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 ... -
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 ... -
Indoor air quality, thermal comfort and ventilation in deep energy retrofitted Irish dwellings
(Elsevier, 2022-05-28)Residential building stock energy retrofits will play a key role in EU climate actions. The impact of these retrofits on indoor air quality (IAQ) and occupant comfort needs to be assessed to inform future renovation ... -
Interference method for determination of the refractive index and thickness
(Society of Photo-optical Instrumentation Engineers, 2000-09-01)The interference method for simultaneous measurement of the absolute refractive index and the thickness of plane parallel samples is developed. This method enables us to test solid (including optical glasses, crystals, ... -
An investigation into the use of MMCTP to tune accelerator source parameters and testing its clinical application.
(2013)This paper presents an alternative method to tune Monte Carlo electron beam parameters to match measured data using a minimal set of variables in order to reduce the model setup time prior to clinical implementation of the ... -
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 ... -
Investigation of nanoscale structural alterations of cell nucleus as an early sign of cancer
(BioMed Central, 2014)Background: The cell and tissue structural properties assessed with a conventional bright-field light microscope play a key role in cancer diagnosis, but they sometimes have limited accuracy in detecting early-stage cancers ... -
An investigation of the Eigenvalue Calibration Method (ECM) using GASP for non-imaging and imaging detectors
(Springer Verlag, 2016-02)Polarised light from astronomical targets can yield a wealth of information about their source radiation mechanisms, and about the geometry of the scattered light regions. Optical observations, of both the linear and ... -
Investigations of the magnetospheric plasma distribution in the vicinity of a pulsar - I Basic formulation
(2008)The magnetospheric plasma distribution in the vicinity of a pulsar at various inclination angles is investigated using a new relativistic, parallel 3D Particle-In-Cell (PIC) code DYMPHNA3D. DYMPHNA3D uses a superposition ... -
The invisible barrier to safe textile recycling
(Frontiers Media, 2022-06-14)Presence of certain chemical additives (e.g. halogenated flame retardants, perfluoroalkyl substances, and phthalates) could hinder textile recycling operations as their presence renders end-of-life materials as “hazardous” ... -

The June 2008 flare of Markarian 421 from optical to TeV energies
(2008)We present optical, X-ray, high energy ($\lessapprox 30$ GeV) and very high energy ($\gtrapprox 100$ GeV; VHE) observations of the high-frequency peaked blazar Mrk 421 taken between 2008 May 24 and June 23. A high energy ... -
Kinematics of the Broad Line Region in M81
(2007)A new model is presented which explains the origin of the broad emission lines observed in the LINER/Seyfert nucleus of M81 in terms of a steady state spherically symmetric inflow, amounting to 1 x 10^-5 Msun/yr, which is ... -
Label free ultra-sensitive imaging with sub-diffraction spatial resolution
(IEEE, 2019-07-09)In this paper, we show a new way to break the resolution limit and dramatically improve sensitivity to structural changes. To realize it we developed a novel label free contrast mechanism, based on the spectral encoding ... -
Label-free ultra-sensitive visualization of structure below the diffraction resolution limit
(Wiley, 2018-03-23)For both fundamental study of biological processes and early diagnosis of diseases, information about nanoscale changes in tissue and cell structure is crucial. Nowadays, almost all currently known nanoscopy methods rely ... -
Leaching of decabromodiphenyl ether and hexabromocyclododecane from fabrics under simulated landfill conditions
(KeAi Communications Co. Ltd, 2019-12-30)A series of laboratory experiments were conducted to examine the leaching of decabromodiphenyl ether (BDE-209) and hexabromocyclododecane (HBCDD) from a mix of three fabrics. Consistent with previous reports that such ... -
Microcirculation imaging based on full-range high-speed spectral domain correlation mapping optical coherence tomography
(SPIE (International Society for Optics and Photonics, 2014)Microcirculation imaging is a key parameter for studying the pathophysiological processes of various disease conditions, in both clinical and fundamental research. A full-range spectral-domain correlation mapping optical ... -
Microscopic particle discrimination using spatially-resolved Fourier-holographic light scattering angular spectroscopy
