Title: Method and apparatus for finding differences between two computer files efficiently in linear time and for using these differences to update computer files
Inventor: JONES KERRY N
IPC: G06F8/658
Filed: 2004-05-05
Granted: 2010-07-20
Abstract: A method of updating a computer file from an old file into a new file comprises blocking the new file and the old file into fixed-sine blocks, maintaining a window (collection of contiguous blocks) for each file on which lookup preprocessing has been performed, and performing match processing on each new file block in turn (comparing against both the old and new windows) using a key-sampling technique combined with approximate matching. For each new file block, the match information is then optimized for coding efficiency and encoded onto a patch file that describes an algorithm for converting the old file into the new file. The patch file application method and apparatus then performs the algorithm described in the patch file, The method uses a fixed amount of random-access memory regardless of the sizes of the two files and uses a temporary mass storage. In addition, the method has a running time roughly proportional to the size of the new file and allows the use of parallel processing to reduce the time required. The system and method produce patch files which are smaller than prior systems and methods, and allow the operator of the apparatus to perform an efficiency/effectiveness trade-off.

Abstract: Novel techniques for the detection of Aspergillus in samples are disclosed.  These techniques relate to PCR amplification and/or detection of Aspergillus ITS1 rDNA sequences, and the identification of particular species of Aspergillus by detecting differences in the ITS1-V1, ITS-V2, ITS-V3, ITS-V4, and ITS-V5 nucleic acid sequences of Aspergillus. The highly variable regions of the ITS1 rDNA sequences are particularly useful in distinguishing, for example, Aspergillus clavatus, Aspergillus granulosus, Aspergillus sydowii, Aspergillus flavipes, Aspergillus restrictus, Aspergillus versicolor, Aspergillus wentii, and Aspergillus chevalieri. In particular embodiments, the sequence differences are also able to distinguish among variants of particular species, such as Aspergillus granulosus CBS 119.5A, Aspergillus granulosus strain NRRL 1932, Aspergillus sydowii strain NRRL 250, Aspergillus sydowii strain NRRL 4768, Aspergillus sydowii strain CUHI, Aspergillus sydowii strain CUH2, Aspergillus sydowii strain CUH7, and Aspergillus sydowii strain CUH8.

Title: Short chain polymer for enhancing the bioadhesiveness of polymers on mucosal membrane
Inventor: SANTOS CAMILLA A
IPC: A61K47/38
Filed: 2003-05-15
Granted: 2010-02-09
Abstract: Methods and compositions are provided for enhancing the bioadhesive properties of polymers used in drug delivery systems. The bioadhesive properties of a base polymer are enhanced by incorporating a short chain polymer with one or more free carboxylic groups into the base polymer to enhance the ability of the base polymer to adhere to a tissue surface such as a mucosal membrane. The short chain polymers can be incorporated within a wide range of base polymers including proteins, polysaccharides and synthetic biocompatible polymers. In one embodiment, short chain polymers can be incorporated within base polymers used to form or coat drug delivery systems, such as microspheres, which contain a drug or diagnostic agent. The short chain polymers can either be solubilized and blended with the base polymer before manufacture or else used as a coating with base polymers over existing systems. The base polymers, for example in the form of microspheres, have improved ability to adhere to mucosal membranes, and thus can be used to deliver a drug or diagnostic agent via any of a range of mucosal membrane surfaces including those of the gastrointestinal, respiratory, excretory and reproductive tracts.

Title: Non-parametric matched filter receiver for wireless communication systems
Inventor: FERNANDEZ-CORBATON IVAN JESUS
IPC: H04L25/02
Filed: 2003-07-18
Granted: 2010-06-01
Abstract: A non-parametric matched filter receiver that includes a digital (e.g., FIR) filter and a channel estimator. The channel estimator (1) determines the timing to center the digital filter, (2) obtains the characteristics of the noise in received samples, (3) estimates the system response for the samples using a best linear unbiased (BLU) estimator, a correlating estimator, or some other type of estimator, and (4) derives a set of coefficients for the digital filter based on the estimated system response and the determined noise characteristics. The correlating estimator correlates the samples with their known values to obtain the estimated system response. The BLU estimator pre-processes the samples to whiten the noise, correlates the whitened samples with their known values, and applies a correction factor to obtain the estimated system response. The digital filter then filters the samples with the set of coefficients to provide demodulated symbols.
