Abstract: In a first exemplary embodiment of the present invention, a method is provided for marking a sample of a doped crystalline material. According to a feature of the present invention, the method comprises the steps of causing a controlled alteration to the crystalline material at a preselected spot on the sample of the crystalline material, sufficient to cause a change in a cathodoluminescence spectrum of the crystalline material at the preselected spot and utilizing the altered cathodoluminescence spectrum to mark the crystalline material.

Abstract: In an embodiment according to the present invention, a coronagraph for detecting reflective bodies external to a light source is provided. A first mirror for directing a beam of light onto an occulting mask is adjusted based on a data from a fiber optic sensor or a second sensor. An occulting mask for separating the beam into a first and second portion directs the first portion onto a fiber optic sensor and the second portion onto a Lyot stop. The occulting mask is adjustable based on data from the second sensor. The Lyot stop separates the second portion of the beam into a third and fourth portion. The Lyot stop also directs the third portion of the beam onto the second sensor and the fourth portion of the beam onto a camera for detecting one or more reflective bodies external to a light source.

Abstract: A method for selecting a sequence is provided. A set of sequences are defined, each one of the sequences comprising one or more characters. A sub-set of the set of sequences are evaluated with a dynamic programing method to obtain a numeric indicia of merit. Additional sequences are added into the sub-set of sequences. The steps of defining, evaluating, and adding are repeated until the numeric indicia is substantially constant or there are no more additional sequences. One or more of the sequences are selected based on the numeric indicia.

Abstract: The present invention provides a method and compositions for species identification from small samples of fish tissue. The method includes the use of the polymerase chain reaction (PCR) to amplify regions of the mitochondrial genome from total cellular DNA with species-specific primers and subsequent analysis of the PCR products. The method provides an accurate and rapid determination of the species of origin for a single egg of processed caviar. Compositions for PCR primers specific for 27 species of sturgeon are provided.
