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 second‐order derivative is incorporated in the scheme.

Beyond Regular Semigroups [PDF]
The topic of this thesis is the class of weakly U-abundant semigroups. This class is very wide, containing inverse, orthodox, regular, ample, adequate, quasi-adequate, concordant, abundant, restriction, Ehresmann and weakly abundant semigroups.

Maximal subgroups of free idempotent-generated semigroups over the full transformation monoid [PDF]
Let Tn be the full transformation semigroup of all mappings from the set {1, . . . , n} to itself under composition. Let E = E(Tn) denote the set of idempotents of Tn and let e ∈ E be an arbitrary idempotent satisfying |im (e)| = r ≤ n − 2. We prove that

Every group is a maximal subgroup of the free idempotent generated semigroup over a band [PDF]
Given an arbitrary group G we construct a semigroup of idempotents (band) BG with the property that the free idempotent generated semigroup over BG has a maximal subgroup isomorphic to G. If G is finitely presented then BG is finite. This answers several

On maximal subgroups of free idempotent generated semigroups [PDF]
We prove the following results: (1) Every group is a maximal subgroup of some free idempotent generated semigroup. (2) Every finitely presented group is a maximal subgroup of some free idempotent generated semigroup arising from a finite semigroup.

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.

Efficacy of Non-Linear Approach in the Study of Ozone Layer Depletion [PDF]
The stratosphere is one of the constituents of thermal structure of the atmosphere. The maximum concentration of ozone is found at the stratospheric region where it is interacted by many species including chemical and physical processes.

Free idempotent generated semigroups over bands and biordered sets with trivial products [PDF]
For any biordered set of idempotents [Formula: see text] there is an initial object [Formula: see text], the free idempotent generated semigroup over[Formula: see text], in the category of semigroups generated by a set of idempotents biorder-isomorphic to [Formula: see text].

Biordered Sets of Regular Rings
The set of idempotents of a regular semigroup is given an abstract characterization as a regular biordered set in [2], and in [4] it is shown how a biordered set can be associated with a complemented modular lattice. Von Neumann has shown earlier that any complemented modular lattice of order greater than 3 can be realized as the lattice of principal ...
