How do speakers cope with a competing talker? This study investigated the possibility that speakers are able to retime their contributions to take advantages of temporal fluctuations in the background, reducing any adverse effects for an interlocutor. Speech was produced in quiet, competing talker, modulated noise and stationary backgrounds, with and without a communicative task. An analysis of...

In this paper we investigate weak contact relations C on a lattice L, in particular, the relation between various axioms for contact, and their connection to the algebraic structure of the lattice. Furthermore, we will study a notion of orthogonality which is motivated by a weak contact relation in an inner product space. Although this is clearly a spatial application, we will show that, in cas...

We show that quasi-alternating links arise naturally when considering surgery on a strongly invertible L-space knot (that is, a knot that yields an L-space for some Dehn surgery). In particular, we show that for many known classes of L-space knots, every sufficiently large surgery may be realized as the two-fold branched cover of a quasi-alternating link. Consequently, there is considerable ove...

This report describes a minimalistic set of methods engineered to anchor clinical events onto a temporal space. Specifically, we describe methods to extract clinical events (e.g., Problems, Treatments and Tests), temporal expressions (i.e., time, date, duration, and frequency), and temporal links (e.g., Before, After, Overlap) between events and temporal entities. These methods are developed an...

We propose to fix the boundary between the DT and CSC Level-1 Track-Finders at η = 1.04. The ramifications of this decision and the details of the implementation are discussed in this Note. The efficiency and ghost rate of the Track-Finders is also studied near this boundary.

In overlap-add synthesis of sinusoidal partials, amplitude modulation distortion can occur in the overlap region if the partial frequencies in successive frames diier. The frame-to-frame frequency changes can be accommodated by synthesizing linearly time-varying sinusoids (chirps) in adjacent frames. In this paper we present a new approach to chirp synthesis in which the distortion is eliminate...

We present four human behavioral experiments to address the question of intuitive granularities in fundamental spatial relations as they can be found in formal spatial calculi. These calculi focus on invariant characteristics under certain (especially topological) transformations. Of particular interest to this article is the concept of two spatially extended entities overlapping each other. Th...

1783 modal-falsetto register breaks and 853 falsetto-modal register breaks, produced by seven untrained adult male subjects, were recorded and analyzed with respect to jumps in fundamental frequency and sound pressure level (SPL) using a computer phonetograph. SPL and relative positions of modal and falsetto registers were the most important factors underlying the results. Whereas subor supragl...
