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

Kongzhi 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.

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Noise margin and short-circuit current in FGMOS logics [PDF]

, 2011
Even when floating-gate logics are very-low-voltage circuits, as power supply is reduced, large fan-in FGMOS gates are prone to fail. Thus, determining the negative impact of noise margin and short-circuit current in this type of circuits is crucial to ...

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

FEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.
