Religiones rurales durante la Antigüedad Tardía
Authors: Alvar Nuño Antón , Martínez Maza Clelia
Published: December 2021

El estudio de la religiosidad rural en el occidente tardoantiguo ha sido hasta ahora un tema de investigación secundario centrado bien en destacar la existencia de pervivencias paganas en ámbito rural, bien en la propagación del cristianismo desde las estructuras de poder. La intención de este artículo es abrir nuevas perspectivas de análisis que tengan en cuenta la propia idiosincrasia del mundo rural, teniendo en cuenta el espacio y la diversidad de actores que interactúan en el campo de manera dinámica, y no como receptáculos pasivos en la implantación de nuevos horizontes religiosos. Para ello, nuestra perspectiva de análisis se centra principalmente en el estudio de las motivaciones religiosas del rico espectro social del mundo rural: no solo potentes y domini, sino también pequeños propietarios, arrendatarios, jornaleros y esclavos. Al poner el foco en el dinamismo de las experiencias religiosas rurales y demostrar que el entorno afecta a la configuración de los sistemas religiosos, pretendemos enriquecer el debate incluyendo en las cuestiones que se han estudiado hasta ahora la manera en que las motivaciones y expectativas religiosas individuales – determinadas por condicionantes espaciales y por los sistemas de ordenación de las relaciones sociales articulados a partir de los sistemas de producción económica, distribución y consumo en ámbito rural – intervienen en y modifican el mapa religioso local.
La falacia cosmopolita. Una revisión del pensamiento de S. Benhabib
Authors: Crespo Catalán Carmen
Published: December 2021

Las migraciones transnacionales, la integración del pluralismo cultural en los Es-tados de acogida de inmigrantes, el reconocimiento de sus derechos civiles, económicos y políticos y las condiciones de acceso a la ciudadanía son fenómenos de interés público que nos obligan a repensar las fronteras de la democracia y la someten a una renovación continua. La presencia del extranjero irregular y la llegada masiva de refugiados a las puertas de Europa han tambaleado las bases de nuestra ciudadanía, poniendo en tela de juicio los valores comu-nitarios y desafiando la tradición cosmopolita desde el afuera de la Administración de la UE. Estas contradicciones prácticas llevan a los teóricos de la justicia y la filosofía política, como S. Benhabib, a explorar los límites de la pertenencia, la responsabilidad y la ética en las de-mocracias contemporáneas. El objetivo de conciliar los derechos de autogobierno y libre auto-determinación territorial con la afirmación de los derechos humanos universales pasa, nece-sariamente, por argumentar la vigencia del Estado-nación moderno y problematizar las lógicas divisorias de la soberanía territorial, tan reforzada hoy en día.

Inflammation plays an important role in atherosclerotic plaque destabilisation and the development of cardiovascular complications. Suppression of its activity in order to reduce residual inflammatory risk in atherosclerotic cardiovascular diseases remains an urgent and unresolved problem to the date. Over the recent years, evidence of the effectiveness of such an approach in secondary prevention of coronary heart disease has been obtained. The purpose of this review was to analyse modern literature on the effect of anti-inflammatory therapy with colchicine on the prognosis of patients with coronary heart disease. The review was carried out using the search for papers published in the PubMed and ClinicalTrials databases within the period from 2007 to 2021. The search was carried out using the keywords «colchicine», «inflammation», «atherosclerosis», «coronary heart disease» and «acute coronary syndrome». The anti-inflammatory and antiatherogenic effects of colchicine are discussed. The paper presents results of studies devoted to the use of colchicine in chronic and acute coronary syndrome, including the key ones LoDoCo2 (2020) and COLCOT (2019) which provided evidence of the effect of the drug on the disease outcome. The issues of safety and prospects of colchicine application in clinical practice for reduction of the residual inflammatory risk in patients with coronary heart disease are addressed.

