An article with an improved buffer layer architecture includes a substrate having a textured metal surface, and an electrically conductive lanthanum metal oxide epitaxial buffer layer on the surface of the substrate. The frequencies fc1 and fc4 satisfy the inequalities \xb7fc4\u2266n\xb7fc2 and n\xb7fc3\u2266\xb7fc1 andor satisfy an approximate expression n\xb7fc4\u2248\xb7fc1 where n is an integer. The input is provided as instructions, which are described according to a reference coordinate system, to a movement system for moving the object within a scene. 850; a gradient of the crystallinity against a thickness of the pipe is 0. Basically, by utilizing a resource manager, that directs the data in and out of the various portions of the modem in an orderly manner, keeping track of which of the ports is being operated at any given point in time, a standard single port modem can be reconfigured, for example, at an over clocked rate, to manipulate the data input and output of a modem.
