A method of and system for providing machine-readable tags, preferably programmable RFID tags are provided. The cycle slip detector includes a cycle slip detection filter possessing a predetermined filter bandwidth and a predetermined high frequency cut-off. The Schottky diode further includes a bottom-doped region of the second conductivity type surrounding a bottom surface of the trench and a top-doped region of the second conductivity type surrounding a top portion of the sidewalls of the trench. A plurality of barbs within the collar are activated to pierce and engage an inner surface of the riser pipe. Further, the present invention relates to a method for diagnosing breast cancer, comprising the step of detecting the cytokeratin 818 complex-specific autoantibody or the fragment comprising the antigen-binding site thereof using the composition of the present invention, and a method for screening a therapeutic agent for breast cancer using the autoantibody.
