Mechanical performance degradation modelling and prognosis method of high‐voltage circuit breakers considering censored data

IET Science, Measurement & Technology
Due to the untimely deployment of sensors and the early retirement of high‐voltage circuit breakers, life‐cycle data is missing, leading to an inability to accurately predict the mechanical performance degradation trend.

The Monetary Policy–Commodities Nexus: A Survey

Journal of Economic Surveys, EarlyView.
ABSTRACT This survey synthesizes evidence on the bidirectional links between commodity markets and monetary policy. On the commodities‐to‐policy side, we review how shocks to energy, food, and metals pass through to inflation, inflation expectations, economic activity, and financial stability in state‐dependent ways that vary by shock type, exposure ...
