  • Maher, Paul J.; MacCarron, Pádraig; Quayle, Michael (Wiley, 2020)
    Partisan patterns of compliance with public health measures are a feature of early COVID-19responses. In many cases, these differences in behaviour relate to pre-existing group identities. However, in times of rapid ...
  • Fennell, Susan C. (University of Limerick, 2021)
    Individuals’ opinions, beliefs and behaviours are formed through social interaction. In this thesis we are interested in the influence of social interaction on (i) how opinions spread and (ii) the emergence of ...
  • Gleeson, James P. (American Physical Society, 2008)
    The mean size of unordered binary avalanches on infinite directed random networks may be determined using the damage propagation function introduced by [B. Samuelsson and J. E. S. Socolar, Phys. Rev. E 74, 036113 (2006)]. ...
  • O'Brien, Joseph D.; Gleeson, James P. (American Physical Society, 2021)
    Simon’s classical random-copying model, introduced in 1955, has garnered much attention for its ability, in spite of an apparent simplicity, to produce characteristics similar to those observed across the spectrum of complex ...
  • Cellai, Davide; Dorogovtsev, Sergey N.; Bianconi, Ginestra (Ameriican Physical Society, 2016)
    Multiplex networks describe a large variety of complex systems, including infrastructures, transportation networks, and biological systems. Most of these networks feature a significant link overlap. It is therefore of ...
  • Zammett, R.J; Fowler, Andrew C. (Society for Industrial and Applied Mathematics, 2010)
    Spiral-shaped canyons on the polar ice caps of Mars are striking morphological features whose explanation is still mysterious. We pose a model for the kinetics at the ice-atmosphere interface based on the positive feedback ...
  • Moroney, Kevin M.; Kotamarthy, Lalith; Muthancheri, Indu; Ramachandran, Rohit; Vynnycky, Michael (Elsevier, 2021)
    Accurate mechanistic in vitro dissolution models can deliver insight into drug release behaviour and guide formulation development. Drug release profiles from drug-excipient granules can be impacted by variation of porosity ...
  • Melnik, Sergey; Ward, Jonathan A; Gleeson, James P.; Porter, Mason A (American Institute of Physics, 2013)
    The spread of ideas across a social network can be studied using complex contagion models, in which agents are activated by contact with multiple activated neighbors. The investigation of complex contagions can provide ...
  • Cellai, Davide; Bianconi, Ginestra (American Physical Society, 2016)
    In multiplex networks with a large number of layers, the nodes can have different activities, indicating the total number of layers in which the nodes are present. Here we model multiplex networks with heterogeneous activity ...
  • Keating, Leah A.; Gleeson, James P.; O'Sullivan, David J.P. (American Physical Society, 2022)
    Complex contagion adoption dynamics are characterized by a node being more likely to adopt after multiple network neighbors have adopted. We show how to construct multitype branching processes to approximate complex contagion ...
  • Gessey-Jones, Thomas; Connaughton, Colm; Dunbard, Robin; Kenna, Ralph; MacCarron, Pádraig; O'Conchobhaire, Cathal; Yose, Joseph (National Academy of Sciences, 2020)
    Network science and data analytics are used to quantify static and dynamic structures in George R. R. Martin’s epic novels, A Song of Ice and Fire, works noted for their scale and complexity. By tracking the network of ...

    Background This study reports the findings of the first large-scale Phase III investigator-driven clinical trial to slow the rate of cognitive decline in Alzheimer disease with a dihydropyridine (DHP) calcium channel ...
  • Carletti, Timoteo; Asllani, Malbor; Fanelli, Duccio; Latora, Vito (American Physical Society, 2020)
    Random walks are the simplest way to explore or search a graph and have revealed a very useful tool to investigate and characterize the structural properties of complex networks from the real world. For instance, they have ...
  • Timoney, Catherine M. (University of Limerick, 2017)
    This work is concerned with finding accurate numerical approximations to nonlinear reaction-diffusion problems that exhibit layer phenomena. It considers three variations of problems of this type. These are; a ...
  • Fannon, James S.; Fowler, Andrew C.; Moyles, Iain R. (The Royal Society Publishing, 2017)
    We summarize the present form of the instability theory for drumlin formation, which describes the coupled subglacial flow of ice, water and sediment. This model has evolved over the last 20 years, and is now at the point ...
  • Khaleque, Tania S; Fowler, Andrew C.; Howell, P D; Vynnycky, Michael (American Institute of Physics, 2015)
    Motivated by convection of planetary mantles, we consider a mathematical model for Rayleigh-Benard convection in a basally heated layer of a fluid whose viscosity depends strongly on temperature and pressure, defined in ...
  • Kohlstädt, Sebastian; Vynnycky, Michael; Goeke, Stephan; Gebauer-Teichmann, Andreas (MDPI, 2021)
    This paper investigates the critical plunger velocity in high-pressure die casting during the slow phase of the piston motion and how it can be determined with computational fluid dynamics (CFD) in open source software. ...
  • Vynnycky, Michael; Mitchell, Sarah L. (Cambridge University Press, 2022)
    In this paper, we consider the steady-state base flow for natural convection in a vertical porous slab with permeable boundaries. Although recent work proposed a one-dimensional solution for this flow, we make a strong ...
  • Vynnycky, Michael; Saleem, S.; Devine, Kevin M.; Florio, B. J.; Mitchell, Sarah L.; O'Brien, Stephen B.G. (The Royal Society, 2017)
    Asymptotic methods are employed to revisit an earlier model for oscillation-mark formation in the continuous casting of steel. A systematic non-dimensionalization of the governing equations, which was not carried out ...
  • Vynnycky, Michael (Elsevier, 2022)
    In this paper, we reassess the local solute redistribution equation (LSRE) of macrosegregation which, since it first appeared in 1960s, has served as a cornerstone for understanding the composition variations that occur ...
