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.

Earth's Future, Volume 14, Issue 10, October 2026.Abstract This paper proposes an integrative conceptual framework for understanding systemic risk as emerging in highly interconnected socio‐ecological‐technical systems. Previous research has often examined hazard‐driven risk and vulnerability as separate analytical problems. We argue that systemic risk develops through their interaction within systems

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 5, October 2026.ABSTRACT In England's water sector, statutory Water Resources Management Plans (WRMPs) have become increasingly model‐led and document heavy. While this expansion is intended to strengthen evidence‐based decision‐making, transparency, and accountability, in practice it has contributed to a transparency failure: an evidence base that is formally public ...

Engineering Reports, Volume 8, Issue 9, September 2026.Taking the Ruyang Water Supply Project of Qianping Reservoir as the research object, a model was built with Bentley Hammer and valve closure schemes were optimized using the NSGA‑II algorithm. Results show that multistage closure is superior to single‑stage, and the optimized three‑stage scheme provides better water hammer protection, offering ...
