Radiative Thermal Rectification between SiC and SiO2 [PDF]
, 2015 By means of fluctuationnal electrodynamics, we calculate radiative heat flux between two pla-nar materials respectively made of SiC and SiO2. More specifically, we focus on a first (direct) situation where one of the two materials (for example SiC) is at

The dynamical disconnection of sunspots from their magnetic roots
, 2005 After a dynamically active emergence phase, magnetic flux at the solar surface soon ceases to show strong signs of the subsurface dynamics of its parent magnetic structure. This indicates that some kind of disconnection of the emerged flux from its roots

Post-processing-based Flux-weakening Control of Variable Flux Reluctance Machines
2024 IEEE 21st Biennial Conference on Electromagnetic Field Computation (CEFC)This paper introduces a novel post-processing-based flux-weakening control method for variable flux reluctance machines. The proposed method achieves high-efficiency operation at elevated speeds by determining the optimal values for both ac- and de-field currents together with the commutation angle.

Common and Distinct Drivers of Convective Mass Flux and Walker Circulation Changes
Geophysical Research LettersThe weakening of convective mass flux and the Walker circulation is one of the most robust responses to global warming. However, recent decades have seen the Pacific Walker circulation strengthen despite a weakening convective mass flux. Here, we conduct
