An improved damascene method of forming a write coil of a magnetic head. The plasma display apparatus includes a plasma display panel comprising a first electrode and a second electrode, and a driver for applying a plurality of sustain signals to the second electrode while applying two consecutive sustain signals to the first electrode in a sustain period. The analysis routine is defined by at least one abstract rule set having one or more abstract rules each having a conditional statement and a consequential statement. In the third configuration, the walls are stacked relative to the base. Other embodiments are also disclosed. In addition, the present invention provides methods of delivering a nucleic acid to a cell using the AAV4 vectors and particles.
