Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

Advanced Engineering Materials, EarlyView.Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

The origin of the equation for the interfacial coefficient of heat transfer
Communications, Faculty Of Science, University of Ankara Series B Chemistry and Chemical Engineering, 1988 Among the few assumptions that Nusselt made in deriving his widely used equation for the condensate film heat transfer coefficient was the one which stated that the condensate film offers the only resistance to the heat transfer. Thİs means that the effect of the vapour pbase on the heat.
