Localised deflicker of moving images
(2006)Brightness fluctuations in sequences are a typical impairment in archive and modern footage. These fluctuations are mainly temporal but they may also present spatial variations across each individual frame. Current deflicker ... -
The localization of focal heart activity via body surface potential measurements: tests in a heterogeneous torso phantom
(2009)The non-invasive localization of focal heart activity via body surface potential measurements (BSPM) could greatly benefit the understanding and treatment of arrhythmic heart diseases. However, the in vivo validation of ... -
Localized relaxation in a glass and the minimum in its orientational polarization contribution
(American Institute of Physics, 2002)The dielectric permittivity and loss spectra of the glassy state of 5-methyl-2-hexanol obtained by quenching it from the liquid state has been studied. In one experiment, the spectra were studied at different temperatures ... -
Localized relaxation's strength and its mimicry of glass-softening thermodynamics.
(American Institute of Physics, 2002)The dielectric relaxation strength of the ? process, ???, in a rigid-molecular glass of 16.6 mol?% chlorobenzene cis-decalin mixture increases slowly with temperature, T, until the glass-softening range is reached, and ... -
Longitudinal complex magnetic susceptibility and relaxation time of superparamagnetic particles with cubic magnetic anisotropy
(American Physical Society, 1998)The magnetic relaxation of single-domain ferromagnetic particles with cubic magnetic anisotropy is treated by averaging the Gilbert-Langevin equation for an individual particle, so that the system of linear differential-recurrence ... -
Low-Complexity Equalization and Detection for OTFS-NOMA
(2023)Orthogonal time frequency space (OTFS) modula- tion has recently emerged as a potential 6G candidate waveform which provides improved performance in high-mobility scenarios. In this paper we investigate the combination ... -
Low-Complexity Joint CFO and Channel Estimation for RIS-aided OFDM Systems
(2021)Accurate channel estimation is essential for achieving the performance gains offered by reconfigurable intelligent surface (RIS)-aided wireless communications. A variety of channel estimation methods have been proposed ... -
Low-Complexity Reliability-Based Equalization and Detection for OTFS-NOMA
(2023)Orthogonal time frequency space (OTFS) modula- tion has recently emerged as a potential 6G candidate waveform which provides improved performance in high-mobility scenarios. In this paper we investigate the combination ... -
Macroscopic biaxiality and electric-field-induced rotation of the minor director in the nematic phase of a bent-core liquid crystal
(2010)Biaxiality in the nematic phase has been investigated for the bent-core liquid-crystal para-heptylbenzoate diester, using polarised IR spectroscopy. Anisotropic fluctuations of the nematic director are discussed in terms ... -
Magnetization dynamics of two interacting spins in an external magnetic field
(American Physical Society, 2005)The longitudinal relaxation time of the magnetization of a system of two exchange coupled spins subjected to a strong magnetic field is calculated exactly by averaging the stochastic Gilbert-Landau-Lifshitz equation for ... -
The MANIAC Challenge: Exploring MANETs through Competition
(2010-05)In this paper we discuss the MANIAC Challenge, a cooperative and competitive approach to MANET networking research. Our goal was to create an opportunity for researchers to come together and compete in a MANET-based ... -
Mapping theoretical and methodological perspectives for understanding speech interface interactions
(2019)The use of speech as an interaction modality has grown considerably through the integration of Intelligent Personal Assistants (IPAs- e.g. Siri, Google Assistant) into smartphones and voice based devices (e.g. Amazon Echo). ... -
MCMC for Joint Noise Reduction and Missing Data Treatment in Degraded Video
(2002)Image sequence restoration has been steadily gaining importance with the increasing prevalence of visual digital media. Automated treatment of archived video material typically involves dealing with replacement noise in ... -
The Me31B DEAD-Box Helicase Localizes to Postsynaptic Foci and Regulates Expression of a CaMKII Reporter mRNA in Dendrites of Drosophila Olfactory Projection Neurons.
(2010)mRNP granules at adult central synapses are postulated to regulate local mRNA translation and synapse plasticity. However, they are very poorly characterized in vivo. Here, in Drosophila olfactory synapses, we present early ... -
Measurement of phonemic degradation in sensorineural hearing loss using a computational model of the auditory periphery
