A weighted-constraint model of F0 movements/
… implementation of phonologically significant F0 (pitch) events, which is applicable across languages. Through production studies of various languages, we show that phonetic universals exist which govern phonetic realization of the phonological representations of tones. In the previous …

Interactive Development Of F0 As An Acoustic Cue For Korean Stop Contrast
… in progress, the role of fundamental frequency (F0) has been amplified for distinguishing between Korean stop contrasts with the loss of VOT differentiation in young adults’ production. The present study explores how F0 is perceptually acquired and how it phonetically operates in toddler speech …

Effects of loigomycin, F0/F1 ATP-synthase inhibitor on mitochondrial morphology and dynamics
Mitochondrial fission has recently been well-recognized as a factor involved in apoptosis although its role and the underlying mechanism remains unclear. Recently, we monitored the effects of mitochondrial respiratory inhibitors [rotenone, TTFA (2-thenoyltrifluoro-acetone), antimycin A, and …

Dynamics of F0 planning and production: contextual and rate effects on Thai tone gestures
This dissertation studies the mapping of a phonological representation to phoneticimplementation, and its consequences for theories of coarticulation and speech production, in physical space and real time through the lens of two production experiments on contextual variation in the production of …

Development, perceptual evaluation, and acoustic analysis of amplitude-based F0 control in Electrolarynx speech
… to the lack of natural fundamental frequency (F0) variation. In order to improve the quality of EL speech, the present study aimed to develop and evaluate an automatic F0 control scheme, in which F0 was modulated based on variations in the root-mean-squared (RMS) amplitude of the EL speech …

Role of F0 in speech reception in the presence of interference : simulating aspects of cochlear-implant processing
Speech is perhaps the most ecologically important acoustic stimulus to human beings, because it remains the primary means by which people interact socially. Despite many significant advances made in the development of cochlear implants, even the most successful cochlear-implant users do not hear as …

High Initial Tones and Plateaux in Spanish and Portuguese Neutral Declaratives: Consequences to the Relevance of F0, Duration and Vowel Quality as Stress Correlates
In order to verify these hypothesis a direct comparison containing neutral declaratives in both Spanish and Brazilian Portuguese was elaborated. The results show that indeed Portuguese presents a more complex intonational system than Spanish in declaratives sentence initial position. Results …

Elicitoren der Duftstoffemission von Rainfarnpflanzen
… in Rainfarnpflanzen. Vier HPLC-Fraktionen F0/2, F0/4, F0/5 und F0/6 der durch Festphasenextraktion aus dem Regurgitat von Spodoptera littoralis - Raupen erhaltenen Fraktion F0 induzieren nach Applikation an verletzte Rainfarnpflanzen die Emission von Mono- und Sesquiterpenen, die auch nach …

Acoustic Realization and Perception of English Lexical Stress by Mandarin Learners
… study focusing on the implementation of mean F0, max F0, duration, intensity, and F2 in stressed and unstressed vowels in noun-verb word pairs contrasting in stress location (e.g. object-object) was conducted. The results indicate that native English speakers use all correlates in nouns but …

Exploring lift-off dynamics in a jumping robot
… (but not at) the robot's resonant frequency f0. Two distinct jumping modes emerge: a simple jump which is optimal above f0 is achievable with a squat maneuver, and a peculiar stutter jump which is optimal below f0 is generated with a countermovement. A simple dynamical model reveals how …

Soziale Belastung während der Trächtigkeit bei Long-Evans Laborratten (Rattus norvegicus) und ihre Effekte auf die Reproduktion sowie die Physiologie, das Verhalten und die Reproduktion ihrer Nachkommen
… auf die Reproduktion der Parentalgeneration (F0-Weibchen) selbst, sowie auf die Reproduktion, das Verhalten und die Physiologie ihrer pränatal gestressten Nachkommen (F1-Generation) auswirkt (pränataler Stress). Hierbei galt das Hauptaugenmerk der Untersuchung dem Einfluss pränataler Belastung …

Speech rhythm: the language-specific integration of pitch and duration
… investigated the interaction of duration and f0 as perceptual cues to prosody in languages with different prosodic structures – Swiss German, Swiss French, and French (i.e. from France). The first experiment demonstrated that a dynamic f0 increases perceived syllable duration in contextually …

Exploring the Use of Supervised Machine Learning Algorithms to Classify Simulated Balance Deficits
… 1/2”, and 1”. These thicknesses were labeled as F0, F1, F2, F3, F4, respectively. The Center of Pressure (COP) was calculated and 30 linear and non-linear measures were calculated to characterize this time series. These measures were then used as the input features for 23 supervised machine …

Improving individual identification of wolves (Canis lupus) using the fundamental frequency and amplitude of their howls: a new survey method
… from variations in the fundamental frequency (F0) of their vocalizations. Other characteristics of vocalization which encode individuality, such as amplitude, are less frequently used because of problems with background noise and recording fidelity over distance. In this thesis, I investigate …

Counting supercuspidal representations of p-adic groups
… representations of the unitary groups U(1; 1)(F~F0) and U(2; 1)(F~F0) by looking at their characteristic polynomials and then compute the number of all these representations according to their level.

Phonetic and Phonological Evidence for Intermediate Phrasing in Spanish Intonation
… boundary) combine to determine utterance-final F0 movement. The fact that both T- and T% appear in intonation-phrase final position in Spanish now calls for a reanalysis of basic F0 contours in the language within the AM framework.

Supralaryngeal Articulator Movements and Laryngeal Control in Mandarin Chinese Tonal Production
… The influence of vocal tract configuration on F0 of vowels was noted for all participants. However, not all participants demonstrated the influence of F0 control on vowel quality. Similarly, articulatory compensation was not noted for all participants for tongue height adjustments when the jaw …

Development of ice-bonded ballast in sub-freezing temperatures and its effect on maintenance operations during a winter rail break
… temperatures, longitudinal track resistance (f0) to restrain the track system has been quantified by crosstie-type and ballast condition (e.g., consolidated or disturbed). Sub-freezing temperatures produce the largest differentials between the rail temperature and RNT (rail neutral …

Microtremor recordings in Northern Mississippi: Evaluating site effect and correlating with wave climate
… is applied to find the predominant frequency (f0) and roughly estimate amplification factor as HVSR value at f0 (HVSR@f0). Within Northern Mississippi area, the f0 is tightly correlated with unconsolidated sediments thickness (UST) and average shear wave velocity (Vs) are also estimated. Within …
