Individualized frequency and montage tACS to engage theta-gamma coupling and enhance working memory in mild cognitive impairment [PDF]

Frontiers in Psychiatry
Mild Cognitive Impairment (MCI) is a clinical prodromal stage of Alzheimer’s disease. Enhancing executive functions in patients with MCI could optimize cognitive compensatory mechanisms and slow cognitive decline.

Phase-dependent modulation of the vestibular–cerebellar network via combined alternating current stimulation influences human locomotion and posture

Frontiers in Neuroscience, 2022
BackgroundHuman locomotion induces rhythmic movements of the trunk and head. Vestibular signaling is relayed to multiple regions in the brainstem and cerebellum, and plays an essential role in maintaining head stability.

The new analytical expression for measurement uncertainty in a measuring of RMS value of AC signals as result of non ideal synchronization [PDF]

Serbian Journal of Electrical Engineering, 2006
Synchronous sampling allows alternating current (AC) quantities, such as the root mean square (RMS) values of voltage and power, to be determined with very low uncertainties (on the order of a few parts of 10-6 [1]). In this a new mathematical expression

Impact of MV Standards on Shipboard DC Cable System Size

IEEE Open Access Journal of Power and Energy, 2022
There is rising interest in medium-voltage direct current (MVDC) power systems for several reasons, including compatibility with DC loads and avoidance of alternating current (AC) frequency synchronization issues when combining multiple source outputs ...

Effects of alternating current stimulation on the healthy and diseased brain

Frontiers in Neuroscience, 2015
Cognitive and neurological dysfunctions can severely impact a patient’s daily activities. In addition to medical treatment, non-invasive transcranial alternating current stimulation (tACS) has been proposed as a therapeutic technique to improve the ...

Electro-osmotic flow of generalized Maxwell fluids in triangular microchannels based on distributed order time fractional constitutive model

AIP Advances, 2023
Based on the linearized Poisson–Boltzmann equation, the electro-osmotic flow of a generalized Maxwell fluid under an alternating field in an isosceles right triangle microchannel is studied.
