    The scope of financial systemic risk research encompasses a wide range of interbank channels and effects, including asset correlation shocks, default contagion, illiquidity contagion, and asset fire sales. This paper ...
  • Faqeeh, Ali; Melnik, Sergey; Colomer-deSimón, Pol; Gleeson, James P. (American Physical Society, 2016)
    It is commonly assumed in percolation theories that at most one percolating cluster can exist in a network. We show that several coexisting percolating clusters (CPCs) can emerge in networks due to limited mixing, i.e., a ...
  • Cellai, Davide; Fima, Andrzej Z; Lawlor, Aonghus; Dawson, Kenneth A (AIP Publishing, 2011)
    Glass-forming liquids have been extensively studied in recent decades, but there is still no theory that fully describes these systems, and the diversity of treatments is in itself a barrier to understanding. Here we ...
  • Cellai, Davide; Cuevas, Hector; Lawlor, Aonghus; McCullagh, Gavin D; Dawson, Kenneth A (American Physical Society, 2004)
    We describe a simple nearest-neighbor Ising model that is capable of supporting a gas, liquid, and crystal, in characteristic relationship to each other. As the parameters of the model are varied, one obtains characteri ...
  • McCullagh, Gavin D; Cellai, Davide; Lawlor, Aonghus; Dawson, Kenneth A (2005)
    We extend a previously studied lattice model of particles with infinite repulsions to the case of finite-energy interactions. The phase diagram is studied using grand canonical Monte Carlo simulation. Simulations of dynamical ...

    In multiplex networks, cycles cannot be characterized only by their length, as edges may occur in different layers in different combinations. We define a classification of cycles by the number of edges in each layer and ...
  • Baxter, Gareth J; Dorogovtsev, Sergey N; Mendes, José F.F; Cellai, Davide (Americann Physical Society, 2014)
    Bootstrap percolation is a simple but nontrivial model. It has applications in many areas of science and has been explored on random networks for several decades. In single-layer (simplex) networks, it has been recently ...
  • 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 ...
  • Baxter, Gareth J; Cellai, Davide; Dorogovtsev, Sergey N; Goltsev, A.V; Mendes, José F (Springer, 2016)
    Many real complex systems cannot be represented by a single network, but due to multiple sub-systems and types of interactions, must be represented as a multiplex network. This is a set of nodes which exist in several ...
  • 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 ...
  • Fennell, Peter G; Melnik, Sergey; Gleeson, James P. (American Physical Society, 2016)
    Continuous-time Markov process models of contagions are widely studied, not least because of their utility in predicting the evolution of real-world contagions and in formulating control measures. It is often the case, ...
  • Scully, Paul; Reid, Orlaith; Macken, Alan P; Healy, Mark; Saunders, Jean; Leddin, Des; Dunne, Colum; O'Gorman, Clodagh S (Dove Medical Press, 2016)
    Background: Television watching is obesogenic due to its sedentary nature and programming content, which influences children. Few studies have examined exercise placement within children-specific programming. This study ...
  • ÓhAiseadha, Coilín; Mannix, Mai; Saunders, Jean; Philip, Roy K (Kerman University of Medical Sciences, 2016)
    Background: Increasing demand for limited healthcare resources raises questions about appropriate use of inpatient beds. In the first paediatric bed utilisation study at a regional university centre in Ireland, we conducted ...
  • MacKenzie, Gilbert; Greig, Mary; Hay, Iris; Pemberton, John (BMJ Publishing Group, 2016)
    Background The 5-year follow-up results for the 1202 middle-aged men prospective study of CHD incidence were published in 1980. This paper extends the follow-up, relating the development of CHD to ten risk factors. Methods The ...
  • Haynes, M; O'Brien, Stephen BG; 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 ...
  • MacKenzie, Gilbert; Peng, Defen (2014)
    In the parametric regression models with categorical covariates, it is well known that many key quantities of interest are invariant to the choice of reference subclass. However, surprisingly, not all quantities are ...
  • Sheikhi, Ali; Ramsey, David; MacKenzie, Gilbert (2011)
    A selective sweep occurs when a positive mutation spreads through a population. It causes a reduction in variation among the nucleotides in the neighbourhood of the mutation. Whether or not a selective sweep has occurred can ...
  • MacKenzie, Gilbert (2015)
    Non-PH parametric survival modelling is developed within the frame- work of the multiple logistic function. The family considered comprises three basic models: (a) a PH model, (b) an accelerated life model and (c) a model ...

    Objectives: This study aims to (1) use the objective activPAL activity monitor to assess physical activity behaviors, including sitting/lying, standing, and both light (LIPA) and moderate-to-vigorous physical activity ...
  • MacKenzie, Gilbert; Conde, Susana (IWSM, 2016)
    We develop a Smooth Lasso for sparse, high dimensional, contingency tables and compare its performance with the usual Lasso and with the now classical backwards elimination algorithm. In simulation, the usual Lasso had ...
