Interior proximal bundle algorithm with variable metric for nonsmooth convex symmetric cone programming
(Taylor & Francis, 2016)
This paper is devoted to the study of a bundle proximal-type algorithm for solving the problem of minimizing a nonsmooth closed proper convex function subject to symmetric cone constraints, which include the positive orthant ...
Abelianized obstruction for fixed points of fiber-preserving maps of surface bundles
(Juliusz Schauder Ctr Nonlinear Studies, 2009-06-01)
Let f: M -> M be a fiber-preserving map where S -> M -> B is a bundle and S is a closed surface. We study the abelianized obstruction, which is a cohomology class in dimension 2, to deform f to a fixed point free map by a ...
COINCIDENCE OF MAPS ON TORUS FIBRE BUNDLES OVER THE CIRCLE
(Juliusz Schauder Ctr Nonlinear Studies, 2015-12-01)
The main purpose of this work is to study coincidences of fibre preserving self-maps over the circle S-1 for spaces which are fibre bundles over S' and the fibre is the torus T. We classify all pairs of self-maps over S-1 ...
Coincidence of maps on torus fibre bundles over the circle
(2015-12-01)
The main purpose of this work is to study coincidences of fibre- preserving self-maps over the circle S1 for spaces which are fibre bundles over S1 and the fibre is the torus T. We classify all pairs of self-maps over S1 ...
Abelianized obstruction for fixed points of fiber-preserving maps of surface bundles
(2009-01-01)
Let f:M → M be a fiber-preserving map where S → M → B is a bundle and S is a closed surface. We study the abelianized obstruction, which is a cohomology class in dimension 2, to deform f to a fixed point free map by a ...
A Model for Bundled Conductors considering a Non-Homogeneous Distribution of the Current through Subconductors
(Institute of Electrical and Electronics Engineers (IEEE), 2010-06-01)
This paper describes an alternative procedure to obtain an equivalent conductor from a bundled conductor, taking into account the distribution of the current in subcondutors of the bundle. Firstly, it is introduced a brief ...

Floral vasculature and its variation for carpellary supply in Anthurium (Araceae, Alismatales)
(2017-01-01)
Introduction and Aims. Anthurium is the largest genus of Araceae, with 950 species distributed in the neotropics. Despite the great diversity of the genus, the knowledge of its floral vasculature is based on observations ...
Sustained reduction of healthcare-associated infections after the introduction of a bundle for prevention of ventilator-associated pneumonia in medical-surgical intensive care units
(2020-09-01)
Background: Infection control interventions can be erroneously interpreted if outcomes are assessed in short periods. Also, statistical methods usually applied to compare outcomes before and after interventions are not ...
