• Self-propelled particle model for cell-sorting phenomena 

      Belmonte, Julio Monti; Thomas, Gilberto Lima; Brunnet, Leonardo Gregory; Almeida, Rita Maria Cunha de; Chate, Hugues (2008) [Artigo de periódico]
      A self-propelled particle model is introduced to study cell sorting occurring in some living organisms. This allows us to evaluate the influence of intrinsic cell motility separately from differential adhesion with ...
    • Space of interactions with definite symmetry in neural networks with biased patterns as a spin-glass problem 

      Theumann, Alba Graciela Rivas de (1996) [Artigo de periódico]
      We study the space of interactions of a connected neural network with biased patterns, when the synaptic interactions satisfy a symmetry constraint. We show that the solution to the problem requires the calculation of a ...
    • V2O3(0001) surface termination : phase equilibrium 

      Window, Amanda J.; Silva Junior, Agenor Hentz da; Sheppard, D. C.; Parkinson, G.S.; Niehus, Horst; Ahlbehrendt, D.; Noakes, Tim C. Q.; Bailey, Paul; Woodruff, D. P. (2011) [Artigo de periódico]
      Complementary but independent medium-energy and low-energy ion scattering studies of the (0001) surfaces of V₂O₃ films grown on Pd(111), Au(111) and Cu₃Au(100) reveal a reconstructed full O₃-layer termination creating a ...
    • What happened to the gas-liquid transition in the system of dipolar hard spheres? 

      Levin, Yan (1999) [Artigo de periódico]
      We explore the equilibrium properties of a system composed of dipolar hard spheres. A new theory based on the ideas derived from the work of Debye and Hückel, Bjerrum, and Onsager is proposed to explain the absence of the ...
