Previous studies have shown conflicting results on the effect of lung volume on the diaphragm compound muscle action potential (CMAP). Consequently, the ability to quantify the oesophageal diaphragm electromyography (EMG) has been questioned. If lung volume changes have little effect on the diaphragm CMAP the accurate measurement of voluntary EMG, as an index of respiratory drive, may be possib...

A major goal of neuroscience is to understand the functions of networks of neurons in cognition and behavior. Recent work has focused on implanting arrays of ∼100 immovable electrodes or smaller numbers of individually adjustable electrodes, designed to target a few cortical areas. We have developed a recording system that allows the independent movement of hundreds of electrodes chronically im...

Objectives: Postoperative atrial fibrillation (POAF) is a frequent complication following cardiac surgery. This study examined the safety and efficacy of new DefiPaceTM system consisting two bi-atrial temporary pacing cardioversion electrodes, ventricular electrode device (combined external pacemaker cardioverter) for low-energy cardioversion. Methods: The electrodes were placed on left right a...

We propose an unconventional type of Hall effect in a topological Dirac semimetal with ferromagnetic electrodes. The itself has time-reversal symmetry, whereas attached electrodes break it, causing the large response. This induced is characteristic helical surface/edge states that arise materials such as semimetals or quantum spin insulators. compute conductance/resistance and angle by using la...

Cardiovascular diseases (CVDs) are the leading cause of death worldwide. Therefore, ability to monitor electrocardiogram (ECG) in long term could save patients’ lives by allowing early diagnosis and intervention. Dry electrodes best option accomplish this task. 3D printing is one popular techniques currently used construct dry electrodes. This project designs, builds, tests, compares printed EC...

Recent phylogenetic analyses of tribe Neillieae in Rosaceae, which comprises Neillia, Physocarpus, and Stephanandra, based on both nuclear and chloroplast DNA sequences revealed that Neillia and Stephanandra together form a strongly supported monophyletic group and that species of Stephanandra are nested within Neillia. The close relationship between Neillia and Stephanandra is also supported b...

We present a self-consistent Schrödinger–Poisson scheme for simulation of electrostatic quantum dots defined in gated two-dimensional electron gas formed at n-AlGaAs /GaAs heterojunction. The computational method is applied to a quantitative description of transport properties studied experimentally by Elzermann et al. Appl. Phys. Lett. 84, 4617 2004 . Our three-dimensional model describes the ...
