Issue Auto-Assignment in Software Projects with Machine Learning Techniques
Pedro Oliveira, Rossana M. C. Andrade, Tales P. Nogueira +2
Usually, managers or technical leaders in software projects assign issues manually. This task may become more complex as more detailed is the issue description. This complexity can…
Cracking urban mobility
H. A. Carmona, A. W. T. de Noronha, A. A. Moreira +2
Assessing the resilience of a road network is instrumental to improve existing infrastructures and design new ones. Here we apply the optimal path crack model (OPC) to investigate…
Effect of zitterbewegung on the propagation of wave packets in ABC-stacked multilayer graphene: an analytical and computational approach
I. R. Lavor, D. R. da Costa, Andrey Chaves +4
The time evolution of a low-energy two-dimensional Gaussian wave packet in ABC-stacked -layer graphene (ABC-NLG) is investigated. Expectation values of the position of c…
Hardness of some variants of the graph coloring game
Thiago Marcilon, Nicolas Martins, Rudini Sampaio
Very recently, a long-standing open question proposed by Bodlaender in 1991 was answered: the graph coloring game is PSPACE-complete. In 2019, Andres and Lock proposed five variant…
Ground state and collective excitations of a dipolar Bose-Einstein condensate in a bubble trap
Pedro de Castro Diniz, Eduardo Amâncio Barbosa Oliveira, Aristeu Rosendo Pontes Lima +1
We consider the ground state and the low-lying excitations of dipolar Bose-Einstein condensates in a bubble trap, i.e., a shell-shaped spherically symmetric confining potential. By…
A wavelet analysis of photometric variability in Kepler white dwarf stars
S. R. de Lira, J. P. Bravo, I. C. Leao +4
This work brings a wavelet analysis for 14 Kepler white dwarf stars, in order to confirm their photometric variability behavior and to search for periodicities in these targets. Fr…
Debris disks among Kepler solar rotational analog stars
R. Silva Sobrinho, A. D. Da Costa, B. L. Canto Martins +8
Observations of circumstellar disks provide a powerful tool for our understanding of planetary systems dynamics. Analogs to the Solar System asteroid belts, debris disks result fro…
Topological Classification and Finite Determinacy of knotted maps
Juan José Nuño Ballesteros, Rodrigo Mendes
We show that the knot type of the link of a real analytic map germ with isolated singularity is a complete invariant for -$\mathsc…
Four-manifolds with positive curvature
R. Diógenes, E. Ribeiro, E. Rufino
In this note we prove that a four-dimensional compact oriented half-confor\-mally flat Riemannian manifold is topologically or pr…
Ground state of an ultracold Fermi gas of tilted dipoles in elongated traps
Vladimir Veljic, Aristeu R. P. Lima, Lauriane Chomaz +5
Many-body dipolar effects in Fermi gases are quite subtle as they energetically compete with the large kinetic energy at and below the Fermi surface (FS). Recently it was experimen…
Metrically un-knotted corank 1 singularities of surfaces in
Lev Birbrair, Rodrigo Mendes, Juan Jose Nuño-Ballesteros
The paper is devoted to relations between topological and metric properties of germs of real surfaces, obtained by analytic maps from to . We show that for a big class o…
Depletion forces on circular and elliptical obstacles induced by active matter
L. R. Leite, D. Lucena, F. Q. Potiguar +1
Depletion forces exerted by self-propelled particles on circular and elliptical passive objects are studied using numerical simulations. We show that a bath of active particles can…
Bound vortex states and exotic lattices in multi-component Bose-Einstein condensates: The role of vortex-vortex interaction
Davi S. Dantas, Aristeu R. P. Lima, A. Chaves +3
We numerically study the vortex-vortex interaction in multi-component homogeneous Bose-Einstein condensates within the realm of the Gross-Pitaevskii theory. We provide strong evide…
Low-Lying Excitation Modes of Trapped Dipolar Fermi Gases: From Collisionless to Hydrodynamic Regime
F. Waechtler, A. R. P. Lima, A. Pelster
By means of the Boltzmann-Vlasov kinetic equation we investigate dynamical properties of a trapped, one-component Fermi gas at zero temperature, featuring the anisotropic and long-…
Gauge field localization on the Bloch Brane
W. T. Cruz, Aristeu R. P. Lima, C. A. S. Almeida
We present new results on the localization of gauge fields in thick brane models. The four-dimensional observable universe is considered to be a topological defect which is generat…
Uniqueness of quasi-Einstein metrics on 3-dimensional homogeneous manifolds
A. Barros, E. Ribeiro, J. Silva Filho
The purpose of this article is to study the existence and uniqueness of quasi-Einstein structures on -dimensional homogeneous Riemannian manifolds. To this end, we use the eight…
Overspill avalanching in a dense reservoir network
G. L. Mamede, N. A. M. Araújo, C. M. Schneider +2
Sustainability of communities, agriculture, and industry is strongly dependent on an effective storage and supply of water resources. In some regions the economic growth has led to…
