Geometric proprieties of invariant connections on View the MathML source
(2003)
This article describes some geometric aspects of a class of affine connections in homogeneous spaces, that emerged in an earlier paper by the authors, related to the geometry of statistical models. We describe the geodesics ...
Geometric proprieties of invariant connections on SL(n, R)/SO(n)
(Elsevier Science BvAmsterdamHolanda, 2003)
Lorentz Connections and Gravitation
(American Institute of Physics (AIP), 2012-01-01)
The different roles played by Lorentz connections in general relativity and in teleparallel gravity are reviewed. Some of the consequences of this difference are discussed.
Effect of pre and postnatal retinal deprivation on the striate-peristriate cortical connections in the rat
(1994)
The tangential distribution of the striate-peristriate cortical connections in normal, postnatally eye enucleated and congenitally anophthalmic rats, was studied after a single injection of wheat germ agglutinin conjugated ...
A Finite Element Stress Analysis of a Concical Triangular Connection in Implants: A New Proposal
(MDPI, 2022)
Conical implant–abutment connections are popular for their stability; however, in other conditions, such as excessive force, implants and abutments can absorb all the stress. Some connections with three points of support ...
A big-world network in ASD: Dynamical connectivity analysis reflects a deficit in long-range connections and an excess of short-range connections
(Pergamon-Elsevier Science Ltd, 2011-11)
Over the last years, increasing evidence has fuelled the hypothesis that Autism Spectrum Disorder (ASD) is a condition of altered brain functional connectivity. The great majority of these empirical studies relies on ...
Comparison of external and internal implant-abutment connections for implant supported prostheses. A systematic review and meta-analysis
(2018-03-01)
Objective: The systematic review and meta-analysis aimed to answer the PICO question: “Do patients that received external connection implants show similar marginal bone loss, implant survival and complication rates as ...
Approximation algorithms for connected graph factors of minimum weight
(Springer, 2018)
Finding low-cost spanning subgraphs with given degree and connectivity requirements is a fundamental problem in the area of network design. We consider the problem of finding d-regular spanning subgraphs (or d-factors) of ...
A Berger-type theorem for metric connections with skew-symmetric torsion
(Elsevier Science, 2012-12)
We prove a Berger-type theorem which asserts that if the orthogonal subgroup generated by the torsion tensor (pulled back to a point by parallel transport) of a metric connection with skew-symmetric torsion is not transitive ...
