Irreducibility in RNA Structures [PDF]
Bulletin of Mathematical Biology, 2009 In this paper we study irreducibility in RNA structures. By RNA structure we mean RNA secondary as well as RNA pseudoknot structures. In our analysis we shall contrast random and minimum free energy (mfe) configurations. We compute various distributions: of the numbers of irreducible substructures, their locations and sizes, parameterized in terms of ...

Quasifields with irreducible nuclei
International Journal of Mathematics and Mathematical Sciences, 1984 This article considers finite quasifields having a subgroup N of either the right or middle nucleus of Q which acts irreducibly as a group of linear transformations on Q as a vector space over its kernel. It is shown that Q is a generalized André system,

Combined matrix of diagonally equipotent matrices
Special Matrices, 2023 Let C(A)=A∘A−T{\mathcal{C}}\left(A)=A\circ {A}^{-T} be the combined matrix of an invertible matrix AA, where ∘\circ means the Hadamard product of matrices.

Irreducible modules with highest weight vectors over modular Witt and special Lie superalgebras
Open Mathematics, 2019 Let 𝔽 be an arbitrary field of characteristic p > 2. In this paper we study irreducible modules with highest weight vectors over Witt and special Lie superalgebras of 𝔽.

Irreducible triangulations are small [PDF]
Journal of Combinatorial Theory, Series B, 2010 A triangulation of a surface is \emph{irreducible} if there is no edge whose contraction produces another triangulation of the surface. We prove that every irreducible triangulation of a surface with Euler genus $g\geq1$ has at most $13g-4$ vertices. The best previous bound was $171g-72$.

Otherness: The Prevalence of the Real
Rivista di Estetica, 2014 The paper considers three uses of the real in literature that bear witness to what I would call “prevalence” of the real as the ultimate otherness. The first concerns the way in which the real bursts into fiction; the latter does indeed draw from the ...

An irreducibility criterion for polynomials in several variables [PDF]
, 2000 We prove that if K is a finite extension of Q, P is the set of prime numbers in Z that remain prime in the ring R of integers of K, f, g∈K[X] with degg>degf and f, g are relatively prime, then f+pg is reducible in K[X] for at most a finite number of ...

Irreducibility and efficiency of ESIP to sample marker genotypes in large pedigrees with loops
Genetics Selection Evolution, 2002 Markov chain Monte Carlo (MCMC) methods have been proposed to overcome computational problems in linkage and segregation analyses. This approach involves sampling genotypes at the marker and trait loci.

Irreducibility of configurations
Ars Mathematica Contemporanea, 2015 In a paper from 1886, Martinetti enumerated small $v_3$-configurations. One of his tools was a construction that permits to produce a $(v+1)_3$-configuration from a $v_3$-configuration. He called configurations that were not constructible in this way irreducible configurations.
