The blue supergiant Sher 25 and its intriguing hourglass nebula
The blue supergiant Sher 25 is surrounded by an asymmetric, hourglass-shaped circumstellar nebula. Its structure and dynamics have been studied previously through high-resolution imaging and spectroscopy, and it appears dynamically similar to the ring structure around SN1987A. Here we present long-slit spectroscopy of the circumstellar nebula around Sher 25, and of the background nebula of the ...
متن کاملScalable highly expressive reasoner (SHER)
In this paper, we describe SHER (Scalable Highly Expressive Reasoner), a breakthrough technology that provides semantic querying of large relational datasets using OWL ontologies. SHER relies on a unique algorithm based on ontology summarization and combines a traditional in-memory description logic reasoner with a database backed RDF Store to scale reasoning to very large Aboxes. In our latest...
متن کاملNorharman exacerbates 6-hydroxydopamine-induced Parkinson’s disease but cannot establish it alone
Introduction: β-carbolines (BCs) are heterocyclic indole alkaloids found in human body, grilled meat, alcoholic beverages and tobacco smoke. Based on the present reports, there are controversies about the role of these compounds in the pathophysiology of Parkinson' disease (PD).

An intelligent software agents use information to organize and filter data to meet the user's needs. DAML+OIL and Web Ontology Language OWL are the current environments to create Ontology over RDF and ...
متن کاملGila Sher Truth, Logical Structure, and Compositionality
In this paper I examine a cluster of concepts relevant to the methodology of truth theories: ‘informative definition’, ‘recursive method’, ‘semantic structure’, ‘logical form’, ‘compositionality’, etc. The interrelations between these concepts, I will try to show, are more intricate and multi-dimensional than commonly assumed. 1. TRUTH AND RECURSION In his 1933 paper, “The Concept of Truth in F...
