Josephson tunnelling of dark solitons in a double-well potential
(2011)
We study the dynamics of matter waves in an effectively one-dimensional Bose-Einstein condensate in a double-well potential. We consider in particular the case when one of the double wells confines excited states. Similar ...

Multibreather and vortex breather stability in Klein–Gordon lattices: equivalence between two different approaches
(2011)
In this work, we revisit the question of stability of multibreather configurations, i.e. discrete breathers with multiple excited sites at the anti-continuum limit of uncoupled oscillators. We present two methods that yield ...

Surface characterization of Ti-Si-C-ON coatings for orthopedic devices: XPS and Raman spectroscopy
(ScienceDirect, 2011-01)
Ti–Si–C–ON films were deposited by DC reactive magnetron sputtering and their chemical properties, biofilm formation and toxicity were characterized. Based on the films composition three different growth regimes were ...

Ag–Ti(C, N)-based coatings for biomedical applications: influence of silver content on the structural properties
(IOP Science, 2011-08-26)
Ag–TiCN coatings were deposited by dc reactive magnetron sputtering and their structural and morphological properties were evaluated. Compositional analysis showed the existence of Ag–TiCN coatings with different Ag/Ti ...

Current reversals in a rocking ratchet: the frequency domain
(American Physical Society, 2011)
Motivated by recent work [D. Cubero et al., Phys. Rev. E 82, 041116 (2010)], we examine the mechanisms which determine current reversals in rocking ratchets as observed when varying the frequency of the drive. We found ...

Drain flow and related salt losses as affected by phosphogypsum amendment in reclaimed marsh soils from SW Spain
(Elsevier, 2011)
Phosphogypsum (PG), a by-product of the P industries, has been widely applied as an amendment to reduce Na saturation in soils. However, some concern arises due to its content of some metals and radionuclides. Thus, it ...
