• Acid polishing of lead glass 

  Ward, Jonathan A; Fowler, Andrew C (SpringerOpen, 2016)

  Purpose: The polishing of cut lead glass crystal is effected through the dowsing of the glass in a mixture of two separate acids, which between them etch the surface and as a result cause it to be become smooth. In order ...
• Coffee extraction kinetics in a well mixed system 

  Moroney, Kevin M; Lee, William T.; O'Brien, Stephen BG; Suijver, Freek; Marra, Johan (SpringerOpen, 2016)

  The extraction of coffee solubles from roasted and ground coffee is a complex operation, the understanding of which is key to the brewing of high quality coffee. This complexity stems from the fact that brewing of coffee ...

  Livingstone, Stephen J; Utting, Daniel J; Ruffell, Alastair; Clark, Chris D; Pawley, Steven; Atkinson, Nigel; Fowler, Andrew C (Nature Publishing Group, 2016)

  Recent proxy measurements reveal that subglacial lakes beneath modern ice sheets periodically store and release large volumes of water, providing an important but poorly understood influence on contemporary ice dynamics ...

  Usher, Cara; Adams, Roisin; Schmitz, Susanne; Kieran, Jennifer; O'Flanagan, Darina; O'Donnell, Joan; Connolly, Kevin; Corcoran, Brenda; Butler, Karina; Barry, Michael; Walsh, Cathal Dominic (BioMed Central, 2016)

  Background: The aim of this study was to compare the cost effectiveness of the current Irish programme of universal BCG vaccination of infants versus a programme which considered selectively vaccinating high risk ...
• Effects of network structure, competition and memory time on social spreading phenomena 

  Gleeson, James P.; O'Sullivan, Kevin P; Banos, Ranquel, A; Moreno, Yamir (American Physical Society, 2016)

  Online social media has greatly affected the way in which we communicate with each other. However, little is known about what fundamental mechanisms drive dynamical information flow in online social systems. Here, we ...
• Bond percolation on multiplex networks 

  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 ...
• A preconditioner for a primal-dual Newton conjugate gradients method for compressed sensing problems 

  Dassios, Ioannis; 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 ...
• The association between maternal perceptions of own weight status and weight status of her child: results from a national cohort study 

  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 ...
• Psychosocial Interventions for Problem Alcohol Use in Primary Care Settings (PINTA): baseline feasibility data. 

  Klimas, Jan; Henihan, Anne Marie; McCombe, Geoff; Swan, Davina; Anderson, Rolande; Bury, Gerard; Dunne, Colum; Keenan, Eamon; Saunders, Jean; Williams Shorter, Gillian; Smyth, Bobby P; Cullen, Walter (Taylor and Francis, 2015)

  Objectives. Primary care is a key provider of long-term care for people who attend primary care for substance use treatment, especially those in methadone maintenance treatment. As many drink alcohol excessively, there is ...
• The formation of river channels 

  Fowler, Andrew C; Kopteva, Natalia; Oakley, Charles (Society for Industrial and Applied Mathematics, 2006)

  We consider a deterministic model of landscape evolution through the mechanism of overland flow over an erodible substrate, using the St. Venant equations of hydraulics together with the Exner equation for hillslope erosion. ...
• Waves in Guinness 

  Robinson, Marguerite; Fowler, Andrew C; Alexander, A.J; O'Brien, S.B.G (American Institute of Physics, 2008)

  We describe a simple model of a bubbly two-phase flow which is able to explain why waves propagate downward when a pint of Guinness is poured, and also how the waves are generated. Our theory involves a physically based ...
• The morphology of the Martian ice caps: a mathematical model of ice-dust kinetics 

  Zammett, R.J; Fowler, Andrew C (Society for Industrial and Applied Mathematics, 2010)

  Spiral-shaped canyons on the polar ice caps of Mars are striking morphological features whose explanation is still mysterious. We pose a model for the kinetics at the ice-atmosphere interface based on the positive feedback ...
• Subglacial hydrology as a control on emergence, scale, and spacing of ice streams 

  Kyrke-Smith, T.M; Katz, R.F; Fowler, Andrew C (American Geophysical Union, 2015)

  Observations have long associated ice streams with the presence of meltwater at the bed. More recently, theoretical models have been able to reproduce ice stream behavior as a consequence of the coupled dynamics of ice and ...
• Numerical studies of thermal convection with temperature-and pressure-dependent viscosity at extreme viscosity contrasts 

  Khaleque, Tania S; Fowler, Andrew C; Howell, P D; Vynnycky, M (American Institute of Physics, 2015)

  Motivated by convection of planetary mantles, we consider a mathematical model for Rayleigh-Benard convection in a basally heated layer of a fluid whose viscosity depends strongly on temperature and pressure, defined in ...
• Blowing of polycrystalline silicon fuses 

  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 ...
• Latent class analysis identification of syndromes in Alzheimer's disease: A Bayesian approach 

  Walsh, Cathal Dominic (Univerza v Ljubljani, Fakulteta za Druzbene Vede, 2006)

  Latent variable models have been used extensively in the social sciences. In this work a latent class analysis is used to identify syndromes within Alzheimer's disease. The fitting of the model is done in a Bayesian framework, ...
