20130142863 | PHOSPHATIDYLCHOLINE LIPID LIPOSOMES AS BOUNDRY LUBRICANTS IN AQUEOUS MEDIA - The invention provides a method for lubricating one or more surfaces, comprising applying gel-phase liposomes onto said one or more surfaces, wherein the temperature of said surface(s) at the time of lubrication is below the phase transition temperature Tm of said liposomes. The method can be used for lubricating non-biological surfaces, and also for lubricating the surfaces of a biological tissue in a mammalian subject, e.g., for treating joint dysfunction. | 06-06-2013 |

20090234821 | Systems and Methods for Efficient Data Searching, Storage and Reduction - Systems and methods enabling search of a repository for the location of data that is similar to input data, using a defined measure of similarity, in a time that is independent of the size of the repository and linear in a size of the input data, and a space that is proportional to a small fraction of the size of the repository. The similar data segments thus located are further analyzed to determine their common (identical) data sections, regardless of the order and position of the common data sections in the repository and input, and in a time that is linear in the segment size and in constant space. | 09-17-2009 |

20120131082 | COMPUTATION OF A REMAINDER BY DIVISION USING PSEUDO-REMAINDERS - Methods, computer systems, and computer program products for calculating a remainder by division of a sequence of bytes interpreted as a first number by a second number is provided. A pseudo-remainder by division associated with a first subsequence of the sequence of bytes is calculated. A property of this pseudo-remainder is that the first subsequence of the sequence of bytes, interpreted as a third number, and the pseudo-remainder by division have the same remainder by division when divided by the second number. A second subsequence of the sequence of bytes interpreted as the first number is appended to the pseudo-remainder, interpreted as a sequence of bytes, so as to create a sequence of bytes interpreted as a fourth number. The first number and the fourth number have the same remainder by division when divided by the second number. | 05-24-2012 |

20120158812 | PARALLEL COMPUTATION OF A REMAINDER BY DIVISION OF A SEQUENCE OF BYTES - Methods, computer systems, and computer program products for calculating a remainder by division of a sequence of bytes interpreted as a first number by a second number are provided. A first remainder by division associated with a first subset of the sequence of bytes is calculated with a first processor. A second remainder by division associated with a second subset of the sequence of bytes is calculated with a second processor. The calculating of the second remainder by division may occur at least partially during the calculating of the first remainder by division. A third remainder by division is calculated based on the calculating of the first remainder by division and the calculating of the second remainder by division. | 06-21-2012 |

20140188818 | OPTIMIZING A PARTITION IN DATA DEDUPLICATION - For optimizing a partition of a data block into matching and non-matching segments in data deduplication using a processor device in a computing environment, an optimal calculation operation is applied in polynomial time to the matching segments for selecting a globally optimal subset of a set of matching segments according to overhead considerations for minimizing an overall size of a deduplicated file by determining a trade off between a time complexity and a space complexity. | 07-03-2014 |

20140188828 | CONTROLLING SEGMENT SIZE DISTRIBUTION IN HASH-BASED DEDUPLICATION - Segment sizes are controlled by setting the size of a segment boundary in a hash-based deduplication system. A subsequence of size K of a sequence of characters S is set. An increasing sequence of n probabilities and a corresponding sequence of n decreasingly restrictive logical tests are chosen to be applied on the sequence of characters S. Segment boundaries are set by using the sequence of the decreasingly restrictive logical tests by deciding to declare a segment boundary at a current position if one of the sequence of the decreasingly restrictive logical tests, with a corresponding probability of the sequence of n probabilities, returns a true value when applied on the sequence of characters S. | 07-03-2014 |

20130198753 | FULL EXPLOITATION OF PARALLEL PROCESSORS FOR DATA PROCESSING - For full exploitation of parallel processors for data processing, a set of parallel processors is partitioned into disjoint subsets according to indices of the set of the parallel processors. The size of each of the disjoint subsets corresponds to a number of processors assigned to the processing of the data chunks at one of the layers. Each of the processors are assigned to different layers in different data chunks such that each of processors are busy and the data chunks are fully processed within a number of the time steps equal to the number of the layers. A transition function is devised from the indices of the set of the parallel processors at one time steps to the indices of the set of the parallel processors at a following time step. | 08-01-2013 |
