On recurrence relations for radial wave functions for the N-th dimensional oscillators and hydrogenlike atoms: analytical and numerical study
(2006)
Using a general procedure for finding recurrence relations for hypergeometric functions and polynomials introduced by Cardoso et al. [J. Phys. A 36 (2003), 2055-2068] we obtain some new recurrence relations for the ...

Compositional depth profiling analysis of thin and ultrathin multilayer coatings by radio-frequency glow discharge optical emission spectroscopy
(ScienceDirect, 2006-06-20)
In most of the industrial applications of multilayer coatings, a detailed knowledge of the interlayer structure and the interfaces is needed. In comparison with standard surface analysis techniques (SIMS, XPS, AES, etc.), ...

Modelling surface radioactive spill dispersion in the Alboran Sea
(Elsevier, 2006)
The Strait of Gibraltar and the Albora´n Sea are the only connection between the Atlantic Ocean and the Mediterranean Sea. Intense shipping activities occur in the area, including transport of waste radionuclides and ...

Radiationless traveling waves in saturable nonlinear Schrödinger lattices
(2006)
The long-standing problem of moving discrete solitary waves in nonlinear Schrödinger lattices is revisited. The context is photorefractive crystal lattices with saturable nonlinearity whose grand-canonical energy barrier ...

Assessment of state-of-the-art models for predicting the remobilisation of radionuclides following the flooding of heavily contaminated areas: the case of Pripyat River floodplain
(Elsevier, 2006)
The performances of models are assessed to predict the wash-off of radionuclides from contaminated flooded areas. This process should be accounted for in the proper management of the aftermath of a nuclear accident. The ...

Pattern imaging of primary and secondary electrohydrodynamic instabilities
(Cambridge University Press, 2006-02-08)
A little known electrohydrodynamic instability, which we call a rose window, is observed in air/liquid interfaces in electric fields with unipolar space charge distributions. Depending on the liquid properties, the rose ...

Existence of bound states of a polaron with a breather in soft potentials
(2006)
We consider polarons in models of coupled electronic and vibrational degrees of freedom, in the presence of a soft nonlinear substrate potential (Morse potential). In particular, we focus on a bound state of a polaron with ...

Growth of CrNx films by DC reactive magnetron sputtering at constant N2/Ar gas flow
(ScienceDirect, 2006-05-22)
Chromium nitride coatings have been deposited on silicon by magnetron sputtering in an Ar + N2 atmosphere at different bias substrate voltages. The poisoning effect has been studied monitoring the discharge voltage and ...

Domain wall dynamics in expanding spaces
(2006)
We study the effects on the dynamics of kinks due to expansions and contractions of the space. We show that the propagation velocity of the kink can be adiabatically tuned through slow expansions and/or contractions, while ...

Nanometric resolution in glow discharge optical emission spectroscopy and Rutherford backscattering spectrometry depth profiling of metal (Cr, Al) nitride multilayers
(ScienceDirect, 2006-05)
In this work, we address the capability of glow discharge optical emission spectroscopy (GDOES) for fast and accurate depth profiling of multilayer nitride coatings down to the nanometer range. This is shown by resolving ...
