Left ventricular noncompactation and pre-excitation: an unusual finding in adults
(HCPA/FAMED/UFRGS, 2017)
Ground and excited state properties of alizarin and its isomers
(Elsevier, 2014-01)
Four different alizarin dyes are studied with optical, electrochemical and quantum-chemical techniques. Despite structural similarities they show marked differences regarding both ground and excited state properties. All ...
Towards a global classification of excitable reaction-diffusion systems
(Elsevier Science, 2000-02)
Patterns in reaction-diffusion systems near primary bifurcations can be studied locally and classified by means of amplitude equations. This is not possible for excitable reaction-diffusion systems. In this paper we propose ...
An excitable electronic circuit as a sensory neuron model
(World Scientific, 2012-10)
An electronic circuit device, inspired on the FitzHughNagumo model of neuronal excitability, was constructed and shown to operate with characteristics compatible with those of biological sensory neurons. The nonlinear ...
Structural characterization, optical properties and photocatalytic activity of MOF-5 and its hydrolysis products: implications on their excitation mechanism
(Royal Society of Chemistry, 2015-08-21)
The existing concerns on the limited stability of Zn4O-based MOFs upon exposure to humidity or aqueous environments, as well as on the excitation mechanisms, are discussed on the basis of Raman, FTIR, DR-UV and XRD ...
Excited states of 4He droplets
(American Physical Society, 2001-05)
We study low-lying excited states of 4He clusters up to a cluster size of 40 atoms in a variational framework. The ansatz wave function combines two- and three-body correlations, coming from a translationally invariant ...
Electronic excited states of protonated aromatic molecules: Protonated Fluorene
(Elsevier Science, 2012-01)
The photo-fragmentation spectrum of protonated fluorene has been recorded in the visible spectral region, evidencing an absorption that appears largely red shifted in comparison to that of the neutral molecule fluorene. ...
Sturmian expansions for two-electron atomic systems: Singly and doubly excited states
(American Physical Society, 2010-10)
We present a configuration interaction (CI) method based on the Sturmian expansion for bound states of a two-electron atomic system. These Sturmian functions are solutions of one-electron quantum mechanical problems, where ...
Pump excited state absorption in holmium-doped fluoride glass
(American Institute of Physics (AIP), 2008-01-15)
The primary excited state absorption processes relating to the (5)I(6) -> (5)I(7) 3 mu m laser transition in singly Ho(3+)-doped fluoride glass have been investigated in detail using time-resolved fluorescence spectroscopy. ...
Excitations of interface pinned domain walls in constrained geometries
(AIP Publishing LLC, 2017-12-05)
We report a theoretical investigation of the equilibrium pattern and the spectra of head-to-head and Neel domain walls of flat Fe and Py stripes, exchange coupled with a vicinal antiferromagnetic substrate. We show that ...
