The present invention relates to compositions and methods for providing aphid resistance in plants. In particular, it has been discovered that, by maintaining and selectively propagating taint status for storage locations in correspondence with information flows of instructions executed by a computing system, it is possible to provide a security response if and when a control transfer is attempted based on tainted data. The vehicle ontology records all the substances used in the design of the vehicle along with all the attributes of the substances and the relations between the substances. The method interpolates between the selected example crops to determine a crop window, crops the original image with the determined crop window to produce the cropped image. A fill material is deposited to substantially fill the depression and a portion of the dielectric layer is etched.
