Semantic Search through the Neuroscience Information Framework

submitted by: jgrethe

This video tutorial explores advanced search through the Neuroscience Information Framework, a dynamic inventory of Web-based neuroscience resources (i.e. data, materials, and tools). In the tutorial, semantic search is explored and how one can use the NIF ontologies to refine, expand, and customize the search/discovery process.

The Environment Ontology: Linking Environmental Data

submitted by: dougramsey
Norman Morrison, University of Manchester Every biological specimen that is collected or sampled — whether for a museum collection, for epidemiological studies, for population studies, for ecological research, for research into evolution, biodiversity or sustainability, indeed any biological research — comes from a particular habitat where particular physical conditions prevail. How ever, at present there is no accepted semantic standard for describing the environment from which these...

Efficient Metagenomics Data Processing: Pitfalls and Solutions

submitted by: dougramsey
Nikos Kyrpides, Joint Genome Institute Co-authors: Kostas Mavrommatis, Natalia Ivanova Metagenomics has emerged as a powerful tool for exploration of the functional capabilities of microbial communities regardless of the ability of their members to grow in pure culture. However, little is known for the efficacy of the methods used to process these datasets. Further more, sequencing of environmental genomic DNA usually results in large, highly fragmented datasets representing a significant...

Z. Khachaturian, PhD. - New approaches to the therapy of Alzheimer’s disease (AD) are discussed in video interviews of this series. According to Z. Khachaturian (Potomac, MD) substantial progress has been made during the last 10 years in our understanding of pathogenesis of Alzheimer’s disease as well as in the discovery of biomarkers and therapeutic approaches. In addition to cholinergic drugs, inhibitors of plaque formation have been discovered, but the currently available...

A Pseudo-Boolean Programming Approach for Computing the Breakpoint Distance Between Two Genomes with Duplicate Genes

submitted by: dougramsey

Annelyse Thevenin argues that the best approach to calculating breakpoint distance between two genomes with duplicate genes is by using Pseudo-Boolean Programming.
