In Stage I (−11% < SOC ≤ 0%), the voltage dropped rapidly from 3.4 V to the minimum voltage of approximately −2.19 V, following a clear platform at approximately 1 V.
We investigated the minimum voltage required for tDCS using 1.5 and 2.5 mA.
The minimum voltage necessary for triggering Fowler Nordheim (FN) tunneling, under forward biasing, was ∼1.2 V and ∼3.4 V; respectively, below which only direct tunneling and thermionic emission events were evident.
In this study, the role of the metal/metal oxide or the lower metal oxide/higher metal oxide couple in determining the minimum voltage required for the evolution of oxygen is emphasized, together with other essential requirements such as electrical resistivity, electrode microstructure, corrosion resistance and catalytic properties.
The minimum voltage obtained for the system is better compared to the voltage obtained with DGs at unity power factor.
Therefore, the standard operating conditions are modified by reducing the Helium flow to 0.7 slm and the applied voltage to U rms =160 V, which is close to the minimum voltage necessary for ignition and low enough to keep the plasma operating in an α-mode.
A further improvement on the neuron detection method would be software that automatically vectorizes micrographs, produces the meshes in the vectorized images and solves the partial Laplace equations for the FOV to determine the minimum voltage to be used for extracellular stimulation.
The minimum voltage that is obtained for the system is better compared to the voltage obtained with DGs at unity power factor.
On the log scale, blue and red dotted lines correspond to the minimum voltage used to determine the MDA for the low-gain and high-gain configurations, respectively.
For example, the minimum voltage reached between spikes or the average voltage xx ms before each spontaneous spike (e.g., see: Koyama and Appel, 2006) can be provided as a pseudo-resting membrane potential.
