Water vapor interaction with silicon oxide films thermally grown on 6H-SiC and Si
(2009) [Artigo de periódico]Thermally induced incorporation of isotopically labeled water vapor D2 18O species in 7 nm thick SiO2 films thermally grown on 6H-SiC 0001 and on Si 001 were investigated. Higher incorporation of hydrogen and higher isotopic ... -
Water wave radiation by a heaving submerged horizontal disk very near the free surface
(2010) [Artigo de periódico]The radiation of water waves by heaving horizontal disk at a shallow submergence depth is considered. The problem is formulated as a Fredholm integral equation. The resonant frequencies originating from the shallow submergence ... -
Wave breaking and particle jets in intense inhomogeneous charged beams
(2007) [Artigo de periódico]This work analyzes the dynamics of inhomogeneous, magnetically focused high-intensity beams of charged particles. While for homogeneous beams the whole system oscillates with a single frequency, any inhomogeneity leads to ... -

Wave length and celerity downstream from a hydraulic jump
(2019) [Artigo de periódico]It allows the estimation of other important wave characteristics such as the length and celerity. This study aims at describing the results of a relationship among the significant, mean, and peak periods of waves generated ... -
Wavelength self-calibration and sky subtraction for Fabry-Pérot interferometers : applications to OSIRIS
(2015) [Artigo de periódico]We describe techniques concerning wavelength calibration and sky subtraction to maximize the scientific utility of data from tunable filter instruments. While we specifically address data from the Optical System for Imaging ... -
A wavelet-based approach for analyzing industrial stochastic textures with applications
(2007) [Artigo de periódico]Several continuous manufacturing processes use stochastic texture images for quality control and monitoring. Large amounts of pictorial data are acquired, providing important information about both the materials produced ... -
WaveMIMO methodology : numerical wave generation of a realistic sea state
(2021) [Artigo de periódico]This paper presents a methodology that allows the numerical simulation of realistic sea waves, called WaveMIMO methodology, which is based on the imposition of transient discrete data as prescribed velocity on a finite ... -
Waves in magnetized dusty plasmas with variable charge on dust particles
(2004) [Artigo de periódico]We present results obtained in recent years for wave propagation in a magnetized dusty plasma, including variable charge of the dust particles, and using a kinetic approach. Two forms of the dielectric tensor are obtained, ... -

(2023) [Artigo de periódico]The production of the W± bosons measured in p–Pb collisions at a centre of-mass energy per nucleon–nucleon collision √sNN = 8.16 TeV and Pb–Pb collisions at √sNN = 5.02 TeV with ALICE at the LHC is presented. The W± bosons ... -
Weak and strong coupling theories for polarizable colloids and nanoparticles
(2011) [Artigo de periódico]A theory is presented which allows us to accurately calculate the density profile of monovalent and multivalent counterions in suspensions of polarizable colloids or nanoparticles. In the case of monovalent ions, we derive ... -
Weak instability of frustated fermionic models
(1997) [Artigo de periódico]We study the Almeida-Thouless instability of two fermionic models analogous to spin glasses that exhibit frustration and that were solved some time ago with a replica symmetric ansatz. In the first model (I) we consider ... -
Weak lensing and spectroscopic analysis of the nearby dissociative merging galaxy cluster Abell 3376
(2017) [Artigo de periódico]The galaxy cluster Abell 3376 is a nearby (¯z = 0.046) dissociative merging cluster surrounded by two prominent radio relics and showing an X-ray comet-like morphology. The merger system is comprised of the subclusters ... -

(2016) [Artigo de periódico]The dynamics of linear and nonlinear ionic-scale electrostatic excitations propagating in a magnetized relativistic quantum plasma is studied. A quantum-hydrodynamic model is adopted and degenerate statistics for the ... -
Weakly turbulent plasma processes in the presence of inverse power-law velocity tail population
(2017) [Artigo de periódico]Observations show that plasma particles in the solar wind frequently display power-law velocity distributions, which can be isotropic or anisotropic. Particularly, the velocity distribution functions of solar wind electrons ... -
Weak solutions for the electrophoretic motion of charged particles
(2006) [Artigo de periódico]We introduce a weak formulation for a system of electrostatic and hydrodynamic equations modelling the electrophoretic motion of charged particles in ionized fluids. We obtain a local in time existence theorem, using the ... -
Weak turbulence in dusty plasmas with collisional dust charging : quasilinear wave-particle interaction
(2015) [Artigo de periódico]Starting from the exact microscopic equations for an unmagnetized dusty plasma, where the dust charge is regarded as a new degree of freedom of the system, we present a self-consistent set of equations that is suitable for ... -
Weak turbulence theory for collisional plasmas
(2016) [Artigo de periódico]Plasma is an ionized gas inwhich the collective behavior dominates over the individual particle interactions. For this reason, plasma is often treated as collisionless or collision-free. However, the discrete nature of the ... -
Weaning from mechanical ventilation in ARDS : aspects to think about for better understanding, evaluation, and management
