A shielded magnetic head includes a magnetically shielded gap and first to fourth conductive magnetic films disposed in the gap. The battery includes a solid oxide electrochemical cell integrated with a redox couple bed having a porous nanostructure with metal. The sweetness enhancer is selected from naringin dihydrochalcone, mogroside V, swingle extract, rubusoside, rubus extract, rebaudioside, and stevioside. The forecasting performance metrics are then stored in a database for access by a capacity planning system. Subsequently an epitaxial layer is formed in the sourcedrain recesses to provide stress on a channel region of the transistor locations.
