A process may include first etching a trench isolation dielectric through a dielectric hard mask that abuts the sidewall of a fin semiconductor. The HOE receives the input wavefront and includes a hologram of a particular wavefront recorded with reference waves, each defining a particular aberration coefficient. Because the antibodies or antibody fragments act only at the sites of thrombus formation and do not interfere with the normal activity of circulating platelets, they are particularly well suited for use as antithrombotic agents in a wide variety of applications. Each inductor generates a magnetic flux that has a discernible axis. The sliding door system is lightweight and robust, and enables sliding doors to be displaced freely without a particular sliding door being assigned in a fixed manner to a particular opening to be covered. When current is passed from the first electrode to the second electrode through the phase-change material, at least one of the first and second electrodes remains unreactive with the phase change material.