Authors:   M. Gorki Donetsk national medical university, Makhmutov R.F.
Published: December 2021

The aim of the research. To evaluate the effectiveness of synthetic low-molecular interferon inducers in children with Epstein-Barr viral infection. Material and methods. The study included 68 children aged 7 to 17 years with primary Epstein-Barr viral infection: 38 children in the main group received basic therapy against the primary form of Epstein-Barr viral infection in age-specific dosages in combination with a synthetic low-molecular interferon inducer; 30 children of the control group received the conventional basic therapy with age-specific dosages. Results. It has been established that clinical manifestation of Epstein-Barr viral infection is based on immunopathological inflammation mediated by the factors of cellular immunity. As a result of the therapy, 78.95 % of children in the main group had a normal rate of functional recovery of the liver. In the control group, however, the recovery was delayed in 60.00 % of children: rapid recovery was only noted in the main group. Administration of synthetic lowmolecular weight interferon inducers in addition to basic symptomatic therapy facilitated the reduction of intoxication symptoms duration by 4.7±1.9 days (p < 0.05) and the duration of the icteric period by 5.3±0.9 days (p < 0.05), as well as 5.1±1.3 days earlier normalisation of liver size (p < 0.05). Conclusion. Thus, the use of synthetic low molecular weight interferon inducers in combination with basic therapy against the primary form of Epstein-Barr viral infection in children contributes to a faster restoration of the functional state of the liver. The conducted clinical and biochemical studies indicate high efficiency of synthetic low molecular weight interferon inducers in the complex therapy of Epstein-Barr viral infection in children.

Aim of study. To study the total level of 25-hydroxyvitamin D in children with SARS-CoV-2 infection (COVID-19). Material and мethods. A total of 82 children aged 0-17 diagnosed with SARS-CoV-2 infection were enrolled. Depending on the severity of clinical symptoms, all children were divided into three groups according to the COVID-19 severity: asymptomatic, mild and moderate. The serum level of vitamin D in all patients was tested via the immunochemical method. Results. It was found that children with SARS-CoV-2 infection had lower serum level of vitamin D (29.92 [22.22; 28.07] ng/ml) as compared with the control group (36.43 [32.05; 44.08] ng/ml; p<0.001). A total of 90% of the children with SARS-CoV-2 infection were diagnosed with insufficiency or deficiency of vitamin D (<30 ng/ml). Only 10 % of the patients had normal levels of vitamin D. The insufficiency of vitamin D was found more often amongst children aged 0-11 and deficiency of total 25-hydroxyvitamin D was more common for children aged 12-17. The difference in serum levels of vitamin D depending on the severity of SARS-CoV-2 infection was not found. Male children with SARS-CoV-2 infection showed lower levels of vitamin D (p=0.013). Conclusion. A total of 90 % of the children with SARS-CoV-2 infection had insufficiency or deficiency of vitamin D regardless of the severity of clinical symptoms.

Urinary stone disease (urolithiasis, UL) is one of the most prevalent diseases in the world affecting almost 3% of the population, mainly people of working age from 40 to 50 years, which determines the relevance of a comprehensive study of this disease. Meanwhile, few works devoted to the interrelation between UL and renal abnormalities have been published. The unusual nature of angioarchitectonics, location, shape, structure, number of kidneys and upper urinary tract make it difficult to perform both open and endoscopic surgery thus preconditioning the reduction of their effectiveness and increasing the number of complications. In recent years, the number of indications for open stone surgery has significantly decreased. Percutaneous surgery has become widely used in endourology, including treatment of abnormal kidneys. However, the issues of percutaneous nephrolitolapaxy (PCNL) in kidney abnormalities have not been completely resolved yet. The article presents a clinical case of successful percutaneous nephrolitolapaxy of complete coral-shaped kidney stone (Class 4) in a patient with lumbar renal dystopia.

Published: December 2021

Dos pacientes acudieron al departamento de Endodoncia para evaluar las piezas dentarias 35 y 46. Ambas piezas tenían antecedente de colocación de poste en un tratamiento endodóntico reciente en la pieza 46, y hacía 3 meses en la pieza 35, con perforaciones de gran tamaño, evidentes en el tercio medio radicular. En ambos casos se recomendó el sellado de perforaciones. Se retiraron los postes y se colocó MTA Angelus blanco (Angelus, Londrina, PR, Brasil) en las perforaciones de ambos casos. Finalmente, los conductos radiculares se obturaron utilizando la técnica de onda continua. Los controles de 6 meses, 2 años y 6 años (pieza 35) y los controles de 3 meses, 1 año y 3 años (pieza 46) mostraron una evolución favorable. Se puede concluir que la aplicación de MTA en perforaciones iatrogénicas promueve buenos resultados, permitiendo el mantenimiento de los dientes en función dentro de la cavidad oral.

