The present application suggests an electronic device and method for generating clock signals with and without frequency jitter for one source clock signal generated by a single narrow-band source clock signal. A transformation mechanism of the embedded device applies a nonlinear magnification or pinching transformation to the region of interest such that magnification or pinching within the region of interest varies from a greater amount at a focal point of the region of interest to a lesser amount at an outer border of the region of interest. The tubular substrate includes an outer sidewall with a catalyst layer located on the outer sidewall. One or more guidance devices may be sold as part of a kit that includes an identification marker mountable adjacent an entry door of a building, and instructions for coordinating mounting positions of the identification marker and the guidance device relative to their respective doors. For the column-DCT, two columns are preferably processed in parallel using SIMD instructions to improve computational efficiency. Included are nucleic acid constructs useful for inactivating the \u03b1-1,3 galactosyltransferase gene in a target cell.
