Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Variants in SLC6A1, encoding the GABA transporter 1 (GAT‐1), cause epilepsy, autism spectrum disorder, and developmental delay via loss of GABA uptake, impaired trafficking, and ER retention. We previously found that 4‐Phenylbutyrate (PBA), an FDA‐approved drug, restores GABA uptake and reduces seizures in SLC6A1‐related disorders ...

A Hybrid Dual-Mode Control for Permanent-Magnet Synchronous Motor Drives
IEEE Access, 2020 In order to obtain satisfactory transient and steady-state performances, a hybrid dual-mode control (HDMC) is proposed for surface-mounted permanent-magnet synchronous motor drives (PMSMs), which contains two control modes.
