Helix-coil transitions re-visited
(Elsevier Science, 2002-12)
The thermally-induced helix-coil transition in polyamino acids is a good model for determining the helix-forming propensities of amino acids but not for the two-state folding/unfolding transition in globular proteins. The ...
Vegetational history of the Late glacial - Holocene transition in the grasslands of eastern Argentina
(Elsevier Science, 2000-04)
Palynological records from eight sites located in the eastern plains of Argentina, from the humid Pampa in the east to the xerophytic woodland–dry Pampa ecotone in the west, allow a regional reconstruction of the vegetation ...
Xerophytic Forest Record of the Pleistocene/Holocene Transition and Use of Wood Resources by Early Human Groups in the Eastern Tandilia Range, Argentina
(Taylor & Francis, 2020-07)
This contribution analyzes the charcoal records found in archaeological sites dating to the Pleistocene/Holocene transition (9032 ± 30 - 10,672 ± 56 radiocarbon years ago) located in the eastern Tandilia Range, Buenos Aires ...
Glass transition of LiCl aqueous solutions confined in mesoporous silica
(American Institute of Physics, 2019-08)
The thermal transitions of confined LiCl aqueous solutions were studied by differential scanning calorimetry for solutions with salt concentrations with eutectic (R = 7) and subeutectic (R > 7) compositions (R = moles of ...
Additional constraints in adsorption-desorption kinetics
(American Physical Society, 2009-02)
In this work, the adsorption-desorption kinetic in the framework of the lattice gas model is analyzed. The transition probabilities are written as an expansion of the occupation configurations. Due to that, the detail ...
Pathways of megaherbivore rewilding transitions: Typologies from an Andean gradient
(University of California Press, 2020-05)
In most of the planet, large herbivore communities have been replaced by livestock, but this process is reversing in many places. Here, we outline and review the pathways of "megaherbivore rewilding transitions"in three ...
Emergence of power law distributions for odd and even lifetimes
(American Physical Society, 2020-12-24)
Avalanche lifetime distributions have been related to first-return random walk processes. In this sense, the theory for random walks can be employed to understand, for instance, the origin of power law distributions in ...
Central limit theorem for a class of globally correlated random variables
(American Physical Society, 2016-06)
The standard central limit theorem with a Gaussian attractor for the sum of independent random variables may lose its validity in the presence of strong correlations between the added random contributions. Here, we study ...
Calcaneus fracture in a Middle Holocene individual from the eastern Pampa-Patagonian transition (Argentina)
(Elsevier Science, 2021-08)
Calcaneus fractures are scarcely reported in archaeological assemblages worldwide. The main goal of this paper is to present a study case related to a calcaneus fracture and a set of bone lesions recorded in an adult ...
Contemporaneous-threshold smooth transition GARCH models
