Homogenization of the Navier-Stokes equations by means of the Multi-scale Virtual Power Principle
(Elsevier Science Sa, 2017-03)
This work addresses the multi-scale modeling of fluid flow in highly complex media based on the concept of Representative Volume Element (RVE). The Method of Multi-scale Virtual Power developed by the authors is employed ...
Scaling coexistence and assemblage patterns of desert small mammals
Scaling biodiversity patterns has been recognized lately as a very important issue in the search of global processes; however coexistence and assemblage patterns are typically approached at a single spatial scale. Here, ...
The Brazilian version of the Neuropsychiatric Inventory-Clinician rating scale (NPI-C): Reliability and validity in dementia
ABSTRACT Background: Patients with dementia may be unable to describe their symptoms, and caregivers frequently suffer emotional burden that can interfere with judgment of the patient's behavior. The Neuropsychiatric ...
Emergence of allometric scaling in genealogical trees

Finite size scaling in the local abundances of geographic populations
We analyzed the statistical distribution of intra-specifi c local abundances for a set North American breeding bird species. We constructed frequency plots for every species and found that they showed long-tail power-law ...
Filippov's selection theorem and the existence of solutions for optimal control problems in time scales
We obtain an extension of Filippov's Lemma to control systems in time scales, where the multifunction associated with the dynamics is delta measurable on time and Lipschitz on the state variable. Using a modified version ...
Scaling of the 1-halo terms with bias
In the Halo Model, galaxies are hosted by dark matter haloes, while the haloes themselves are biased tracers of the underlying matter distribution. Measurements of galaxy correlation functions include contributions both ...
Scaling functions evaluation for estimation of landscape metrics at higher resolutions
(Elsevier Science, 2014-07)
Understanding the relationship between landscape pattern and environmental processes requires quantification of landscape pattern at multiple scales. This will make it possible to relate broad-scale patterns to fine-scale ...
Lagrangian scheme to model subgrid-scale mixing and spreading in heterogeneous porous media
(American Geophysical Union, 2017)
Small-scale heterogeneity of permeability controls spreading, dilution, and mixing of solute plumes at large scale. However, conventional numerical simulations of solute transport are unable to resolve scales of heterogeneity ...
Scale morphology of Prochilodus lineatus with emphasis on the scale epithelium
