АСИММЕТРИЯ РИТМА СЕРДЦА И СИТУАТИВНАЯ СОНЛИВОСТЬ ОТ ВЕЧЕРА К НОЧИ: ВКЛАД ФАКТОРА ОБЩЕЙ ДНЕВНОЙ СОНЛИВОСТИ
Authors: Демарева В.А. 
Published: January 2025

Настоящее исследование посвящено анализу взаимосвязи между дневной сонливостью, асимметрией сердечного ритма (АСР) и ситуативной сонливостью в вечерне-ночные часы. Актуальность работы обусловлена важностью понимания механизмов автономной регуляции организма и разработки методов мониторинга сонливости, что особенно важно для предотвращения ошибок в критически важных сферах, таких как транспорт и сменная работа. Цель исследования — изучить влияние дневной сонливости на динамику АСР в вечерне-ночной период, а также выявить корреляции между ситуативной сонливостью и АСР. В эксперименте приняли участие 50 здоровых добровольцев, разделенных на группы по уровню дневной сонливости. Использовались субъективные шкалы для оценки сонливости и точные методы анализа АСР. Результаты показали, что у участников с более высокой дневной сонливостью наблюдается снижение показателей АСР с наступлением биологической ночи, что вероятно связано с увеличением физической и когнитивной усталости. В группе с высокой дневной сонливостью также были выявлены значимые отрицательные корреляции между ситуативной сонливостью и изменчивостью сердечного ритма. Эти данные могут быть использованы для создания систем мониторинга усталости и сонливости в различных областях, таких как транспорт, сменная работа и спорт.
This study focuses on analyzing the relationship between daytime sleepiness, heart rate asymmetry (HRA), and situational sleepiness during the evening-night hours. The relevance of the work is determined by the importance of understanding the mechanisms of autonomic regulation in the body and developing methods for sleepiness monitoring, which is especially crucial for preventing errors in critical areas such as transportation and shift work. The aim of the study was to investigate the effect of daytime sleepiness on the dynamics of HRA during the evening-night period and to identify correlations between situational sleepiness and HRA. The experiment involved 50 healthy volunteers, divided into groups based on their level of daytime sleepiness. Subjective sleepiness scales were used for assessment, along with precise methods for analyzing HRA. The results showed that participants with higher daytime sleepiness exhibited a decrease in HRA indicators with the onset of biological night, which is likely associated with increased physical and cognitive fatigue. In the high daytime sleepiness group, significant negative correlations were also found between situational sleepiness and heart rate variability. These findings could be used to develop systems for monitoring fatigue and sleepiness in various fields such as transportation, shift work, and sports.

W rezultacie badań – powstała koncepcja „zielonej” rewitalizacji, która powinna stanowić pewien model przeprowadzenia takich przedsięwzięć w polskich miastach w XXI wieku.
Świadomość dzieci o osobach z niepełnosprawnościami i ich barierach
Authors: Szadura Kornelia , Gleń Piotr 
Published: January 2025

W Polsce idea projektowania uniwersalnego, choć zyskała popularność w latach 90. XX wieku, była już wcześniej związana z prawami człowieka i urbanistyką. Obecnie stanowi standard i wymóg prawny w wielu aspektach projektowych. Tematyka ta dotyka również szeroko pojętego zagadnienia Zrównoważonego Rozwoju (SDG 11), które promują tworzenie miast bez barier i inkluzywnych przestrzeni dla osób z niepełnosprawnościami. Projektowanie uniwersalne, oparte na różnorodności i potrzebach wszystkich użytkowników, ma na celu eliminację przeszkód technicznych, społecznych i psychologicznych, które ograniczają samodzielność i uczestnictwo w życiu społecznym. Istotnym wyzwaniem pozostaje podnoszenie świadomości społecznej oraz uczenie empatii, co prowadzi do naturalnego projektowania przestrzeni dostępnych dla każdego. Pomocne mogą stać się warsztaty dla dzieci, które wprowadzą świadomość o osobach niepełnosprawnych i ich barierach, jak i również pokażą dotychczasową świadomość na podany temat. Wyniki ukazują, że dzieci miały styczność z osobami niepełnosprawnymi poruszającymi się na wózku i potrafią wskazać bariery architektoniczne dla tych osób, lecz mniejsza jest świadomość o niepełnosprawności wzrokowej.
Design and optimization toward ultra-high sensitivity in impedance flow cytometry devices
Authors: Abhinav Vishnuram , Naik Tejas R. 
Published: January 2025

Abstract
This work presents a comprehensive study on the sensitivity optimization of electrical impedance flow cytometry devices for identifying analytes suspended in a flowing liquid. The optimization is achieved by investigating the influence of various parameters, including applied frequency, electrode geometry dimensions, bacterial properties, and buffer characteristics. The study utilizes COMSOL Multiphysics simulation to analyze the impedance variation based on differential Maxwell’s equations solved using finite element methods. The frequency optimization reveals that the sensitivity peak is around 12.6 kHz when considering imaginary impedance due to medium conductivity. Geometry optimization involves electrode dimensions with a length of 30 µm and a gap of 15 μm, as well as a channel width and height of 20 μm. Furthermore, the paper explores the effect of buffer conductivity, showing that it plays a significant role in defining total impedance with or without cells/particles. Higher buffer conductivity leads to dominant changes in real impedance, while lower conductivity affects imaginary impedance more prominently. The study also investigates the impact of variations in bacterial parameters, such as cell membrane permittivity and cytoplasm conductivity. These parameters influence total impedance, with cell radius showing a notable effect on sensitivity. By optimizing these parameters, the sensitivity and performance of impedance-based flow cytometry devices can be enhanced, making them more effective for bacterial analysis and characterization in various applications.

