Systems, devices, and methods for removing areas of tissue are described. The compounds are therefore useful in the treatment of IKK mediated diseases including autoimmune diseases inflammatory diseases and cancer. In one embodiment, a network switch identifies a virtual LAN carrying suspect data on a data trunk. This estimation is performed recursively for each level of a multiresolution decomposition pyramid until a reconstructed version of the data product is returned. The compounds are useful for treating caspase-mediated diseases. In a second mode in which a gray level having a smaller ON-resistance of a MOS transistor than that in the first mode is selected, the number of MOS transistors used in the first and second switch circuits for voltage division is increased.
