Rescue of endemic states in interconnected networks with adaptive coupling
(Nature Publishing Group, 2016-07)
We study the Susceptible-Infected-Susceptible model of epidemic spreading on two layers of networks interconnected by adaptive links, which are rewired at random to avoid contacts between infected and susceptible nodes at ...
Photo-activatable surfaces for cell migration assays
(Wiley Vch Verlag, 2013-12)
A simple material platform for advanced cell migration studies is presented. It relies on surfaces modified with photo-activatable adhesion peptides and two light exposure steps to independently trigger attachment and ...
Winding-number dependence of Bose-Einstein condensates in a ring-shaped lattice
(American Physical Society, 2011-01)
We study the winding-number dependence of the stationary states of a Bose-Einstein condensate in a ring-shaped lattice. The system is obtained by confining atoms in a toroidal trap with equally spaced radial barriers. We ...
Signature of Nonadiabatic Coupling in Excited-State Vibrational Modes
(American Chemical Society, 2014-05)
Using analytical excited-state gradients, vibrational normal modes have been calculated at the minimum of the electronic excited-state potential energy surfaces for a set of extended conjugated molecules with different ...
Effective two-mode model in Bose-Einstein condensates versus Gross-Pitaevskii simulations
(Springer, 2017-11)
We study the dynamics of three-dimensional Bose-Einstein condensates confined by double-well potentials using a two-mode (TM) model with an effective on-site interaction energy parameter. The effective on-site interaction ...
Surface plasmon enhancement of spontaneous emission in graphene waveguides
(IOP Publishing, 2016-10)
This work analyzes the spontaneous emission of a single emitter placed near the graphene waveguide formed by two parallel graphene monolayers, with an insulator spacer layer. In this case, the eigenmodes supported by the ...
The Australasian muricid gastropod Lepsiella as Pleistocene visitor to southernmost South America
(Polish Academy Of Sciences. Institute Of Paleobiology, 2013-12)
Six shells belonging to a muricid gastropod species were recovered from a Pleistocene marine raised beach located on Navarino Island, in southern South America. None of the living species in the Beagle Channel or in the ...
The spatial and temporal construction of confidence in the visual scene
(Public Library of Science, 2009-03)
Human subjects can report many items of a cluttered field a few hundred milliseconds after stimulus presentation. This memory decays rapidly and after a second only 3 or 4 items can be stored in working memory. Here we ...
PROPÉRCIO RECIDIVO
(Instituto de Letras - Universidade Federal do Rio Grande do Sul, 2017)
Enhanced transmission via cavity modes in gratings formed by subwavelength metallic cylinders
(Optical Society of America, 2017-12)
In the last few decades, special attention has been paid to the optical response of structures composed of periodic subwavelength slits in thin metallic sheets. Extraordinary transmission and evanescent-to-propagating ...
