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.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Research on the improved hybrid DC circuit breaker with voltage-limiting and current-limiting capability

International Journal of Electrical Power & Energy Systems
The DC circuit breaker (DCCB) is a critical device that ensures the safe and reliable operation of the DC transmission system. As the level of DC voltage and transmission power increases, the flexible DC grid will need more and more opening capacity of ...

Opportunistic Transient-Fault Detection [PDF]

32nd International Symposium on Computer Architecture (ISCA'05), 2005
CMOS scaling increases susceptibility of microprocessors to transient faults. Most current proposals for transient-fault detection use full redundancy to achieve perfect coverage while incurring significant performance degradation. However, most commodity systems do not need or provide perfect coverage.

Fault section location of collector lines based on phase comparison of zero-sequence current using the Kaiser window

International Journal of Electrical Power & Energy Systems
To address the limitations of existing single-phase grounding fault location methods for collector lines in wind farms, especially their insufficient adaptability to multi-branch topologies, this paper proposes a fault section location method based on ...
