  • Bahey-El-Din, Mohammed; Griffin, Brendan T.; Gahan, Cormac G. (BioMed Central, 2008-07)
    Background: Listeria monocytogenes is a well-characterized food-borne pathogen that infects pregnant women and immunocompromised individuals. Listeriolysin O (LLO) is the major virulence factor of the pathogen and is often ...
  • Harte, Seán; Popovici, Emanuel M.; O'Flynn, Brendan (WSEAS Press, 2008-07)
    This research focuses on the design and implementation of a tool to speed-up the development and deployment of heterogeneous wireless sensor networks. The THAWS (Tyndall Heterogeneous Automated Wireless Sensors) tool can ...
  • Bandi, Thejesh N.; Minogin, V. G. (Vladimir Georgievich), 1950-; Nic Chormaic, Síle (American Physical Society, 2008-07)
    We propose and present a quantitative analysis of neutral atom microtraps based on optical near fields produced by the diffraction of a laser wave on small apertures in a thin screen. We show that near-field atom microtraps ...
  • Kohlas, Juerg; Wilson, Nic (Elsevier, 2008-07)
    Local computation in join trees or acyclic hypertrees has been shown to be linked to a particular algebraic structure, called valuation algebra. There are many models of this algebraic structure ranging from probability ...
  • Wilson, Nic (Elsevier, 2008-08)
    Linear constraints occur naturally in many reasoning problems and the information that they represent is often uncertain. There is a difficulty in applying AI uncertainty formalisms to this situation, as their representation ...
  • O'Mahony, Caitlin; Scully, Paul; O'Mahony, David; Murphy, Sharon; O'Brien, Frances; Lyons, Anne; Sherlock, Graham; MacSharry, John; Kiely, Barry; Shanahan, Fergus; O'Mahony, Liam (PLOS, 2008-08-01)
    Host defence against infection requires a range of innate and adaptive immune responses that may lead to tissue damage. Such immune-mediated pathologies can be controlled with appropriate T regulatory (Treg) activity. The ...
  • Rohan, James F.; Casey, Declan P.; Ahern, Bernadette M.; Rhen, Fernando M. F.; Roy, Saibal; Fleming, David; Lawrence, Simon E. (Elsevier, 2008-09)
    We present a novel technique for the preparation of coaxial metal and magnetic alloy nanotubes, which is demonstrated for the coaxial nanotubes of Ni/Co and Ni/CoNiFe alloys deposited in activated polycarbonate templates ...
  • Harte, Seán; Popovici, Emanuel M.; O'Flynn, Brendan; Ó Mathúna, S. Cian (World Scientific and Engineering Academy and Society, 2008-09)
    This research focuses on the design and implementation of a tool to speed-up the development and deployment of heterogeneous wireless sensor networks. The THAWS (Tyndall Heterogeneous Automated Wireless Sensors) tool can ...
  • Cotter, Paul D.; Draper, Lorraine A.; Lawton, Elaine M.; Daly, Karen M.; Groeger, David S.; Casey, Pat G.; Ross, R. Paul; Hill, Colin (PLOS, 2008-09-12)
    Streptolysin S (SLS) is a bacteriocin-like haemolytic and cytotoxic virulence factor that plays a key role in the virulence of Group A Streptococcus (GAS), the causative agent of pharyngitis, impetigo, necrotizing fasciitis ...
  • Cronin, Michelle A.; Sleator, Roy D.; Hill, Colin; Fitzgerald, Gerald F.; Sinderen, Douwe van (BioMed Central Ltd., 2008-09-24)
    Background: Probiotics such as bifidobacteria have been shown to maintain a healthy intestinal microbial balance and help protect against infections. However, despite these benefits, bifidobacteria still remain poorly ...
  • Watson, Debbie; Sleator, Roy D.; Hill, Colin; Gahan, Cormac G. (BioMed Central, 2008-10)
    The majority of commensal gastrointestinal bacteria used as probiotics are highly adapted to the specialised environment of the large bowel. However, unlike pathogenic bacteria; they are often inadequately equipped to ...
  • Ryan, Kieran A.; Jayaraman, Thevaraajan; Daly, Paul; Canchaya, Carlos; Curran, Susan; Fang, Fang; Quigley, Eamonn M.; O'Toole, Paul W. (Society for Applied Bacteriology; Blackwell Publishing, 2008-10)
    Aims: Recent evidence suggests that the human gastric microbiota is much more diverse than previously thought. The aim of this study was to assess the potential for isolating lactobacilli from the human stomach.Methods and ...
  • Wang, Ningning; O'Donnell, Terence; Meere, Ronan; Rhen, Fernando M. F.; Ó Mathúna, S. Cian; Roy, Saibal (Institute of Electrical and Electronics Engineers, 2008-11)
    This paper presents a microinductor fabricated on silicon using electrochemical techniques that has high efficiency in a low power dc–dc converter. Small signal measurements show a flat frequency response up to 20 MHz with ...
  • Heck, Susannah C. (University College Cork, 2009)
    Quantum dashes are elongated quantum dots. Polarized edge-photovoltage and spontaneous emission spectroscopy are used to study the anisotropy of optical properties in 1.5μm InGaAsP and AlGaInAs-based quantum dash lasers. ...
  • Špinar, Rostislav; Muthukumaran, Panneer; de Paz, Rodolfo; Pesch, Dirk; Song, Weiping; Chaudhry, Shafique Ahmad; Sreenan, Cormac J.; Jafer, Essa; O'Flynn, Brendan; O'Donnell, James; Costa, Andrea; Keane, Marcus M. (2009)
    Existing Building/Energy Management Systems (BMS/EMS) fail to convey holistic performance to the building manager. A 20% reduction in energy consumption can be achieved by efficiently operated buildings compared with ...
  • O'Dwyer, Colm; Lavayen, Vladimir; Tanner, David A.; Newcomb, Simon B.; Benavente, Eglantina; Gonzalez, Guillermo; Sotomayor Torres, Clivia M. (Wiley, 2009)
    The relationship between the nanoscale structure of vanadium pentoxide nanotubes and their ability to accommodate Li+ during intercalation/deintercalation is explored. The nanotubes are synthesized using two different ...
  • Walsh, Michael; O'Flynn, Brendan; Barton, John; Ó Mathúna, S. Cian (IEEE, 2009)
