Authors:   Kazan State Energy University, Cherkasov Grigory F. , Khizbullina Radmila R. ,   Kazan State Energy University
Published: March 2024

The article updates the need to study the role and importance of sports in the system of socialization and health-saving behavior of youth in the region (using the example of the Republic of Tatarstan). The understanding of the socialization system is being updated through the prism of the totality of the diversity of determination mechanisms and conditions that can act, including the conditions for the formation of value systems for a healthy lifestyle and playing sports, which formulated the research problem presented in this article. The results of the author's sociological research obtained by the questionnaire in the Republic of Tatarstan in 2023 are presented (N = 820 people aged 18 to 35 years, a target sample; the selection criteria – a gender, an age, a region of residence). During the analysis of the survey data, the assumption was formulated that at the regional level, the role of sports and sports infrastructure in the system of socialization of youth and the implementation of health-saving behavior can be assessed through empirical indicators – internal and external determinants. Today It that young people in general highly appreciate the role of sports and the prestige of a healthy lifestyle, as well as the orientation of the infrastructure of their region towards sports as a priority form of leisure and recreation among young people, designating sports infrastructure as one of the significant conditions in the formation of value systems for health-saving behavior and motivator for playing sports and developing the sports movement among the younger generation. The analysis of the data obtained and identification of the role of sports as one of the determinative imperatives in the system of socialization of youth objectifies its role in the focus of the need to understand the direct influence of internal attitudes on playing sports and environmental factors, such as sports infrastructure, conditions, mechanisms, directions and programs for supporting sports among youth of the region in modern conditions.
Policy regarding fertility and healthy lifestyles in Russia: Features of incentives for citizens
Authors:   National Medical Research Center for Therapy and Preventive Medicine, Suvorov Valeriy V.
Published: March 2024

Social and demographic problems associated with an increase in the birth rate and the number of citizens leading a healthy lifestyle have many intersection points both in the field of health and in the field of socio-economic relations. Projects to improve fertility indicators and healthy lifestyles, presented in strategic documents and relevant policies, reflect different attitudes of the authorities towards stimulating citizens. Unlike having children, maintaining a healthy lifestyle by citizens does not provide for material or non-material incentives from the state. At the same time, the currently existing material incentives for the birth rate show their insufficiency, which raises the question of additional or alternative ways to motivate citizens. The solution to this approach requires an integrated approach. On the one hand, the use of an information resource available through the education system and the media space opens up the opportunity for the authorities to influence the attitude of citizens towards issues of fertility, values and status of the family and health. In this context, the attitude of citizens towards the promotion of a healthy lifestyle, as one of the conditions for strengthening the family and maintaining reproductive health, would also change. On the other hand, the media must popularize the idea that individual unlimited consumption also has a limit in the form of health and life expectancy. Consumption can be expanded at the expense of families if the state stimulates family consumption, and not just distributes one-time cash incentives.

The article talks about diplomatic, economic and military measures on the part of the Russian Empire aimed at annexing new eastern lands, including Manchuria. The efforts of our country related to solving this problem are analyzed in historical retrospect. Special attention is paid to the construction of the Manchurian Railway (later the Chinese Eastern Railway), which passed through the specified province of China. The reasons that did not allow the annexation of Manchuria to the territory of our country at the time are analyzed. The significance of these events is assessed in the light of the current geopolitical situation in the world.

The Appearance and Development of Metal Container in Silla Ancient Tombs
Authors:   Central Institute of Cultural Heritage, Bang Min-Hee
Published: March 2024

