  • Resilience of soil to biological invasion: analysis of spread on networks 

    Otten, Wilfred; Grinev, Dmitri V.; Perez-Reche, Francisco J.; Neri, Franco; Costa, Luciano da F.; Biana, Marcel; Gilligan, Christopher A.; Taraskin, Sergei N. (International Union of Soil Sciences, 2010-08)
    A network model for soil pore volume is presented and applied to the analysis of biological invasion of microorganisms. The pore geometry of two soils with a relatively high or low bulk density were quantified with the ...
  • Reverse engineering of biochar 

    Morales, Veronica L.; Perez-Reche, Francisco J.; Hapca, Simona M.; Hanley, Kelly L.; Lehmann, Johannes; Zhang, Wei (Elsevier, 2015-02-18)
    This study underpins quantitative relationships that account for the combined effects that starting biomass and peak pyrolysis temperature have on physico-chemical properties of biochar. Meta-data was assembled from published ...
  • Stable, metastable and unstable states in the mean-field random-field Ising model at T = 0 

    Rosinberg, Martin L.; Tarjus, Gilles; Perez-Reche, Francisco J. (Institute of Physics, 2008-10)
    We compute the probability distribution of the number of metastable states at a given applied field in the mean-field random-field Ising model at T = 0. Remarkably, there is a non-zero probability in the thermodynamic limit ...
  • Surfactant-mediated control of colloid pattern assembly and attachment strength in evaporating droplets 

    Morales, Veronica L.; Parlange, Jean-Yves; Wu, Mingming; Perez-Reche, Francisco J.; Zhang, Wei; Sang, Wenjing; Steenhuis, Tammo S. (American Chemical Society, 2013)
    This study demonstrates that the pattern assembly and attachment strength of colloids in an evaporating sessile droplet resting on a smooth substrate can be controlled by adding nonionic solutes (surfactant) to the solution. ...
  • Synergy in spreading processes: from exploitative to explorative foraging strategies 

    Perez-Reche, Francisco J.; Ludlam, Jonathan J.; Taraskin, Sergei N.; Gilligan, Christopher A. (American Physical Society, 2011-05)
    An epidemiological model which incorporates synergistic effects that allow the infectivity and/or susceptibility of hosts to be dependent on the number of infected neighbours is proposed. Constructive synergy induces an ...
  • The T = 0 random-field Ising model on a Bethe lattice with large coordination number: hysteresis and metastable states 

    Rosinberg, Martin L.; Tarjus, Gilles; Perez-Reche, Francisco J. (Institute of Physics, 2009-03)
    In order to elucidate the relationship between rate-independent hysteresis and metastability in disordered systems driven by an external field, we study the Gaussian RFIM at T = 0 on regular random graphs (Bethe lattice) ...
