Abstract: Novel and efficient syntheses create novel piperazinone intermediates which facilitate the production and use of PNAs. Such syntheses and the products enhance the feasibility of a system which permits the rapid identification of PNA oligomers useful as therapeutics, diagnostics and/or gene characterization tools. A first component of the system is a universal PNA library that most preferably incorporates one or more universal nucleotide bases into carefully selected positions within each oligomer species thereby providing the library with the screening ability of a much larger library. The second component of the system is a high throughput screening system that includes a number of assays designed to provide information on the binding activities of the different PNAs to a target nucleotide sequence (generally, a DNA or RNA sequence). The third component is a software system especially designed to provide rapid analysis of the data collected from the high throughput screening system and to determine therefrom the sequence base identities and sequence lengths of PNA oligomers most likely to bind to and appropriately affect the target molecule.

Abstract: PURPOSE: A method for extracting an iris area using a multi-resolution active contour model is provided to extract an iris area accurately in accordance with a movement and a rotation of an iris image and variation of a size and a shape of the iris image. CONSTITUTION: An iris image of a user is acquired through an image acquisition device of a contactless infrared ray method(S100). A resolution of the acquired iris image is degraded using a low-pass filter(S110). An internal boundary is extracted in the resolution-degraded iris image using an infrared ray illumination and a structural characteristic of the pupil of the eye(S112). 'N' number of initial points are extracted on the internal boundary(S114). An active contour model application with respect to the 'N' number of initial points is executed(S116). The active contour model application is executed repeatedly until the changed resolution is returned into the original resolution(S118). As a result of the repetitious active contour model application, an accurate internal boundary and the center are extracted(S120). An external boundary and the center of the iris image are extracted(S122).
