(2011)We report the first data on nesting ecology of the Slender-billed Parakeet (Enicognathus leptorhynchus) from two wild nests in native temperate rainforests of southern Chile. Nests were located in natural cavities 19 m up ...
-
(Elsevier, 2020)This research presents the first pliosaur remains from the Upper Jurassic of the Atacama Desert, in northern Chile. Two specimens recovered from Oxfordian levels, are represented by a fragmentary mandibular ramus and by ...
-
(Elsevier, 2017)Density Functional Theory (DFT) has been used to study structural and electronic properties of new compounds based on V-implanted Si and their potential as infrared photodetectors. Effects derived from the implantation of ...
-
(Inst Paleobiologii Pan, 2021)We describe partial remains of a non-pterodactyloid pterosaur from Upper Jurassic levels of the Atacama Desert in northern Chile. The material includes a left humerus, a possible dorsal vertebra, and the shaft of a wing ...

(Taylor & Francis, 2015)In this study, we report the first record of mites of the genus Leptus (Latreille, 1796) (Trombidiformes: Erythraeidae) found on the triatomine Mepraia spinolai (Maza, Gajardo and Jorg, 1940) (Hemiptera: Rudiviidae), one ...
-
(Elsevier, 2020)We describe fragmentary ichthyosaur skull remains of a single individual recovered from Lower Jurassic marine strata in northern Chile. The preserved teeth display distinctive features such as a very long, robust and ...
-
(Amer Physical Soc, 2016)The role of oxygen doping in CdTe is addressed by first-principles calculations. Formation energies, charge transition levels, and quasiparticle defect states are calculated within the DFT + GW formalism. The formation of ...
-
(Royal Soc Chemistry, England, 2021)A theoretical study of the Mn trimer adsorbed on the noble metal surfaces Au(111) and Cu(111) is reported. The calculations were performed using first-principles methods within the density functional theory and the generalized ...
