Electron injection in a nanotube with leads: finite frequency noise-correlations and anomalous charges

, 2004
The non-equilibrium transport properties of a carbon nanotube which is connected to Fermi liquid leads, where electrons are injected in the bulk, are computed.

Power Flow-Based Estimation of Short-Circuit Currents From Inverter-Based Resources

IEEE Open Access Journal of Power and Energy
The generator side of inverter-based resources (IBRs) interfaced with back-to-back converters is electrically decoupled from the grid. During electrical faults, grid-following IBRs behave as voltage-dependent current sources due to grid code requirements

Down-Regulation of Na+/K+ ATPase Activity by Human Parvovirus B19 Capsid Protein VP1

Cellular Physiology and Biochemistry, 2013
Background/Aims: Human parvovirus B19 (B19V) may cause inflammatory cardiomyopathy (iCMP) which is accompanied by endothelial dysfunction. The B19V capsid protein VP1 contains a lysophosphatidylcholine producing phospholipase A2 (PLA) sequence ...

Fast Sequence Component Analysis for Attack Detection in Synchrophasor Networks [PDF]

, 2015
Modern power systems have begun integrating synchrophasor technologies into part of daily operations. Given the amount of solutions offered and the maturity rate of application development it is not a matter of "if" but a matter of "when" in regards to ...

Magnetization dependent current rectification in (Ga,Mn)As magnetic tunnel junctions

, 2011
We have found that the current rectification effect in triple layer (double barrier) (Ga,Mn)As magnetic tunnel junctions strongly depends on the magnetization alignment.

Hot-spot formation in stacks of intrinsic Josephson junctions in Bi2Sr2CaCu2O8

, 2012
We have studied experimentally and numerically temperature profiles and the formation of hot spots in intrinsic Josephson junction stacks in Bi2Sr2CaCu2O8 (BSCCO). The superconducting stacks are biased in a state where all junctions are resistive.

Design of a High-Performance High-Pass Generalized Integrator Based Single-Phase PLL

, 2016
Grid-interactive power converters are normally synchronized to the grid using phase-locked loops (PLLs). The performance of the PLLs is affected by the non-ideal conditions in the sensed grid voltage such as harmonics, frequency deviations and dc offsets

Optical computing by injection-locked lasers

, 2017
A programmable optical computer has remained an elusive concept. To construct a practical computing primitive equivalent to an electronic Boolean logic, one should find a nonlinear phenomenon that overcomes weaknesses present in many optical processing ...
