Primordial non-Gaussianity estimator: The inhomogeneous noise effect [PDF]

Physical Review D, 2008
Since the inhomogeneous instrument noise can produce extra non-Gaussianity in the CMB anisotropy, its effect should be carefully subtracted in the primordial non-Gaussianity estimation. We calculate the probability distribution function of the CMB anisotropy for local type of non-Gaussianity, from which the optimal estimator in the general case ...

Non-Gaussian noise induced stochastic resonance in FitzHugh–Nagumo neural system with time delay

AIP Advances, 2020
In this paper, non-Gaussian noise induced stochastic resonance for the FitzHugh–Nagumo neural system with a time delay is investigated. Through the path integral method, the non-Gaussian noise is approximated as a colored noise, and according to the ...

Statistics of voltage fluctuations in resistively shunted Josephson junctions

, 2010
The intrinsic nonlinearity of Josephson junctions converts Gaussian current noise in the input into non-Gaussian voltage noise in the output. For a resistively shunted Josephson junction with white input noise we determine numerically exactly the ...

Effect of time delay on the onset of synchronization of the stochastic Kuramoto model

, 2010
We consider the Kuramoto model of globally coupled phase oscillators with time-delayed interactions, that is subject to the Ornstein-Uhlenbeck (Gaussian) colored or the non-Gaussian colored noise.

Fault-tolerant quantum computation versus Gaussian noise [PDF]

, 2008
We study the robustness of a fault-tolerant quantum computer subject to Gaussian non-Markovian quantum noise, and we show that scalable quantum computation is possible if the noise power spectrum satisfies an appropriate "threshold condition." Our ...

The robust multi‐innovation estimation algorithm for Hammerstein non‐linear systems with non‐Gaussian noise

IET Control Theory & Applications, 2021
The characteristic of the external noise has significant influences on system modelling and identification, and the assumption that the noise follows the Gaussian distribution may be invalid due to realistic reasons.

A random walker on a ratchet potential: Effect of a non Gaussian noise [PDF]

, 2007
We analyze the effect of a colored non Gaussian noise on a model of a random walker moving along a ratchet potential. Such a model was motivated by the transport properties of motor proteins, like kinesin and myosin.

A Novel Approach to 3D-DOA Estimation of Stationary EM Signals Using Convolutional Neural Networks

Sensors, 2020
This paper proposes a novel three-dimensional direction-of-arrival (3D-DOA) estimation method for electromagnetic (EM) signals using convolutional neural networks (CNN) in a Gaussian or non-Gaussian noise environment.
