Fully differential cross sections in single ionization of helium by ion impact: Assessing the role of correlated wave functions
(Elsevier Science, 2008-02)
We study the effect of final state dynamic correlation in single ionization of atoms by ion impact analyzing fully differential cross sections (FDCS). We use a distorted wave model where the final state is represented by ...
The parity function in optical waves propagation
(Urban und Fischer Verlag Jena, 2003-12)
We propose a generalization of the concept of parity as a continuous function and show that it is conserved in optical waves free propagation. Some properties are commented and an experimental implementation to optically ...
Nonlinear wave equations related to nonextensive thermostatistics
(Molecular Diversity Preservation International, 2017-02)
We advance two nonlinear wave equations related to the nonextensive thermostatistical formalism based upon the power-law nonadditive Sq entropies. Our present contribution is in line with recent developments, where nonlinear ...
Mathematical Analysis of a Cauchy Problem for the Time-Fractional Diffusion-Wave Equation with α∈ (0 , 2)
(Springer, 2018-04)
This paper deals with a theoretical mathematical analysis of a Cauchy problem for the time-fractional diffusion-wave equation in the upper half-plane, x∈ R, t∈ R+, where the Caputo fractional derivative of order α∈ (0 , ...
Dependence of shear wave seismoelectrics on soil textures: A numerical study in the vadose zone
(Wiley Blackwell Publishing, Inc, 2017-02)
In this work, we study seismoelectric conversions generated in the vadose zone, when this region is traversed by a pure SH wave. We assume that the soil is a 1-D partially saturated lossy porous medium and we use the van ...
Double-bound equivalent of the three-body Coulomb double-continuum wave function
(American Physical Society, 2007-03)
In cross-section calculations of electron or photon double ionization processes of two-electron atoms, it is desirable to have a symmetric description of initial and final states. In this contribution, we search the doubly ...
Continuum theory of gene expression waves during vertebrate segmentation
(IOP Publishing, 2015-09)
The segmentation of the vertebrate body plan during embryonic development is a rhythmic and sequential process governed by genetic oscillations. These genetic oscillations give rise to traveling waves of gene expression ...
Helium atom in a box: Doubly excited levels within the S -wave model
(American Physical Society, 2004-12)
A complete nonperturbative close-coupling solution of the helium atom in a box problem is presented by developing two numerical techniques. The first technique is the direct solution by diagonalization of the Hamiltonian, ...
Rapid estrogen and progesterone signaling to dendritic spine formation via cortactin/wave1-ARP2/3 complex
(Karger, 2019-12-09)
Synaptic plasticity is the neuronal capacity to modify the function and structure of dendritic spines (DS) in response to neuromodulators. Sex steroids, particularly 17β-estradiol (E2) and progesterone (P4), are key ...
Wave turbulence in shallow water models
(American Physical Society, 2014-06)
We study wave turbulence in shallow water flows in numerical simulations using two different approximations: the shallow water model and the Boussinesq model with weak dispersion. The equations for both models were solved ...
