Three new Galactic star clusters discovered in the field of the open cluster NGC 5999 with Gaia DR2
Filipe A. Ferreira, J. F. C. Santos, W. J. B. Corradi +2
We report the serendipitous discovery of three new open clusters, named UFMG 1, UFMG 2 and UFMG 3 in the field of the intermediate-age cluster NGC 5999, by using Gaia DR2 data. A c…
Regularized Fuzzy Neural Networks to Aid Effort Forecasting in the Construction and Software Development
Paulo Vitor de Campos Souza, Augusto Junio Guimaraes, Vanessa Souza Araujo +2
Predicting the time to build software is a very complex task for software engineering managers. There are complex factors that can directly interfere with the productivity of the d…
The Exact Foldy-Wouthuysen Transformation for a Dirac Theory Revisited
Bruno Gonçalves, Mário M. Dias Júnior, Baltazar J. Ribeiro
The Exact Foldy-Wouthuysen transformation (EFWT) method is generalized here. In principle, it is not possible to construct the EFWT to any Hamiltonian. The transformation condition…
Probing molecular environments with a Fictitious isotopic dipole
José R. Mohallem, Paulo F. G. Velloso, Antonio F. C. Arapiraca
A HD-like isotopic dipole moment is proposed as a sensible probe for molecular environments, in particular for electrostatic fields and polarizable (reactive) sites of molecules. F…
Consistency of an alternative CPT-odd and Lorentz-violating extension of QED
J. C. C. Felipe, H. G. Fargnoli, A. P. Baeta Scarpelli +1
We investigate an alternative CPT-odd Lorentz-breaking QED which includes the Carroll-Field-Jackiw (CFJ) term of the Standard Model Extension (SME), writing the gauge sector in the…
Higher-order one-loop contributions in Lorentz-breaking QED
A. P. Baeta Scarpelli, L. C. T. Brito, J. C. C. Felipe +2
We calculate higher-order quantum contributions in different Lorentz-violating parameters to the gauge sector of the extended QED. As a result of this one-loop calculation, some te…
Assessing diversity in multiplex networks
L. C. Carpi, T. A. Schieber, P. M. Pardalos +4
Diversity, understood as the variety of different elements or configurations that an extensive system has, is a crucial property that allows maintaining the system's functionality…
The when and where of water in the history of the universe
Karla de Souza Torres, Othon Cabo Winter
It is undeniable that life as we know it depends on liquid water. It is difficult to imagine any biochemical machinery that does not require water. On Earth, life adapts to the mos…
Persistence and Stochastic Periodicity in the Intensity Dynamics of a Fiber Laser During the Transition to Optical Turbulence
Laura Carpi, Cristina Masoller
Many natural systems display transitions among different dynamical regimes, which are difficult to identify when the data is noisy and high dimensional. A technologically relevant…
Chaos-based Potentials in the One-dimensional Tight-binding Model Probed by the Inverse Participation Ratio
Weslley Florentino de Oliveira, Giancarlo Queiroz Pellegrino
Chaos-based potentials are defined and implemented in the one-dimensional tight-binding model as a way of simulating disorder-controlled crystalline lattices. In this setting, diso…
Quantum phase transition in an effective three-mode model of interacting bosons
H. M. Frazão, J. G. Peixoto de Faria, G. Q. Pellegrino +1
In this work we study an effective three-mode model describing interacting bosons. These bosons can be considered as exciton-polaritons in a semiconductor microcavity at the magic…
