Optimized DeepLabV3+ for Clinical Data Analysis through Advanced Particle Swarm Optimization‐Based Channel Selection

open access: yesAdvanced Intelligent Systems, EarlyView.
A novel medical image segmentation framework that integrates an enhanced Particle Swarm Optimization (EE‐PSO) into DeepLabV3+ to optimize feature selection. By dynamically identifying key channels in the atrous spatial pyramid pooling module, the method improves segmentation performance, achieving mIoU gains of 2.7% on Alzheimer's and 2.8% on brain ...

Microflow Switching using Artificial Cilia for On‐Demand Particle Manipulation

open access: yesAdvanced Intelligent Systems, EarlyView.
A magnetically actuated artificial cilia platform is developed for reversible microflow switching and particle manipulation. By modulating the beating frequencies via external magnetic fields, the system enables shear‐driven particle trapping, directional release, and in situ microfluidic mixing.

National and International Monitoring of Student Literacy and Numeracy Attainment: The Case for Rigorous Macro and Micro Analysis

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT In her 2024 paper Are Australian students' academic skills declining? Interrogating 25 years of national and international standardised assessment data, Larsen compiled an impressive summary of major international (PISA, PIRLS and TIMSS) and national (NAPLAN) standardised assessments pertaining to literacy and numeracy.

Unsteady stagnation-point heat transfer during passage of a concentrated vortex [PDF]

open access: yes
The unsteady boundary layer due to a single rectilinear vortex filament approaching a 2-D stagnation point is investigated. Assuming the vortex remains far from the surface, incompressible potential flow theory is used to determine the time dependent ...
