Response solutions to harmonic oscillators beyond multi–dimensional brjuno frequency

This paper focuses on the quasi–periodically forced nonlinear harmonic oscillators \begin{document}$ \begin{equation*} \ddot{x}+\lambda^{2}x = \epsilon f(\omega t,x), \end{equation*} $\end{document} where \begin{document}$ \lambda \in \mathcal{O} $\end{document} , a closed interval not containing zero, the forcing term \begin{document}$ f $\end{document} is real analytic, and the frequency vector \begin{document}$ \omega \in \mathbb{R}^d \, (d \geq 2) $\end{document} is beyond Brjuno frequency, which we call as Liouvillean frequency. For the given class of the frequency \begin{document}$ \omega\in\mathbb{R}^{d}, $\end{document} which will be given later, we prove the existence of real analytic response solutions (the response solution is the quasi–periodic solution with the same frequency as the forcing) for the above equation. The proof is based on a modified KAM (Kolmogorov–Arnold–Moser) theorem for finite–dimensional harmonic oscillator systems with Liouvillean frequency.
Controls of Hyperglycemia Improves Dysregulated Microbiota in Diabetic Mice

Supplemental Digital Content is available in the text. Background. Type 1 diabetes (T1DM) is a chronic autoimmune disease characterized by T-cell–mediated destruction of insulin-producing beta cells. Evidence shows that patients with T1DM and mice used in specific diabetic models both exhibit changes in their intestinal microbiota and dysregulated microbiota contributes to the pathogenesis of T1DM. Islet transplantation (Tx) is poised to play an important role in the treatment of T1DM. However, whether treatment of T1DM with islet Tx can rescue dysregulated microbiota remains unclear. Methods. In this study, we induced diabetic C57BL/6 mice with streptozotocin. Then treatment with either insulin administration, or homogenic or allogenic islet Tx was performed to the diabetic mice. Total DNA was isolated from fecal pellets and high-throughput 16S rRNA sequencing was used to investigate intestinal microbiota composition. Results. The overall microbial diversity was comparable between control (nonstreptozotocin treated) and diabetic mice. Our results showed the ratio of the Bacteroidetes: Firmicutes between nondiabetic and diabetic mice was significant different. Treatment with islet Tx or insulin partially corrects the dysregulated bacterial composition. At the genus level, Bacteroides, Odoribacter, and Alistipes were associated with the progression and treatment efficacy of the disease, which may be used as a biomarker to predict curative effect of treatment for patients with T1DM. Conclusions. Collectively, our results indicate that diabetic mice show changed microbiota composition and that treatment with insulin and islet Tx can partially correct the dysregulated microbiota.
Weight (trans)itions: social support at the intersections of weight and identity online

ABSTRACT Though weight and weight-related issues have been explored prominently among the greater cisgender population and within other segments of the LGBTQ+ community, little has been done to explore such issues among transgender individuals. This study of online communities of support examines the role of narrative and narrative coping among transgender individuals seeking to lose or manage weight. Analysis reveals that individuals seeking support engage in three distinct processes of secondary threat appraisal: responsibility, obstacles to success, and fear and alignment. To mitigate and better navigate the tension of these threats, further analysis highlights the role that narrative plays in sensemaking and coping, both at an individual level and as a greater mechanism of communal coping and reciprocal support.
Numerical and machine learning analyses of entropy generation in an unsteady squeezing flow of copper/aluminum oxide/water hybrid nanofluid

Several studies have been carried out on the squeezing flow of mono‐nanofluids. However, this study investigates numerical and machine learning analyses of entropy generated in an unsteady squeezing flow of a copper–aluminum oxide/water hybrid nanofluid. Numerical analysis and the flow model simulation are done using the hybridization of Chebyshev pseudospectral and quasilinearization methods. The results show that the magnetic force is the most significant in the entropy generation number. A support vector machine learning model is introduced to calculate the average entropy generation number. The machine learning model's accuracy is measured using known performance metrics of regression models. The root mean square error is obtained as 4.1184, the mean absolute error as 1.8776, and the coefficient of determination ( R 2 ) as 0.995. Furthermore, the Hartman and Eckert numbers are identified to be highly positively correlated to the entropy generation number. However, for increasing values of the Hartman number, the temperature distribution between the two parallel plates decreases. We found that the temperature of copper/aluminum oxide/water nanofluid is greater than that of copper/water nanofluid, and the percentage difference between the temperature at the lower plate is estimated to be between 6% and 9% for H a ∈ [ 0 , 25 ] .
The effect of Remin Pro on the microhardness of initial enamel lesions in primary teeth: An in vitro study

