Abstract: Disclosed herein are cells and cell lines that are selected for retention of at least two exogenous nucleic acid constructs using a single selective pressure. Also disclosed herein are compositions and methods for generating recombinant cells and cell lines using a single selective pressure.

Abstract: A power-combining system and method for generating a high-power coherent wavefront are generally described herein. Other embodiments may be described and claimed. The power-combining system comprises a combining-radiating assembly having a plurality of ports. Phase controllers generate signals with a predetermined phase shift for an associated one of the ports. Pluralities of coherent sources receive signals from an associated one of the phase controllers and to provide the signals to an associated port of the combining-radiating assembly with the predetermined phase shifts. Energy from the ports is coherently combined and radiated to provide a coherent high-power wavefront. In some embodiments, the combining-radiating assembly comprises a conductive patch having a plurality of ports spaced uniformly around the patch. In these embodiments, energy from the ports is coherently combined and radiated by the patch to provide the coherent high-power wavefront.
