Trichome patterning in Arabidopsis serves as a model system to study how single cells are selected within a field of initially equivalent cells. Current models explain this pattern by an activator-inhibitor feedback loop. Here, we report that also a newly discovered mechanism is involved by which patterning is governed by the removal of the trichome-promoting factor TRANSPARENT TESTA GLABRA1 (T...

This paper deals with a so-far unnoticed phenomenon in prosodic phonology, which we dub prosodic smothering. Prosodic smothering arises when the prosodic status of a clitic or affix varies with the presence or absence of some outer morpheme. We first illustrate prosodic smothering with novel data from two genetically unrelated languages, Macedonian (Slavic) and Kaqchikel (Mayan). We then provid...

This study examines the prosodic marking of topic constructions in Mandarin Chinese. The findings suggest that, even though on the surface there are prosodic markings that differentiate topics from comments, the difference is the product of the prosodic phrasing, coupled with the declination and final lowering, in that a topic construction is usually decomposed into to two prosodic constituents...

As the basic prosodic unit, the prosodic word influences the naturalness and the intelligibility greatly. Although the research shows that the lexicon word are greatly different from the prosodic word, the lexicon word still provides the important cues for the prosodic word forming. The rhythm constraint is another important factor for the prosodic word prediction. Some lexicon word length patt...

In our paper we examine the usage of prosodic features in speech recognition, with a special attention payed to agglutinating and fixed stress languages. The used prosodic features, acoustic-prosodic preprocessing, and segmentation in terms of prosodic units are presented in details. We use the expression ”prosodic unit” in order to make a difference from prosodic phrases, which are longer. We ...

This work focuses on the relationship between prosodic and syntactic domains in order to investigate whether there is a preferred syntactic domain of tonal units and whether there is a preferred prosodic domain of syntactic constituents. Two independent analyses of phonetic prosodic boundaries of syntactic constituents and of syntactic structure of prosodic constituents in Italian spontaneous d...

Recently, speaker verification systems using different kinds of prosodic features have been proposed. Although it has been shown that most of these speaker verification systems can improve system performance using score-level fusion with stateof-the-art cepstral-based systems, a systematic comparison of the prosodic modelling algorithms used in these prosodic systems has not yet been performed....
