Ballistic charge transport by mobile nonlinear excitations
(Wiley, 2021)
The developments in hyperconductivity, the loss-free transmission of electric charge at room temperature and above, due to the ballistic transport of electric charge in crystals with quasi-layered structure, are reported. ...

Intrinsic localized modes in polymers and hyperconductors
(American Institute of Physics, 2022-12-07)
The history of the experimental study of nonlinear lattice excitations in layered silicate materials, when exposed to swift particles of appreciable momentum is described briefly. For brevity, and because of the difficulty ...

The transport, effective half-lives and age distributions of radioactive releases in the northern Indian Ocean
(Elsevier, 2021)
A Lagrangian model which describes radionuclide transport in the northern Indian Ocean is described. Water circulation is obtained from HYCOM ocean model for year 2017. The model includes advection by currents, turbulent ...

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 Lagrangian Tool for Simulating the Transport of Chemical Pollutants in the Arabian/Persian Gulf
(MDPI, 2021)
A rapid-response Lagrangian model for the use in simulation of the transport of a chemical pollutant in the Arabian/Persian Gulf is described. The model is well suited to the provision of a fast response after an emergency ...

Splitting Methods for Semi-Classical Hamiltonian Dynamics of Charge Transfer in Nonlinear Lattices
(MDPI, 2022-09-22)
We propose two classes of symplecticity-preserving symmetric splitting methods for semi-classical Hamiltonian dynamics of charge transfer by intrinsic localized modes in nonlinear crystal lattice models. We consider, without ...

Tracing the upwelling process in the northern Benguela upwelling system (nBUS) by 129I
(ScienceDirect, 2021-02)
New data on the presence of 129I in seawater in the Southern Hemisphere measured by Accelerator Mass Spectrometry (AMS) is presented. The samples were collected in 2014 along the Namibian coast during a cruise organised ...

Dispersion Analysis of Periodically Loaded Transmission Lines with Twist Symmetry Using the Mode-Matching Technique
(MDPI, 2020)
A mode-matching formulation is presented and used to analyze the dispersion properties of twist-symmetric transmission lines. The structures are coaxial lines periodically loaded with infinitely thin screens, which are ...

Dispersion analysis of periodic structures in anisotropic media: application to liquid crystals
(IEEE Computer Society, 2022)
This paper presents an efficient method to compute the dispersion diagram of periodic and uniform structures with generic anisotropic media. The method takes advantage of the ability of full-wave commercial simulators ...

A comparison of 210Pbxs, 137Cs, and Pu isotopes as proxies of soil redistribution in South Spain under severe erosion conditions
(Springer, 2023-06-01)
Purpose The use of fallout radionuclides as proxies for the study of soil redistribution processes in semiarid environments of Southern Spain has been restricted to 137Cs. The potential and limitations of alternative ...
