Collapse models with non-white noises II: particle-density coupled noises

, 2008
We continue the analysis of models of spontaneous wave function collapse with stochastic dynamics driven by non-white Gaussian noise. We specialize to a model in which a classical "noise" field, with specified autocorrelator, is coupled to a local ...

Constellation Optimization in the Presence of Strong Phase Noise

, 2013
In this paper, we address the problem of optimizing signal constellations for strong phase noise. The problem is investigated by considering three optimization formulations, which provide an analytical framework for constellation design.

Paley–Wiener Theorem for White Noise Analysis

Journal of Functional Analysis, 2000
The author generalizes the Paley-Wiener theorem (known from the distributional Fourier transform theory) to an infinite-dimensional white noise space \(({\mathcal E}',\mu)\), where \({\mathcal E}'\) is the dual of nuclear space \({\mathcal E}\) and \(\mu\) is the Gaussian measure on \({\mathcal E}'\).

Effects of white noise on preterm infants in the neonatal intensive care unit: A meta‐analysis of randomised controlled trials

Nursing Open
Aim To critically assess the effects of white noise on the pain level, weight gain and vital signs (heart rate, respiratory rate and oxygen saturation) of preterm infants in neonatal intensive care units (NICUs).

Effect of realistic and filtered stellar photometric noise on the detection of moons using photometric transit timing

EPJ Web of Conferences, 2011
The photometric transit timing technique was proposed by Szabó et al. (2006) as a method for discovering moons of transiting extrasolar planets. In the preliminary analysis of this technique, it was assumed that the noise in the transit lightcurve was ...

Kolmogorov analysis of pulsar TOA

Astronomy & Astrophysics
The Kolmogorov stochasticity parameter (KSP) as a sensitive descriptor of the degree of randomness of signals was used to analyze the properties of the NANOGrav pulsar timing data associated with a stochastic gravitational wave background.
