Optical activation function using a metamaterial waveguide for an all-optical neural network [PDF]

open access: yesarXiv
In this study, we experimentally demonstrated that the nonlinear optical coefficient of the original Si can be enhanced by incorporating a metamaterial structure into an existing silicon waveguide. The two-photon absorption coefficient enhanced by the metamaterial structure was 424 cm/GW, which is 1.2x10^3 times higher than that of Si.

UDP‐glucose dehydrogenase variants cause dystroglycanopathy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Abstract UDP‐glucose dehydrogenase (UGDH) variants have been associated with hypotonia, developmental delay, and epilepsy. We report the first pathologic evidence of dystroglycanopathy in siblings with UGDH variants. Both presented around 6 months with developmental delay and elevated creatinine kinase.
