A method of diagnosing metastatic potential of a breast cancer in an individual with breast cancer is described. The method further includes a step of dry etching the semiconductor layer to form a trench with a charge prevented from building up on a surface of the insulating layer that is exposed at a bottom of the trench during the dry etching. The control section controls high discharge without power assist limit to the vehicle in the route before a downhill travel path of the route based on the route information output from the car navigation apparatus. The programming language includes an API to allow an application to make calls using the API to allocate execution of the threads between the host processor and the GPU.
