On the Structure of Laminar Diffusion Flames. [PDF]

open access: yes, 1963
The structure of laminar diffusion flames is analyzed in the limiting case of large, although finite, reaction rates. It is shown that the the chemical reaction takes place only in a very thin region or "chemical boundary layer" where convection effects may be neglected. Then the temperature and mass fraction distributions within the reaction zone are

Epilepsy‐Associated Variants of a Single SCN1A Codon Exhibit Divergent Functional Properties

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Pathogenic variants in SCN1A, which encodes the voltage‐gated sodium channel NaV1.1, are associated with multiple epilepsy syndromes exhibiting a range of clinical severity. SCN1A variants are reported in different syndromes, including Dravet syndrome, which is associated with loss‐of‐function, whereas neonatal/infantile‐onset ...
