A clock divider and method of operating the same. In embodiments, the modified proppant comprises a proppant particle and a hydrogel coating, wherein the hydrogel coating is applied to a surface of the proppant particle and localizes on the surface to produce the modified proppant. The filler neck further comprises a blocking element that is arranged inside the filler pipe and extends only inside a circle sector of a circle concentric to the circular cross section. The male member defines ridges and grooves and the collar defines corrugations, each preferably in the form of modified buttress threads, which yield, fracture, or strip when the compressible support is subjected to additional force, decreasing the overall length of the compressible support. The first electrode is connected to a magnetic reference layer at the bottom, and the second electrode is located at the middle memory layer which is connected to the underneath CMOS circuit through VIA and the third electrode is a voltage gate connecting to the top bit line which is used to reduce the write current when a voltage is applied between the top and middle electrode. In one possible embodiment, a motor winding is provided that has a high density multi-conductor wire bundle comprises of compacted Litz wire.