В статті досліджуються найважливіші тенденції у вивченні господарської реформи у СРСР 1965 р. західними науковцями. Автором визначені досягнення, головні ідеї та особливості західного історіописання проблеми. Західні науковці присвятили цій реформі чимало досліджень і коментарів, що цілком зрозуміло як з точки зору завдань, що стояли перед західною радянологією в той період, так і з урахуванням тих очікувань, які породила ця реформа в нашій країні та за її межами в перші роки її здійснення. Увага зарубіжних економістів до господарської реформи 1965 р. значною мірою виправдовувалася і тим, що на її прикладі можна було вивчити фундаментальні проблеми, пов’язані з функціонуванням економіки радянського типу, дати відповідь на питання про можливість «мирного співіснування» елементів централізації і децентралізації в радянській економічній системі.

Після виведення своїх військ з Афганістану СРСР підтримував режим НДПА в афганській кризі. На противагу усталеній в радянській та російській історіографії думці ми вважаємо, що Радянський Союз надалі лишався стороною конфлікту. Головними складовими політики СРСР щодо Афганістану в нових умовах були інститут військових радників, який було збережено, та широкомасштабні поставки зброї й військової техніки. Це призвело до ескалації афганської кризи, а також подальшого виснаження економіки CРСР в останні роки його існування.

Published: December 2021

El estudio tiene como objetivo analizar el currículo del Programa de Educación Secundaria Técnica Básica Agrícola (PESTBA) en relación a los factores que inciden en el aprendizaje agrícola ambiental en México. Se utilizó una metodologí de análisis de contenido cualitativo donde la deducción e inducción constituyeron la base fundamental de las interpretaciones que a partir de elementos conceptuales medio ambientales permitiendo el análisis de la educación agrícola. Los componentes estructurales propuestos del PESTBA sirvieron para el proceso de categorización y análisis de la información empírica son: conocimiento tecnológico, técnica y naturaleza y participación tecnológica. Entre los resultados se llegó a comprender que los factores institucionales prevalecientes generan aprendizajes fragmentados y no se alcanza una educación secundaria técnica básica agrícola que ayude a revertir el deterioro ambiental. A manera de propuesta es importante la gestión permanente de una educación en los distintos niveles y modalidades, definida desde y para el ambiente en los contenidos curriculares. En el caso particular de los jóvenes estudiantes de Sonora, México, la vía para alcanzar lo anterior es una didáctica sociocultural situada centrada en aprehender el mundo y reflexionar ante las situaciones inmediatas y mediatas del devenir social y ambiental que amenazan la seguridad del planeta.
Welfare Assessment Tools in Zoos: From Theory to Practice
Authors: Jones Narelle , Sherwen Sally , Robbins Rachel , McLelland David , Whittaker Alexandra
Published: December 2021

Zoos are increasingly putting in place formalized animal welfare assessment programs to allow monitoring of welfare over time, as well as to aid in resource prioritization. These programs tend to rely on assessment tools that incorporate resource-based and observational animal- focused measures since it is rarely feasible to obtain measures of physiology in zoo-housed animals. A range of assessment tools are available which commonly have a basis in the Five Domains framework. A comprehensive review of the literature was conducted to bring together recent studies examining welfare assessment methods in zoo animals. A summary of these methods is provided with advantages and limitations of the approach es presented. We then highlight practical considerations with respect to implementation of these tools into practice, for example scoring schemes, weighting of criteria, and innate animal factors for consideration. It is concluded that would be value in standardizing guidelines for development of welfare assessment tools since zoo accreditation bodies rarely prescribe these. There is also a need to develop taxon or species- specific assessment tools to inform welfare management.

