Subharmonic stochastic synchronization and resonance in a neuronal system
(American Physical Society, 2002-10)
We study the response of a model neuron, driven simultaneously by noise and at least two weak periodic signals. We focus on signals with frequencies components kf0,(k+1)f0,…(k+n)f0 with k>1. The neuron’s output is a sequence ...
Resonance switching in a large sonic crystal cavity
(Elsevier, 2017-01)
In this work we present an experimental realization of resonance switching inside a large, relative to the lattice constant, sonic crystal (SC) cavity. The resonances arise from a temporary trapping of the acoustical energy ...
Nuclear structure constrains on resonant energies: a solution of the cosmological Li problem?
(Elsevier Science, 2012-11)
In this work, we study the cosmological 7Li problem from a nuclear structure point of view, by including resonances in the reactions which populate beryllium. The calculation of primordial abundances is performed by solving ...

Proton double irradiation field-cycling nuclear magnetic resonance imaging: Testing new concepts and calibration methods
(Institute of Electrical and Electronics Engineers, 2020-11-11)
Double resonance experiments in field-cycling nuclear magnetic resonance (NMR) are powerful tools for the indirect detection of quadrupolar and electron resonances, dynamic nuclear polarization-induced signal amplification, ...
Resonance capture and dynamics of three-planet systems
(Wiley Blackwell Publishing, Inc, 2018-06)
We present a series of dynamical maps for fictitious three-planet systems in initially circular coplanar orbits. These maps have unveiled a rich resonant structure involving two or three planets, as well as indicating ...

Polariton path to fully resonant dispersive coupling in optomechanical resonators
(American Physical Society, 2014-11)
Resonant photoelastic coupling opens new perspectives for strongly enhanced light-sound interaction in semiconductor optomechanical resonators. One potential problem, however, is the reduction of the cavity Q factor induced ...
Resonant current controller with enhanced transient response for grid-tied inverters
(Institute of Electrical and Electronics Engineers, 2018-04-08)
This paper highlights the limitations of the dynamic response of a grid-tied inverter connected through an inductor $L$ when it is controlled using a proportional+resonant controller. Then, a new resonant current controller ...
