Continuous biframes in Hilbert Spaces

In this paper, we present the concept of continuous biframes in a Hilbert space. We examine the essential properties of biframes with an emphasis on the biframe operator. Moreover, we introduce a new type of Riesz bases, referred to as continuous biframe-Riesz bases

Representations of gg-fusion frames in Hilbert C∗C^{\ast}-Modules

In this paper, we provide some generalization of the concept of fusion frames following that evaluate their representability via a linear operator in Hilbert $C*$-module. We assume that $\Upsilon _\xi$ is self-adjoint and $\Upsilon _\xi(\frak{N} _\xi)= \frak{N} _\xi$ for all $\xi \in \mathfrak{S}$, and show that if a $g-$fusion frame $\{(\frak{N} _\xi, \Upsilon _\xi)\}_{\xi \in \mathfrak{S}}$ is represented via a linear operator $\mathcal{T}$ on $\hbox{span} \{\frak{N} _\xi\}_{ \xi \in \mathfrak{S}}$, then $\mathcal{T}$ is bounded. Moreover, if $\{(\frak{N} _\xi, \Upsilon _\xi)\}_{\xi \in \mathfrak{S}}$ is a tight $g-$fusion frame, then $\Upsilon_\xi$ is not represented via an invertible linear operator on $\hbox{span}\{\frak{N} _\xi\}_{\xi \in \mathfrak{S}}$, We show that, under certain conditions, a linear operator may also be used to express the perturbation of representable fusion frames. Finally, we'll investigate the stability of this fusion frame type

Toward a self-learned Smart Contracts

In recent years, Blockchain technology has been highly valued and disruptive. Several researches have presented a merge between blockchain and current application i.e. medical, supply chain, and e-commerce. Although Blockchain architecture does not have a standard yet, IBM, MS, AWS offer BaaS (Blockchain as a Service). In addition to the current public chains i.e. Ethereum, NEO, and Cardeno; there are some differences between several public ledgers in terms of development and architecture. This paper introduces the main factors that affect integration of Artificial Intelligence with Blockchain. As well as, how it could be integrated for forecasting and automating; building self-regulated chain.Comment:

Innovative Nutrition Education: A Color-Coded Tool for Individuals with Low Literacy Level

Background: The food exchange system was developed to serve as an educational tool in helping individuals plan their own meals. This study aimed to develop a friendly-user food exchange list for individuals with a low literacy level; (2) Methods: A two-group, pre-test/post-test research study aimed to develop a friendly-user food exchange list for individuals with a low literacy level. Thirty female workers of low literacy were recruited. Participants were divided into two groups. Group one was taught how to use the standard exchange system, while group two was taught how to use the modified exchange system. Each participant was assigned a task of prepare a meal with a specified caloric content and macronutrient distribution. The task was assigned before and after the exchange list education session. Groups’ differences were tested using the chi-square test, and the analysis of variance (ANOVA); (3) Results: A higher percentage of participants in group two were able to plan daily diets that achieved the recommendations of fruits (p = 0.02), protein (p = 0.03), dairy (p < 0.001), carbohydrates (p < 0.001), and calories (p < 0.001). Moreover, diet plans prepared by group two had a higher healthy eating index (p < 0.001) when compared to diet plans prepared by group one. The modified exchange lists are a friendly-user tool that can be implemented for individuals with low literacy, since it relies on visual techniques.QU research grant QUST-1-CHS-2022-471

How are sex-gender differences in chair-and-desk-based postural variability explained? A scoping review

Background: Desk-work-related musculoskeletal pain is more prevalent among female workers than male workers. This may be contributed to by sex and/or gender differences in postural variability however, the mechanisms underpinning these differences are poorly understood. This review investigates whether desk-based postural variability studies investigate sex-gender differences and, how they explain the mechanisms behind these differences. Methods: A scoping review was conducted with four databases (PubMed, Embase, Scopus and ProQuest) searched in June and July 2023. Studies investigating postural variability among desk-based workers were included and a narrative approach used to synthesise results. Results: 15 studies were included. Only four reported on sex-gender differences. None collected psychological or social information to explore reasons for sex-gender differences. Conclusion: The mechanisms behind postural variability differences between sexes and genders are complex and multifactorial. Studies largely do not consider sex and gender and do not collect the information necessary to explain their results.The author(s) reported there is no funding associated with the work featured in this article.

