Charged particle interaction with a chirped electromagnetic pulse [PDF]

open access: yes, 2003
It is found that a charged particle can get a net energy gain from the interaction with an electromagnetic chirped pulse. Theoretically, the energy gain increases with the pulse amplitude and with the relative frequency variation in the ...

Task-evoked pulse wave amplitude tracks cognitive load

open access: yesScientific Reports, 2023
Cognitive load is a crucial factor in mentally demanding activities and holds significance across various research fields. This study aimed to investigate the effectiveness of pulse wave amplitude (PWA) as a measure for tracking cognitive load and ...

Relationship Between Asperities and Velocity Pulse Generation Mechanism

open access: yesFrontiers in Earth Science, 2022
Near-fault ground motion records often capture instances of pulse-like behavior, where a burst of energy is expressed as large wave amplitude that occur over short time.

Ocular pulse amplitude after trabeculectomy [PDF]

open access: yesGraefe's Archive for Clinical and Experimental Ophthalmology, 2005
The ocular pulse amplitude (OPA) is the difference between the minimum and maximum values of the pulsatile intraocular pressure (IOP) wave contour. The OPA depends on ocular perfusion and IOP, which are both affected by a trabeculectomy (TE). The aim of this study was to investigate how the OPA changes after TE and whether an early change in OPA can be

Discrete Fourier Transform Windowing Techniques for Cerebral Physiological Research in Neural Injury: A Practical Demonstration

open access: yesNeurotrauma Reports, 2023
To optimally assess oscillatory phenomena within physiological variables, spectral domain transforms are used. A discrete Fourier transform (DFT) is one of the most common methods used to attain this spectral change.

Cerebrospinal fluid pulse pressure amplitude during lumbar infusion in idiopathic normal pressure hydrocephalus can predict response to shunting

open access: yesCerebrospinal Fluid Research, 2010
Background We have previously seen that idiopathic normal pressure hydrocephalus (iNPH) patients having elevated intracranial pressure (ICP) pulse amplitude consistently respond to shunt surgery.

Time-resolved optical gating based on dispersive propagation: a new method to characterize optical pulses [PDF]

open access: yes, 2000
We introduce the technique of time-resolved optical gating (TROG) based on dispersive propagation (DP), a new noninterferometric method for characterizing ultrashort optical pulses in amplitude and phase without the need for a short optical gating pulse.
