Methods and an apparatus for enhancement of source coding systems utilizing high frequency reconstruction are introduced. A coated receptor film having a coating layer and a support layer is imaged using an ink-jet printer or plotter in areas corresponding to the open stencil areas. The inductor structure can include a patterned ground shield including a plurality of fingers implemented within an IC process layer located between the coil of conductive material and a substrate of the IC. The IB viruses of the invention are useful for, inter alia, vaccines against IB-QX and IB-QX-like viruses.
