Complex oscillatory redox dynamics with signaling potential at the edge between normal and pathological mitochondrial function
(Frontiers, 2014-06)
The time-keeping properties bestowed by oscillatory behavior on functional rhythms represent an evolutionarily conserved trait in living systems. Mitochondrial networks function as timekeepers maximizing energetic output ...
Membrane potential resonance in non-oscillatory neurons interacts with synaptic connectivity to produce network oscillations
(Springer, 2019-03-20)
Several neuron types have been shown to exhibit (subthreshold) membrane potential resonance (MPR), defined as the occurrence of a peak in their voltage amplitude response to oscillatory input currents at a preferred ...
Oscillatory dynamics of a superconductor vortex lattice in high amplitude ac magnetic fields
(American Physical Society, 2005-12)
We study by ac susceptibility measurements the evolution of the solid vortex lattice mobility under oscillating forces. It has already been shown that in YBCO single crystals, below the melting transition, a temporarily ...
Muscarinic modulation of high frequency oscillations in pedunculopontine neurons
(Frontiers Research Foundation, 2013-11)
We previously reported that persistent application of the non-specific cholinergic agonist carbachol (CAR) increased the frequency of calcium channel-mediated oscillatory activity in pedunculopontine nucleus (PPN) neurons, ...
Self-sustained oscillations in the potential of a CO-poisoned PEM fuel cell: A model based on physical principles
(Elsevier Science SA, 2021-01-01)
A dynamic 1-D model for the simulation of the oscillatory behavior in the anode potential of a PEM fuel cell under constant current conditions and the presence of CO impurities in the H2 inlet is presented. The model is ...
Wavelet analysis of corneal endothelial electrical potential difference reveals cyclic operation of the secretory mechanism
(American Physical Society, 2011-09)
The corneal endothelium is a fluid-transporting epithelium. As other similar tissues, it displays an electrical potential of ∼1 mV (aqueous side negative) across the entire layer [transendothelial potential difference ...
Anisotropic k-essence cosmologies
(American Physical Society, 2006-03)
We investigate a Bianchi type-I cosmology with k-essence and find the set of models which dissipate the initial anisotropy. There are cosmological models with extended tachyon fields and k-essence having a constant barotropic ...
Seismic wave attenuation and dispersion due to wave-induced fluid flow in rocks with strong permeability fluctuations
(Acoustical Society of America Institute of Physics, 2013-06)
Oscillatory fluid movements in heterogeneous porous rocks induced by seismic waves cause dissipation of wave field energy. The resulting seismic signature depends not only on the rock compressibility distribution, but also ...
Subthreshold membrane potential oscillations in inferior olive neurons are dynamically regulated by P/Q- and T-type calcium channels: a study in mutant mice
(Wiley, 2010-08)
The role of P/Q- and T-type calcium channels in the rhythmic oscillatory behaviour of inferior olive (IO) neurons was investigated in mutant mice. Mice lacking either the CaV2.1 gene of the pore-forming α1A subunit for ...
Simplified Approach to Work Function Modulation in Polyelectrolyte Multilayers
(American Chemical Society, 2017-03)
The layer-by-layer (LbL) method is based on sequential deposition of polycations and polyanions. Many of the properties of polyelectrolyte thin films deposited via this method depend on the nature of the topmost layer. ...
