Abstract: A data analysis method for a component separation/tandem mass spectrometer system, including first and second MS steps which data therefrom includes respective sample components (MS1-SC, MS2-SC), includes analyzing per sample a data set for MS2-SC to determine mass-to-charge ratio and retention index (m/z-RI) for each MS2-SC. m/z-RI for each MS2-SC is compared to a known compound library and matching MS2-SC removed from the data set, the remaining MS2-SC being candidate MS2-SC. Clusters are formed across the candidate MS2-SC, each having m/z-RI within respective ranges per cluster. For each sample within each cluster, MS1-SC within the cluster ranges are retrieved. For each cluster, at most one consensus MS1-SC represents each sample, with corresponding consensus MS2-SC and m/z-RI, and designated as a molecular ion or derivative thereof. Clusters are grouped by consensus RI and candidate clusters from each group are selected and correlated by consensus parameters with an unknown compound.

Abstract: A method, apparatus, and computer-readable storage medium for analyzing component separation/mass spectrometer data for a sample having known characteristic includes analyzing reference ion data for a relationship between ion mass, retention time, and intensity. The analyzed data is added to a repository, wherein each ion therein has an intensity maxima within a characteristic retention time range for a characteristic ion mass. If the reference ion is in the repository, the range is modified according to the characteristic retention time of the reference ion intensity maxima. Based on the known characteristic, an ion expected in the sample is selected from the repository, and sample data is compared to data for the ion selected from the repository to determine whether the ion is present in the sample. The range in the repository is then modified according to the characteristic retention time of the intensity maxima for the ion present in the sample.

Abstract: Various systems and methods for selecting candidate biological components and/or combinations of biological components that affect a biological process are described. For example, a computing device may use a computer model to simulate the biological process and predict a phenotypic outcome. In this manner, the impact of candidate components and combinations may be determined using the computer model. The computing device may determine optimal characteristics such as expression levels of biological components that result in a desirable phenotypic outcome of the biological process as predicted by the computer model. The computing device may perform sensitivity analysis around the optimal characteristics. The sensitivity analysis may be used to determine whether the candidate combinations are robust across a range of the optimal characteristics. The computing device may select various candidate components and combinations based on the sensitivity analysis and the predicted phenotypic outcome.

Abstract: A communication system is provided for increasing communication range between at least two radio communication devices without increasing the output power of transmitted radio signals from the devices, and without increasing the antenna gain of the received signals. Each radio device includes an oscillator for generating a carrier reference signal, and an SATPS receiver which receives at least one standard timing reference signal from at least one SATPS satellite. The received standard timing reference signal is used to continuously adjust the timing and synchronization of the oscillator to improve the accuracy of the carrier frequency signal. The improved accuracy in the carrier frequency signal may then be used to reduce the bandwidth of the modulated carrier frequency signals generated by the radio device to thereby increase the effective communication range and sensitivity of the device.
