Weighted estimates for solutions of the -equation for lineally convex domains of finite type and applications to weighted bergman projections
In this paper we obtain sharp weighted estimates for solutions of the
-equation in a lineally convex domains of finite type. Precisely we
obtain estimates in spaces of the form L p ({\Omega}, ),
being the distance to the boundary, with gain on the index p and the
exponent . These estimates allow us to extend the L p
({\Omega}, ) and lipschitz regularity results for weighted
Bergman projection obtained in [CDM14b] for convex domains to more general
weights
Chaos, Coherence and the Double-Slit Experiment
We investigate the influence that classical dynamics has on interference
patterns in coherence experiments. We calculate the time-integrated probability
current through an absorbing screen and the conductance through a doubly
connected ballistic cavity, both in an Aharonov-Bohm geometry with forward
scattering only. We show how interference fringes in the probability current
generically disappear in the case of a chaotic system with small openings, and
how they may persist in the case of an integrable cavity. Simultaneously, the
typical, sample dependent amplitude of the flux-sensitive part of the
conductance survives in all cases, and becomes universal in the case of a
chaotic cavity. In presence of dephasing by fluctuations of the electric
potential in one arm of the Aharonov-Bohm loop, we find an exponential damping
of the flux-dependent part of the conductance, , in term of the traversal time through the arm
and the dephasing time . This extends previous works on dephasing in
ballistic systems to the case of many conducting channels.Comment: 8 pages, 4 figures in .eps format; Final version, to appear in
Physical Review
A stationary free boundary problem modeling electrostatic MEMS
A free boundary problem describing small deformations in a membrane based
model of electrostatically actuated MEMS is investigated. The existence of
stationary solutions is established for small voltage values. A justification
of the widely studied narrow-gap model is given by showing that steady state
solutions of the free boundary problem converge toward stationary solutions of
the narrow-gap model when the aspect ratio of the device tends to zero
Deposition of La2Zr2O7 Film by Chemical Solution Deposition
La2Zr2O7 (LZO) formation of bulk powders and of films by Chemical Solution
Deposition (CSD) process have been studied using propionates. The treatment
involved a one step cycle in the reducing forming gas (Ar-5%H2) to be
compatible with Ni-5at%W RABITS. Large amount of residual carbon was found in
LZO powders formed in these conditions (10 wt %). The volume fraction of the
cube texture in LZO films on Ni-5at%w RABITS was found to be a function of the
speed of the gas flown above sample. This phenomenon is discussed in
considering the C deposited from the carbon-containing gases emitted during the
pyrolysis of the precursor. Using proper conditions (950 ^\circC and the speed
of gas of 6.8\times10^{-2} m/s), LZO films with good surface crystallinity
could be obtained on Ni-5at%W RABITS as demonstrated by X-ray diffraction,
electron backscattered diffraction and RHEED. The existence of residual carbon
in oxide films is a common question to films deposited by CSD processes under
reducing condition

La valorisation du sang d'abattoirs en Belgique.
peer reviewedCet article comprend une analyse sommaire des possibilités de valorisation du sang recueilli dans les abattoirs d'animaux de boucherie. Après un bref exposé sur la législation belge en la matière et sur les techniques qui permettent un traitement du sang, les auteurs ont estimé les quantités produites au départ des abattoirs belges et qualifié le réseau de collecte en Wallonie
