Superstatistical emission noise
Physica A: Statistical Mechanics and its Applications, 1981 Abstract A model is developed for emission noise in which the mean value itself fluctuates due to modulating processes; the formalism uses compound Poisson statistics. We show that this model is applicable to flicker noise stemming from emission centers, as proposed by Schottky in 1926.

Lagrangian acceleration statistics in turbulent flows
, 2002 We show that the probability densities af accelerations of Lagrangian test particles in turbulent flows as measured by Bodenschatz et al. [Nature 409, 1017 (2001)] are in excellent agreement with the predictions of a stochastic model introduced in [C ...

An Overview of the Pathway Idea and Its Applications in Statistical and Physical Sciences
Axioms, 2015 Pathway idea is a switching mechanism by which one can go from one functional form to another, and to yet another. It is shown that through a parameter α, called the pathway parameter, one can connect generalized type-1 beta family of densities ...

Estimation of Extreme Floods Using a Statistical and Conceptual Model of the Hydrological Response
Water Resources Research, Volume 61, Issue 5, May 2025.Abstract The robust estimation of flood peak discharge values is critical for designing mitigation measures and increasing preparedness to natural hazards. Traditional flood estimation methods are, however, severely limited by data series shorter than the return period of interest, as they only use annual maxima or a few values above a high threshold ...

Weakest-Link Scaling and Extreme Events in Finite-Sized Systems
Entropy, 2015 Weakest-link scaling is used in the reliability analysis of complex systems. It is characterized by the extensivity of the hazard function instead of the entropy.

Complexity, Volume 2025, Issue 1, 2025.Some complex systems (e.g., an ecosystem) in direct contact with an environment can be assigned the temperature of the environment. Other complex systems, such as human beings, can maintain a core temperature of 36.5°C in environments with different temperatures, at least for a short period of time.

Superstatistical fluctuations in time series: Applications to share-price dynamics and turbulence
, 2009 We report a general technique to study a given experimental time series with superstatistics. Crucial for the applicability of the superstatistics concept is the existence of a parameter $\beta$ that fluctuates on a large time scale as compared to the ...

Specific heat and entropy of $N$-body nonextensive systems
, 2010 We have studied finite $N$-body $D$-dimensional nonextensive ideal gases and harmonic oscillators, by using the maximum-entropy methods with the $q$- and normal averages ($q$: the entropic index).

An Overview of Generalized Gamma Mittag–Leffler Model and Its Applications
Axioms, 2015 Recently, probability models with thicker or thinner tails have gained more importance among statisticians and physicists because of their vast applications in random walks, Lévi flights, financial modeling, etc.
