The paper studies (non-Gaussian) diffusions classified as either ``hypo-diffusion'' or ``hyper-diffusion'', where the \(\beta\) order moments are of the type \(t^{\beta/\alpha}\), with \(\beta\) and \(\alpha\) belonging to \(\mathbb{R}^*_+\). The authors introduce signed measures corresponding to non-Gaussian diffusions on \(\mathbb{R}\), inspired by ...

Detection of non-Gaussian signals in non-Gaussian noise using the bispectrum
IEEE Transactions on Acoustics, Speech, and Signal Processing, 1990The problem of detecting a non-Gaussian time series in the presence of additive Gaussian or non-Gaussian noise is cast into a classical hypothesis testing framework, using the sample bispectrum as the test statistic. The power of the test is demonstrated as a function of signal-to-noise ratio, the degree of skewness of the signal, and processing ...

LENGTH OF INFLATION AND NON-GAUSSIANITY
International Journal of Modern Physics D, 2011Certain inflation models are shown to have large non-Gaussianity in special cases. Namely, slow-roll inflation models with an effective higher derivative interaction, in which the length of inflation is finite and a scalar-matter-dominated period or power inflation is adopted as pre-inflation, are considered.

The non-Gaussian dynamics of glycerol
Journal of Physics: Condensed Matter, 2011We have combined incoherent quasielastic neutron scattering experiments and atomistic molecular simulations to investigate the microscopic dynamics of glycerol moving away from the hydrodynamic limit. We relate changes in the momentum transfer (Q) dependence of the relaxation time to distinct changes of the single-particle dynamics. Going from small to

Complex information in single-channel synthetic aperture radar (SAR) imagery is seldom used. This is a common practice based on the conventional resolution theory.

Weak non-Gaussian approximation
Physical Review E, 1995A superposition of Gaussian functionals is considered as a trial functional for the Bogoliubov inequality. The direct optimization of the Bogoliubov inequality generates a non-Gaussian approximation. This function may be strongly non-Gaussian but the kernel is the same as the usual one, up to a multiplicative constant.

DETECTION OF NON-GAUSSIAN PROCESSES IN NON GAUSSIAN NOISE
1963Abstract : The detection of stochastic processes in noise is considered, under the assumption that neither the signal nor the noise need be Gaussian. The detector structure is found in terms of the semiinvariants of the signal and noise processes. The general detector structure is extremely complicated, but a threshold form may be obtained.

Coloring Non-Gaussian Sequences
IEEE Transactions on Signal Processing, 2008We propose a novel method for generating random sequences matching both a target non-Gaussian distribution and a target autocorrelation. In the proposed scheme, samples matching the target distribution are drawn independently and then suitably rearranged to match the target autocorrelation.

Non-Gaussian fluctuations in opsins
2013 22nd International Conference on Noise and Fluctuations (ICNF), 2013We investigate conductance fluctuations of two transmembrane proteins, bacteriorhodopsin and proteorhodopsin, belonging to the family of opsins. These proteins are sensitive to visible light and are promising biomaterials for the realization of novel photodevices.
