A method of lubricating MEMS devices using fluorosurfactants 42. The test plug tool includes a test plug of an appropriate diameter used to pressure test the pressure control stack as well as a joint between any one of a surface casing and the wellhead, an intermediate casing and an intermediate casing mandrel, and a production casing and a production casing mandrel. The program verify operation can be selectively skipped in some program loops based on a voltage increment of one or more of the program pulse operations, an amount by which threshold voltages of the selected memory cells are to be increased in the ISPP scheme, or a total number of program loops of the ISPP scheme. A plurality of hypotheses may be determined for the character cluster, where each hypothesis is based on a subset of the bifurcation points and comprises a set of words generated from the character cluster. This invention also relates to pharmaceutical compositions containing these compounds.
