In a magnetron having a body 1 defining an anode 2 divided into resonant cavities 4 by vanes 3 and having a coaxial cathode 5, r. This program includes at least nine steps, especially estimates impedances at zero frequency from respective impedances in positive and negative frequency regions, and reflects the result on the transient response analysis. Also provided for are methods for the diagnosis, treatment, or prevention of diseases with IL-17 like polypeptides or antagonists thereof. A position where the search range S is set is corrected based on the amount of the deviation of an infinite distance corresponding point with respect to a position of the reference image data. As such, distributed route reoptimization is triggered in the communication network at the adaptively determined frequency. Also provided is a customized ophthalmic element including an ophthalmic substrate; and a variable-index layer of a liquid crystal material connected to at least a portion of the substrate.
