In this paper we describe block algorithms for the reduction of a real symmetric matrix to tridiagonal form and for the reduction of a general real matrix to either bidiagonal or Hessenberg form using Householder transformations. The approach is to aggregate the transformations and to apply them in a blocked fashion, thus achieving algorithms that are rich in matrix-matrix operations. These red...

Positive and negative selection on indel variation may explain the correlation between intron length and recombination levels in natural populations of Drosophila. A nucleotide sequence analysis of the 3.5 kilobase sequence of the alcohol dehydrogenase (Adh) region from 139 Drosophila pseudoobscura strains and one D. miranda strain was used to determine whether positive or negative selection ac...

The purpose of this study was to investigate the effect of process conditions on the properties of instant grain base. A blend of wheat, mungbean and groundnut was used in the study. The effects of feed moisture, barrel temperature and screw speed on product responses viz. specific mechanical energy (SME), expansion ratio (ER), density (D), water absorption index (WAI) and water solubility inde...

OBJECTIVE Dural sac cross-sectional area (DSCSA) is a way to measure the degree of central spinal canal compression. The objective was to investigate the correlation between the expansion ratio of DSCSA after unilateral laminotomy for bilateral decompression (ULBD) and the clinical results for lumbar spinal stenosis. METHODS We retrospectively reviewed the clinical data and radiographs of 103...

Abstract Background Stent under-expansion is the potent predictor for stent thrombosis. Purpose We aim to determine incidence of and its predictors in patient who undergoing rotational atherectomy (RA) assisted percutaneous coronary intervention (PCI) assessed by optical coherence tomography (OCT). Method The study included 83 consecutive patients OCT guidance RA PCI during January 2016 through...

Motivated by the weak-strong coupling expansion [1], we calculate the spectrum of hadrons using a systematic 1/d (d-dimensionality of spacetime) in addition to a strong coupling expansion in β. The 1/d expansion is pushed to the next to leading order in (1/d) for mesons and next to next to leading order for baryons. We do the calculation using Wilson fermions with arbitrary r and show that doub...

In this article, we develop new closed-form asymptotic approximations for the average symbol error rate (ASER) and the outage probability performance metrics of digital communication systems impaired by additive white Gaussian noise and fading. Specifically, our expressions generalize some of the known asymptotic results to a wide range of fading environments and digital modulation schemes. We ...

Background. To promote patient-centered care, it is important to understand the impact of sociodemographic factors on procedure choice for women undergoing postmastectomy breast reconstruction. In this context, we analyzed the effects of these variables on the reconstructive method chosen. Methods. Women undergoing postmastectomy breast reconstruction were recruited for the prospective Mastecto...

Analytic approximations for percolation points in two-dimensional and threedimensional particulate arrays have been reported for only a very few, simple particle geometries. Here, an analytical approach is presented to determine the percolative properties (i.e. statistical cluster properties) of permeable ellipsoids of revolution. We generalize a series expansion technique, previously used by o...
