The rationale of this study was to investigate if the bases of generation of the electrical activity of the whole gut are the same. For this reason, we developed a mathematical dipole model, based on the same foundations used to simulate the electrical activity of the human stomach, to generate the electrical activity of the transverse cat colon. The model developed takes into account both the ...

A sensor is developed for simple, in situ characterization of dielectric thermal interface materials (TIMs) at bond line thicknesses less than 100 lm. The working principle is based on the detection of regions of contrasting electric permittivity. An array of long, parallel electrodes is flush-mounted into each opposing substrate face of a narrow gap interface, and exposed to the gap formed bet...

Networks of protoplasmic tubes of organism Physarum polycehpalum are macro-scale structures which optimally span multiple food sources to avoid repellents yet maximize coverage of attractants. When data are presented by configurations of attractants and behaviour of the slime mould is tuned by a range of repellents, the organism preforms computation. It maps given data configuration into a prot...

The feasibility of electrotherapy with low level direct current for cancer treatment was tested on fibrosarcoma SA-I and malignant melanoma B-16 experimental tumor models. Treatment was performed with Pt/lr electrodes inserted into the solid tumors and subcutaneously in the vicinity of the tumors, with currents ranging from 0.6 to 1.8 mAo Regardless of the electrode polarity or electrode config...

The research described here includes work on fabrication techniques for reproducible thin-film electrodes. Runs with these electrodes in a newly fabricated high sensitivity calorimetry bank is shown to provide added support for earlier excess heat production observed with ultra-high proton loadings in thin film electrodes. In addition, new in-situ radiation emission studies have discovered MeV ...

BACKGROUND Recording surface electromyogram (EMG) signals from sphincter muscles has become of increasing interest due to potential applications in diagnosis or investigation of the mechanisms of incontinence. Recently developed probes allow high-resolution detection of EMG signal from the external anal sphincter. One of the main issues in the interpretation of experimental signals is the detec...

Analytical self-energies for molecular interfaces with one-dimensional, tight-binding semiconductors are derived, along with analytical solutions to the electrode eigensystems. These models capture the fundamental differences between the transport properties of metals and semiconductors and also account for the appearance of surface states. When the models are applied to zero-temperature electr...

We present the site-selective, parallel and reproducible formation of conductive gold and tetrathiafulvalene-gold (TTF-Au) hybrid micro- and nanowires from their respective ion salt and cation-radical solutions. While the formation of micro- and nanowires by means of dielectrophoresis with directly coupled electrodes has been thoroughly investigated in recent studies, we present here the first ...

This paper presents an optimal design for a new humidity sensor composed of a dual-resonator oscillator configuration with an operation frequency of 300 MHz, and a polyaniline (PANI) coating deposited along the resonation cavity of the sensing device. To improve the corrosion resistance of the sensor chip, Al/Au electrodes were used to form the SAW resonator. Prior to device fabrication, the co...

We designed a novel 6-point electrochemical impedance spectroscopy (EIS) sensor with 15 combinations of permutations for the 3-D mapping and detection of metabolically active atherosclerotic lesions. Two rows of 3 stretchable electrodes circumferentially separated by 120° were mounted on an inflatable balloon for intravascular deployment and endoluminal interrogation. The configuration and 15 p...
