A target Approximation Intonation Model for Yorùbá TTS
(ISCA, 2014)A complete intonation model based on quantitative target approximation is described for Yorùbá text-to-speech (TTS) synthesis. This model is evaluated analytically and perceptually and compared to a fundamental frequency ... -
Target of opportunity observations of blazars with H.E.S.S.
(PoS, 2017)The very-high-energy (VHE, E>100 GeV) extragalactic sky is dominated by blazars, a class of active galactic nuclei which show rapid variability at all wavelengths. Target of Opportunity (ToO) observations triggered by ... -
Target of opportunity observations of blazars with H.E.S.S.
(AIP, 2017)The very high energy (VHE, E > 100 GeV) sky is dominated by blazars, radio-loud active galactic nuclei whose relativistic jet is closely aligned with the line of sight. Blazars are characterized by rapid variability at all ... -
Targeted proteomic response to coffee consumption
(Springer, 2020)Purpose Coffee is widely consumed and implicated in numerous health outcomes but the mechanisms by which coffee contributes to health is unclear. The purpose of this study was to test the effect of coffee drinking on ... -
Task-specific strength increases after lower-limb compound resistance training occurred in the absence of corticospinal changes in vastus lateralis
(Wiley, 2020)Neural adaptations subserving strength increases have been shown to be task-specific, but responses and adaptation to lower-limb compound exercises such as the squat are commonly assessed in a single-limb isometric task. ... -
Taxonomic revision and morphological cladistics analysis of the diatom genus Anorthoneis (Cocconeidaceae), with description of Anorthoneis arthus-bertrandii sp. nov.
(Magnolia Press, 2018)We present here an ultrastructure-based revision of the diatom genus Anorthoneis using both light (LM) and electron microscopy (SEM). The original slides and type material of all known Anorthoneis species were analysed and ... -
