A non-curable coating composition which uses a modified silicone having a functional group and can effectively prevent or reduce adhesion of sticky contamination substances to the surface of a substrate is provided. The method also includes applying a correction table to the measured OSNR to generate a corrected OSNR using a controller, the correction table comprising a correction function to counteract an artifact in the measured OSNR. Instructions, excepting and non-excepting, can be reordered by the control speculation module if the instructions meet certain conditions. The at least one opening may expose at least one interior surface on the core. The first and second stacks each function optically in series on at least a portion of their surface and are separated by an electrically insulating mechanism.
