Soliton ratchets in homogeneous nonlinear Klein-Gordon systems
(2006)
We study in detail the ratchetlike dynamics of topological solitons in homogeneous nonlinear Klein-Gordon systems driven by a biharmonic force. By using a collective coordinate approach with two degrees of freedom, namely ...

Vibrational mechanics in higher dimension: Tuning potential landscapes
(American Physical Society, 2021-03)
This work extends the domain of vibrational mechanics to higher dimensions, with fast vibrations applied to different directions. In particular, the presented analysis considers the case of a split biharmonic drive, where ...

Existence of dark solitons in a class of stationary nonlinear Schrödinger equations with periodically modulated nonlinearity and periodic asymptotics
(2011)
In this paper, we give a proof of the existence of stationary dark solitonsolutions or heteroclinic orbits of nonlinear equations of Schrödinger type with periodic inhomogeneous nonlinearity. The result is illustrated with ...

Rate Theory of Acceleration of Defect Annealing Driven by Discrete Breathers
(Springer International Publishing, 2015)
Novel mechanisms of defect annealing in solids are discussed, which are based on the large amplitude anharmonic lattice vibrations, a.k.a. intrinsic localized modes or discrete breathers (DBs). A model for amplification ...

Electrochemical vs antibacterial characterization of ZrCN–Ag coatings
(ScienceDirect, 2015-08-15)
Nowadays, antibacterial properties are becoming a viable feature to be introduced in biomaterials due to the possibility of modifying the materials' surface used in medical devices in a micro/nano metric scale. As a result, ...

Discrete soliton collisions in a waveguide array with saturable nonlinearity
(2006)
We study the symmetric collisions of two mobile breathers/solitons in a model for coupled wave guides with a saturable nonlinearity. The saturability allows the existence of mobile breathers with high power. Three main ...

On the Computation of the Dispersion Diagram of Symmetric One-Dimensionally Periodic Structures
(MDPI, 2018-08)
A critical discussion on the computation of the dispersion diagram of electromagnetic guiding/radiating structures with one-dimensional periodicity using general-purpose electromagnetic simulation software is presented in ...

A 210Pb-based chronological model for recent sediments with random entries of mass and activities: Model development
(Elsevier, 2016)
Unsupported 210Pb (210Pbexc) vs. mass depth profiles do not contain enough information as to extract a unique chronology when both, 210Pbexc fluxes and mass sediment accumulation rates (SAR) independently vary with time. ...

Meteoric 10Be in aerosol filters in the city of Seville
(ScienceDirect, 2019-01)
Cosmogenic radionuclides in the one-million-year half-life range, like 10Be, find application fields in several Sciences. They are powerful tools in Geology and Geochronology, as they are very important tracers on the ...

Enhanced U and Th concentrations in soils from a wet marshland washed by contaminated riverwaters
(Elsevier, 1996)
A study of the presence of U and Th isotopes in soil samples from a saline wet Marshland located close to a phosphoric acid production factory is presented. The samples were collected during low tide in areas washed by ...
