How regular is regular? An analysis of menstrual cycle regularity

Contraception, 2004
We performed a retrospective analysis to ascertain how accurately women who believe that they have regular menstrual cycles estimate the length of their actual cycles. Data were extracted from a chart review of subjects from three different studies of barrier contraceptives.

Regular Nests

2002
A language over a finite alphabet $X$ is regular if it can be accepted by a finite automaton. It is known that the family of all regular languages $L_3$ over $X$ is closed under catenation. This paper is a study of the regular property of the catenation of two languages.

Regular Graphs, Eigenvalues and Regular Factors

Journal of Graph Theory, 2011
AbstractIn this article, we obtain a sufficient condition for the existence of regular factors in a regular graph in terms of its third largest eigenvalue. We also determine all values of k such that every r‐regular graph with the third largest eigenvalue at most has a k‐factor.

Semiregular, weakly regular, and π-regular rings

Journal of Mathematical Sciences, 2002
This is a survey paper related to regular rings and their generalizations. It introduces many rings and modules, such as: semiregular and regular modules, semiregular and regular rings, semiprime and nonsingular rings, weakly \(\pi\)-regular and weakly regular rings, strongly \(\pi\)-regular and \(\pi\)-regular rings, rings of quotients and Pierce ...
