  • Rocha, Marcio S. (Biopolymers, 2009-08-20)
    We review the neighbor exclusion model and some of its applications to analyze the binding data of DNA-ligand complexes. We revisit the closed form of the model developed by McGhee and von Hippel in 1974, showing that this ...
  • Reis, L. A.; Rocha, M. S. (Biopolymers, 2017-01-18)
    In this work, we use force spectroscopy to investigate the interaction between the DAPI fluorescent dye and the k-DNA molecule under high (174 mM) and low (34 mM) ionic strengths. Firstly, we have measured the changes on ...
  • Ferreira, Silvio C.; Ferreira, Ronan S.; Castellano, Claudio; Pastor-Satorras, Romualdo (Physical Review E, 2011-12-05)
    We present high-accuracy quasistationary (QS) simulations of the contact process in quenched networks, built using the configuration model with both structural and natural cutoffs. The critical behavior is analyzed in the ...
  • Silva, E. F.; Bazoni, R. F.; Ramos, E. B.; Rocha, M. S. (Biopolymers, 2016-10-05)
    We have investigated the interaction of the DNA molecule with the anticancer drug doxorubicin (doxo) by using three different experimental techniques: single molecule stretching, single molecule imaging, and dynamic light ...
  • Ferreira, Silvio C.; Castellano, Claudio; Pastor-Satorras, Romualdo (Physical Review E, 2012-10-15)
    Recent work has shown that different theoretical approaches to the dynamics of the susceptible-infected-susceptible (SIS) model for epidemics lead to qualitatively different estimates for the position of the epidemic ...
  • Mól, L. A. S.; Costa, B. V. (Journal of Physics: Condensed Matter, 2010-01-12)
    In this work we have used extensive Monte Carlo simulations and finite size scaling theory to study the phase transition in the dipolar planar rotator model (dPRM), also known as dipolar XY model. The true long-range ...
  • Mata, Angélica S.; Ferreira, Silvio C.; Pastor-Satorras, Romualdo (Physical Review E, 2013-10-30)
    We investigate the effects of local population structure in reaction-diffusion processes representing a contact process (CP) on metapopulations represented as complex networks. Considering a model in which the nodes of a ...
  • Stariolo, Daniel A.; Arenzon, Jeferson J. (Physical Review E., 1999-05-01)
    We study by means of Monte Carlo simulations the off-equilibrium properties of a model glass, the frustrated Ising lattice gas in three dimensions. We have computed typical two times quantities, such as density-density ...
  • Silva, Priscila C. A. da; Rosembach, Tiago V.; Santos, Anésia A.; Rocha, Márcio S.; Martins, Marcelo L. (Plos One, 2014-09-09)
    In multicellular organisms, cell motility is central in all morphogenetic processes, tissue maintenance, wound healing and immune surveillance. Hence, failures in its regulation potentiates numerous diseases. Here, cell ...
  • Silva, Saimon Filipe Covre da; Mardegan, Thayná; Araújo, Sidnei Ramis de; Ramirez, Carlos Alberto Ospina; Kiravittaya, Suwit; Couto, Odilon D. D. Jr; Iikawa, Fernando; Deneke, Christoph (Nanoscale Research Letters, 2017-01-21)
    We use a combined process of Ga-assisted deoxidation and local droplet etching to fabricate unstrained mesoscopic GaAs/AlGaAs structures exhibiting a high shape anisotropy with a length up to 1.2 μm and a width of 150 nm. ...
  • Fumiã, Herman F.; Martins, Marcelo L. (Plos One, 2013-07-26)
    A Boolean dynamical system integrating the main signaling pathways involved in cancer is constructed based on the currently known protein-protein interaction network. This system exhibits stationary protein activation ...
  • Podestá, Tatiane Souza Vilela; Rosembach, Tiago Venzel; Santos, Anésia Aparecida dos; Martins, Marcelo Lobato (Plos One, 2017-07-10)
    In multicellular organisms, cell motility is central in all morphogenetic processes, tissue maintenance, wound healing and immune surveillance. Hence, the control of cell motion is a major demand in the creation of artificial ...
  • Ferreira, Sukarno O.; Zamiri, Marziyeh; Anwar, Farhana; Klein, Brianna A.; Rasoulof, Amin; Dawson, Noel M.; Schuler-Sandy, Ted; Deneke, Christoph F.; Cavallo, Francesca; Krishna, Sanjay (Proceedings of the National Academy of Sciences of the United States of America, 2016-11-15)
    Antimonide compounds are fabricated in membrane form to enable materials combinations that cannot be obtained by direct growth and to support strain fields that are not possible in the bulk. InAs/(InAs,Ga)Sb type II ...
  • Almeida, Renan A. L.; Ferreira, Sukarno O.; Ferraz, Isnard; Oliveira, Tiago J. (Scientific Reports, 2017-06-19)
    The Kardar-Parisi-Zhang (KPZ) class is a paradigmatic example of universality in nonequilibrium phenomena, but clear experimental evidences of asymptotic 2D-KPZ statistics are still very rare, and far less understanding ...
  • Viol, A.; Palhano-Fontes, Fernanda; Onias, Heloisa; Araujo, Draulio B. de; Viswanathan, G. M. (Scientific Reports, 2017-08-07)
    The entropic brain hypothesis holds that the key facts concerning psychedelics are partially explained in terms of increased entropy of the brain’s functional connectivity. Ayahuasca is a psychedelic beverage of Amazonian ...
