An interleaved high step‐up DC–DC converter based on coupled‐inductor

IET Power Electronics
This paper proposes an interleaved coupled‐inductor high step‐up direct current (DC)–DC converter. This converter uses a coupled inductor (CI), a voltage multiplier (VM) integrated with a regenerative passive lossless clamp circuit to enhance the voltage

Fluid Biomarkers of Disease Burden and Cognitive Dysfunction in Progressive Supranuclear Palsy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Identifying objective biomarkers for progressive supranuclear palsy (PSP) is crucial to improving diagnosis and establishing clinical trial and treatment endpoints. This study evaluated fluid biomarkers in PSP versus controls and their associations with regional 18F‐PI‐2620 tau‐PET, clinical, and cognitive outcomes.
