Our single-celled ancestor lived in a world without plants, animals or oxygen-rich oceans. Yet, this seemingly simple microorganism took the first steps toward complex life. From this ancestor emerged ...

Abstract: The superposition of aging characteristics in fuel cells is a major cause of inaccurate predictions. Unlike traditional methods that mix linear and nonlinear aging characteristics, this ...

Abstract: A simple waveguide-Floquet mapping is proposed and theoretically investigated that links the scattering response of a sub-wavelength metasurface unit cell under an infinite periodic array ...
