Noradrenergic deficits have been described in the hippocampus and the frontal cortex of Alzheimer's disease brains, which are secondary to locus coeruleus degeneration. Locus coeruleus is the brain stem nucleus responsible for synthesis of noradrenaline and from where all noradrenergic neurons project. In addition, it has been suggested that noradrenaline(More)
Managing and analyzing information remains an enduring and essential challenge for intelligence professionals. Link analysis tools are beginning to be adopted in the intelligence community as part of the community's analysis toolset. However, since a wide variety of types of analyses is possible, even within just the link analysis field, no one tool is(More)
To meet the intelligence community's need for link analysis tools that work together, researchers are currently investigating ways of building workflows of these tools using an intelligent system architecture. A key challenge in building a dynamic link analysis workflow environment is representing the behavior of the individual link analysis algorithms(More)
A simple single-stage approach, based on the hydrothermal technique, has been introduced to synthesize reduced graphene oxide/titanium dioxide nanocomposites. The titanium dioxide nanoparticles are formed at the same time as the graphene oxide is reduced to graphene. The triethanolamine used in the process has two roles. It acts as a reducing agent for the(More)
Given the rapidly changing skills needs of 'post-industrial economies', lifelong learning forms an integral part of government policy within the UK and abroad. However, like the UK, most economies are faced with the problem of how to reach those sections of the community that have traditionally not embraced learning and educational opportunities. In this(More)
This symposium brought together a number of researchers who are concerned with performance issues that robots face that depend, in some way, on sound. Many commercially marketed robotic platforms, as well as others that are moving from the laboratory into specialized public settings, already have rudimentary speech communication interfaces, and some are(More)
