Abstract: Polarization and Depolarization Current (PDC) technique is an effective tool to assess the condition of oil-paper insulation system in power transformers. So far the PDC behaviors of mineral ...

Abstract: Perfusion index (PI), the ratio between variable pulsatile (AC) and non-pulsatile (DC) components in a photoplethysmographic (PPG) signal, is an indirect and non-invasive measure of ...

Spreading depression, discovered by Leao in 1944, 1 is an intense depolarization wave that slowly propagates (≈3 mm/min) in gray matter by way of contiguity, regardless of functional divisions or ...

The human brain constantly adapts in response to experiences, forming new connections between neurons and reorganizing ...

Spreading depolarizations (SDs) are recurrent and ostensibly spontaneous depolarization waves that may contribute to infarct progression after stroke. Somatosensory activation of the metastable ...
