Refactoring for Novices in Java: An Eye Tracking Study on the Extract vs. Inline Methods
José Aldo Silva da Costa, Rohit Gheyi, José Júnior Silva da Costa +5
Developers often extract methods to improve readability, understanding, and reuse, while inlining keeps logic in one block. Prior work based on static metrics has not shown clear d…
The BINGO project X. Cosmological parameter constraints from HI Intensity Mapping lognormal simulations
Pablo Motta, Filipe B. Abdalla, Camila P. Novaes +12
Context. Building on the transformative success of optical redshift surveys, the emerging technique of neutral hydrogen (HI) intensity mapping (IM) offers a novel probe of large-sc…
Universality in quasinormal modes of a magnetized black hole
Marcos R. Ribeiro, Eveling C. Ribeiro, Kai Lin +1
In this work, we investigate the linear stability of a magnetized Einstein-Maxwell solution describing a static, axially symmetric black hole (BH) immersed in a uniform magnetic fi…
Axial Gravitational Normal Modes of Uniform Density Star in Anti-de Sitter Spacetime
Kai Lin, Alan B. Pavan, Amilcar Rabelo de Queiroz +1
The article studies the dynamical behavior of axial gravitational perturbations of homogeneous stars in Anti-de Sitter spacetime. Because the radial coordinate transforms into…
Machine learning analysis of Photometric data from the Dark Energy Survey
Elcio Abdalla, Filipe B. Abdalla, Alessandro Marins +3
In order to retrieve cosmological parameters from photometric surveys, we need to estimate the distribution of the photometric redshift in the sky with excellent accuracy. We use a…
Hierarchical Control for the Oldroyd Equation in Memoriam to Professor Luiz Adauto Medeiros
Isaías Pereira de Jesus, Marcondes Rodrigues Clark, Alexandro Marinho Oliveira +1
This manuscript deals with a hierarchical control problem for Oldroyd equation under the Stackelberg-Nash strategy. The Oldroyd equation model is defined by non-regular coefficient…
