The aim of this paper is to present an experimental validation of a frequency-domain approach to the solution of the lightning electromagnetic field-to-buried cable coupling equations. The coupling to the inner conductor is evaluated using the concept of cable transfer impedance. The theoretical model and relevant computer code are tested using experimental data on lightning-induced currents in...

This paper presents the study of induced currents and temperature distribution in gear heated by induction process using 2D finite element (FE) model. The model is developed by coupling Maxwell and heat transfer equations into a multi-physics model. The obtained results allow comparing the medium frequency (MF) and high frequency (HF) cases and the effect of machine parameters on the evolution ...

Hydroxylamine (HA) is a putative intermediate in the conversion of l-arginine to nitric oxide (NO). HA was reported to cause the relaxation of precontracted aorta strips; however, the ionic mechanisms of HA-induced vasorelaxation were not yet known. In the present study, the whole-cell patch-clamp technique was used to examine the effects of HA on ATP-sensitive K+ (K(ATP)) currents and membrane...

We propose a method for the generation of transverse valley currents, which is based on pure crossed Andreev reflection (pCAR) in superconducting hybrid junctions composed gapped $\ensuremath{\alpha}\ensuremath{-}{\mathcal{T}}_{3}$ lattices with ferromagnet-induced exchange interaction. The angle-resolved pCAR probability asymmetric given valley, resulting currents zero net charge. This assiste...

Uridine triphosphate (UTP) can be released from damaged cells to cause vasoconstriction. Although UTP is known to act through P2Y receptors and PLC activation in vascular smooth muscle, the role of PKC in generating the response is somewhat unclear. Here we have used Tat-linked membrane permeable peptide inhibitors of PKC to assess the general role of PKC and also of specific isoforms of PKC in...

Early afterdepolizations (EADs) induced by suppression of cardiac delayed rectifier IKr and/or IKs channels cause fatal ventricular tachyarrhythmias. In guinea-pig ventricular myocytes, partial block of one of the channels with complete block of the other reproducibly induced EADs. Complete block of both IKr and IKs channels depolarized the take-off potential and reduced the amplitude of EADs, ...

Glutamic acid activates ionotropic glutamate receptors that mediate excitatory transmission in the central nervous system. The introduction of a methyl group at position 4 of glutamic acid imparts selectivity for kainate receptors, relative to other (N-methyl-D-aspartate and alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid) ionotropic glutamate receptors. Among the stereoisomers of 4-me...

The O2 sensitivity of dissociated type I cells from rat carotid body increases with age until approximately 14-16 days. Hypoxia-induced depolarization appears to be mediated by an O2-sensitive K+ current, but other K+ currents may modulate depolarization. We hypothesized that membrane potential may be stabilized in newborn type I cells by human ether-a-go-go-related gene (HERG)-like K+ currents...

The ATP-sensitive potassium channel (K(ATP)) in mouse colonic smooth muscle cell is a complex containing a pore-forming subunit (Kir6.1) and a sulfonylurea receptor subunit (SUR2B). These channels contribute to the cellular excitability of smooth muscle cells and hence regulate the motility patterns in the colon. Whole-cell voltage-clamp techniques were used to study the alterations in K(ATP) c...

Characteristics of ionotropic gamma-aminobutyric acid (GABA) receptors at bullfrog cone terminals were studied by patch clamp techniques in isolated cell and retinal slice preparations. GABA-induced inward currents from isolated cones reversed in polarity at a potential, very close to the chloride equilibrium potential, and they were completely suppressed by picrotoxin. Unexpectedly, the GABA c...