Published: December 2021

Rheumatoid arthritis (RA) is a chronic autoimmune disease associated with a significantly increased risk of cardiovascular mortality, mainly attributed to accelerated atherosclerosis. Methods: Thirty-two women (aged more than 18 years) with RA, and 25 age-matched healthy women were included in this study. Biomarkers of inflammation, red blood cells (RBCs) redox balance, estrogen receptor alpha (ER-α) expression as well as ERK 1/2 phosphorylation content were evaluated in RA patients at baseline and six months after treatment with disease modifying anti‐rheumatic drugs (DMARDs). Results: For the first times we demonstrated that in RA patients: i) disease activity score (DAS-28) positively correlated with RBC ER-α expression, and negatively with total antioxidant capacity of plasma; ii) RBC ER-α expression positively correlated with systemic inflammatory biomarkers and oxidative stress parameters as well as ERK 1/2 phosphorylation; and iii) DMARDs treatments improved the clinical condition measured by DAS-28 score decrease, although the RBCs appeared to be more prone to pro-oxidant status associated to the expression of survival molecules. Conclusion: Our data strongly suggest that RBCs could also participate in vascular homeostasis through fine modulation of an intracellular signal linked to the ER-α.
Inhomogeneous Phases in the Chirally Imbalanced 2+1-Dimensional Gross-Neveu Model and Their Absence in the Continuum Limit
Authors: Pannullo Laurin , Wagner Marc , Winstel Marc
Published: December 2021

We study the μ-μ45-T phase diagram of the 2+1-dimensional Gross-Neveu model, where μ denotes the ordinary chemical potential, μ45 the chiral chemical potential and T the temperature. We use the mean-field approximation and two different lattice regularizations with naive chiral fermions. An inhomogeneous phase at finite lattice spacing is found for one of the two regularizations. Our results suggest that there is no inhomogeneous phase in the continuum limit. We show that a chiral chemical potential is equivalent to an isospin chemical potential. Thus, all results presented in this work can also be interpreted in the context of isospin imbalance.
Tracking of Melanoma Cell Plasticity by Transcriptional Reporters
Authors: Vidal Anna , Redmer Torben
Published: December 2021

Clonal evolution and cellular plasticity are the genetic and non-genetic driving forces of tumor heterogeneity that in turn determines the tumor cell response towards therapeutic drugs. Sever-al lines of evidence suggest that therapeutic interventions foster the selection of drug resistant neural crest stem-like cells (NCSCs) that establish minimal residual disease (MRD) in melano-ma. Here we established a dual reporter system enabling the tracking of NGFR expression and mRNA stability, providing insights into the maintenance of NCSC-states. We observed that the transcriptional reporter that contained a 1kb fragment of the human NGFR promoter was acti-vated only in a minor subset (0.72±0.49%, range 0.3-1.5) and ~2-4% of A375 melanoma cells re-vealed stable NGFR mRNA. The combination of both reporters provided insights into pheno-type switching and revealed that both cellular subsets gave rise to cellular heterogeneity. Moreover, whole transcriptome profiling and gene set enrichment analysis (GSEA) of the minor cellular subset revealed hypoxia-associated genes serving as potential drivers of a NGFR-associated phenotype switching in vitro and in relapsed, post-BRAF inhibitor treated tu-mors. Concordantly, we observed that the minor cellular subset increased in response to dabrafenib over time. In summary, our reporter-based approach provided insights into plastici-ty and identified a cellular subset that might be responsible for the establishment of MRD in melanoma.
Adapting Traditional Healing Values and Beliefs Into Therapeutic Cultural Environments for Health and Well-Being
Authors: Marques Bruno , Freeman Claire , Carter Lyn
Published: December 2021

Although research has long established that the interaction with the natural environment is associated with better overall health and well-being outcomes, the Western model mainly focuses on treating the symptoms. In Aotearoa-New Zealand, the Indigenous Māori have long demonstrated significantly more negative health outcomes than non-Māori. Little research has examined the causes compared to Western populations or the role of the natural environment in health outcomes for Māori. An exploration of rongoā Māori (traditional healing system) was conducted to ascertain the importance of landscape in the process of healing. Eight rongoā healers or practitioners took part in semi-structured narrative interviews from June to November 2020. Transcribed interviews were analysed using an interpretative phenomenological analysis and Kaupapa Māori techniques. The findings show how rongoā is underpinned by a complex set of cultural values and beliefs, drawing from the connection to wairua (spirit), tinana (body), tikanga and whakaora (customs and healing), rākau (plants), whenua (landscape) and whānau (family). Incorporating such constructs into the landscape can foster our understanding of health and well-being and its implications for conceptualising therapeutic environments and a culturally appropriate model of care for Māori and non-Māori communities.

