Measurement of the cosmic ray spectrum above $4{\times}10^{18}$ eV using inclined events detected with the Pierre Auger Observatory

open access: yes, 2015
A measurement of the cosmic-ray spectrum for energies exceeding $4{\times}10^{18}$ eV is presented, which is based on the analysis of showers with zenith angles greater than $60^{\circ}$ detected with the Pierre Auger Observatory between 1 January 2004 ...

Calibration of the Logarithmic-Periodic Dipole Antenna (LPDA) Radio Stations at the Pierre Auger Observatory using an Octocopter [PDF]

open access: yes, 2017
An in-situ calibration of a logarithmic periodic dipole antenna with a frequency coverage of 30 MHz to 80 MHz is performed. Such antennas are part of a radio station system used for detection of cosmic ray induced air showers at the Engineering Radio ...

Transcriptomic Divergence and Associated Markers Between Genomic Lineages of Silver Catfish (Rhamdia quelen)

open access: yesEcology and Evolution, Volume 15, Issue 3, March 2025.
We present transcriptomic divergence between two latitudinally distributed lineages of Rhamdia quelen, which could explain local adaptations and the speciation processes proposed in previous studies. Moreover, the differentiation of transposable elements between lineages could also be associated with this speciation process.

DINÁMICA DE CLUSTERS DE VACANCIAS EN SILICIO

open access: yesAnales (Asociación Física Argentina), 2007
Se estudia la dinámica de aglomerados de vacancias en Silicio utilizando un modelo computacional en la aproximación del continuo. El modelo considera que las vacancias, generadas por activación térmica o por irradiación, pueden difundir y agruparse ...

Sites for Gamma-ray Astronomy in Argentina

open access: yes, 2008
We have searched for possible sites in Argentina for the installation of large air Cherenkov telescope arrays and water Cherenkov systems. At present seven candidates are identified at altitudes from 2500 to 4500 m.

Polycaprolactone/MSMA composites for magnetic refrigeration applications

open access: yesPolymer Composites, Volume 46, Issue 1, Page 427-437, 10 January 2025.
PCL/Ni‐Mn‐In‐Co printable composites are promising candidates for development of high surface/volume ratio heat exchangers for magnetic refrigeration applications. Abstract A high filling load (62% weight) printable magnetic composite has been elaborated from the dispersion of magnetocaloric Ni45Mn36.7In13.3Co5 metamagnetic shape memory alloy ...

Inferring single neuron properties in conductance-based balanced networks

open access: yesFrontiers in Computational Neuroscience, 2011
Balanced states in large networks are a usual hypothesis for explaining the variability of neural activity in cortical systems. These states give rise to a generic behavior in which the individual dynamics of the neurons is almost irrelevant.
