Mathematical solutions and numerical illustrations are presented for the steady-state distribution of membrane potential in an extensively branched neuron model, when steady electric current is injected into only one dendritic branch. Explicit expressions are obtained for input resistance at the branch input site and for voltage attenuation from the input site to the soma; expressions for AC st...

The ground-breaking results of Wang et al. have attracted a lot of attention to the collision resistance of hash functions. In their articles, Wang et al. give input differences, differential paths and the corresponding conditions that allow to find collisions with a high probability. However, Wang et al. do not explain how these paths were found. The common assumption is that they were found b...

Whole cell voltage clamp studies were performed upon isolated and small groups of supporting cells from the guinea pig organ of Corti in order to evaluate junctional and non-junctional membrane characteristics. Single Hensen cells have an average input resistance and capacitance of 1.03 G omega and 24.9 pF, respectively. I-V functions indicate an outward K+ rectification, which is blocked by ex...

This paper introduces a Transimpedance Amplifier (TIA) design capable of producing an incremental input resistance in the ohmic range, for signals microampere such as are encountered instrumentation electrochemical ampero-metric sensors, optical-sensing and current-mode circuits. low input-resistance is achieved using stage incorporating negative feedback. In Cadence simulation exemplary 180 nm...