The purpose of this study is to focus on the burial of metal containers, which is a features of ancient tombs from the Silla Dynasty of the Three Kingdoms, to gather metal containers buried in ancient tombs and graves in and outside of Gyeongju to trace the meaning of burying metal containers with the dead in the Silla society. Metal containers buried in the ancient tombs of Silla range in materials from gold to silver, gilt bronze, bronze, and steel, and also have diverse types such as personal plates for food call gobae, wan, sohap, etc., cooking containers such as sotga and siru, storage containers such as janggyeongho, and even containers used for rituals like jeong, chodu, and choho. Burial of such metal containers are materialistic expressions of burial customs and belief of the afterlife are concentrated in Gyeongju, which was the center of Silla, while being buried in ancient tombs in some other areas outside of Gyeongju. Therefore, this study conducted analysis focusing on two aspects. metal containers buried in ancient tombs were reviewed to examine the types of metal containers, while on the other hand. Results of this showed that in addition to the temporal development mode of ancient tombs in which metal containers were buried, this practice spread to areas outside of Gyeongju as time passed. Based on this, the meaning of burying metal containers in tombs of the Silla society was evaluated. Meanwhile, the burial of metal containers also had social meaning. In the center of Silla, multiple metal containers with various materials and types were buried in the greatest tombs, and this custom of burying metal containers spread to the tombs of people of lower status. It is evident that in the fifth century and latter Silla Dynasty, the burial of metal containers was widely practiced among the upper echelons in central Silla. Burial of metal containers outside of Gyeongju were found after the late 5th century, and among the various regions that shared the ancient tomb culture of Silla, metal containers were found only in the ancient tombs of Gyeongsan, Daegu, Changnyeong, and Yangsan, and therefore, it was judged that this could be interpreted as the relationship between the central and local governments. Just like other artifacts that show hierarchy, the burial of metal containers can also hint to the relationship of the central and local regions, and it can be presumed that areas with ancient tombs that buried metal containers had higher status compared to other regions.
Reutilización de productos textiles vs. infracción de un derecho de marca. Estrategias materiales y de litigación transfronteriza
Authors: Antón Juárez Isabel
Published: March 2024

La industria de la moda, tanto el negocio basado en el fast fashion como el de los productos de lujo, se ha configurado en gran medida en torno a una producción masiva. Pero no sólo eso, la producción textil en sí misma genera una importante cantidad de residuos (ad ex., telas sobrantes, trozos de piel, etc.) que se desechan directamente. De hecho, a pesar de que las normas europeas sobre el tratamiento de residuos en Europa están cambiando (prueba de ello es la Ley 7/2022 de 8 abril, de residuos y suelos contaminados, fruto de la Directiva europea 2018/851) todavía las empresas generan un importante número de residuos a la hora de producir y también cuentan con mucho stock sobrante al final de cada temporada. De este modo, algunas de las soluciones que algunos expertos ofrecen para que la industria sea cada vez más sostenible y circular es que las empresas textiles fabriquen menos y se reutilice más lo ya fabricado. El upcycling es una técnica que consiste en reutilizar productos ya usados para que puedan tener una segunda vida. Esta reutilización, en muchas ocasiones basada en técnicas creativas, no plantea mayores problemas legales cuando es la propia marca de moda la que reutiliza sus productos o llega a un acuerdo con otra empresa para colaborar juntas y así aprovechar el stock sobrante. El problema surge cuando, es un tercero el que utiliza partes de productos protegidos por un derecho de marca y sin consentimiento del titular, los añade a otros productos. Esta cuestión jurídica que nos planteamos todavía resulta ser más interesante cuando percibimos que en la mayoría de las ocasiones en esas nuevas creaciones de upcycling se suelen reutilizar partes de productos donde aparecen firmas de moda muy conocidas mundialmente y que pertenecen al segmento de productos considerados “de lujo”. El objetivo de este trabajo es triple, así vamos a analizar: 1) Si la técnica del upcycling podría ser contraria a un derecho de marca de la UE; 2) Si el upcycling encajaría dentro del concepto de agotamiento europeo del derecho de marca y en qué medida podría convenir adaptar el agotamiento para conseguir una industria más sostenible; 3) Los aspectos desde una perspectiva internacional privatista se deberían tener presente en el caso de que el titular de la marca se decidiera a demandar por infracción marcaria ante tribunales europeos.

La salida del Reino Unido de la Unión Europea ha acarreado numerosas consecuencias para la gente de mar, sin que éstas hayan sido abordadas por el instrumento que canaliza las relaciones entre las partes, esto es, por el Acuerdo de Comercio y Cooperación. El objetivo del presente trabajo consiste en analizar las consecuencias más significativas para este colectivo de personas trabajadoras desde el punto de vista laboral, centrándose específicamente en dos aspectos: la finalización de la libre circulación de trabajadores entre el Reino Unido y la UE y la reaparición del temor por una competencia social desleal como consecuencia de una posible rebaja de las condiciones sociales de la gente de mar.
Reconocimiento en la Unión Europea de la filiación de hijos de parejas del mismo sexo
Authors: Lorente Martínez Isabel
Published: March 2024