Field robotics has been undergoing rapid progress in recent years. It addresses a wide range of activities performed in outdoor environments, and its applications are being developed in areas where it was previously considered difficult to apply. This rapid progress is largely supported by AI-based improvements in computer vision systems with monocular cameras, stereo cameras, RGB-D cameras, LiDAR systems, and/or other sensors. Field robotics is impelled by an application-driven approach by its nature, and it contributes to the resolution of social problems and the creation of new innovations, including autonomous driving to reduce casualties, autonomous working machines/robots to resolve the problems of labor shortages or dangers, disaster-response robots to aid rescue parties, various kinds of aerial robots to do searches or make deliveries, underwater robots to perform search missions, etc.

In this special issue on “Field Robotics with Vision Systems,” we highlight sixteen interesting papers, including one review paper, fourteen research papers, and one development report. They cover various application areas, ranging from underwater to space environments, and they propose interesting integration methods or element technologies to use in outdoor environments where vision systems and robot systems have great difficulty performing robustly.

We thank all authors and reviewers, and we hope that this special issue contributes to future research and development in area of field robotics, which promises new innovations.

Published: December 2021

In this study, we developed a system for calculating the relative position and angle between a mobile robot and a marker using information such as the size of the marker of the internal camera of the mobile robot. Using this information, the mobile robot runs autonomously along the path given by the placement of the marker. In addition, we provide a control system that can follow a trajectory using information obtained by recognizing the mobile robot when reflected in an external camera using deep learning. The proposed method can easily achieve autonomous path travel control for mobile robots in environments where GPS cannot be received. The effectiveness of the proposed system is demonstrated under several actual experiments.
CNN-Based Terrain Classification with Moisture Content Using RGB-IR Images
Authors: Goto Tomoya ,   Keio University 3-14-1 Hiyoshi, Kohoku-ku, Yokohama, Kanagawa 223-8522, Japan, Ishigami Genya
Published: December 2021

Unmanned mobile robots in rough terrains are a key technology for achieving smart agriculture and smart construction. The mobility performance of robots highly depends on the moisture content of soil, and past few studies have focused on terrain classification using moisture content. In this study, we demonstrate a convolutional neural network-based terrain classification method using RGB-infrared (IR) images. The method first classifies soil types and then categorizes the moisture content of the terrain. A three-step image preprocessing for RGB-IR images is also integrated into the method that is applicable to an actual environment. An experimental study of the terrain classification confirmed that the proposed method achieved an accuracy of more than 99% in classifying the soil type. Furthermore, the classification accuracy of the moisture content was approximately 69% for pumice and 100% for dark soil. The proposed method can be useful for different scenarios, such as small-scale agriculture with mobile robots, smart agriculture for monitoring the moisture content, and earthworks in small areas.

This paper describes the development of a robust object tracking system that combines detection methods based on image processing and machine learning for automatic construction machine tracking cameras at unmanned construction sites. In recent years, unmanned construction technology has been developed to prevent secondary disasters from harming workers in hazardous areas. There are surveillance cameras on disaster sites that monitor the environment and movements of construction machines. By watching footage from the surveillance cameras, machine operators can control the construction machines from a safe remote site. However, to control surveillance cameras to follow the target machines, camera operators are also required to work next to machine operators. To improve efficiency, an automatic tracking camera system for construction machines is required. We propose a robust and scalable object tracking system and robust object detection algorithm, and present an accurate and robust tracking system for construction machines by integrating these two methods. Our proposed image-processing algorithm is able to continue tracking for a longer period than previous methods, and the proposed object detection method using machine learning detects machines robustly by focusing on their component parts of the target objects. Evaluations in real-world field scenarios demonstrate that our methods are more accurate and robust than existing off-the-shelf object tracking algorithms while maintaining practical real-time processing performance.

