Molecular dating and diversification of the South American lizard genus Liolaemus (subgenus Eulaemus) based on nuclear and mitochondrial DNA sequences
(Oxford University Press, 2012-04)
The temperate South American lizard genus Liolaemus is the one of the most widely distributed and species-rich genera of lizards on earth. The genus is divided into two subgenera, Liolaemus sensu stricto (the 'Chilean ...
Auditory Distance Perception by Blind and Sighted Participants for Both Within and Beyond-Reach Sources
(American Psychological Association, 2022-05)
This study aimed to test the hypothesis that associates blindness with a reduced ability to judge the absolute distance from sound sources. Our working hypotheses were the following: (a) Within reach, a blind subject will ...
Land Intercalibration and Drift Monitoring of MWR Radiometer on Board SAC-D/Aquarius
(Institute Of Electrical And Electronics Engineers, 2015-06)
The microwave radiometer (MWR) on board the SAC-D/Aquarius mission is a Dicke radiometer operating at 23.8 (H-Pol) and 36.5 GHz (H/V-Pol), which can provide ancillary data for the various retrievals to be performed with ...
Gravity reference at the Argentinean–German Geodetic Observatory (AGGO) by co-location of superconducting and absolute gravity measurements
(Springer, 2020-11-25)
The Argentinean–German Geodetic Observatory (AGGO) is a fundamental geodetic observatory located close to the city of La Plata, Argentina. Two high-precision gravity meters are installed at AGGO: the superconducting ...
Using Proton Nuclear Magnetic Resonance (NMR) as a calibrating reference for magnetic field measurement instruments: Sensitive volume and magnetic field homogeneity
(Elsevier, 2020-02)
Nuclear magnetic resonance can be conveniently used to set up reference values of magnetic flux densities for the calibration of measurement instrumentation. Two measurement procedures are proposed based on the Fourier ...
The Comings and Goings of Sheep and Pottery in the Coastal Desert of Namaqualand, South Africa
(Taylor & Francis, 2018-03)
This paper evaluates chronological trends in the presence and absence of domestic animal bone (sheep, goat, and cattle) and pottery in Namaqualand, the proposed gateway to the rest of South Africa for early herders or ...
Electron and photon energy calibration with the ATLAS detector using LHC Run 1 data
(Springer, 2014-11)
This paper presents the electron and photon energy calibration achieved with the ATLAS detector using about 25 fb−1 of LHC proton?proton collision data taken at centre-of-mass energies of s√=7 and 8 TeV. The reconstruction ...
The fossil record of spiders revisited: implications for calibrating trees and evidence for a major faunal turnover since the Mesozoic
(Wiley Blackwell Publishing, Inc, 2020-02)
Studies in evolutionary biology and biogeography increasingly rely on the estimation of dated phylogenetic trees using molecular clocks. In turn, the calibration of such clocks is critically dependent on external evidence ...
A novel second-order standard addition analytical method based on data processing with multidimensional partial least-squares and residual bilinearization
(Elsevier Science, 2009-10)
In the presence of analyte-background interactions and a significant background signal, both second-order multivariate calibration and standard addition are required for successful analyte quantitation achieving the ...
Chemical abundances of Seyfert 2 AGNs, II: N2 metallicity calibration based on SDSS
(Wiley Blackwell Publishing, Inc, 2020-06)
We present a semi-empirical calibration between the metallicity (Z) of Seyfert 2 active galactic nuclei and the N2 = log([N II]λ6584/H a) emission-line intensity ratio. This calibration was derived through the [OIII]λ5007/[O ...
