Exponentially Fitted Two-Derivative Runge-Kutta Methods for Simulation of Oscillatory Genetic Regulatory Systems. [PDF]
Oscillation is one of the most important phenomena in the chemical reaction systems in living cells. The general purpose simulation algorithms fail to take into account this special character and produce unsatisfying results. In order to enhance the accuracy of the integrator, the secondāorder derivative is incorporated in the scheme.

Idempotent-separating extensions of regular semigroups
For a regular biordered set E, the notion of E-diagram and the associated regular semigroup was introduced in our previous paper (1995). Given a regular biordered set E, an E-diagram in a category C is a collection of objects, indexed by the elements of ...

\textit{K. S. S. Nambooripad} [Mem. Am. Math. Soc. 224 (1979; Zbl 0457.20051)] introduced the concept of a (regular) biordered set to abstractly characterize the set of idempotents of a regular semigroup. He also described the biordered sets associated with bands.

Biordered sets come from semigroups
The biordered set of a semigroup is the set of idempotents of the semigroup together with the partial operation obtained by restriction of the multiplication to those pairs of idempotents whose product is equal to one of them (i.e. one is a one-sided zero of the other).

Biordered sets and complemented modular lattices
In this paper we give a structure theorem for the biordered set of a strongly regular Baer semigroup. As a result we shall be able to construct the biordered set of the multiplicative semigroup of a regular ring in terms of the complemented modular lattice which is coordinatized by this regular ring.

Reconstructing some idempotent-generated semigroups from their biordered sets
The authors investigate how many informations on a semigroup \(S\) are given by the partial algebra \(E(S)\) of the idempotents of \(S\) where a product of \((e,f)\) is defined iff, under the multiplication of \(S\), \(ef\) or \(fe\) is equal to one of its factors. \(E(S)\) is the biordered set of \(S\).

A concept of variety for regular biordered sets
A regular biordered set \((E,\cdot,\omega^ l, \omega^ r)\) is a set \(E\) together with two quasiorders \(\omega^ l\) and \(\omega^ r\) and a partial binary operation \(\cdot\), satisfying a finite (but somehow complicated) system of axioms. Regular biordered sets were introduced by \textit{K. S. S. Nambooripad} [Mem. Am. Math. Soc. 224 (1979; Zbl 0457.

In [4] K.S.S. Nambooripad introduced biordered sets as a partial algebra $\left(E, \omega^r, \omega^l\right)$ where $\omega^r$ and $\omega^l$ are two quasiorders on the set $E$ satisfying biorder axioms; to study the structure of a regular semigroup.

Biordered sets are biordered subsets of idempotents of semigroups [PDF]
AbstractA new arrow notation is used to describe biordered sets. Biordered sets are characterized as biordered subsets of the partial algebras formed by the idempotents of semigroups. Thus it can be shown that in the free semigroup on a biordered set factored out by the equations of the biordered set there is no collapse of idempotents and no new ...
