Relaying Communications in Energy Scavenging Cognitive Networks: Secrecy Outage Probability Analysis [PDF]

Wireless Communications and Mobile Computing, 2019
This paper exploits a self-powered secondary relay to not only maintain but also secure communications between a secondary source and a secondary destination in cognitive radio networks when source-destination channel is unavailable. The relay scavenges energy from radio frequency (RF) signals of the primary transmitter and the secondary source and ...

Hurricane‐induced risk contagion in commercial real estate: Evidence from Hurricane Sandy

Real Estate Economics, EarlyView.
Abstract This study examines how hurricane‐induced destruction affects the prices of nearby undamaged commercial real estate properties, using Hurricane Sandy as a natural experiment. Using Real Capital Analytics transaction records spatially merged with Federal Emergency Management Agency building‐level damage data, we empirically employ a difference ...

Economic activity during extreme events

Canadian Journal of Economics/Revue canadienne d'économique, EarlyView.
Abstract Although extreme weather events, natural disasters or infrastructure failures potentially have important economic effects, quantifying these effects over small areas and fine time intervals has been difficult because of the fairly coarse scales available in most data sources. This paper surveys the use of relatively new and finely grained data

Joint Relay and Jammer Selection Improves the Physical Layer Security in the Face of CSI Feedback Delays

, 2015
We enhance the physical-layer security (PLS) of amplify-and-forward relaying networks with the aid of joint relay and jammer selection (JRJS), despite the deliterious effect of channel state information (CSI) feedback delays.

Incentive contract design for supplier reliability: The role of asymmetric information on reliability level and improvement costs

Decision Sciences, EarlyView.
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.

Best Before? Expiring Central Bank Digital Currency and Loss Recovery

Journal of Money, Credit and Banking, EarlyView.
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.

Blame and Cost: Understanding Responsibility Attribution and Financial Risk in AI Usage

Journal of Contingencies and Crisis Management, Volume 34, Issue 1, March 2026.
ABSTRACT This study examines public perceptions of responsibility and potential damage associated with AI usage across various scenarios, and estimates the financial impact on firms. The survey‐based analyses of AI failures evaluating hypothetical risk scenarios and their economic consequences reveal that sociodemographic determinants shape the ...
