A mounting unit for mounting a solar panel on a roof includes a base having a first flange and a second flange that extend laterally from the base and a mounting surface positioned above the base via walls that connect the mounting surface and the base. A dynamic interface is implemented, which includes a plurality of interface modules that permits varying data-processing applications to scan, identify and interface with the plurality of components utilizing the inputoutput interface, thereby increasing data-processing application development efficiency relative to one or more components within the data-processing system. The synchronous series resonant inverter includes a primary winding having across its terminals a periodic voltage V of period T, this primary winding being coupled to at least one secondary winding providing the output voltage Vs. The invention thus makes possible therapeutic strategies that optimally target metastatic cells while preventing collateral damage to normal tissues. In one embodiment, the elliptically cylindrical ionizing region includes a pair of co-focal elliptically cylindrical electrodes biased so as to cause electrons emitted from the at least one electron source to orbit repeatedly through the axis of the beam to be ionized.
