MR görüntülemede kartezyen olmayan yörüngelerle K-Uzayının 3 boyutlu örneklenmesi
Authors: Dündar Mehmet Sait , Yılmaz Bülent
Published: November 2024

Çağdaş Manyetik Rezonans Görüntüleme (MRG) tekniklerinde, veri akuzisyonu genellikle iki boyutlu kartezyen örnekleme ile gerçekleştirilmektedir. Ancak, bu örnekleme yöntemi, kesitler arasında boşluklar gibi bazı sorunlara neden olabilmektedir. Üç boyutlu akuzisyon, Radyo Frekansı (RF) pulsu ile görüntülenecek olan tüm hacmin uyarılmasını ve elde edilen sinyallerin üç boyutlu k-uzayına örneklenmesini kapsamaktadır. Bu örnekleme yöntemi, kartezyen koordinatlara sahip olabileceği gibi, zaman açısından daha verimli olduğundan genellikle kartezyen olmayan yörüngelerle de gerçekleştirilmektedir.

Bu araştırmada, kartezyen olmayan iç içe kabuk yörüngeleri kullanılarak üç boyutlu k-uzayını örnekleyen yenilikçi bir MR sekansı geliştirilmiştir. Bu örnekleme yöntemi, farklı yarıçaplı 32 adet iç içe kabuktan oluşmakta ve veri akuzisyon hızını artırmak için az-örnekleme tekniği de uygulanmaktadır. Geliştirilen MR sekansı, aynı merkezli kabukların oluşturduğu iç içe yapı ile üç boyutlu k-uzayını etkin bir şekilde doldurabilme yeteneğine sahiptir. Bu sekans, MRG simülasyonlarına tabi tutularak başarılı bir şekilde test edilmiştir. Sonuç olarak, geliştirilen sekansın, üç boyutlu akuzisyonu bir saniyeden daha kısa sürede tamamlayarak k-uzayını doldurabilme kabiliyetine sahip olduğu gösterilmiştir. Bu bulgular, MRG alanındaki mevcut uygulamalara yenilikçi bir alternatif sunmakta ve bu alandaki araştırmaları ileriye taşımaktadır.
Epidemiology, pathophysiology and clinical relevance of the most prevalent valvular heart diseases
Authors: Orsini Enrico
Published: November 2024

The prevalence of valvular heart diseases is 2.5-3% in the general population, but increases exponentially with age, reaching 13- 14% in individuals over 75 years old. Valvular heart diseases are therefore to be considered a disease of old age, so that their incidence has been steadily increasing in recent decades, due to the ageing of the population. Males and females are equally affected, but females are often underdiagnosed and therefore undertreated, as is the case in other areas of cardiovascular diseases. In Western world, degenerative aetiologies have almost completely replaced rheumatic disease, so that mitral stenosis is now very rare in developed countries. In declining order, mitral insufficiency, aortic stenosis and aortic insufficiency are the most prevalent valvulopathies, as revealed by population studies. Despite therapeutic advances, in particular by means of percutaneous intervention techniques, mortality attributable to valvulopathies remains high and progressively increasing, particularly for aortic stenosis. Valvular heart diseases represent excellent models for studying cardiac haemodynamics and pathophysiology. Some of them, in fact, such as mitral insufficiency, exert a volume overload on the heart; others, such as aortic stenosis, a pressure overload, and others, finally, a simultaneous volume and pressure overload, such as aortic insufficiency. Knowledge of the pathogenesis, pathophysiology and haemodynamics of each valve defect appears essential for establishing an optimal diagnostic and therapeutic approach.

