A device mount system is provided that is designed to mount a device used in hunting, such as a video camera, rangefinder, game caller or the like, to a crossbow. One row of radiating elements is shared between two sub-arrays by a coupler which isolatingly couples one row of radiating elements to each of two sub-arrays allowing the feed to the two sub-arrays to be isolatingly applied to the shared row of radiating elements while suppressing grating lobe generation and providing high sub-array isolation. In some embodiments, the invention relates to methods of treating cancer, and in particular breast cancer, by administering a composition comprising an RNA interference sequence characterized by an ability to inhibit an mRNA molecule, which mRNA molecule is encoded by the C43 gene. When software is downloaded or to be executed, the trust in the authorpublisher is determined using digital signatures andor CoAs associated with the software. Embodiments of the invention integrate database connectivity and error detection into the IDE tool, thereby potentially reducing the time required for database-aware application development.
