Histochemical Demonstration Of Endothelial Superoxide And Hydrogen Peroxide Generation In Ischemic And Reoxygenated Rat Tissues, Charles F. Babbs, Meloney D. Cregor, Stephen F. Badylak Jan 1992

Histochemical Demonstration Of Endothelial Superoxide And Hydrogen Peroxide Generation In Ischemic And Reoxygenated Rat Tissues, Charles F. Babbs, Meloney D. Cregor, Stephen F. Badylak

Weldon School of Biomedical Engineering Faculty Publications

Objective: The aims were to test and evaluate two novel and independent histochemical methods for detecting the initial postischemic burst of superoxide and hydrogen peroxide in buffer perfused rat tissues during reflow after 60 min warm ischemia. Methods: The first is a high manganese/diaminobenzidine technique, in which superoxide oxidises Mn2+ to Mn3+, which in turn oxidizes diaminobenzidine to form amber colored polymers, observable by light microscopy. The second is a high iron/diaminobenzidine technique, in which hydrogen peroxide oxidizes diethylenetriaminepenta-acetate chelated Fe2+ to form intermediate species, which in turn oxidize diaminobenzidine similarly to Mn3+. Various isolated organs of the rat were …

Hierarchical Neural Networks With Forward-Backward Training, S-W. Deng, O. K. Ersoy Jan 1992

Hierarchical Neural Networks With Forward-Backward Training, S-W. Deng, O. K. Ersoy

Department of Electrical and Computer Engineering Technical Reports

A forward-backward training algorithm for parallel, self-organizing hierachical neural networks (PSHNN's) is described. Using linear algebra, it is shown that the forward-backward training of an n-stage PSHNN until convergence is equivalent to the pseudo-inverse solution for a single, total network designed in the leastsquares sense with the total input vector consisting of the actual input vector and its additional nonlinear transformations. These results are also valid when a single long input vector is partitioned into smaller length vectors. A number of advantages achieved are small modules for easy and fast learning, parallel implementation of small modules during testing, faster convergence …


A Generalized Gaussian Image Model For Edge-Preserving Map Estimation, Charles Bouman, Ken Sauer Jan 1992

A Generalized Gaussian Image Model For Edge-Preserving Map Estimation, Charles Bouman, Ken Sauer

Department of Electrical and Computer Engineering Technical Reports

We present a Markov random field model intended to allow realistic edges in maximum a posteriori ( M A P ) image estimates, while providing stable solutions. Similar to the generalized Gaussian distribution used in robust detection and estimation, we proposed the generalized Gaussian Markov random field (GGMRF). This model satisfies several desirable analytical and computational properties for MAP estimation, including continuous dependence of the estimate on the data, invariance of the character of solutions to scaling of data, and a solution which lies at the unique local minimum of the a posteriori log likelihood function. The GGMRF is demonstrated …
