Apparatus and method for efficiently arranging and searching data in a memory space, such as a cache memory of a data storage array controller. At least one of the keys includes a key magnet, and a holding magnet is mounted on a transverse slider. 3% to the conductor cable portion after it has been heat-treated to form the superconducting compound, thereby separating the individual superconducting strands the chrome coat on which sintered as the result of heat treatment and further characterized in that the applied bending or twist strain is thereafter reverted to 0. Near diffraction-limited coherent multi-mode amplifiers can be conveniently cladding pumped, allowing for the generation of high average power. In another aspect the method can be used to combat fungal contamination of a site e.
