A geometric mass-preserving redistancing scheme for the level set function
(John Wiley & Sons Ltd, 2011-02-09)
In this paper we describe and evaluate a geometric mass-preserving redistancing procedure for the level set function on general structured grids. The proposed algorithm is adapted from a recent finite element-based method ...
Measuring complexity in three-trophic level systems
(ELSEVIER SCIENCE BV, 2009)
This essay is a trial on measuring complexity in a three-trophic level system by using a convex function of the informational entropy. The complexity measure defined here is compatible with the fact that real complexity ...
Differences in the levels of adaptation, social support and family functionality according to the sex, age and school grade of children and adolescents affected by winter in Sucre, Colombia
(Academia Nacional de Medicina venezolana., 2022)
Linking biological soil crust attributes to the multifunctionality of vegetated patches and interspaces in a semiarid shrubland
Understanding the importance of biotic community structure on ecosystem functioning,
and whether communities inhabiting different microhabitats in highly heterogeneous
areas provide different ecological functions is a ...
Level-continuity of functions and applications

On eigenvalue accumulation for non-self-adjoint magnetic operators
(ELSEVIER SCIENCE BV, 2017)
In this work, we use regularized determinants to study the discrete spectrum generated by relatively compact non-self-adjoint perturbations of the magnetic Schrodinger operator (-i del - A)(2) -b in R-3, with constant ...
A perda de grupos funcionais em comunidades virtuais: efeito das interações entre espécies e grupos funcionais
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em EcologiaBioecologia Aquática, 2012-08-27)
High levels of local, regional, and global extinctions has progressively simplified communities in terms of both species and ecosystem functioning. Theoretical models demonstrated that the degree of functional redundancy ...
Associations between socioeconomic status, aging and functionality among older women
(Elsevier, 2017)
To assess if there is an association between socioeconomic status and quality of life, functional status and markers of aging, we studied 86 women aged 73 7 years, who answered the WHO Qol Bref quality of life survey. Mini ...
Hybrid Treatments Based on Determinant Seniority Numbers and Spatial Excitation Levels in the Configuration Interaction Framework
(Elsevier Academic Press Inc, 2018-01)
In this work we project the Hamiltonian of an N-electron system onto a set of N-electron determinants cataloged by their seniority numbers and their excitation levels with respect to a reference determinant. We show that, ...
