Experimental Kuramoto Platform
Leandro Freitas, Victor H. S. Bittencourt, Débora D. Superbi +3
Phase reduction provides a principled relationship between high-dimensional oscillator dynamics and low-dimensional phase models such as the Kuramoto model. However, connecting ana…
Modeling Programming Skills with Source Code Embeddings for Context-aware Exercise Recommendation
Carlos Eduardo P. Silva, João Pedro M. Sena, Julio C. S. Reis +2
In this paper, we propose a context-aware recommender system that models students' programming skills using embeddings of the source code they submit throughout a course. These emb…
"A 6 or a 9?": Ensemble Learning Through the Multiplicity of Performant Models and Explanations

Multi-objective evolutionary algorithms (MOEAs) are essential for solving complex optimization problems, such as the diet problem, where balancing conflicting objectives, like cost…
Almost reducibility, distortion and local perfection for diffeomorphisms of one-manifolds
Hélène Eynard-Bontemps, Emmanuel Militon
In this article, we characterize the distortion elements of the group of smooth diffeomorphisms of the circle and of the group of compactly supported smooth diffeomorphisms of the…
Maximum Dispersion, Maximum Concentration: Enhancing the Quality of MOP Solutions
Gladston Moreira, Ivan Meneghini, Elizabeth Wanner
Multi-objective optimization problems (MOPs) often require a trade-off between conflicting objectives, maximizing diversity and convergence in the objective space. This study prese…
The BPHZL renormalization of a planar quantum electrodynamics up to 2-loops and beyond
D. O. R. Azevedo, O. M. Del Cima, L. S. Lima +1
The renormalization of a parity-even massless quantum electrodynamics in three space-time dimensions (QED) is studied by adopting the Bogoliubov-Parasiuk-Hepp…
Cosmological Forecasts from the Baryon Acoustic Oscillations in 21cm Intensity Mapping
Benjamin Ostergaard, André Alencar da Costa, Yu Sang
In this work we use a template method to extract the scale associated with the Baryon Acoustic Oscillation (BAO) signal in 21cm neutral hydrogen intensity maps. We then forecast th…
Revisiting the strain-induced softening behaviour in hydrogels
L. K. R. Duarte, L. G. Rizzi
Usually, the strain-induced softening behaviour observed in the differential modulus of hydrogels has been attributed to the breakage of internal structures of the network…
NoCodeGPT: A No-Code Interface for Building Web Apps with Language Models
Mauricio Monteiro, Bruno Castelo Branco, Samuel Silvestre +2
In this paper, we first report an exploratory study where three participants were instructed to use ChatGPT to implement a simple Web-based application. A key finding of this study…
Phyllosilicates as earth-abundant layered materials for electronics and optoelectronics: Prospects and challenges in their ultrathin limit
Ingrid D. Barcelos, Raphaela de Oliveira, Gabriel R. Schleder +10
Phyllosilicate minerals are an emerging class of naturally occurring layered insulators with large bandgap energy that have gained attention from the scientific community. This cla…
On the origin of the negative energy-related contribution to the elastic modulus of rubber-like gels
L. K. R. Duarte, L. G. Rizzi
We consider a coarse-grained polymer model in order to investigate the origin of a recently discovered negative energy-related contribution to the elastic modulus of rubber-…
Functional observability and subspace reconstruction in nonlinear systems
Arthur N. Montanari, Leandro Freitas, Daniele Proverbio +1
Time-series analysis is fundamental for modeling and predicting dynamical behaviors from time-ordered data, with applications in many disciplines such as physics, biology, finance,…
Theoretical analysis of magnetic properties and the magnetocaloric effect using the Blume-Capel model
S. Oliveira, R. H. M. Morais, J. P. Santos +1
This work investigates the magnetic properties and the magnetocaloric effect in the spin-1 Blume-Capel model. The study was carried out using the mean-field theory from the Bogoliu…
Residual gauge-invariance in a massive Lorentz-violating extension of QED
B. Alves Marques, A. P. Baêta Scarpelli, J. C. C. Felipe +1
We reassess an alternative CPT-odd electrodynamics obtained from a Palatini-like procedure. Starting from a more general situation, we analyze the physical consistency of the model…
Supporting Real Demands in Software Engineering with a Four Steps Project-Based Learning Approach
Leonardo Humberto Silva, Renata Xavier Castro, Marice Costa Guimaraes
Project-based learning (PBL) is a student-centered and learn-by-doing approach that organizes learning around projects. While entrepreneurship and PBL in SE education are thrilling…
