Coupled cell networks: Boolean perspective
Biomath, 2017 During the 1980s and early 1990s, Martin Golubitsky and Ian Stewart formulated and developed a theory of "coupled cell networks" (CCNs). Their research was primarily focused onquadrupeds' gaits and they applied the framework of differential equations ...

Semilattices of finitely generated ideals of exchange rings with finite stable rank
, 2004 We find a distributive (v, 0, 1)-semilattice S of size $ aleph\_1$ that is not isomorphic to the maximal semilattice quotient of any Riesz monoid endowed with an order-unit of finite stable rank.

The relations among invariants of points on the projective line [PDF]
, 2009 We consider the ring of invariants of n points on the projective line. The space (P^1)^n // PGL_2 is perhaps the first nontrivial example of a Geometry Invariant Theory quotient. The construction depends on the weighting of the n points. Kempe discovered

Research, 2022 The manipulation on turn-on fluorescence in solid state materials attracts increasing interests owing to their widespread applications. Herein we report how the nonradiative pathways of tetraphenylpyrazine (TPP) units in metal−organic frameworks (MOFs ...

Product structure of heat phase space and branching Brownian motion
, 2003 A generical formalism for the discussion of Brownian processes with non-constant particle number is developed, based on the observation that the phase space of heat possesses a product structure that can be encoded in a commutative unit ring.

Quadratic form theory over preordered von Neumann-regular rings [PDF]
, 2008 To each pair, 〈R,T〉, consisting of a unitary commutative von Neumann-regular ring, R, where 2 is a unit and T is a preorder on R, we associate a reduced special group, GT(R), which faithfully reflects quadratic form theory, modulo T, over free R-modules ...

Heliyon, 2023 This work uses ab-initio CBS-QB3 and density functional theory (B3LYP) to analyze the structure, stability, and aromaticity of all isosteric nitrogen-boron pyrroles.

On feedback invariants for linear dynamical systems [PDF]
, 2001 The goal of this paper is to prove that, if R is a commutative ring containing a (non-zero) finitely generated maximal ideal M containing its annihilator, such that every unit of R/M lifts to a unit of R, then the category of reachable systems over R is “

Beilstein Journal of Organic Chemistry, 2013 The ring opening of the Dewar form of 1,2-dihydro-1,2-azaborine, 2-aza-3-borabicyclo[2.2.0]hex-5-ene (3) is investigated by theoretical methods by using multiconfiguration SCF (CASSCF) and coupled cluster theory [CCSD(T)] with basis sets up to polarised ...

Acta Crystallographica Section E: Crystallographic Communications, 2019 The title compound, C20H16Cl2N2O3S, is built up from a dihydrobenzothiazine moiety linked by –CH– and –C2H4– units to 2,4-dichlorophenyl and 2-oxo-1,3-oxazolidine substituents, where the oxazole ring and the heterocyclic portion of the ...
