Analyzing Dominance Move (MIP-DoM) Indicator for Multi- and Many-objective Optimization
Claudio Lucio do Val Lopes, Flávio Vinícius Cruzeiro Martins, Elizabeth Fialho Wanner +1
Dominance move (DoM) is a binary quality indicator that can be used in multi-objective and many-objective optimization to compare two solution sets obtained from different algorith…
The neutron star inner crust: an empirical essay
Luiz L. Lopes
In this work we study how the small contribution of the inner crust to the total equation of state (EoS) of a neutron star affects its mass-radius relation, focusing on the canonic…
A Population-based Hybrid Approach to Hyperparameter Optimization for Neural Networks
Marcello Serqueira, Pedro González, Eduardo Bezerra
In recent years, large amounts of data have been generated, and computer power has kept growing. This scenario has led to a resurgence in the interest in artificial neural networks…
Experimental realisation of multipartite entanglement via quantum Fisher information in a uniform antiferromagnetic quantum spin chain
George Mathew, Saulo L. L. Silva, Anil Jain +9
Quantum entanglement is a quantum mechanical phenomenon where the quantum state of a many-body system with many degrees of freedom cannot be described independently of the state of…
Characterizing dynamical states of Galactic open clusters with Gaia DR2
M. S. Angelo, W. J. B. Corradi, J. F. C. Santos +2
In this work, we investigate the dynamical properties of 38 Galactic open clusters: 34 of them are located at low Galactic latitudes (|b| < 10) and are projected against…
Modified MIT Bag Models -- part II: QCD phase diagram and hot quark stars
Luiz L. Lopes, Carline Biesdorf, K. D. Marquez +1
In the present work we use the modified versions of the MIT bag model, on which both a vector field and a self-interacting term are introduced, to obtain hot quark matter and to in…
The VISCACHA survey -- II. Structure of star clusters in the Magellanic Clouds periphery
J. F. C. Santos, F. F. S. Maia, B. Dias +11
We provide a homogeneous set of structural parameters of 83 star clusters located at the periphery of the Small Magellanic Cloud (SMC) and the Large Magellanic Cloud (LMC). The clu…
Discovery and astrophysical properties of Galactic open clusters in dense stellar fields using Gaia DR2
Filipe A. Ferreira, J. F. C. Santos, W. J. B. Corradi +2
We report the discovery of 25 new open clusters resulting from a search in dense low galactic latitude fields. We also provide, for the first time, structural and astrophysical par…
On the monotonicity of the critical time in the Constrained-degree percolation model
Charles S. do Amaral, A. P. F. Atman, Bernardo N. B. de Lima
The Constrained-degree percolation model was introduced in [B.N.B. de Lima, R. Sanchis, D.C. dos Santos, V. Sidoravicius, and R. Teodoro, Stoch. Process. Appl. (2020)], where it wa…
Modified MIT bag Models -- part I: Thermodynamic consistency, stability windows and symmetry group
Luiz L. Lopes, Carline Biesdorf, Débora P. Menezes
In this work we study different variations of the MIT bag model. We start with the so called non-ideal bag model and discuss it in detail. Then we implement a vector interaction in…
No radiative corrections to the Carroll-Field-Jackiw term beyond one-loop order
L. C. T. Brito, J. C. C. Felipe, A. Yu. Petrov +1
We demonstrate explicitly the absence of the quantum corrections to the Carroll-Field-Jackiw (CFJ) term beyond one-loop within the Lorentz-breaking CPT-odd extension of QED. The pr…
Asymptotics for Nonlinear Integral Equations with a Generalized Heat Kernel using Renormalization Group Technique II: Marginal Perturbations and Logarithmic Corrections to the Time Decay of Solutions
Gastão A. Braga, Jussara M. Moreira, Camila F. Souza
In this paper, we proceed with the analysis started in \cite{bib:braga-mor-souza} and, using the Renormalization Group method, we obtain logarithmic corrections to the decay of sol…
EGFC: Evolving Gaussian Fuzzy Classifier from Never-Ending Semi-Supervised Data Streams -- With Application to Power Quality Disturbance Detection and Classification
Daniel Leite, Leticia Decker, Marcio Santana +1
Power-quality disturbances lead to several drawbacks such as limitation of the production capacity, increased line and equipment currents, and consequent ohmic losses; higher opera…
Broken SU(6) symmetry and massive hybrid stars
Luiz L. Lopes, Debora P. Menezes
In this work we revisit the quantum hadrodynamics (QHD) formalism to investigate hyperonic and hybrid stars with hyperon-meson couplings fixed via broken SU(6) group, in favor of a…
Characterizing low contrast Galactic open clusters with GAIA DR2
M. S. Angelo, J. F. C. Santos, W. J. B. Corradi
In this study, we characterized 16 objects previously classified as faint or low contrast Galactic open clusters (OCs). We employed parameters associated to the OCs dynamical evolu…
