Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Considerable efforts have been dedicated to developing effective treatments for post‐stroke executive impairment (PSEI), among which repetitive transcranial magnetic stimulation (rTMS) has shown great potential. This study aimed to investigate the therapeutic effects of high‐frequency rTMS on working memory (WM) and response ...

Arthritis Care &Research, EarlyView.Objective Hydroxychloroquine (HCQ) is a cornerstone therapy in systemic lupus erythematosus (SLE), but the weight‐based dosing does not account for clinical factors that can introduce individual variability in drug metabolism and clearance. We leveraged longitudinal data from a prospective SLE cohort to identify clinical factors that predict ...

High-speed digital-to-analogue convertor using passive switched-capacitor algorithmic conversion
Electronics Letters, 1988 A purely passive parasitic-compensated switched-capacitor circuit is shown to implement a simple signal conversion algorithm consisting of a mere charge division between equal valued capacitors. Such a circuit is the core of the new digital-to-analogue convertor described in this letter, and which is particularly suitable for high-frequency ...
