Computer methods, systems, and devices, providing automatic permutations of a programmed modified random symbol square matrix producing one time pad messages are disclosed enabling messages to be encrypted from plain text which is typed into a computer thereby selecting random symbols from the matrix. More specifically, the invention concerns the use of inhibitors of the phosphatase PTEN, such as oxovanadate and peroxovanadate complexes, in methods for in vitro and in vivo maturation of follicles and oocytes. The mounting system also includes a controller that controls an electronic component mounting operation on the basis of a result of identification obtained by the component identifying apparatus.
