Mixing and Geometry in the North Atlantic Meridional Overturning Circulation

open access: yesGeophysical Research Letters, Volume 50, Issue 7, 16 April 2023., 2023
Abstract Vertical motions across the ocean are central to processes, like CO2 fixation, heat removal or pollutant transport, which are essential to the Earth's climate. This work explores 3D conveyor routes associated with the Atlantic Meridional Overturning Circulation (AMOC).

Large-signal theory of the effect of dispersive propagation on the intensity modulation response of semiconductor lasers [PDF]

open access: yes, 2000
We have derived an exact large-signal theory of propagation in a dispersive fiber of an optical wave with sinusoidal amplitude and frequency modulation. This has been applied to the study of large-signal direct-modulation of semiconductor lasers.

The life journey of Greeks in Ingeniero White, Argentina

open access: yes, 2021
Para analizar la identidad de una colectividad griega en Argentina, no podemos evitar usar una metáfora de origen clásico. Si bien en un inicio el migrante sigue una vida de viaje como Ulises, termina siendo más como un viaje de vida, como Alejandro. En el presente artículo realizado a partir de un trabajo etnogeográfico, se estudia la composición de ...

Elevation, rather than land use, causes important dietary shifts in the Mediterranean golden eagle

open access: yesJournal of Zoology, EarlyView.
In an ever‐changing landscape, golden eagles in the Iberian Peninsula demonstrate remarkable dietary adaptability. We monitored 50 distinct breeding events over 4 years using camera traps, collecting over 520 000 images. Elevation, rather than land use, emerged as the main driver of prey composition: lagomorphs and columbiforms dominated at lower ...
