An optical control electromagnetic wave circuit comprises a unit composed of a semiconductor layer, a transparent substrate, and a transparent grounded conductive layer and a displaying unit. An alternative to applied profiles is disclosed. When folded, tops of the first and second frame sections face each other, with the at least one rear wheel between sides defined by the shield elements. The human STEAPs exhibit a high degree of structural conservation among them but show no significant structural homology to any known human proteins.
