(Elsevier GmbH., 2013)The nurse-protégé hypothesis states that adult plants of one species provide micro-environmental conditions that favor the establishment of seedlings of a second species with no effect for the first species. Several studies ...
-
(2011)The rate of pollen exchange within and among flowers may depend on pollinator attraction traits such as floral display size and flowering plant density. Variations in these traits may influence pollinator movements, pollen ...
-
(Institute of Physics Publishing, 2005)We explore the nature of the faint blue objects in the Hubble Deep Field-South. We have derived proper motions for the point sources in the Hubble Deep Field-South using a 3 yr baseline. Combining our proper-motion ...
-
(2007)We study the transport of atoms across a localized Bose-Einstein condensate in a one-dimensional optical lattice. For atoms scattering off the condensate, we predict total reflection as well as full transmission for certain ...
-
(2005)We study resonant light scattering in arrays of channel optical waveguides in which tunable quadratic non-linearity is introduced as nonlinear defects by periodic poling of single (or several) waveguides in the array. We ...
-
(2011)We study the scattering of magnetoinductive plane waves by internal (external) capacitive (inductive) defects coupled to a one-dimensional split-ring resonator array. We examine a number of simple defect configurations ...
-
(Optical Society of America (OSA), 2009)We study a waveguide array with an embedded nonlinear saturable impurity. We solve the impurity problem in closed form and find the nonlinear localized modes. Next, we consider the scattering of a small-amplitude plane ...
-
(MDPI AG, POSTFACH, CH-4005 BASEL, SWITZERLAND, 2016)A small Chilean variety of pears growing in the town of Toconao, an oasis located at the northeastern edge of the Salar de Atacama, northern Chile, was studied by means of modern PDA and high resolution mass spectral data ...
-
(Pergamon Journals Ltd., 1987-01-25)8attus archidamas larvae reared on Aristolochia chilensis sequester aristolochic acids selectively and independently of lipophilícíty. A considerable proportion of the ingasted acids can be recovered from the excreta, but ...
-
(2013)Phototransduction, the mechanism underlying the electrical response to light in photoreceptor cells, has been thoroughly investigated in Drosophila melanogaster, an essential model in signal transduction research. These ...
-
(Frontiers Media, 2016)White Chilean strawberries (Fragaria chiloensis) are non-climacteric fruits, with an exotic color and aroma. In order to discover genes involved in the development of these fruits, we identified a fragment of a gene encoding ...
-
(Sociedad Chilena de Quimica, 2000)Reaction of CpFe(dppe)I with dithiopyridine in methanol and in presence of NH4PF6 affords the new mixed valence complex {[CpFe(dppe)]2 - n - S - Py}(PF6)2 (1 ). Observation of an intervalence electron transfer affords the ...
-
(2006-08-07)The stability, electronic and magnetic properties of Fe atoms adsorbed on the self-assembled Bilines nanostructure on the H/Si(001) surface are addressed by spin-density functional calculations. Our results show that Fe ...

(AMER INST PHYSICS, 2006-08-28)The stability and electronic and magnetic properties of Fe atoms adsorbed on the self-assembled Bi-line nanostructure on the H/Si(001) surface are addressed by spin-density functional calculations. Our results show that ...
-
(IOP Publishing, 2020)Wave-particle interactions are believed to be one of the most important kinetic processes regulating the heating and acceleration of solar wind plasma. One possible explanation for the observed preferential heating of alpha ...
-
(2009)We apply basic tools of control theory to a chemostat model that describes the growth of one species of microorganisms that consume a limiting substrate. Under the assumption that available measurements of the model have ...
-
(Springer, 2014)Specific fatty acids (FA) such as unsaturated (UFA) and saturated (SFA) fatty acids contained in foods are key factors in the nutritional ecology of birds. By means of a field and experimental approach, we evaluated the ...
-
(2001)Feeding by the aphid Sipha flava produces a reddish spot on mature leaves of Sorghum halepense. The present work is aimed at determining whether this plant response entails induced resistance against the aphid. Old and ...
-
(Cambridge University Press, 2008)In this research we studied the diet of Enteroctopus megalocyathus from three principal locations of the octopus fishery (Ancud, Quellón and Melinka) in southern Chile. The gastric contents of 523 individuals, collected ...
-
(1972)In terms of the usual RKKY indirect exchange interaction, the spiral antiferromagnetic phase of Europium cannot be attributed to a 'nesting' of opposite faces of the tetracube portion of the Fermi surfaces. © 1972.
