Measurement Invariance, Entropy, and Probability

open access: yesEntropy, 2010
We show that the natural scaling of measurement for a particular problem defines the most likely probability distribution of observations taken from that measurement scale.

Superstatistical analysis of sea-level fluctuations [PDF]

open access: yesPhysica A: Statistical Mechanics and its Applications, 2015
We perform a statistical analysis of measured time series of sea levels at various coastal locations in the UK, measured at time differences of 15 minutes over the past 20 years. When the astronomical tide and other deterministic components are subtracted, a stochastic signal remains which is well-described by a superstatistical model.

Sensitivity of Regulated Streamflow Regimes to Interannual Climate Variability

open access: yesEarth's Future, Volume 7, Issue 11, Page 1206-1219, November 2019., 2019
The simultaneous growth in climate‐driven alterations of the hydrologic cycle and global freshwater demand threatens the security of anthropogenic and ecologic uses of streamflows. However, the impact of damming on the response of river regimes to long‐term climate variability has not been fully disclosed yet.

First-passage time: a conception leading to superstatistics

open access: yesCondensed Matter Physics, 2006
To describe the nonequilibrium states of a system we introduce a new thermodynamic parameter -- the lifetime (the first passage time) of a system. The statistical distributions that can be obtained out of the mesoscopic description characterizing the ...

A Generalization of the Havrda‐Charvat and Tsallis Entropy and Its Axiomatic Characterization

open access: yesAbstract and Applied Analysis, Volume 2014, Issue 1, 2014., 2014
In this communication, we characterize a measure of information of types α, β, and γ by taking certain axioms parallel to those considered earlier by Havrda and Charvat along with the recursive relation Hn(p1, …, pn; α, β, γ) ‐ Hn−1(p1 + p2, p3, …, pn; α, β, γ) = (A(α,γ)/(A(α,γ) − A(β,γ)))p1+p2α/γH2(p1/(p1+p2), p2/(p1 + p2); α,γ) + (A(β,γ)/(A(β,γ) − A ...

Conditional maximum entropy and superstatistics [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2020
Abstract Superstatistics describes nonequilibrium steady states as superpositions of canonical ensembles with a probability distribution of temperatures. Rather than assume a certain distribution of temperature, recently [2020 J. Phys. A: Math. Theor. 53 045004] we have discussed general conditions under which a system

On superstatistics and black hole quasinormal modes

open access: yesPhysics Letters B, 2022
It is known that using Boltzmann-Gibbs statistics, Bekenstein-Hawking entropy SHB, and the quasinormal modes of black holes, one finds that the lowest value of spin is jmin=1.

Random diffusivity from stochastic equations: comparison of two models for Brownian yet non-Gaussian diffusion

open access: yesNew Journal of Physics, 2018
A considerable number of systems have recently been reported in which Brownian yet non-Gaussian dynamics was observed. These are processes characterised by a linear growth in time of the mean squared displacement, yet the probability density function of ...

Stochastic interpolation of sparsely sampled time series by a superstatistical random process and its synthesis in Fourier and wavelet space

open access: yesJournal of Physics: Complexity, 2023
We present a novel method for stochastic interpolation of sparsely sampled time signals based on a superstatistical random process generated from a multivariate Gaussian scale mixture.

Functional identities in superstatistics [PDF]

open access: yesAIP Conference Proceedings, 2016
Superstatistics is a relatively new proposal to explain the success of non-Boltzmann-Gibbs probability distributions in out-of-equilibrium systems and non-extensive systems. It amounts to a marginalization of the inverse temperature parameter β = 1/kBT over the joint distribution P(x, β|S).
