    Abstract: A system includes a gas chromatograph configured to determine experimental chromatographic data including retention times associated with samples. The system also includes a mass spectrometer configured to determine experimental mass spectral data associated with samples. The mass spectrometer can include a quadrupole field ion trap that uses a non-classical detection technique. The system determines a retention index for an unknown sample based upon retention times for a calibration sample and the unknown sample, and identifies reference mass spectral data using the retention index. The reference mass spectral data can include spectra measured using a classical detection technique. The system can compare the experimental mass spectral data to the reference mass spectral data using one or more comparison metrics, such as a percent fragment match and/or a variance match. A score can be determined to identify the unknown sample using one or more of the metrics.

    Abstract: A server in connection with a plurality of multimedia sources that has a plurality of clients. The server determines if at least one of the clients is requesting to receive at least one of the sources. The server then multicasts these requested sources to the requesting clients, respectively. If none of the clients is requesting a particular source, the server does not multicast that particular source. If all of the clients cease requesting a particular source that the server is currently multicasting, the server terminates the multicast of that particular source.

    Abstract: Described herein is a high-energy x-ray imaging system including a stationary gantry, a conveyor assembly configured to convey an object to be imaged through the gantry, a plurality of linear accelerators, a detector array, and a control system. The linear accelerators are arranged in an array within the gantry and are configured to generate high-energy x-ray fan beams to be transmitted through the object. The detector array is positioned opposite the linear accelerators and is configured to collect the high-energy x-ray fan beams transmitted through the object. The control system is configured to energize the linear accelerators according to a predetermined control sequence to generate the high-energy x-ray fan beams, and construct a 3-D image of the object based on data received from the detector array and representative of the high-energy x-ray fan beams transmitted through the object.

    Abstract: A detection device for detecting the presence of a substance of interest in a sample is described. The device can include a data store comprising executable instructions for at least one convolutional neural network, CNN, configured to process images: and a processor coupled to the data store and configured to execute the instructions to operate the at least one CNN. The detection device can be configured to: obtain spectrometry data, operate a first one of the CNNs to process the spectrometry data to obtain a first CNN output; apply a mask to the spectrometry data to obtain masked data; operate a second one of the CNNs to process the masked data to obtain a second CNN output; and determine if the substance of interest is present in the sample based on both the first CNN output and the second CNN output.
