The Bulk-Synchronous Parallel (BSP) model was proposed by Valiant as a standard interface between parallel software and hardware. In theory, the BSP model has been shown to allow the asymptotically optimal execution of architecture-independent software on a variety of architectures. Our goal in this work is to experimentally examine the practical use of the BSP model on current parallel archite...

DEFINITION Binary space partitioning (BSP) is a technique for recursively subdividing a space into convex sets by hyperplanes. The subdivision can be represented by means of a tree data structure known as a BSP tree. A BSP tree is thus a Point Access Method. Each node in a BSP tree represents a hyperplane which divides the space into two halves. It also contains references to two nodes which re...

The model of bulk-synchronous parallel (BSP) computation is an emerging paradigm of general-purpose parallel computing. This thesis presents a systematic approach to the design and analysis of BSP algorithms. We introduce an extension of the BSP model, called BSPRAM, which reconciles shared-memory style programming with e cient exploitation of data locality. The BSPRAM model can be optimally si...

Affinity chromatography over bilirubinagarose and sulfobromophthalein (BSP)-agarose was used to isolate two proteins, with high affinities for bilirubin and BSP, respectively, from Triton X-100-solubilized rat liver plasma membranes. The protein eluted from either affinity column migrated as a single band of approximately 55,000 D on sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophores...

In the past few years, considerable evidence has been presented indicating that sulfobromophthalein sodium (BSP) is metabolized in the liver (1-6). Recently, we have demonstrated that the major pathway of BSP metabolism in man and in the rat involves conjugation of BSP with.the tripeptide glutathione (5). Similar results have been obtained by Javitt and his associates in the dog (6). Grodsky, C...

GATA4 has been reported to act as a negative regulator in osteoblast differentiation by inhibiting the Dlx5 transactivation of Runx2 via the attenuation of the binding ability of Dlx5 to the Runx2 promoter region. Here, we determine the role of GATA4 in the regulation of bone sialoprotein (Bsp) in osteoblasts. We observed that the overexpression of Runx2 or Sox9 induced the Bsp expression in os...

Described are the results of an international collaborative study to evaluate the use of whole blood samples spotted on filter-paper (BSP) for the detection of antibodies to human immunodeficiency virus type 1 (HIV-1). BSP samples were collected from 40 patients at risk for HIV-1 infection and tested blindly using commercially available HIV antibody test kits, either specifically manufactured o...

A glucomannan-type polysaccharide, named BSP, was obtained from the tubers of Bletilla striata by ultrasonic-assisted extraction, ethanol precipitation, deproteination and gel-permeation chromatography. HPLC analysis revealed that BSP contained mannose and glucose in the molar ratio of 3.5:1. Its molecular weight (Mw) was estimated to be 20 kDa. Methylation analysis, FT-IR and NMR analyses indi...

Group B streptococcus (GBS) is surrounded by a capsule. However, little is known about peptidoglycan metabolism in these bacteria. In the present study, a 65 kDa protein was isolated from the culture supernatant of GBS and N-terminally sequenced, permitting isolation of the corresponding gene, termed bsp. The bsp gene was located close to another gene, designated femH, and reverse transcription...

The process by which various anions, including bilirubin and several dyes, drugs, hormones and their metabolites, are transferred from plasma into the liver cell is poorly understood. Two hepatic cytoplasmic proteins, Y and Z, that bind various organic anions in vivo and in vitro have been postulated to be involved in this process. The concentration of Y, the major organic anion-binding protein...
