Accurate MRAS Embedded Minimum Copper-Loss Based Controller for WRIG Coupled With Variable Speed Wind Turbine

IEEE Access, 2023
Sensorless control of the wound rotor induction generator (WRIG) using the model reference adaptive system (MRAS) technique is an attractive option in wind energy generation schemes. However, the accuracy of MRAS under variable wind speed situations is a

Rotor position estimation of wound‐rotor synchronous starter/generator

The Journal of Engineering, 2018
This study proposes a novel rotor position estimation method for wound‐rotor synchronous starter/generator (WSSG). At starting stage, WSSG needs a resolver to obtain main generator (MG)'s rotor position. However, the use of resolver increases starting system's complexity, volume, weight and cost. In order to solve this problem, a new kind of MG's rotor

Molecular Engineering Boosts Photon‐Activated Immunotherapy for Prostate Cancer Through Concurrent Pyroptosis and cGAS‐STING Pathway Activation

Angewandte Chemie, EarlyView.
The engineered DTSe‐based photosensitizer, DZTSe, emerges as an avant‐garde molecular entity, which can distribute to both the endoplasmic reticulum and mitochondria to concurrently trigger pyroptosis and activate the cGAS‐STING pathway. This dual‐action strategy effectively reprograms the tumor microenvironment, enabling potent eradication of primary ...

Negotiating in a Foreign Land: Understanding the Curious Interactions Between Intracellular Mitochondria and Internalized Nanoparticles

Advanced Materials Interfaces, EarlyView.
Therapeutic nano‐drug delivery systems interact with cellular mitochondria in a multitude of ways. While the complexity of such interactions disrupts the mitochondrial electron transport chain and increases reactive oxygen species production, thereby contributing to nanoparticle toxicity, they also present unique theranostic opportunities in diseases ...

IL‐7R‐Enriched Extracellular Vesicles From the Thymus Drive Colitis via Promoting Neutrophil Extracellular Trap Formation

Advanced Science, EarlyView.
Inflammatory bowel disease (IBD) pathogenesis remains unclear. This study reveals that thymus‐originated IL‐7R‐enriched extracellular vesicles exacerbate colitis by promoting neutrophil extracellular traps via a thymus‐gut axis, uncovering an inter‐organ communication mechanism in inflammatory bowel disease pathogenesis.
