Journal ArticleDOI
Seeing through the photoreceptor mosaic
TL;DR: The cone array in the peripheral retina, unlike the fovea, is sparse and irregular, and it feeds an even sparser ganglion cell array, which provides a new challenge to establish the link between the organization of the retina and the psychophysical limits of visual resolution.

Analysis of multicomponent AM-FM signals using FB-DESA method
Ram Bilas Pachori,Pradip Sircar +1 more
TL;DR: The proposed Fourier-Bessel expansion-based discrete energy separation algorithm (FB-DESA) method does not introduce any amplitude or phase modulation in the separated monocomponent signal leading to accurate estimations of the AE and IF functions.

Efficient Spectral Simulations in NMR of Rotating Solids. The γ-COMPUTE Algorithm
TL;DR: In this article, the authors explore the time-translational relation between one of the powder angles (gamma) and the sample rotation angle (omegart) in NMR spectroscopy of rotating solids.
Journal ArticleDOI
In) Sensitivity to spatial distortion in natural scenes
TL;DR: The results suggest that the detection of distortion involves decisions made in the late stages of image perception and is based on an expectation of the typical structure of natural scenes.

Efficient representation of the North Atlantic hydrographic and chemical distributions
Ichiro Fukumori,Carl Wunsch +1 more
TL;DR: In this article, a form of empirical onthogonal function (principal component analysis) based upon the singular value decomposition is used to identify the minimum data set necessary to describe the general circulation and identify the dominant physical characteristics of the North Atlantic Ocean.
