More human research is still needed to confirm the benefits and safety of most nootropic supplements. None are FDA-approved for brain function. Fish oil, ginkgo biloba, and creatine are three ...

This paper introduces a hybrid maximum power point tracking (MPPT) technique for photovoltaic (PV) arrays working under partial shading conditions. This new algorithm can combine a traditional MPPT ...

This work seeks novel designs of S-band high power microwave antennas based on rectangular waveguide narrow-wall longitudinal-aperture array structure. A narrow-wall slot-array is proposed to achieve ...
