Demagnetization withstand capability enhancement of surface mounted PM machines using stator modularity [PDF]

open access: yes, 2017
The flux gaps in alternate stator teeth of the modular PM machines can have a significant impact on the total magnet flux density, and hence, the potential magnet reversible/irreversible demagnetization under flux weakening operations or short-circuit ...

A Scheme of DC-side Short-circuit Protection for Bi-directional Converterin Urban Rail Traction Power Supply System

open access: yesKongzhi Yu Xinxi Jishu, 2021
Using bi-directional converters for traction power supply in urban rail transit, traditional PWM rectifiers cannot meet the requirement of DC feeder protection for 27 kA short-circuit current with 120 ms continuous time.

19.2% Efficient InP Heterojunction Solar Cell with Electron-Selective TiO2 Contact. [PDF]

open access: yes, 2014
We demonstrate an InP heterojunction solar cell employing an ultrathin layer (∼10 nm) of amorphous TiO2 deposited at 120 °C by atomic layer deposition as the transparent electron-selective contact.

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Analysis of influencing factors of short-circuit spark discharge in electric potential capacitance circuit

open access: yesGong-kuang zidonghua, 2020
Most of existing models and methods for research of capacitive circuit spark discharge and high-power intrinsic safety power supply only consider discharge characteristics of energy storage elements during discharge process, and do not consider influence

Conserved structural motifs in PAS, LOV, and CRY proteins regulate circadian rhythms and are therapeutic targets

open access: yesFEBS Letters, EarlyView.
Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.
