Methods for fabricating a back-end-of-line wiring structure, BEOL wiring structures, and design structures for a BEOL wiring structure. Transmitting the detecting signals to a service end. Blocked stacked arrangements and slanted stacked arrangements are shown. And, hence, the present invention is suitable for mass producing reliable power-diode drivers. In certain examples, electromagnetic energy, such as microwave energy, may be used in the treatment process to reduce the amount of or eliminate the pathogen from the keratinized tissue. The coupling includes a first opening for receiving the first piece of electrical conduit, a second opening for receiving the second piece of electrical conduit, and a body extending between the first and second openings.
