Objective: The aim of the present study was to investigate if high amplitude frequency oscillations (haHFOs) could be a biomarker posttraumatic epileptogenesis. Methods: After an initial craniotomy rats and inducement traumatic brain injury (TBI) through fluid percussion, recording microelectrodes were implanted bilaterally in different areas. Wideband electric...

Dynamic systems are faced with large vibration amplitudes if they operate near the resonance frequency of system or while passing through resonance. With a suitable external excitation reduction amplitude oscillation can be achieved. The analysis variable was first carried out on force driven single degree freedom harmonic oscillator. influence various parameters seen after mathematical transfo...

Abstract Background The vestibular system can perceive sound at high intensity levels. recording of evoked myogenic potentials (VEMPs) is one the clinical techniques that capture when activated by sound. In healthy individuals, it has been demonstrated VEMP thresholds are lower using low-frequency stimuli, particularly 500 Hz tone burst. Aging affects frequency tuning, causing shift to higher f...

Complex mechanical systems usually include nonlinear interactions between their components which can be modeled by equations describing the sophisticated motion of system. In order to interpret dynamics these systems, it is necessary compute more precisely frequencies. The vibration process a conservative oscillator always follows law energy conservation. A variational formulation constructed a...
