An embodiment includes disposing optically visible marks along one or more spiral segments on a rotating medium, where the one or more spiral segments include a plurality of seams, and locating the seams at different angular locations on the rotating medium. The shape detection apparatus detects positions of respective points in an insertion section of the endoscope, estimates the shape of the insertion section on the basis of the detected positions, and displays an image representing the modeled shape of the insertion section corresponding to the estimated shape. Tubular insulators abut the bore-confronting inner surface of the winding end portions, whereby the tubular insulators bound respective cavities in concert with end faces of the stator housing and the cooling jacket for receiving the winding end portions, with the cavities being filled with insulating casting material. The decoder includes a number of Context Reconfigurable Instruction Set Processors. The blocks of data are also analyzed to determine whether certain relationships among the groups of bits of data exist within the blocks of data. Specifically disclosed is an AR IgG1 Fc fusion protein, comprising the androgen binding domain of human androgen receptor and the Fc region of IgG.
