چکیده
In this report we present a set of software components for distributed relation-based computations (SCDRC).We explain how SCDRC can be used to structure parallel computations in a single-program multiple-data computational environment. First, we introduce relation-based algorithms and relation-based computations as generic patterns in scientific computing. We then discuss the problems that have to be solved to parallelize such patterns and propose a high-level formalism for specifying these problems. This formalism is then applied to derive parallel distributed relation-based computations. These are implemented in the C++ library SCDRC. We present language independent elements of SCDRC and discuss C++ specific aspects of its design and architecture. Finally, we discuss how to use SCDRC in a simple application and provide preliminary performance figures. 4 N. BOTTA, C. IONESCU, C. LINSTEAD, R. KLEIN

Isoform-selective phosphoinositide 3'-kinase inhibitors inhibit CXCR4 signaling and overcome stromal cell-mediated drug resistance in chronic lymphocytic leukemia: a novel therapeutic approach.
Phosphoinositide 3-kinases (PI3Ks) are among the most frequently activated signaling pathways in cancer. In chronic lymphocytic leukemia (CLL), signals from the microenvironment are critical for expansion of the malignant B cells, and cause constitutive activation of PI3Ks. CXCR4 is a key receptor for CLL cell migration and adhesion to marrow stromal cells (MSCs). Because of the importance of C...

متن کاملRegulation of phosphatidylinositol 4-kinase by the protein activator PIK-A49. Activation requires phosphorylation of PIK-A49.
PIK-A49 is a 49-kDa soluble protein that was isolated as an activator of the plasma membrane phosphatidylinositol (PI) 4-kinase from carrot cells (Yang, W., Burkhart, W., Cavallius, J., Merrick, W. C., and Boss, W. F. (1993) J. Biol. Chem. 268, 392-398). PIK-A49 is a multifunctional protein that binds and bundles F-actin and has translational elongation factor-1 alpha activity. In this paper, w...
متن کاملA randomized evaluation of a computer-based nursing documentation system.
A two-month randomized, controlled trial based on 60 patients has been performed on a ward of the Department of Psychiatry at Heidelberg University Medical Center, Germany, to investigate the influence of computer-based nursing documentation on time investment for documentation, quality of documentation and user acceptance. Time measurements, questionnaires, documentation analysis and interview...
متن کاملA dual phosphoinositide-3-kinase alpha/mTOR inhibitor cooperates with blockade of epidermal growth factor receptor in PTEN-mutant glioma.
We have shown previously that blockade of epidermal growth factor receptor (EGFR) cooperates with a pan-selective inhibitor of phosphoinositide-3-kinase (PI3K) in EGFR-driven glioma. In this communication, we tested EGFR-driven glioma differing in PTEN status, treating with the EGFR inhibitor erlotinib and a novel dual inhibitor of PI3Kalpha and mTOR (PI-103). Erlotinib blocked proliferation on...
