On Permissibility of Covariogram Models with Applications to Analyzing Human Brain Functional Data
Many clinical and research studies, based on functional imaging, require accurate, fast and robust tools for denoising data and determining the statistically important portion of the data content of the image.
We propose a new method, Sub-Volume Thresholding (SVT), for statistical analysis of stereotaxic human brain functional data. The goal is to identify the statistically significant metabolic changes in activation (stimulus) versus baseline (rest) functional brain scans. The SVT technique allows incorporating of prior anatomical/functional information about the study into the model through selection of a proper structural partitioning of the domain of the image.
In the process of developing our model we naturally encounter a class of covariogram functions. These are shown to be permissible, which implies that a legitimate probability distribution underlines our model.
We will discuss two examples. The first one involves left/right hand motor studies, and the second one investigates the effects of an anti-depressant drug treatment. Finally, we compare our results with other commonly used statistical techniques.

Multi-Disciplinary Research in USAF Wright Laboratory

Multi-disciplinary technology development becomes critical in supporting the New World Vistas vision of air and space power for the 21st Century. This enabling technology maturation requires validation and integration of fluid dynamics, structural mechanics, flight control, chemical physics, electromagnetics, and high performance computing to achieve a seamless simulation capability. Scientific challenge, research opportunity, and progress will be delineated.
