The approach to patient clustering based on the microchip data confined to distinct loci using the combinations of variants
Authors: Iulmetova LN , Kulemin NA , Sharova EI
Published: February 2023

Fuchs' endothelial corneal dystrophy is a socially significant hereditary disease. More than a half of cases in the European population are caused by the increased number of trinucleotude repeats in the TCF4 gene. The study was aimed to develop and test the approach of dividing patients into groups based on the chip-based genotyping and genome-wide association study (GWAS) results. The analysis was conducted using FECD Genetics Multi-center Study and AREDs project datasets containing the data of 1721 clinical cases and 2408 control patients. When analyzing the GWAS results, the patients and the control group were divided into two groups by means of hierarchical clustering suggesting that patients with the increased number of repeats in the TCF4 gene are carriers of specific combinations of genomic variants (haplotypes). It was shown that individual variants cannot be used for the molecular genetic stratification of patients with the increased number of repeats in TCF4 due to inconsistent results obtained for the variants. Furthermore, the haplotype-based approach outperformed the SNPs in terms of odds ratio. The paper proposes a method that enables further search for the biologically relevant combinations of genomic variants.

Content of proselytizing at receptions differently. Da'wah content on social media is a negotiation process. Da'wah's content shows the potential position of postmillennial netizens as active meaning. They are free to choose proselytizing content. This research uses a qualitative method with an interpretive approach. The data were analyzed to find the postmillennial netizens' reception pattern. This research was conducted at State Islamic Religious universities in South Sulawesi Province. There are three groups in the reception of proselytizing content on social media. Firstly, netizen postmillennial oppositional position. In this group, postmillennial netizens are inconsistent in particular groups but watch a variety of messages and preachers. In this group, netizens examine religious concepts from multiple sources. The second negotiated position of this group is postmillenial netizens fanatical on certain mubaligh but still, put tabayyun on certain mubaligh. A third hegemonic position is a militant group without putting forward the principle of tabayyun. However, in this study, social media is a medium that offers various types of preaching and different proselytizing messages. So, some netizens experience the hybridization of proselytizing messages. But some netizens do not experience hybridization of religious understanding because they only watch certain mubaligh.
The trends and determinants of seasonal influenza vaccination after cardiovascular events in Canada: a repeated, pan-Canadian, cross-sectional study
Authors: Cho Hanna , Houle Sherilyn K. D. , Alsabbagh Wasem
Published: February 2023

Introduction

Annual influenza vaccination is recommended for individuals with a history of cardiovascular disease (CVD) events. We aimed to examine (1) the time trends for influenza vaccination among Canadians with a CVD event history between 2009 and 2018, and (2) the determinants of receiving the vaccination in this population over the same period.

Methods

We used data from the Canadian Community Health Survey (CCHS). The study sample included respondents from 2009 to 2018 who were 30 years of age or more with a CVD event (heart attack or stroke) and who indicated their flu vaccination status. Weighted analysis was used to determine the trend of vaccination rate. We used linear regression analysis to examine the trend and multivariate logistic regression analysis to examine determinants of influenza vaccination, including sociodemographic factors, clinical characteristics, health behaviour and health system variables.

Results

Over the study period, in our sample of 42 400, the influenza vaccination rate was overall stable around 58.9%. Several determinants for vaccination were identified, including older age (adjusted odds ratio [aOR] = 4.28; 95% confidence interval [95% CI]: 4.24–4.32], having a regular health care provider (aOR = 2.39; 95% CI: 2.37–2.41), and being a nonsmoker (aOR = 1.48; 95% CI: 1.47–1.49). Factors associated with decreased likelihood of vaccination included working full time (aOR = 0.72; 95% CI: 0.72–0.72).

Conclusion

Influenza vaccination is still at less than the recommended level in patients with CVD. Future research should consider the impact of interventions to improve vaccination uptake in this population.

2009年10月，中研院院士許倬雲（1930—）在臺灣大學演講時曾經表示，期望未來學界將“東亞”當成研究重點，以與西方文化進行互補融合。東亞研究包含諸多面向，但核心觀念在於肯定名之爲“東亞”的中國、日本、韓國、馬來半島等地，彼此有地緣關係，又具有文化傳播歷史的相似性，應分享某些成份；並具有一定而能夠承載各自相異、而又具有整體性的文化意涵，俾能與歐美相對並馳。在這種脉絡下，“經典詮釋”是一個重要的研究途徑。誠然，中國以儒家經典爲首的知識體系，在東亞歷史中扮演著推動文明發展的重要角色；不過，中國以外的區域也不全然被動接受經典本身與傳統的解釋，仍有從其自身歷史文化脉絡出發，而作出具有特色的詮釋的情形，可謂一種站在同一經典的平台上與中國對話的表現。研究東亞的經典詮釋進路，若能深入他國的歷史脉絡，在探討經典地位的同時，也瞭解其獨特的融通運用，一方面能避免落人純粹以中國爲中心，而將周邊地域貶爲缺乏主體性之他者的危險；另一方面在歷史研究上，能夠探索東亞地區文化思想的形成過程，在思想研究上則能開顯經典意涵的多元風貌，而能夠達成建構具有自身特色，如許倬雲院士所言，能與西方進行對話的東亞文化研究目標。(撮要取自內文首段)

