Introduction. The aim of this study was to determine the accuracy of linear measurements in dry human skulls in ideal position and different deviated positions of the skull. Methods. 6 dry human skulls were included in the study. Opaque markers were attached to alveolar bone. Buccolingual and mesiodistal distances and heights were measured in 5 different regions of either jaws using a digital c...

In this study we tested 24and 36-week-old infants’ ability to discriminate normal speech from speech with a positive or negative spectral tilt: 9dB/octave in Experiment 1, and 6dB/octave in Experiment 2. In Experiment 1 both age groups could discriminate speech with no spectral tilt from speech with positive and negative 9dB/octave emphasis. In Experiment 2 the 36-week-olds could only discrimin...

Across a variety of tasks, adults respond differently to syllables with multiple stress cues than to syllables with only one cue to stress. This series of experiments was designed to explore how infants and adults use partial stress as a cue to word boundaries. In the first experiment, 9-month-old infants treated syllables with only one cue to stress (spectral tilt) as a strong cue to word boun...

This paper presents an analysis of affective sentences spoken by a single speaker. The corpus was analyzed in terms of different acoustic and prosodic features, including features derived from the decomposition of pitch contours into phrase and accent curves. It was found that sentences spoken with a sad affect were most easily distinguishable from other affects as they were characterized by a ...

BACKGROUND The management of distal radial fractures is guided by the interpretation of radiographic findings. The aim of this investigation was to determine the intra- and inter-observer reliability of eight traditionally reported anatomic radiographic parameters in adults with an acute distal radius fracture. METHODS Five observers participated. All were routinely involved in making treatme...

Spectral approximations on the triangle by orthogonal polynomials are studied in this paper. Optimal error estimates in weighted semi-norms for both the L2− and H1 0−orthogonal polynomial projections are established by using the generalized Koornwinder polynomials and the properties of the Sturm-Liouville operator on the triangle. These results are then applied to derive error estimates for the...

We study an elliptic boundary value problem in a semi-infinite, straight waveguide containing a periodic material distribution. The spectral parameter is taken to lie in a spectral band of the corresponding full-space periodic operator. In contrast to the situation with constant coefficients, it is not obvious how to define the “outgoing” solution of the problem. In order to define the outgoing...

INTRODUCTION Most computer-assisted navigation systems used in total hip arthroplasty (THA) reference the anterior pelvic plane, which connects the anterior superior iliac spines and the pubic symphysis. The pelvic tilt is defined as the angle between this anterior pelvic plane (APP) and a vertical line in the standing position. Important interindividual variations of this angle have been repor...