Published: January 2025

Abstract
We established atomic layer deposition (ALD) process of InZnOx (IZO) and fabricate the ALD IZO FETs for comprehensive characterization, aimed at advancing nanosheet structure and monolithic 3D (M3D) integration technologies. Thermal stability and composition/thickness dependence on device characteristics are systematically explored. Our findings reveal that ALD IZO FETs maintain high thermal stability at temperatures up to 400 °C, and we identify critical trade-offs among key parameters such as mobility, threshold voltage (Vth), and initial Vth shift (ΔVth) under positive bias stress conditions. ALD IZO FETs show higher mobility, lower Vth, and especially smaller initial ΔVth than previously reported our ALD InGaOx (IGO) FETs. These improvements are linked to the intrinsic differences in oxygen dissociation energy between the Zn and Ga in the compound of InOx. The material properties and device behavior of IZO FETs obtained in this work will provide insights for their application in M3D integration.

Introdução: A insuficiência cardíaca (IC) é uma síndrome clínica, na qual o coração é incapaz de bombear sangue de forma atender às necessidades metabólicas tissulares, ou pode fazê-lo somente com elevadas pressões de enchimento. A IC é uma complicação grave, geralmente progressiva e irreversível, que pode comprometer a maioria dos pacientes cardíacos. Objetivo: O artigo objetiva trazer uma análise epidemiológica, da distribuição e impactos da Insuficiência Cardíaca no Brasil e nas suas macrorregiões, no período de janeiro de 2014 a junho de 2024. Metodologia: Trata-se de um estudo epidemiológico, retrospectivo com abordagem quantitativa e temporal, com dados referentes à prevalência e impactos das internações no período de 2014 a 2024, nas cinco regiões brasileiras. Resultados: Foram registradas 2.105.962 internações por Insuficiência Cardíaca (IC) no Brasil. A Região Sudeste apresentou o maior número de casos, com 885.365 internações (42%), seguida pelas regiões Nordeste (22,8%) e Sul (22,4%). Tais regiões, ainda se destacaram pelo maior número de óbitos, onde a região sudeste apresentou 46% de óbitos, seguida pelo Nordeste (22%) e Sul (19%), totalizando 239.704 mortes no período. A média de permanência hospitalar variou entre as regiões, sendo mais elevada no Nordeste (8,3 dias) e mais baixa no Centro-Oeste (6,3 dias), o que ressalta a possibilidade de desigualdades no acesso e qualidade dos serviços de saúde. A análise por faixa etária revelou que 87,9% das internações ocorreram em indivíduos com 50 anos ou mais, com destaque para aqueles com 80 anos ou mais. Quanto à distribuição por raça/cor, a população branca apresentou o maior número de internações e em relação ao sexo houve predominância do sexo masculino. Conclusão: A mortalidade causada pela IC está constantemente associada aos indicadores individuais, sociais, econômicos e de serviços de saúde. Portanto, a síndrome de IC tem diferentes aspectos epidemiológicos e regionais, principalmente, na diversidade da etiopatogenia. Nesse sentido, há necessidade de melhoria na qualidade assistencial e maiores ações por parte do governo para conscientizar a população sobre como prevenir a IC e como tratar corretamente o aparecimento desta enfermidade.

Authors: CAMAPUM LARISSA ALESSANDRA DA COSTA , Viana Deuzuita dos Santos Freitas 
Published: January 2025

A nanobiotecnologia combina a ciência dos materiais com as biológicas, criando produtos inovadores. Este estudo experimental avaliou o efeito de nanopartículas de prata (AgNP) no processo cicatricial de 25 camundongos Mus musculus, divididos em 5 grupos (2 controles e 3 experimentais). Os animais foram mantidos em condições controladas e submetidos a feridas mecânicas na pele dorsal, tratadas com AgNP a 10% por aplicação tópica ou gavagem. O experimento durou 21 dias, após os quais os animais foram sacrificados para análise histológica. Observou-se que fibroblastos, colágeno e neovascularização foram marcantes nos grupos tratados, enquanto células da fase inflamatória, como neutrófilos, tiveram baixa presença. A fase proliferativa e o remodelamento mostraram destaque celular nos grupos experimentais. Macroscopicamente, o grupo 5 (tratado com AgNP a 10% por gavagem e aplicação tópica) apresentou maior regressão da ferida. Não foram identificadas células atípicas nos tecidos analisados. Assim, os resultados confirmam que o processo cicatricial seguiu padrões descritos na literatura, com evidências de que a combinação de tratamentos potencializa a reparação tecidual.
Representasi Folksong dan Memori Kinetik dalam Nyanyian Jemaat Gereja Protestan Maluku
Authors: Mahoklory Novian Hendrik , Lattu Izak Y.M , Lauterboom Mariska 
Published: January 2025

