    Examining the Economic Costs of the 2003 Halloween Storm Effects on the North Hemisphere Aviation Using Flight Data in 2019 by Dabin Xue, Jian Yang, Zhizhao Liu, Shiwei Yu

    Published 2023-03-01
    “…We find that (a) as the high‐frequency communication blackouts may lead to polar flight rerouting and cancellations, possible daily economic costs could range from €0.21 million to €2.20 million per day; (b) during the satellite navigation failure period in the continental United States, as aircraft utilizes ground navigation aids as a backup, the increased flying time and disrupted descent approach operations may lead to additional cost of €2.43 million; (c) a surveillance failure can reduce airspace capacity and increase the workload of air traffic controllers, resulting in fatigue and perhaps risking flight safety; (d) to prevent massive cosmic radiation exposure, the economic costs of flight cancellations can be from €2.77 million to €48.97 million, depending on the cosmic radiation dose limits for a given plan. …”

    Ultrafine dendritic Cu particles for extremely fast pressure-assisted sintering under air and pore-free bond lines by Sang Hoon Jung, Jong-Hyun Lee

    Published 2025-03-01
    “…As a result, the bond line formed using the ultrafine Cu dendrite paste exhibited an exceptional shear strength of 42.8 MPa after only 10 s of bonding under 10 MPa compression at 300 °C in air. Furthermore, the formation of a near-full-density bond line microstructure without dendritic particle shapes or coarse voids was achieved. …”
