Qualitative Evaluation of the Magnetocrystalline Anisotropy in Spinel Ferrite Nanoparticles Using Polarized Neutron Powder Diffraction

open access: yesSmall, EarlyView.
Polarized neutron powder diffraction is used to qualitatively probe the magnetocrystalline anisotropy of cobalt‐doped ferrite nanoparticles. The analysis of local magnetic susceptibility tensors and magnetization ellipsoids reveals how cobalt incorporation modifies both the magnitude and orientation of anisotropy, providing a new approach to compare ...

Energy Transfer in Nanodroplet‐Based Luminescent Solar Concentrators

open access: yesSmall, EarlyView.
We present novel luminescent solar concentrators (LSCs) featuring polymer composites with fluorescent dye‐doped oil nanodroplets. This liquid environment ensures high dye solubility and preserves fluorescence quantum yields, even at high local dye concentrations.

Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

open access: yesStructural Concrete, EarlyView.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...

Optimizing the Effectiveness of Captioned Viewing for Incidental Second Language Vocabulary Learning: The Effects of Repeated Viewing and Reading Fluency

open access: yesTESOL Quarterly, EarlyView.
Abstract This study examined the effects of repeated viewing and reading fluency on incidental second language vocabulary acquisition through captioned video exposure. A total of 149 Japanese EFL learners watched a short animation with or without captions, varying in the number of repetitions (once, twice, or three times).

Deep blueprint: A literature review and guide to automated image classification for ecologists

open access: yesJournal of Animal Ecology, EarlyView.
A practical, literature‐grounded review that gives ecologists a clear, modular workflow for deep learning image classification. With code, GUIs and a novel deep sea case study (automated deep sea biotope classification) it lowers technical barriers and provides a usable blueprint for accelerating, standardising, and scaling ecological image analysis ...

Social organization and habitat use shape the gut microbiome of a marine fish

open access: yesJournal of Animal Ecology, EarlyView.
This study provides the first evidence linking habitat use—and to a lesser extent social organization—to gut microbiome composition in a wild marine fish. The results indicate that local habitat conditions are the primary driver of microbial variation, while social effects are detectable but weak.

Agricultural Vulnerability Assessment: Climate and Non‐Climate Interactions in Crop Production Systems

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Recent climate phenomena show that Spain is one of the most vulnerable countries to climate change impacts, with varied regional effects from flash floods to drought. This study assesses the vulnerability of four major crops (cereal, rice, grape and olive) in Catalonia to climate change through a comprehensive vulnerability index incorporating
