Nodal solutions of an NLS equation concentrating on lower dimensional spheres
(2015-12-26)
In this work we deal with the following nonlinear Schrödinger equation: {−<sup>ϵ2</sup>Δu+V(x)u=f(u)in <sup>RN</sup>u∈<sup>H1</sup>(<sup>RN</sup>),(Formula presented.) where N≥3, f is a subcritical power-type nonlinearity ...
Phenotypic variation of south-western Atlantic clam Mactra isabelleana (Bivalvia: Mactridae)
(Cambridge University Press, 2012)
The phenotypic shell shape variation of Mactra isabelleana was tested using the geometric morphometric method. Four localities were sampled along the Río de la Plata estuary and the coast of Buenos Aires province. Principal ...
Geographical and intrapopulation variation in the diet of a threatened marine predator, Pontoporia blainvillei (Cetacea)
(Wiley-Blackwell, 2018-01-01)
Understanding diet variation is a major concern when developing conservation guidelines for threatened species, especially for marine predators whose prey availability can be reduced by commercial fisheries. Diet can vary ...
Secular variation of births, weight and length at birth: local perspective
(2015)
Objective: To analyse the outcomes of births and anthropometric measurements at birth of children born between 1974 and 2011 at Limache Hospital (Valparaiso, Chile). Patients and method: Times series were constructed of ...
Some remarks on the interpretation of the local atomic reactivity indices within the Klopman Peradejordi Gomez (KPG) method. I. Theoretical analysis
(RJPBCS Research Journal Pharmaceutical, 2018)
The Klopman-Peradejordi-Gomez method relates the variation of a biological activity, measured in vivo or in vitro, with the variation of the numerical values of a set of local atomic reactivity indices (LARIs). The ...
Geometric Integrators for Higher-Order Variational Systems and Their Application to Optimal Control
(Springer, 2016-12-01)
Numerical methods that preserve geometric invariants of the system, such as energy, momentum or the symplectic form, are called geometric integrators. In this paper we present a method to construct symplectic-momentum ...
Local Linearization-Runge-Kutta methods: a class of A-stable explicit integrators for dynamical systems
(Pergamon-Elsevier Science Ltd, 2013-02)
A new approach for the construction of high order A-stable explicit integrators for ordinary differential equations (ODEs) is theoretically studied. Basically, the integrators are obtained by splitting, at each time step, ...
Soliton solutions for quasilinear Schrödinger equations: the critical exponential case
(Nonlinear Analysis: Theory, Methods & Applications, 2018)
Spatially-antisymmetric localization of matter wave in a bichromatic optical lattice
(Iop Publishing Ltd, 2010-11-01)
By direct numerical simulation of the time-dependent Gross-Pitaevskii equation using the split-step Fourier spectral method we study the double-humped localization of a cigar-shaped Bose-Einstein condensate (BEC) in a ...
