Statistical Power Law due to Reservoir Fluctuations and the Universal Thermostat Independence Principle

Entropy, 2014
Certain fluctuations in particle number, \(n\), at fixed total energy, \(E\), lead exactly to a cut-power law distribution in the one-particle energy, \(\omega\), via the induced fluctuations in the phase-space volume ratio, \(\Omega_n(E-\omega)/\Omega_n(

Circular Polya distributions of order k

International Journal of Mathematics and Mathematical Sciences, 2003
Two circular Polya distributions of order k are derived by means of generalized urn models and by compounding, respectively, the type I and type II circular binomial distributions of order k of Makri and Philippou (1994) with the beta distribution. It is

A beta-Poisson model for infectious disease transmission.

PLoS Computational Biology
Outbreaks of emerging and zoonotic infections represent a substantial threat to human health and well-being. These outbreaks tend to be characterised by highly stochastic transmission dynamics with intense variation in transmission potential between ...

Assessing the adequacy of lymph node yield for different tumor stages of colon cancer by nodal staging scores

BMC Cancer, 2017
Background According to the current official guidelines, at least 12 lymph nodes (LNs) are qualified as an adequate sampling for colon cancer patients. However, patients evaluated with less nodes were still common in the United States, and the prevalence
