Impact of High-Frequency Voltage Distortion Emitted by Large Photovoltaic Power Plant on Medium Voltage Cable Systems

, 2021
Switching processes of voltage source converters can emit significant high-frequency distortions of frequencies between 5 to 20 kHz. Furthermore, the distortions can partly propagate from the place of their origin into a medium voltage system via ...

Liver organoids: modelling complexity in homeostasis and disease

FEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

FEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Toeplitz-MUSIC algorithm-based optimization scheme for UHV/EHV acoustic source localization

Discover Applied Sciences
To address the problems of weak anti-interference and large positioning error of the traditional 2D-MUSIC algorithm under low signal-to-noise ratio (SNR) in partial discharge (PD) localization of power transformer bushings, this paper proposes an ...

Distribution Optimization Method for Power Environment-Friendly Mixed Insulation Gas

Zhongguo dianli
The state-of-art cost of environmental-friendly SF6/CF4 mixed insulating gas of GIS equipment in the power system is relatively high. In order to ensure its insulation and arc extinguishing performance, SF6 gas is overfilled on site, which is not in line

Emerging experimental and computational methods for studying redox‐regulated structural transitions

FEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

FEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Neural Network-based CF4 and SF6/CF4 Detection in High Altitude and Extreme Cold Regions

Zhongguo dianli
In extreme cold regions, the need to carry multiple instruments to meet the demands for detecting varying concentration levels of CF4 gas within SF6 gas leads to inefficient field operations and high costs for instrument acquisition. To overcome this, an

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

FEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...
