Two new pulsating low-mass pre-white dwarfs or SX Phoenicis stars?
(2016) [Artículo de periódico]Context. The discovery of pulsations in low-mass stars opens an opportunity to probe their interiors and determine their evolution by employing the tools of asteroseismology. Aims. We aim to analyse high-speed photometry ... -
Two new species of Odontostilbe historically hidden under O. microcephala (Characiformes: Cheirodontinae)
(2018) [Artículo de periódico]Specimens historically identified as Odontostilbe microcephala from the upper rio Paraná and Andean piedmont tributaries of the río Paraguay are reviewed and split in three species. We found that the distribution of O. ... -
Two new troglobitic species of Scleropactidae (Crustacea: Isopoda: Oniscidea) from Pará, Brazil
(2011) [Artículo de periódico]The South America Scleropactidae includes 53 nominal species distributed in 14 genera. In Brazil, there are 16 species recorded in the north and southeast regions. Here, two new species of Scleropactidae are described based ... -
Two-particle azimuthal correlations in γp interactions using pPb collisions at √sNN = 8.16 TeV
(2023) [Artículo de periódico]The first measurements of the Fourier coefficients (Vn) of the azimuthal distributions of charged hadrons emitted from photon-proton (γp) interactions are presented. The data are extracted from 68.8 nb−1 of ultra-peripheral ... -
Two-particle differential transverse momentum and number density correlations in p−Pb collisions at 5.02 TeV and Pb-Pb collisions at 2.76 TeV at the CERN Large Hadron Collider
(2019) [Artículo de periódico]We present measurements of two-particle differential number correlation functionsR2and transverse momen-tum correlation functionsP2, obtained fromp-Pb collisions at 5.02 TeV and Pb-Pb collisions at 2.76 TeV. Theresults are ... -
Two-particle transverse momentum correlations in pp and p-Pb collisions at energies available at the CERN Large Hadron Collider
(2023) [Artículo de periódico]Two-particle transverse momentum differential correlators, recently measured in Pb-Pb collisions at energies available at the CERN Large Hadron Collider (LHC), provide an additional tool to gain insights into particle ... -
Two-pass friction stir welding of cladded API X65
(2020) [Artículo de periódico]Cladded materials are used by the oil and gas industry due to the combination of good mechanical properties and low cost of high-strength low-alloy steel (HSLA) API 5L X65 with the excellent corrosion resistance of the ... -
Two-phase flow (water-air) analysis in a dispersed bubbles regimes

Two reddened globular cluster projected close to the galactic center : Palomar 6 and Djorgovski 1
(1995) [Artículo de periódico]We present NTT V,I observations of Palomar 6 and Djorgovski 1, two obscured loose clusters in crowded fields. We derive a reddening of E(B - V) = 1.33 ± 0.10, a distance dʘ ≈ 8.9 kpc, and a metallicity of [Fe/H] ≈ -0.4 for ... -
Two rubber balloons : phase diagram of air transfer
(2004) [Artículo de periódico]Two identical rubber balloons are partially inflated with air (to different extent) and connected by a hose with a valve. It is found that depending on initial balloon volumes, when the valve is opened the air will flow ... -
Two scenarios for superconductivity in CeRh2As2
(2021) [Artículo de periódico]CeRh2As2, a nonsymmorphic heavy fermion material, was recently reported to host a remarkable temperature versus z-axis magnetic-field phase diagram with two superconducting phases. In this material, the two inequivalent ... -
Two serendipitous low-mass lmc dusters discovered with hst
(1998) [Artículo de periódico]We present V and I photometry of two open clusters in the LMC down to V~26. The clusters were imaged with the Wide Field and Planetary Camera 2 (WFPC2) on board the Hubble Space Telescope (HST), as part of the Medium Deep ... -
A two-sided method for nonlinear equations with cubic convergence
(1989) [Artículo de periódico]A two-sided method for finding a zero of 'a real-valued function on a given interval is presented and its convergence features are analysed, This method combines ih a simple way the well known schemes of Newton Raphson and ... -
Two-site Bose-Hubbard model with nonlinear tunneling : classical and quantum analysis
(2017) [Artículo de periódico]The extended Bose-Hubbard model for a double-well potential with atom-pair tunneling is studied. Starting with a classical analysis we determine the existence of three quantum phases: self-trapping, phase-locking, and ... -
Two-step continuous cooling heat treatment applied in a low carbon bainitic steel
(2021) [Artículo de periódico]Thermo-mechanical treatments using continuous cooling after forging are an established method for producing bainitic steels, mainly because of the elimination of energy intensive additional heat treatment processes. The ... -
Two-step purification and partial characterization of keratinolytic proteases from feather meal bioconversion by Bacillus sp. P45
(2023) [Artículo de periódico]This study aimed to purify and partially characterize a keratinolytic protease produced by Bacillus sp. P45 through bioconversion of feather meal. Crude protease extract was purified using a sequence of an aqueous two-phase ... -
A two-step workflow based on plasma p-tau217 to screen for amyloid β positivity with further confirmatory testing only in uncertain cases
(2023) [Artículo de periódico]Cost-effective strategies for identifying amyloid-β (Aβ) positivity in patients with cognitive impairment are urgently needed with recent approvals of anti-Aβ immunotherapies for Alzheimer’s disease (AD). Blood biomarkers ... -
