Managing emergency situations in large buildings and underground structures could be simplified if at any time the positions of on-site emergency crews were available. In this paper a system is proposed which combines inertial measurements of moving persons with building floor plans tagged with information on semantics to achieve a novel level of robust indoor positioning. A speech driven user ...

To elucidate mechanisms that control and execute activity-dependent synaptic plasticity, alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionate receptors (AMPA-Rs) with an electrophysiological tag were expressed in rat hippocampal neurons. Long-term potentiation (LTP) or increased activity of the calcium/calmodulin-dependent protein kinase II (CaMKII) induced delivery of tagged AMPA-Rs into syna...

Stony coral tissue loss disease (SCTLD) is affecting corals across the Western Atlantic and displays species-specific regional differences in prevalence, incidence, degree of mortality, lesion morphology. We examined two Florida sites with different temporal histories emergence; Fort Lauderdale where SCTLD endemic Lower Keys has recently emerged. Our objectives were to (1) assess potential impa...

Social Media data allows for profound analyses of user-generated content in order to predict or manage disasters and crisis situations. In this paper, we present an analysis of tweets from and about Al Za’atari, a refugee camp in Jordan close to the Syrian border. Our results are based on the analysis of location-tagged tweets by our “Avalanche” system in order to support an accurate situationa...

In a test of the hypothesis that DevR is a response regulator protein that functions in a phosphorelay signal transduction system involved in heterocyst development in Nostoc punctiforme ATCC 29133, purified affinity-tagged DevR was shown to be phosphorylated in vitro by the noncognate sensor kinase EnvZ. Site-directed mutagenesis was used to generate N. punctiforme mutants with single amino ac...

The magnitude of the effort required to complete the human genome project will require constant refinements of the tools available for the large-scale study of DNA. Such improvements must include both the development of more powerful technologies and the reformulation of the theoretical strategies that account for the changing experimental capabilities. The two technological advances described ...