Background: Remineralization is currently considered a treatment option for many clinicians. The present study was conducted to compare the effect of three remineralizing agents on microhardness of initial caries lesions in primary teeth. Materials and Methods: In this in vitro study, 96 enamel samples were prepared. Microhardness was first measured for all the samples using the Vickers microhardness test. After developing the initial caries lesions, the microhardness of all the demineralized samples was measured, and the samples were then divided into four groups (n = 24). Casein phosphopeptide–amorphous calcium phosphate in Group 1, Remin Pro in Group 2, and acidulated phosphate fluoride gel in Group 3 were placed on the samples for 4 min. The control group received no treatments. The microhardness of the samples was measured again following a pH cycle of 5 days. The data were analyzed by ANOVA and the post hoc test at the significance level of P < 0.05. Results: The mean microhardness reduced significantly in all the groups following the development of initial caries lesions and after the pH cycle of 3 days (P < 0.001). After the remineralization and pH cycle of 5 days, the mean microhardness was significantly lower in the control group compared to the other three groups (P < 0.001) and had increased in the three treated groups. The microhardness recovery rate also increased in the treated groups compared to the control group, but no significant differences were observed between the three groups themselves (P > 0.05). Conclusion: Remin Pro can be used as an effective substance for preventing tooth caries in children.

Refining Insights on the Impact of SES on Perceived Health: A Positive Health Perspective

BackgroundRecent insights and developments on health and society urge for a critical look at the positive relationship between socioeconomic status (SES) and health. We challenge the notions that it is sufficient to distinguish only between two groups of SES (low and high) and that only overall health is taken into account. MethodsA new grouping of SES was developed based on both income and education, resulting in six SES groups. Health was defined in terms of a new positive health concept, operationalised into six health dimensions generating a measure of total general health (TGH). Next, six socioeconomic and demographic determinants of health were included. Linear regression, T-tests and one-way ANOVA were applied to investigate the relationships in a Dutch sample. A subjective way to measure health was applied: self-rated health. ResultsFour out of six dimensions of health determined TGH: bodily functions, daily functioning, quality of life, and social and societal participation. Three out of six socioeconomic and demographic determinants impacted TGH: housing situation, age, and difficulties meeting financial obligations. While this is the general picture for the entire sample, there were interesting similarities and differences between the six SES groups. The similarities refer to the positive impact of the evaluation of bodily functions and daily functioning on TGH in all SES groups. The other dimensions affected TGH in some groups and some dimensions only in one SES group. None of the socioeconomic and demographic determinants affected TGH in all SES groups. New insights on health inequalities are provided. ConclusionsThe well-known positive relationship between SES and health is confirmed in this study. Further refining the health concept into six dimensions provides more detailed insights on which dimensions impact health the most. The subjective approach applied offers more refined information to better understand which health issues really matter to people. This yields new and more effective ways to develop interventions aimed at increasing healthy behaviour.
Financial Development and Economic Growth in Nigeria: New Evidence from a Threshold Autoregressive and Asymmetric Analysis

Financial development is concerned with policies, procedures and initiatives to increase the financial access, depth and productivity of financial institutions and financial markets. To that regards, this paper investigates the asymmetric relationship between financial development and economic growth by incorporating financial globalization uncertainty and inflation into a production function covering the Nigerian economy from 1980 – 2019. The threshold Autoregressive cointegration and nonlinear autoregressive distributed lag techniques are applied to examine the asymmetric cointegration between the variables, as well as the degree of the relationship among the variables. The results indicate long-run relationship between the parameters in the light of asymmetries. The asymmetric estimation results show that positive shock of financial development dampen economic growth. By comparison, symmetrically, the negative shock of the financial development improves the productivity growth of the Nigerian economy. Finally, while inflation shows a positive relationship, the financial globalization uncertainty indicates insignificant result. The implications of the said findings for productivity policies in Nigeria are also discussed. investigating the asymmetric relationship between financial development and economic growth by incorporating financial globalization uncertainty and inflation into a production function covering the Nigerian economy from 1980.
Effect of short video ads on sales through social media: the role of advertisement content generators

Abstract With the rapid development of e-commerce and social media in China, user-generated short video ads through social media have become very popular. However, the unique elements and phenomena for user-generated short video ads through mobile platforms have not yet been investigated. Therefore, a theoretical framework is proposed to explain the effect of user-generated social media short video ads on product sales from the perspective of advertisement sociability and vividness attributes, especially considering the moderation effect of advertisement content generators, including influencers, sellers and buyers. An empirical study using data from the Douyin platform and the Taobao e-commerce platform was conducted using dynamic panel models. The results indicate that the number of comments as one of the advertisement sociability attributes and female vividness and music vividness as two of the advertisement vividness attributes have consistently positive effects on product sales. The moderating effects of the influencer and the seller are positive for the effect of sociability on product sales, whereas the moderating effect of the buyer is positive for the effect of vividness on product sales. Thus, the best strategy to promote products through user-generated short video ads on mobile short video sharing platforms is for buyers to publish short video ads with music and a female or both a male and a female together; moreover, having a large number of comments increases product sales.
The effect of application of ethephon to processing tomato plants on the chemical composition of fruits.

