Quantitative 23Na-MRI: From Pre-Clinical to Clinical Practice
(2010)Quantitative 23Na-MRI (qNa-MRI) is a non-invasive technique which allows for measuring subtle changes in the Tissue Sodium Concentration (TSC) after ischaemic stroke. Although, an increase in TSC after stroke has been ... -
Quantum dot energy relaxation mediated by plasmon emission in doped covalent semiconductor heterostructures
(American Physical Society, 2007)The interaction between interface plasmons within a doped substrate and quantum dot electrons or holes has been theoretically studied in double heterostructures based on covalent semiconductors. The interface plasmon modes, ... -
Quantum effects in the Brownian motion of a particle in a double well potential in the overdamped limit.
(2009)Quantum effects in the noninertial Brownian motion of a particle in a double well potential are treated via a semiclassical Smoluchowski equation for the time evolution of the reduced Wigner distribution function in ... -
Radar, TV, and Cellular Bands: Which Spectrum Access Technique for Which Bands?
(2014)Opportunistic access has been considered by regu- lators for a number of different spectrum bands. In this paper, we discuss and qualitatively evaluate techniques used in the discovery of spectrum opportunities, also ... -
Radio transmitter fingerprinting: A steady state frequency domain approach
(IEEE, 2008)We present a novel technique for radio transmitter identification based on frequency domain characteristics. Our technique detects the unique features imbued in a signal as it passes through a transmit chain. We are the ... -
Raman and Fourier transform infrared study of substitutional carbon incorporation in rapid thermal chemical vapor deposited Si 1-x-yGexCy on (1 0 0) Si
(2010)We report on a detailed study of the dependence of the vibrational modes in rapid thermal chemical vapor deposited Si1?x?yGexCy films on the substitutional carbon concentration. Si1?x?yGexCy films were investigated using ... -
Raman investigation of different polytypes in SiC thin films grown by solid-gas phase epitaxy on Si (111) and 6H-SiC substrates
(2010)Raman spectroscopy was applied to investigate a series of SiC films grown on Si and 6HSiC substrates by a new method of solid gas phase epitaxy. During the growth characteristic voids are formed in Si at the SiC/Si ... -
Rapid Thermal Oxidation of Ge-rich Strained Layers
(IEEE, 2004)In this paper, we repolt for thejirsr time the electrical properties ofultrathin oxides grown using rapid thermal oxidation (RTO) on strained Ge-rich layers on relaxed-SiGe buffers. Rapid thermal oxidation on strained ... -
Real-time zero-day Intrusion Detection System for Automotive Controller Area Network on FPGAs
(2023)Increasing automation in vehicles enabled by in- creased connectivity to the outside world has exposed vulnerabilities in previously siloed automotive networks like controller area networks (CAN). Attributes of CAN such ... -
A reconfigurable platform for cognitive networks
(IEEE, 2007)By introducing self-awareness and computational intelligence to reconfigurable radio networks, cognitive networks are viewed as the key to a new generation of self-configuring, self-optimizing and self-healing communications ... -
Relaxation strength of localized motions in D. Sorbitol and mimicry of glass-softening thermodynamics
(American Institute of Physics, 2003)The dielectric relaxation strength, ??JG, the relaxation rate, fm,JG and the distribution parameter, ?JG, of the faster relaxation process in D-sorbitol have been studied as a function of temperature and the cooling rate. ... -
Relaxation time for nonlinear response of a Brownian particle subject to a step external force: Analytical solutions for one-dimensional models
(American Physical Society, 1997)The nonlinear response to a step external force of a system with relaxational dynamics governed by a one-dimensional Fokker-Planck equation is considered. An exact analytical expression for the step response nonlinear ... -
Relaxations and nano-phase-separation in ultraviscous heptanol-alkyl halide mixture
(2007)To gain insight into the effects of liquid-liquid phase separation on molecular relaxation behavior we have studied an apparently homogeneous mixture of 5-methyl-2-hexanol and isoamylbromide by dielectric spectroscopy over ... -
Removal of line artefacts for digital dissemination of archived film and video
(IEEE, 1999)Line scratches are a common form of degradation in archived motion picture film. The automatic restoration of such, material has become of increasing interest in the last few years with the rase of consumer digital video ... -
Rendezvous for Cognitive Radios
(2011)Cognitive radios have been touted as a solution to communicating in a Dynamic Spectrum Access environment. This paper examines how cognitive radios initially find one another among the expanse of ever-changing open spectrum, ... -
The resonance decay function method in the determination of the pre-factor of the neel relaxation time of single-domain nanoparticles
(Elsevier, 2011)In its simple form, the relaxation time of the Neel relaxation process of the magnetic moment of single-domain particles is given by ?N=?0Nexp(?), ? being the ratio of the anisotropy energy to thermal energy. The pre-factor, ... -
Resource Allocation for Mixed Numerology NOMA
(2021)6G wireless networks will require the flexibility to accommodate an extremely diverse set of service types. Accommodating different quality of service (QoS) requirements for these service types necessitates the use of mixed ...
