Measurements of the neutron absorption in supermirror coatings
D. D. DiJulio, V. Santoro, A. Devishvili +5
In this work we report on measurements of neutron absorption in supermirror coatings. The measurements were carried out using the SuperADAM instrument at the Institut Laue-Langevin…
Diffuse field cross-correlations: scattering theory and electromagnetic experiments
Matthieu Davy, Philippe Besnier, Philipp del Hougne +7
The passive estimation of impulse responses from ambient noise correlations arouses increasing interest in seismology, acoustics, optics and electromagnetism. Assuming the equipart…
Partial-Field Illumination Ophthalmoscope: improving the contrast of a camera-based retinal imager
Léa Krafft, Elena Gofas-Salas, Yann Lai-Tim +5
Effective and accurate in-vivo diagnosis of retinal pathologies requires high performance imaging devices, combining a large field of view and the ability to discriminate the balli…
Polarized neutron scattering studies of magnetic excitations in iron-selenide superconductor (LiFe)ODFeSe ( = 41 K)
Die Hu, Yu Feng, Jitae T. Park +5
We report polarized neutron scattering measurements of the low energy spin fluctuations of the iron-selenide superconductor LiFeODFeSe below and above its supercond…
Stability for finite element discretization of some elliptic inverse parameter problems from internal data -- application to elastography
Elie Bretin, Pierre Millien, Laurent Seppecher
In this article, we provide stability estimates for the finite element discretization of a class of inverse parameter problems of the form $-\nabla\cdot(μS) = \g f$ in a domain …
Non invasive live imaging of a novel retinal pigment epithelium stress model with Dynamic Full-Field Optical Coherence Tomography
Kassandra Groux, Anna Verschueren, Céline Nanteau +7
Retinal degenerative diseases lead to the blindness of millions of people around the world. In case of age-related macular degeneration (AMD), the atrophy of retinal pigment epithe…
