We describe and evaluate a Hierarchical Sparse Matrix (HiSM) storage format designed to be a unified format for sparse matrix applications on vector processors. The advantages that the format offers are low storage requirements, a flexible structure for element manipulations and allowing for efficient operations. To take full advantage of the format we also propose a vector architecture extensi...

Single-particle tracking (SPT) is widely used to study processes from membrane receptor organization to the dynamics of RNAs in living cells. While single-dye labeling strategies have the benefit of being minimally invasive, this comes at the expense of data quality; typically a data set of short trajectories is obtained and analyzed by means of the mean square displacements (MSD) or the distri...

In this paper we present some preliminary performance evaluations of the Block Based Compression Storage (BBCS) scheme, that consists of a sparse matrix representation format and an associated Vector Processor (VP) architectural extension, designed to alleviate the performance degradation experienced by VPs when operating on sparse matrices. In particular we address the execution of Sparse Matr...

Jensen-Shannon divergence (JD) is a symmetrized and smoothed version of the most important divergence measure of information theory, Kullback divergence. As opposed to Kullback divergence it determines in a very direct way a metric; indeed, it is the square of a metric. We consider a family of divergence measures (JDα for α > 0), the Jensen divergences of order α, which generalize JD as JD1 = J...

The aim of this study was to determine phenotypic and genotypic distances in parental lines of diallel population of sunflower, and to identify correlation between both distances with F1 performance, specific combining ability (SCA) and absolutely mid-parent heterosis. The morphological distance (Euclidean distance; EDs) and genetic distance (Jaccard`s distance; JD) among five sunflower parenta...

Johne's disease (JD) is a chronic enteric infection of cattle caused by Mycobacterium avium subsp. paratuberculosis (MAP). The high economic cost and potential zoonotic threat of JD have driven efforts to develop tools and approaches to effectively manage this disease within livestock herds. Efforts to control JD through traditional animal management practices are complicated by MAP's ability t...

It is estimated that 200 children per day worldwide develop Juvenile Diabetes (JD). There is no cure for JD, therefore treatment protocols focus on controlling the disease. Several information systems (IS) have been developed to help patients manage their chronic diseases, but often these systems suffer from reduced use over time or complete abandonment. Limited research has been conducted that...

Mycobacterial infection has been linked to the generation of autoantibodies, including anti-neutrophil cytoplasmic autoantibodies (ANCA), in clinical studies and small animal models. In an attempt to identify antibodies that react with both self and mycobacterial antigens in naturally infected ruminants, we generated a phage display library comprising single chain antibody fragments (scFv) from...
