Assessment of structural evolution of aggregated soil using neutron tomography

Lyesse Laloui, Laurent Vulliet, Azad Koliji

The advanced non-destructive method of neutron tomography, together with image analysis, is used to evaluate the structural evolution of an aggregated soil during one-dimensional compression tests. Aggregation of primary particles is a commonly observed ph ...

Microlensing variability in the gravitationally lensed quasar QSO 2237+0305 equivalent to the Einstein Cross II. Energy profile of the accretion disk

Frédéric Courbin, Georges Meylan, Alexander Patrick Eigenbrod

We present the continuation of our long-term spectroscopic monitoring of the gravitationally lensed quasar QSO 2237 + 0305. We investigate the chromatic variations observed in the UV/optical continuum of both quasar images A and B, and compare them with nu ...

A Probabilistic Model for Chord Progressions

Samy Bengio, Jean-François Paiement

Chord progressions are the building blocks from which tonal music is constructed. Inferring chord progressions is thus an essential step towards modeling long term dependencies in music. In this paper, a distributed representation for chords is designed su ...

Chord Representations for Probabilistic Models

Samy Bengio, Jean-François Paiement

Chord progressions are the building blocks from which tonal music is constructed. Inferring chord progressions is thus an essential step towards modeling long term dependencies in music. In this paper, three different representations for chords are designe ...

Charge transfer excitations of doped rare gas matrixes

Majed Chergui

Structured progressions, assocd. with the Cl-Rg+ and H-Rg+ charge transfer species, are obsd. for Cl and H atoms isolated in Kr and Xe (Rg) crystals and are assigned as transitions to Rydberg states. The Rydberg levels correspond to delocalized pos. hole s ...

Observation of the Rydberg states of nitric oxide trapped in an argon matrix

Majed Chergui

Three new progressions consisting of broad bands (full width at half max. .simeq. 130 meV) were obsd. in the absorption spectrum of NO trapped in an Ar matrix. A Wannier model fails to describe these transitions; they are identified as the mol. Rydberg tra ...

Rydberg states and intramolecular relaxation of nitric oxide trapped in rare gas matrixes

Majed Chergui

Three new progressions consisting of broad bands were obsd. in the absorption spectrum of NO in solid Ar. They are identified as the mol. Rydberg A 2.sum.+,C 2P and D 2.sum.+-X 2P (v', 0) transitions, blue shifted with respect to the gas phase by .apprx.0. ...
