Many of the existing cloud tagging systems are unable to cope with the syntactic and semantic tag variations during user search and browse activities. As a solution to this problem, we propose the Semantic Tag Clustering Search, a framework which is able to cope with these needs. The framework consists of two parts: removing syntactic variations and creating semantic clusters. For removing syntactic...
The Region Connection Calculus based on 8 relations (RCC8) is one of several extensively researched methods to use for qualitative spatial representation and reasoning. We discuss several issues arising when representing RCC8 in OWL DL, a decidable fragment of OWL. There is no direct encoding of such a calculus in OWL DL, as the language lacks required features such as role reflexivity, role Boolean...
We examined the occurrence of functional interactions between CB1 cannabinoid and μ opioid receptors in the core of rat nucleus accumbens (NAc core). To that end, receptor-mediated inhibition of depolarization (4-aminopyridine)-induced [ 3 H]glutamate release and glutamate (NMDA) receptor-stimulated [ 14 C]acetylcholine (ACh) and [ 3 H]GABA release was studied in superfused...
Abstract In the present study, the reactivity of striatal dopamine and dopamine-sensitive neurons in superfused striatal slices of ethanol-experienced rats was compared to that of ethanol-naive rats, 3 weeks after oral ethanol self-administration. During the acquisition phase (17 days), rats were offered increasing concentrations of ethanol (from 2 to 10%, 24h per day) on an alternate-day schedule...
