TLDR
Two versions of a Gaussian signal, corrupted by independent Gaussian noises, are available for estimating the signal-to-noise power ratio and correspondence demonstrates that the sample correlation coefficient can be used to construct an unbiased estimator that is asymptotically efficient.Abstract:

Robust ballistocardiogram acquisition for home monitoring.
TL;DR: A simple, robust method is presented for acquiring high-quality, repeatable BCG signals from a modified, commercially available scale, and the BCG measurement was shown to be repeatable over 50 recordings taken from the same subject over a three week period.

Evoked Brain Potentials and Behavior
TL;DR: In this article, the effects of two kinds of experimental manipulation of semantic meaning were studied in Evoked Potentials (EPs), brain responses recorded from scalp monitors, based on Osgood's rating analyses which described three primary dimensions of connotative meaning: Evaluation, potency, and activity (E, P, and A).

Resolution measures in molecular electron microscopy
TL;DR: This work provides description of standard resolution measures commonly used in electron microscopy and points out that the organizing principle is the relationship between these measures and the spectral signal-to-noise ratio (SSNR) of the computed density map.
Journal ArticleDOI
Three-dimensional spectral signal-to-noise ratio for a class of reconstruction algorithms
TL;DR: A three-dimensional version of the spectral signal-to-noise ratio (SSNR)-based resolution measure is introduced and it is shown that the new measure can be used to evaluate the anisotropy of 3D reconstructions.
Journal ArticleDOI
First pain event related potentials to argon laser stimuli: recording and quantification.
TL;DR: The power of the averaged vertex recorded response was, for the range of intensities considered, the most sensitive parameter to quantify the stimulus and hence the intensity of pain perceived.
