Electrofocusing in natural pH gradients formed by buffers: Gradient modification

Analytical Biochemistry, 1977
Abstract Natural pH gradients formed in buffers (1) can be shifted in slope or in parallel along the pH scale by addition or substitution of buffers to obtain, for each particular fractionation problem, a gradient in which the species of interest occupies the center position.

Gradient direction dependencies in natural images

Spatial Vision, 2007
We have used information-theoretic measures to compute the amount of dependency which exists between two and three gradient directions at separate locations in an ensemble of natural images. Control experiments were performed on other image classes: phase randomized natural images, whitened natural images and Gaussian noise images.

Natural Gradient for Minor Component Extraction

2005 IEEE International Symposium on Circuits and Systems, 2005
The paper proposes constrained optimization criteria for extracting in parallel multiple minor components using a weighted inverse Rayleigh quotient (WIRQ). This WIRQ is formulated into many constrained optimization problems which results in deriving many variations of MCA flows using the natural gradient concept.