El Derecho de la Unión Europea busca promover no solo la libre circulación de personas, servicios y capitales, sino también la libre circulación de productos jurídicos y situaciones jurídicas, como la filiación, el nombre, las personas jurídicas, las sucesiones, entre otros. Sin embargo, es importante reconocer que las personas LGBTI pueden enfrentar dificultades al cruzar las fronteras dentro de la UE debido a la falta de reconocimiento o protección de sus relaciones y los efectos legales de las mismas en algunos países miembros. Aunque la libre circulación de personas es un principio fundamental de la UE, la plena igualdad y el reconocimiento de los derechos de las personas LGBTI en todos los Estados miembros aún puede ser un desafío. Y en este trabajo se pondrá el foco de atención sobre el reconocimiento de la filiación y los hijos de parejas del mismo sexo.

At one time, we thought that artificial intelligence was just fantasy. However, we did not imagine that this dream would become a reality in the 21st century and would have such an impact on our day-to-day lives. Nowadays, AI has made many difficult tasks in our daily lives easier, and work time has also decreased. Currently, Artificial Intelligence is being used in various sectors. But, after witnessing the capability, it is clear that AI will revolutionize the business world. Advertising is a significant part of the business sector. AI is expected to emerge as a game changer, especially in advertising. New entrepreneurs can market and advertise their products at relatively low cost. With AI, they can hire prominent endorser’s "personality" to advertise at a reasonable cost, which is currently out of imagination for new entrepreneurs. AI is going to emerge as a generational advancement for the business and advertising world around the globe. If advertisers develop an AI that can learn the personality of an individual and can ethically use the character to create ads or a live video, the expense of marketing will significantly decline. Statistical tools will be used to analyze the quantitative data, and thematic examination will be applied to dissect the qualitative data. Try to fill the gap and overcome the problem using primary and secondary data. Find the best ways to reduce the risk factors and expand economic growth.

Published: March 2024

Aim: The aim of this study was to verify the color variation between different composite resins and the Vita Classical Shade Guide. Methods: Two-millimeter thickness samples were made (n = 6) from eight commercial brands of composite resin (shade A2): Charisma (Kulzer), Forma (Ultradent), Harmonize (Kerr), Luna (SDI), Opallis (FGM), Oppus Bulk Fill (FGM), Vittra (FGM) and Filtek Z250 XT (3M ESPE). Specimens were stored in distilled water for 7 days and then polished. Color measurements of samples and A2 shade of the Vita Classical Shade Guide were performed using the Vita Easy Shade Advance 4.0 spectrophotometer on a black background. Color variations were calculated using the CIEDE2000 formula, considering values ≥0.81 being noticeable by the human eye and ≥1.77 being clinically unacceptable. Results were statistically analyzed with a 5% significance level. Results: Color variation (ΔE) of composite (E1 ) compared to the Vita Classical Shade Guide (E0 ) was greater than clinically acceptable for all the materials evaluated in this study. Forma (ΔE=2.08 ± sd=0.47) and Filtek Z250 XT (2.50 ± 0.20) had the smallest amount of color variation values found in the results. Harmonize (3.32 ± 0.63) presented values similar to Filtek Z250 XT, but it was worse than Forma. Vittra (3.51 ± 0.28), Charisma (3.80 ± 0.20), Opallis (4.24 ± 0.30) and Luna (5.67 ± 0.20) did not differ among each other and presented higher color variation than Forma, Filtek Z350XT and Harmonize. Oppus Bulk Fill (13.94 ± 1.12) was the composite with the greatest color variation. Conclusions: The findings in this study show that attention should be taken when using the Vita Color Shade Guide for composite shade selection.

