Heterotic α' corrections in Double Field Theory
(Springer, 2014-12-10)
We extend the generalized flux formulation of Double Field Theory to include all the first order bosonic contributions to the α´ expansion of the heterotic string low energy effective theory. The generalized tangent space ...
The gauge structure of Exceptional Field Theories and the tensor hierarchy
(Springer, 2014-04-07)
We address the construction of manifest U-duality invariant generalized diffeomorphisms. The closure of the algebra requires an extension of the tangent space to include a tensor hierarchy indicating the existence of an ...
Heavy flavor relaxation in a hadronic medium
(2013)
Charm and bottom transport coefficients in a medium constituted of light mesons, such as is formed in the hadronic phase of heavy-ion collisions, are obtained within an effective field theory approach implementing heavy-quark ...
Combined experimental and theoretical investigations of the photoluminescent behavior of Ba(Ti,Zr)O-3 thin films
(Elsevier B.V., 2007-11-01)
The correlation between experimental data and theoretical calculations have been investigated to explain the photoluminescence at room temperature of Ba(Ti0.75Zr0.25)O-3 (BTZ) thin films prepared by the polymeric precursor ...
A new spin-2 self-dual model in D=2+1
(Int School Advanced Studies, 2009-09-01)
There are three self-dual models of massive particles of helicity + 2 (or -2) in D = 2 + 1. Each model is of first, second, and third-order in derivatives. Here we derive a new self-dual model of fourth-order, L(SD)((4)), ...
Octagons I: combinatorics and non-planar resummations
(2019-08-01)
We explain how the ’t Hooft expansion of correlators of half-BPS operators can be resummed in a large-charge limit in N = 4 super Yang-Mills theory. The full correlator in the limit is given by a non-trivial function of ...

(Elsevier B.V., 2007-11-01)
The correlation between experimental data and theoretical calculations have been investigated to explain the photoluminescence at room temperature of Ba(Ti0.75Zr0.25)O-3 (BTZ) thin films prepared by the polymeric precursor ...
Maximally non-Markovian quantum dynamics without environment-to-system backflow of information
(American Physical Society, 2018-05)
The degree of non-Markovianity allows one to characterize quantum evolutions that depart from a Markovian regime in a similar way as the Schmidt number measures the degree of entanglement of pure states. Maximally non-Markovian ...
Probabilidades imprecisas: intervalar, fuzzy e fuzzy intuicionista
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia ElétricaAutomação e Sistemas; Engenharia de Computação; Telecomunicações, 2012-08-20)
The idea of considering imprecision in probabilities is old, beginning with the Booles
George work, who in 1854 wanted to reconcile the classical logic, which allows the modeling
of complete ignorance, with probabilities. ...
Doutores em ciências contábeis: análise sob a óptica da teoria do capital humano
(Associação Nacional dos Programas de Pós-graduação em Administração, 2010)
Os pressupostos da teoria do capital humano estabelecem que as pessoas se educam e que o principal efeito da educação é a mudança que ela provoca nas habilidades e conhecimentos de quem estuda. A consequência prevista é ...
