  • Erkol, Şirag; Faqeeh, Ali; Radicchi, Filippo (IOP Publishing, 2018)
    We consider the problem of identifying the most influential nodes for a spreading process on a network when prior knowledge about structure and dynamics of the system is incomplete or erroneous. Specifically, we perform a ...
  • 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). ...
  • Moroney, Kevin M.; Lee, William T.; O'Brien, Stephen B.G.; Suijver, F.; Marra, Johan (Society for Industrial and Applied Mathematics, 2016)
    Extraction of coffee solubles from roast and ground coffee is a highly complex process, depending on a large number of brewing parameters. We consider a recent, experimentally validated, model of coffee extraction, describing ...
  • Cuffe, Paul; Dassios, Ioannis K.; Keane, Andrew (IEEE Computer Society, 2016)
    Abstract—Loss minimizing generator dispatch profiles for power systems are usually derived using optimization techniques. However, some authors have noted that a system’s KGL matrix can be used to analytically determine ...

M.; Howard, Robert; Pasquier, Florence; Borjesson-Hanson, Anne; Tsolaki, Magda; Lucca, Ugo; William Molloy, D; Coen, Robert; Riepe, Matthias W.; Kálmán, János; Kenny, Rose Anne; Cregg, Fiona; O'Dwyer, Sarah; Walsh, Cathal Dominic; Adams, Jessica; Banzi, Rita; Breuilh, Laetitia; Daly, Leslie; Hendrix, Suzanne; Aisen, Paul; Gaynor, Siobhan; Sheikhi, Ali; Taekema, Diana G.; Verhey, Frans R.; Nemni, Raffaello; Nobili, Flavio; Franceschi, Massimo; Frisoni, Giovanni; Zanetti, Orazio; Konsta, Anastasia; Anastasios, Orologas; Nenopoulou, Styliani; Tsolaki-Tagaraki, Fani; Pakaski, Magdolna; Dereeper, Olivier; de la Sayette, Vincent; Sénéchal, Olivier; Lavenu, Isabelle; Devendeville, Agnés; Calais, Gauthier; Crawford, Fiona; Mullan, Michael (Public Library of Science, 2018)
    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 ...
  • Leahy, Joe; O'Leary, Aisling; Afdhal, Nezam; Gray, Emma; Milligan, Scott; Wehmeyer, Malte H.; Walsh, Cathal Dominic (Wiley and Sons Ltd, 2018)
    The use of individual patient data (IPD) in network meta-analysis (NMA) is becoming increasingly popular. However, as most studies do not report IPD, most NMAs are performed using aggregate data for at least some, if not ...
  • Lynch, Julie; Prihodova, Lucia; Dunne, Pádraic J.; O'Leary, Caoimhe; Breen, Rachel; Carroll, Áine; Walsh, Cathal Dominic; McMahon, Geraldine; White, Barry (BMJ Publishing Group, 2018)
    Objectives Rates of burnout and stress in healthcare practitioners are steadily increasing. Emergency department (ED) staff are particularly susceptible to such poor outcomes. Mantra meditation (MM) may contribute to ...
  • Lee, William T.; Kaar, S.; O'Brien, Stephen B.G. (American Assocation of Physics Teachers, 2018)
    A surprising phenomenon witnessed by many is the sinking bubbles seen in a settling pint of stout beer. Bubbles are less dense than the surrounding fluid so how does this happen? Previous work has shown that the explanation ...
  • Ambartsoumian, G.; Felea, R.; Krishnan, V.P.; Nolan, Clifford J.; Quinto, E.T. (2018)
    In this article, we consider two bistatic cases arising in synthetic aperture radar imaging: when the transmitter and receiver are both moving with different speeds along a single line parallel to the ground in the same ...
  • Faqeeh, Ali; Osat, Saeed; Radicchi, Filippo (American Physical Society, 2018)
    We show that the community structure of a network can be used as a coarse version of its embedding in a hidden space with hyperbolic geometry. The finding emerges from a systematic analysis of several real-world and ...
  • Warmenhoven, John; Harrison, Andrew J.; Robinson, Mark J.; Vanrenterghem, Jos; Bargary, Norma; Smith, Richard; Cobley, Stephen; Draper, Conny; Donnelly, Cryil; Pataky, Todd (Elsevier, 2018)
    Objectives: To examine whether the Functional Data Analysis (FDA), Statistical Parametric Mapping (SPM) and Statistical non-Parametric Mapping (SnPM) hypothesis testing techniques differ in their ability to draw inferences ...
  • Zeglinski, Jacek; Kuhs, Manuel; Khamar, Dikshitkumar; Hegarty, Avril C.; Devi, Renuka K.; Rasmuson, Åke C. (Wiley and Sons Ltd, 2018)
    The influence of the solvent in nucleation of tolbutamide, a medium-sized, flexible and polymorphic organic molecule, has been explored by measuring nucleation induction times, estimating solvent-solute interaction ...
  • Semochkina, Daria A. (University of Limerick, 2018)
    This thesis is concerned with the calibration of disease models in order to inform decisions about public health problems. These models are used to make predictions about the likely outcomes of disease spread (e.g. ...
  • Ryan, Veronica (University of Limerick, 2018)
    This research study investigated student performance in mathematics during the transition from primary to post-primary school. Academic achievement in mathematics was measured using a standardised test at the end of sixth ...
  • O'Keeffe, Gary J. (University of Limerick, 2018)
    Solar-thermal collectors capture solar energy and convert it into heat energy. Several types of solar-thermal collectors have been used to harness solar radiation in both residential, electricity generation, and industrial ...

    Background: Network meta-analysis (NMA) allows for the estimation of comparative effectiveness of treatments that have not been studied in head-to-head trials; however, relative treatment effects for all interventions can ...

  • MacKenzie, Gilbert; Al-tawarah, Yasin; Blagojevic, Milisa; Burke, Kevin (IWSM, 2018)
    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 ...
  • Peng, Defen; Burke, Kevin; MacKenzie, Gilbert (IWSM, 2018)
    The Weibull multi-parameter regression (MPR) model with frailty is developed for interval censored survival data. The basic MPR model which is wholly parametric with non-proportional hazards was developed by Burke ...
  • Vo, Tuoi T.N.; Morgan, Sarah; McCormick, Christopher; McGinty, Sean; McKee, Sean; Meere, Martin (Elsevier, 2018)
    Traditional coronary drug-eluting stents (DES) are made from metal and are coated with a permanent polymer film containing an anti-proliferative drug. Subsequent to stent deployment in a diseased coronary artery, the drug ...
