The rapid integration of generative artificial intelligence (AI) tools such as ChatGPT into higher education has raised important questions about how students evaluate the ethical implications of AI-assisted academic practices and whether those evaluations are linked to intention...

Spectral Chebyshev wavelet method for state-dependent fractional integro-differential equations in adaptive tumor growth modeling

This paper develops a Chebyshev Wavelet Operational Matrix Method (CWOMM) for solving a novel class of nonlinear mixed Volterra–Fredholm fractional integro-differential equations with state-dependent kernels and time-varying coefficients. Unlike classical formulations, in which t...

Hemodialysis access creation in a resource-limited conflict zone: outcomes of a localized surgical training initiative

Abstract Background Reliable vascular access is essential for patients with end-stage kidney disease. In conflict-affected Yemen, limited access to vascular surgical expertise poses challenges to hemodialysis access care. A WHO-supported vascular trauma training program in Al-Hod...

Comparative antioxidant recovery evaluation of ultrasound and supercritical CO₂ Yemeni red onion peel extractions with LC-ESI-MS/MS profiling of ultrasound-assisted extracts

Yemeni red onion ( Allium cepa L.) peels of the local Yemeni cultivar ‘Ba Fatim’ represent an underutilized agro-waste rich in bioactive compounds with significant antioxidant potential. This study aimed to comparatively evaluate ultrasonic-assisted extraction (UAE) and supercrit...

Correlation of maxillary anterior tooth width with facial dimensions in a Yemeni subpopulation: a cross-sectional study

In restorative and prosthetic dentistry, an aesthetic smile is strongly dependent on the harmonious interaction between maxillary anterior teeth and facial proportions. Although similar associations have been studied in various populations, data from Yemeni adults remain limited....
