(Universidad de Chile., 1976)NGC 630 es un objeto muy peculiar; su formación fue causada por un evento muy violento, que generó una nebulosa no simétrica , Esta nebulosa tiene una estructura filamentaria y su estrella central no se puede ver porque ...
-
(American Physical Society, 2015)We demonstrate the first experimental realization of a dispersionless state, in a photonic Lieb lattice formed by an array of optical waveguides. This engineered lattice supports three energy bands, including a perfectly ...
-
(Elsevier, 2017)We experimentally study the transport properties of dipolar and fundamental modes on one dimensional (1D) coupled waveguide arrays. By carefully modulating a wide optical beam, we are able to effectively excite dipolar or ...
-
(IOP Publishing Ltd, 2018)We report on the experimental realization of a quasi-one-dimensional photonic graphene ribbon supporting four flat-bands (FBs). We study the dynamics of fundamental and dipolar modes, which are analogous to the s and p ...
-
(OPTICAL SOC AMER, 2010-08-15)We study experimentally light localization at phase-slip waveguides and at the intersection of phase-slips in a two-dimensional (2D) square photonic lattice. Such system allows to observe a variety of effects, including ...
-
(2013)Phosphofructokinase-2 is a dimeric enzyme that undergoes cold denaturation following a highly cooperative N2 2I mechanism with dimer dissociation and formation of an expanded monomeric intermediate. Here, we use intrinsic ...
-
(AMERICAN PHYSICAL SOC, 2006-08-25)We report on the observation of surface gap solitons found to exist at the interface between uniform and periodic dielectric media with defocusing nonlinearity. We demonstrate strong self-trapping at the edge of a LiNbO3 ...

Observation of the gradual transition from one-dimensional to two-dimensional Anderson localization (OPTICAL SOC AMER, 2012-02-15)We study the gradual transition from one-dimensional (1D) to two-dimensional (2D) Anderson localization upon transformation of the dimensionality of disordered waveguide arrays. An effective transition from a 1D to a 2D ...

(Neotropical Ornithological Society, 2017)The Chestnut-throated Huet-huet (Pteroptochus castaneus) is a poorly known species, endemic to Chile and Argentina. Here we describe observations made during eight days on a nest with two nestlings of the Chestnut-throated ...

(Sociedade Brasileira Ornitologia, 2017)Although the Variable Hawk (Geranoaetus polyosoma) is a common and broadly distributed raptor in the Neotropics, its breeding ecology is almost unknown. Using video cameras, we collected data on the parental and nestling ...

(2009)We report four opportunistic field observations of a species of Abrocoma in Polylepis besseri woodlands in Cochabamba Department, Bolivia. These observations sug-gest four significant aspects of Abrocoma sp. natural history: ...
-
(Universisdad de Chile, 1995)Los canales de K+ constituyen el grupo mas diverso dentro de la familia de los canales iónicos. Ellos se activan en respuesta a cambios en el potencial de membrana, a segundos mensajeros como AMPc o Ca2+ y vía proteína ...
-
(2001)A simple separation method to obtain gibberellin standards is described.This includes isolation of the lactonic gibberellins GAg, GA4, GAy and GAgfrom Gibberella fujikuroi cultures by Chromatographie procedures and their ...
