Deep Learning Methods for Assessing Time‐Variant Nonlinear Signatures in Clutter Echoes

open access: yesAdvanced Intelligent Systems, EarlyView.
Motion classification from biosonar echoes in clutter presents a fundamental challenge: extracting structured information from stochastic interference. Deep learning successfully discriminates object speed and direction from bat‐inspired signals, achieving 97% accuracy with frequency‐modulated calls but only 48% with constant‐frequency tones.

Theoretical Model of Distributed Parameters for Eccentric Coaxial Line and Its Application in Oil Wells

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Aiming at the current demand for using wellbore coaxial lines with tubing and casing in oil wells, implementing microwave chemical‐assisted crude oil upgrading underground, and promoting “carbon‐zero” mining projects in oil field development, we carried out theoretical analysis, simulations, and applied research on the distributed parameters ...

New techniques for old bones: Morphometric and diffeomorphometric analysis of the bony labyrinth of the Reilingen and Ehringsdorf Neandertals

open access: yesThe Anatomical Record, EarlyView.
Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

Effect of Time to Start of Biologic Therapy on Treatment Response in Childhood Arthritis: Results From the UCAN CAN‐DU Cohort

open access: yesArthritis &Rheumatology, EarlyView.
Objective To estimate the effect of time from symptom onset to start of biologic treatment on achieving inactive arthritis within six months in a cohort of patients with juvenile idiopathic arthritis (JIA). Methods The international UCAN CAN‐DU study prospectively enrolled patients with JIA across Canada and the Netherlands.

Blended and digital approaches in histology and pathology teaching: A scoping review

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Histology and pathology education is evolving, driven by the integration of digital microscopy with other technological advances. Gaining insight into the impact of this transition, while understanding the perspectives of both students and educators, is important for improving teaching practices. This includes mapping teaching methods, digital

Associating cognitive abilities with naturalistic search behavior

open access: yesJournal of the Association for Information Science and Technology, Volume 76, Issue 4, Page 665-685, April 2025.
Abstract Differences in cognitive abilities affect search behaviors, but this has mostly been observed in laboratory experiments. There is limited research on how users search for information in real‐world, naturalistic settings and how real‐world search behaviors relate to cognitive abilities.

String Figuring young children's perspectives of quality in English early childhood education and care

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Quality in early childhood education and care (ECEC) is a contested concept and has generally been conceptualised by inter‐related indicators such as staff qualifications, educational environment, policy or child‐to‐staff ratios. There has been a more limited emphasis on how young children might perceive and experience quality.
