Perfect edge domination: hard and solvable cases
(Springer, 2018-05)
Let G be an undirected graph. An edge of Gdominates itself and all edges adjacent to it. A subset E′ of edges of G is an edge dominating set of G, if every edge of the graph is dominated by some edge of E′. We say that E′ ...
Genetic control of fruit-setting percentage of tomatoes tolerant to high temperatures
(2003-12-01)
The aim of present work was to study, through means and variances of generations, the genetic control of fruit-set percentage in tomatoes, in a biparental cross between line Jab-95 (resistant to fruit-set) and 'Caribe' ...

On dominating sets of maximal outerplanar graphs
(Elsevier Science BvAmsterdamHolanda, 2013)
Is the Brazil Current eddy-dominated to the north of 20 degrees S?
(AMER GEOPHYSICAL UNION, 2011)
The Brazil Current (BC) originates with the arrival and bifurcation of the southernmost branch of the South Equatorial Current (sSEC) between 10-20 degrees S. Previous climatological studies showed a stratified sSEC ...
Grass dominance drives rhizospheric bacterial communities in a desertic shrub and grassy steppe highland
(Elsevier Gmbh, 2017-05)
The rhizosphere is a dynamic root-soil interface characterized by interactions between soil microorganisms and roots. These interactions can be potential drivers of the structure of the plant and bacterial communities in ...
On the complexity of the minimum domination problem restricted by forbidden induced subgraphs of small size
(Elsevier Science, 2015-12)
We study the computational complexity of the minimum dominating set problem on graphs restricted by forbidden induced subgraphs. We give some dichotomies results for the problem on graphs defined by any combination of ...
Sign conditions for the existence of at least one positive solution of a sparse polynomial system
(Academic Press Inc Elsevier Science, 2020-12)
We give sign conditions on the support and coefficients of a sparse system of d generalized polynomials in d variables that guarantee the existence of at least one positive real root, based on degree theory and Gale duality. ...
Economic viability and selection of irrigation systems using simulation and stochastic dominanceViabilidade econômica e seleção de sistemas de irrigação utilizando simulação e dominância estocástica
(2009-01-01)
In humid areas, irrigation systems are used to increase the crop yield. The selection of irrigation system to be used is a decision made under uncertainty. This paper shows a procedure that is an association between Monte ...
