Lunar Power Grid: Network Structure and Spontaneous Synchronization [PDF]

IEEE Access
Achieving stable synchronized operation in an alternating current power network is critical to the continuity and reliability of energy delivery. In this paper, we study a dynamic model for synchronization in the proposed power network which the National

Efficacy of Transcranial Alternating Current Stimulation (tACS) in Cognition and Memory in Patients with Mild Cognitive Impairement or Alzheimer’s Disease. A Systematic Review and Meta‐analysis of Randomized Controlled Trials [PDF]

Alzheimers Dement
Gamma desynchronization is an early pathophysiological event in Alzheimer’s disease with a disturbance in oscillation in the gamma frequency range 30‐80 Hz. This disruption was found to be directly related to the disease progression and severity.

Alternate computation of the unit vectors synthesis towards synchronization of current-controlled grid-tie converter for renewable power system: An embedded outlook

Engineering Science and Technology, an International Journal, 2021
Phase synchronization and frequency tracking are essential part of control unit design for the grid -tie power converter of the efficient energy conversion system. A robust but straightforward algorithm has been proposed here using a digital zero-crossing detector (ZCD) circuit. The ZCD is made to be vigorous by a D-latched based implementation against

Shared intentionality modulates interpersonal neural synchronization at the establishment of communication system

Communications Biology, 2023
Whether and how shared intentionality (SI) influences the establishment of a novel interpersonal communication system is poorly understood. To investigate this issue, we designed a coordinating symbolic communication game (CSCG) and applied behavioral ...

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.
