Equational definability of (complementary) central elements
(World Scientific, 2016-05)
For a variety with weak existentially definable factor congruences, we characterize whenthe properties "e is a central element" and "e and f are complementary central elements"are definable by (∀ V p = q)-formulas and by ...

Mechanics of the maxillary central incisor. Influence of the periodontal ligament represented by beam elements
(Taylor & Francis Ltd, 2010-01-01)
This study aimed to evaluate the influence of loading on a maxillary central incisor with the periodontal ligament (PDL) represented by 2D elastic beam elements using a 2D finite element analysis. Two models (M) were built ...

Ancestral polymorphism and recent invasion of transposable elements in Drosophila species
(Biomed Central Ltd., 2012-07-23)
Background: During the evolution of transposable elements, some processes, such as ancestral polymorphisms and horizontal transfer of sequences between species, can produce incongruences in phylogenies. We investigated the ...
