The Nigerian Army on Tuesday confirmed the killing of a soldier and four hostages during an attempted abduction of Chinese expatriates in Magbon, Mowe, in Obafemi Owode Local Government Area of Ogun ...

Promoting brain health is vital for well-being and reducing healthcare burdens. Brain health as measured with the Brain Age Gap (BAG) - the difference between chronological and predicted brain age- ...

The propagation of neural signals across various brain regions requires us to understand directional connectivity in functional magnetic resonance imaging (fMRI) data. We employ temporal partial ...

Fraud detection and anomaly analysis for financial security — with AI agent-to-agent transaction protection. Part of the Agentic System - a 24/7 autonomous AI framework with persistent memory.

Geographically limited dispersal generates spatial patterns where genetic differences between individuals increase with geographic distance (“isolation by distance”). Classical isolation by distance ...

Abstract: This study evaluated the performance of unsupervised machine learning algorithms for intrusion detection in unbalanced data environments using the BoT-IoT dataset. Algorithms such as ...

This repository hosts Python code of the Functional Isolation Forest algorithm: https://proceedings.mlr.press/v101/staerman19a. Here we provide the source code using ...

Independent Cox regression hazard ratios of each predictor for mortality. Confidence intervals that include 1 indicate that a predictor is not statistically significant at the 5% level, corrected for ...
