A system and method for single hop, processor-to-processor communication in a multiprocessing system over a plurality of crossbars are disclosed. The BVM having the usual patient mask with a gas inlet and flexible patient face sealing edge, flexible manually squeezed bag with a one way intake and output valves in flow communication with a gas source and the mask inlet, and exhaust port for exhausting exhaled gas from the mask when the bag output valve is closed. Particle beam simulation may be used to calculate the pattern and the edge slope. In the second mode, current flows from the second current electrode to the first electrode of the first non-volatile memory cell and charge is transferred from the current to the floating gate of the first non-volatile memory cell at a location nearer the second current electrode than the first current electrode. The second program includes program code implementing the QR decomposition and the auxiliary function for the first function in the first program. An annular support cuff is connected to the spike which seals off a portion of the cavity of the body such that an upper cavity containing the tip is defined.
