  • Gleeson, James P.; Melnik, Sergey; Ward, Jonathan A; Porter, Mason A; Murcha, Peter J (American Physical Society, 2012)
    Mean-field analysis is an important tool for understanding dynamics on complex networks. However, surprisingly little attention has been paid to the question of whether mean-field predictions are accurate, and this is ...
  • MacKenzie, Gilbert (IWSM, 2004)
    Conventionally, in longitudinal studies, the mean structure has been thought to be more important than the covariance structure between the repeated measures on the same individual. Often, it has been argued that, with ...
  • Butler, John S; Beiser, Ines M; Williams, Laura; McGovern, Eavan; Molloy, Fiona; Lynch, Tim; Healy, Daniel G; Moore, Helena; Walsh, Richard; Reilly, Richard B; O'Riordan, Seán; Walsh, Cathal Dominic; Hutchinson, Michael (Frontiers Media, 2015)
    Background: Adult-onset isolated focal dystonia (AOIFD) presenting in early adult life is more frequent in men, whereas in middle age it is female predominant. Temporal discrimination, an endophenotype of adult-onset ...
  • Lynch, Joseph; MacKenzie, Gilbert (IWSM, 2007)
    Kaplan-Meier analysis of a large breast cancer dataset is carried out under all-cause and cause-specific survival. The results are compared with a variety of model-based analyses, including Cox's Proportional Hazard ...
  • Faulkner, Fiona (University of Limerick, 2012)
    Declining standards in students’ mathematical competency levels has become a major issue in mathematics education both nationally and internationally (Smith 2004; Kajander and Lovric 2005; Gill et al 2010). This decline ...
  • Fennell, Peter G; Gleeson, James P.; Cellai, Davide (American Physical Society, 2014)
    Facilitated spin models were introduced some decades ago to mimic systems characterized by a glass transition. Recent developments have shown that a class of facilitated spin models is also able to reproduce characteristic ...
  • Gleeson, James P.; Melnik, Sergey (American Physical Society, 2009)
    An analytical approach to calculating bond percolation thresholds, sizes of k-cores, and sizes of giant connected components on structured random networks with nonzero clustering is presented. The networks are generated ...
  • Karpinski, Pawel; Szmida, Elzbieta; Misiak, Blazej; Ramsey, David; Leszczynski, Przemyslaw; Bebenek, Marek; Sedziak, Tomasz; Grzebieniak, Zygmunt; Jonkisz, Anna; Lebioda, Arleta; Sasiadek, Maria Malgorzata (Wiley, 2012)
    Background: Recent investigations have demonstrated the clear heterogeneity of sporadic colorectal cancer (CRC) with regard to CpG island methylation. Two unsupervised cluster analyses revealed that CRCs form three distinct ...
  • Dowd, Kieran P; Kirwan, Robert P; Hannigan, Ailish; Purtill, Helen; O'Gorman, Clodagh S (BMJ Publishing Group, 2015)
    Objectives: To examine the relationship between maternal self-reported and measured height and weight, maternal perceived weight status and measured body mass index (BMI), and maternal perceived child weight status and ...
  • Kane, M; Korn, B; Saukkonen, J; McDonald, C; Walsh, Cathal Dominic; Waters, R; McLaughlin, A.M; Keane, J (Irish Medical Organisation, 2013)
    Treatment of Latent Tuberculosis Infection (LTBI) is an important component of any TB control strategy. Acceptance and completion of treatment is poor. We undertook this study to identify barriers to acceptance & completion ...
  • 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, S; 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, A; Cellai, Davide; Gomez, S; Arenas, A; 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 ...
  • Devereux, Michael (University of Limerick, 2011)
    Foam and bubbles are ubiquitous in industry and nature. They have a wide range of applications but are also an undesirable product of certain processes. This thesis considers two individual industrial problems with the ...
  • Gil, Justyna; Ramsey, David; Stembalska, Agnieszka; Karpinski, Pawel; Pesz, Karolina A; Laczmanska, Izabela; Leszczynski, Przemyslaw; Grzebieniak, Zygmunt; Sasiadek, Maria Malgorzata (Springer-Verlag, 2012)
    Background: Epidemiological data show that colorectal cancer (CRC) is the second most frequent malignancy worldwide. The involvement of “minor impact genes” such as XME and DNA-repair genes in the etiology of sporadic ...
  • Hackett, Adam W. (University of Limerick, 2011)
    The network topologies on which many natural and synthetic systems are built provide ideal settings for the emergence of complex phenomena. One well-studied manifestation of this, called a cascade or avalanche, is observed ...
  • 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 ...

    While the pathogenesis of cervical dystonia remains unknown, recent animal and clinical experimental studies have indicated its probable mechanisms. Abnormal temporal discrimination is a mediational endophenotype of cervical ...
