Forensic voice comparison (FVC) systems have often involved manual annotation of usable phonetic units, requiring substantial human labor. Recent research has shown the efficacy of automatic methods in FVC, and this paper investigates automatic phonetic segmentation in FVC systems. Nasals and vowels were found to contribute the most in terms of improvements(More)
Automatic forensic voice comparison (FVC) studies have often employed Gaussian Mixture Model - Universal Background Model (GMM-UBM) modeling based on mean-only maximum a posteriori (MAP) adaptation or full MAP adaptation with little consideration of other variants of MAP adapted configurations. Our study indicates that an FVC system improvement in(More)
Polylactide-glycolide (PLGA) nanoparticles have been developed as pulmonary drug delivery carriers. To investigate their behavior, small- (d50 = 74 nm) and large-sized (d50 = 250 nm) FITC-conjugated PLGA nanoparticles were intratracheally administered to rats and were traced for 5, 30 and 60 minutes and 24 hours after administration (HAT).(More)
Our reported data on the cortical inhibitory actions of prostaglandin F2alpha (PGF2alpha) and the diversity of data in the literature on cerebral PG actions are examined here in the light of intracellular recording which provides the requisite membrane data for the first time. Thus, 1) intracellular recording from the cat cerebral cortex is obtained for the(More)
