Some Fuzzy Least Squares Estimators for Regression Model Using Different Kernel Functions
Authors: Ibrahim Tawfeeq* Areej , Hazim Aboudi Emad 
Published: September 2024

This paper presents a method for addressing the issue of outliers in fuzzy data. The method involves calculating a new distance between fuzzy numbers using various kernel functions, based on the fuzzy least squares method. The parameters of the fuzzy regression model were estimated in cases where the explanatory variables were non-fuzzy, the parameters were fuzzy, and the response variable was both fuzzy and an outlier. These estimators were then compared to the Fuzzy Least Squares method (FLS) using Mean Square Error (MSE) through simulations with different sample sizes (25, 50, 100, 150) and levels of outliers (0, 0.10, 0.20, 0.30). The results showed that this method, utilizing the new distance, achieved the best results in the presence of outliers.

The Role of the Iraq Stock Exchange in Creating Government Fiscal Space: A Forward-looking Perspective
Authors: Inaam Majeed Abdul Hussein  , Ali Hussein Safaa 
Published: September 2024

The stock market is one cornerstone of an economy, and relying on limited financial resources in any country has become increasingly challenging. Recognizing the significance of the financial market in bridging the financing gap in the economy, most countries have acknowledged its pivotal role, especially in the aftermath of numerous global financial crises. This acknowledgement involves mobilizing savings from surplus entities to deficit entities and channeling them into various investments by issuing financial instruments such as stocks, bonds, and government securities. Consequently, the financial market provides liquidity and cash flow, creating a fiscal space that can be utilized to fund developmental investment projects without the need for external borrowing and the associated risks of high interest rates on loans, which can impact the government's ability to repay. Therefore, the primary objective of this study is to analyze the reality of the Iraqi securities market (ISX) using financial market indicators and the government's ability to leverage the financial market to generate high financial, which Iraq's government needs. Thereby expanding the government's Fiscal space. The research revealed that the Iraqi securities market (ISX) needs more capacity to diversify its financial sources and attract local and international investments. Additionally, there is an almost complete absence of the issuance of government securities, which could contribute to creating the government's Fiscal space.

A comparison between Speckman and Bayesian estimation method of a semiparametric balanced longitudinal data model
Authors: Abdulsamad Habeeb   * Ahmed , N. Nayef Al-Kazaz Qutaiba 
Published: September 2024

This paper aims to use semi-parametric regression to balanced longitudinal data model, where the parametric regression models suffer from the problem of strict constraints, while non-parametric regression models, despite their flexibility, suffer from the problem of the curse of dimensionality. Consequently, semi-parametric regression is an ideal solution to get rid of the problems that parametric and non-parametric regression suffer from. The great advantage of this model is that it contains all the positive features included in the previous two models, such as containing strict restrictions in its parametric component, complete flexibility in its non-parametric component, and clarity of the interaction between its parametric and non-parametric components.
Based on the above, two methods were used to estimate a semi-parametric balanced longitudinal data model. The first is the Bayesian estimating method; the second is the Speckman method, which estimated the unknown nonparametric smoothing function by employing the kernel smoothing Nadaraya-Watson method. The Aim was to make a comparison between the Bayesian estimation method and the classical estimation method. Three different sample sizes were used in the simulation studies: 50, 100, and 200. The study results showed that the Bayesian estimating method is best at low variance levels (1,5), whereas the Speckman method is best at high variance level (10).

Published: September 2024

Wood carving has been an integral part of many ethnic groups in Ghana and worldwide. Currently, Ghanaian wood carvers produce countless varieties of wooden sculptures for tourist trade or export. The wood carving business in Vakpo has provided employment for natives in the production of different wooden objects such as stools, umbrella tops, linguist staffs, walking sticks, human and animal figures/figurines, and many more. Unlike any other wood carving industry, one of the major challenges facing Vakpo traditional wood carving is less recognition by art lovers due to scanty literature in the town and insufficient art enthusiasts in Ghana. The study adopts a qualitative research design with a descriptive research method. The data was gathered through observations and interviews. The results indicate that wood carvers in Vakpo exhibit mastery in creativity, intricate cuts as well as finishing, and their quality wood carvings are by no means inferior to the wooden sculptures of other wood carvers from renowned towns such as Aburi, Ahwiaa, Foase, and others.

