Blind Separation of Cyclostationary Sources Using Joint Block Approximate Diagonalization
This paper introduces an extension of an earlier method of the author for separating stationary sources, based on the joint approximated diagonalization of interspectral matrices, ...

Finding Patterns in Given Intervals
In this paper, we study the pattern matching problem in given intervals. Depending on whether the intervals are given a priori for pre-processing, or during the query along with th...

A Weakly 2-Random Set That Is Not Generalized Low
A guiding question in the study of weak 2-randomness is whether weak 2-randomness is closer to 1-randomness, or closer to 2randomness. Recent research indicates that the first alte...

Finite-sample performance guarantees for one-dimensional stochastic root finding
We study the one-dimensional root finding problem for increasing convex functions. We give gradient-free algorithms for both exact and inexact (stochastic) function evaluations. ...

A periodic boundary value problem with vanishing Green's function
In this work, the authors consider the boundary value problem y + a(t)y = g(t) f (y), 0 t 2, y(0) = y(2), y (0) = y (2), and establish the existence of nonnegative solutions in ...
