Perturbative Analysis of CPT-Odd Lorentz-Violating Scalar QCD
J. C. C. Felipe, L. C. T. Brito, A. C. Lehum +2
We perform a complete one-loop renormalization analysis of CPT-odd Lorentz-violating scalar quantum chromodynamics with adjoint scalar matter. Working to first order in the preferr…
Metric-Induced Principal Symbols in Nonlinear Electrodynamics
Érico Goulart, Eduardo Bittencourt
We present a geometrical formulation of nonlinear electrodynamics by expressing its principal symbol as an optical metric-induced object. Under the assumption of no birefringence,…
Propagation features of Lorentz-violating electrodynamics
E. Goulart, J. E. Ottoni, J. C. C. Felipe
This paper explores some propagation features of electrodynamics in a Lorentz-violating scenario, focusing on a specific CPT-even term within the photon sector of the Standard Mode…
CTDGSI: A comprehensive exploitation of instance selection methods for automatic text classification. VII Concurso de Teses, Dissertações e Trabalhos de Graduação em SI -- XXI Simpósio Brasileiro de Sistemas de Informação
Washington Cunha, Leonardo Rocha, Marcos André Gonçalves
Progress in Natural Language Processing (NLP) has been dictated by the rule of more: more data, more computing power and more complexity, best exemplified by the Large Language Mod…
Ambiguities in the generation of CFJ-terms in a QED with dimension-5 operators in one loop
H. G. Fargnoli, J. C. C. Felipe, G. Gazzola
In this paper, we investigate a Lorentz symmetry breaking extension of Quantum Electrodynamics (QED), incorporating 5-dimensional CPT-odd terms at the one-loop level. Employing an…
A Framework for Building Enviromics Matrices in Mixed Models
B. A. Trevisan, V. S. Junqueira, B. M. Florencio +3
This study introduces a framework for constructing enviromics matrices in mixed models to integrate genetic and environmental data to enhance phenotypic predictions in plant breedi…
Selective tracking of charge carrier dynamics in CuInS2 quantum dots
Andrés Burgos-Caminal, Brener R. C. Vale, André F. V. Fonseca +20
CuInS2 quantum dots have been studied in a broad range of applications, but despite this, the fine details of their charge carrier dynamics remain a subject of intense debate. Two…
Mimicking a rotating black hole with nonlinear electrodynamics
Érico Goulart, Eduardo Bittencourt
We exhibit the first analogue model of a rotating black hole constructed in the framework of nonlinear electrodynamics. The background electromagnetic field is assumed to be algebr…
Modified Euler-Heisenberg effective action and Proper-Time Method in Lorentz-Violating Scalar QED
L. C. T. Brito, J. C. C. Felipe, A. C. Lehum +2
Quantum photon effects in vacuum provide an interesting setting to test quantum electrodynamics, serving as a source for predictions about physics beyond the Standard Model. In thi…
Nonuniversal critical dynamics on planar random lattices with heterogeneous degree distributions
Sidiney G. Alves, Silvio C. Ferreira, Marcelo M. de Oliveira
The weighted planar stochastic (WPS) lattice introduces a topological disorder that emerges from a multifractal structure. Its dual network has a power-law degree distribution and…
Photon traps in nonlinear electrodynamics
Érico Goulart, Eduardo Bittencourt
We demonstrate the existence of photon traps within the framework of nonlinear electrodynamics. The trapping mechanism is based on the fact that, for null background fields, the op…
Optimizing Beer Glass Shapes to Minimize Heat Transfer During Consumption
Claudio de Castro Pellegrini
This paper addresses the problem of determining the optimum shape for a beer glass that minimizes the heat transfer while the liquid is consumed, thereby keeping it cold for as lon…

ATLAS Collaboration
A search for high-mass resonances decaying into a -lepton and a neutrino using proton-proton collisions at a center-of-mass energy of TeV is presented. The full Ru…
Remarks on the algebraic structure of (2, 2) double forms
E. Goulart, J. E. Ottoni
We study the algebraic features of covariant tensors of valence four containing two blocks of skew indices. After a rather general treatment, we specialize ourselves to four-dimens…
Can Offline Metrics Measure Explanation Goals? A Comparative Survey Analysis of Offline Explanation Metrics in Recommender Systems
André Levi Zanon, Marcelo Garcia Manzato, Leonardo Rocha
In Recommender System (RS), explanations help users understand why items are recommended and can enhance a system's transparency, persuasiveness, engagement, and trust, which are k…
Exact Foldy-Wouthuysen transformation for a Dirac equation describing the interaction of spin-1/2 relativistic particles with an external electromagnetic field
Bruno Gonçalves, Mário M. Dias Júnior, Larissa F. Eleotério
The Thomas-Bargmann-Michel-Telegdi (T-BMT) equation is derived using the Exact Foldy-Wouthuysen transformation. Extra new terms were found, and we discuss their possible physical a…
The Schwinger and Chiral Schwinger Models in a Non-perturbative Spectral Regularization
L. F. Eleotério, G. A. Oliveira, E. W. Dias +2
We investigate the employment of a non-perturbative regularization scheme -- the spectral regularization, which is based on the gauge technique, previously implemented in the conte…
