In certain embodiments, methods of the present invention obtain dynamic data sets of an NMR spectroscopy signal of polarized 129Xe in a selected structure, environment, or system. The method includes the steps of initially designing the set of test vectors, and selecting one of multiple available coding schemes for each test vector wherein at least two of the coding schemes selected for encoding are different from one another, and wherein one of the available coding schemes represents non-encoded data. When the valve element is in the rest position, fluid flow between the inlet opening and the outlet aperture is permitted at a relatively low rate. Articles for applying the compositions to produce by spraying are disclosed. The circuit substrate is pushed, thereby the clamp is pushed by the circuit substrate to disengage the bent portions of the upper contacts and attached to the housing. In addition, a threshold used for switching an LUT is caused to be different depending on a switching direction between LUTs, thereby suppressing frequent occurrence of switching of the LUT.
