Relationship between Surface and Indwelling EMG Spike Shape Measures
… it inappropriate for monitoring human movement. Spike shape analysis of the surface electromyographic signal responds to the call for non-invasive EMG measures for monitoring human movement and detecting neuromuscular disorders. The present study analyzed the relationship between surface and …

Effects of isometric elbow flexion on electromyographic spike analysis
… between surface electromyographic (SEMG) spike activity and force. The secondary objective was to determine to what extent subcutaneous tissue impacts the high frequency component of the signal, as well as, examining the relationship between measures of SEMG spike shape and their …

Ion beam mixing of Mo/Al bilayer samples and thermal spike effects
… the interface was considered in terms of thermal spike induced atomic migration. It was found that the coupling of the chemical effect with spike is significant with regard to mixing of the bilayer samples. Furthermore, in addition to the initial contamination of carbon atoms on the surface and at …

Computer simulation of high fluence ion beam surface modification processes
… into account collisional mixing and thermal spike effects, as well as the thermal spike shape. The ion beam mixing parameter for the thermal spike is derived as being proportional to different powers of the damage parameter, i.e. the damage energy scaled by the cohesive energy of the matrix, …

Flowfield measurements in the vortex wake of a missile at high angle of attack in turbulence
… asymmetric vortices can be noted by the sharp spike shape in the ambient condition; this condition becomes diffused and becomes fatter in the turbulent condition; 2) The right side vortex has greater strength than the left side one as seen by the diffusion in the total pressure coefficient and …

On neural spike sorting with mixture models
… problem we are trying to solve is called neural spike sorting in literature. There are three basic objectives of spike sorting. The first is to estimate the number of neurons which contribute to the recorded neural data. The second is to identify the spikes, i.e. the little curves in the recorded …

A modeling study of the history-dependence of conduction delay in unmyelinated axons
… different ionic currents on conduction delay and spike shape parameters (i.e., duration, trough and peak voltages) with realistic burst stimulation protocols. Specifically, we found that only INa substantially affects the variability of conduction delay. Based on this observation, in the second …

Signal Modeling and Data Reduction for Wireless Brain-Machine Interfaces
… recordings for the validation of algorithms for spike detection and spike sorting. Having set up the geometry of the recording, each neuron is assigned a random spike waveforms from a library of experimentally obtained templates. The contribution of each neuron is generated by adding the …
