Potential capacities of quantum channels [PDF]
IEEE Transactions on Information Theory, 2016 We introduce potential capacities of quantum channels in an operational way and provide upper bounds for these quantities, which quantify the ultimate limit of usefulness of a channel for a given task in the best possible context.

An embedding potential definition of channel functions [PDF]
Physical Review B, 2004 We show that the imaginary part of the embedding potential, a generalised logarithmic derivative, defined over the interface between an electrical lead and some conductor, has orthogonal eigenfunctions which define conduction channels into and out of the

Sodium channels amplify spine potentials [PDF]
Proceedings of the National Academy of Sciences, 2007 Dendritic spines mediate most excitatory synapses in the brain. Past theoretical work and recent experimental evidence have suggested that spines could contain sodium channels. We tested this by measuring the effect of the sodium channel blocker tetrodotoxin (TTX) on depolarizations generated by two-photon uncaging of glutamate on spines from mouse ...

Transient Receptor Potential (TRP) Channels [PDF]
, 2018 Transient Receptor Potential (TRP) channels are evolutionarily conserved integral membrane proteins. The mammalian TRP superfamily of ion channels consists of 28 cation permeable channels that are grouped into six subfamilies based on sequence homology (Fig. 6.1).

Potentiated L-type Ca2+ Channels Rectify [PDF]
The Journal of General Physiology, 2003 Strong depolarization and dihydropyridine agonists potentiate inward currents through native L-type Ca2+ channels, but the effect on outward currents is less clear due to the small size of these currents. Here, we examined potentiation of wild-type α1C and two constructs bearing mutations in conserved glutamates in the pore regions of repeats II and IV

Eag1 Channels as Potential Cancer Biomarkers [PDF]
Sensors, 2012 Cancer is a leading cause of death worldwide. New early tumor markers are needed to treat the disease at curable stages. In addition, new therapeutic targets are required to treat patients not responding to available treatments. Ion channels play major roles in health and disease, including cancer.

Oncogenic potential of EAG K+ channels [PDF]
The EMBO Journal, 1999 We have investigated the possible implication of the cell cycle-regulated K(+) channel ether à go-go (EAG) in cell proliferation and transformation. We show that transfection of EAG into mammalian cells confers a transformed phenotype. In addition, human EAG mRNA is detected in several somatic cancer cell lines, despite being preferentially expressed ...

Transient receptor potential channels meet phosphoinositides [PDF]
The EMBO Journal, 2008 Transient receptor potential (TRP) cation channels are unique cellular sensors that are involved in multiple cellular functions, ranging from transduction of sensory signals to the regulation of Ca(2+) and Mg(2+) homoeostasis. Malfunctioning of TRP channels is now recognized as the cause of several hereditary and acquired human diseases. At the time of

Feshbach resonances with large background scattering length: interplay with open-channel resonances [PDF]
, 2004 Feshbach resonances are commonly described by a single-resonance Feshbach model, and open-channel resonances are not taken into account explicitly. However, an open-channel resonance near threshold limits the range of validity of this model.

On the Security of Ultrasound as Out-of-band Channel [PDF]
, 2007 Ultrasound has been proposed as out-of-band channel for authentication of peer devices in wireless ad hoc networks. Ultrasound can implicitly contribute to secure communication based on inherent limitations in signal propagation, and can additionally be ...
