Leading the Loop: Anchor‐Led Orchestration in Nascent Circular Ecosystems—A Qualitative Case Study

Business Strategy and the Environment, EarlyView.
ABSTRACT The transition towards a circular economy necessitates coordinated, systemic change across value chains. Yet the role of anchor firms in initiating and orchestrating nascent circular ecosystems remains underexplored. Using an inductive, qualitative single‐case design, we analyse a German mid‐sized entrepreneurial firm, drawing on 21 interviews

Artificial Intelligence–Driven and Digital Practices for Circular Business and Finance: Insights for Advancing Hubs for Circularity

Business Strategy and the Environment, EarlyView.
ABSTRACT The emerging concept of Hubs for Circularity (H4Cs) presents an opportunity to create collaborative, self‐sustaining regional industrial ecosystems that drive circular economy transitions at scale. However, the operationalisation of H4Cs faces financial, organisational and data‐driven challenges.

Analysis of a Pareto Mixture Distribution for Maritime Surveillance Radar

Journal of Electrical and Computer Engineering, 2012
The Pareto distribution has been shown to be an excellent model for X-band high-resolution maritime surveillance radar clutter returns. Given the success of mixture distributions in radar, it is thus of interest to consider the effect of Pareto mixture ...

Circular Innovations in Complex Systems: A Blueprint of Four Design Archetypes

Business Strategy and the Environment, EarlyView.
ABSTRACT Circular innovations (CI), defined as the redesign of products, services or practices to minimise waste, reduce resource use and regenerate natural systems, are essential for advancing the circular economy. Despite growing recognition, their deployment in systems of linked parts with unpredictable interactions (complex systems) remains limited

Status epilepticus: Updates on mechanisms and treatments

Epilepsia Open, EarlyView.
Abstract Status epilepticus (SE) consists of prolonged, self‐sustaining seizures and is a common neurological emergency that causes respiratory compromise and neuronal injury. Without prompt treatment, the seizures can become resistant to benzodiazepines, leading to the progressive evolution of established, refractory, and super‐refractory SE.
