results the mean age of patients was 16.7 ± 2.5 years. there was no statistically significant difference between the two groups regarding gender, age, curve before surgery, and percentage of flexibility. the mean curvature was 70 ± 20.7 in the hr and 64.81 ± 19.4 in the cd group before surgery (p = 0.09); and the mean curvature was 40 ± 16.3 and 26.58 ± 15.37 in hr and cd groups respectively af...

This paper presents a number of different sonification approaches that aim to communicate geometrical data, specifically curve shape and curvature information, of virtual 3-D objects. The system described here is part of a multi-modal augmented reality environment in which users interact with virtual models through the modalities vision, hearing and touch. An experiment designed to assess the p...

Cross-modal information retrieval based on subjective aims to enable flexible media services, such as allowing users specify, for example, an image search audio clips. The resulting clips should have impression similar the specified image. Existing methods focus building cross-media cross-modal relationships using objective (such standard caption). However, a relation can be built only between ...

In this paper, following a two-stage methodology, the differential quadrature element (DQE) model of a three-story frame structure is updated for the vibration analysis. In the first stage, the mass and stiffness matrices are updated using the experimental natural frequencies. Then, having the updated mass and stiffness matrices, the structural damping matrix is updated to minimize the error be...

The present experiments investigated the role of the prelimbic-infralimbic areas in behavioral flexibility using a place-response learning paradigm. All rats received a bilateral cannula implant aimed at the prelimbic-infralimbic areas. To examine the role of the prelimbic-infralimbic areas in shifting strategies, rats were tested on a place and a response discrimination in a cross-maze. Some r...

One of the most promising fields of finite element model updating involves using data obtained from the modal response of a structure to update a finite element model. The University of Central Florida (UCF) has constructed a scale model of a two span bridge. Using an impact hammer and accelerometers mounted on the structure, the first 17 natural frequencies and mode shapes were identified. Usi...

Using a combination of X-ray scattering, fluorescence correlation spectroscopy, coarse-grained molecular dynamics (MD) simulations and potential of mean force calculations, we have explored the membrane remodeling effects of monomeric α-synuclein (αS). Our initial findings from multiple approaches are that αS (1) causes a significant thinning of the bilayer and (2) stabilizes positive mean curv...