Direito da saúde: definição e integração transversal no projeto pedagógico dos cursos de Direito
Authors: Lamy Marcelo
Published: November 2024

Objectives: To identify the conceptual core of Health Law and its scientific autonomy and, based on these ideas, propose a guideline for the integration of its contents in Bachelor of Laws courses. Methodology: The construction of theoretical paradigms was based on bibliographic research submitted to narrative review, guided by synoptic reading; while the integrative proposal was based on documentary research and the researchers' lived experience. Results: The rights and duties related to health, which are the object of Health Law, are expanded by the perception that health does not only result from specific conducts and actions of the doctor-patient relationship, but also from conducts related to the determinants. On the other hand, there is a normative framework that requires the transversal insertion of health issues, by requiring, in Brazil, the transversal treatment of the environmental health theme. Conclusions: Health Law, due to the continued and permanent development of the concepts of health and the right to health and the establishment of a system aimed at embracing all dimensions of these concepts, preserving the epidemiological bias, must embrace the new social, economic and political facets of the right to health. These new facets reveal such a broad scope for this branch of knowledge that it is possible to design the integration of its theme in all traditional curricular units of the bachelor’s degree in law and, thus, comply with the current normative determination.

Green Monetary Policy Measures and Central Bank Mandates: A Comparative Political Economy Analysis
Authors: Matos Rosa Susana
Published: November 2024

Climate change and the political pressure for urgent policy responses have stirred an intense debate as to whether central banks should adjust their monetary policy frameworks in support of the transition to a greener economy. Despite the seriousness of environmental issues and the seeming existence of monetary policy tools to address them, some economists and central bank officials argue that monetary authorities cannot, or should not, be responsible for making policies that act upon the source of those problems. Among other reasons, the adoption of green monetary policy measures can conflict with the primary monetary policy goals, compromise the political independence of central banks, and raise questions about the legitimacy and increased power of some of these banks. Yet, evidence shows that a number of monetary authorities have already adopted environmental criteria in their policymaking, resulting in an expansion of monetary policy toolkits and areas of responsibility. This article undertakes a comparative political economy analysis of the green monetary policy measures and legal mandates of 20 central banks, covering the period between January 2010 and January 2024. This article then examines the monetary policy decisions of two case study central banks, whose green strategies appear not to be fully aligned with their mandates. The empirical findings aim to contribute to the growing political economy literature and international debate on how central banks address pressures related to environmental concerns which, although vital to society and the planet, may pose challenges to conventional goals and established mandates.

Fear of job displacement in the Artificial Intelligence (AI) era echoes long-standing concerns about machines replacing human work. This paper critically examines dominant narratives around AI and its impact on jobs, challenging technology-deterministic predictions of widespread job loss. We introduce two key concepts: the 'reinstatement effect,' which suggests AI can create new jobs by generating demand for new activities, and 'human-technology augmentation,' which emphasizes AI’s potential to enhance human capabilities. Together, these perspectives provide a comprehensive view of AI’s influence on jobs. At the core of our argument is the focus on social good and the importance of regulation in shaping AI’s future impact on jobs.

Basic waveguide structures in anisotropic monocrystalline silicon medium are investigated for the existence of localized acoustic modes. The geometries of the structures were determined by technological methods and the practice of anisotropic etching, which guarantees reproducible high-quality structures in terms of geometric and crystallographic parameters. The acoustic effects were modeled by semi-analytical finite element method in the problems on eigenvalues and on the response to a harmonic traction source. Edge and surface localized modes were found. The spectral composition of the localized modes was interpreted on the basis of the surface acoustic wave slowness curves. Pseudomodes, highly localized leakage waves, were detected in a number of considered structures. The obtained results allow to evaluate promising geometrical configurations for further detailed study of the complete scope of dispersion properties of both single waveguides and their finite set.

The gap width influence between the resonator electrodes with a lateral electric field on its characteristics was experimentally investigated. The resonator represented a plate made of ceramics PZT-19 with shear dimensions of ~ 20×18 mm2. One side of the plate was covered with a film of aluminum with a gap in the center, the width of which was changed wide range. The thickness of the plate was 3.07, 2.38 and 1.9 mm. The frequency dependences of the real and imaginary parts of the electric impedance and admittance were measured, which showed the presence of three resonances in the ranges 63-73 kHz, 75-83 kHz and 91-113 kHz. It is shown that an increase in the gap width leads to an increase in the frequency of parallel and series resonances and to an increase in the maximum value of the real part of the electrical impedance. At the same time, the maximum value of the real part of the electrical admittance decreases for the first and third resonances, and increases for the second one. It was also established that with an increase in the width of the gap, the electromechanical coupling coefficient increases, reaches the maximum and then decreases for the first and third resonances. For the second resonance, the electromechanical coupling coefficient is monotonously increasing with an increase in the gap width.

