Singular Isotropic Cosmologies and Bel - Robinson Energy 1
We consider the problem of the nature and possible types of spacetime singularities that can form during the evolution of FRW universes in general relativity. We show that by using, in addition to the Hubble expansion rate and the scale factor, the Bel-Robinson energy of these universes we can consistently distinguish between the possible different types of singularities and arrive at a complet...
متن کاملNCU - IISR System for BioCreative BEL Task 1
Biological networks are important for biologists to represent and understand biological systems. These networks can be represented by languages such as BEL and SBML. Automatically extracting these descriptions and representing them in the biological system languages can improve the efficiency of constructing these networks. In this paper, we expand our previous Named Entity Recognition and Norm...
متن کاملProperties of Bel currents
The Bel tensor is divergence-free in some important cases leading to the existence of conserved currents associated to Killing vectors analogously to those of the energy-momentum tensor. When the divergence of the Bel tensor does not vanish one can study the interchange of some quantities between the gravitational and other fields obtaining mixed total conserved currents. Nevertheless, the Bel ...
متن کاملBEL: Bagging for Entity Linking
With recent advances in the areas of knowledge engineering and information extraction, the task of linking textual mentions of named entities to corresponding ones in a knowledge base has received much attention. The rich, structured information in state-of-the-art knowledge bases can be leveraged to facilitate this task. Although recent approaches achieve satisfactory accuracy results, they ty...
متن کاملThe Bayesian Description Logic BEL
We introduce the probabilistic Description Logic BEL. In BEL, axioms are required to hold only in an associated context. The probabilistic component of the logic is given by a Bayesian network that describes the joint probability distribution of the contexts. We study the main reasoning problems in this logic; in particular, we (i) prove that deciding positive and almost-sure entailments is not...
