In this paper we discuss an algorithm to perform the conversion from the interior to the boundary of d-dimensional polyhedra, where both the d-polyhedron and its (d 1) boundary faces are represented as BSP trees. This approach allows also to compute the BSP tree of the set intersection between any hyperplane in Ed and the BSP representation of a d-polyhedron. If such section hyperplane is the a...

Bone sialoprotein (BSP), an early marker of osteoblast differentiation, has been implicated in the nucleation of hydroxyapatite during de novo bone formation. Low-power laser irradiation has a stimulating effect on cells and tissues. Although the carbon dioxide (CO(2)) laser is a hard surgical laser, we have attempted to use it at low energy density to achieve biological alterations. To investi...

The authors report preliminary results of Brief Supportive Psychotherapy (BSP) in the Beth Israel Brief Psychotherapy Program for a sample with primarily Cluster C Axis II disorders. This study compares 24 patients treated with BSP with 25 patients treated with Short-Term Dynamic Psychotherapy (STDP). STDP was chosen because its confrontational methods contrast dramatically to BSP, which emphas...

Manager-Vorsorgen Check-up...

BACKGROUND Concerns that bedside presentation (BsP) rounds could make patients uncomfortable led many residency programs to move daily rounds outside the patients' room (OsPR). We performed a prospective quasi-experimental controlled study measuring the effect of these two approaches on patient satisfaction. METHODS Patient satisfaction was measured using the Picker questionnaire (PiQ). Resul...

The small bile ducts in the liver of a number of species are enmeshed by a vascular plexus, supplied largely by the hepatic artery (1-3). This peribiliary arterial plexus has been considered by some as evidence that the bile duct epithelia might play an important and active role in the secretion of bile, possibly even to the exclusion of the parenchymal cells (4, 5). In support of this view, it...

ion for algorithm design and programming, while LogP provides better control of machine resources. Comparisons and evaluations between the two models have been made in [29,62,104]. In [29], a variant of LogP that disallows the so-called stalling behavior is considered. The authors create cross simulations between the two models showing their equivalence in algorithmic design when using asymptot...

The Paderborn University BSP (PUB) library is a parallel C library based on the BSP model. The basic library supports buffered and unbuffered asynchronous communication between any pair of processors, and a mechanism for synchronizing the processors in a barrier style. In addition, it provides routines for collective communication on arbitrary subsets of processors, partition operations, and a ...

The rat osteosarcoma cell line (UMR 106-01) synthesizes and secretes relatively large amounts of a sulfated glycoprotein into its culture medium (approximately 240 ng/10(6) cells/day). This glycoprotein was purified, and amino-terminal sequence analysis identified it as bone sialoprotein (BSP). [35S]Sulfate, [3H]glucosamine, and [3H]tyrosine were used as metabolic precursors to label the BSP. S...

OBJECTIVES To investigate the expression and prognostic value of bone sialoprotein (BSP) in glioma patients. METHODS We determined the expression of BSP using real-time RT-PCR and immunohistochemistry in tissue microarrays containing 15 normal brain and 270 glioma samples. Cumulative survival was calculated by the Kaplan-Meier method and analyzed by the log-rank test. Univariate and multivari...