In this work, the chemical and phase compositions of the studied slag were analyzed, and a differential thermal analysis of its sample was carried out. Converter slag was added to the composition of the masses in an amount of 2.5 to 30 wt%, the rest was glass cullet. Вurning of the samples was carried out in the temperature range of 850-925 ° C. For the samples under study, using a sand volumetric meter, the volume was determined and the swelling coefficient was calculated, the compressive strength was determined, and the type of structure, which depends on the average diameter of the prevailing pores, was analyzed. The dependence of the swelling coefficient of the investigated materials on the burdening composition and burning temperature has been established. To obtain porous materials with a swelling coefficient of 2.16-2.67 and uniform fine-porous structure (predominant pore size less than 0.5 mm), it is optimal to introduce converter slag into the composition of the masses in an amount of 10-15 wt%, and the recommended temperature range their burning 850-900 ° C. Analysis of the phase composition of the materials obtained indicates the presence of wollastonite as the main crystalline phase, which, due to the acicular structure of the crystals, has a reinforcing effect and contributes to an increase in strength characteristics. The developed porous glass-crystalline materials can be used as thermal insulation and aggregates in lightweight concrete.

Recently published reviews articles and some original electronic based data collected researched articles have shown that diabetes mellitus (DM) has increased the chance of prevalence of tuberculosis (TB) in adults especially in the under developed countries where there is already epidemics of the TB disease exist. These findings are still hypothesis and are not supported by logical findings. DM gave birth to TB or vice versa is a debate which needs some better research work to document this fact. This mini critical review article will emphasize on some pharmacological, physiological and clinical aspects of both the diseases to show the connection of both diseases.

Despite a significant amount of work in the field of mechanically doped alloys and, above all, based on aluminum and copper, research aimed at creating mechanically doped alloys is extremely limited. In this regard, the following work aimed at to establishing the regularities of the formation of the phase composition, structure, and properties in the implementation of the technology for obtaining mechanically doped heat‑resistant steels, is important and relevant.

The basis for the development of mechanically doped alloys were the results of long‑term research carried out at the Belarusian‑Russian University and aimed at studying mechanically and thermally activated structural phase transformations taking place at all the technological stages of obtaining mechanically doped metal alloys. In this article, in a generalized form the final research results are presented, revealing the patterns of these transformations, which are a reliable scientific basis for the creation of mechanically doped complex‑hardened heat‑resistant steels.

The established regularities of the formation of powders based on iron and nickel, obtained by the method of mechanical alloying and intended for the deposition of thermal spraying coatings, as well as the manufacture of products by layer‑by‑layer synthesis. The structure, phase composition and properties of materials are investigated. Powders consist of particles with a size of 20–70 microns, differ in the submicrocrystalline type structures, and nonequilibrium phase composition. Thermal spray coatings made of them have a set of properties that significantly exceed the properties of coatings made of commercially available materials. The diameter of the grains of the material obtained by the SLМ method from the synthesized powder is 1.5–2.0 times smaller than that produced from the powder of 316L steel, and the heat resistance is higher.

Cloud Computing is a mass platform to serve high volume data from multi-devices and numerous technologies. Cloud tenants have a high demand to access their data faster without any disruptions. Therefore, cloud providers are struggling to ensure every individual data is secured and always accessible. Hence, an appropriate replication strategy capable of selecting essential data is required in cloud replication environments as the solution. This paper proposed a Crucial File Selection Strategy (CFSS) to address poor response time in a cloud replication environment. A cloud simulator called CloudSim is used to conduct the necessary experiments, and results are presented to evidence the enhancement on replication performance. The obtained analytical graphs are discussed thoroughly, and apparently, the proposed CFSS algorithm outperformed another existing algorithm with a 10.47% improvement in average response time for multiple jobs per round.

