Anomalies and Recovery of Evaporation Ducts Induced by Typhoons in the Northwest Pacific

open access: yesGeophysical 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.

Metasurface‐Enabled Active‐Like Passive Radar

open access: yesAdvanced Science, Volume 13, Issue 44, 7 August 2026.
A programmable space‐time‐coding metasurface embeds distinct spatiotemporal tags into ambient wireless signals, allowing passive radar to operate in an active‐like manner. By enabling code‐correlated reconstruction under interference, the approach supports robust real‐time UAV tracking in complex environments and points to intelligent, low‐power ...

Self‐Similar Blowup for the Cubic Schrödinger Equation

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1831-1918, August 2026.
ABSTRACT We give a rigorous proof for the existence of a finite‐energy, self‐similar solution to the focusing cubic Schrödinger equation in three spatial dimensions. The proof is computer‐assisted and relies on a fixed point argument that shows the existence of a solution in the vicinity of a numerically constructed approximation.

Chiroptera Personality—A Guide for Assessing Personality Variation in Bats: Ecological, Methodological and Statistical Considerations

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
This paper addresses the underrepresentation of bats in animal personality research despite their ecological importance, offering a structured guide for studying consistent individual behavioural differences in this taxon. We outline key experimental, fieldwork and annotation considerations specific to bats' unique life histories, alongside a five‐step