Authors: Salim M. , Dutta B. 
Published: September 2024

This research aims to define and investigate the properties of semiprime hyperideals in ternary hypersemirings. The researchers introduce the notion of semiprime hyperideal in a ternary hypersemiring and characterize it. The study has expanded by introducing the ideas of weak n-system and strong n-system in a ternary hypersemiring, and using these; the researchers characterize semiprime hyperideals. Again, the researchers introduce the prime radical β(I) of a hyperideal I in a ternary hypersemiring and obtain the important result that for a proper hyperideal of a ternary hypersemiring R, β(I) ={r ∈ R: every weak m-system in R which contains rhas a nonempty intersection with I}. Finally, the work has been concluded by introducing the concept of fully idempotent ternary hypersemirng, and using this concept. It has been proved that if S is a commutative ternary hypersemiring with hyperidentity, then S is a regular commutative ternary hypersemiring with hyperidentity.

IntroductionIn the course of immune development, HIV-exposed uninfected (HEU) infants exhibit abnormal immune function and increased infectious morbidity compared to HIV-unexposed uninfected (HUU) infants. Yet the specific functional phenotypes and regulatory mechanisms associated with in-utero HIV and/or ART exposure remain largely obscure.MethodsWe utilized flow cytometry and RNA-seq technologies to conduct the immunological and transcriptomic profiling in cord blood from 9 HEU mother-infant pairs and 24 HUU pairs. On top of that, we compared the cord blood dataset with the maternal venous blood dataset to characterize unique effects induced by in-utero HIV and/or ART exposure.ResultsFlow cytometry immunophenotyping revealed that the level of B lymphocyte subsets was significantly decreased in HEU cord blood as compared to HUU (P &lt; 0.001). Expression profiling-based cell abundance assessment, includes CIBERSORT and ssGSEA algorithm, showed a significantly reduced abundance of naive B cells in HEU cord blood (both P &lt; 0.05), supporting the altered composition of B lymphocyte subsets in HEU. Functional enrichment analysis demonstrated suppressed innate immune responses and impaired immune regulatory function of B cells in HEU cord blood. Furthermore, through differential expression analysis, co-expression network analysis using WGCNA, and feature selection analysis using LASSO, we identified a 4-gene signature associated with HEU status. This signature effectively assesses B cell levels in cord blood, enabling discrimination between HEU and HUU infants.DiscussionOur study provides the first comprehensive immunological and transcriptomic characterization of HEU cord blood. Additionally, we establish a 4-gene-based classifier that holds potential for predict immunological abnormalities in HEU infants.
Mixed thyrotropin-secreting pituitary neuroendocrine tumor coexisting with Graves' disease: a case report
Authors: Huang Yijing , Wen Xiaoming , Liang Xinxin , Xu Lingling 
Published: September 2024

BackgroundThyrotropin (TSH)-secreting pituitary neuroendocrine tumors (PitNETs) are recognized as a rare disease. Mixed TSH PitNETs account for 20–25% of TSH PitNETs. This study aimed to report an extremely rare case of a mixed TSH PitNET coexisting with Graves' disease (GD) and also to review the literature.Case presentationA 36-year-old male patient presented with elevated levels of free triiodothyronine (FT3), free thyroxine (FT4), and insulin-like growth factor 1 (IGF-1) but a non-suppressed thyroid-stimulating hormone (TSH) level. His anti-thyroglobulin antibody (TgAb), anti-thyroid peroxidase autoantibody (TPOAb), and thyrotropin receptor antibody (TRAb) tests were positive. Symptoms of palpitations, hyperhidrosis, heat intolerance, and irritability appeared 2 years before his admission. However, he showed neither any signs nor any symptoms of acromegaly. The contrast-enhanced pituitary magnetic resonance imaging (MRI) showed enlargement of the pituitary fossa, with an irregular abnormal signal mass. The patient underwent endoscopic pituitary tumor resection via a transsphenoidal approach. The postoperative pathology suggested a mixed pituitary adenoma. At 8 months after the surgery, the patient had a postoperative recurrence of hyperthyroidism, and methimazole (MMI) was then administered. The recurrence of the TSH PitNET was confirmed by the positron emission tomography-computed tomography (PET-CT), which was performed 11 months after the surgery, and treatment with lanreotide was initiated. Gradually, his levels of FT3, FT4, TSH, TPOAb, and TgAb became normal and the levels of TRAb and IGF-1 improved.ConclusionWhen the circulating levels of both FT4 and FT3 were upregulated, non-suppressed TSH levels and positive thyroid antibodies were found. TSH PitNETs coexisting with GD should be carefully taken into account to avoid the potential risk of treatment-induced tumor progression.

