The photosphere provides an important boundary condition for prominence support. The conservation of pho-tospheric flux (sometimes called line tying) sets a serious constraint on the evolution of coronal magnetic fields. This boundary condition can only be communicated to the prominence by Alfvén and magneto-acoustic waves. As a result, the boundary condition as experienced by the prominence at...

In recent work [1], we have suggested a novel approach for fine-grained and fast prominence annotation by naı̈ve listeners. Our approach relies on annotators’ “drummed” replications of a perceived utterance, modulating their drumming velocity in accordance with the perceptual prominence of consecutive linguistic units (syllables, words). The drumming velocity is then used as a fine-grained opera...

Context. Coronal mass ejections (CMEs), as a large-scale eruptive phenomenon, often reveal some precursors in the initiation phase, e.g., X-ray brightening, filament darkening, etc, which are useful for CME modeling and space weather forecast. Aims. With the SOHO/SUMER spectroscopic observations of the 2000 September 26 event, we propose another precursor for CME eruptions, namely, long-time pr...

This paper examines the implications of “prominence” in search markets. We model prominence by supposing that the prominent firm will be sampled first by all consumers. If there are no systematic quality differences among firms, we find that the prominent firm will charge a lower price than its non-prominent rivals. The impact of making a firm prominent is that it will typically lead to higher ...

We explore the ability to perform automatic prosodic analysis in one language using models trained on another. If we are successful, we should be able to identify prosodic elements in a language for which little or no prosodically labeled training data is available, using models trained on a language for which such training data exists. Given the laborious nature of manual prosodic annotation, ...

Based on reasonable assumptions and mathematical approximations a one dimensional, analytical model for solar quiescent prominences is constructed, which is in both magnetohydrostatic and thermal equilibrium. Thermal equilibrium here is a balance among thermal conduction, radiation and wave heating. The wave heating (H) is assumed to be equal to a constant (EH ) times the product of pressure (p...

This dissertation establishes the pattern of prominence in Assamese and Assamese English. It shows for the first time that Assamese exemplifies a left – to – right trochaic system with an iterative binary rhythm. However, this rhythmic profile is disturbed by the occurrence of closed syllables deemed to be heavy. To support our intuitive judgements of prominence in Assamese with acoustic eviden...

this article is part of a much broader study of persuasive techniques in television news in iran. as a very important part of irib news irinn has been chosen for this study. if we assume that one of the most influential television news, the power of persuasion to influence the audience is very important. it seemed that choosing the highest hypothetical level of news and deconstructing it would ...

In our study we use the experimental framework of priming to manipulate our subjects‘ expectations of syllable prominence in sentences with a well-defined syntactic and phonological structure. It shows that it is possible to prime prominence patterns and that priming leads to significant differences in the judgment of syllable prominence.
