Investigating the spatio–temporal characteristics of lower atmospheric ducts across the China seas by performing a long–term simulation using the WRF model [PDF]
Frontiers in Marine ScienceIn this work, a diagnostic scheme for lower atmospheric ducts was established based on the Weather Research and Forecasting (WRF) model. More specifically, a 10-year simulation test was conducted for the China seas to investigate the spatio-temporal ...

Utö Observatory for Analysing Atmospheric Ducting Events over Baltic Coastal and Marine Waters
Remote Sensing, 2023 Maritime safety relies on navigation, detection, and radio communication technologies that function through electromagnetic radiation. Propagation of electromagnetic radiation can be impacted by a disruptive phenomenon known as ducting.

A Biofabricated Human Acinus-on-a-Chip Unveils Mechanotransductive Drivers of Ventilator-Induced Lung Injury via Decoupling Volutrauma and Barotrauma. [PDF]
Adv Sci (Weinh)This bioinspired acinus‐on‐a‐chip recapitulates VILI pathology, revealing that volutrauma drives P53/NF‐κB pathways while barotrauma triggers mitochondrial‐Wnt dysregulation. A fibrotic transitional cell cluster was identified. Pharmacological interventions targeting these pathways significantly ameliorated injury, establishing a mechanobiological ...

Modeling the Development of Plasmasphere Ducts and Irregularities With SAMI3/WACCM‐X
Geophysical Research Letters, 2023 We show that atmospheric gravity waves can generate plasma ducts and irregularities in the plasmasphere using the coupled SAMI3/WACCM‐X model. We find the equatorial electron density is irregular as a function of longitude which is consistent with CRRES ...
