The Role of Voltage-Gated Sodium Channels in Pain Signaling.
Physiological Reviews, 2019 Acute pain signaling has a key protective role and is highly evolutionarily conserved. Chronic pain, however, is maladaptive, occurring as a consequence of injury and disease, and is associated with sensitization of the somatosensory nervous system ...

Charging models for airborne suspended particles around HVDC lines
High Voltage, 2021 Ground total electric field (GTEF) is a vital parameter in the field of electromagnetic environment of high voltage direct current (HVDC) lines. Some experimental works reported that airborne suspended particles can be charged in the corona ion flow of ...

Electrical Treeing of SiR and SiR/Fe3O4 Nanocomposites in High Magnetic Field
IEEE Access, 2023 This paper investigates the effects of high magnetic field on electrical treeing of silicone rubber (SiR). Experimental results show that electrical trees are more easily to be initiated and spread further along the direction of electric field under the ...

Generalised voltage graphs [PDF]
European Journal of Combinatorics, 2021 A graph with a semiregular group of automorphisms can be thought of as the derived cover arising from a voltage graph. Since its inception, the theory of voltage graphs and their derived covers has been a powerful tool used in the study of graphs with a significant degree of symmetry.

Power cable stresses caused by transmission line faults in next generation VSC-MMC systems
The Journal of Engineering, 2019 Until today, HVDC systems based on Modular Multilevel Voltage Source Converters (VSC-MMC) have exclusively been realised with cross-linked polyethylene (XLPE) cable transmission in monopolar configuration.
