Optimized artificial neural network to improve the accuracy of estimated fault impedances and distances for underground distribution system.

PLoS ONE, 2020
This paper proposes an approach to accurately estimate the impedance value of a high impedance fault (HIF) and the distance from its fault location for a distribution system.

Iterative impedance analysis method on high integrated impedance network

Electronics Letters, 2010
An iterative type impedance analysis method for an impedance network is presented. The whole impedance network is divided into several sub-networks and each sub-network is analysed in a form of the linear voltage-current relation. The analysed voltage-current relation is iteratively applied to obtain the whole impedance. An illustrated example is given

On-Chip Matching Networks for Radio-Frequency Single-Electron-Transistors

, 2007
In this letter, we describe operation of a radio-frequency superconducting single electron transistor (RF-SSET) with an on-chip superconducting LC matching network consisting of a spiral inductor L and its capacitance to ground.

Failures in power-combining arrays [PDF]

, 1999
We derive a simple formula for the change in output when a device fails in a power-combining structure with identical matched devices. The loss is written in terms of the scattering coefficient of the failed device and reflection coefficient of an input ...

AAA+ protein unfoldases—the Moirai of the proteome

FEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Research on the modeling of the impedance match bond at station track circuit in Chinese high-speed railway

Advances in Mechanical Engineering, 2015
Frequency-shift keying audio jointless track circuit is used in high-speed railway in China. However, within the station, track circuit with mechanical insulation is applied. In complex circuit network of electrified railway station, impedance match bond

Dammarenediol II enhances etoposide‐induced apoptosis by targeting O‐GlcNAc transferase and Akt/GSK3β/mTOR signaling in liver cancer

Molecular Oncology, EarlyView.
Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...