ASSESSMENT OF DIETARY HABITS, PHYSICAL ACTIVITY, LIFESTYLE, AND OTHER RISK FACTORS OF NONALCOHOLIC FATTY LIVER DISEASE AMONG ARAB ADULTS LIVING IN QATAR

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is defined as an abnormal accumulation of triglycerides in the liver. It is the most common chronic liver disease globally and is linked to features of the metabolic syndrome including obesity, type 2 diabetes (T2DM), hypertension, and hyperlipidemia. MASLD outcomes are largely affected by dietary habits, lifestyle behaviors, physical activity, or a combination of any. Aim: The aim of this cross-sectional study is to evaluate dietary diversity and habits, physical activity levels, lifestyle behaviors, and evaluate potential associations with MASLD indicators in Arab adults residing in Qatar. Methods: A descriptive cross-sectional study was carried out to meet the study's main objective. A total of 94 participants were included. Demographics, health, lifestyle, and dietary habits were assessed through the Participant's Personal and Dietary Habits Information Questionnaire. Dietary diversity was estimated using the Food Groups Consumption (FGC) score. Physical activity and sleep were assessed through the Seven-Day Physical Activity Recall (7-day PAR) form. Descriptive statistics and linear regression were performed to analyze data and assess any associations between indicators of MASLD (BMI, lipid profile, liver enzymes, and glucose levels) and dietary habits. Results: The findings of the study showed an association between BMI and snacking (Ptrend= 0.049). There was an association between first meal timing and total cholesterol (Ptrend= 0.045), low-density lipoprotein (Ptrend= 0.047) and fasting blood sugar (Ptrend= 0.026). We also found an inverse association between last meal timing and high-density lipoproteins (Ptrend= 0.007). Additionally, an association was detected between triglycerides and both excluded meals (Ptrend= 0.010) and eating out (Ptrend=0.002). All participants were found to have adequate dietary diversity (FGC score of 101.9), with no differences between food group intakes except for males consuming more fruit than females (P= 0.042). Physical activity was also assessed for the last seven days, and female participants were found to have a significantly higher level of hours of moderate-intensity exercise during the weekdays (P= 0.014) and weekends (P= 0.026), and significantly more total MET-minutes of moderate-intensity physical activity than males (P= 0.011). Conclusion: Dietary habits such as snacking, meal skipping, meal timings, and eating out are associated with MASLD anthropometric and biochemical indicators. This research provided suggested insights on dietary habits that may be associated with MASLD and sets the bar for larger studies with more robust study designs to be done in Qatar

Douglas' Factorization Theorem and Atomic System in Hilbert Pro-C∗C^{\ast}-Modules

In the present paper, we introduce  the generalized inverse operators, which have an exciting role in operator theory. We establish Douglas' factorization theorem type  for  the Hilbert pro-$C^{\ast}$-module.We introduce the notion of atomic system and $K$-frame in the Hilbert pro-$C^{\ast}$-module and study their relationship. We also demonstrate some properties of the $K$-frame by using Douglas' factorization theorem.Finally  we demonstrate that the sum of two $K$-frames in a Hilbert pro-$C^{\ast}$-module with certain conditions is once again a $K$-frame

Intended and Unintended Benefits of Folic Acid Fortification—A Narrative Review

Inadequate folate intake during pregnancy is the leading cause of the development of neural tube defects (NTDs) in newborns. For this reason, mandatory fortification of folic acid, a synthetic, easily bioavailable form, in processed cereals and cereal products has been implemented in the US since 1 January 1998 to reduce the risk of NTD in newborn children. This report aimed to review the literature related to the impact of mandated folic acid fortification on the intended and unintended benefits to health. Potential adverse effects were also discussed. We searched Pubmed, Google Scholar, Embase, SCOPUS, and Cochrane databases for reports. About 60 reports published between January 1998 and December 2022 were reviewed, summarized, and served as background for this review. The intended benefit was decreased prevalence of NTDs, while unintended benefits were reduction in anemia, blood serum homocysteine, and the risk of developing cardiovascular diseases. Potential issues with folic acid fortification are the presence of unmetabolized folic acid in circulation, increased risk of cancer, and the masking of vitamin B-12 deficiency. From a health perspective, it is important to monitor the impact of folic acid fortification periodically
