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 Rings are Very Regular

Canadian Mathematical Bulletin, 1982
The following problem arose in a conversation with Abraham Zaks: “Suppose R is an associative ring with identity such that every finitely generated left ideal is generated by idempotents. Is R von-Neumann regular?” In the literature the “s” in “idempotents” is missing, and is replaced by “an idempotent”. The answer is, “Yes!”

Regular Categories and Regular Functors

Canadian Journal of Mathematics, 1974
Let be a category with nice factorization-properties. If a functor G: —> which has a left-adjoint behaves nice with respect to factorizations then it can be shown quite easily that G behaves well in many other respects, especially that it lifts nice properties from into .

Balanced-by-Construction Regular and ω-Regular Languages

International Journal of Foundations of Computer Science, 2021
Parenn is the typical generalization of the Dyck language to multiple types of parentheses. We generalize its notion of balancedness to allow parentheses of different types to freely commute. We show that balanced regular and [Formula: see text]-regular languages can be characterized by syntactic constraints on regular and [Formula: see text]-regular ...

Spectral regularization and minEnt regularization

IEEE International Conference on Acoustics Speech and Signal Processing, 2002
In this paper, we propose the spectral regularization based on the conventional (spatial) regularization and the Fourier analysis. The entropy regularization is further developed and its connection to MinEnt principle is investigated. The underlying geometrical, physical and biological interpretation of spectral and entropic regularization are ...

On regular and regularised varieties

Algebra Universalis, 1986
Let V be an irregular variety defined by a set of regular identities and an identity of the form \(t(x,y)=t(x,z)\). (Any irregular variety can be defined in such a way.) A variety \(\bar V\) containing the regularization of V is introduced and studied. It has the following properties. \(\bar V\) is finitely based if V is.
