Bird-window collisions: A comprehensive dataset for the Neotropical region. [PDF]

open access: yesEcology
Abstract Our primary objective was to compile a comprehensive dataset on bird–window collisions throughout the Neotropical region, including both published and unpublished sources. On May 12, 2020, we extensively disseminated invitations to provide data via email and social media platforms.

Prospective Longitudinal Cohort of Argentinean Patients with Progressive Supranuclear Palsy: A Platform for Epidemiological and Translational Research [PDF]

open access: yesAlzheimers Dement
Abstract Background Progressive supranuclear palsy (PSP) and corticobasal syndrome (CBS) are two neurodegenerative disorders that manifest disabling postural instability, parkinsonism, cognitive impairment and falls with brain neurofibrillary tangle lesions containing 4‐repeat tau protein. The prevalence is 6/100,000 inhabitants but estimated only from

Eleven‐Year Survey of the Magmatic‐Hydrothermal Fluids From Peteroa Volcano: Identifying Precursory Signals of the 2018–2019 Eruption

open access: yesGeochemistry, Geophysics, Geosystems, Volume 24, Issue 11, November 2023., 2023
Abstract Over the past decade, we have conducted geochemical and isotopic monitoring of the fumarolic gases of the Peteroa volcano (Argentina‐Chile). Using the resulting data set, we constructed a conceptual model that describes the evolution of the magmatic‐hydrothermal system and identifies precursory geochemical signals of the last eruption.

The Coexistence of Gravity Waves From Diverse Sources During a SOUTHTRAC Flight

open access: yesJournal of Geophysical Research: Atmospheres, Volume 128, Issue 5, 16 March 2023., 2023
Abstract We use observations from one of the SOUTHTRAC (Southern Hemisphere Transport, Dynamics, and Chemistry) Campaign flights in Patagonia and the Antarctic Peninsula during September 2019 to analyze possible sources of gravity waves (GW) in this hotspot during austral late winter and early spring. Data from two of the instruments onboard the German

A BCS microwave imaging algorithm for object detection and shape reconstruction tested with experimental data

open access: yesElectronics Letters, Volume 57, Issue 2, Page 88-91, January 2021., 2021
Abstract An approach based on the Green function and the Born approximation is used for impulsive radio ultra‐wideband microwave imaging, in which a permittivity map of the illuminated scenario is estimated using the scattered fields measured at several positions. Two algorithms are applied to this model and compared: the first one solves the inversion

Metapopulation dynamics and foraging plasticity in a highly vagile seabird, the southern rockhopper penguin

open access: yesEcology and Evolution, Volume 10, Issue 7, Page 3346-3355, April 2020., 2020
With the use of genomic and stable isotopes techniques, we provide new insights on the relationship between the use of different foraging grounds and dispersal‐driven population connectivity in a seabird species. We discover two recently isolated lineages within this species presenting different foraging and dispersal behavior.

A 3‐Year Sample of Almost 1,600 Elves Recorded Above South America by the Pierre Auger Cosmic‐Ray Observatory

open access: yesEarth and Space Science, Volume 7, Issue 4, April 2020., 2020
Abstract Elves are a class of transient luminous events, with a radial extent typically greater than 250 km, that occur in the lower ionosphere above strong electrical storms. We report the observation of 1,598 elves, from 2014 to 2016, recorded with unprecedented time resolution (100 ns) using the fluorescence detector (FD) of the Pierre Auger Cosmic ...

Eficiencia en la retención del agua de lluvia de cubiertas vegetadas de tipo "extensivo" e "intensivo" *

open access: yesRevista de la Facultad de Ciencias Agrarias, 2022
La inundación en áreas urbanas por sobrecarga de las redes de drenaje es un problema recurrente de importancia creciente. Las cubiertas vegetadas (naturadas) retienen parte de la lámina de agua precipitada, reduciendo el escurrimiento superficial y ...
