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

open access: yesFrontiers 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.

Transcranial alternating current stimulation over multiple brain areas with non-zero phase delays other than 180 degrees modulates visuospatial working memory performance

open access: yesScientific Reports, 2023
While zero-phase lag synchronization between multiple brain regions has been widely observed, relatively recent reports indicate that systematic phase delays between cortical regions reflect the direction of communications between cortical regions.

Fronto-parietal theta high-definition transcranial alternating current stimulation may modulate working memory under postural control conditions in young healthy adults

open access: yesFrontiers in Human Neuroscience, 2023
Objects This study aimed to investigate the immediate effects of fronto-parietal θ HD-tACS on a dual task of working memory-postural control. Methods In this within-subject cross-over pilot study, we assessed the effects of 20 min of 6 Hz-tACS targeting ...

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

open access: yesSerbian 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

open access: yesIEEE 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 ...

Selective modulation of interhemispheric connectivity by transcranial alternating current stimulation influences binaural integration

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2021
Significance Sensory processing depends upon the integration of widely distributed neural assemblies. During every day listening, our ears receive different information (due to interaural time and amplitude differences) and it is known that both ...

Effects of alternating current stimulation on the healthy and diseased brain

open access: yesFrontiers 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 ...

Frame Synchronization for Next Generation Uplink Coding in Deep Space Communications [PDF]

open access: yes, 2015
In this paper we develop two new approaches for frame synchronization in the binary-input AWGN channel, in which we account for the sign ambiguity of the received symbols and exploit knowledge of an alternating sequence which precedes the synchronization

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

open access: yesAIP 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.
