New classes of stable exact solutions for a nonlinear rotational DNA model
(Jagellonian University, 2010)
We consider a system of two coupled nonlinear partial differential equations for describing the rotational motions of bases in both polynucleotide chains of the DNA molecule. The model was proposed by L.V. Yakushevich and ...

Impact of the particles impingement on the electronic conductivity of Al doped ZnO films grown by reactive magnetron sputtering
(IOP Science, 2010)
Aluminium doped zinc oxide thin films (4 at.% Al) were deposited by reactive magnetron sputtering technique and characterized by X-ray diffraction (XRD), Rutherford backscattering spectroscopy (RBS), four point probe ...

Las arenas eólicas del Pleistoceno Superior en Gibraltar
(Sociedad Geológica de España, 2010)
During the period represented by the sandy infills of the eastern flank caves and the Catalan Sand formation, it was likely that Gibraltar was part of the mainland, including a broad coastal plain covered with transgressive ...

Symmetries shape the current in ratchets induced by a biharmonic driving force
(2010-03-23)
Equations describing the evolution of particles, solitons, or localized structures, driven by a zero-average, periodic, external force, and invariant under time reversal and a half-period time shift, exhibit a ratchet ...

Nonlinear Schrödinger equation with spatiotemporal perturbations
(2010)
We investigate the dynamics of solitons of the cubic nonlinear Schrödinger equation (NLSE) with the following perturbations: nonparametric spatiotemporal driving of the form f(x,t)=a exp[iK(t)x], damping, and a linear term ...

Generalized traveling-wave method, variational approach, and modified conserved quantities for the perturbed nonlinear Schrödinger equation.
(2010)
The generalized traveling wave method (GTWM) is developed for the nonlinear Schrödinger equation (NLSE) with general perturbations in order to obtain the equations of motion for an arbitrary number of collective coordinates. ...

Solitary waves in a two-dimensional nonlinear Dirac equation: from discrete to continuum
(Institute of Physics (IOP), 2017)
In the present work, we explore a nonlinear Dirac equation motivated as the continuum limit of a binary waveguide array model. We approach the problem both from a near-continuum perspective as well as from a highly discrete ...

New insights on the role of sea ice in intercepting atmospheric pollutants using 129I
(ScienceDirect, 2015-12-15)
Abstract Measurements of 129I carried out on sea ice samples collected in the central Arctic Ocean in 2007 revealed relatively high levels in the range of 100–1400 × 107 at L−1 that are comparable to levels measured in ...