Published: March 2024

In the modern power grid, characterized by the increased penetration of power electronics and extensive utilization of renewable energy, inverters-based power plants play a pivotal role as the principal interface of renewable energy sources (RESs) and the grid. Considering the stability characteristics of grid-following (GFL) inverters when the grid is relatively weak, the application of grid-forming (GFM) controls becomes imperative to enhance the stability of the entire power plant. Thus, there is an urgent need for suitable and effective models to study the interaction and stability of the paralleled inverters employing GFL and GFM controls. Thus, the small-signal modeling with full-order state space model and eigenvalues analysis is presented in this paper. First, the small-signal state-space model of the individual GFL and GFM inverters is obtained considering the control loop, interaction, reference frame, transmissions, and time delays. Then, the models of the individual inverter are extended to the hybrid inverters to study the effects of the GFM inverters on the small- signal stability of the entire system. And, the impacts of the inertia and damping are analyzed by the eigenvalues of the state-transition matrix. Case comprising three parallel GFL inverters and two GFL inverters with one GFM inverter, respectively, are studied to examine the effectiveness and accuracy of the model. Finally, the stability margin obtained from the eigenvalue analysis of the entire system is verified by time-domain simulations.
Ecotoxicity of 2,4-dichlorophenol to Microsorium pteropus by High Spatial Resolution Mapping of Stoma Oxygen Emission
Authors: Zhong Ning , Zhang Daoyong
Published: March 2024

Abstract: Toxicity of emerging organic pollutants to photosystems of aquatic plants are still not well clarified. This study aimed to develop a novel ecotoxicological experimental protocol based on nanoscale electrochemical mapping of photosynthetic oxygen evolution of aquatic plants by SECM (scanning electrochemical microscopy). The protocol was also checked by confocal laser scanning microscopy (CLSM), the traditional Clark oxygen electrode method and chlorophyll fluorescence technique. The typical persistent organic pollutant 2,4-dichlorophenol (2,4-DCP) in water environment and the common aquatic Microsorium pteropus (M. pteropus) were chosen as the model organic pollutant and tested plant, respectively. It was found that the SECM method could well discriminated the responses of stoma micromorphology and spatial pattens of photosynthetic oxygen evolution on single stoma. The shape of stoma blurred with increasing 2,4-DCP concentration, which was in good agreement with the CLSM images. The dose-response curves and IC50 values obtained from the SECM data were verified by the data measured by the traditional Clark oxygen electrode method and chlorophyll fluorescence test. The IC50 value of single stoma oxygen emission of 24 h exposed plant leave, which was derived from the SECM current data (32535 μg L-1), was close to those calculated from the maximum photosynthetic efficiency (Fv/Fm) measured by chlorophyll fluorescence test (33963 μg L-1), and the Clark oxygen electrode method photosynthetic oxygen evolution rate (32375 μg L-1). The 72 h and 96 h 2,4-DCP exposure data further confirmed the reliability of the nanoscale stoma oxygen emission mapping methodology for ecotoxicological assessment. In this protocol, the procedures for how to collect effective electrochemical data and how to extract useful information from the single stoma oxygen emission pattern were well established. This study showed that SECM is a feasible and reliable ecotoxicological tool for evaluation of toxicity of organic pollutants to higher plants with unique nanoscale visualization advantage over the conventional methods.

Published: March 2024

This study addresses the critical issue of dowel-bearing strength in Bambusa blumeana, a key sus-tainable construction material crucial for climate change mitigation. Given the lack of bamboo connection standards, the research focuses on determining the dowel-bearing strength of Bambusa blumeana, emphasizing factors such as dowel diameter, node placements, and the physical prop-erties of bamboo. A predictive equation is derived, enhancing the practicality of bamboo in struc-tural design. The results underscore a notable correlation between dowel diameter and character-istic strength, with implications for engineering practices. Node placements significantly affect dowel-bearing capacity, while bamboo's physical attributes, including thickness, culm diameter, and moisture content, exhibit modest correlations with strength. The derived equation aims to assist in structural design, mitigating splitting and bearing failures in bamboo structures. This research establishes a foundation for optimizing the use of Bambusa blumeana in sustainable construction, advancing the understanding of its dowel-bearing strength for improved sustainability and resili-ence in the construction industry. Future research suggestions include exploring bamboo-mortar composites, additional node placements, and employing more comprehensive empirical equations and curve-fitting techniques. The study advocates for further investigations with more diverse and larger bamboo samples to bolster robustness. Additionally, delving into bamboo ductility may offer valuable insights.
A Systematic Review on Heat Transfer and Pressure Drop Correlations for Natural Refrigerants
Authors: Carella Alberta , D’Orazio Annunziata
Published: March 2024

