  • Mitchell, Sarah L.; McInerney, N.P.; O'Brien, Stephen B.G. (Elsevier, 2021)
    This study examines a one-dimensional Stefan problem describing the sorption of a finite amount of swelling solvent in a glassy polymer. The polymer is initially in a dry non-swollen state, where the polymer network is ...
  • da Cunha, Bruno Requião; MacCarron, Pádraig; Passold, Jean Fernando; dos Santos, Luiz Walmocyr; Oliveira, Kleber A.; Gleeson, James P. (2020)
    The networked nature of criminals using the dark web is poorly understood and infrequently studied, mostly due to a lack of data. Rarer still are studies on the topological effectiveness of police interventions. Between ...
  • Moroney, Kevin M.; Lee, William T.; O'Brien, Stephen B.G.; Suijver, Freek; Marra, Johan (Society for Industrial and Applied Mathematics, 2016)
    Extraction of coffee solubles from roast and ground coffee is a highly complex process, depending on a large number of brewing parameters. We consider a recent, experimentally validated, model of coffee extraction, describing ...
  • Haynes, Matthew; O'Brien, Stephen B.G.; Benilov, Eugene (AIP Publishing, 2016)
    This paper uses asymptotic techniques to find the shape of a two dimensional liquid bridge suspended between two vertical walls. We model the equilibrium bridge shape using the Laplace-Young equation. We use the Bond number ...
  • Fowler, Andrew C. (Springer, 2021)
    This paper addresses the problem of extinction in continuous models of population dynamics associated with small numbers of individuals. We begin with an extended discussion of extinction in the particular case of a ...
  • Gleeson, James P. (American Physical Society, 2013)
    A wide class of binary-state dynamics on networks-including, for example, the voter model, the Bass diffusion model, and threshold models-can be described in terms of transition rates (spin-flip probabilities) that depend ...
  • Lee, William T.; Fowler, Andrew C.; Power, O.; Healy, Sandra; Browne, J. (American Institute of Physics, 2010)
    Polycrystalline silicon fuses are one time programmable memory elements which allow the calibration of integrated circuits at wafer and package level. We present a zero-dimensional lumped parameter model of the programming ...
  • Gleeson, James P. (American Physical Society, 2009)
    Analytical results are derived for the bond percolation threshold and the size of the giant connected component in a class of random networks with nonzero clustering. The network's degree distribution and clustering spectrum ...
  • Hackett, Adam W.; Cellai, Davide; Gomez, S.; Arenas, Alex; Gleeson, James P. (American Physical Society, 2016)
    We present an analytical approach for bond percolation on multiplex networks and use it to determine the expected size of the giant connected component and the value of the critical bond occupation probability in these ...
  • Gleeson, James P.; Onaga, Tomokatsu; Fennell, Peter; Cotter, James; Burke, Raymond; O'Sullivan, David J.P. (Oxford University Press, 2021)
    A detailed analysis of Twitter-based information cascades is performed, and it is demonstrated that branching process hypotheses are approximately satisfied. Using a branching process framework, models of agent-to-agent ...
  • Gleeson, James P.; Murphy, Thomas Brendan; O'Brien, Joseph D.; Friel, Nial; Bargary, Norma; O'Sullivan, David J.P. (The Royal Society Publishing, 2021)
    We describe the population-based susceptible-exposed-infected-removed (SEIR) model developed by the Irish Epidemiological Modelling Advisory Group (IEMAG), which advises the Irish government on COVID-19 responses. The model ...
  • Hackett, Adam W.; Melnik, Sergey; Gleeson, James P. (American Physical Society, 2011)
    We present an analytical approach to determining the expected cascade size in a broad range of dynamical models on the class of random networks with arbitrary degree distribution and nonzero clustering introduced previously ...
  • Hackett, Adam W.; Gleeson, James P. (American Physical Society, 2013)
    We present an analytical approach to determining the expected cascade size in a broad range of dynamical models on the class of highly clustered random graphs introduced by Gleeson [J. P. Gleeson, Phys. Rev. E 80, 036107 ...
  • Dubber, Donata; Knappe, Jan; Gill, Laurence W. (MDPI, 2021)
    This research has used fluorescence spectroscopy and parallel factor analysis (PARAFAC) in order to characterize dissolved organic matter in septic tank effluent, as it passes through the biomat/biozone, infiltrating ...
  • Faqeeh, Ali; Osat, Saeed; Radicchi, Filippo (American Physical Society, 2018)
    We show that the community structure of a network can be used as a coarse version of its embedding in a hidden space with hyperbolic geometry. The finding emerges from a systematic analysis of several real-world and ...
  • Moroney, Kevin M.; Lee, William T.; O'Brien, Stephen B.G.; Suijver, Freek; Marra, Johan (SpringerOpen, 2016)
    The extraction of coffee solubles from roasted and ground coffee is a complex operation, the understanding of which is key to the brewing of high quality coffee. This complexity stems from the fact that brewing of coffee ...
  • Gleeson, James P.; Ward, Jonathan A; O'Sullivan, Kevin P.; Lee, William T. (American Physical Society, 2014)
    Heavy-tailed distributions of meme popularity occur naturally in a model of meme diffusion on social networks. Competition between multiple memes for the limited resource of user attention is identified as the mechanism ...
  • O'Brien, Joseph D.; Gleeson, James P. (Oxford University Press, 2021)
    A detailed analysis of matches played in the sport of Snooker during the period 1968–2020 is used to calculate a directed and weighted dominance network based upon the corresponding results. We consider a ranking procedure ...
  • Devine, Kevin M.; O'Kiely, D.; Vynnycky, Michael; Silveri, F.; Tommasi, A.; Abinaya, S.; Geaney, H.; Ryan, K.M (Elsevier, 2022)
    In this paper, we present and analyse a coupled electrochemomechanical model for the cycling of a nanowire composed of amorphous Si coated on Cu15Si4, using large-deformation theory. This study is motivated by a recent ...
  • Zeglinski, Jacek; Kuhs, Manuel; Khamar, Dikshitkumar; Hegarty, Avril C.; Devi, Renuka K.; Rasmuson, Åke C. (Wiley and Sons Ltd, 2018)
    The influence of the solvent in nucleation of tolbutamide, a medium-sized, flexible and polymorphic organic molecule, has been explored by measuring nucleation induction times, estimating solvent-solute interaction ...
