Permanent junctional reciprocating tachycardia in a patient with an atypically located accessory pathway in the left lateral mitral annulus

open access: yesRevista Portuguesa de Cardiologia, 2016
Permanent junctional reciprocating tachycardia (PJRT) is an uncommon form of atrioventricular reentrant tachycardia due to an accessory pathway characterized by slow and decremental retrograde conduction.

Scaling in light scattering by sharp conical metal tips [PDF]

open access: yesarXiv, 2016
Using the electrostatic approximation, we analyze electromagnetic fields scattered by sharp conical metal tips, which are illuminated with light polarized along the tip axis. We establish scaling relations for the scattered field amplitude and phase, whose validity is verified with numerical simulations.

Ablation of multifocal premature ventricular contractions using automated pace-mapping software

open access: yesRevista Portuguesa de Cardiologia, 2022
Introduction and Objectives: Ablation of multifocal premature ventricular complexes (PVCs) is challenging. Activation mapping can be performed for the predominant morphology, but may be useless for other less prevalent ones.

Analog computing using reflective plasmonic metasurfaces [PDF]

open access: yesarXiv, 2016
Motivated by the recent renewed interest in compact analog computing using light and metasurfaces (Silva, A. et al., Science 2014, 343, 160-163), we suggest a practical approach to its realization that involves reflective metasurfaces consisting of arrayed gold nanobricks atop a subwavelength-thin dielectric spacer and optically-thick gold film, a ...

Crioablação versus ablação por radiofrequência da taquicardia reentrante nodal auriculoventricular : metanálise [PDF]

open access: yes, 2015
Introdução: A Taquicardia Reentrante Nodal Auriculoventricular (TRNAV) é a arritmia supraventricular regular mais comum no ser humano, constituindo igualmente a arritmia supraventricular mais encaminhada para a ablação.

Gold Photoluminescence Wavelength and Polarization Engineering [PDF]

open access: yesarXiv, 2016
We demonstrate engineering of the spectral content and polarization of photoluminescence (PL) from arrayed gold nanoparticles atop a subwavelength-thin dielectric spacer and optically-thick gold film, a configuration that supports gap-surface plasmon resonances (GSPRs).

Universality of vector sequences and universality of Tverberg partitions [PDF]

open access: yesarXiv, 2018
A result of Rosenthal says that for every $q>1$ and $n \in \mathbb{N}$ there is $N \in \mathbb{N}$ such that every sequence of $N$ distinct positive numbers contains, after a suitable translation and possible multiplication by $-1$, a subsequence $a_1,\ldots,a_n$ that is either $q$-increasing (that is, $a_{i+1}>qa_i$ for all $i$) or $1/q$-decreasing ...
