On structural completeness versus almost structural completeness problem: A discriminator varieties case study
(Oxford University Press, 2014-12)
We study the following problem: determine which almost structurally complete quasivarieties are structurally complete. We propose a general solution to this problem and then a solution in the semisimple case. As a consequence, ...
On structural completeness versus almost structural completeness problem : a discriminator varieties case study
(2015)
We study the following problem: determine which almost structurally complete quasivarieties are structurally complete. We propose a general solution to this problem and then a solution in the semisimple case. As a consequence, ...
Isometries of almost-Riemannian structures on Lie groups
(2018)
A simple Almost-Riemannian Structure on a Lie group G is defined by a linear vector field (that is an infinitesimal automorphism) and dim(G) - 1 left-invariant ones. It is first proven that two different ARSs are isometric ...
Soliton Almost Kähler Structures on 6-Dimensional Nilmanifolds for the Symplectic Curvature Flow
(Springer, 2015-10)
The aim of this paper is to study self-similar solutions to the symplectic curvature flow on 6-dimensional nilmanifolds. For this purpose, we focus our attention on the family of symplectic two- and three-step nilpotent ...
Early bilateral and massive compromise of the frontal lobes.
The frontal lobes are one of the most complex brain structures involved in both domain-general and specific functions. The goal of this work was to assess the anatomical and cognitive affectations from a unique case with ...
Structural Model for the Spider Silk Protein Spidroin-1
(Amer Chemical Soc, 2015-09-01)
Most reports about the 3-D structure of spidroin-1 have been proposed for the protein in solid state or for individual domains of these proteins. A gel-based mass spectrometry strategy using collision-induced dissociation ...
SITUACIÓN ACTUAL, USO Y EXPECTATIVAS DE LA INFRAESTRUCTURA FERROVIARIA EN LA CIUDAD DE MÉXICO Y SU ZONA METROPOLITANA
(2012-11-26)
Over many years, decades and even could talk about almost a full century, the use of Railway Infrastructure in Mexico City, and the rest of the country, was something almost necessarily mandatory, not only for transporting ...
A comparison between internal protein nanoenvironments of α-helices and β-sheets
(2020-12-01)
Secondary structure elements are generally found in almost all protein structures revealed so far. In general, there are more β-sheets than α helices found inside the protein structures. For example, considering the PDB, ...
Pleistocene extinction and geographic singularity explain differences in global felid ensemble structure
(Springer, 2021-04)
Extant felids are hyper-carnivorous predators that originated in Asia c. 11 Mya and diversified in 8 distinct lineages, with 41 species surviving to the Recent. These species occupy almost every terrestrial habitat available ...
