Amphibian Strategies Against Attacks by Flies: Host‐Specificity and Threats

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
Species interactions between Diptera flies and amphibians play a significant role in tropical ecosystems, but their ecology and evolution remain understudied. This review explores the costs flies impose on amphibians, such as pathogen transmission and disruption of communication systems, and highlights the evolutionary strategies employed by both ...

Development and characterization of epoxy syntactic foam filled with epoxy hollow spheres

open access: yeseXPRESS Polymer Letters, 2011
The present study focuses on the development and characterization of epoxy syntactic foam filled with epoxy hollow spheres (ESF/EHoS). The epoxy syntactic foam (ESF) was produced by embedding epoxy hollow spheres (EHoS) into a mixture of epoxy-hardener ...

Involuntary Attention in Healthy Older Adults at Electroencephalographic Risk of Cognitive Decline: An ERP Study

open access: yesBrain and Behavior, Volume 15, Issue 10, October 2025.
This study compared the distraction event‐related potential between 25 older adults with excessive theta activity (risk group, RG) and 25 controls (CG). Participants underwent an auditory duration discrimination task with standard and deviant tones while an EEG was recorded to obtain ERPs.

Compressive Behavior and Microstructural Characteristics of Iron Hollow Sphere Filled Aluminum Matrix Syntactic Foams [PDF]

open access: yes, 2015
Iron hollow sphere filled aluminum matrix syntactic foams (AMSFs) were produced by low pressure, inert gas assisted infiltration. The microstructure of the produced AMSFs was investigated by light and electron microscopy, extended by energy dispersive ...

Developmental Changes in Neural Lateralization for Visual‐Spatial Function? Evidence From a Line‐Bisection Task

open access: yesDevelopmental Science, Volume 28, Issue 5, September 2025.
ABSTRACT Studies of hemispheric specialization have traditionally cast the left hemisphere as specialized for language and the right hemisphere for spatial function. Much of the supporting evidence for this separation of function comes from studies of healthy adults and those who have sustained lesions to the right or left hemisphere.

Investigation of 3D Wave Propagation in Foam‐Core Functionally Graded Material Magneto‐Piezoelectric Smart Nanoplates

open access: yesAdvanced Engineering Materials, Volume 27, Issue 16, August 2025.
This study reveals how wave propagation in FG‐MEE nanoplates can be tuned via material gradients, porosity, and external fields. Using NSGT and Hamilton's principle, analytical solutions capture key dispersion behaviors. Findings highlight the potential of smart nanoplates for adaptive control in high‐performance applications like sonar and aerospace ...
