we present a detailed study of the spinel CdEr2Se4 and show it to be a new instance of spin ice, the first one in an erbium material and the first one in a spinel. Definitive experimental evidence comes from the temperature dependence of the magnetic entro ...
Two ITER IF dual channel Cable-in-Conduit Conductors (CICCs) have been tested in the SULTAN test facility. The samples were heated either by foil heaters mounted on the outside of the conductor jacket or by induced AC losses. The steady-state temperature r ...
In this work we introduce the use of the per-band link control method in cascades of distributed fiber Raman amplifiers (DFRAs) for compensating power transients of WDM channels. By using two compensation channels, each one controlled by a proportional-int ...
The coupling current loss in rectangular superconducting cables is strictly dependent on their aspect ratio, which has an impact on the area linked by the field variation and consequently on the currents induced between strands. The relation between the ac ...
We investigate the propagation of temperature perturbations in an array of coupled nonlinear oscillators at finite temperature. We evaluate the response function at equilibrium and show how the memory effects affect the diffusion properties. A comparison w ...
In this work, by using a comprehensive numerical model which rigorously describes the interaction between stimulated Raman scattering (SRS) and four-wave mixing (FWM), we verify that FWM processes, including depletion and parametric gain, generate a redist ...
The aim of this paper is to present an experimental validation of a frequency- domain approach to the solution of the lightning electromagnetic field-to- buried cable coupling equations. The coupling to the inner conductor is evaluated using the concept of ...
Increased miniaturization of surgical instruments is essential to successfully perform surgical procedures in restricted areas as in many applications of minimally-invasive surgery. Miniaturization permits increase in dexterity and decrease in access incis ...
In this work, by means of numerical simulations, we verify that four‐wave mixing (FWM) processes, including depletion and parametric gain, generate a redistribution of pump power in distributed fiber Raman amplifiers (DFRAs). As a consequence of pump‐pump ...
The degradation of the performance of distributed fiber Raman amplifiers (DFRAs) is shown to be dependent on the interaction between pump-pump four-wave mixing (FWM) and stimulated Raman scattering (SRS), by means of numerical simulations. We verify that F ...
