  • Del Cima, O. M. (Physics Letters B, 2013-03-13)
    The massive even-parity non-Abelian gauge model in three space–time dimensions proposed by Jackiw and Pi is studied at the tree-level. The propagators are computed and the spectrum consistency is analyzed, besides, the ...
  • Carrasco, I. S. S.; Oliveira, T. J. (Physical Review E, 2018-07)
    Recent experimental works on one-dimensional (1D) circular Kardar-Parisi-Zhang (KPZ) systems whose radii decrease in time have reported controversial conclusions about the statistics of their interfaces. Motivated by this, ...
  • Mata, Angélica S.; Boguñá, Marian; Castellano, Claudio; Pastor-Satorras, Romualdo (Physical Review E, 2015-05-12)
    In a recent work, a new numerical method (the lifespan method) has been introduced to study the critical properties of epidemic processes on complex networks [M. Boguñá, C. Castellano, and R. Pastor-Satorras, Phys. Rev. ...
  • Ferreira, Silvio C.; Luis, Edwin E. Mozo; Assis, Thiago A. de; Andrade, Roberto F. S. (Physical Review, 2019-02)
    We report local roughness exponents, αloc, for three interface growth models in one dimension which are believed to belong to the nonlinear molecular-beam-epitaxy (nMBE) universality class represented by the Villain-Lais-Das ...
  • Oporto, Zui; Constantinidis, Clisthenis P.; Piguet, Olivier (Classical and Quantum Gravity, 2015)
    We present a complete quantization of Lorentzian D = 1 + 2 gravity with cosmological constant, coupled to a set of topological matter fields. The approach of loop quantum gravity is used thanks to a partial gauge fixing ...
  • Piguet, O. (Astronomische Nachrichten, 2014-08-05)
    In this talk, I give a short general introduction to Loop Quantum Gravity (LQG), beginning with some motivations for quantizing General Relativity, listing various attempts and then focusing on the case of LQG.
  • Felix, J. F.; Figueiredo, L. C.; Mendes, J. B. S.; Morais, P. C.; Araujo, C. I. L. de (Journal of Magnetism and Magnetic Materials, 2015-12-01)
    In this study we investigate magnetic properties, surface morphology and crystal structure in iron nanoclusters electrodeposited on lightly doped (100) n-type silicon substrates. Our goal is to investigate the spin injection ...
  • Velásquez, Rober (Superlattices and Microstructures, 2006-02-17)
    In this work we describe a magnetotunneling spectroscopy technique for probing the localization degree of two-dimensional states and mapping the subbands in the active region of a resonant-tunneling semiconductor ...
  • Carvalho, Sylvestre Aureliano; Silva, Stella Olivia da; Charret, Iraziet da Cunha (Theory in Biosciences, 2018-04)
    Dengue is, in terms of death and economic cost, one of the most important infectious diseases in the world. So, its mathematical modeling can be a valuable tool to help us to understand the dynamics of the disease and to ...
  • Oliveira-Neto, N. M.; Souza, J. de; Ribeiro-Silva, C. I. (The European Physical Journal D - Atomic, Molecular, Optical and Plasma Physics, 2006-06-30)
    We propose a method, based on a generalized Heisenberg algebra (GHA), to reproduce the anharmonic spectrum of diatomic molecules. The theoretical spectrum generated by GHA allows us to fit the experimental data and to ...
  • Rodrigues, Nathann T; Oliveira, Tiago J (Journal of Physics A: Mathematical and Theoretical, 2014)
    We study a generalized interacting self-avoiding walk (ISAW) model with nearest- and next nearest-neighbor (NN and NNN) interactions on square and cubic lattices. In both dimensions, the phase diagrams show coil and globule ...
  • Mata, Angélica S.; Ferreira, Silvio C. (Physical Review E, 2015-01-22)
    The epidemic threshold of the susceptible-infected-susceptible (SIS) dynamics on random networks having a power law degree distribution with exponent γ > 3 has been investigated using different mean-field approaches, which ...
  • Paiva, Leticia R.; Binny, Christopher; Ferreira Jr., Silvio C.; Martins, Marcelo L. (Cancer Research, 2009-01-27)
    One of the most promising strategies to treat cancer is attacking it with viruses. Oncolytic viruses can kill tumor cells specifically or induce anticancer immune response. A multiscale model for virotherapy of cancer is ...
  • Souza, D. R. de; Martins, M. L.; Carmo, F. M. S. (Biological Invasions, 2009-09-18)
    In the present paper, we propose and study by numerical simulations a multiscale model for plant invasion based on allelopathic suppression in a homogeneous environment. The negative effects on seed production and germination, ...
  • Paiva, Leticia R .; Silva, Hallan S.; Ferreira, Silvio C.; Martins, Marcelo L. (Physical Biology, 2013-03-15)
    Oncolytic virotherapy—the use of viruses that specifically kill tumor cells—is an innovative and highly promising route for treating cancer. However, its therapeutic outcomes are mainly impaired by the host immune response ...
  • Martins, M. L.; Ferreira Jr., S. C.; Vilela, M. J. (Current Opinion in Colloid & Interface Science, 2010-04)
    Life, amazingly rich in diversity of shapes and functions, explores the limits of extreme complexity in nature. In this review we shall discuss in general terms the use of multiscale mathematical and computer models to ...
  • Martins, M. L.; Ferreira Jr., S. C.; Vilela, M. J. (Physics of Life Reviews, 2007-06)
    In the past 30 years we have witnessed an extraordinary progress on the research in the molecular biology of cancer, but its medical treatment, widely based on empirically established protocols, still has many limitations. ...
  • Felix, J. F.; Cunha, D. L. da; Pereira, G. F. C.; Aguiar, J. Albino; Azevedo, W. M. de (Materials Research Bulletin, 2014-01)
    This article presents a chemical bottom-up synthesis of highly crystalline and nanostructured hydrocerussite (Pb3(CO3)2(OH)2) with hexagonal morphology prepared by laser ablation in liquid. The results demonstrate that is ...
  • Oliveira, Tiago J.; Stilck, Jürgen F. (Physical Review E, 2016-01-27)
    We study the interacting self-avoiding trail (ISAT) model on a Bethe lattice of general coordination q and on a Husimi lattice built with squares and coordination q=4. The exact grand-canonical solutions of the model are ...
  • Franco, D. H. T.; Cima, O. M. Del; Piguet, O.; Schweda, M. (Physics Letters B, 2009-09-14)
    In this Letter we call into question the perturbatively parity breakdown at 1-loop for the massless QED3 frequently claimed in the literature. As long as perturbative quantum field theory is concerned, whether a parity ...