Video streaming is widely available nowadays. Moreover, since the pandemic hit all across the globe, many people stayed home and used streaming services for news, education,  and entertainment. However,   when streaming in session, user Quality of Experience (QoE) is unsatisfied with the video content selection while streaming on smartphone devices. Users are often irritated by unpredictable video quality format displays on their smartphone devices. In this paper, we proposed a framework video selection scheme that targets to increase QoE user satisfaction. We used a video content selection algorithm to map the video selection that satisfies the user the most regarding streaming quality. Video Content Selection (VCS) are classified into video attributes groups. The level of VCS streaming will gradually decrease to consider the least video selection that users will not accept depending on video quality. To evaluate the satisfaction level, we used the Mean Opinion Score (MOS) to measure the adaptability of user acceptance towards video streaming quality. The final results show that the proposed algorithm shows that the user satisfies the video selection, by altering the video attributes.
An Experimental Study of the Server-based Unfairness Solutions for the Cross-Protocol Scenario of Adaptive Streaming over HTTP/3 and HTTP/2

Published: December 2021

Since the introduction of the HTTP/3, research has focused on evaluating its influences on the existing adaptive streaming over HTTP (HAS). Among these research, due to irrelevant transport protocols, the cross-protocol unfairness between the HAS over HTTP/3 (HAS/3) and HAS over HTTP/2 (HAS/2) has caught considerable attention. It has been found that the HAS/3 clients tend to request higher bitrates than the HAS/2 clients because the transport QUIC obtains higher bandwidth for its HAS/3 clients than the TCP for its HAS/2 clients. As the problem originates from the transport layer, it is likely that the server-based unfairness solutions can help the clients overcome such a problem. Therefore, in this paper, an experimental study of the server-based unfairness solutions for the cross-protocol scenario of the HAS/3 and HAS/2 is conducted. The results show that, while the bitrate guidance solution fails to help the clients achieve fairness, the bandwidth allocation solution provides superior performance.

The polycystic ovary syndrome is an endocrine condition. One of the leading causes of female infertility and the most common disorder among women. The work was being carried out on 100 Iraqi women (50 cases confirmed with PCOS and 50 controls). Between October 2019 and March 2020, blood samples were collected from the Advanced Institute of Infertility Diagnosis and Assisted Reproductive Technology at AL-Nahrain University and a private laboratory. ELISA was used to evaluate the biochemical parameters of preptin, FSH, insulin, LH, and CCL 18 in serum samples from the AFIAS-6 (AFIAS Automated Immunoassay System). The findings of the analysis indicate that, as opposed to the control group, values of prolactin (ng/ml), LH (mIU/ml), Preptin (pg/ml) and CCL 18 (ng/ml) Quite higher in PCOS sickness (p < 0.001) Compared with the patient group, the values of testosterone (ng/ml) and FSH (mIU/ml) was noticeably higher (p <0.05), and PRLR gene expression levels in PCOS patients were significantly increased by 3.6 times. I n summary, the levels of Preptin and CCL18 can be regarded as PCOS markers.
Логика в онтологии процессов
Authors: Shalack Vladimir I.
Published: December 2021

Целью работы является исследование языковых средств, которые могут быть использованы для проведения рассуждений о процессуальной онтологии, которая отличается от субстанциальной более сложной структурой элементарных “кирпичиков”, лежащих в ее основе. Следствием этого является необходимость использовать языки с более богатыми выразительными возможностями, чем язык классической логики. В работе рассматриваются языки с унарными и бинарными модальностями. Отдельные процессы можно анализировать с двух точек зрения – статики и динамики. В первом случае нас интересуют высказывания, истинность которых зависит лишь от внутренней структуры текущего процесса. Отношение деления процессов позволяет определить на его частях транзитивный, плотный линейный порядок без первого и последнего элементов, который можно понимать, как локальный временной порядок данного процесса. Это, в свою очередь, позволяет говорить о начале процессов, их протекании и окончании. Появляется возможность определить понятия состояния процесса и процесса, как события. Включение в язык бинарной модальности типа некоммутативной конъюнкции позволяет определить аналог причинно-подобной условной связи между частями процесса. Динамика процессов подразумевает возможность их продолжения за пределы текущего процесса. Это может происходить либо благодаря имплицитным причинным связям, когда текущий процесс содержит в себе причину своего будущего продолжения, либо в результате действий активных агентов, которые сами формируют это продолжение. Для представления динамики процессов, как следствия действий активных агентов, использован упрощенный вариант языка динамической логики. Также показано, каким образом можно учитывать цели, которые ставят перед собой активные агенты при выполнении тех или иных действий.
