EXPRESS: Can location cues facilitate attentional suppression? [PDF]
The spatial cueing paradigm has illustrated that location cues result in attentional enhancement of target stimuli. However, evidence is mixed on whether proactive attentional suppression can be cued in a similar way. In this registered report, we used a

Adaptive transient overvoltage control strategy for wind farm based on data‐driven method
To achieve the transient overvoltage suppression of doubly fed induction generator (DFIG) terminals and the point of common coupling (PCC) in the wind farm (WF), an adaptive overvoltage control strategy based on data‐driven approach is proposed. Firstly,
