Resistive drift instabilities for thermal and non-thermal electron distributions in electron-ion plasma

Heliyon, 2018
Local dispersion relations for resistive drift mode in a nonuniform magnetize plasma are derived for thermal and non-thermal distribution of electrons.

Time-fractional effect on dust-acoustic double-layer waves in four-component dusty plasma

Results in Physics, 2019
The Gardener equation (GE) is resulting by using reductive perturbation technique (RPT) for a system of dusty plasma of opposite polarity and kappa-distributed electrons and ion.

Kappa-deformed random-matrix theory based on Kaniadakis statistics

, 2012
We present a possible extension of the random-matrix theory, which is widely used to describe spectral fluctuations of chaotic systems. By considering the Kaniadakis non-Gaussian statistics, characterized by the index {\kappa} (Boltzmann-Gibbs entropy is

Empirical Emission Functions for LPM Suppression of Photon Emission from Quark-Gluon Plasma

, 2002
The LPM suppression of photon emission rates from the quark gluon plasma have been studied at different physical conditions of the plasma given by temperature and chemical potentials.The integral equation for the transverse vector function (f(p_t ...

Magnetic Spectra Comparison for Kappa-distributed Whistler Electron Fluctuations

The Astrophysical Journal
In the inner heliosphere, space measurements have revealed that plasma is well described by the kappa distributions, which are characterized by the value of the κ parameter.

A nonextensive entropy approach to solar wind intermittency

, 2004
The probability distributions (PDFs) of the differences of any physical variable in the intermittent, turbulent interplanetary medium are scale dependent.

Kappa-tail Technique: Modeling and Application to Solar Energetic Particles Observed by Parker Solar Probe

The Astrophysical Journal
We develop the kappa-tail fitting technique, which analyzes observations of power-law tails of distributions and energy flux spectra, and connects them to theoretical modeling of kappa distributions, to determine the thermodynamics of the examined space ...

Distribution of shifted discrete random walk generated by distinct random variables and applications in ruin theory

Modern Stochastics: Theory and Applications
In this paper, the distribution function \[ \varphi (u)=\mathbb{P}\Bigg(\underset{n\geqslant 1}{\sup }{\sum \limits_{i=1}^{n}}({X_{i}}-\kappa )\lt u\Bigg),\] and the generating function of $\varphi (u+1)$ are set up.

Using multi-parameters distributions to assess the probability of occurrence of extreme rainfall data

Revista Brasileira de Engenharia Agrícola e Ambiental, 2014
Soil erosion, soil saturation and floods are frequently associated with extreme rainfall events. Thus, the scientific literature agrees on the need to carry out studies that improve the assessment of the probability of occurrence of extreme rainfall ...
