The metallicity gradients of star-forming regions store information of the assembly history of galaxies [PDF]

Monthly notices of the Royal Astronomical Society
The variations in metallicity and spatial patterns within star-forming regions of galaxies result from diverse physical processes unfolding throughout their evolutionary history, with a particular emphasis on recent events.

Observable for a Large System of Globally Coupled Excitable Units

Mathematical and Computational Applications, 2019
The study of large arrays of coupled excitable systems has largely benefited from a technique proposed by Ott and Antonsen, which results in a low dimensional system of equations for the system’s order parameter.

Factors underlying bird community assembly in anthropogenic habitats depend on the biome

Scientific Reports, 2022
Production activities drive the replacement of original habitats with artificial ones, leading to new bird assemblages. In this study, we assessed if anthropogenic habitats acted as environmental filters causing functional redundancy or as promoters of ...

Interference conditions of the reconsolidation process in humans: the role of valence and different memory systems.

Frontiers in Human Neuroscience, 2016
Following the presentation of a reminder, consolidated memories become reactivated followed by a process of re-stabilization, which is referred to as reconsolidation. The most common behavioral tool used to reveal this process is interference produced by
