Evaluation Methodology, Numerical Verification and Retrofilling Procedure for Power Transformers to Ensure K‐Class Flame Retardancy and Environmentally Friendly

High Voltage, EarlyView.
ABSTRACT With increasing demands for fire safety and environmental friendliness, retrofilling transformers with alternative insulating liquids has become a growing trend. However, retrofilling power transformers remains uncertain, as more residual mineral oil compromises K‐class flame retardancy, and its impact on environmental performance has yet to ...

Correlated Transient Response of Buried Cables and Lightning Channel Radiation of Return Strokes of Five Rocket‐Triggered Lightning Strikes

High Voltage, EarlyView.
ABSTRACT Data from five rocket‐triggered lightning flashes are adopted to analyse the correlated transient response of buried cables and lightning channel radiations. These five flashes have the same termination point that is right above the buried cables and involve a total of 32 return strokes.

Study of Positive Corona Discharge of Needle Plate Electrodes in Airflow

High Voltage, EarlyView.
ABSTRACT For high‐speed moving objects such as aircraft and wind turbine blades, discharge occurs under strong airflow. Research on lightning attachment characteristics has been extensive, whereas the role of corona discharge in pre‐breakdown streamer development has received less attention.

Absolute scaling of small‐ and wide‐angle X‐ray scattering images recorded with short duration X‐ray pulses on a large area fiber‐taper X‐ray detector

Journal of Synchrotron Radiation, EarlyView.
An X‐ray scattering setup designed to capture small‐ and wide‐angle X‐ray scattering on a single, large area detector features a partially transmissive beamstop that facilitates non‐invasive recording of X‐ray beam position and intensity during acquisition of X‐ray scattering images.

e3SIM: Epidemiological‐ecological‐evolutionary simulation framework for genomic epidemiology

Methods in Ecology and Evolution, EarlyView.
Abstract Infectious disease dynamics result from the complex interplay of epidemiological, ecological and evolutionary (epi‐eco‐evo) processes. Accurately modelling these coupled processes is crucial for understanding pathogen spread and informing public health strategies.
