  • Lynch, Joseph; MacKenzie, Gilbert (IWSM, 2011)
    We compare and contrast the properties of the bivariate Weibull and GTDL regression survival models. An analytic expression for the correlation between times is derived for the Weibull model and a modified Kullback-Lei ...
  • Benilov, Eugene (European Geosciences Union (EGU) International, 1999)
    The evolution of tracer "injected" into an equivalent barotropic eddy on the beta-plane is examined numerically. The eddy is governed by the standard quasigeostrophic equation, and the concentration of tracer is governed ...
  • Peng, Defen; MacKenzie, Gilbert (IWSM, 2007)
    We develop an analysis of the reliability of reliability data following a negative exponential distribution and subject to type I censoring. Our main focus is to determine the role of the particular analytical approach ...
  • Vynnycky, Michael; Saleem, S.; Devine, K .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 ...
  • Louzada-Neto, Francisco; MacKenzie, Gilbert; Cremasco, Caroline Pires; Ferreira-Silva, Paulo Henrique (UNESP, 2011)
    In order to accommodating crossing hazard curves, which are non- proportional hazards, we consider in this paper a generalized time-dependent logistic hazard survival model, which has a time-dependent term. The model is ...
  • Dassios, Ioannis K.; Cuffe, Paul; Keane, Andrew (2015)
    Electrical power system calculations rely heavily on the Y_{bus} matrix, which is the Laplacian matrix of the network under study, weighted by the complex-valued admittance of each branch. It is often useful to partition ...
  • Berkery, Elaine C.; Morley, Michael; Tiernan, Siobhán; Purtill, Helen; Parry, Emma (John Wiley and Sons Ltd., 2017)
    The aim of this study was to identify bundles of flexible working arrangements (FWAs) from data provided by 1,064 organizations in seven EU countries, and to relate bundle membership to demographic variables and human ...
  • Villiers, Rory (University of Limerick, 2011)
    The most common method of pricing a cashflow collateralized debt obligation (cashflow CDO) is to use Monte Carlo integration. However, Monte Carlo integration is computationally intensive and often faster methods of ...
  • Ramsey, David; Futschik, Andreas (IWSM, 2011)
    We consider the optimal pooling of DNA to detect single nucleotide polymorphisms (SNPs), sites along the genome at which a population shows variation. The focus is on the detection of low frequency variants. Pooling ...
  • McCormack, Jean; Casey, Vincent; Conway, Richard; Saunders, Jean; Perry, Alison (BioMed Central, 2015)
    Background: Commercially available tools for measuring oro-lingual pressures during swallowing or isometric (tongue 'pushing') tasks have either poor, or unknown, psychometric properties (stability, reliability) which means ...
  • Ramsey, David (Elsevier, 2012)
    A model of partnership formation based on two traits, called beauty and character, is presented. There are two classes of individual and partners must be of di erent classes. Individuals prefer prospective partners with ...
  • Alpern, S.; Katrantzi, I.; Ramsey, David (Elsevier, 2013)
    We analyze a model of partnership formation in which players’ preferences are based on the age of a prospective partner. There are two classes of individuals, called for convenience here male and female. Males and females ...
  • Tuite, H.; Horgan, Mary; Mallon, P.W.G.; McConkey, S.J.; Mooka, B.; Mulcahy, F.; Walsh, Cathal Dominic; O'Hora, A.; O'Flanagan, D.; Bergin, Colm; Fleming, C. (Irish Medical Organisation, 2015)
    This study describes the demographics and treatment status of HIV-infected adults accessing ambulatory care in the Republic of Ireland and estimates diagnosed HIV prevalence rates. 3254 HIV-infected adults attended 1 of ...
  • Benilov, Eugene; Benilov, M.S. (American Physical Society, 2019)
    An observation is presented that the ratio of the critical and triple-point temperatures T-cr/T-tp of neon, argon, krypton, and xenon fit within a narrow interval, T-cr/T-tp = 1.803 +/- 0.5%, and the same applies to the ...
  • Faqeeh, Ali (University of Limerick, 2016)
    Many of the systems we observe in nature, in societies, or in infrastructures are in the form of a network of interacting units. This underlying network structure shapes the behavior of such systems and is an indispensable ...
  • Cellai, Davide; López, Eduardo; Zhou, Jie; Gleeson, James P.; Bianconi, Ginestra (American Physical Society, 2013)
    From transportation networks to complex infrastructures, and to social and communication networks, a large variety of systems can be described in terms of multiplexes formed by a set of nodes interacting through different ...
  • O'Rourke, K.; Berge, E.; Walsh, Cathal Dominic; Kelly, P.J. (The Cochrane Collaboration. Published by John Wiley & Sons, Ltd, 2010)
    Most disabling strokes are due to blockage of a large artery in the brain by a blood clot. Prompt removal of the clot with intra-arterial thrombolytic drugs or mechanical devices, or both, can restore blood flow before ...
  • Blagojevic, Milica; MacKenzie, Gilbert (IWSM, 2004)
    We generalize the previously developed Non-PH CTDL-Gamma and the PH Weibull-Gamma frailty models to correlated survival data. In particular, we seek analytical results using the marginal approach, to determine whether ...
  • Fowler, Andrew C. (Springer, 2019)
    In this paper we revisit the problem of explaining phase transition by a study of a form of the Boltzmann equation, where inter-molecular attraction is included by means of a Vlasov term in the evolution equation for the ...
  • Karpinski, Pawel; Myszka, Aleksander; Ramsey, David; Misiak, Blazej; Gil, Justyna; Laczmanska, Izabela; Grzebieniak, Zygmunt; Sebzda, Tadeusz; Smigiel, Robert; Stembalska, Agnieszka; Sasiadek, Maria Malgorzata (Elsevier, 2010)
    The CpG island methylator phenotype (CIMP), together with extensive promoter methylation, is regarded as one of the mechanisms involved in colorectal carcinogenesis (CRC). The mechanisms underlying the presence of CIMP in ...
