Hadamard Conjugation for the Kimura 3ST Model: Combinatorial Proof Using Path Sets
Under a stochastic model of molecular sequence evolution the probability of each possible pattern of characters is well defined. The Kimura's three-substitution-types (K3ST) m...

Discrete conservation of nonnegativity for elliptic problems solved by the hp-FEM
Most results related to discrete nonnegativity conservation principles (DNCP) for elliptic problems are limited to finite differences (FDM) and lowest-order finite element meth...

An approach to membrane computing under inexactitude
In this paper we introduce a fuzzy version of symport/antiport membrane systems. Our fuzzy membrane systems handle possibly inexact copies of reactives and their rules are endowed...

Icosahedra Constructed from Congruent Triangles
It is possible to construct a figure in 3 dimensions which is combinatorially equivalent to a regular icosahedron, and whose faces are all congruent but not equilateral. Such icos...

A Theory of Hierarchical Consequence and Conditionals
We introduce A-ranked preferential structures and combine them with an accessibility relation. A-ranked preferential structures are intermediate between simple preferential struct...
