Abstract: A method, apparatus and computer program product for storing data in a disk storage system is presented. A dictionary data structure is defined and stored on the disk storage system. Key-value pairs can be inserted and deleted into the dictionary data structure, with full transactional semantics, at a rate that is faster than one insertion per disk-head movement. Keys can be looked up with only a logarithmic number of transfers, even for keys that have been recently inserted or deleted. Queries can be performed on ranges of key-value pairs, including recently inserted or deleted pairs, at a constant fraction of the bandwidth of the disk. The dictionary employs indirect logging for physical block logging.

Abstract: Method and apparatus for securing biometric data using multiple biometrics. The method includes the steps of: a) converting a first biometric to an irreversibly altered biometric using a parameterized transform function and b) prior to said conversion parameterizing a non-invertible transform function using at least one additional biometric. The apparatus is an apparatus for converting a first biometric to an irreversibly altered biometric using a parameterized non-invertible transform function comprising a computer containing a program for calculating the irreversibly altered biometric based upon input of a first biometric into the parameterized non-invertible transform function.

Abstract: A computer based method of biometric analysis which compares a first vector from a first biometric sample with a second vector from a second biometric sample. The vectors have at least one biometric feature. A method which compares two biometric samples. The samples form at least one cluster of at least one vector based on feature similarities between the samples. An apparatus incorporating a means for performing the method taught herein. A computer-readable medium and a propagated computer data signal transmitted via a propagation medium, with instructions which when executed by a processor, carry out the method of the present invention. A method of handwriting analysis which calculates a first metric from a first vector having at least one feature from a sample, calculates a second metric from a second vector having at least one feature from a second sample, and calculates the distance in two-dimensional feature space between metrics.

Abstract: A system and method are provided for generating a three-dimensional visualization image of an object such as an organ using volume visualization techniques and exploring the image using a guided navigation system that allows the operator to travel along a flight path and to adjust the view to a particular portion of the image of interest in order, for example, to identify polyps, cysts or other abnormal features in the visualized organ; where imaging data sets are acquired using conventional two-dimensional scans of the object in both a supine and prone orientation, and correspondence between the respective data sets is determined to permit jumping from one visualization orientation to the other while remaining at the same virtual location within the organ.

The antigen recognized by mAb 50-6 and mAb 1A-5 has been identified as the PETA-3 antigen. The antigen recognized by mAb 41-2 has been identified as a novel tumor metastasis-associated antigen. Compositions and methods are provided that are useful for treating and diagnosing metastatic tumors.

Abstract: A novel meiosis-specific gene sequence from Arabidopsis thaliana including the promoter region is described. When operably linked to a heterologous gene or to the antisense of the MEI1 gene, the normal meiotic events which give rise to viable pollen can be altered. Transgenic male sterile plants can thereby be produced by the manipulation of gene expression using a genetic regulatory element such as the one described herein.

Abstract: A novel three dimensional surface contouring method has been developed based on the fall-field fringe projection technique. A digital video projection system is used to project digitally created fringe patterns onto the object. The fringe pattern distorted by the geometry of the object surface is then captured by a high resolution CCD camera. To increase contouring resolution, purely software-based digital phase shifting technique is used, which eliminates the need for accurate positioning systems in the traditional phase shifting methods. The surface is reconstructed by applying the phase wrapping and unwrapping algorithms.

Abstract: A method of preparing a conjugated polymer which includes: determining a first intermolecular repeat distance and a first tilt angle relative to the translation axis for a guest molecule having a first atom and a second atom; selecting a host molecule having a second intermolecular repeat distance and a second tilt angle relative to the translation axis; synthesizing the host molecule and the guest molecule to form a co-crystal, wherein the first and the second repeat distances and the first and the second tilt angles are about equal so that when said host molecule and said guest molecule are synthesized the first atom and the second atom of adjacent guest molecules are in near van der Waals contact; and polymerizing the co-crystals to form the conjugated polymer. In a preferred embodiment, the guest molecule is a polytriacetylene and the host molecule has an intermolecular repeat distance of from about 6.0 Å to about 8.
