the relatively higher effectiveness of the modified LSG in patients with a BMI > 50 in terms of a comparative reduction in the incidence of post-operative complications.

Endometrial pathology represents a significant component of gynecological morbidity and is frequently implicated in cases of abnormal uterine bleeding, serving as a common indication for intrauterine procedures. Ultrasound examination (US) of the pelvic organs is critical for assessing endometrial status. However, it possesses inherent limitations that can lead to both overdiagnosis and underdiagnosis of conditions. In contrast, hysteroscopy (HS) markedly enhances the diagnostic and therapeutic capabilities concerning endometrial pathologies.
This study conducted a retrospective analysis of 120 medical records of patients presenting with endometrial pathology, utilizing results from transvaginal ultrasound (TVUS). For patients of reproductive age, TVUS was performed during the early proliferative phase, followed by hysteroscopic resection and diagnostic curettage of the uterine cavity, with subsequent histopathological evaluation of the collected specimens.
The findings indicate that TVUS has a lower diagnostic accuracy compared to HS in establishing a definitive diagnosis of intrauterine pathology. Consequently, it is recommended that follow-up TVUS be performed after the subsequent menstrual cycle to prevent unnecessary anesthesia and surgical interventions in reproductive-age patients.

A Ciência, Tecnologia e Inovação (CT&I) é essencial para o desenvolvimento dos países, sendo as universidades um agente estratégico nesse processo. Nas últimas décadas, o Brasil adotou diversas políticas públicas para promover o desenvolvimento científico, tecnológico e de inovação, resultando em avanços importantes, embora ainda haja muito a ser alcançado. Atualmente, as ferramentas utilizadas para avaliar a eficiência das políticas públicas têm ganhado importância, e a Análise Envoltória de Dados (DEA) se destaca para avaliar a eficiência técnica de instituições de ensino superior. Dessa forma, o objetivo dessa pesquisa é analisar a eficiência em CT&I de 45 Universidades Federais, situadas em 19 Unidades da Federação brasileiras, entre 2015 e 2017, utilizando a DEA. As variáveis de entrada adotadas foram recursos humanos e financeiros, enquanto que as variáveis de saída foram publicações de artigos e obtenções de patentes. Os resultados mostraram que 16 universidades (35,56%) foram tecnicamente eficientes, permitindo a identificação das metas a serem alcançadas pelas unidades ineficientes. Uma das principais contribuições desta pesquisa foi a quantificação do nível de melhoria necessário para cada instituição ineficiente, auxiliando-as nas decisões gerenciais e no planejamento das políticas públicas de CT&I no Brasil.
O texto plataformizado
Authors: Dias Cristiane Costa
Published: December 2024

Esse artigo tem como objetivo refletir sobre a problemática do texto como forma material das novas discursividades produzidas pelas tecnologias digitais. Da perspectiva da Análise de Discurso, a noção de texto é considerada como unidade complexa onde se manifesta o discurso. Nesse sentido, questionamos: como o discurso tem sido enformado pelas ferramentas digitais de textualização, produzindo unidade (imaginária) ao discurso? No meu entender, a reflexão sobre texto, hoje, não pode prescindir 1. da reflexão sobre as ferramentas digitais que utilizamos para produzir textos, já que aplicativos como whatsapp, ferramentas de IA, plataformas de redes sociais, dentre outras, fazem parte da produção de sentidos no nosso cotidiano; e 2. da reflexão sobre a plataformização como condição material de produção e reprodução das textualidades, pelas quais os textos se constituem, se formulam e circulam. Dito de outro modo, é preciso considerar que as textualidades são determinadas por um processo histórico e tecnológico que é o da plataformização, na conjuntura política e econômica do “capitalismo de plataforma”, conceito criado por Nick Srnicek (2017) “com vistas a descrever e analisar a sociedade que se encontra cada vez mais mediada, operada, organizada pelas tecnologias digitais, pela extração e processamento de informações e dependência de infraestruturas informacionais.” Nessas condições de produção, as textualidades contemporâneas dão forma aos sentidos. É a partir delas, portanto, que é preciso pensar o texto. Para tanto, tomarei como objeto de análise textualidades em circulação em diferentes plataformas e ferramentas, buscando compreender como, a partir delas, se produz “contorno material” ao dizer.

