This paper reports the development of a quantitative target approximation (qTA) model for generating F(0) contours of speech. The qTA model simulates the production of tone and intonation as a process of syllable-synchronized sequential target approximation [Xu, Y. (2005).

This article describes a method of an off-line signature recognition by using parameterize Hough transform. From human nature, signatures are performed very fast by the person, and hence have a lot of straight-line segments within them. The faster that a person signs their name, the more straight lines will be present in their signature. To detect the(More)
Our current understanding of how emotions are expressed in speech is still very limited. Part of the difficulty has been the lack of understanding of the underlying mechanisms. Here we report the findings of a somewhat unconventional investigation of emotional speech. Instead of looking for direct acoustic correlates of multiple emotions, we tested a(More)
This paper reports our finding of the use of a proposed biological code – the size code in anger and joy speech. In searching for explanations for an F0 peak delay phenomenon related to angry speech that cannot be accounted for by known articulatory constraints, we hypothesized that the delay was due to the lowering of the larynx to exaggerate body size, a(More)
We tested two hypotheses to account for the reduction in coupling of anionic solute to water flow (solvent drag) in microvessels during perfusion with plasma compared with albumin. Solvent drag is determined by both hydraulic conductivity (Lp) and solute reflection coefficient (sigma). Accordingly, decreased solvent drag during plasma perfusion must be the(More)
This paper proposes two topology control algorithms – ABsolute Distance-based (ABD) and PRedictive Distance-based (PRD), which adjust the transmission range of individual nodes in a MANET to achieve good network throughput, particularly under correlated node movements as in a vehicular environment. Both algorithms attempt to maintain the number of logical(More)
This paper proposes a quantitative target approximation (qTA) model for simulating tone and intonation. Based on two theoretical models: the target approximation model (Y. Xu and Q.E. Wang, 2001) and the PENTA model (Y. Xu, 2005), the qTA model additionally incorporates several assumptions related to the underlying articulatory mechanisms, including (1)(More)
The purpose of this study was to determine whether circulating plasma protein concentration, capillary hydraulic conductivity (Lp), and overall volume status in frogs were correlated and whether these correlations varied with season. Individual vessel Lp was thus examined on a monthly basis and correlated with changes in protein content in three body(More)
The protective effects of exercise training on the diabetic-induced endothelial cell (EC) dysfunction were determined using intravital fluorescent microscopy. Male Sprague-Dawley rats were divided into three groups of control (Con), diabetes (DM), and diabetes with exercise--training (DM+Ex). Diabetes was induced by single intravenous injection of(More)
