Washington photometry of candidate star clusters in the Small Magellanic Cloud
(2012) [Artigo de periódico]We present for the first time Washington CT1 photometry for 11 unstudied or poorly studied candidate star clusters. The selected objects are of small angular size, contain a handful of stars, and are projected towards the ... -
Water diffusion in carbon nanotubes : Interplay between confinement, surface deformation, and temperature
(2020) [Artigo de periódico]In this article, we investigate, through molecular dynamics simulations, the diffusion behavior of the TIP4P/2005 water confined in pristine and deformed carbon nanotubes (armchair and zigzag). To analyze different diffusive ... -
Water diffusion in rough carbon nanotubes
(2020) [Artigo de periódico]We use molecular dynamics simulations to study the diffusion of water inside deformed carbon nanotubes with different degrees of deformation at 300 K. We found that the number of hydrogen bonds that water forms depends on ... -
Water in soybean oil microemulsions as medium for electrochemical measurements
(2003) [Artigo de periódico]Microemulsões de água em óleo de soja (w/o ME) foram preparadas com dodecil sulfato de sódio (SDS) como surfactante e com os álcoois amílico ou isoamílico, como co-surfactantes. A composição 40,0% de óleo, 43,2% de álcool, ... -
Waterlike anomalies in a two-dimensional core-softened potential
(2018) [Artigo de periódico]We investigate the structural, thermodynamic, and dynamic behavior of a two-dimensional (2D) core-corona system using Langevin dynamics simulations. The particles are modeled by employing a core-softened potential which ... -
Waterlike hierarchy of anomalies in continuous spherical shouldered potential
(2008) [Artigo de periódico]We investigate by molecular dynamics simulations a continuous isotropic core-softened potential with attractive well in three dimensions, introduced by Franzese [J. Mol. Liq. 136, 267 (2007)], that displays liquid-liquid ... -

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 ... -

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 ... -
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, ... -
W±-boson production in p–Pb collisions at √sNN = 8.16 TeV and Pb–Pb collisions at √sNN = 5.02 TeV
(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 ... -
