Neighborhood Approximations for Non-Linear Voter Models

open access: yesEntropy, 2015
Non-linear voter models assume that the opinion of an agent depends on the opinions of its neighbors in a non-linear manner. This allows for voting rules different from majority voting. While the linear voter model is known to reach consensus, non-linear

Flexible distribution functions, higher-order preferences and optimal portfolio allocation [PDF]

open access: yes, 2019
In this paper we show that flexible probability distribution functions, in addition to been able to capture stylized facts of financial returns, can be used to identify pure higher-order effects of investors' optimizing behavior.

Thermodynamic phase transition of Euler-Heisenberg-AdS black hole on free energy landscape

open access: yesNuclear Physics B, 2023
We study the first order phase transition of Euler-Heisenberg-AdS black hole based on free energy landscape. By solving the Fokker-Planck equation, we research the probability distribution of the system states.

Gamma-shadowed two-ray with diffuse power composite fading model

open access: yesAlexandria Engineering Journal, 2023
In this paper, a novel gamma-shadowed two-ray with diffuse power (GS-TWDP) composite fading model is proposed by assuming that the shadowing-caused mean power variations of the received signal, affected by TWDP multipath fading, are gamma distributed ...

Non-poissonian Distribution of Point Mutations in DNA

open access: yesFrontiers in Chemistry, 2020
In general, for chemical reactions occurring in systems, where fluctuations are not negligibly small, it is necessary to introduce a master equation for distribution of probability of fluctuations. It has been established that the monomolecular reactions

Lesser Sunda Islands Earthquake Inter-occurrence Times Distribution Modeling

open access: yesInternational Journal of Technology, 2014
This paper is aimed towards analyzing and modeling earthquake interoccurence times in the Lesser Sunda Islands region using Weibull distribution. The data were classified into three categories, based on their magnitude; i.e.

Excitation and breakup of [pi]+[pi]--atoms at high energies [PDF]

open access: yes, 2003
The DIRAC collaboration at CERN currently aims at measuring the lifetime of pionium (π + π − -atoms) with an accuracy of 10%. This is a crucial test of Chiral Perturbation Theory which predicts the lifetime to be (2.9 ± 0.1) fs.