This article aims to examine the Maluku Protestant Church (GPM) Congregation Songbook using the kinetic memory study to find the representation of folksong in implementing worship in Maluku. The author uses descriptive qualitative methods with data collection techniques and interviews with key informants, including the GPM synod chairman and two songwriters from this congregational songbook, to obtain the desired results. Based on the results of the research, the author found that it is true that the GPM congregational songbook is the work of the Maluku people used in the worship life of the Maluku people, which is inseparable from the context of the social and cultural life of the Maluku people so that this congregational song can be referred to as the folksong of the Maluku people which is contextualized by theological and cultural understanding. The next finding also presents several song titles and lyrics that contain kinetic memory so that when sung with body movements, it will liven up the atmosphere of worship that is more vibrant and excite the congregation.
Secondary Fluorescence in Electron-Microprobe Analysis Near Grain Boundaries, with Emphasis on Sphalerite and Au-Ag-Hg Alloy
Authors: Healy Raymond E. 
Published: January 2025

Abstract
Simplified modeling of electron interactions, X-ray absorption, and secondary fluorescence effects together with a series of test analyses and modeling using CalcZAF/FANAL confirm that electron-microprobe compositions of sphalerite and Au-Ag-Hg alloy are susceptible to analytical contamination from adjacent sulfide grains lying within extensive volumes of secondary fluorescence (i.e., radii of ∼50 and ∼20 μm, respectively). Compositions of sphalerite encapsulated in pyrite for geobarometric analysis, and from a series of points approaching a boundary with pyrite (i.e., concentration-gradients of Fe) for equilibration studies, may give spuriously high Fe contents due to secondary fluorescence of Fe in the adjacent pyrite, and thereby lead to erroneous interpretations. Similarly, anomalously high observed Cu contents of free sphalerite occurring in the Trout Lake Cu-concentrate can be attributed to secondary fluorescence of Cu in chalcopyrite disease in the sphalerite grains or of Cu in adjacent chalcopyrite, and not the preferential recovery of sphalerite with Cu-rich compositions during chalcopyrite or Cu flotation.
Potentially false-element concentrations due to secondary fluorescence near grain boundaries is an inherent pitfall in the analysis of very small mineral grains, near grain boundaries, and in all diffusion studies. The factors determining the potential magnitude of secondary fluorescence for the specific mineral pair under investigation should be routinely considered, and probably modeled, when operating near grain boundaries (i.e., within ∼100 μm), either by the simplified method used here or by a computer modeling program such as CalcZAF/FANAL.
Proof of Uranyl Deposition in Unconformity-Related Uranium Deposits, Athabasca Basin, Canada: Evidence from Synchrotron XAS and XPS Analyses of Hematite

Published: January 2025

Abstract
Except for the recently discovered stable U4+ chloride complex under reduced conditions at high temperatures, genetic models for the formation of uranium deposits had almost invariably invoked the pivotal roles of soluble U6+ species for the transport of uranium in fluids and their reduction to sparingly soluble U4+ as the deposition mechanism. However, the questions of when and how this reduction occurred in most uranium deposits, such as those in the Athabasca basin, Saskatchewan, Canada, are often not clear. The unconformity-related uranium deposits in the Athabasca basin are commonly accompanied by extensive and intensive alteration halos, including hematite-rich alteration or hematitization. Previous U L3-edge X-ray absorption near-edge structure (XANES) studies of uranium-bearing fluid inclusions and thermodynamic modeling demonstrated uranium transport as uranyl (UO22+) species in hypersaline fluids in the Athabasca basin. Electron microprobe analyses reveal that hematite inclusions in quartz overgrowths, as well as some disseminated hematite in clay mineral (illite-chlorite) matrices, in both orebodies and associated alteration halos from five uranium deposits (Arrow, Cigar Lake, Key Lake, McArthur River, and Phoenix) in the Athabasca basin contain elevated contents of uranium (up to 2.16 wt.% UO3). Synchrotron U L3-edge X-ray absorption spectroscopy (XAS) and U 4f X-ray photoelectron spectroscopy (XPS) analyses show that uranium in hematite occurs dominantly as the uranyl species, providing unambiguous evidence for direct uranyl deposition in the Athabasca basin. However, direct uranyl deposition with hematite during a single episode of hydrothermal alteration can account for only low-grade uranium mineralization. High-grade uranium deposits in the Athabasca basin required multiple episodes of hydrothermal alteration and/or other deposition mechanisms, such as those related to reduction.
