Electrical Sensing of sickled red blood cells subpopulations in microfluidic device

This paper discusses the electrical sensing of red blood cell (RBC) rigidity due to Hemoglobin S (HbS) polymerization in sickle cell disease. For this purpose sickle RBCs subpopulations, differentiated by cell density, were flown through a…

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…
