Distribution network planning based on double deep Q‐network with self‐adjusting parameters
Energy Conversion and Economics, Volume 7, Issue 2, Page 105-126, April 2026.Abstract To address the challenge of low adaptability in distribution network planning caused by significant regional differences in electricity consumption, this paper proposes a distribution network planning method based on a self‐adjusting parameter double deep Q‐network (SAP‐DDQN).

Decision Sciences, Volume 57, Issue 2, Page 133-152, April 2026.Abstract We study a supply chain subject to supply disruptions, where the supplier can exert costly effort to mitigate the impact of disruptions and improve reliability. The supplier's current reliability level and the cost of improving reliability can each be high or low and are privately known only to the supplier.

Physical Layer Security Using Two-Path Successive Relaying
Sensors, 2016 Relaying is one of the useful techniques to enhance wireless physical-layer security. Existing literature shows that employing full-duplex relay instead of conventional half-duplex relay improves secrecy capacity and secrecy outage probability, but this ...

Best Before? Expiring Central Bank Digital Currency and Loss Recovery
Journal of Money, Credit and Banking, Volume 58, Issue 3, Page 787-819, April 2026.Abstract Physical cash enables payments in the absence of electricity or network coverage. Such offline payment functionality promotes the operational resilience and, particularly in developing countries, the accessibility of payments. Central banks are exploring issuing digital cash substitutes with similar offline payment functionality.
