Higher-order spin noise statistics

New Journal of Physics, 2013
The optical spin noise spectroscopy (SNS) is a minimally invasive route toward obtaining dynamical information about electrons and atomic gases by measuring mesoscopic time-dependent spin fluctuations. Recent improvements of the sensitivity of SNS should

Technical Report: Compressive Temporal Higher Order Cyclostationary Statistics [PDF]

IEEE Transactions on Signal Processing, 2014
The application of nonlinear transformations to a cyclostationary signal for the purpose of revealing hidden periodicities has proven to be useful for applications requiring signal selectivity and noise tolerance.

Motion estimation using higher order statistics [PDF]

IEEE Transactions on Image Processing, 1996
The objective of this paper is to introduce a fourth-order cost function of the displaced frame difference (DFD) capable of estimating motion even for small regions or blocks. Using higher than second-order statistics is appropriate in case the image sequence is severely corrupted by additive Gaussian noise.

Detection of multiplicative noise in stationary random processes using second- and higher order statistics [PDF]

, 2000
This paper addresses the problem of detecting the presence of colored multiplicative noise, when the information process can be modeled as a parametric ARMA process.

Higher-order Statistics of Weak Lensing Shear and Flexion [PDF]

, 2010
Owing to their more extensive sky coverage and tighter control on systematic errors, future deep weak lensing surveys should provide a better statistical picture of the dark matter clustering beyond the level of the power spectrum.

Adaptation to changes in higher-order stimulus statistics in the salamander retina.

PLoS ONE, 2014
Adaptation in the retina is thought to optimize the encoding of natural light signals into sequences of spikes sent to the brain. While adaptive changes in retinal processing to the variations of the mean luminance level and second-order stimulus ...

Recurrence relations for higher moments of order statistics from doubly truncated Burr distribution

Statistica, 2014
In this paper, we have obtained recurrence relations for higher moments of order statistics from doubly truncated Burr distribution, which enable one to obtain all the single, double (product) and higher moments of any order of all order statistics for ...
