The wildlife strikes back: determining the secondary strike risk associated with a mammal–aircraft collision

open access: yesThe Journal of Wildlife Management, Volume 89, Issue 7, September 2025.
Wildlife‐aircraft collisions are a growing concern. This study at Dublin Airport investigated the secondary strike risk posed by scavengers using simulated hare‐strike events. Results showed that birds, especially hooded crows, detected carcasses faster than mammals, supporting the effectiveness of current rapid clean‐up protocols in minimizing ...

Impact of Wind‐Wave Coupling on Turbulence and Air‐Sea Fluxes: Insights From Direct Numerical Simulations

open access: yesGeophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract Accurate prediction of air‐sea fluxes hinges on a deep understanding of wind‐wave interactions, yet feedback mechanisms involving surface waves and wind are not fully understood. This paper investigates the effect of two‐way coupling between wind and waves on wind turbulence through direct numerical simulation of air‐water two‐phase flows ...

Air-Side Nusselt Numbers and Friction Factor’s Individual Correlations of Finned Heat Exchangers

open access: yesEnergies, 2022
Currently, when designing finned heat exchangers (FHE), the average value of the entire heat transfer coefficient (HTC) is considered. However, each row of the heat exchanger (HEX) has different hydraulic-thermal characteristics.

Wave Glider‐Based Measurements and Corrections of Near‐Surface pCO2 Gradients in the Coastal Ocean

open access: yesGlobal Biogeochemical Cycles, Volume 39, Issue 7, July 2025.
Abstract Carbonate system dynamics are highly variable in coastal and shelf regions, and poor spatiotemporal measurement resolution leads to inadequate constraints for global carbon sequestration estimates. Additionally, conventional pCO2 measurement‐based flux calculations require an assumption of homogeneity in near‐surface waters, excluding effects ...

Strategies for Controlling Emission Anisotropy in Lead Halide Perovskite Emitters for LED Outcoupling Enhancement

open access: yesAdvanced Materials, Volume 37, Issue 25, June 26, 2025.
The rise of lead halide perovskite semiconductors has enabled high‐performance LEDs with internal quantum efficiencies approaching 100%. In order to further enhance the external quantum efficiencies limited by light outcoupling effects, in this account, the strategies for reducing energy dissipation through the substrate, waveguide, and evanescent ...
