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 inaccuracy reported via the Manufacturer and User Facility Device Experience database for an implantable pulmonary artery pressure sensor: recalibration direction and magnitude results
(2024)INTRODUCTION: Remote monitoring using an implantable pulmonary artery pressure (PAP) sensor (CardioMEMS HF system) in patients with heart failure (HF) has been consistently shown to reduce HF hospitalizations [1]. The ... -
Measurement of phonemic degradation in sensorineural hearing loss using a computational model of the auditory periphery
(2009)A computational model of the auditory periphery enables faster investigation of new signal processing algorithms for hearing aids. This paper presents a study of the degradation of auditory nerve (AN) responses at a ... -
The Measurement of Spatially-Dependant Tissue Sodium Concentration Increase in a Rodent MCAO Stroke Model
(2009)The aim of this study was to accurately quantify changes in the Tissue Sodium Concentration (TSC) in the acute phase of a rodent stroke model with high spatio-temporal resolution (0.38mm3 / 10min) at 7T. The ability to ... -
Measurement of the polarization profile across a surface-stabilized ferroelectric liquid crystal cell using the pyroelectric laser-intensity-modulation method
(American Institute of Physics, 2003)The pyroelectric technique, called the laser-intensity-modulation method, was used for investigations of the spatial distribution of the pyroelectric coefficient that gives information about the director profile in ... -
Mechanical load cell based on cavity-controlled microwave oscillators
(IEEE, 1991)A device consisting of a rectangular resonator to which two oscillators are coupled at right angles to each other is described. The frequency of each oscillator is controlled by the cavity, and distortions caused by ... -
Mechanism of field-induced unwinding of SmC* helix and biasfield dependencies of dielectric permittivity and effective polarization
(2008)We propose an unwinding model based on helical fractures confirmed by spectroscopic and microscopic observations. This model combined with the fixed helical pitch can explain the various physical phenomena observed in ... -
A method for source-microphone range estimation in reverberant environments, using an array of microphones of unknown relative position
(IEEE, 2006)Estimating the range between an acoustic source and a microphone is a central problem in microphone-array processing. Although many approaches have been proposed in the literature, these tend to require knowledge of the ... -
A Method of Proactive MANET Routing Protocol Evaluation Applied to the OLSR Protocol
(2011)Traditional evaluation studies of MANET routing protocols have concentrated on quantitative, traffic-based metrics like throughput and packet loss. These metrics provide a lim- ited evaluation of protocol performance ... -
Micro-Raman and spreading resistance analysis on bevelled implanted germanium for layer transfer applications
(2011)Raman and spreading resistance profiling have been used to analyze defects in germanium caused by hydrogen and helium implants, of typical fluences used in layer transfer applications. Beveling has been used to facilitate ... -
Microscopic models for dielectric relaxation in disordered systems
(American Physical Society, 2004)It is shown how the Debye rotational diffusion model of dielectric relaxation of polar molecules (which may be described in microscopic fashion as the diffusion limit of a discrete time random walk on the surface of ... -
Microsecond linear optical response in the unusual nematic phase of achiral bimesogens
(2011)Some hydrocarbon linked mesogenic dimers are known to exhibit an additional nematic phase (N(x)) below a conventional uniaxial nematic (N(u)) phase. Although composed of non-chiral molecules, the N(x) phase is found to ... -
Microstructural investigation supporting an abrupt stress induced transformation in amorphous carbon films
(American Institute of Physics, 2009)The intrinsic stress of carbon thin films deposited by filtered cathodic arc was investigated as a function of ion energy and Ar background gas pressure. The microstructure of the films was analyzed using transmission ... -