Due to environmental concerns, natural refrigerants and their use in refrigeration and air conditioning systems are receiving more attention from manufacturers, end users and the scientific community. The study of heat transfer and pressure drop is essential for accurate design and more energy efficient cycles using natural refrigerants. The aim of this work is to provide an overview of the latest outcomes related to heat transfer and pressure drop correlations for ammonia, propane, isobutane and propylene and to investigate the current state of the art in terms of operating conditions. Available data on the existing correlations of heat transfer coefficient and pressure drop for natural refrigerants have been collected through a systematic search. Whenever possible, validity intervals are given for each correlation and the error is quantified. It is the intention of the authors that this could be a valuable support for researchers and an aid to design, with particular reference to heat pumps. A procedure based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was adopted, and the Scopus database was used to query the relevant literature. A total of 135 publications qualified for inclusion in the survey; 34 articles report experimental investigations for not usual geometric conditions. Of the 101 selected papers related to usual geometric conditions, N = 50 deal only with HTC, N = 16 deal only with pressure drop and the remainder (N = 35) analyse both HTC and pressure drop. Among the 85 HTC papers (N = 53) deal with the evaporating condition, N = 30 with condensation and only N = 2 with the heat transfer correlations under both conditions. Most of the 101 articles concern propane and isobutane. The high temperatures are less widely investigated.
Hawking Radiation as a Manifestation of Spontaneous Symmetry Breaking
Authors: Arraut Ivan
Published: March 2024

We demonstrate that the black hole evaporation can be modelled as a process where one symmetry of the system is spontaneously broken continuously. We then identify three free-parameters of the system. The sign of one of the free-parameters, governs whether the particles emitted by the black-hole are fermions or bosons. The present model explains why the Black Hole evaporation process is so universal. Interestingly, this universality emerges naturally inside certain modifications of gravity.

Published: March 2024

Genetic parameters of overreach, term and acuteness in Peruvian Paso horses (PPH) have not been determined to date. It is important to estimate these parameters for application in PPH breeding, therefore, the aim of this study was to estimate the heritability, repeatability, and genetic correlations under field conditions of overreach, term, and acuteness of PPHs. The study included records of up to 137 stallions and mares. All measurements were recorded in MP4 video format with a resolution of 1920 x 1080 megapixels and at 60 frames per second. All traits were measured three times (once per stride), and each trait was analyzed. KINOVEA software version 0.9.5 was used to analyze the measurements. A multivariate repeated measures animal model with sex effect was used to estimate the variance components for each trait using WOMBAT software. The results showed heritability of 0.411, 0.476 and 0.405, for the traits of overreach, term, and acuteness, respectively. Repeatability was high in all traits (> 0.78). Genetic additive correlations ranged from -0.30 to 0.49. It can be concluded that overreach and term have high heritability values, which allows these traits to respond better in a selection process, unlike acuteness which has a moderate heritability value.
Accurate Diagnosis of SARS-CoV-2 JN.1 by Sanger Sequencing of Receptor-Binding Domain Is Needed for Clinical Evaluation of Its Immune Evasion
Authors: Lee Sin Hang
Published: March 2024

Background: SARS-CoV-2 Omicron JN.1 has the highest number of amino acid mutations in its receptor binding domain (RBD) and has acquired a hallmark L455S mutation. The immune evasion capability of JN.1 is a subject of scientific investigation. The US CDC used RT-qPCR SGTF as the proxy indicator of JN.1 infections for evaluation of the effectiveness of updated monovalent XBB.1.5 COVID-19 vaccines against JN.1 and recommended that all persons aged ≥6 months should receive an updated COVID-19 vaccine dose.
Objective: Recommend Sanger sequencing for diagnosis of JN.1 infections to generate the data based on which guidelines are made to direct vaccination policies.
Methods: The RNA in nasopharyngeal swab specimens from patients with clinical respiratory infection was subjected to nested RT-PCR, targeting a 398-base segment of the N-gene and a 445-base segment of the RBD of SARS-CoV-2 for amplification. The DNA sequences were analyzed for amino acid mutations.
Results: The N-gene sequence showed Q229K, usually associated with Omicron BA.2.86 (+JN.1). The RBD sequence showed 24 amino acid mutations, including the hallmark L455S mutation for JN.1 and the V483del for BA.2.86 lineage.
Conclusions: The CDC should consider Sanger sequencing of the RBD to diagnose JN.1 infections for statistical analysis in making vaccination policies.
Coastal Vulnerability Assessment in the southern Valparaíso Region, Chile
Authors: Saavedra Véliz Felipe , Negro Valdecantos Vicente
Published: March 2024

