Balancedness of some subclasses of circular-arc graphs
(Elsevier Science, 2010-08)
A graph is balanced if its clique-vertex incidence matrix is balanced, i.e., it does not contain a square submatrix of odd order with exactly two ones per row and per column. Interval graphs, obtained as intersection graphs ...
Dynamic homology and circularity in cladistic analysis
(Springer, 2020-02)
In this article, I examine the issue of the alleged circularity in the determination of homologies within cladistic analysis. More specifically, I focus on the claims made by the proponents of the dynamic homology approach, ...

β-sheet to α-helix conversion and thermal stability of β-Galactosidase encapsulated in a nanoporous silica gel
(Academic Press Inc Elsevier Science, 2019-01-01)
The effect on protein conformation and thermal stability was studied for β-Galactosidase (β-Gal) encapsulated in the nanopores of a silicate matrix (Eβ-Gal). Circular dichroism spectra showed that, compared with the enzyme ...
Circuits and Circulant Minors
(Elsevier, 2019)
Circulant contraction minors play a key role for characterizing ideal circular matrices in terms of minimally non ideal structures. In this article we prove necessary and sufficient conditions for a circular matrix A to ...

Two-dimensional solution and analysis of a cylindrical matrix device with a circular release area
(TAYLOR & FRANCIS INC, 2013-01-01)
A cylindrical device was analyzed using a Laplace transform-based method. The two-dimensional model represented a pharmaceutical agent uniformly distributed in a polymeric matrix surrounded by an impermeable layer. Molecules ...
Análise de antenas de microfita com patches circulares sobre substratos anisotrópicos usando o método dos potenciais de Hertz
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia ElétricaAutomação e Sistemas; Engenharia de Computação; Telecomunicações, 2005-03-31)
This work consists on the theoretical and numerical analysis of some properties of circular microstrip patch antennas on isotropic and uniaxial anisotropic substrates. For this purpose, a full wave analysis is performed, ...
Iniciativas relacionadas con economía circular para el aprovechamiento de residuos de un solo uso (poliestireno expandido EPS)
This work is a documentary review oriented to the analysis, description and selection of efficient alternatives for the use and return to the production chain of expanded polystyrene or EPS that applies the variables of ...
