When Current Does Not Follow Bonds: Current Density in Saturated Molecules [PDF]
The Journal of Physical Chemistry C, 2019 The tools commonly used to understand structure-property relationships in molecular conductance, inter-atomic currents and conductance eigenchannels, generally give us a sense of familiarity, with the chemical bonding framework and molecular orbitals reflected in the current.

Digital signal propagation delay in a nano-circuit containing reactive and resistive elements [PDF]
, 2011 The transient switching delay in a micro/nano-scale circuit containing resistive and reactive elements are sternly affected by the surge in the resistance arising from sub-linear current-voltage (I-V) characteristics limited by the velocity and current ...

On current-density algebras, gradient terms and saturation
Communications in Mathematical Physics, 1968 The equal time limit of commutator matrix elements of conserved currents is rigorously calculated by means of structures which follow from general principles of relativistic quantum field theory and current conservation. We prove: (a) In general derivatives of δ-functions occur (gradient terms).

Current Transformer Saturation Detection Method Based on Artificial Neural Network
Известия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2023 When current transformer is saturated, mainly due to the presence of an exponentially decaying DC component in the fault current, its secondary current has a distinctive distorted waveform which significantly differs from its primary (true) waveform.

Lee Waves Break Eddy Saturation of the Antarctic Circumpolar Current
Geophysical Research Letters, 2023 Eddy‐resolving ocean models suggest that the transport of the Antarctic Circumpolar Current (ACC) may be insensitive to increasing wind. This insensitivity is due to eddies that flatten the isopycnals and compensate for their wind‐driven steepening ...