The coastal zone of the Valparaíso Region has been historically threatened by its natural and anthropogenic conditions, which demands efficient management for the adaptation and mitigation of the impacts that occur on the coast, especially in the face of the growing effects of climate change. As a contribution to decision makers in the development of strategic actions through adaptation plans, this study presents an approach to coastal vulnerability in the southern part of the region, applying the Coastal Vulnerability Index considering the variables geomorphology, coastal slope, changes in sea level, coastal erosion, tidal range, and wave height. The result illustrates a sectorization of the coast according to the degree of vulnerability, where the sectors formed by fine sandy beaches near river mouths and estuaries present greater risks to climatic events than those rocky stretches with medium-low cliffs.

Published: March 2024

Darier disease (DD) is an autosomal dominant disorder due to mutation of ATP2A2 gene causing an isolated skin manifestation based on keratinocyte disconnection and apoptosis. Systemic manifestations of DD have not been demonstrated so far although a high incidence of neuropsychiatric syndromes suggest an involvement of central nervous system. A Novel ATP2A2 Gene Mutation c.118G>A, causing keratinocyte and cardiomyocyte disconnection in Darier disease, is reported. Their common pathologic pathway, still unreported, was documented by both skin and left ventricular endomyocardial biopsy because of cardiac dilatation and dysfunction appeared several decades after skin manifestations.Keratinocyte disconnection was paralleled by cardiomyocyte separation at lateral junction. Cardiomyocyte separation was associated to cell disarray, sarcoplasmic reticulum dilatation and increased myocyte apoptosis. Clinically, hyperkeratotic skin papules were associated to chest pain, severe muscle exhaustion and ventricular arrhythmias that improved following administration of aminophylline, a phosphodiesterase inhibitor enhancing SERCA2 protein phosphorylation.Specific mutations of ATP2A2 gene may cause cardiac involvement in patients with DD. Cardiac pathologic changes are similar to those documented in the skin including cardiomyocyte disconnection that promotes precordial pain and cardiac arrhythmias. Phosphodiesterase inhibitors, enhancing SERCA2 protein phosphorylation may substantially attenuate the symptoms.
Fishery Products Safety, Processing and Utilization
Authors: Samarajeewa Upali
Published: March 2024

Abstract
Global marine fish harvest has reached a plateau over the last decade. Efforts to increase aquaculture tend to face limitations in water resources and contamination problems. Of the current fish harvest at least 50% is discarded as waste. The chemical and microbiological contaminations limit the utilization of harvested fish. There is a need to improve fish preservation to minimize spoilage and process them into more appealing products. Instead of resorting to individual food processing methods, the efficiency of processing could best be increased by a combination of conventional and modern processing methods, or combinations of modern processing methods. Fish waste is a rich source of oils containing essential fatty acids, polypeptides, and amino polysaccharides that could be utilized through upscaling of the current scientifically proven methods, to new processing technologies.

In our study we investigated the accelerated aging process of PLA under 253.7 nm UV-C irradiation with the use of GPC, NMR, FTIR, DSC methods and formal kinetic analysis. The results of GPC and DSC indicated a significant degree of destructive changes in PLA macromol-ecules, while spectroscopic methods NMR and FTIR showed maintenance of PLA main structural elements even after a long time of UV exposure. In addition to that, the GPC method displayed the formation of a high-molecular fraction starting from 24 hours of irradiation, and an increase in its content after 144 hours of experiment. It has been showed for the first time that a distinctive feature of prolonged UV exposure is the occurrence of intra- and intermolecular radical recom-bination reactions, leading to the formation of a high-molecular fraction of PLA decomposition products. This causes the observed slowdown of the photolysis process. It was concluded that photolysis of PLA is a complex of physicochemical processes, the mechanism of which depends on morphological changes in a solid phase of the polymer under UV radiation.

