Abstract: A system for compressing an input data stream to create a compressed output data stream, comprising a memory for storing a hash table comprising hash entries each comprising a hash value of an associated subset of following data items of an input data stream and a pointer to a memory location of the associated subset. A processor coupled to the memory executes the following operations while instructing a SIMD engine to execute concurrently one or more of the operations for consecutive subsets: calculate the hash value for each subset, search the hash table for a match of each calculated hash value and update the hash table according to the match result. The processor then updates the compressed output data stream according to the match result and a comparison result depending on the match result and operations for the plurality of associated subsets to create the compressed output data stream.

Abstract: A flexible check valve for fluid-handling systems that prevents reverse flow but allows downstream flow of fluid comprises a dome that fits within a pipe and includes a concave surface. The flexible check valve further includes a flexible seat that fits within the pipe and includes a. convex surface. The flexible seat is deformable from a closed position, that prevents reverse flow, to an open position, that allows downstream flow, when an upstream pressure acts on the flexible seat and exceeds a downstream pressure and when, in the closed position, the concave surface of the dome is oriented downstream and the convex surface of the flexible seat is oriented upstream. A housing is connected to the dome and the flexible seat and is connectable to the pipe. A seal is formed between the concave surface and the convex surface when the flexible check valve is in the closed position.

Abstract: For producing digest block segmentations based on reference segmentations in a data deduplication system using a processor device in a computing environment, digests are calculated for an input data chunk. Data matches and data mismatches are produced based on matching input digests with reference digests. Secondary digest block segmentations are obtained from similar reference intervals for each of the data mismatches and applied to the input data.

Abstract: A system for tracking position of objects in an industrial environment includes an interrogator, a transponder, and a processor. The interrogator transmits a signal and provides a first reference signal corresponding to the transmitted signal. The transponder provides a response signal. The interrogator receives the response signal and provides a second reference signal corresponding to the response signal. The processor determines a location of either the interrogator or the transponder, relative to the other, based on the two reference signals.

Abstract: A computer-implemented method for recovering a digital image (x) from a sequence of observed digital images (y1, . . . , yT), includes: obtaining an observed digital image (yt); estimating a point spread function (ft) based on the observed image (yt); estimating the recovered digital image (x), based on the estimated point spread function (ft) and the observed image (yt); and repeating the above steps. In order to correct optical aberrations of a lens, a point spread function of the lens may be used.

Abstract: The present invention relates to the use of receptor tyrosine kinase (RTK) oligomers as markers of RTK activation and signalling. Methods are described based upon determining the presence of RTK oligomers and/or determining the nanometre spatial separation between RTK molecules assembled as RTK oligomers at the cell surface. Such methods are directed to the monitoring of RTK activation in cells and the detection of mutations in RTKs. Methods are also described for determining prognosis for subjects having diseases characterised by aberrant RTK activation and for selecting subjects for treatment with RTK inhibitors.

Abstract: Deduplicated data is packed into finite-sized containers. A similarity score is calculated between files that are similarly of the deduplicated data. The similarity score is used for grouping the similarly compared files of the deduplicated data into subsets for destaging each of the subsets from a deduplication system to one a finite-sized container. The similarity score is used for grouping the similarly compared files of the deduplicated data into subsets for destaging each of the subsets from a deduplication system to one of the finite-sized containers. An indication is received by a user of which of the similarly compared files are to be grouped into the subsets for destaging each of the subsets from a deduplication system to one of the finite-sized containers. Transitive closures are used for assisting with using the similarity score for grouping the similarly compared files of the deduplicated data into the sub sets.

Abstract: Input backup data is deduplicated with data of a synthetic backup previously constructed by a deduplication storage system. A synthetic backup is constructed by processing metadata instructions provided by a backup application. Deduplication digests are calculated based on the data of the synthetic backup and the deduplication digests are stored in a digests index. When new backup data is processed, deduplication digests of the new data are calculated and searched in the digests index. Matching digests of previously constructed synthetic backups are located in the digests index. Each of the located matching digest references stored data are included in the synthetic backup, and the stored data is similar to the input backup data. Data matches are found in the input backup data and data in the synthetic backup.

Abstract: For adding cooperative file coloring protocols in a data deduplication system using a processor device in a computing environment, a preferred character is represented for file coloring in a file using a code selected from a multiplicity of codes that represent a variety of contexts. The original meaning of the preferred character is retained when representing the preferred character for the file coloring by the code selected from the multiplicity of codes. The file is deduplicated by the data deduplication system according to the file coloring that represents a source file of a backup application.
