Aluminum nitride thin films have been grown by reactive magnetron sputter technique using a pulsed power supply. The highly (002)-textured columnar films deposited on platinized silicon substrates exhibited quasi-single-crystal piezoelectric properties. Th ...
The ultrafast dynamics of electronic bubble formation upon excitation of the A(3ss) Rydberg state of NO trapped in solid H2 and D2 was studied by femtosecond pump-probe spectroscopy. The evolution of the spherical bubble is followed in real time by a probe ...
We report on structural dynamics in simple van der Waals solids (Ar, Ne, and H2), as driven by the excitation of an impurity (NO) Rydberg state. The resulting charge redistribution induces a local radial deformation of the medium ("bubble" formation). Th ...
A sound that we hear in a natural setting allows us to identify the sound source and localize it in space. The two aspects can be disrupted independently as shown in a study of 15 patients with focal right-hemispheric lesions. Four patients were normal in ...
In this paper, we study the spatialization of the sound field in rooms, in particular the evolution of the room impulse responses in function of their spatial positions. Thanks to this study, we are now able to predict the sound field in any position knowi ...
Inline conversion measurements in chem. reactions are in general and esp. in polymn. reactions necessary for process monitoring and control. For polymn. monitoring, the sound propagation (UPV) can be related to the texture of the bulk with a high accuracy. ...
It is shown that low n, pressure-driven, external modes in tokamaks can be fully stabilized by resistive walls when the plasma rotates at some fraction of the sound speed. The stabilization depends on toroidal coupling to sound waves and is affected by ion ...
We present a method for generating conversations between human-like agents by proposing specific parameters for inter-agents messages with an approximation of virtual sound propagation. We are then be able to simulate appropriate human-like behaviours auto ...
The acoustic phonon dispersion curves of the hexagonal perovskite CsNiCl3 were measured at room temperature in the vicinity of the Gamma-point along the [0 0 1] and [1 1 0] directions. The derived velocity of sound values for the longitudinal and transvers ...
Thermomechanical modeling of a sample assembly (sample plus pressure transmitting medium) in a laser-heated diamond-anvil cell (LHDAC) is presented. Finite elements numerical calculation afforded to obtain the temperature distribution and the induced therm ...
