Abstract: A parameter estimator for estimating a set of parameters for pattern recognition has a recognizer for receiving a training set having members. The recognizer performs recognition on the members of the training set using a current set of parameters and based upon a predetermined group of elements. A set generator associated with the recognizer generates at least one equivalence set containing recognized members of the training set, which are used by a target function determiner associated with the set generator to calculate a target function using the set of parameters. A maximizer updates the parameter set so as to maximize the calculated target function.

Abstract: Alphabet-partitioned codewords, for example class based codewords, are decoded using a two-part decoder. The first part is a class code decoder that extracts, from the codeword, information for decoding the symbol code. The second part is a symbol code decoder that uses that information to decode the symbol code. If the symbol code is a literal, the symbol is just stripped from the codeword; otherwise, the symbol is retrieved from a symbol memory. Throughput of blocks of even numbers of codewords is enhanced by compressing first and second block halves oppositely and by using two decoders to decompress first and second block halves in parallel. Throughput is enhanced further by using extended codewords, each of which is a concatenation of class codes and symbol codes of several symbols.

Abstract: Apparatus for automated alignment of polymer structures, the polymer structures having predefined or non-predefined rigid portions and flexible portions. The apparatus comprises an input unit and a transforming unit, where the input unit receives a first polymer structure and a second polymer structure, and the transforming unit applies a semi-flexible transformation on at least a portion of the first polymer structure, at least a portion of the second polymer structure or at least portions of both the first and the second polymer structures. The transformation is done so as to at least partially superimpose the first polymer structure and the second polymer structure, hence to provide at least a partial alignment of the first and the second polymer structures.

Abstract: A method for spatial imaging of neuronal biological material using diffusion based magnetic resonance imaging (MRI) techniques. The method is comprised of (i) exposing a neuronal biological material region to a series of diffusion weighted MRI sequences producing plurality of non mono-exponential decay signals; (ii) analyzing the non mono-exponential decay signals and obtaining a parameter reflecting the diffusion characteristic of the slow diffusing component; and (iii) forming an array of these parameters thereby obtaining the spatial image of the neuronal biological material region.

Abstract: A method of compressing a dataset of distinct symbols, such as binary instructions, that all have a common length. The instructions are ranked by frequency. The most common symbols are classified according to a successive-powers-of-two class size scheme, and are compressed as concatenations of respective class codes and respective symbol codes. A literal class code is prepended to the remaining symbols. The associated codebook is a list of the classified symbols in rank order. To decompress the compressed symbols, the compressed symbols are parsed into their class codes and symbol codes, and the symbol codes are used as lookup indices for the codebook. The scope of the invention includes a computer with a fixed-instruction-length processor and one or more instruction storage areas where compressed instructions are stored and decompressed for execution.

Abstract: Methods, devices and pharmaceutical compositions for the controlled, non-surgical removal and retrieval of cells from a plurality of skin lesions and tissue surfaces are disclosed. A synergistic effect of proteolytic digestion of the intracellular matrix and “stripping” flow is achieved by treating a defined area with a controlled, continuous stream of proteolytic enzyme solution, causing gentle but effective tissue erosion. Isolated cells from the skin lesion and/or tissue surface may be collected from the protease solution stream for histological analysis and/or cell culture, affording a method of “enzymatic biopsy”. The protease solution may be supplemented with anesthetics, coagulants, anticoagulants and antibiotics to decrease the discomfort, erythema, bleeding, risk of infection and scarring traditionally associated with surgical treatment of skin lesions.

Abstract: More than 90% of mutations found in the p53 protein produce a conformational change in p53 which results in the exposure of an epitope, which is otherwise hidden in the hydrophobic core of the molecule. A single chain antibody (scFv) which specifically recognizes this common mutant epitope in mutant p53 but not in wild type p53 is disclosed. Also described are a DNA molecule encoding the scFv, pharmaceutical compositions comprising the antibody and methods of treatment using the pharmaceutical compositions.

Abstract: Human herpes virus (HHV) 7 is capable of binding to the CD4 antigen and the HHV-7 or a binding protein derived therefrom is thus useful as a CD4-ligand for various therapeutic applications. HHV-6 or HHV-7 are lymphotropic and are thus useful as lymphotropic vectors for delivering DNA into lymphocytes.

Abstract: A drug screening assay for identifying compounds for their potential effects on the long chain fatty acid dependant intracellular membrane anchorage sites of lipoproteins. Membranes-anchoring-target are incubated in the presence of the compound to be tested and the proportion of the target that is released by the compound is detected and quantitated. The benchmark for this assay are the prenylated proteins such as the farnesylated and palmitoylated oncogenic ras trigger proteins which are displaced from their anchorage at the intracellular plasma membrane by derivatives of Farnesyl Thiosalicylic Acid (FTS). The assay is adaptable to flexibly assay a large variety of anchored targets using a wide range of labeling and detection techniques in test wells, tissue culture, and in animals as injected cells or transgenic, thereby directly addressing a wide range of pharmacologically relevant needs.
