Flexural performance of concrete‐filled steel tubular beams with wood chip aggregate

open access: yesStructural Concrete, EarlyView.
Abstract This study investigates the flexural performance of concrete‐filled steel tubular (CFST) beams with partial replacement of aggregates by wood chips (0%–25%) through experimental and numerical analysis. This study is novel in that it experimentally and numerically investigates the flexural behavior of CFST beams with partial replacement of ...

Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range

open access: yesWildlife Society Bulletin, EarlyView.
We studied the Kittlitz's murrelet, an ice‐associated seabird of conservation concern, at the northern edge of its range. Over a 2‐year period, we estimated nest density and success at 2 sites, captured and telemetered nesting murrelets, and tested the use of a thermal camera to improve nest detection.

Seismo‐ and Tsunami‐Traveling Ionospheric Disturbances of the 29 July 2025 M8.8 Kamchatka Earthquake Observed by CW‐HF Doppler Sounding Systems and Ionosondes in Taiwan and Japan

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Doppler frequency shifts (DFSs) recorded by continuous wave‐high frequency Doppler sounding systems and ionograms observed by five ionosondes in Taiwan and Japan are used to study three‐dimensionally seismo‐ and tsunami‐traveling ionospheric disturbances (STIDs and TTIDs) triggered by the 29 July 2025 Mw8.8 Kamchatka earthquake.

PancDS in Real‐World Practice: A Prospective Multicenter Validation of a Clinical Decision‐Support System Bridging Experience Gaps in Pancreatic Lesion Diagnosis

open access: yesAdvanced Science, Volume 13, Issue 45, 13 August 2026.
A biomimetic artificial intelligence system, PancDS, has been developed to distinguish pancreatic ductal adenocarcinoma from mass‐forming pancreatitis by adaptively integrating clinical data, radiomics, and deep learning features. Validated across multicenter, reader‐study, and prospective settings, PancDS improves diagnostic accuracy, particularly for

The role of precipitation and host assemblage composition in shaping bat–bat fly network structure

open access: yesEcosphere, Volume 17, Issue 8, August 2026.
Abstract Climatic seasonality plays an important role in shaping ecological interactions, including those between bats and their ectoparasitic bat flies. Although previous studies have acknowledged the influence of climate on the structure of bat–bat fly interaction networks, the existence of biogeographical patterns driven by climatic seasonality ...
