Backup-Protection Scheme for Multi-Terminal HVDC System Based on Wavelet-Packet-Energy Entropy

IEEE Access, 2019
DC fault protection is a major issue in multiterminal high-voltage DC current transmission systems. Most studies have focused on primary protection, which considers a different theory.

Power supply arm protection scheme of high-speed railway based on wide-area current differential

Railway Engineering Science, 2023
When fault occurs on cross-coupling autotransformer (AT) power supply traction network, the up-line and down-line feeder circuit breakers in the traction substation trip at the same time without selectivity, which leads to an extended power failure ...

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.

Multi-terminal flexible DC grid circuit breaker withstands multi-lightning strike analysis

Scientific Reports
Lightning represents the primary threat to power grids, with approximately 80% of natural occurrences being multi-lightning strikes, which have been extensively studied and confirmed to pose even more severe hazards.

Fault location in the observation matrix of collection lines for grid-connected wind power supported by grid-forming energy storage

International Journal of Electrical Power & Energy Systems
Aiming at the problem that the accuracy of fault location in the collection line supported by energy storage for wind power grid connection is easily affected by the number of measurement points and the access of power electronic equipment, a fault ...

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Active arc suppression method for voltage-current injection coordination in unbalanced distribution networks

International Journal of Electrical Power & Energy Systems
The challenge of extinguishing arc grounding faults persists as cable-based distribution networks become more prevalent. Current single injection arc extinction methods struggle to effectively mitigate arc grounding faults in unbalanced distribution ...

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Service restoration strategy for active distribution networks considering source-load uncertainty

International Journal of Electrical Power & Energy Systems
Active distribution networks (ADNs) incorporate numerous distributed generations (DGs) and energy storage systems. When sudden faults occur in the system, service restoration can be enhanced through microgrid formation and network reconfiguration ...

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...
