Anomalies and Recovery of Evaporation Ducts Induced by Typhoons in the Northwest Pacific
Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract Despite widespread attention on tropical cyclone (TC)‐induced cold wakes, the dynamic recovery of evaporation duct height (EDH) post‐typhoon remains unclear. Using ERA5 data from 338 Northwestern Pacific TCs (2003–2023), we quantify the spatiotemporal evolution of EDH after TC passage.

Analysis of a Pareto Mixture Distribution for Maritime Surveillance Radar
Journal of Electrical and Computer Engineering, 2012 The Pareto distribution has been shown to be an excellent model for X-band high-resolution maritime surveillance radar clutter returns. Given the success of mixture distributions in radar, it is thus of interest to consider the effect of Pareto mixture ...

Interpreting How Neural Networks Infer Scatterer Geometry from Echolocation Echoes
Advanced Intelligent Systems, Volume 8, Issue 8, August 2026.Neural networks enable echolocation‐based shape classification but remain difficult to interpret due to their black‐box nature. This work presents a feature‐importance metric to uncover the echo regions driving decisions in shape‐specialized networks.
