Wave turbulence and cortical dynamics

open access: yesFrontiers in Computational Neuroscience
Cortical activity recorded through EEG and MEG reflects complex dynamics that span multiple temporal and spatial scales. Spectral analyses of these signals consistently reveal power-law behavior, a hallmark of turbulent systems.

The effect of strong nonlinearity on wave-induced vertical mixing [PDF]

open access: yesEarth System Dynamics, 2023
A semi-analytical solution to an advection–diffusion equation is coupled with a nonlinear wavemaker model to investigate the effect of strong nonlinearity on wave-induced mixing.

A side-hinged paddle wavemaker

open access: yesArchives of Mechanics, 2023
Theoretical investigations were conducted to study the generation of transient nonlinear water waves by a novel side-hinged paddle wavemaker. A 3D nonlinear solution was derived in a semi-analytical form by applying eigenfunction expansions and FFT.

An analytical model of the evolution of a Stokes wave and its two Benjamin–Feir sidebands on nonuniform unidirectional current [PDF]

open access: yesNonlinear Processes in Geophysics, 2015
An analytical weakly nonlinear model of the Benjamin–Feir instability of a Stokes wave on nonuniform unidirectional current is presented. The model describes evolution of a Stokes wave and its two main sidebands propagating on a slowly varying steady ...

A serpent-type wave energy converter

open access: yesScientific Reports, 2023
The problem of the interaction of waves with a serpent-type wave energy converter was investigated, and a novel 3D analytical solution was derived. The optimal parameters of the energy converter were derived for the first time from wave energy principles.

Ultra-high rate of temperature increment from superparamagnetic nanoparticles for highly efficient hyperthermia

open access: yesScientific Reports, 2021
The magneto-thermal effect, which represents the conversion of magnetostatic energy to heat from magnetic materials, has been spotlighted for potential therapeutic usage in hyperthermia treatments.

DYNAMICS OF TSUNAMI WAVES [PDF]

open access: yes, 2007
The life of a tsunami is usually divided into three phases: the generation (tsunami source), the propagation and the inundation. Each phase is complex and often described separately. A brief description of each phase is given. Model problems are identified. Their formulation is given.

Highly efficient heat-dissipation power driven by ferromagnetic resonance in MFe2O4 (M = Fe, Mn, Ni) ferrite nanoparticles

open access: yesScientific Reports, 2022
We experimentally demonstrated that heat-dissipation power driven by ferromagnetic resonance (FMR) in superparamagnetic nanoparticles of ferrimagnetic MFe2O4 (M = Fe, Mn, Ni) gives rise to highly localized incrementation of targeted temperatures.

Recursive evolution of spin-wave multiplets in magnonic crystals of antidot-lattice fractals

open access: yesScientific Reports, 2021
We explored spin-wave multiplets excited in a different type of magnonic crystal composed of ferromagnetic antidot-lattice fractals, by means of micromagnetic simulations with a periodic boundary condition.
