A method of querying a structure of compressed data comprising records stored as a forest of binary includes the step of generating an instruction set allowing a specified data value with a binary tree to be retrieved, given input of an address in memory that identifies the binary tree. A sensing film includes carbon nanotubes and the polymer. Because the fluorophore-linked chloramphenicol reduces its fluorescence upon binding to the active site and vice versa increases its fluorescence upon being displaced from the active site by the presence of unmodified chloramphenicol in a sample, the increase of fluorescence caused by a testing sample indicates the presence of chloramphenicol. PSCs respectively associated with cells can have different positions in the symbol sequences, and SSCs can respectively be phase shifted at different angles to facilitate detection and identification of a cell, where a PSC can be utilized as a phase reference by the associated SSC. Reaction mixtures, articles made therefrom, and methods of dynamically vulcanizing are also disclosed.
