  • O'Brien, Joseph D.; Aleta, Alberto; Moreno, Yamir; Gleeson, James P. (American Physical Society, 2020)
    The Hawkes process has garnered attention in recent years for its suitability to describe the behavior of online information cascades. Here we present a fully tractable approach to analytically describe the distribution ...
  • Vynnycky, Michael; Masuda, Y (American Institute of Physics, 2013)
    The problem of fast viscous steady Rayleigh-Bénard convection in a rectangular enclosure is revisited using asymptotic and numerical methods. There are two generic cases: in the first, there is zero shear stress at all ...
  • Nicoletti, Sara; Fanelli, Duccio; Zagli, Niccolò; Asllani, Malbor; Battistelli, Giorgio; Carletti, Timoteo; Chisci, Luigi; Innocenti, Giacomo; Livi, Roberto (AIP Publishing, 2019)
    A stochastic reaction-diffusion model is studied on a networked support. In each patch of the network, two species are assumed to interact following a non-normal reaction scheme. When the interaction unit is replicated ...
  • Allen, Niamh; Brady, Melissa; Carrion Martin, Antonio Isidro; Domegan, Lisa; Walsh, Cathal Dominic; Doherty, Lorraine; Ni Riain, Una; Bergin, Colm; Fleming, Catherine; Conlon, Niall (Elsevier, 2021)
    Dear Editor, We write in response to correspondence from Whitaker et al. in this Journal (1). The authors demonstrate increases in seropositivity for SARS-CoV-2 antibodies against the spike protein as the roll out of ...
  • Davoren, Martin P.; Hayes, Kevin; Horgan, Mary; Shiely, Frances (BMJ Publishing Group, 2014)
    Objective The burden of sexually transmitted infections (STIs) rests with young people, yet in Ireland there has been very little research into this population. The purpose of this study was to determine the incidence ...
  • Lee, William T.; Kaar, Simon; 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 ...
  • Fowler, Andrew C.; McGuinness, Mark J. (Elsevier, 2019)
    We provide an analytic estimate for the size of the bulbs adjoining the main cardioid of the Mandelbrot set. The bulbs are approximate circles, and are associated with the stability regions in the complex parameter μ-space ...
  • Davis, Arran J.; MacCarron, Pádraig; Cohen, Emma (Public Library of Science, 2021)
    There is growing academic, civic and policy interest in the public health benefits of community-based exercise events. Shifting the emphasis from competitive sport to communal activity, these events have wide appeal. In ...
  • Cregan, Vincent; Lee, William T.; Clune, Louise (SpringerOpen, 2017)
    A soft sensor for measuring product quality in the Bayer process has been developed. The soft sensor uses a combination of historical process data recorded from online sensors and laboratory measurements to predict a key ...
  • Kartun-Giles, Alexander P.; Krioukov, Dmitri; Gleeson, James P.; Moreno, Yamir; Bianconi, Ginestra (MDPI, 2018)
    A projective network model is a model that enables predictions to be made based on a subsample of the network data, with the predictions remaining unchanged if a larger sample is taken into consideration. An exchangeable ...
  • O'Brien, Joseph D.; Dassios, Ioannis K.; Gleeson, James P. (IOP Publishing, 2019)
    A model for the spreading of online information or ‘memes’ on multiplex networks is introduced and analyzed using branching-process methods. The model generalizes that of (Gleeson et al 2016 Phys. Rev.X) in two ways. ...
  • Kyrke-Smith, T.M.; Katz, R.F; Fowler, Andrew C. (International Glaciological Society, 2013)
    One challenge in improving our understanding of ice-stream dynamics is to develop models of the spatial and temporal transition from ice-sheet to ice-stream flow. We address this with a new, vertically integrated, higher-order ...
  • 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 ...
  • Kyrke-Smith, T.M.; Fowler, Andrew C. (2014)
    The existence of both water and sediment at the bed of ice streams is well documented, but there is a lack of fundamental understanding about the mechanisms of ice, water and sediment interaction. We pose a model to describe ...
  • Asllani, Malbor; Siebert, Bram A.; Arenas, Alex; Gleeson, James P. (American Institute of Physics, 2022)
    The emergence of order in collective dynamics is a fascinating phenomenon that characterizes many natural systems consisting of coupled entities. Synchronization is such an example where individuals, usually represented ...
  • Muolo, Riccardo; Carletti, Timoteo; Gleeson, James P.; Asllani, Malbor (MDPI, 2021)
    Synchronization is an important behavior that characterizes many natural and human made systems that are composed by several interacting units. It can be found in a broad spectrum of applications, ranging from neuroscience ...
  • Schaller, Barbara E.; Moroney, Kevin M.; Castro-Dominguez, Bernardo; Cronin, Patrick; Belen-Girona, Jorge; Ruane, Patrick; Croker, Denise M.; Walker, Gavin M. (Elsevier, 2019)
    In this work, the transfer of oral solid dosage forms, currently manufactured via wet granulation, to a continuous direct compression process was considered. Two main challenges were addressed: (1) a poorly flowing API ...
  • Gleeson, James P.; Durrett, Rick (Nature Publishing Group, 2017)
    An avalanche or cascade occurs when one event causes one or more subsequent events, which in turn may cause further events in a chain reaction. Avalanching dynamics are studied in many disciplines, with a recent focus on ...
  • Gleeson, James P. (2009)
    The motion of overdamped particles in a one-dimensional spatially-periodic potential is considered. The potential is also randomly-fluctuating in time, due to multiplicative colored noise terms, and has a deterministic ...
  • McConnell, David; Hickey, Conor; Bargary, Norma; Trela-Larsen, Lea; Walsh, Cathal Dominic; Barry, Michael; Adams, Roisin (MDPI, 2021)
    SARS-CoV-2 continues to widely circulate in populations globally. Under detection is acknowledged and is problematic when attempting to capture the true prevalence. Seroprevalence studies, where blood samples from a ...
