High-resolution measurement of the unsteady velocity field to evaluate blood damage induced by a mechanical heart valve
(Springer, 2011-09)We investigate the potential of prosthetic heart valves to generate abnormal flow and stress patterns, which can contribute to platelet activation and lysis according to blood damage accumulation mechanisms. High-resolution ... -
High-resolution measurements of leakage flow inside the hinge of a large-scale bileaflet mechanical heart valve hinge model
(Springer, 2019-06-24)Purpose It is believed that non-physiological leakage flow through hinge gaps during diastole contributes to thrombus formation in Bileaflet Mechanical Heart Valves (BMHVs). Because of the small scale and difficulty of ... -
High-resolution measurements of leakage flow through bileaflet mechanical heart valve hinges
(2017-02-24)To restore proper function of the heart, diseased valves require repair or replacement. Mechanical heart valves are one of the treatments available. Despite their superior durability in comparison with biological prostheses, ... -
High-resolution multi-scale modelling of coastal flooding due to tides, storm surges and rivers inflows: A Cork city example
(Elsevier, 2017-01-31)This paper demonstrates the capability of a new state-of-the-art flood modelling system consisting of multiple nested models to simulate urban coastal flood inundation. A flood event in Cork City, Ireland which occurred ... -
High-resolution scanning electron microscopy for the analysis of three-dimensional ultrastructure of clots in acute ischemic stroke
(BMJ Publishing Group, 2020-12-23)Background: Characterization of acute ischemic stroke (AIS) clots has typically focused on two dimensional histological analysis of the thrombus. The three dimensional (3D) architecture and distribution of components ... -
High-resolution spectral domain optical coherence tomography system and structural characterization of ex vivo biological tissues using nanosensitive OCT
(NUI Galway, 2023-09-12)Optical Coherence Tomography (OCT) is a rapidly growing imaging modality which is based on the principle of low coherence interferometry. It can perform high-resolution, cross-sectional imaging of the microstructure of ... -
High-resolution ultrasound findings in the symptomatic residual limbs of amputees
(AMSUS, 2013-12-01)Introduction: Amputations are increasingly prevalent because of medical complications associated with diabetes, meningitis, peripheral vascular disease, and neoplasms as well as road traffic accidents and war. The use of ... -
High-resolution, wide-field object reconstruction with synthetic aperture Fourier holographic optical microscopy
(Optica, 2009)We utilize synthetic-aperture Fourier holographic microscopy to resolve micrometer-scale microstructure over millimeter-scale fields of view. Multiple holograms are recorded, each registering a different, limited region ... -
High-risk corneal transplantation: Recent developments and future possibilities
(Lippincott, Williams & Wilkins, 2019-12)Human corneal transplantation (keratoplasty) is typically considered to have superior short- and long-term outcomes and lower requirement for immunosuppression compared to solid organ transplants because of the inherent ... -
A high-speed bi-polar outflow from the archetypical pulsating star Mira A
(2009)Optical images and high-dispersion spectra have been obtained of the ejected material surrounding the pulsating AGB star Mira A. The two streams of knots on either side of the star, found in far ultra-viollet (FUV) GALEX ... -
High-speed, multicolour optical photometry of the anomalous x-ray pulsar 4u 0142+61 with ultracam
(Oxford University Press (OUP), 2005-10-21)We present high-speed, multicolour optical photometry of the anomalous X-ray pulsar 4U 0142+61, obtained with ULTRACAM on the 4.2-m William Herschel Telescope. We detect 4U 0142+61 at magnitudes of i' = 23.7 +/- 0.1, g' = ... -
High-strength thermoplastic bonding for multi-channel, multi-layer lab-on-chip devices for ocean and environmental applications
(Springer Nature, 2015-08-05)A solvent vapour thermoplastic bonding process is reported which provides high-strength bonding of PMMA over a large area for multi-channel and multi-layer microfluidic devices with shallow high-resolution channel features. ... -
High-throughput electrochemical microfluidic immunoarray for multiplexed detection of cancer biomarker proteins
(American Chemical Society (ACS), 2016-08-26)Microchip-based microfluidic electrochemical arrays hold great promise for fast, high-throughput multiplexed detection of cancer biomarker proteins at low cost per assay using relatively simple instrumentation. Here we ... -
High-throughput inference of protein-protein interfaces from unassigned nmr data
(Oxford University Press (OUP), 2005-06-01)One of the limiting factors in deciphering transcriptional regulatory networks is the effectiveness of motif-finding software. An emerging avenue for improving motif-finding accuracy aims to incorporate generalized binding ... -
High-throughput metabolic genotoxicity screening with a fluidic microwell chip and electrochemiluminescence
(Royal Society of Chemistry (RSC), 2013-01-01)A high throughput electrochemiluminescent (ECL) chip was fabricated and integrated into a fluidic system for screening toxicity-related chemistry of drug and pollutant metabolites. The chip base is conductive pyrolytic ... -
High-time Resolution Astrophysics and Pulsars
(2008)The discovery of pulsars in 1968 heralded an era where the temporal characteristics of detectors had to be reassessed. Up to this point detector integration times would normally be measured in minutes rather seconds and ... -
Higher order dynamic inequalities on time scales
(Element d.o.o., 2014-01-01)In this paper, we will prove some new dynamic inequalities of higher orders on time scales. The results contain some continuous and discrete inequalities as special cases. We will prove the results by making use of Holder's ... -

Higher torsion in the Abelianization of the full Bianchi groups
(Cambridge University Press (Cambridge Journals Online), 2013-09)Denote by Q(root-m), with m a square-free positive integer, an imaginary quadratic number field, and by O-m its ring of integers. The Bianchi groups are the groups SL2(O-m). In the literature, so far there have been no ... -