The Benefit of Inflation-Indexed Debt: Evidence from an Emerging Bond Market
Authors:   Bank of the Republic of Colombia, Cardozo Cristhian Hernando Ruiz , Christensen Jens H. E. ,   Federal Reserve Bank of San Francisco
Published: February 2023

Portfolio diversification is as important to debt management as it is to asset management. In this paper, we focus on diversification of sovereign debt issuance through greater reliance on inflation-indexed bonds for a representative emerging economy, Colombia. Using an arbitrage-free dynamic term structure model of fixed-coupon and inflation-indexed bond prices, we account for inflation and liquidity risk premia and calculate the net benefit of issuing inflation-indexed bonds over nominal bonds. Our results suggest that the Colombian government could lower its funding costs by as much as 0.69 percent by increasing its issuance of inflation-indexed debt, in particular at long maturities.

Authors: Krynke Marek , Mielczarek Krzysztof
Published: February 2023

The article analyzes the safety aspects related to the construction and operation of a mobile crane. The load-bearing capacity of the boom sub-assembly rotation node was tested in a mobile crane. When identifying the load, the uneven compliance of the supporting components was taken into account. The considerations are illustrated with an example of a mobile crane slewing bearing with a lifting capacity of 50 tons. The basic problems of building the computational model are discussed and the results of the load bearing capacity of the slewing ring bearing for different positions of the load-bearing component of the tested machine are presented. An analysis of the load of the rolling elements in a slewing ring bearing was carried out and the reasons for changes in the load capacity in relation to the methods of calculating the load capacity, assuming non-deformability of the bearing rings, were indicated. It has been shown that deformations of the supporting frames are so large that they significantly change the distribution of forces transmitted by individual bearing rollers.
Recycling of Asbestos-Cement Waste – An Opportunity or a Threat?
Authors: Brycht Natalia
Published: February 2023

Asbestos-cement waste from roof coverings and facades are classified as hazardous materials and should be successively removed from buildings. The current management of these wastes is limited to their controlled depositing in landfills, which does not ultimately solve the problem of their impact on the environment in the future. The article presents the current state of disposal of asbestos in Poland, with particular emphasis on the Silesian Voivodeship. The literature reports on the methods of neutralizing this type of waste and the possibility of their recycling were analyzed. It was found that the most popular way of recycling asbestos waste is thermal treatment, and the least effective - chemical treatment. Unfortunately, legal barriers prevent the spread of these solutions in the country in practice, despite the fact that safe methods of recycling asbestos-cement products are known.

The Influence of Material Configuration of Fibre-Metal Laminates with Alumina Core on Flexural Strength
Authors: Frankiewicz Mariusz , Karoluk Michał , Dziedzic Robert , Timmel Tristan , Scholz Peter
Published: February 2023

Fibre metal laminates (FMLs) consisting of layers made of PA6 polyamide prepregs reinforced with glass and carbon fibres and an aluminium alloy core are the new variant of the other types used by aerospace FML materials such as GLARE or CARALL. By using a thermoplastic matrix, they can be shaped by stamping processes, which allows for a more efficient production process than classical laminating methods such as vacuum bagging. In addition to the improved impact energy absorption efficiency, the metallic core can be utilised to effectively bond the composite part to adjacent metallic structures. This article presents the influence of the material configuration of fibre-metal laminates consisting of continuous fibre-reinforced thermoplastic outer layers integrated with a layer of metallic aluminium alloy inserts—a number of layers, type and direction of reinforcing fibres—on the static and fatigue flexural properties. In this study, eight laminate configurations were prepared using a one-step variothermal consolidation process. The results showed that in the three-point flexural fatigue test, the samples exceeded 106 cycles at stresses <30% of the static bending strength. Laminates with predominantly longitudinally reinforced layers showed the highest fatigue strength among the FML samples analysed. The type of reinforcing fibres and the number of layers were less affected on the analysed mechanical properties.