The work is dedicated to the study of the peculiarities of spin wave dispersion in metallic magnetic nanostructures of heavy metal/ferromagnet based on PtCo compounds using Mandelstam-Brillouin light scattering techniques. Structural and magnetic characterization of the obtained thin-film nanostructures has been conducted and estimates of the magnitude of the Dzyaloshinskii-Moriya antisymmetric exchange interaction have been made for samples with different magnetic layer parameters. It has been shown that the introduction of an atomically ordered layer of PtCo alloy into the nanostructure allows for effective modeling of the Dzyaloshinskii-Moriya interaction strength, as well as the width of the spin-wave resonance line as shown from the Brillouin light scattering spectra. The results can be utilized for the creation of thin-film materials promising for research either in the fields of magnonics or topological magnetism.

The paper experimentally studies and theoretically substantiates the conditions and features of generation of undamped thermal waves during water cavitation, which are associated with the features of the relaxation processes of such waves in the air. The minimum frequency of such waves at normal pressure and air temperature corresponds to 70-80 MHz. It is shown that the interaction of a traveling thermal wave in the air with the front surface of a metal screen leads to the formation of strong acoustic waves in its volume. In the experiments, samples of deuterated titanium removed and shielded by a metal plate, in which the concentration of deuterium was 1.5 times higher than the concentration of basic titanium nuclei, were exposed to high-frequency thermal waves. The states of deuterium nuclei located in a potential well in the titanium lattice as a result of this impact were studied.

Published: November 2024

When modeling seismic processes in heterogeneous media, problems associated with the multi scales of the effects under consideration often arise. Thus, the sizes of geological heterogeneities can be units and tens of meters, while the size of the computational domain can reach units and tens of kilometers. When discretizing the computational domain with a grid with a constant step, problems associated with the size of the occupied memory and the calculation time may arise. In this paper, an algorithm is proposed that uses hierarchical computational grids and a grid-characteristic method for carrying out such calculations. Using the example of a response from a fractured layer, a significant reduction in the calculation time is shown when using the proposed approach.

В работе анализируется синтез наночастиц оксидов железа с использованием силикагелей SiO2·9H2O разной пористости в качестве реакционного сосуда. Исследовано влияние размеров пор используемых силикагелей SiO2·9H2O на процессы, протекающие на всех стадиях синтеза нанокатализаторов – наночастиц оксида железа, проводимого непосредственно в порах силикагеля. Все стадии синтеза исследованы с помощью дифракции рентгеновского излучения и мёссбауэровской спектроскопии. Выявлено, что в порах разных размеров возникают распределения наночастиц оксидов железа по размерам. Эти распределения расширяются при отжигах в процессе синтеза. Кроме того, ширина этих распределений зависит от размера пор. Методом адсорбции-десорбции азота было обнаружено, что поры сами по себе имеют распределение по размерам вокруг заявленных производителем силикагеля размеров пор. Найдена корреляция между распределением наночастиц оксидов железа по размерам и распределениями размеров пор силикагеля.

Экспериментально изучены и теоретически обоснованы условия, а также особенности генерации незатухающих тепловых волн при кавитации воды, которые связаны с особенностями процессов релаксации таких волн в воздухе. Минимальная частота таких волн при нормальном давлении и температуре воздуха соответствует 70-80 МГц. Показано, что взаимодействие бегущей тепловой волны в воздухе с лицевой поверхностью металлического экрана приводит к формированию сильных акустических волн в его объеме. В экспериментах удаленные и экранированные металлической пластиной образцы дейтерированного титана, в которых концентрация дейтерия в 1.5 раза превышала концентрацию базовых ядер титана, подвергались воздействию высокочастотных тепловых волн. Изучены состояния ядер дейтерия, находящихся в потенциальной яме в решетке титана в результате данного воздействия.

