A non-volatile memory transistor with a nanocrystal-containing floating gate formed by nanowires is disclosed. Failure to detect LRAT expression indicates presence of cancer, and detection of lower than normal level of LRAT expression indicates a precancerous condition. A client receiving the MPEG transport stream, including the embedded customized control packets, will, on the basis of the package identification data obtained from a customized control packet be able to identify each of n packets which were inserted by the server into the transport stream subsequent to the respective customized control packet. Usefully, header free packets comprise one of the packet types. The probe provides an electrical measurement of the reference sample feature based on an e-beam induced current. Trenches are etched into the porous low-k dielectric layer using the organic planarization layer as a mask.
