Polynomial Stability of the Timoshenko Beam System with a Fractional Dynamic Boundary Feedback

We investigate the asymptotic behavior of a Timoshenko beam system in which the free end carries a tip mass subject to a restoring spring force and a tempered Caputo fractional damping force with parameter η>0 (the case η=0 is left as an open problem). Using a diffusive state...

AI adoption intensity and sustainability performance through organizational change and environmental dynamism in Saudi Arabia manufacturing companies

As economies and societies continue to develop rapidly, businesses are now placing greater emphasis not only on financial performance but also on environmental and social performance. Therefore, there is increasing attention to how businesses can use artificial intelligence as a...

Efficacy and safety of BAFF/APRIL-pathway inhibitors versus placebo in adults with IgA nephropathy: a systematic review with pairwise and network meta-analysis

B-cell activating factor (BAFF) and a proliferation-inducing ligand (APRIL) drive the galactose-deficient IgA1 (Gd-IgA1) production that underlies IgA nephropathy (IgAN). Several BAFF/APRIL-pathway inhibitors have entered randomized testing, but none has been compared head-to-hea...

Antibiotic susceptibility of genital tract isolates in pregnant women with premature pre-labour rupture of membranes (PPROM) in a low-resource setting

Premature pre - labour rupture of membranes (PPROM) is a significant obstetric complication that contributes to preterm births, maternal infections, and neonatal morbidity. The role of genital tract infections in the etiology of PPROM is well established, yet data on microbial is...

A feature-centric predictive and sensitivity analysis framework for bio-oil yield assessment in biomass pyrolysis

Abstract Accurately predicting bio-oil yield from biomass pyrolysis is a real challenge due to nonlinear interactions between feedstock physicochemical properties and operating conditions. In addition, high feature dimensionality, uncertainties in experimental measurements, and m...

Human-centered AI in E-commerce: Examining consumer engagement through attitude and perceived value

Background The integration of artificial intelligence (AI) into E-commerce platforms is reshaping digital consumer experiences. However, empirical evidence examining the mechanisms through which AI-related perceptions translate into consumer engagement in emerging digital economi...

Reciprocal Mean Square Index of Graphs

The reciprocal mean square (RMS) index of a graph G with edge set E(G) is defined by RMS(G)=∑uv∈E(G)[(d(u))2+(d(v))2]−1, where d(u) and d(v) are the degrees of vertices u and v, respectively. We first establish several bounds for the RMS index in terms of standard graph parameter...

Spatially-integrated Ancestry Polygenic Risk Mapping for Diabetes: A Geographic-adjusted Genetic Scoring Framework

Abstract Background: Conventional polygenic risk scores (PRSs) often fail to capture geographic and ancestry-specific variation, limiting their predictive accuracy in admixed and globally diverse populations. This study aims to develop a spatially-aware PRS (SA-PRS) framework tha...

Digital Learning Tools in Language Education: An Explanatory Model of Their Effects on Language Skills and Quality of Life

This study examines the extent to which Arabic language teachers employ digital learning tools and proposes an explanatory model of their effects on language skills development and students’ quality of life. An explanatory approach was adopted, and data were collected through a q...

2D-unsteady chaotic flows for mixing two different non-Newtonian fluids: optimization and flow control

Mixing of non-Newtonian fluids has been widely studied, yet numerical investigations of the simultaneous mixing of two different shear-thinning fluids inside chaotic mixers remain limited. In this work, we numerically investigate, for the first time, the mixing of two shear-thinn...

Resolution of severe autoimmune hemolytic anemia and thrombocytopenia associated with Plasmodium vivax malaria without corticosteroid therapy: A case report

Rationale: Autoimmune hemolytic anemia is a rare but potentially life-threatening complication of Plasmodium vivax malaria. Most reported cases required corticosteroid therapy in addition to antimalarial treatment. Patient concerns: We report the case of a 28-year-old Ethiopian m...
