A current deviation control parameter tuning method to suppress subsequent commutation failure

If a subsequent commutation failure occurs in the line commutated converter-based high voltage direct current (LCC-HVDC) transmission system, it will have a seriously negative impact on the safe and stable operation of the AC-DC hybrid power grid. Aiming

Straddling “The Gulf Between Medicine and Law”: Medico‐legal addiction and Japanese psychiatry

Medical Anthropology Quarterly, EarlyView.
Abstract Increasing punitive drug regulations in Japan amplify longstanding tensions within psychiatric practice, pushing psychiatrists to balance clinical obligations with complex socio‐legal demands. This article analyzes how psychiatrists specializing in illicit substance use disorders to navigate escalating criminalization by developing diagnostic ...

Distinct Surcharge Effects in Taxi Markets: Evidence From New York City Yellow Cabs

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT This paper examines how alternative surcharge designs affect market outcomes in the New York City (NYC) Yellow Cab system. We study two distinct policies: a congestion surcharge that raises passenger fares without directly compensating drivers, and a rush‐hour surcharge that provides time‐based incentives to drivers during periods of high ...

Avoidance Behaviours and Constraints: Temperature and Labour Supply in the United Kingdom

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT Temperature can play an important role in time allocation decisions like labour supply as workers seek to avoid harmful exposure or enjoy higher utility from leisure. Using time use survey data, we estimate the effect of temperature on labour supply in the UK.
