Global existence and uniqueness for the Lake equations with vanishing topography : elliptic estimates for degenerate equations
Bresch Didier, Guy Metivier
This paper deals with global existence and uniqueness for the lake equations with a bottom topography vanishing on the shore. Our result generalizes previous studies that assumed t…
Infrared and THz studies of polar phonons and improper magnetodielectric effect in multiferroic BFO3 ceramics
S. Kamba, D. Nuzhnyy, M. Savinov +5
BFO3 ceramics were investigated by means of infrared reflectivity and time domain THz transmission spectroscopy at temperatures 20 - 950 K, and the magnetodielectric effect was stu…
Which jet launching mechanism(s) in TTauri stars?
Jonathan Ferreira, Catherine Dougados, Sylvie Cabrit
AIMS: We examine whether ejection phenomena from accreting T Tauri stars can be described by only one type of self-collimated jet model. METHODS: We present analytical kinematic pr…
Archeops In-flight Performance, Data Processing and Map Making
J. F. Macias-Perez, G. Lagache, B. Maffei +69
Archeops is a balloon--borne experiment widely inspired by the Planck satellite and by its High Frequency Instrument (HFI). It is mainly dedicated to measure the Cosmic Microwave B…
EXAFS study of lead-free relaxor ferroelectric BaTi(1-x)Zr(x)O3 at the Zr K-edge
C. Laulhe, F. Hippert, J. Kreisel +4
Extended X-ray absorption fine structure (EXAFS) experiments at the Zr K-edge were carried out on perovskite relaxor ferroelectrics BaTi(1-x)Zr(x)O3 (BTZ) (x = 0.25, 0.30, 0.35), a…
