Spontaneous activity in the waiting brain: A marker of impulsive choice in attention-deficit/hyperactivity disorder?

open access: yesDevelopmental Cognitive Neuroscience, 2015
Background: Spontaneous very low frequency oscillations (VLFO), seen in the resting brain, are attenuated when individuals are working on attention demanding tasks or waiting for rewards (Hsu et al., 2013).

Workload estimation of handwriting tasks using time series of pen pressure

open access: yesNihon Kikai Gakkai ronbunshu, 2020
Pen comfort is an important factor in selection of pen for handwriting. In handwriting, a pen receives an impact when it contacts to paper placed on a desk. To hold the pen, fingers have to resist the impact.

Impulse Oscillometry

open access: yesAdvances in Respiratory Medicine, 2019
Pulmonary function testing involves a battery of tests from the simple pulse oximetry to the cardiopulmonary exercise testing. Impulse oscillometry (IOS) is one of the newly described pulmonary function tests. It is based on the old principle of forced oscillatory technique modified and refined as per research and advances. It involves the use of sound
