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.

The Governance of the European Digital Identity Framework Through the Lens of Institutional Mimesis
Regulation &Governance, EarlyView.ABSTRACT The European Commission's decision to expand its 2014 Regulation on electronic identification and trust services toward wallet‐based digital identities marked a significant shift in the governance of users' digital identities. The intersection between private digital services, public prerogatives, and individual self‐determination raises ...

When Regulation Travels: Distrust and Disrespect
Regulation &Governance, EarlyView.ABSTRACT Endeavoring to avoid the pitfalls of being too trusting of regulated entities' compliance claims, regulators sometimes create regulatory systems with elaborate requirements for verification. But as these accountability and verification regimes attempt to circumvent one set of problems, they may inadvertently create others.
