The genetic architecture underlying the evolution of a rare piscivorous life history form in brown trout after secondary contact and strong introgression [PDF]

open access: yes, 2018
Identifying the genetic basis underlying phenotypic divergence and reproductive isolation is a longstanding problem in evolutionary biology. Genetic signals of adaptation and reproductive isolation are often confounded by a wide range of factors, such as

Vernacularizing the Best Interests of the Child: Comparative Insights From Three Legal Systems

open access: yesJournal of Family Theory &Review, EarlyView.
ABSTRACT The study investigates how the Best Interests of the Child principle in the UN Children's Rights Convention (Article 3) has been adapted in custody disputes in Egypt, Sweden, and Uzbekistan. Although the Convention on the Rights of the Child offers a common normative benchmark, divergent legal cultures shape its domestic meaning: Egypt is ...

Vortex Fluctuations in High-Tc Films: Flux Noise Spectrum and Complex Impedance

open access: yes, 1999
The flux noise spectrum and complex impedance for a 500 {\AA} thick YBCO film are measured and compared with predictions for two dimensional vortex fluctuations.

Plastid and nuclear phylogenomics of Cyphostemma (Vitaceae) provide new insights into genome size evolution across sub‐Saharan Africa

open access: yesJournal of Integrative Plant Biology, EarlyView.
Some African Cyphostemma species evolved much larger genomes as they adapted to dry, rocky habitats. These expansions are linked to succulent traits and specialization on nutrient‐rich limestone outcrops. The findings show how climate‐driven aridification shaped plant evolution and highlight broader genome‐environment patterns across flowering plants ...

Generation of surface plasmons by electron beam excitation

open access: yes, 2007
We report on the first demonstration of excitation of propagating surface plasmon polaritons (SPPs) by injection of a beam of free electrons on an unstructured metal interface, providing a highly localized and intense source of plasmon waves.

Values of Individuals With Rare Genetic Neurodevelopmental Disorders and Their Family/Caregivers in Healthcare: A Scoping Review to Inform Guideline Development

open access: yesJournal of Intellectual Disability Research, EarlyView.
ABSTRACT Background Healthcare decision‐making for individuals with rare genetic neurodevelopmental disorders (RGNDs) associated with intellectual disabilities (ID) can be complex due to the intersection of lifelong care needs, limited medical expertise and communication barriers.

Polar Lipid and Fatty Acid Profiles of Oat Groats Substantially Influenced by Field Management: A Comparison of Cultivars, Sowing Times and Fertilizer Composition

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT The polar lipids in oat grains are crucial due to their biological functions, nutritional quality, potential use in food flavour and processing, the protection they provide against biotic and abiotic stresses, and their ability to act as cellular signalling molecules.

Fundamental bounds on transmission through periodically perforated metal screens with experimental validation

open access: yes, 2019
This paper presents a study of transmission through arrays of periodic sub-wavelength apertures. Fundamental limitations for this phenomenon are formulated as a sum rule, relating the transmission coefficient over a bandwidth to the static polarizability.

Methyl Jasmonate Seed Priming Mitigates the Defence‐Growth Trade‐Off and Tailors Plant Response to Specific Pests

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Seed defence priming is emerging as a novel, cost‐efficient and environmentally safe tool for pest management. It has been proposed as a means to uncouple the defence‐growth trade‐off in plants by enhancing defence responses with minimal fitness costs, but the mechanisms underlying this role remain elusive.

Contemporary disasters may not kill more women than men: an empirical inquiry into sex‐differentiated fatalities in the twenty‐first century

open access: yesDisasters, Volume 50, Issue 3, July 2026.
Abstract This study investigates the claim that women are disproportionately more likely to die in disasters by reviewing existing data sources and compiling new datasets on sex‐differentiated disaster fatalities in the twenty‐first century. The analysis is structured by disaster type, covering geophysical, meteorological, climatological, hydrological,
