An updated radiocarbon-based ice margin chronology for the last deglaciation of the North American Ice Sheet Complex

open access: yesQuaternary Science Reviews, 2020
The North American Ice Sheet Complex (NAISC; consisting of the Laurentide, Cordilleran and Innuitian ice sheets) was the largest ice mass to repeatedly grow and decay in the Northern Hemisphere during the Quaternary.

Constraining the Cratering Chronology of Vesta [PDF]

open access: yes, 2014
Vesta has a complex cratering history, with ancient terrains as well as recent large impacts that have led to regional resurfacing. Crater counts can help constrain the relative ages of different units on Vesta's surface, but converting those crater ...

High-resolution chronology for deglaciation of the Patagonian Ice Sheet at Lago Buenos Aires (46.5°S) revealed through varve chronology and Bayesian age modelling

open access: yesQuaternary Science Reviews, 2017
Glaciolacustrine varves offer the potential to construct continuous, annually-resolved chronologies for ice-sheet deglaciation, and improved understanding of glacier retreat dynamics. This paper investigates laminated glaciolacustrine sediments deposited

Texture-based brain networks for characterization of healthy subjects from MRI

open access: yesScientific Reports, 2023
Brain networks have been widely used to study the relationships between brain regions based on their dynamics using, e.g. fMRI or EEG, and to characterize their real physical connections using DTI.

Disentangling the Evidence of Milankovitch Forcing From Tree-Ring and Sedimentary Records

open access: yesFrontiers in Earth Science, 2022
Tree-ring records constitute excellent high-resolution data and provide valuable information for climate science and paleoclimatology. Tree-ring reconstructions of past temperature variations agree to show evidence for annual-to-centennial anomalies in ...