Authors: Romagnoli Francesco , Thedy Alessandro , Ievina Baiba , Feofilovs Maksims
Published: February 2023

Microalgae cultivation at biogas plants creates joint benefits for using liquid digestate and exhaust gas from the CHP unit as nutrient and carbon sources for microalgae growing. This circular approach increases biogas production’s sustainability towards a bioeconomy and zero-waste perspective. This study aims to evaluate the potential environmental impacts in connection to a novel microalgae growing technology named Stacked Modular Open Raceway Pond (SMORP) as a side-stream process coupled with centrate and exhaust gases from a biogas plant. A comparative LCA according to ISO 14044 is performed between the innovative SMORP concept at the pilot level and a hypothetical scaled-up system. Primary data for the inventory are directly gathered from the microalgae growing test performed at the biosystems laboratory of the Institute of Energy Systems and Environment of the Riga Technical University. Secondary data are collected from literature mostly in terms of mass and energy balances considering the SMORP pilot project design. The results of the LCA include the main findings both at mid and endpoint categories according to the IMPACT 2002+ method. In addition, a sensitivity analysis for several different parameters has been investigated. Results show the feasibility of the coupled system and the possibility of having benefits once the system is scaled up. Nevertheless, the results show a critical dependency of the environmental performance on the local conditions, potentially affecting too high cultivation costs.

Objetivo: Avaliar o potencial antibacteriano frente a microrganismos humanos potencialmente patogênicos do extrato etanólico e frações de Copernicia prunifera. Metodologia: A triagem fitoquímica de plantas foi realizada usando métodos de precipitação e coloração e a atividade antibacteriana utilizando o método de difusão em disco e microdiluição em caldo contra cepas padronizadas de Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa e Staphylococcus aureus. Resultados: A triagem fitoquímica revela a presença de taninos, flavonoides, esteroides, triterpernóides, saponinas e alcaloides. Os extratos etanólico e frações da casca do caule e folhas tiveram atividade inibitória contra S. aureus e K. pneumonie com zona de inibição que variou de 7,0±1,73 a 9,33±0,58 mm pelo método de difusão em disco. Pelo método de microdiluição em caldo os extratos foram satisfatórios somente contra K. pneumoniae (CIM = 125 a 1000 µg/mL) S. aureus, P. aeruginosa e E. coli se mostraram resistentes aos testes (CIM > 1000 µg/mL). Conclusão: Esses resultados fornecem uma base para futuras investigações em modelos in vivo, para que os compostos de C. prunifera possam ser aplicados no desenvolvimento de novos agentes antimicrobianos contra K. pneumoniae.

Introdução: A suplementação nutricional em pessoas vivendo com HIV ainda é pouco difundida, sendo essencial o levantamento de evidências que apontem as terapêuticas mais eficientes para beneficiar a saúde desta população. Ao se tratar do público infantil, no qual a prevalência de carências nutricionais é elevada, o conhecimento acerca da suplementação nutricional é bastante profícuo. Objetivo: Analisar relatórios de pesquisa acerca dos efeitos do uso de suplementos nutricionais em crianças vivendo com HIV. Desenho do estudo e local: Uma revisão narrativa realizada na Universidade Federal do Maranhão, em Imperatriz, município localizado no oeste do estado do Maranhão. Método: Foi realizada uma busca nos bancos de dados Cochrane, PubMed, Scopus, WHO/OMS e biblioteca digital de teses e dissertações da USP entre setembro de 2021 a janeiro de 2022. Resultados: Foram incluídas 26 produções, as quais demonstraram que o uso de múltiplos nutrientes reduziu o tempo de hospitalização em crianças admitidas com diarreia ou pneumonia, melhorando a morbidade, concentração de hemoglobina e ganho ponderal. A oferta de ferro foi considerada satisfatória no combate à progressão da doença, vitamina A melhorou o quadro de diarreia persistente e vitamina D a habilidade motora neuromuscular. Conclusão: Os estudos sobre suplementação nutricional e a relação dos nutrientes com os diversos aspectos de saúde das crianças vivendo com HIV tem avançado. Logo, é necessário alargar as pesquisas no tema em contextos distintos, a fim de incrementar e gerar novas evidências, colaborando para uma conduta mais assertiva dos profissionais de saúde e consequente melhora no prognóstico dessas crianças.

A conquista de uma vaga em um curso superior é um momento de grande realização, porém várias mudanças e dificuldades permeiam a trajetória acadêmica. Esta pesquisa objetivou avaliar a qualidade de vida dos acadêmicos do curso de enfermagem e de medicina de uma universidade pública. Utilizou-se o método quantitativo, descritivo e transversal, realizado com 272 acadêmicos de enfermagem e de medicina. A coleta de dados utilizou um questionário sociodemográfico e o instrumento WHOQOL-bref. As análises foram realizadas por meio de frequência absoluta e relativa. Constatou-se que houve predomínio do sexo feminino (72,1%), faixa etária até 22 anos (48,9%), não tabagistas (94,1%) e originários(as) de outros municípios (92,6%). Além disso, 92,3% estão satisfeitos com o curso, 97,1% se identificam com o curso, 90,4% mantinham-se financeiramente com a ajuda de familiares, 66,5% realizavam atividades extracurriculares e 71,0% vivenciaram algum evento marcante na vida no último ano. Tanto para a totalidade de participantes, quanto para os cursos separadamente, o Domínio Psicológico demonstrou menor média no escore, enquanto o Domínio Meio Ambiente foi o que apresentou maior média no escore, quando comparados aos demais domínios do instrumento. Concluiu-se que as instituições de ensino devem atentar-se aos aspectos que envolvem a área psíquica dos acadêmicos, implementando ações que auxiliem e promovam a melhoria da qualidade de vida desta população.

