Research ArticleOpen accessIn the keywordsMODEL SELECTION VIA ROBUST VERSION OF R-SQUAREDShokrya SalehR-squared (R2) is a popular method for variable selection in linear regression models. R2 based on Least Squares (LS) regression minimizes the sum of the squared residuals; LS is sensitive to outlier observation. Alternative criterion based on M-estimators, which is less sensitive to outlying observation has been proposed. In this study explicit expression for such criterion is obtained when the … …Journal of Mathematics and Statistics, Vol. 10, Issue 3 · 9 Oct 2014 · 7,460 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Simple Robust Control Chart Based on MADMoustafa Omar Ahmed Abu-ShawieshControl charts are one of the most powerful tools used to detect aberrant behavior in industrial processes. The Shewhart S-control chart is one of the most widely used statistical process control techniques developed to control the process variability based on the fundamental assumption that the underlying distribution of the quality characteristic is normal. When the underlying normality assumption is not … …Journal of Mathematics and Statistics, Vol. 4, Issue 2 · 30 Jun 2008 · 14,254 accessesView PDFCite
Research ArticleOpen accessIn the abstractExploring the Relationship Between Skin Barrier Function, Sensitivity, and Repair MechanismsXiaoqing Yan, Yusong Shi, Jiguang YangFor healthy skin, the skin's barrier function must remain maintained. Many different molecular while immunological signaling mechanisms are involved in skin barrier control. The control of a healthy skin barrier, particularly acid mantle maintenance and proper amounts of ceramides, may help dermatologists develop remedies for skin barrier disruption disorders. In contrast, new medicines could focus on signaling pathways to offer … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 15 Feb 2026 · 1,893 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Chain Mediating Role of Technology Self-Efficacy and Attitudes in Online Learning EnvironmentsJie Gao, Dolores D. Borras, Beverly T. CaigaThis study investigates the mediating role of technology self-efficacy and attitudes in online learning environments among university students. Specifically, we examined how students' technology self-efficacy, attitudes toward online learning, and perceptions of course appropriateness influence online learning outcomes. Data were collected via questionnaire survey from students enrolled in public and private universities (N = [specify number]). Structural equation modeling with … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 16 Feb 2026 · 1,601 accessesView PDFCite
Research ArticleOpen accessIn the abstractUltrastructural and Circadian Morphometric Characteristics of Rat Pinealocytes Under Physiological and Toxic ConditionsAnna I. Anurkina, David A. Areshidze, Maria A. Kozlova, Valery P. ChernikovCarbon tetrachloride (CCl₄) exhibits pronounced neurotoxic effects following acute or chronic exposure. Recent studies indicate that the pineal gland responds to CCl₄ intoxication by altering its secretory function, although detailed ultrastructural changes in pinealocytes remain inadequately investigated. This research addresses the urgent need to elucidate the mechanisms of CCl₄ toxicity on the pineal gland, which could contribute to developing strategies … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 1 Jun 2026 · 1,170 accessesView PDFCite
Literature ReviewOpen accessIn the abstractPotential Therapies for Mitochondrial Diseases Caused by mtDNA MutationsAnastasia V. Poznyak, Nikolay A. Orekhov, Dmitry Felixovich Beloyartsev et al.Mitochondrial diseases, caused by mutations in mitochondrial DNA (mtDNA), present significant genetic and clinical complexities that challenge accurate diagnosis and treatment. This review examines the critical molecular mechanisms underlying these disorders, particularly the role of heteroplasmy, where mixtures of mutated and normal mtDNA influence disease severity, and the nuclear-mitochondrial DNA interactions that compound diagnostic and therapeutic challenges. The threshold effect, … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 15 Feb 2026 · 1,735 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of the Influence of Dust-Salt Aerosols of the Aral Sea on the Morphological Characteristics of the Tissue of the Epididymis of Rats in the ExperimentAssylgul Suleimen, Bibigul Rakhimova et al.Drying of the Aral Sea is a very significant environmental problem of modern times. Dust particles from the dried seabed are spread over long distances and negatively impact the quality of life of residents in nearby areas. One of the significant problems is the decrease in the fertility of residents of the Aral region, but there is insufficient data about … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 24 Jul 2024 · 4,809 accessesView PDFCite

Literature ReviewOpen accessIn the abstractRumen Microbiota Mysteries: Nutrition, Function, and its Impact on Livestock ProductivityHamdi Mayulu, Marry ChristiyantoRuminants are important herbivores in the global food system, serving as primary producers of meat and milk. The productivity of these animals is influenced by the functionality of their digestive organs, namely rumen. The digestion, metabolism and nutrients absorption in the rumen epithelium enhance the host defende mechanisms mechanisms, promoting health and productivity in ruminants. Therefore, this review aimed to … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 2 · 4 Aug 2025 · 4,069 accessesView PDFCite
