(BLACKWELL, 2006-09)To test whether there are differences between living lineages of domestic guinea pigs Cavia porcellus, we studied 118 specimens from six breeds collected along six Andean countries as well as 15 from the wild cavy species ...
-
(Elife Sciences, 2021)The study of South American camelids and their domestication is a highly debated topic in zooarchaeology. Identifying the domestic species (alpaca and llama) in archaeological sites based solely on morphological data is ...

(Cambridge University Press, 2018)We consider the parabolic one-dimensional Allen-Cahn equation ut = uxx + u(1-u2), (x, t) R x (-0]. The steady state w(x) = tanh(x/2) connects, as a 'transition layer', the stable phases-1 and +1. We construct a solution u ...

(Elsevier Science BV, 2018)We consider the parabolic Allen Cahn equation in R-n, n >= 2, u(t) = Delta u + (1 - u(2))u in R-n x (-infinity, 0]. We construct an ancient radially symmetric solution u(x, t) with any given number k of transition ...

(Interciencia Association, 2017)It is thought that adaptive changes protect high-altitude populations against altitude-induced diseases, but information from well controlled studies is lacking. In a prospective, controlled study, we assessed the prevalence ...
-
(American Geophysical Union, 2020)The southern Central Andes recorded retroarc shortening, basin evolution, and magmatic arc migration during Neogene changes in subduction. At 31-33 degrees S, above the modern flat-slab segment, spatial and temporal linkages ...
-
(Macmillan Publishers Limited, 2013-04-28)Segmentation can influence the extent of earthquake rupture and event magnitude(1): large megathrust earthquakes result from total rupture of relatively continuous segments of the subduction interface(2-5). Segmentation ...
-
(ELSEVIER SCIENCE BV, 2005-06)Sr-Nd isotopic analyses on some mantle xenolith samples from the Northern, Southern and Austral Andean volcanic zones exhibit radiogenic Sr enrichment without dramatic changing of the Nd isotopic composition. This anomalous ...
-
(OPTICAL SOC AMER, 2012-02-15)We investigate experimentally the light evolution inside a two-dimensional finite periodic array of weakly coupled optical waveguides with a disordered boundary. For a completely localized initial condition away from the ...
