Probing the age and structure of the nearby very young open clusters NGC2244 and 2239
(2009) [Artigo de periódico]The very young open cluster (OC) NGC2244 in the Rosette Nebula was studied with fieldstar- decontaminated Two-Micron All-Sky Survey (2MASS) photometry, which shows the main-sequence (MS) stars and an abundant pre-MS (PMS) ... -
Probing the circumnuclear stellar populations of Starburst galaxies in the near-infrared
(2014) [Artigo de periódico]We employ the NASA Infrared Telescope Facility’s near-infrared spectrograph SpeX at 0.8– 2.4 μm to investigate the spatial distribution of the stellar populations (SPs) in the four well-known starburst galaxies: NGC 34, ... -
Probing the effects of strong electromagnetic fields with charge-dependent directed flow in Pb-Pb collisions at the LHC
(2020) [Artigo de periódico]The first measurement at the LHC of charge-dependent directed flow (v1) relative to the spectator plane is presented for Pb-Pb collisions at √sNN=5.02 TeV. Results are reported for charged hadrons and D0 mesons for the ... -
Probing the internal rotation of pre-white dwarf stars with asteroseismology : the case of PG 0122+200
(2011) [Artigo de periódico]We put asteroseismological constraints on the internal rotation profile of theGWVir (PG1159- type) star PG 0122+200. To this end we employ a state-of-the-art asteroseismological model for this star and assess the expected ... -
Probing the Large Magellanic Cloud age gap at intermediate cluster masses
(2010) [Artigo de periódico]The Large Magellanic Cloud (LMC) has a rich star cluster system spanning a wide range of ages and masses. One striking feature of the LMC cluster system is the existence of an age gap between 3 and 10 Gyr. But this feature ... -
Probing the near-infrared stellar population of Seyfert galaxies
(2009) [Artigo de periódico]We employ Infrared Telescope Facility SpeX near-infrared (NIR; 0.8–2.4 μm) spectra to investigate the stellar population (SP), active galactic nuclei (AGN) featureless continuum (FC) and hot dust properties in nine Sy 1 ... -
Probing the reciprocal lattice associated with a triangular slit to determine the orbital angular momentum for a photon
(2020) [Artigo de periódico]The orbital angular momentum conservation of light reveals different diffraction patterns univocally dependent on the topological charge of the incident light beam when passing through a triangular aperture. It is demonstrated ... -
Probing thermomechanical behavior of polymers at the nanometer scale with single-ion bombardment and scanning force microscopy
(2000) [Artigo de periódico]Features produced by swift heavy ions on polymer thin films at different temperatures are used to identify the transition between vitreous and viscoelastic behaviors (the glass transition temperature) and to probe the ... -
Probing the spin-orbit coupling of nuclear protons
(1973) [Artigo de periódico]The strong absorption in quasi-free scattering opens a possibility of measuring the spin-orbit coupling of nuclear protons. Cross sections for polarized incoming protons are expected to exhibit pronounced asymmetries, with ... -
Probing the structure of Kepler ZZ Ceti stars with full evolutionary models-based asteroseismology
(2017) [Artigo de periódico]We present an asteroseismological analysis of four ZZ Ceti stars observed with the Kepler spacecraft: GD 1212, SDSS J113655.17+040952.6, KIC 11911480, and KIC 4552982, based on a grid of full evolutionary models of DA white ... -
Probing the symmetry energy from the nuclear isoscaling
(2008) [Artigo de periódico]Using different parametrizations of the nuclear mass formula, we study the sensitivity of the isoscaling parameters to the mass formula employed in grand-canonical calculations. Previous works on isoscaling have suggested ... -
Probing tumor aggressiveness via image analysis
(2021) [Dissertação]Cancer is the second leading cause of death worldwide. In this disease, tumor cells have to invade and migrate through various complex structures of the body. It is well-accepted that the physics underlying tissue dynamics ... -
Probing underlying mechanisms for PCBN tool decay during friction stir welding of nickel-based alloys
(2021) [Artigo de periódico]Friction stir welding (FSW) of nickel-based alloys can provide joints with improved corrosion resistance and mechanical properties that are deteriorated significantly during fusion welding of these alloys. However, rapid ... -
Probiótico LAB18S: um estudo genômico, proteômico e das interações com os prebióticos e com o microbioma intestinal humano
(2020) [Tese]A microbiota intestinal exerce um papel fundamental na saúde humana e o aumento de evidências apoia o papel benéfico dos microrganismos probióticos na manutenção da saúde intestinal. Neste estudo foram abordados estudos ... -
