A method for identifying the cause of degraded IO performance between a host system and a storage controller includes initially monitoring IO performance between the host system and the storage controller. Received signals are detected by preprocessing the signals detected at each antenna with signals detected by the antenna at the immediately previous frame, and then applied to a maximum likelihood detector circuit, followed by an inverse mapping circuit. An execution context needed for each script in the CCM operation declaration is prepared. When the transverse slider is slid, a separating protrusion pushes a chamfer to widen the distance between the holding magnet and the key magnet. LC compounds having a chiral nonracemic tail of this general formula have large dipoles ) and when doped into hosts such as achiral smectic C FLC hosts, lead to improved switching speeds of the FLC materials.