Ethephon is used to accelerate fruit ripening on plantations with well-developed plants which have formed a large quantity of fruits. The aim of the study was to determine the effect of ethephon on the chemical composition of the fruits of seven cultivars of processing tomato (‘Rumba’, ‘Hubal’, ‘Sokal’ F1, ‘Mieszko’ F1, ‘Polset’ F1, ‘Hysioux’ F1 and ‘AF1120’ F1), applied to the plants when most of the fruits had reached the mature-green stage. The study was conducted during three consecutiveyears, characterized by different weather conditions. Meteorological elements, i.e. air temperature and precipitation totals, were monitored in the experimental station in Mydlniki, near Krakow, Poland. Ethephon was found to have a beneficial effect on the content of extract and soluble sugars of the harvested tomatoes and on their acidity. Dry matter and lycopene levels were not dependent on the use of this compound, while the ascorbic acid content was reduced by the procedure. The chemicalcomposition of the tomato fruits differed significantly in consecutive years of the study, which confirmed the weather impact on fruit quality and on the varied responses of different cultivars to use of ethephon. The tested cultivars were also compared in terms of their suitability for processing. The ‘Hubal’ cultivar had the highest content of dry matter, extract, soluble sugars of all the cultivars tested. The highest level of lycopene was noted for the tomatoes of the ‘Rumba’ and ‘Sokal’ F1 cultivar, ascorbic acid of the ‘Rumba’ and the highest acidity for ‘AF 1120’ F1.
Stress Testing Credit Risk: The Great Depression Scenario

By employing Moody’s corporate default and rating transition data spanning the last 90years we explore how much capital banks should hold against their corporate loan portfolios to withstand historical stress scenarios. Specifically, we will focus on the worst case scenario over the observation period, the Great Depression. We find that migration risk and the length of the investment horizon are critical factors when determining bank capital needs in a crisis. We show that capital may need to rise more than three times when the horizon is increased from 1year, as required by current and future regulation, to 3years. Increases are still important but of a lower magnitude when migration risk is introduced in the analysis. Further, we find that the new bank capital requirements under the so-called Basel 3 agreement would enable banks to absorb Great Depression-style losses. But, such losses would dent regulatory capital considerably and far beyond the capital buffers that have been proposed to ensure that banks survive crisis periods without government support.
The willingness to consume organic food: A review

ABSTRACT Giving the rising interest in naturally grown foods; several studies have contrasted various features of organic and conventionally grown foods in relation to consumer attitudes, perceptions, and preference for organic foods. This paper aims to explore consumers’ willingness to consume organic foods; the extent and attributes of consumer knowledge and awareness about organic food as well as consumer attitudes and preferences for organically grown foods. Articles from different peer review journals were used to develop this paper. The findings of this paper show that human health, food safety, attitudes and perceptions and willingness to pay for a price premium are some of the factors influencing consumers’ willingness to consume organic foods. Therefore, there is a need to create more awareness in the food industry relating to the health benefits of consuming organic foods.
GREEN SYNTHESIS AND CHARACTERIZATION OF ANTIMICROBIAL AND CATALYTIC SILVER NANOPARTICLES USING SOYMIDA FEBRIFUGA AQUEOUS LEAF EXTRACT

Green synthesis of nanoparticles has gained notable significance in the recent times because of the use of cost-effective and eco-friendly procedures. In the present study, one such simple, cost-effective and eco-friendly biosynthesis of silver nanoparticles [AgNPs] was developed. The synthesis of AgNPs from aqueous leaf extract of Soymida febrifuga was assessed by varying different reaction parameters like concentration of plant extract, the ratio of reactants, temperature and reaction time. Characterization using UV-Visible Spectrophotometry revealed a Surface Plasmon Resonance [SPR] peak at 429nm confirming the formation of AgNPs. Further, characterization of the AgNPs was carried out using X-Ray Diffractometer [XRD], Nanoparticle Analyzer, Scanning Electron Microscope [SEM] and Transmission Electron Microscope [TEM] which revealed the size, shape and crystallinity of the AgNPs formed. The Fourier Transform Infrared Spectroscopy [FTIR] study explained that biomolecules in Soymida febrifuga aqueous leaf extract have acted as the reducing and stabilizing agents during the synthesis. The in-vitro antimicrobial activity of the AgNPs was investigated against Bacillus subtilis, Escherichia coli, Klebsiella pneumoniae and Staphylococcus aureus. The catalytic activity of the AgNPs thus synthesized was investigated by studying the degradation of methylene blue dye by sodium borohydride. The AgNPs synthesized from aqueous leaf extract of Soymida febrifuga showed effective antimicrobial
Family influence on the nutritional status and eating habits of six to nine year-old children

