Subthreshold electric fields bidirectionally modulate neurotransmitter release through axon polarization [PDF]

Brain Stimulation
Background: Subthreshold electric fields modulate brain activity and show promise in several therapeutic applications. Although therapeutic electric fields are often uniform at the cellular level, they generate non-uniform membrane polarization within ...

Quantitative Correlation between Adsorbed and Condensed Water Mass with Response Galvanic Current Detected at the Micron Gap of Galvanic-Coupled Arrays

Chemosensors, 2022
Sensor surfaces with micron- and nano-gap scales possess high surface-to-volume ratio which greatly affects their contribution towards water adsorption and condensation.

Cryosurgery with pulsed electric fields. [PDF]

PLoS ONE, 2011
This study explores the hypothesis that combining the minimally invasive surgical techniques of cryosurgery and pulsed electric fields will eliminate some of the major disadvantages of these techniques while retaining their advantages.

Law of Electric fields via Bianchi identities

Journal of Applied Science and Engineering, 2022
we define a second-order tensor E of rank 2 for the electric flux called the electric flux tensor and obtain the law of electric fields in the space-time system with respect to any frame of reference, using Bianchi identities of Riemannian Geometry ...

Polariton Electric-Field Sensor [PDF]

Physical Review Letters, 2020
We experimentally demonstrate a dipolar polariton based electric field sensor. We tune and optimize the sensitivity of the sensor by varying the dipole moment of polaritons. We show polariton interactions play an important role in determining the conditions for optimal electric field sensing, and achieve a sensitivity of 0.12 V-m$^{-1}$-Hz$^{-0.5 ...

Hypoxic preconditioning promotes galvanotaxis of human dermal microvascular endothelial cells through NF-κB pathway

Heliyon, 2022
Angiogenesis plays an important role in wound healing, especially in chronic wound. The directional migration of the human dermal microvascular endothelial cells (HDMECs) is the key regulation of angiogenesis.

Nowcasting and Validating Earth's Electric Field Response to Extreme Space Weather Events Using Magnetotelluric Data: Application to the September 2017 Geomagnetic Storm and Comparison to Observed and Modeled Fields in Scotland

Space Weather, 2021
In the United Kingdom, geomagnetically induced currents (GICs) are calculated from thin‐sheet electrical conductivity models. In the absence of conductivity models, time derivatives of magnetic fields are sometimes used as proxies for GIC‐related ...
