Secure Communication in Millimeter Wave Relaying Networks
IEEE Access, 2019 The use of relay can expand the coverage of millimeter-wave (mmWave) signals, whereas it may increase the risk of information leakage due to the additional link from source to relay.

Optimal Number of Transmit Antennas for Secrecy Enhancement in Massive MIMOME Channels
, 2017 This paper studies the impact of transmit antenna selection on the secrecy performance of massive MIMO wiretap channels. We consider a scenario in which a multi-antenna transmitter selects a subset of transmit antennas with the strongest channel gains ...

Journal of Flood Risk Management, Volume 19, Issue 1, March 2026.ABSTRACT The increasing severity of flood events poses growing risks to critical infrastructures (CI), with failures often triggering cascading effects across sectors. Despite this, flood risk management (FRM) frequently overlooks service disruptions of CI and systemic interdependencies between infrastructure sectors because of its place‐based approach.

Journal of Research on Adolescence, Volume 36, Issue 1, March 2026.Abstract Adolescence is a critical period for developing coping capacities, yet global crises like the COVID‐19 pandemic and war displacement impose unprecedented stressors that can overwhelm existing resources. This study qualitatively explored and compared how adolescents in Germany (N = 20 experiencing pandemic lockdown, aged 11–16; N = 25 Ukrainian

Extreme‐weather risk and the cross‐section of stock returns
Journal of Risk and Insurance, Volume 93, Issue 1, Page 163-198, March 2026.Abstract We document an extreme‐weather risk premium in the cross‐section of stock returns. Between 1995 and 2019, stocks of domestic U.S. firms with the most negative sensitivity to aggregate storm losses earned an annual excess‐return spread of more than 6 percentage points relative to those with the most positive sensitivity, a difference not ...

The Canadian Journal of Chemical Engineering, Volume 104, Issue 2, Page 935-952, February 2026.Abstract Remaining useful life (RUL) analysis of equipment prevents failures and assists in maintenance to address impending failures. To achieve this, the advancement of degradation can be measured through a determinant variable. This work presents a new methodology for estimating the number of remaining cycles (NRC), or RUL, of equipment in cyclic ...

Beyond Deaths and Dollars: Modeling Requirements to Support Equity‐Focused Disaster Risk Management
Earthquake Spectra, Volume 42, Issue 1, February 2026.The disaster risk modeling framework has long focused on quantifiable impact metrics to assess a hazard's potential direct effects, such as fatalities (deaths) and economic losses (dollars). Over time, as the framework has expanded to inform both public and private applications, additional impact metrics that more directly consider the societal roots ...

Orbital Angular Momentum: From State Disentanglement Towards the Secrecy Outage Probability
, 2022 How are we able to fix it so as to theoretically go over it, if the optimality and efficiency of the orbital angular momentum (OAM) multiplexing technique in a multi-input multi-output (MIMO) system fails in practice -- something that technically causes a considerable reduction in the maximum achievable value of the transceiver's degree-of-freedom?
