SMART, Solid Modeling Aerospace Research Tool, isthe Vehicle AnalysisBranch of NASA Langley Research Center's computer-aided design tool used in aerospace vehicledesign. Modeling of structuralcomponents using SMART includes the representationof the transverseor cross-wiseelements of a vehicle'sfuselage,ringframes and bulkheads. Ringframes are placed along a vehicle'sfuselage to provide structur...

OBJECTIVE There are two theories (by Horowitz and by Foa) which attempt at explaining the process of posttraumatic stress disorder (PTSD) development by information dissonance. The purpose of the present study was to verify these theories via cross-sectional and longitudinal studies. MATERIALS AND METHODS The study based on a cross-sectional design was performed on a representative group of P...

This paper presents a two-step, semi-automated method for reconstructing a three-dimensional (3D) shape of the prostate from a 3D transrectal ultrasound (TRUS) image. While the method has been developed for prostate ultrasound imaging, it can potentially be applicable to any other organ of the body and other imaging modalities. The proposed method takes as input a 3D TRUS image and generates a ...

How reliable are reconstructions of body mass and joint function based on articular surface areas? While the dynamic relationship between mechanical loading and cross-sectional geometry in long bones is well-established, the effect of loading on the subchondral articular surface area of epiphyses (hereafter, articular surface area, or ASA) has not been experimentally tested. The degree to which...

We present a framework for shape alignment that generalizes several existing methods. We assume that the shape is a closed genus zero surface. Our framework requires a diffeomorphic surface mapping to the 2-sphere which preserves rotation. Our similarity measure is a global spherical cross-correlation function of surface-intrinsic scalar attributes, weighted by the cross-correlation of the para...

There are many studies that compare the accuracy of multislice (MSCT) and cone beam (CBCT) computed tomography for evaluations in the maxillofacial region. However, further studies comparing both acquisition techniques for the evaluation of simulated mandibular bone lesions are needed. The aim of this study was to compare the accuracy of MSCT and CBCT in the diagnosis of simulated mandibular bo...

This study describes a human foot bone assemblage from prehistoric Mangaia, Cook Islands in the context of diaphyseal cross-sectional strength measures. We use this sample to test the hypothesis that habitually unshod individuals who walk over rugged terrain will have stronger foot bones than a sample of habitually shod industrialized people. Specifically, we examine whether the Mangaian sample...

Vegetarianism, which is increasingly widespread in Western societies, underpinned by various motivations (ethical, environmental, health concerns …) and the question of its association with eating disorders continues to divide literature. This cross-sectional study aimed explore compare motives/attitudes bodily preoccupations vegetarian omnivorous participants from general population. Forty-nin...
