Traitement du signal et de l'image

Investigation of analog signal distortion introduced by a fiber phase sensitive amplifier

We numerically simulate the distortion of an analog signal carried in a microwave photonics link containing a phase sensitive amplifier (PSA), focusing mainly on amplitude modulation format. The numerical model is validated by comparison with…

Optimization of laser dynamics for active stabilization of DF-VECSELs dedicated to cesium CPT clocks

We report the implementation and performance of a double servo-loop for intensity and phase-difference active stabilization of a dual-frequency vertical external-cavity surface-emitting laser (DF-VECSEL) for coherent pop- ulation trapping (CPT) of…

Oxidative stress activates red cell adhesion to laminin in sickle cell disease

Vaso-occlusive crises are the hallmark of sickle cell disease (SCD). They are believed to occur in two steps, starting with adhesion of deformable low-dense red blood cells (RBCs), or other blood cells such as neutrophils, to the wall of post…

Dynamics of mode-locked nanolasers based on Hermite-Gaussian modes

The different dynamical behaviors of the Hermite-Gaussian (HG) modes of mode-locked nanolasers based on a harmonic photonic cavity are investigated in detail using a model based on a modified Gross-Pitaevskii Equation. Such nanolasers are shown to…

Delivery of siRNA to Ewing Sarcoma Tumor Xenografted on Mice, Using Hydrogenated Detonation Nanodiamonds: Treatment Efficacy and Tissue Distribution

Nanodiamonds of detonation origin are promising delivery agents of anti-cancer therapeutic compounds in a whole organism like mouse, owing to their versatile surface chemistry and ultra-small 5 nm average primary size compatible with natural…

Supraconductivité

Study of the Superconducting to Normal Transition

A model, based on classical mechanics and thermodynamics and valid for all superconductors, is devised to investigate the properties of the current-driven, superconducting to normal transition. This process is shown to be reversible. An original…
