Analysis of the stability and dispersion for a Riemannian acoustic wave equation
(ELSEVIER SCIENCE INC, 2019-01-15)
The construction of images of the Earth's interior using methods as reverse time migration (RTM) or full wave inversion (FWI) strongly depends on the numerical solution of the wave equation. A mathematical expression of ...
The evolution of dispersal traits based on diaspore features in South American populations of Senecio madagascariensis (Asteraceae)
(Csiro Publishing, 2019-08)
Plant invasion success is influenced by several driving factors such as the dispersal, environmental conditions and the species characteristics. In wind dispersed plants, the dispersal traits and the altitude are key for ...
Cooper pair dispersion relation for weak to strong coupling
(American Physical Soc, 2000-10-01)
Cooper pairing in two dimensions is analyzed with a set of renormalized equations to determine its binding energy for any fermion number density and all coupling assuming a,generic pairwise residual interfermion interaction. ...
Decomposing recruitment limitation for an avian-dispersed rain forest tree in an anciently fragmented landscape
(British Ecological Society, 2013)
1. Forest fragmentation may intensify recruitment limitation through impacts on seed production,
dissemination and seedling establishment processes. In an ancient mosaic of fog-dependent rain forest
patches on coastal ...
Early genetic consequences of defaunation in a large-seeded vertebrate-dispersed palm (Syagrus romanzoffiana)
(Nature Publishing Group, 2017-01)
Plant populations are seriously threatened by anthropogenic habitat disturbance. In particular, defaunation may disrupt plant-disperser mutualisms, thus reducing levels of seed-mediated gene flow and genetic variation in ...
Behavior of the PMD coefficient of optical links under influence of mechanical and thermal effects
(2004-12-01)
This papers presents results on the variation of the PMD coefficient of optical links under influence of mechanical tests, such as tensile strength, bending and compression, and also during the application of a thermal ...
Selection of surfactant compounds to enhance the dispersion of Beauveria bassiana
(Taylor & Francis Ltd, 2014)
Diversification of the widespread neotropical frog Physalaemus cuvieri in response to Neogene-Quaternary geological events and climate dynamics
(Elsevier B.V., 2019-03-01)
Here we reconstructed the demographical history and the dispersal dynamics of Physalemus cuvieri through the Neogene-Quaternary periods by coupling DNA regions with different mutation rates, ecological niche modelling, ...
Nonlinear effects generation in suspended core chalcogenide fibre
(2011-06-15)
In this work we report our achievements in the elaboration and optical characterizations of low-losses suspended core optical fibers elaborated from As2S3 glass. For preforms elaboration, alternatively to other processes ...
