7 J an 1 99 9 Connection between Dispersive Transport and Statistics of Extreme Events

چکیده
A length dependence of the effective mobility in the form of a power law, B ∼ L 1− 1 α is observed in dispersive transport in amorphous substances, with 0 < α < 1. We deduce this behavior as a simple consequence of the statistical theory of extreme events. We derive various quantities related to the largest value in samples of n trials, for the exponential and power-law probability densities of the individual events.

Recent experimental tests of the symmetrization postulate of quantum mechanics are discussed. It is shown that in a strict sense these experiments cannot test the validity of the symmetrization postulate, but in most cases do test the spin-statistics connection. An experiment is proposed that would allow to search for possible violations of the symmetrization postulate. Typeset using REVTEX 1
متن کاملStochastic and Dependence Comparisons Between Extreme Order Statistics in the Case of Proportional Reversed Hazard Model
Independent random variables $Y_{1},ldots ,Y_{n}$ belongs to the proportional reversed hazard rate (PRHR) model with proportionality parameters $lambda_1,...,lambda_n$, if $Y_{k}sim G^{lambda _{k}}(x)$, for $k=1,...,n$, where $G$ is an absolutely continuous distribution function. In this paper we compare the smallest order statistics, the sample ranges and th...
متن کاملExtreme-value statistics from Lagrangian convex hull analysis for homogeneous turbulent Boussinesq convection and MHD convection
We investigate the utility of the convex hull ofmany Lagrangian tracers to analyze transport properties of turbulent flowswith different anisotropy. In direct numerical simulations of statistically homogeneous and stationaryNavier–Stokes turbulence, neutral fluid Boussinesq convection, and MHDBoussinesq convection a comparisonwith Lagrangian pair dispersion shows that convex hull statistics cap...
متن کاملSpatial analysis of climate change in Iran
Introduction Climate change is the greatest price society is paying for decades of environmental neglect. The impact of global warming is most visible in the rising threat of climate-related natural disasters. Globally, meteorological disasters more than doubled, from an average of forty-five events a year to almost 120 events a year (Vinod, 2017). Climate change refers to changes in the distr...

Recent numerical results for a model describing dispersive transport in rice piles are explained by mapping the model to the depinning transition of an interface that is dragged at one end through a random medium. The average velocity of transport vanishes with system size L as < v >∼ L2−D ∼ L−0.23, and the avalanche size distribution exponent τ = 2 − 1/D ≃ 1.55, where D ≃ 2.23 from interface d...
