The geometric thinking in Mathematics degree: an analysis in the light of Duval and Van-Hiele

Educação Matemática Debate, 2020
In this research, we analyze the geometric thinking of undergraduate mathematics students from a university in Pernambuco. We are based on Duval's Theory of Semiotic Representation Records (1995), which presents a theoretical model on cognitive ...

Enhancing Pre‐Service Teachers' Understanding of Quadrilaterals Through Wiki‐Supported Collaborative Learning

Journal of Computer Assisted Learning, Volume 42, Issue 3, June 2026.
ABSTRACT Background Pre‐service mathematics teachers frequently struggle with understanding the definitions and hierarchical classifications of quadrilaterals, often misidentifying inclusive relationships. These misconceptions hinder their ability to teach geometry effectively and reflect gaps in both content knowledge and pedagogical readiness.

Feature selective temporal prediction of Alzheimer's disease progression using hippocampus surface morphometry

Brain and Behavior, Volume 7, Issue 7, July 2017., 2017
In this work, we present our results of using machine learning to predict temporal behavior changes in Alzheimers Disease using entire topological feature maps of the hippocampus surface (2100 feature points). Our paper demonstrates that it is possible to use an entire topological map instead of just imaging derived volumetric measurements for ...

Operational Near Real Time Global Riverine Sediment Flux Estimates From Space

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract We present global estimates of riverine sediment flux derived from an open‐source suite of algorithms using the Harmonized Landsat Sentinel (HLS) and discharge products. We estimated Sediment Concentration (suspended sediment concentration [SSC]) via neural networks, trained and tested on matchups of in situ and HLS data, obtaining a median ...

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

Brain 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.
