An O(a) modified lattice set-up of the Schrödinger functional in SU(3) gauge theory
(2011)The set-up of the QCD Schrödinger functional (SF) on the lattice with staggered quarks requires an even number of points L/a in the spatial directions, while the Euclidean time extent of the lattice, T/a, must be odd. ... -
Obesity and Employment in Ireland: Moving Beyond BMI
(ESRI, 2012)I use data from the first wave of the Irish Longitudinal Study on Ageing (TILDA) to investigate the impact of obesity on the labour market status of older Irish individuals. I employ an anthropometric indicator of body ... -

Objective Assessment of Perceptual Audio Quality Using ViSQOLAudio
(2017)Digital audio broadcasting services transmit substantial amounts of data that is encoded to minimize bandwidth whilst maximizing user quality of experience. Many large service providers continually alter codecs to improve ... -
An objective framework for determination of the air-entry value from the soil?water characteristic curve
(2021)The air-entry value (AEV) suction, marking the transition between saturated and unsaturated soil mechanics, is arguably the most important parameter interpreted from the soil–water characteristic curve (SWCC); its accurate ... -
Objective Sleep Duration in Older Adults: Results From The Irish Longitudinal Study on Ageing
(Wiley, 2020)Objective: This study assessed the distribution and correlates of objective sleep duration in the older population in Ireland. Design: Cross-sectional study using population-derived data from wave 3 of The Irish Longitudinal ... -

Observation of a new interference phenomena in internal conical diffraction
(2015)Conical diffraction is observed in biaxial materials when a beam of light is directed along one of the two optic axis directions. When the beam is directed close to but not along an optic axis, a rich interference pattern ... -
Observation of an anchoring transition in a discotic liquid crystal
(EDP Sciences, 1998)We report the anchoring transition in a discotic liquid crystal, hexapentyloxytriphenylene (HPT), from edge-on to side-on alignment in a discotic phase. The topology, easy direction of orientation and the coating of the ... -
observation of an anomalous SmA-SmC-SmA phase sequence in a bent-core liquid crystal derived from 4-cyanoresorcinol
(2020)The physical properties and the phase transitions of a smectic liquid crystal material built from achiral bent-core molecules are investigated by electro-optics, polarizing microscopy, birefringence, and spontaneous ... -
Observation of antiferromagnetic coupling in epitaxial ferrite films
(2006)Defects in ferrite can change the local magnetic coupling from ferromagnetic to strongly antiferromagnetic. In eptiaxial magnetite (Fe3O4) films, defects locally altering exchange interaction, i.e., ?antiphase boundaries? ... -
Observation of intermultiplet transitions in Sm(Fe11Ti) by inelastic neutron scattering
(American Physical Society, 1990)Magnetic neutron spectroscopy of SMFe11Ti reveals a dispersionless electronic excitation corresponding to transitions between levels of the exchange-split ground- and first-excited-state multiplets of the Sm3+ ion. The ... -
Observation of magnetic domains using a reflection-mode scanning near-field optical microscope
(American Institute of Physics, 1997)It is demonstrated that it is possible to image magnetic domains with a resolution of better than 60 nm with the Kerr effect in a reflection-mode scanning near-field optical microscope. Images taken of tracks of ... -
Observation of nonradiative energy transfer in the excitation of Nd3+ in GaP
(American Physical Society, 1990)We have carried out luminescence-excitation measurements on a Nd3+ complex in GaP in the range 1.5?2.2 eV to determine the mechanisms by which the internal Nd3+ luminescence is generated. At low temperatures we observe ... -
Observation of surface states within the stop-bands of a photonic crystal slab with asymmetric termination

An observational overview of solar flares
(2011)We present an overview of solar flares and associated phenomena,drawing upon a wide range of observational data primarily from the RHESSI era. Following an introductory discussion and overview of the status of observational ...
