Abstract: A system and method for preprocessing magnetic resonance spectroscopy (MRS) data of brain tissue for pattern-based diagnostics is disclosed. The MRS preprocessing system includes an MRS preprocessing module that executes an operation that normalizes MRS spectrum data, recalibrates and scales the normalized MRS spectrum data, and then renormalizes the scaled MRS spectrum data. The resulting preprocessed MRS data is used to assist in identifying abnormalities in tissues shown in MRS scans.

Abstract: Disclosed is a mass spectrometer for analyzing a sample that has or is suspected of having microorganisms. The disclosed mass spectrometer has been uniquely configured to include a sample platform which functions as a counter electrode or discharge electrode and a surface to provide the sample to be analyzed. The mass spectrometer also includes an ion source positioned adjacent to the sample platform for ionizing and volatizing molecules within the sample, wherein the sample platform and the ion source are positioned such that during operation of the mass spectrometer an electrical discharge takes place between the ion source and the sample platform. Also disclosed are methods for generating a mass spectrum profile/fingerprint of a sample. The methods include positioning a sample platform having a sample adjacent to an ion source.

Abstract: This invention relates to a coated powder material containing a powder material having a surface layer that has been chemically immobilized with one or more surface-active agents and coated with an oil. The surface-active agents are present in an amount of at least about 0.1% by weight, based on the powder material; the oil is present in an amount ranging from about 0.1 to 180% by weight, based on the powder material; and the combined weight percentage of the surface-active agents and oil is at least about 4.0% by weight, based on the powder material. The oil-absorption rate of the powder material ranges from about 0.01 to about 0.70 gram of oil per gram of dry powder. The coated powder material is useful as a cosmetic.
