  • 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 ...
  • Lane, Ciara; Stynes, Martin; O'Donoghue, John (2013)
    A questionnaire survey was conducted as part of a PhD study investigating post-primary students' images of mathematics in Ireland. A definition of image of mathematics was adopted from Lim (1999) and Wilson (2011). ...
  • Dassios, Ioannis K. (Elsevier, 2018)
    In this article, we focus on a generalized problem of linear non-autonomous fractional nabla difference equations. Firstly, we define the equations and describe how this family of problems covers other linear fractional ...
  • Peng, Defen; MacKenzie, Gilbert (IWSM, 2011)
    Recently, several advances have been made in the analysis of interval censored (IC) data mainly in relation to semi-parametric proportional hazard (PH) models (Gómez et al., 2009, Lesaffre et al., 2005). It is arguable, ...
  • Dassios, Ioannis K.; Fountoulakis, Kimon; Gondzio, Jacek (Society for Industrial and Applied Mathematics, 2016)
    In this paper we are concerned with the solution of Compressed Sensing (CS) problems where the signals to be recovered are sparse in coherent and redundant dictionaries. We extend the primal-dual Newton Conjugate Gradients ...
  • Hurley, Julie (University of Limerick, 2011)
    One of the most controversial and innovative finnancial products in recent years has been collateralised debt obligations (CDOs). Much of the blame for the current credit crisis is being attributed to the mathematical models ...
  • Zeglinski, Jacek; Kuhs, Manuel; Devi, Renuka K.; Khamar, Dikshitkumar; Hegarty, Avril C.; Thompson, Damien; Rasmuson, Åke C. (American Chemical Society, 2019)
    Induction time experiments, spectroscopic and calorimetric analysis, and molecular modelling were used to probe the influence of solvent on the crystal nucleation of fenoxycarb (FC), a medium-sized, flexible organic ...
  • Moyles, Iain R.; Fowler, Andrew C. (Springer, 2018)
    Nitrification at the site of a contaminant ammonium plume from a former coal carbonisation plant can be modelled with three competing bacterial populations of Nitrosomonas, Nitrobacter, and Brocadia anammoxidans. Oscillations ...
  • Kiri, Victor A (Maney Publishing, 2012)
    Pharmacoepidemiological studies based on the cohort design are simpler to analyse and their results easier to interpret. However, these may not reflect real-life drug use which is a major strength of such studies. The ...
  • Prendergast, Mark (University of Limerick, 2011)
    In 2010, figures show that only 45 per cent of Irish students took Higher Level mathematics for the Junior Certificate examination and only 16 per cent took Higher Level mathematics for the Leaving Certificate examination ...
  • Laczmanska, Izabela; Karpinski, Pawel; Bebenek, Marek; Sedziak, Tomasz; Ramsey, David; Szmida, Elżbieta; Sasiadek, Maria Malgorzata (Nature Publishing Group, 2013)
    Introduction: The activity of phosphatases could be influenced by genetic, as well as epigenetic alterations. In our study we have investigated the methylation status of four PTPRs: PTPRM, PTPRT, PTPRR and PTPRZ1, which ...
