Ion currents through three types of rectifying nanoporous structures are studied and compared for the first time: conically shaped polymer nanopores, glass nanopipettes, and silicon nitride nanopores. Time signals of ion currents are analyzed by power spectrum. We focus on the low-frequency range where the power spectrum magnitude scales with frequency, f, as 1/f. Glass nanopipettes and polymer...
It has long been known with the Analytic Hierarchy Process (AHP) that addition or deletion of a copy of an existing alternative can cause the rank of other alternatives to reverse (Belton and Gear, 1983). Recently, Finan and Hurley (2002) discovered that removing a non-discriminating criterion from a multilevel AHP hierarchy causes the same phenomenon. This makes AHP appear deficient, since suc...
The Double Decker Turbine (DDT) is a recent design introduced for oscillating water column (OWC) devices. Its major contribution the combination of two typical solutions in just one prototype: self-rectifying performance, to deal with bidirectional flow, and twin-turbine concept, allowing use unidirectional turbines. This achieved by set concentric turbines, called external internal turbines (E...
Inwardly-rectifying potassium (Kir) channels contribute to maintenance of the resting membrane potential and regulation of electrical excitation in many cell types. Strongly rectifying Kir channels exhibit a very steep voltage dependence resulting in silencing of their activity at depolarized membrane voltages. The mechanism underlying this steep voltage dependence is blockade by endogenous pol...
