An optimal bsp for a set S of disjoint line segments in the plane is a bsp for S that produces the minimum number of cuts. We study optimal bsps for three classes of bsps, which differ in the splitting lines that can be used when partitioning a set of fragments in the recursive partitioning process: free bsps can use any splitting line, restricted bsps can only use splitting lines through pairs...

To achieve scalable parallel performance in Molecular Dynamics Simulation, we have modeled and implemented several dynamic spatial domain decomposition algorithms. The modeling is based upon Valiant’s Bulk Synchronous Parallel architecture model (BSP), which describes supersteps of computation, communication, and synchronization. We have developed prototypes that estimate the differing costs of...

Atomic force microscopy (AFM) was used to assess a new chimeric protein consisting of a fusion protein of the consensus repeat for Nephila clavipes spider dragline protein and bone sialoprotein (6mer+BSP). The elastic modulus of this protein in film form was assessed through force curves, and film surface roughness was also determined. The results showed a significant difference among the elast...

Nitrogen (N) fertilizer application is one of the causes soil acidification at tea plantations. However, effect N on characteristics plantations with different acidities remains unclear. In this study, field experiments were conducted to investigate effects nitrogen rates pH, pH buffer capacity (pHBC), exchangeable total acidity (ETA), base cations (EBCs), and cation exchange (CEC) in topsoil n...

In this paper we discuss two algorithms for performing both ways the conversion between the boundary and the interior of d-dimensional polyhedra. Both a d-polyhedron and its (d 1)-faces are represented as BSP trees. An algorithm for boundary to BSP conversion starting from a standard B-rep was given by Thibault and Naylor in [15]. In this paper we assume no structure, no ordering and even no or...

Combining the advantages of basalt fiber-reinforced polymer (BFRP) material and steel material, a novel BFRP-steel composite plate (BSP) is proposed, where a steel plate is sandwiched between two outer BFRP laminates. The main purpose of this research is to investigate the mechanical behavior of the proposed BSP under uniaxial tension and cyclic tension. Four groups of BSP specimens with four d...

Sulfobromophthalein (BSP) is normally cleared from the blood by the liver and excreted into the bile. Brauer, Krebs and Pessotti (1) originally reported that part of the pigment appearing in dog bile was chromatographically different from the injected dye. Our studies using differenlt chromatographic techniques indicate that in man the bulk of the recovered pigments (65 to 75 per cent, accordin...

Bone sialoprotein (BSP), an early marker of osteoblast differentiation, has been implicated in the nucleation of hydroxyapatite during bone formation de novo. Our studies, using the osteoblastic cell line ROS 17/2.8, have revealed that rat BSP gene expression is suppressed by 1,25-dihydroxyvitamin D3[1,25(OH)2D3], which is a powerful regulator of bone formation and resorption. To determine the ...

A quantitative comparison of the BSP and LogP models of parallel computation is developed. We concentrate on a variant of LogP that disallows the so-called stalling behavior, although issues surrounding the stalling phenomenon are also explored. Very eecient cross simulations between the two models are derived, showing their substantial equivalence for algorithmic design guided by asymptotic an...

Bone sialoprotein (BSP) is a bone-specific glycoprotein containing phosphoserine and sulphotyrosine residues and regions of contiguous glutamic acid residues. Recent studies in this laboratory have shown that BSP is capable of nucleating the bone mineral hydroxyapatite in a steady-state agarose gel system. We show here that chemical modification of carboxylate groups abolishes the nucleation ac...
