First analysis of mitochondrial lineages from the eastern Pampa–Patagonia transition during the final late Holocene
(Wiley-liss, div John Wiley & Sons Inc., 2020-04)
Objective: Studies on population genetics have become highly relevant for understanding the evolutionary history of human settlement in southern South America. The eastern Pampa–Patagonia transition is an area that stands ...
New insights on sources contributing dust to the loess record of the western edge of the Pampean Plain during the transition from the late MIS 2 to the early Holocene
(Sage Publications Ltd, 2019-09)
High-resolution studies of palaeorecords located closer to the dust source areas of South America are relevant for increasing the knowledge on past climatic conditions in the Southern Hemisphere. In this sense, the Pampean ...
Palaeomagnetism of the Upper Carboniferous-Lower Permian transition from Paganzo basin, Argentina
(Wiley Blackwell Publishing, Inc, 2004-06)
A palaeomagnetic study of Upper Palaeozoic rocks was performed on Paganzo basin, central-western Argentina and its western extension, Río Blanco subbasin. The volcanic-volcaniclastic Rio del Peñón and marine sedimentary ...
Clogging transition of many-particle systems flowing through bottlenecks
(Nature Publishing Group, 2014-11)
When a large set of discrete bodies passes through a bottleneck, the flow may become intermittent due to the development of clogs that obstruct the constriction. Clogging is observed, for instance, in colloidal suspensions, ...
A General Approach to Model Movement in (Highly) Fragmented Patch Networks
(Amer Statistical Assoc & Int Biometric Soc, 2017-09)
Landscape heterogeneity can often be represented as a series of discrete habitat or resource patches surrounded by a matrix of non-habitat. Understanding how animals move in such networks of patches is important for many ...
Vertical drafts and mixing in stratified turbulence: Sharp transition with Froude number
(Europhysics Letters, 2018-08)
We investigate the large-scale intermittency of vertical velocity and temperature, and the mixing properties of stably stratified turbulent flows using both Lagrangian and Eulerian fields from direct numerical simulations ...
Psychosine remodels model lipid membranes at neutral pH
(Elsevier Science, 2018-12)
β-Galactosylsphingosine or psychosine (PSY) is a single chain sphingolipid with a cationic group, which is degraded in the lysosome lumen by β-galactosylceramidase during sphingolipid biosynthesis. A deficiency of this ...
Clogging transition of many particle systems flowing through bottlenecks
(Scientific Reports, 2018)
One-dimensional diffusion: Validity of various expressions for jump rates
(American Physical Society, 2009-12)
The coverage dependence of the one-dimensional collective diffusion coefficient is analyzed by using the gradient expansion of the local density. The transition probabilities are written as an expansion of the probabilities ...
Socioeconomic status and self-reported chronic diseases among Argentina’s adult population: Results based on multivariate probability models
(Page Press Publications, 2017-07)
Background. Hypertension, diabetes and hypercholesterolemia are the most frequent and diagnosed chronic diseases in Argentina. They contribute largely to the burden of chronic disease and they are strongly influenced by a ...
