Open AccessThe quantum-optics Hamiltonian in the Multipolar gauge
This article deals with the fundamental problem of light-matter interaction in the quantum theory. Although it is described through the vector potential in quantum electrodynamics, it is believed by some that ...

Open AccessQuantum metamaterials in the microwave and optical ranges
Quantum metamaterials generalize the concept of metamaterials (artificial optical media) to the case when their optical properties are determined by the interplay of quantum effects in the constituent ‘artific...

Heat transfer between a hot AFM tip and a cold sample: impact of the air pressure
We observe the heat flux exchanged by the hot tip of a scanning thermal microscope, which is an instrument based on the atomic force microscope. We first vary the pressure in order to analyze the impact on the...

Radiative heat transfer at the nanoscale
Heat can be exchanged between two surfaces through emission and absorption of thermal radiation. It has been predicted theoretically that for distances smaller than the peak wavelength of the blackbody spectru...

Open AccessTrisomy 19 ependymoma, a newly recognized genetico-histological association, including clear cell ependymoma
Ependymal tumors constitute a clinicopathologically heterogeneous group of brain tumors. They vary in regard to their age at first symptom, localization, morphology and prognosis. Genetic data also suggests he...

Retargetable Code Generation : Key Issues for Successful Introduction
This chapter considers a number of major issues that a telecom system house like Alcatel faces as a result of the trend towards DSP systems-on-chip using DSP-cores : the choice of the DSP-core architecture, th...
