On the Convergence of ILC for Hilfer Fractional-Order Systems with Initial State Errors
This paper addresses tracking control for nonlinear Hilfer fractional-order systems (HFOS) with initial state errors. To enhance tracking performance over repeated operations, a closed-loop Dα,β-type and first-order PDα,β-type iterative learning control strategy is proposed. By e...

Medical radiation at the crossroads of complexity and opportunity: New staff perceptions
Background New hospital staff represent a critical yet underexplored group in radiation safety research. Their initial perceptions and early experiences with safety systems are formative, shaping long-term professional behaviours and highlighting systemic gaps in onboarding and s...
Impact of Smokeless Tobacco on Semen Quality: A Systematic Review and Meta‐Analysis
ABSTRACT Background Smokeless tobacco products are widely regarded as a safer alternative to smoking. However, a growing body of evidence points to harmful effects on male reproductive health. The aim of this systematic review and meta‐analysis was to assess the association betwe...
