Dynamical Universal Behavior in Quantum Chaotic Systems

open access: yes, 2010
We discover numerically that a moving wave packet in a quantum chaotic billiard will always evolve into a quantum state, whose density probability distribution is exponential.

Efficiency of polymerase chain reaction processes: A stochastic model [PDF]

open access: yes, 2006
A stochastic model for the efficiency of polymerase chain reaction (PCR) processes is presented. The model is based on the assumption that the i’th nucleotide incorporation on the DNA template takes τi seconds, where τi has an exponential distribution ...

Generalized Exponentiated Moment Exponential Distribution [PDF]

open access: yes, 2014
Moment distributions have a vital role in mathematics and statistics, in particular in probability theory, in the perspective research related to ecology, reliability, biomedical field, econometrics, survey sampling and in life-testing.

Distribution of volumes and coordination number in jammed matter: mesoscopic ensemble

open access: yes, 2010
We investigate the distribution of the volume and coordination number associated to each particle in a jammed packing of monodisperse hard sphere using the mesoscopic ensemble developed in Nature 453, 606 (2008).

Distributional properties of exponential functionals of Levy processes [PDF]

open access: yes, 2012
We study the distribution of the exponential functional $I(\xi,\eta)=\int_0^{\infty} \exp(\xi_{t-}) \d \eta_t$, where $\xi$ and $\eta$ are independent L\'evy processes.

Possible canonical distributions for finite systems with nonadditive energy

open access: yes, 2008
It is shown that a small system in thermodynamic equilibrium with a finite thermostat can have a q-exponential probability distribution which closely depends on the energy nonextensivity and the particle number of the thermostat.

Exponential Distribution of Locomotion Activity in Cell Cultures [PDF]

open access: yes, 1998
In vitro velocities of several cell types have been measured using computer controlled video microscopy, which allowed to record the cells' trajectories over several days.

Simple and accurate modelling of the gravitational potential produced by thick and thin exponential discs [PDF]

open access: yes, 2015
We present accurate models of the gravitational potential produced by a radially exponential disc mass distribution. The models are produced by combining three separate Miyamoto–Nagai discs.

Phase Transitions in Edge-Weighted Exponential Random Graphs: Near-Degeneracy and Universality

open access: yes, 2018
Conventionally used exponential random graphs cannot directly model weighted networks as the underlying probability space consists of simple graphs only. Since many substantively important networks are weighted, this limitation is especially problematic.

Multivariate Matrix-Exponential Distributions [PDF]

open access: yesStochastic Models, 2010
We review what is currently known about one-dimensional distributions on the non-negative reals with rational Laplace transform, also known as matrix-exponential distributions. In particular we discuss a flow interpreation which enables one to mimic certain probabilisticly inspired arguments which are known from the theory of phase-type ...
