Precession aided magnetic stochastic resonance in ferromagnetic nanoparticles with cubic anisotropy
(American Physical Society, 2005)It is shown that the signal-to-noise ratio in the magnetic stochastic resonance of single-domain ferromagnetic nanoparticles having cubic anisotropy exhibits a strong intrinsic dependence on the decay rate a of the ... -
Precessional effects in the linear dynamic susceptibility of uniaxial superparamagnets: Dependence of the ac response on the dissipation parameter
(American Physical Society, 2001)It is shown that the low-frequency relaxation spectrum of the linear dynamic susceptibility of uniaxial single domain particles with a uniform magnetic field applied at an oblique angle to the easy axis can be used ... -
Preparation and characterisation of metallorganic precursors derived iron oxides on porous silicon layers
(Trans Tech Publications Ltd., Switzerland, 2020)Porous silicon has generated interest in scientific community after its photoluminescence discovery and thereafter, research was focused on to the chemical functionalization of silicon and subsequent anchoring of nanoparticles ... -
The Price of Ignorance: Distributed Topology Control in Cognitive Networks
(2010)In a cognitive network, autonomous and adaptive radios select their operating parameters to achieve individual and network-wide goals. The effectiveness of these adaptations depends on the amount of knowledge about the ... -
Principles of cognitive network teamwork
(2006)This paper looks ahead at the future of wireless communications systems that can combine their resources and capabilities in order to enhance their overall ability to collect and convey information. Cognitive network teamwork ... -
Probe Contact Force Monitoring during Conductivity Measurements of the Left Atrial Appendage to Support the Design of Novel Diagnostic and Therapeutic Procedures
(2022)The electrical properties of many biological tissues are freely available from the INRC and the IT’IS databases. However, particularly in lower frequency ranges, few studies have investigated the optimal measurement protocol ... -
Propagation of an electromagnetic wave in an absorbing anisotropic medium and infrared transmission of liquid crystals: Comparison with experiments
(2009)The theory of the absorbance of a semi-infinite medium characterized by a second-rank dielectric tensor for the entire electromagnetic spectrum, as given by Scaife and Vij [J. Chem. Phys. 122, 174901 (2005)], is extended ... -
Propagation of an electromagnetic wave in an absorbing anisotropic medium and infrared transmission spectroscopy of liquid crystals
(2005)The theory of absorbance is developed for the entire electromagnetic spectrum of radiation in a semi-infinite anisotropic medium with a second rank dielectric tensor, the elements of which are complex and frequency dependent. ... -
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 ... -
