Journal ArticleDOI
Coupling bio-logging with nutritional geometry to reveal novel insights into the foraging behaviour of a plunge-diving marine predator
Gabriel E. Machovsky-Capuska,David Priddel,Philip Hw Leong,Peter Jones,Nicholas Carlile,Lesley Shannon,Dean Portelli,Alistair McEwan,Alexandre V. Chaves,David Raubenheimer +9 more
TL;DR: Females provided more food to their chicks than the males and, regardless of the nutritional variability of prey consumed, both sexes showed similar amounts of protein and lipid in their diets.
Journal ArticleDOI
Identification of a suitable current waveform for acute stroke imaging
TL;DR: The purpose of this work was to find the most suitable current pattern that could be employed in MFEIT measurements in the adult head with the UCLH Mk2.5 system, which applies currents from 20 Hz-1.6 MHz.
Journal ArticleDOI
Evaluation of a multi-electrode bioimpedance spectroscopy tensor probe to detect the anisotropic conductivity spectra of biological tissues
Bishal Karki,Hun Wi,Alistair McEwan,Alistair McEwan,Hyeuknam Kwon,Tong In Oh,Eung Je Woo,Jin Keun Seo +7 more
TL;DR: The current pattern for localized electrical energy concentration, performance with the spring loaded pin electrodes, data calibration and experimental results on anisotropic agar phantoms and different tissue types are described.
Journal ArticleDOI
A Local Region of Interest Imaging Method for Electrical Impedance Tomography with Internal Electrodes
Hyeuknam Kwon,Alistair McEwan,Alistair McEwan,Tong In Oh,Adnan Farooq,Eung Je Woo,Jin Keun Seo +6 more
TL;DR: A local ROI imaging method with internal electrodes developed from careful analysis of the sensitivity matrix is proposed that convincingly shows an improvement in local sensitivity in images obtained with an internal electrode in comparison to a standard reconstruction method.
Journal ArticleDOI
Code-Division-Multiplexed Electrical Impedance Tomography Spectroscopy
TL;DR: The method described provides images and spectra which are equivalent to the conventional time-multiplexed method, with increases in frequency resolution and measurement speed which may be of benefit in some applications of electrical impedance tomography spectroscopy.
