Ontologies have been used as vehicles to assign semantics to data in several domains, since they represent a conceptualization about the domain of interest and establish a common vocabulary to be shared. For properly addressing the domain of interest and serving as a means to attribute meaning to data, ontology should provide a correct understanding of the domain conceptualization. This paper p...

This paper presents a framework for developing a new graphics domain, called GRO, in Ptolemy II [1]. GRO is an OpenGL-based implementation that imports utilities, semantic and functionalities of OpenGL. The specification provides users to fully utilize the potential in the communication between the rendering engine and the computation in the model. This bottom-up design approach allows develope...

We have used the interaction trap, a yeast two-hybrid system, to identify proteins interacting with hairy, a basic-helix-loop-helix (bHLH) protein that represses transcription during Drosophila embryonic segmentation. We find that the groucho (gro) protein binds specifically to hairy and also to hairy-related bHLH proteins encoded by deadpan and the Enhancer of split complex. The C-terminal WRP...

We present broad-band (2 keV to 2 MeV) x-ray spectra of GRO J1655{40, a luminous X-ray transient and occasional source of relativistic radio jets, obtained with the Rossi X-Ray Timing Explorer (RXTE) and the Oriented Scintillation Spectrometer Experiment (OSSE). In one observation, the luminosity is found to be 18% of the Eddington limit, which is one of the highest luminosities ever observed f...

A full length cDNA clone of the platelet-derived growth factor-inducible KC gene has been isolated, sequenced, and expressed in COS cells. Both sequence analysis and expression studies indicate that KC encodes a secretory protein. Sequence analysis shows that, furthermore, the protein encoded by KC belongs to a growing superfamily of inducible proteins with a common ancestral linkage to the pla...
