  • Publication number: 20160110500
    Abstract: System and methods are provided for performing privacy-preserving, high-performance, and scalable DNA read mapping on hybrid clouds including a public cloud and a private cloud. The systems and methods offer strong privacy protection and have the capacity to process millions of reads and allocate most of the workload to the public cloud at a small overall cost. The systems and methods perform seeding on the public cloud using keyed hash values of individual sequencing reads' seeds and then extend matched seeds on the private cloud. The systems and methods are designed to move the workload of read mapping from the extension stage to the seeding stage, thereby ensuring that the dominant portion of the overhead is shouldered by the public cloud.

  • Publication number: 20160080749
    Abstract: Methods and devices for encoding and decoding video are described that partition transform blocks into coefficient groups. The coefficients within non-zero coefficients are run-length coded in a reverse scan order within the group. Prior to coefficient coding, data is encoded indicating which coefficient group in group scan order is the last to contain a non-zero coefficient. Then data is encoded indicating the position within that last non-zero coefficient group of the last non-zero coefficient in scan order inside the coefficient group. Thus the decoder is able to decode run-length data knowing the positions of the coefficients and eliminating the need for end-of-block flags.

  • Publication number: 20160073130
    Abstract: Methods and devices for video coding are described. When encoding a non-zero coefficient group (CG) prior to the last such group in a group scan ordering within a transform block, data representative of the true (x,y)-position of the last non-zero transform coefficient in a scan ordering within that CG is modified, to improve coding efficiency, based upon at least one of (a) an intra-prediction mode used to encode the block and (b) at least one coefficient group neighbouring that CG. Upon decoding a CG thus encoded, the modification is un-done to retrieve the true (x,y)-position.

  • Patent number: 9211070
    Abstract: Systems, methods, and products for determining indicated blood pressure values and/or characterizing a condition of a patient. The systems, methods, and products are capable of determining indicated blood pressure values in a lower extremity of a patient using an oscillometric technique. An oscillometric signal obtained from the lower extremity of the patient is analyzed, and the patient may be classified into one of a plurality of diagnostic classes. Each diagnostic class may have an associated ratio value. Based on the diagnostic class into which the patient is classified, a selected lower extremity characteristic ratio may be selected. A lower extremity indicated blood pressure value may be obtained by oscillometric processing using the selected ratio. This lower extremity indicated blood pressure value may be used with an upper extremity indicated blood pressure value to perform an extremity blood pressure ratio (EBPR) examination.

  • Publication number: 20150358621
    Abstract: Methods and devices for encoding and decoding video using mode-dependent context determination in the case of level-run pair coding of transform coefficients are described. Intra-coding modes may be grouped into classes and each class may be associated with a partitioning of a coefficient group into regions. The region in which a coefficient falls determines, in part, the context selected for encoding bins associated with that coefficient, including a level, if the coefficient is non-zero, and a run if the coefficient correspond to the bin of a binarized run value.

    Abstract: Methods of encoding and decoding video are described. The encoder and decoder include a buffer storing at least two context model states, each being the context model state after context-adaptive encoding/decoding of a respective previously-encoded/decoded picture. One of the at least two stored context model states is selected from the buffer and used to initialize the context model for context-adaptively decoding a current picture. The current picture is then context-adaptively entropy encoding/decoded.
