Three Music Theater vocal qualities ("chesty belt," "twangy belt," and "legit") were investigated in female singers at their overlap range, between F#4-D5 (~370-600 Hz). Six experienced Music Theater singers performed each quality on two different vowels ([e], [ɔ]). Audio and electroglottographic (EGG) signals were recorded as well as the vocal tract impedance. In chesty belt and twangy belt, s...

We aimed to identify clinical factors associated with recurrent infective endocarditis (IE) episodes. The characteristics of 2816 consecutive patients definite IE (January 2008–2018) were compared according the development a second episode IE. A total 2152 out 2282 (94.3%) patients, who discharged alive and followed-up for at least first year, presented single IE, whereas 130 (5.7%) recurrence;...

This study investigated non-contrastive voice qualities in Northern Vietnamese tones with a focus on huyền and hỏi. The analysis measured the relative amplitude of the first and second harmonics (H1-H2) and of the first harmonic and first formant (H1-A1) in a sample of native speaker speech. While the results are consistent with reports of multiple voice qualities for huyền and hỏi, huyền appea...

BACKGROUND This study was conducted to determine whether the paranasal extension of a primary non-Hodgkin's lymphoma (NHL) of the nasal cavity has any deleterious effect on patient outcome. METHODS One hundred and seventy-five patients with previously untreated nasal NHL were reviewed. There were 2 with low grade, 107 with intermediate grade, 17 with high grade, and 49 with unclassifiable lym...

Although many studies of family constellations exist, only recently have investigators begun to examine the qualities of sibling relationships. The purpose of the present investigation was to develop a systematic framework for describing and assessing such relationship qualities. In the first study, upper elementary school children were interviewed about their perceptions of the qualities of th...

Idiopathic erythrocytosis (IE) is characterized by an increase of red blood cell mass without an identified cause. Its diagnosis is based on the exclusion of polycythemia vera (PV), secondary acquired polycythemias and various congenital primary and secondary polycythemias. The frequency of IE has been estimated to be 1.1 per 1000 subjects, which is higher than that observed in PV. Heterogeneou...

In this paper, we describe our approach taken in the MSM2013 IE Challenge, which was aimed at concept extraction from microposts. The goal of the approach was to combine several existing NER tools which use different classification methods and benefit from their combination. Several NER tools have been chosen and individually evaluated on the challenge training set. We observed that some of the...
