Extracellular Vesicles as Molecular Regulators of Viral Infection: Implications for COVID-19 and Future Viral Pandemics

Coronavirus disease 2019 (COVID-19), caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), exposed critical gaps in global preparedness for rapidly evolving viral pandemics. Though current antiviral treatments have shown some efficacy in managing COVID-19, subst...

Trust, Information Appraisal, and Health Communication Behaviours Among People Living with Multiple Sclerosis

Background: People living with multiple sclerosis (MS) are increasingly turning to the Internet for information about their condition and its treatment. However, online health information varies widely in quality, and patients often lack the eHealth literacy needed to distinguish...

Interpretable neural network forecasting of CO₂ emissions from renewable and non-renewable energy use in Saudi Arabia

Energy-intensive economies need to precisely forecast CO₂ emissions associated with energy use to be well-prepared for sustainability. This study aims to develop a precise predictive framework for modeling Saudi Arabia’s CO 2 emissions using artificial neural networks (ANNs). A c...

Framing regional identity through conceptual metaphor: A cognitive linguistic analysis of Arabic tourism discourse in Ha'il, Saudi Arabia

This article examines how Arabic institutional tourism discourse constructs the regional identity of Ha'il, Saudi Arabia, through scenario-based conceptual metaphors situated within the Vision 2030 tourism policy horizon. Drawing on Conceptual Metaphor Theory, image-schema analys...

A Dimensionless Similarity Framework for Organic Rankine Cycles: Generalized Performance Maps and Reduced-Pressure Optimality

Organic Rankine Cycles (ORCs) have become one of the most promising technologies for converting low- and medium-grade waste heat into useful power. However, conventional ORC analyses are typically performed using dimensional variables and application-specific operating conditions...

Global Dynamics and Complete Phase Portrait Classification of a Nonlinear SIRS Model with Saturated Incidence

This paper investigates the global dynamics of a nonlinear Susceptible–Infective–Recovered–Susceptible (SIRS) epidemic model with a nonmonotonic saturated incidence rate. By reducing the model to a planar cubic polynomial differential system, we perform a complete qualitative ana...

Divorce trends in Hail, Saudi Arabia, and their socio-cultural drivers (2010–2020)

Divorce has emerged as a significant and ever-increasing social challenge in contemporary Saudi Arabia, particularly among newly married couples. This study examines the socio-cultural and structural factors associated with rising divorce rates in the Hail region, which ranks amo...

Cigarette smoking history, e-cigarette use, and Long COVID: a population-based analysis

Abstract Long COVID imposes a substantial public health burden following the SARS-CoV-2 pandemic, yet the contribution of electronic cigarette (e-cigarette) use, alone or alongside cigarette smoking, remains inadequately characterized in population-representative data. We conduct...

Eugenol extraction and characterization from clove as a potential anticancer therapeutic agent against breast cancer: Combining an in vitro and in silico molecular docking and dynamics studies

Breast cancer (BC) is leading cause of cancer-related mortality among women worldwide, with approximately 2.3 million new cases and 670,000 deaths reported in 2022. Despite advances in therapy, challenges such as drug resistance and adverse side effects necessitate the exploratio...

From organizing center to threshold configuration: a morphogenetic reading of Aleppo’s long-term urban transformation

Purpose This article examines Aleppo as a long-term urban transformation process and asks how organizing centers, mobility/access structures and socio-spatial differentiation shaped its urban form across successive historical phases. Here, morphogenesis is understood as the histo...

Exploring memory effects and chaotic transitions in the fractional–order Bogoyavlenskii dynamical system

We explore the fractional form of the Bogoyavlenskii equation in this work using the modified version of the Riemann-Liouville fractional derivative operator introduced by Jumarie to reveal the memory and hereditary properties of the fractional dynamical systems. This analytical...

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...

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...

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...

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...

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...

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...
