Abstract: A capillary absorption spectrometer and process are described that provide highly sensitive and accurate stable absorption measurements of analytes in a sample gas that may include isotopologues of carbon and oxygen obtained from gas and biological samples. It further provides isotopic images of microbial communities that allow tracking of nutrients at the single cell level. It further targets naturally occurring variations in carbon and oxygen isotopes that avoids need for expensive isotopically labeled mixtures which allows study of samples taken from the field without modification. The process also permits sampling in vivo permitting real-time ambient studies of microbial communities.

Abstract: Controlling a byte code transformer on detection of completion of an asynchronous command. An asynchronous command is received by an asynchronous manager from a test framework. The asynchronous command manager issues the asynchronous command to an application. A transformer is loaded for transforming byte code associated with the application in order to output one or more method names and associated timestamps of one or more method entry points and one or more method exit points. A check is made as to whether an expected result has been generated by the application. In response to determining that an expected result has been successfully generated, a time period associated with successful generation of the expected result is compared with the timestamps in order to determine matching timestamps and associated matching method names. The transformer is modified in accordance with the matching method names such that a subsequent transformation executes on byte code associated with the matching method names.
