Lower Bounds for the Pfaffian Number of Graphs
Enrique Junchaya, Alberto Alexandre Assis Miranda, Cláudio L. Lucchesi
The number of perfect matchings of a -pfaffian graph can be counted by computing a linear combination of the pfaffians of matrices. The pfaffian number of a graph is the…
A pilot study on canonical gravity with mass dimension one fermions
R. de C. Lima, T. M. Guimarães, S. H. Pereira
The mass dimension one (MDO) fermionic field is built on a complete set of dual-helicity eigenspinors of the charge conjugation operator, which obeys the statistic of Fermi-Dirac.…
Overcoming Bias in Community Detection Evaluation
Jeancarlo Campos Leão, Alberto H. F. Laender, Pedro O. S. Vaz de Melo
Community detection is a key task to further understand the function and the structure of complex networks. Therefore, a strategy used to assess this task must be able to avoid bia…
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…
COVID-ABS: An Agent-Based Model of COVID-19 Epidemic to Simulate Health and Economic Effects of Social Distancing Interventions
Petrônio C. L. Silva, Paulo V. C. Batista, Hélder S. Lima +3
The COVID-19 pandemic due to the SARS-CoV-2 coronavirus has directly impacted the public health and economy worldwide. To overcome this problem, countries have adopted different po…
Exotic fermionic fields and minimal length
J. M. Hoff da Silva, D. Beghetto, R. T. Cavalcanti +1
We investigate the effective Dirac equation, corrected by merging two scenarios that are expected to emerge towards the quantum gravity scale. Namely, the existence of a minimal le…
