The logical optimized abstract syntax tree (AST) for the DFE query plan is printed with information about the operator types that were considered while planning and the associated best- and worst-case costs to
It is important to be able to convert scientific data to a graph in order to visually represent the data and identify trends. The identification of these trends is very crucial to the development of a scientific conclusion based on evidence....

Given the (informative) description of reifications (resources of typerdf:Statement): The subject of areificationis intended to denote a concrete realization of an RDF triple, such as a document in a surface syntax, rather than a triple considered as an abstract object. This supports use cases...
Abstract The characterization of topology is crucial in understanding network evolution and behavior. This paper presents an innovative approach, the GHuST framework to describe complex-network topology from graphlet decomposition. This new framework exploits the local information provided by graphlets to ...
Abstract We demonstrate a very general mathematical and physical expression of the rotation speed at the end of the galaxy (far from the vast majority of the galaxy’s baryonic mass) obtained from General Relativity without non-baryonic matter. We show the excellent agreement with measurements ...
