Characterising glyphosate exposures among amenity horticulturists using multiple spot urine samples
(Elsevier, 2018-07-08)Background Glyphosate has recently received much public attention following its Group 2A probably carcinogenic to humans classification from the International Agency for Research on Cancer. Despite the widespread ... -
Performance review of multiple reference versus time domain optical coherence tomography
(IEEE, 2018-04-19)We present a detailed characterization of noise sources in multiple reference optical coherence tomography (MR-OCT) compared to time-domain OCT (TD-OCT). The noise characteristics were modeled based on the TD-OCT noise ... -
Pilot study to investigate indoor air quality (IAQ) in energy efficient homes in Ireland: Report prepared for EPA STRIVE and Sustainable Energy Authority of Ireland
(School of Physics, NUI Galway, 2010-09)Within this pilot study a number of Indoor air pollutants were measured in five energy efficient homes built to enhanced standards of air tightness of between 0.75 m3 /hr/m2 and 8.75 m3 /hr/m2 . The five homes were ... -
Indoor air quality and thermal comfort in Irish retrofitted energy efficient homes
(School of Physics, NUI Galway, 2017-03-14)Results from an Irish study comparing the concentrations of 10 indoor air pollutants and occupant comfort in 15 naturally ventilated three bed semi-detached two storey homes before and after the implementation of energy ... -
Investigation of depth-resolved nanoscale structural changes in regulated cell proliferation and chromatin decondensation
(2013)We present depth-resolved spatial-domain low-coherence quantitative phase microscopy, a simple approach that utilizes coherence gating to construct a depth-resolved structural feature vector quantifying sub-resolution axial ... -
Sophisticated clean air strategies required to mitigate against particulate organic pollution
(Nature Publishing Group, 2017-03-17)Since the 1980's, measures mitigating the impact of transboundary air pollution have been implemented successfully as evidenced in the 1980-2014 record of atmospheric sulphur pollution over the NE-Atlantic, a key region ... -
Top-down and bottom-up aerosol-cloud closure: towards understanding sources of uncertainty in deriving cloud shortwave radiative flux
(European Geosciences Union (EGU), 2017-08-22)Top-down and bottom-up aerosol-cloud shortwave radiative flux closures were conducted at the Mace Head Atmospheric Research Station in Galway, Ireland, in August 2015. This study is part of the BACCHUS (Impact of Biogenic ... -
Experimental and numerical assessment of MRI-induced temperature change and SAR distributions in phantoms
(Springer Verlag, 2017-06)During an MR procedure, most of the transmitted RF power is transformed into heat within the patient’s tissue and implants as a result of resistive losses which is referred to as the specific energy absorption rate (SAR) ... -
Understanding the changes of cone reflectance in adaptive optics flood illumination retinal images over three years
(Optical Society of America, 2016)Although there is increasing interest in the investigation of cone reflectance variability, little is understood about its characteristics over long time scales. Cone detection and its automation is now becoming a fundamental ... -

Performance analysis of cone detection algorithms
(Optical Society of America, 2015-04-01)Many algorithms have been proposed to help clinicians evaluate cone density and spacing, as these may be related to the onset of retinal diseases. However, there has been no rigorous comparison of the performance of these ... -
The study of neutron star magnetospheres with LOFT
(2015)The Large Observatory for X-ray Timing, LOFT, is designed to perform fast X-ray timing and spectroscopy with uniquely large throughput (Feroci et al. 2014). LOFT focuses on two fundamental questions of ESA’s Cosmic Vision ... -
In vivo correlation mapping microscopy
(Society of Photo-optical Instrumentation Engineers (SPIE), 2016-03)To facilitate regular assessment of the microcirculation in vivo, noninvasive imaging techniques such as nailfold capillaroscopy are required in clinics. Recently, a correlation mapping technique has been applied to optical ... -
A recent change in the optical and gamma ray polarization of the Crab nebula and pulsar
(Oxford journals, 2015-12-31)We report on observations of the polarization of optical and γ-ray photons from the Crab nebula and pulsar system using the Galway Astronomical Stokes Polarimeter (GASP), the Hubble Space Telescope, Advanced Camera for ... -
Unprecedented study of the broadband emission of Mrk 421 during flaring activity in March 2010
(EDP Sciences, 2015-05-27)Context. Because of its proximity, Mrk 421 is one of the best sources on which to study the nature of BL Lac objects. Its proximity allows us to characterize its broadband spectral energy distribution (SED). Aims. The ... -
The 2009 multiwavelength campaign on Mrk 421: variability and correlation studies
(EDP Sciences, 2015-04-17)Aims. We perform an extensive characterization of the broadband emission of Mrk 421, as well as its temporal evolution, during the non-flaring (low) state. The high brightness and nearby location (z = 0.031) of Mrk 421 ... -
