An Algorithm for Computing Minimum-Length Irreducible Testors

open access: yesIEEE Access, 2020
In pattern recognition, the elimination of unnecessary and/or redundant attributes is known as feature selection. Irreducible testors have been used to perform this task.

Join-irreducible Boolean functions

open access: yes, 2009
This paper is a contribution to the study of a quasi-order on the set $\Omega$ of Boolean functions, the \emph{simple minor} quasi-order. We look at the join-irreducible members of the resulting poset $\tilde{\Omega}$.

SU(N) Irreducible Schwinger Bosons

open access: yes, 2010
We construct SU(N) irreducible Schwinger bosons satisfying certain U(N-1) constraints which implement the symmetries of SU(N) Young tableaues. As a result all SU(N) irreducible representations are simple monomials of $(N-1)$ types of SU(N) irreducible ...

Esophageal hiatal hernia: A report of two cases

open access: yesThe Journal of Association of Chest Physicians
Hiatal hernia (HH) is a condition in which an intraabdominal organ herniates through the esophageal hiatus of the diaphragm. It is rare in the pediatric population due to congenital defects in the diaphragm.

Twisted Quantum Affine Superalgebra $U_q[gl(m|n)^{(2)}]$ and New $U_q[osp(m|n)]$ Invariant R-matrices

open access: yes, 1999
The minimal irreducible representations of $U_q[gl(m|n)]$, i.e. those irreducible representations that are also irreducible under $U_q[osp(m|n)]$ are investigated and shown to be affinizable to give irreducible representations of the twisted quantum ...

STRONGLY IRREDUCIBLE IDEALS [PDF]

open access: yesJournal of the Australian Mathematical Society, 2008
AbstractA proper ideal I of a ring R is said to be strongly irreducible if for each pair of ideals A and B of R, $A\cap B \subseteq I$ implies that either $A \subseteq I$ or $B \subseteq I$. In this paper we study strongly irreducible ideals in different rings.

A Novel Construction of Perfect Strict Avalanche Criterion S-box using Simple Irreducible Polynomials

open access: yesScientific Journal of Informatics, 2020
An irreducible polynomial is one of the main components in building an S-box with an algebraic technique approach. The selection of the precise irreducible polynomial will determine the quality of the S-box produced. One method for determining good S-box

Invariants, Projection Operators and $SU(N)\times SU(N)$ Irreducible Schwinger Bosons

open access: yes, 2011
We exploit SU(N) Schwinger bosons to construct and analyze the coupled irreducible representations of $SU(N) \times SU(N)$ in terms of the invariant group. The corresponding projection operators are constructed in terms of the invariant group generators.

Irreducibility in RNA Structures [PDF]

open access: yesBulletin 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 ...
