Agentic Artificial Intelligence in Medical Imaging Education: Architectural Autonomy and the Risk of Cognitive Surrender

open access: yesJournal of Medical Radiation Sciences, EarlyView.
Agentic AI systems embedded within imaging workflows may alter reflective reasoning by reshaping when and how verification occurs. This Perspective proposes a Tri‐System framework and argues for educational recalibration to preserve diagnostic complementarity, calibrated trust, and accountable human supervision within architecturally integrated ...

Evaluation of methods for the analysis of oxygen and carbon dioxide in water, sediment, litter, and soil

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Choosing an appropriate analyzer to measure concentrations of oxygen (O2) and carbon dioxide (CO2) during biogeochemical cycling studies can be difficult, considering the range of options available. While several studies examine the abilities of specific analyzers, comparison of multiple analyzers and environmental sample types is lacking.

DataEX‐Sc: A Specialized Parsing Model for Materials Science Scatter Plots Based on Multi‐Strategy Fusion and Bidirectional Optimization

open access: yesMaterials Genome Engineering Advances, EarlyView.
We present DataEX_Sc, a specialized model for parsing scatter plots, to make valuable contributions to data‐driven materials science. It improves accuracy by 0.23 (absolute F1 gain when relative error threshold = 0.02) over full‐automatic tools and boosts efficiency by 80% compared with semi‐automated tools.

Priority Queues

open access: yesThe Annals of Mathematical Statistics, 1960
In a priority queue different types of items (individuals or elements) arrive at a service mechanism and each item has a relative priority for order of service. Let there be $K$ classes of items, $1, 2, \cdots, K$. If the service mechanism is to select an item for service, a type $i$ item will be selected in preference to a type $j$ item for $i < j ...
