The collimation of relativistic jets launched from the vicinity supermassive black holes (SMBHs) at centers active galactic nuclei (AGN) is one key questions to understand nature AGN jets. However, little known about detailed jet structure for like quasars since very high angular resolutions are required resolve these objects. We present long baseline interferometry (VLBI) observations archetyp...

Pim kinases are Ser/Thr kinases with multiple substrates that affect survival pathways. These proteins are overexpressed in acute myeloid leukemia (AML) blasts and we hypothesized that Pim kinase inhibition would affect AML cell survival. Imidazo[1,2-b]pyridazine compound, SGI1776 inhibits Pim-1, Pim-2 and Pim-3, and was evaluated in AML-cell line, -xenograft model, and -primary blasts. Treatme...

In this work we discuss hardware and software aspects of parallel 3-D wavelet/subband decomposition on shared memory MIMD computers. Experimental results are conducted on a SGI POWERChal-lenge GR.

In order to understand star formation it is important to understand the dynamics of atomic and molecular clouds in the interstellar medium (ISM). Nonlinear hydrodynamic flows are a key component to the ISM. One route by which nonlinear flows arise is the onset and evolution of interfacial instabilities. Interfacial instabilities act to modify the interface between gas components at different de...

The current dominant concept for the control of saccadic eye movements by the basal ganglia is that release from tonic GABAergic inhibition by the substantia nigra pars reticulata (SNr) triggers burst firings of intermediate gray layer (SGI) neurons in the superior colliculus (SC) to allow saccade initiation. This hypothesis is based on the assumption that SNr cells inhibit excitatory projectio...

This paper describes Tulip, a parallel run-time system used by the pC++ parallel programming language. Tulip has been implemented on a variety of scalable, MPP computers including the IBM SP2, Intel Paragon, HP/Convex SPP, Meiko CS2, SGI Power Challenge, and Cray T3D. Tulip differs from other data-parallel RTS implementations; it is designed to support the operations from object-parallel progra...
