Abstract: Methods, systems, and devices for reserving a reservable asset using a mobile device. A mobile device communicates directly with a vehicle-associated control module or through a reservation server using either a TCP/IP communications channel or near-field communications. A member enters a request using the user interface provided by the mobile-device application. The identity of the member is validated the vehicle-associated control module executes the request by sending a signal to a computer or sensor in the vehicle through the vehicle wiring or the vehicle CANbus. The request can be a function, such as unlocking the vehicle doors, illuminating the interior or exterior lights, honking the horn, or activating a panic alarm.

Abstract: Methods and apparatuses for deriving the sequence of an oligomer. In one exemplary method for deriving the sequence of a polypeptide, a predetermined set of mass/charge values for amino acid sequences is stored. An abundance value from mass spectrum data for each mass/charge value in the predetermined set is determined to produce a plurality of abundance values. A first ranking, based on the plurality of abundance values, is calculated for each sequence of a set of amino acid sequences having a first number of amino acids. A second ranking, based on the plurality of abundance values, for each sequence of a set of amino acid sequences having a second number of amino acids is calculated. A cumulative ranking, based on the first ranking and the second ranking, is calculated for each sequence of a set of amino acid sequences having at least the second number of amino acids.

Abstract: A mass spectrometry ionization method in which electrospray droplets or solid sample matrices are exposed to an ion beam thereby increasing the unbalanced charge of the analyte is provided. In another embodiment, a mass spectrometry ionization method in which ionization of the sample is achieved by directing an ion beam at a liquid or solid sample matrix containing analyte thereby ionizing and adding unbalanced charge to the analyte is provided.

Abstract: Novel methods and apparatuses are provided for use in identifying glucose metabolic products and determining metabolic flux by administering D7-glucose to a subject.

Abstract: The present invention provides methods and apparatus for purifying metabolites of interest and conducting metabolic analyses. The methods generally involve determining metabolic flux values for a plurality of target analytes by monitoring the relative isotope abundance of a stable isotope in a substrate labeled with the stable isotope and/or one or more target metabolites formed through metabolism of the labeled substrate. Certain methods utilize multiple electrophoretic methods to separate the target analytes from other components within the sample being analyzed. The methods can be used in a variety of applications including screens to identify metabolites that are correlated with certain diseases and diagnostic screens for identifying individuals having, or susceptible to, a disease.

Abstract: The invention provides methods, compositions, apparatus, and a computer data retrieval system for conducting proteomics.