Percepción de estudiantes y docentes de la Universidad del Cono Sur de las Américas (UCSA), sobre los estereotipos de género
Authors: Gómez Emilia , Velázquez Graciela
Published: November 2024

En relación a las políticas de género, la Constitución Nacional del año 1992 en Paraguay, manda garantizar la igualdad de derechos y la no discriminación, estableciendo explícitamente la igualdad de las personas, la igualdad de derecho entre mujeres y hombres y la no discriminación, disponiendo que el Estado debe promover las condiciones y crear los mecanismos adecuados. La Universidad del Cono Sur de las Américas (UCSA), es parte del Pacto Global por el Desarrollo Sostenible en el Paraguay, y trabaja en forma activa en formar a estudiantes en ODS para que constituyan una masa crítica consciente de la importancia de trabajar de manera socialmente responsable en pos del desarrollo sostenible, por dicho motivo se llevó a cabo este estudio para determinar la percepción de los estudiantes y docentes de UCSA sobre la igualdad de género y la discriminación en Paraguay en el año 2022. En el análisis de los resultados del estudio, de los 116 participantes, el 55,3% fueron del sexo femenino; con edades comprendidas entre 17 y 65 años; el 81% estaba trabajando. En las respuestas del tipo de trabajo, el 76,4% correspondía al área privada, y de estos el 36,8% de origen familiar. Los resultados asociados al estereotipo femenino observados en el presente estudio son: persona sensible, débil, intuitiva, dependiente, adaptable, fuerte, expresiva, frágil, con autocontrol y complaciente. Los estereotipos de género con mayor puntaje referidos a los hombres observados en el presente estudio son: las que consideran a las personas como proveedora, dominante, independiente, frívola e intrépida. Sin embargo, los estereotipos de género masculino tradicionales, como persona fuerte, con autocontrol, inteligente y racional, se han encontrado referidos a las mujeres en el presente estudio. A fin de superar la desigualdad y la discriminación entre hombres y mujeres, que persisten hasta hoy día, a pesar de lo estampado en la misma Constitución Nacional, en Leyes, Congresos Nacionales e Internacionales. Es necesario realizar estudios referidos al tema, en los distintos niveles de la educación y establecer programas educativos, solo la educación podrá revertir en menor tiempo esta problemática, y no esperar 50 años para que se produzcan cambios, como lo profetizan algunos estudiosos, logrando cambios en el desarrollo social y económico del país en el menor tiempo posible.
A Delaunay Triangulation-Based Low-Poly Image Abstraction
Authors: Joseph Philumon , Kovoor Binsu C. , Thomas Job
Published: November 2024

Low-poly image abstraction is a technique in
which an image is represented using a minimal number of
polygons (typically triangles). Though it is typical that the
image quality reduces while adapting to such a
representation, the research in this direction tries to
maintain the balance between quality and the number of
polygons used in the abstraction. In this paper, we introduce
a novel Delaunay triangulation-based framework, which,
relying on a two-stage process, also known as image
simplification and reconstruction, creates a low-poly
abstraction using Delaunay triangulation. While
simplification introduces a novel boundary-aware seed
placement approach, our reconstruction step focuses on
restoring intricate details and refining the overall visual
quality. Experiments confirm that the proposed method
achieves a considerable simplification ratio and accurately
represents the crucial features of the underlying image.

The density of the longitudinal component of the spin angular momentum (SAM) vector is calculated for a paraxial vector Gaussian beam with a periodic one-dimensional modulation. For the beam under consideration, the SAM in the initial plane is zero and the polarization is inhomogeneous and linear. When this beam propagates in free space, due to periodic modulation it is effectively divided into two beams with left-handed and right-handed elliptical polarization. That is, in the cross section of the beam, regions with spins of different signs are separated in space, which is a manifestation of the spin Hall effect. This beam can be formed using a metasurface whose transmission periodically depends on one coordinate.

