An Optimal Frequency Control Method of Asynchronous Power Grid Considering Multi-HVDC Emergency Power Support

IEEE Access, 2022
Emergency DC power support has become an effective frequency stability control approach. For the asynchronous power grid with multi-HVDC links, this paper proposes an optimal control based on wide-area measurements (WAMS). The prominent advantage of this

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Research on Emergency Frequency Control in AC/DC Hybrid Power Systems

IEEE Access
Harmonic state estimation is an important tool for power quality management. Current methods mostly rely on idealized real-time and synchronized harmonic data, without considering practical challenges such as non-real-time and asynchronous data, which ...

On power system frequency control in emergency conditions\ud [PDF]

, 2008
Frequency regulation in off-normal conditions has been an important problem in electric power system design/operation and is becoming much more significant today due to the increasing size, changing structure and complexity of interconnected power ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

The Emergency Department Crash Cart: A systematic review and suggested contents [PDF]

, 2018
BACKGROUND: As the field of Emergency Medicine grows worldwide, the importance of an Emergency Department Crash Cart (EDCC) has long been recognized. Yet, there is paucity of relevant peer-reviewed literature specifi cally discussing EDCCs or proposing ...

Translophagy—A potential link between autophagy impairment and translational errors

FEBS Letters, EarlyView.
Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

FEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...