ABSTRACT Objective To investigate whether caregivers’ attitudes, beliefs, practices, alimentary habits, and nutritional status influence the alimentary habits and nutritional status of children aged six to nine years. Methods This cross-sectional study included 164 children and a family member (caregiver) each (n=164), carried out in the family health units of the municipality of Ribeirão Preto (SP), Brazil. Weight and height measurements were performed; each child was then evaluated by the application of both the Child Feeding Questionnaire and 24h recall (for calculating the Healthy Eating Index Revised), in addition to the assessment of adherence to healthy eating steps of the Ministry of Health, through a questionnaire. Results The results showed that the prevalence of being overweight was 18.3% in children and 32.9% in caregivers, and the prevalence of obesity was 15.9% and 37.9%, respectively. Most of the 56 children categorized as overweight also had overweight caregivers (82.1%; n=46). Concerns regarding children’s weight control were higher among caregivers responsible for overweight children (3.6±1.29). In contrast, caregivers responsible for children below or at normal weight demonstrated a greater tendency toward getting children to eat (3.3±0.97 and 3.9±0.99, respectively). The average score; of the children’s Brazilian Healthy Eating Index Revised (50.0±13.6) was similar to that of their caregivers (56.5±12.1). Conclusions Caregivers have a direct influence on the nutritional status and eating habits of children; therefore, they should be targeted in the processes of nutritional intervention for the prevention and treatment of childhood obesity.
Designing and Fine Tuning a Fire Safety Monitoring System for Smart Buildings using RPL Protocol

Internet of Things is a well established technology for a wide variety of applications like Smart Homes, Smart Buildings, Healthcare, Agriculture, Aviation, AMI etc. Fire tragedy is one of the most damaging risk that could occur for an industrial, commercial or residential building. IoT can be successfully employed in large buildings to safeguard the occupants and also its infrastructure. To this end, a smart building is equipped with large number of economic sensors that forms an LLN (low power lossy network) with border router for Internet connectivity. RPL is a routing protocol for LLNs that ensures that tiny battery operated sensor devices could form a network with automated address configuration, spontaneous topology formation, IPv6 connectivity and fail-safe operation. This paper proposes an enhanced application of RPL protocol which increases the longevity of the portable nodes and assures quick response during a fire. This paper explains the required IoT infrastructure along with an application that provides a live web page with color codes to monitor the temperature of the different regions of a smart building.
Comparative Study Between the Efficacy of Microneedling Combined with Trichloroacetic Acid Versus Microneedling with Tacrolimus in the Treatment of Stable Vitiligo

Background: Many treatment options were used for Vitiligo. But there is no consensus on the precise treatment modality. Aim of the work: The study aimed to assess and compare the efficacy of microneedling combined with trichloracetic acid [TCA] versus micro-needling with tacrolimus in the treatment of Vitiligo, Patients and Methods: 60 Vitiligo were included and classified into two equal groups. Group [A] included 30 patients who received micro-needling with dermapen then tacrolimus 0.03 ointments every two weeks for six sessions. Group B included thirty patients who received micro-needling with dermapen then TCA 25% every two weeks for six sessions. The outcome was documented. Results: The repigmentation was slightly higher in TCA-treated patches than with tacrolimus. Excellent response in repigmentation occurred in 43.3%of TCA patches. In contrast, in 16.7% of tacrolimus-treated patches, Good improvement occurred in13.3% of TCA-treated patches while 23.3% of tacrolimus-treated patches. Moderate improvement occurred in10.0% TCA -treated patches while 30.0% of tacrolimus-treated patches, mild improvement occurred in 13.3% of TCA -treated patches. In comparison, only in 16.7% of tacrolimus-treated patches, However, there was a great difference between the two drugs regarding erythema, inflammation, and exfoliations, which occurred mainly with TCA. Conclusion: The mix of microneedling with either TCA 25% or tacrolimus is effective and safe in treating Vitiligo. However, TCA achieved a slightly increased percentage of repigmentation than tacrolimus.