Autorzy analizowanych publikacji opisywali przebieg działań wojennych, zbierali materiały na temat rosyjskich zbrodni wojennych w Ukrainie, analizowali sytuację ukraińskich uchodźców, dokumentowali cierpienia ukraińskich dzieci. Sporo uwagi poświęcono także kwestii stosunków rosyjsko-ukraińskich, ukraińskiej tożsamości narodowej oraz demaskowaniu rosyjskich kłamstw i manipulacji. Na uwagę zasługuje też próba refleksji nad stosunkami polsko-ukraińskimi oraz na pomocy udzielonej Ukrainie zarówno przez państwo polskie, jak i samych Polaków. W ocenie autora przeanalizowane publikacje stanowią doskonały materiał informacyjny, pozwalający Polakom na głębsze poznanie Ukrainy i lepsze rozumienie przyczyn wybuchu wojny rosyjsko-ukraińskiej.
Konstruowanie tożsamości hybrydycznej
Authors: Szpunar Magdalena
Published: November 2024

Procesy hybrydyzacji nie są czymś nowym, choć wcześniej nie były określane za pomocą kategorii hybrydy. Współistnienie, przenikanie się były obserwowane w społecznościach pogranicza, jak i w społecznościach cechujących się wysokim odsetkiem imigrantów. Nasilone ruchy migracyjne, intensyfikacja roli technologii w naszym życiu, ale także globalizacja spowodowała, iż hybrydyzacja, w tym hybrydyzacja tożsamości na stałe wpisała się w kulturowy krajobraz współczesności. Celem artykułu jest operacjonalizacja tożsamości hybrydycznej. Autorka udziela odpowiedzi na pytanie, jakie procesy przyczyniają się do pojawienia się tożsamości hybrydycznej, jakie są społeczne, kulturowe, ale przede wszystkim jednostkowe konsekwencje tego typu tożsamości, jaką wartość niesie ona ze sobą, ale także gdzie należy upatrywać zagrożeń związanych z jej pojawieniem się.
Місця пам’яти, колективна пам’ять та змінні ідентичності в романі-літописі Василя Махна Вічний календар
Authors: Nabytovych Ihor
Published: November 2024

Література може бути особливим locus identitas, поєднуючи індивідуальну та колективну ідентичність, колективну пам’ять і місця пам’яті в літературно-мистецьке ціле. Роман-хроніка Вічний календар українського письменника Василя Махна є особливим художнім відкриттям, художнім дослідженням locus identitas з перспективи майже чотирьох століть кількох етнічних (національних) груп в особливому місці, де зливалися та розділялися межі кількох держав та імперії. На стику трьох різних епох, культур, політики та історії, в особливому хронотопі, герої твору розвивають свою індивідуальність і соціалізацію в багатомовному та культурному просторі. Роман художньо відтворює динаміку взаємовпливів та інтеракцій людських екзистенцій, які народжуються, живуть і виявляються як художнє моделювання як індивідуальної, так і національної міжкультурної ідентичности.

The most significant component of the skeletal and muscular system, whose function is vital to human existence, are the bones. Breaking a bone might occur from a specific hit or from a violent rearward movement. In this study, bone fracture detection was performed using convolutional neural network (CNN) based models, Faster R-CNN and RetinaNet, as well as a transformer-based model, DETR (Detection Transformer). A detailed investigation was conducted using different backbone networks for each model. This study's primary contributions are a methodical assessment of the performance variations between CNN and transformer designs. Models trained on an open-source dataset consisting of 5145 images were tested on 750 test images. According to the results, the RetinaNet/ResNet101 model exhibited superior performance with a 0.901 mAP50 ratio compared to other models. The obtained results show promising outcomes that the trained models could be utilized in computer-aided diagnosis (CAD) systems.

