Collapse and diffusion in harmonic activation and transport

open access: yesForum of Mathematics, Sigma, 2023
For an n-element subset U of $\mathbb {Z}^2$ , select x from U according to harmonic measure from infinity, remove x from U and start a random walk from x. If the walk leaves from y when it first enters the rest of U, add y to it.

New error bounds for linear complementarity problems of weakly chained diagonally dominant B-matrices

open access: yesOpen Mathematics, 2017
Some new error bounds for the linear complementarity problems are obtained when the involved matrices are weakly chained diagonally dominant B-matrices. Numerical examples are given to show the effectiveness of the proposed bounds.

Multiscale Estimation of Cell Kinetics

open access: yesComputational and Mathematical Methods in Medicine, Volume 11, Issue 3, Page 239-254, 2010., 2010
We introduce a methodology based on the Luria–Delbrück fluctuation model for estimating the cell kinetics of clonally expanding populations. In particular, this approach allows estimation of the net cell proliferation rate, the extinction coefficient and the initial (viable) population size.

A strong law of large numbers for independent compactly uniformly integrable random sets [PDF]

open access: yesArab Journal of Mathematical Sciences
PurposeThe aim of this work is to prove a strong law of large numbers for a sequence of independent compactly uniformly integrable random sets with values in the family of convex closed subsets of a separable Banach space E, again without requiring any ...

A discrete and finite approach to past physical reality

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 19, Page 1003-1023, 2004., 2004
This paper is a synthesis of previously published material on the topic. We show that an adequate mathematical model for the physical (i.e., perceptible and therefore past) reality must be finite. A finite approach to past proper time is given. Proper time turns out to be proportional to the sum of the return probabilities of a Bernoulli random walk.

The distribution of quadratic residues and non-residues in the Goldwasser–Micali type of cryptosystem. II

open access: yesJournal of Mathematical Cryptology, 2015
We provide three statistical laws concerning the limit distribution of quadratic residues and quadratic non-residues in ℤ/Nℤ${\mathbb {Z}/N\mathbb {Z}}$, where N=pq${{N= pq}}$ is an RSA modulus used in the Goldwasser–Micali cryptosystem.

On the order of growth of convergent series of independent random variables

open access: yesInternational Journal of Stochastic Analysis, Volume 2004, Issue 2, Page 159-168, 2004., 2004
For independent random variables, the order of growth of the convergent series Sn is studied in this paper. More specifically, if the series Sn converges almost surely to a random variable, the tail series is a well‐defined sequence of random variables and converges to 0 almost surely.

First hitting times of simple random walks on graphs with congestion points

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 30, Page 1911-1922, 2003., 2003
We derive the explicit formulas of the probability generating functions of the first hitting times of simple random walks on graphs with congestion points using group representations.

Cauchy approximation for sums of independent random variables

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 17, Page 1055-1066, 2003., 2003
We use Stein′s method to find a bound for Cauchy approximation. The random variables which are considered need to be independent.