The analysis included scientific research, countries, organizations, authors/cited authors, keywords, journals, and cited references. Bibliometric data were analyzed using VOSviewer software, CiteSpace, GraphPad Prism, and Scimago Graphica. The studies on acupuncture for Parkinson’s disease were visualized as a network map according to the publication year.ResultsThe cumulative publication trend on acupuncture for Parkinson’s disease is increasing year by year. China is the leading contributor in this field. International collaboration is predominantly concentrated in Europe, while institutional collaboration is chiefly limited to Chinese universities specializing in traditional Chinese medicine. Park HJ is the most prolific author, with “Movement Disorders” being the journal with the most publications. “Brain Research” is identified as a key journal, reflecting a focus on neuroscience. Kim SN is the most cited author, while Eisenberg DM is a prominent author in this field. Research topics such as mouse models, systematic reviews, and non-motor symptoms are frequently explored, with messenger RNA of substantia nigra emerging as a notable keyword in this field. Choi YG’s 2009 paper, published in the Neuroscience Letters journal, is a critical reference in this field. Key papers include Eisenberg DM’s 1998 study on randomized trials of acupuncture for non-motor symptoms of PD, as well as research focusing on the neuroinflammatory regulatory mechanisms of acupuncture for PD.ConclusionThe bibliometric analysis offers an exhaustive generality of the advancement and worldwide trends in acupuncture treatments for Parkinson’s disease, shedding light on potential avenues for prospective research.

IntroductionHispanic/Latino populations are underrepresented in Alzheimer Disease (AD) genetic studies. Puerto Ricans (PR), a three-way admixed (European, African, and Amerindian) population is the second-largest Hispanic group in the continental US. We aimed to conduct a genome-wide association study (GWAS) and comprehensive analyses to identify novel AD susceptibility loci and characterize known AD genetic risk loci in the PR population.Materials and methodsOur study included Whole Genome Sequencing (WGS) and phenotype data from 648 PR individuals (345 AD, 303 cognitively unimpaired). We used a generalized linear-mixed model adjusting for sex, age, population substructure, and genetic relationship matrix. To infer local ancestry, we merged the dataset with the HGDP/1000G reference panel. Subsequently, we conducted univariate admixture mapping (AM) analysis.ResultsWe identified suggestive signals within the SLC38A1 and SCN8A genes on chromosome 12q13. This region overlaps with an area of linkage of AD in previous studies (12q13) in independent data sets further supporting. Univariate African AM analysis identified one suggestive ancestral block (p = 7.2×10−6) located in the same region. The ancestry-aware approach showed that this region has both European and African ancestral backgrounds and both contributing to the risk in this region. We also replicated 11 different known AD loci -including APOE- identified in mostly European studies, which is likely due to the high European background of the PR population.ConclusionPR GWAS and AM analysis identified a suggestive AD risk locus on chromosome 12, which includes the SLC38A1 and SCN8A genes. Our findings demonstrate the importance of designing GWAS and ancestry-aware approaches and including underrepresented populations in genetic studies of AD.

IntroductionTo identify predictors of excessive daytime sleepiness we analyzed data from the ‘Epidemiology of cardiovascular diseases in regions of Russia (ESSE-RF)’ study.MethodsData from participants of the cohort study ESSE-RF (2012–2013), aged 25–64 years, from 13 regions of Russia were analyzed (2012–2013). The participants were interviewed regarding their sleep complaints, including difficulties with initiating and maintaining sleep, sleepiness, and use of sleeping pills. Sleepiness was considered significant if it occurred at least three times a week. The examination encompassed social, demographic, and anthropometric measures, lifestyle factors, self-reported diseases, and laboratory parameters. The final analysis included 13,255 respondents.ResultsFrequent (≥3 times/week) sleepiness was reported by 5,8%, and occasional sleepiness (1–2 times/week) by 10.8% of respondents. Multivariate regression analysis identified significant predictors of frequent sleepiness. Sleep complaints (insomnia, sleep apnea, snoring) and frequent use of sleep medication were prominent factors. Additionally, age, female gender, higher education, and retirement status were associated with sleepiness. Beyond demographics and sleep, the analysis revealed predictors: abnormal anxiety levels, low high-density lipoprotein, high salt intake and following medical conditions: arrhythmia, hypertension, myocardial infarction, other heart diseases, and renal disease.ConclusionThis study identified a significant prevalence of EDS in Russians, aligning with global trends. However, findings suggest potential regional variations. Analysis revealed a complex interplay of factors contributing to EDS, highlighting the importance of individualized treatment approaches for improved sleep health.