Published: March 2024

This study investigates the effects of Zinc (4wt.%) and severe plastic deformation on the mechanical properties of AZ61 magnesium alloy through the stir-casting process. The severe plastic deformation (equal channel angular pressing (ECAP)) has been done followed by T4 heat treatment. The microstructural examinations revealed that the addition of 4wt.%Zn enhances the uniform distribution of β-phase, contributing to a more uniformly corroded surface in corrosive environments. Additionally, dynamic recrystallization (DRX) significantly reduces the grain size of as-cast alloys after undergoing ECAP. The attained mechanical properties demonstrate that after a single ECAP pass, AZ61 + 4wt.%Zn alloy exhibits optimal yield strength (YS), ultimate compression strength (UCS), and hardness. This research highlights the promising potential of AZ61 + 4wt.%Zn alloy for enhanced mechanical and corrosion-resistant properties, offering valuable insights for applications in diverse engineering fields.
Events Sequence Beyond mRNA Spike (S) Protein Vaccine and Long COVID: Simply Targeting Brain?
Authors: Altable Marcos
Published: March 2024

The intricate mechanisms of the immune response elicited by vaccines and the interplay between the immune system and the central nervous system (CNS) are poorly understood. This review explores these mechanisms, emphasizing the interplay between the immune system and the central nervous system (CNS). A critical aspect is the examination of how vaccine-induced immune responses can interact with the CNS, influencing neuroinflammation and neuroimmune interactions. Furthermore, the link between vaccination and persistent symptoms observed in long-COVID patients is discussed. Vaccination initiates a complex cascade of events, starting with the production of specific proteins, such as S1/S2 spike proteins, leading to robust immune activation in the axillary lymph nodes. The role of macrophages and antigen-presenting cells (APCs) in cytokine production, antigen presentation, and the stimulation of B and T cells highlights the sophistication of the adaptive immune response. The migration of immune cell-derived exosomes to the brain plays a dynamic role in CNS inflammation, neurodegenerative processes and long COVID. On the other hand, the prolonged presence of viral and vaccine-derived spike proteins may contribute to the complex pathophysiology of Long-COVID, shedding light on the delicate balance between beneficial immune responses and possible adverse neurological outcomes of vaccination. It is worth rigorous monitoring and further research to understand the mechanisms of neuroinflammation and the persistence of spike proteins and their long-term effects on the brain, emphasising the importance of a nuanced approach to vaccine safety and efficacy in the context of COVID-19 and beyond.Principio del formulario
Ubiquitous Gait Analysis through Footstep-Induced Floor Vibrations
Authors: Dong Yiwen , Noh Hae Young
Published: March 2024

Quantitative analysis of human gait is critical for early discovery, progressive tracking, and rehabilitation of neurological and musculoskeletal disorders, such as Parkinson’s Disease, stroke, and Cerebral Palsy. Gait analysis typically involves estimating gait characteristics, such as spatio-temporal gait parameters and gait health indicators (e.g., step time, length, symmetry, and balance). Traditional methods of gait analysis involve the use of cameras, wearables, and force plates, but are limited in operational requirements when applied in daily life - such as direct line-of-sight, carrying devices, and dense deployment. This paper introduces a novel approach for gait analysis by passively sensing footstep-induced floor vibrations during walking using vibration sensors mounted on the floor surface. Our approach is non-intrusive, scalable, and perceived as more privacy-friendly, making it suitable for continuous gait health monitoring in daily life. We developed a floor vibration-based gait analysis framework to estimate various gait parameters that are used as standard metrics in medical practices, including temporal parameters (step, stride, stance, swing, double-support, single-support time) and spatial parameters (step length, width, angle, stride length), and extracts gait health indicators (cadence/walking speed, left-right symmetry, gait balance, initial contact types). The main challenge is that floor vibrations are distinct across different floor types. To address this challenge, our approach develops floor-adaptive algorithms to extract floor-specific features and is designed to be generalizable to various settings, including homes, hospitals, and eldercare facilities. We evaluate our approach through real-world walking experiments with 20 adults with 12,231 labeled gait cycles across concrete and wooden floors. Our results show 90.5% (RMSE 0.08s), 71.3% (RMSE 0.38m), and 92.3% (RMSPE 7.7%) accuracy in estimating temporal, spatial parameters, and gait health indicators, respectively.
