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.

Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures
High Voltage, EarlyView.ABSTRACT The pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the operational safety of trains.

Tubes or Ribbons? Comparing Texture‐space Visualization for Multivariate Line Data
Computer Graphics Forum, EarlyView.Abstract Multivariate line data is critical for analyzing flow fields, agent systems, and dynamic trajectories. Embedding secondary variables along spatial paths using surface‐based primitives such as ribbons and circular tubes introduces challenges related to perspective, scale, and distortion.

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.ABSTRACT Hybrid CFRP/GFRP laminates offer an attractive balance between mechanical performance, damage tolerance, and cost efficiency. However, fiber bridging during mode I delamination increases crack‐growth resistance while masking the intrinsic fatigue behavior of the material. This study applies a traction–separation‐based superposition approach to