Introduction: Hericium erinaceus (HE), often known as Lion's Mane, is an edible fungus that has been extensively explored for its many functions. The use of this mushroom in traditional Chinese medicine dates back many years, and it is now being tested in the treatment of cognitive decline and Alzheimer's disease, and mental diseases like depression, anxiety, schizophrenia. Methods: We followed 2020 PRISMA statement for systematic reviews. The three selected databases were Worldcat®, Cochrane Library®, and PubMed®. On March 7, 2022, a search for articles was conducted. The search sources' descriptions were Hericium erinaceus AND (mental disorders OR cognitive impairment OR depression OR anxiety). "English" was the sole filter applied to the data sources. Results: Three Japanese randomized double-blind controlled trials were included in the review. Although the data demonstrated that HE can be useful in treating symptoms of cognitive impairment and moderate cognitive impairment, it was not effective in treating depression/anxiety symptoms. Conclusions: More studies are needed in countries besides Japan, lasting at least 12 weeks, since shorter periods do not demonstrate significant improvement of symptoms. Incorporating HE into a patient's daily diet may produce favorable benefits by alleviating cognitive decline.

Gradient-Based Optimization of Chaotic Panel Flutter
Authors: Stanford Bret K.
Published: February 2023

This work considers the gradient-based optimization of an aeroelastic panel structure undergoing chaotic vibrations. A previously presented adaptive time-marching scheme is used to stabilize the design sensitivities that would normally grow unbounded in time, owing to intermittent unstable eigenvalues of the Jacobian. The design optimization entails forcing the root mean square (RMS) of the panel vibration to some specified value, in a way that minimizes the deviation of the structural thickness variables from their uniform baseline values. Depending on the location of the RMS constraint, the output physics may be chaotic, limit cycle oscillations, or statically buckled.
Simple, Fast Nitric Oxide Planar Laser-Induced Fluorescence Model for Computational Fluid Dynamics Applications
Authors: Drozda Tomasz G. , Ground Cody R. , Knapp Walker T. , Danehy Paul M.
Published: February 2023

The current work demonstrates the efficacy of a simple and fast model for nitric oxide (NO) laser-induced fluorescence (LIF). The model is validated with experimental LIF spectra computed from captured images of fluorescence from a gas cell filled with a known amount of NO. These data are obtained for several segments of the NO fluorescence spectrum. The selected segments encompass LIF lines with rotational quantum numbers appropriate for low-to-moderate temperature flows. The spectra obtained using the current model are also compared to those obtained from other theoretical models, namely, LIFBASE and LINUS. The current model is based on a previously developed version of a two-level fluorescence model and is developed specifically for applications in computational fluid dynamics (CFD) where rapid on-the-fly evaluations are required due to the potentially large number of grid cells for which LIF is being computed. Good agreement between the experimental and theoretical results provides confidence in current LIF modeling for use with CFD. An example application of the current model in a Mach 6.5 hypersonic mixing flowfield is also presented.
Equivalent Area Targets for Inverse Design Optimization with Changing Low-Boom Cruise Conditions
Authors: Li Wu
Published: February 2023

This paper provides theoretical and numerical justifications for inverse design optimization of reversed equivalent area [Formula: see text] of low-boom supersonic aircraft when the cruise condition changes during optimization iterations. A modified linear theory for steady flow around a supersonic projectile is used to establish the accuracy of [Formula: see text] body-of-revolution approximation of a low-boom supersonic aircraft for undertrack sonic-boom analysis using computational fluid dynamics off-body pressure. As a result, designing a low-boom shape of the off-body pressure at three body lengths below the aircraft is equivalent to designing a low-boom [Formula: see text] shape. A Bezier curve with eight control points is used to define an [Formula: see text] target for inverse design optimization of [Formula: see text] of a supersonic aircraft. To make an [Formula: see text] target matchable by a low-boom supersonic aircraft, the [Formula: see text] target must have the minimal perceived level of decibels (PLdB) for sonic boom and satisfy two constraints defined by the cruise condition, effective length, and two nondimensional parameters. Numerical results are used to verify that, for different cruise conditions, all optimized [Formula: see text] targets with PLdB below 70 can be approximately generated by scaling one of them if the targets have the same nondimensional parameters and approximately the same effective length.