A Study on How Age Sensitivity Moderates the Learning of New Health Behaviors via Social Media Platforms
Authors: Kituyi Geoffrey Mayoka
Published: December 2024

The objective of this study was to analyze the moderation effect of Age Sensitivity on the relationship between Cognitive Factors and Self-Regulation of social media users in learning new health behaviors via social media platforms in Sub-Sahara Africa.The study adopted a cross-sectional research design where data were collected and analyzed at one point in time. In line with the requirements of cross-sectional design, quantitative research methods were used to collect, analyze and present the findings. Data were analyzed using descriptive statistics, regressions, modegraphs, and confirmatory analysis in structural equation modelling.Results reveal that the moderation effect of Age Sensitivity is high. Inversely, the moderation effect is low when Age Sensitivity is low. Therefore, high Age Sensitivity will influence Cognitive Factors to create high Self-Regulation of social media users in learning new health behaviors via social media platforms in Sub-Sahara Africa. We learn that individuals with strong beliefs become more self-regulated once they become age-sensitive.Given that Self-Regulation positively influences health behavior, we are confident that the moderation effect of Age Sensitivity in the relationship between Cognitive Factors and Self-Regulation results in positive learning. Therefore, it is important for social media developers to enhance the knowledge of their users. At the same time, they should be mindful of users’ beliefs and ages when packaging health-related content. This will promote information acceptance and consumption, thereby helping to change the Health Behaviors of social media users positively.
Deference to the Executive?
Authors: Silke Alexander
Published: December 2024

The book examines the changing approach of courts in reviewing foreign affairs decisions of the executive. Traditionally, the judiciary awarded deference to executive decisions in that area, a notion that clashes with the idea of general judicial oversight in the modern constitutional state. As the problem is often looked at solely from a national angle, this thesis chooses a comparative approach taking into account the development in three democratic countries to identify general trends as well as differences. Thereby, it shows the development of a new judicial approach, which does not per se defer to executive assessments in the field.

Authors: Meisch Claude , Smith Robin J. , Martens Koen
Published: December 2024

We present an updated global checklist of extant non-marine Ostracoda, covering taxonomic changes in the published literature up to 31st December 2023. The checklist is subjective, as apart from published taxonomic changes, also some additional alterations are proposed, including ten candonid tribes which are upgraded to subfamilies, six new combinations, one new name, five synonymies and one new taxonomic placement. The checklist presently includes 2420 accepted species in 295 genera, as well as 84 uncertain species that are too poorly described to be recognisable. We also provide the totals of species numbers for each taxonomic rank, from genera up to order, and numbers of species and endemic species in each of the world’s major zoogeographical regions.
Pulmonary Adenocarcinoma Updates: Histology, Cytology, and Grading
Authors: Sharma Jake , Zhou Fang , Moreira Andre L.
Published: December 2024

Context.—

Adenocarcinomas are the most common histologic subtype of lung cancer, and exist within a widely divergent clinical, radiologic, molecular, and histologic spectrum. There is a strong association between histologic patterns and prognosis that served as the basis for a recently described grading system. As the study of molecular pathology rapidly evolves, all targetable mutations so far have been found in adenocarcinomas, thus requiring accurate diagnosis and classification for triage of molecular alterations and adequate therapy.

Objective.—

To discuss the rationale for adenocarcinoma classifications within the 2021 5th edition of the World Health Organization, with a focus on nonmucinous tumors, including tumor grading and biopsy/cytology diagnosis.

Data Sources.—

PubMed search.

Conclusions.—

A grading system for adenocarcinoma has improved prognostic impact of the classification of pulmonary adenocarcinoma. An accurate diagnosis of adenocarcinoma in small biopsy material is important for tissue triage for molecular studies and ultimately for patient management and treatment.

The Relationship Between Self-Regulation Skills and Anxiety Levels in Preschool-Aged Children
Authors: Öksüz Ayyüce , Çağlar Atila
Published: December 2024

Early childhood is a foundational period in life, during which developmental domains and skills begin to emerge. One of these skills is self-regulation. Self-regulation skills involve the ability of an individual to control their emotional, cognitive, and behavioral characteristics. This study was conducted to examine the relationship between self-regulation skills and anxiety levels in preschool children. To this end, the study focused on the relationship between children's self-regulation skills and anxiety levels, and whether this relationship showed significant differences based on demographic characteristics.
The research was carried out with the parents of 402 children aged 4-6 years who were attending preschool education institutions in the province of Samsun. To measure children's self-regulation skills, the Self-Regulation Skills Scale for 4-6-Year-Olds (Parent Form) was used. To assess the anxiety levels of preschool children, the Preschool Anxiety Scale adapted for 4-6-year-old children was utilized, along with a personal information form created by the researcher for families and children.
For the analysis of research data, statistical techniques such as Pearson Correlation Analysis, MANOVA, ANOVA, and t-tests were employed following a normality assessment. The results of the study revealed a low-level, negative correlation between children's self-regulation skills and anxiety levels. As children's self-regulation skills increased, their anxiety levels decreased, or conversely, as anxiety levels increased, self-regulation skills declined. It was concluded that, in terms of the impact of self-regulation skills on anxiety levels, the other hypotheses did not show a significant difference.
