Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Alloesthesia is a rare clinical condition that corresponds to a spatial disorder of stimulus localization, in which patients experience a given stimulus on the side opposite to the side of stimulation. Whereas it has been mostly described for unisensory st ...
Homologues of Gpi8p, Gaa1p, Gpi16p, Gpi17p, and Cdc91p are essential components of the GPI transamidase complex that adds glycosylphosphatidylinositols (GPIs 1) to newly synthesized proteins in the ER. In mammalian cells, these five subunits remain stably ...
The resonant Rayleigh scattering dynamics of excitons in single GaAs quantum wells is investigated. The deviation of the measured intensity from the ideal ensemble average is analyzed as a function of the speckle ensemble size. The influence of the amplitu ...
A combined theoretical and experimental analysis of the resonant Rayleigh scattering by excitons in a disordered GaAs quantum well with monolayer islands is reported. Experimentally, the coherent resonant Rayleigh scattering is deduced by means of both sta ...

The response of total (DNA-based analysis) and active (RNA-based analysis) bacterial communities to a pCO2 increase under field conditions was assessed using two perennial grasses: the nitrophilic Lolium perenne and the oligonitrophilic Molinia coerulea. P ...
The spectral autocorrelation for a set of over 400 near-field photoluminescence spectra of a narrow quantum well has been evaluated. It is compared with a microscopic model of an exciton in a disorder potential. The analysis provides strong evidence for qu ...
We have investigated the doping mechanism of pentacene with iodine and its impact on the structure and on the electronic properties of single crystals, powders, and thin films in a large range of iodine concentration up to six iodine per pentacene (PEN) mo ...
The dynamics of resonant Rayleigh scattering (RRS) from excitons localized in a disorder potential with large monolayer islands is investigated theoretically and experimentally. Experimentally, the coherent RRS dynamics from GaAs single quantum wells (SQWs ...
With specially designed micromechanical cantilevers we have measured the magnetization of two-dimensional electron systems formed in an integrated single-layered AlGaAs/GaAs heterojunction. In samples of different mobility we have observed sawtooth-like de ...
V groove GaAs/AlGaAs quantum wires are investigated by spatially resolved photoluminescence spectroscopy using a low-temperature scanning near- field optical microscope. The spectra along the wires feature several sharp emission lines, which are understood ...