Non-Abelian Gauge Theories and Emerging Space-Time Structures: A New Approach to Quantum Gravity
Authors: Aksakallı Ayhan
Published: November 2024

This paper examines the impact of non-Abelian gauge theories on space-time structures within the context of quantum gravity theory. The study explores the intricate effects of the non-perturbative properties of gauge fields on the topological and geometric structures of space-time, analyzing how these effects align with or differ from the current understanding of quantum gravity theory. The simulations conducted in this study visually model the dynamic effects of gauge fields on the microstructures of space-time, illustrating the role these structures play in quantum gravity theory. The findings suggest the potential for developing new approaches to experimentally test quantum gravity theory. Recommendations for future research include more comprehensive simulations involving different gauge groups and a more detailed investigation of the energetic contributions of these structures. This paper contributes to a broader understanding of quantum gravity theory, offering new insights into its potential applications in the physical world.

Although higher education aims to provide holistic learning and career preparation, there is growing skepticism about its value, with segments of the public scrutinizing concerns about tuition, student loan debt, and job prospects. Between 2015 and 2020, Florida Gulf Coast University implemented a quality enhancement plan (FGCUScholars) that worked to integrate undergraduate research throughout the curriculum to enhance career-ready transferable skills in response to institutional assessments and employer feedback. Results from annual assessments indicated that research participants demonstrated higher skill levels relative to students who completed alternative capstones. Furthermore, continual exposure to research skills throughout the four-year curriculum and emphasis on information literacy led to higher skill levels. This study highlights some positive impacts of undergraduate research on transferable skills, emphasizing their relevance across disciplines.
Enhancing the Writing Competencies of Undergraduate Researchers
Authors: Polk Thomas
Published: November 2024

The ability to effectively communicate, particularly in writing, ranks among the most highly valued competencies employers seek in new hires. Despite this, recent graduates commonly experience challenges when adapting to workplace writing practices. This article explores how undergraduate research experiences prepare students to write beyond the university. The author argues that undergraduate research experiences provide a significant opportunity to enable career-ready writing, but that this opportunity could be enhanced by preparing mentors to more intentionally guide writing development. A qualitative study of 11 undergraduate researchers suggests that students develop a number of genre-specific writing competencies and the genre awareness that is important to preparation for career-ready writing. Based on this analysis, the author offers recommendations for enhancing undergraduate research students’ preparation for career-ready writing.

Published: November 2024

This document constitutes a reflection on the differential approach and interculturality as tools that make it possible to find other pedagogical paths to strengthen accounting education. It is a bet, which leads to approaches from to the territories and theinterweaving of knowledge with rural communities, to understand other economic logics and contribute to some extent to organizational strengthening and local development. Methodologically, it has a descriptive-participatory orientation, since the communities are vital actors in this process. It is evident from this proposal that it is possible to transcend barriers, to promote epistemic threads, between communities and academia, which enable the configuration of identity strengthening dynamics and the exercise of their autonomy, as well as the enrichment of the accounting discipline.
Algunas dicotomías lingüísticas: una conexión entre ciencia del lenguaje y conceptos fundantes
Authors: Corredor  Tapias Joselyn , Romero Farfán César Augusto
Published: November 2024

Este trabajo es continuación de la investigación que, en 2009, produjo el artículo, intitulado: “Quiz de lingüística general: breve relato de una experiencia pedagógica en el aula” (Corredor y Romero, 2009). Tal investigación se concentró en construir, realimentar y actualizar, semestre tras semestre, los contenidos programáticos de la cátedra Lingüística General (en la Licenciatura en Lenguas Extranjeras con énfasis en Inglés y en Francés, hoy Lingüística I: desarrollo histórico en la Licenciatura en Literatura y Lengua Castellana, Escuela de Idiomas, de la UPTC, con varias coincidencias en un buen número de universidades del país).
En esta ocasión, a partir de lo investigado y puesto en práctica en el aula de clase, por más de cinco años, nos dedicaremos a explicar las dicotomías, colegidas de las principales Escuelas Lingüísticas del siglo XX. Quepa recordar que la ciencia del lenguaje nace con un objeto de estudio: la lengua; hacia mediados del siglo retoma el lenguaje, como tal objeto; en las décadas de los setenta y de los ochenta, se centra en el habla (una de las formas de discurso) y, en las postrimerías del mismo, se vuelve hacia la cognición.
