Abstract: Technologies for producing efficient investigation routes for identifying gas leak locations include a mobile compute device. The mobile compute device includes circuitry configured to obtain route data indicative of a route to be traveled along to identify a location of a gas leak. The circuitry is also configured to present the route data to a user to guide the user along the route.

Abstract: Systems and methods for efficiently identifying gas leak locations may include traversing, by an investigator and within a search area in which a gas leak has been indicated, a route defined according to at least one of a surge-cast algorithm or a surge-spiral algorithm. The systems and methods may also include sampling, with a gas detection device carried by the investigator, an environment along the route to identify a location of the gas leak.

Abstract: The invention includes prognostic and diagnostic methods and compositions for characterizing disease states, biopsy samples, biological samples, cells, and tissues. In various embodiments of the invention, a bioassay may be used to analyze the activity of the androgen receptor (AR) in human prostate epithelial (HPE) cells derived from patient samples. The activity of the AR may be used to characterize the sample in regard to AR activity. Characterization of a sample may be useful in classify the sample and/or in determining a treatment regiment. In other embodiments, a sample may be compared to other known samples to identify other distinguishing characteristics, such as disease markers, and/or determine a treatment regiment based on the comparison of samples.
