The present invention provides compounds of Formula :or a stereoisomer, tautomer, pharmaceutically acceptable salt or solvate form thereof, wherein the variables A, B, R3 and R11 are as defined herein. To validate the feature key, the ultrasound imaging system decrypts the encrypted data and then compares the decrypted data to validation data pre-stored in the system. The similarity with respect to the registered object model is determined, and the type of the object to be a recognition target is output, which is determined to be most similar among the registered object models. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract. The mobile receiver receives GPS signals, performs rudimentary signal processing and transmits the processed signals to the wireless carrier. An image processing means administers image processes onto the plurality of mammograms based on predetermined image processing conditions.
