A system, apparatus, and method are disclosed for a resonant scanner for three-dimensional mapping. The temperature sensor and the electronic cooling device control a temperature of the optoelectronic transducer. The electrode may be implanted within the left ventricle by feeding the electrode from the right ventricle through the right ventricular septum and into the left ventricle. The first optical zone, in combination with the second optical zone, provides a power profile in which the optical power of the lens decreases outwardly from the optical axis to the outer periphery such that the optical power at a 6 mm diameter is from about 1 to 5 diopters smaller than a manifest refractive power for an eye. Also provided are pharmaceutical compositions comprising a MTP inhibitor and a L-FABP inhibitor. Tape library commands implemented in response to commands received from a data protection application are emulated in a disk based storage medium so that existing data protection applications may be used to copy data to and from the disk based storage medium.
