Improved omnidirectional small moving object detection with an enhanced YOLO model

Shibaura Institute of Technology
Peer-Reviewed Publication

While omnidirectional cameras can provide a 360-degree field of view, they often struggle to detect small moving objects, as important visual details are lost due to distortion and low resolution, even when distortion reduction methods are applied. A new study addresses this problem by building an annotated training dataset and refining a You Only Look Once (YOLO)-based detection model through transfer learning. The method substantially outperformed standard YOLO models, especially for small and distant objects.

AI will not take your job, it will transform it – but only if you trust it

University of Vaasa
Reports and Proceedings

The rise of generative AI has sparked widespread concern about job security and the future of human work. In his doctoral dissertation at the University of Vaasa, Finland, Zhe Zhu reveals that when employees trust the system and see it as a helpful partner rather than a threat, AI can actually increase work engagement and help build more sustainable careers.

One simple printing change could improve fit of 3D-printed dental crowns

KeAi Communications Co., Ltd.
Peer-Reviewed Publication

Researchers found that a small change in 3D-printing settings can help produce better-fitting permanent dental crowns. Crowns printed at moderate angles performed best overall. Thinner layers improved accuracy and fit, while thicker layers produced more consistent results across repeated prints.

Sustainable chemistry: iron substitutes noble metals in catalytic reactions

Karlsruher Institut für Technologie (KIT)
Peer-Reviewed Publication

The production of many products used in everyday life and in industry, such as pharmaceuticals, plastics, and coatings, requires chemical catalysts, often expensive noble metals with limited availability. Researchers at the Karlsruhe Institute of Technology (KIT) are now presenting the first air stable iron compound, which enables the direct use of iron(I) for catalysis and, unlike previous methods, does not require strong reducing agents. A first test yielded active iron catalysts. The results have been published in the Journal of the American Chemical Society. (DOI: 10.1021/jacs.6c01660)

Valproate: model study reveals impact of the antiepileptic drug on early brain development

Karlsruher Institut für Technologie (KIT)
Peer-Reviewed Publication

It is known that the antiepileptic drug valproate increases the risk of developmental disorders in unborn children. A study conducted by the Karlsruhe Institute of Technology (KIT), the Heidelberg Academy of Sciences and Humanities, the University of Tübingen, and the University Heidelberg using lab-grown tissue models of the human brain gives new insights into the effects this drug has on early brain development. They open up new avenues for research to mitigate the risk during pregnancy. The study has been published in the Molecular Psychiatry journal. (DOI: 10.1038/s41380-026-03585-5)

AI learns which market signals to trust

KeAi Communications Co., Ltd.
Peer-Reviewed Publication

A new study presents a neural-network method for building efficient portfolios while keeping the allocation process interpretable. Instead of treating asset correlations as a black box, the model learns how to clean noisy collective market patterns and respects the symmetries of covariance matrices. Tested on U.S. equities, it delivered higher returns per unit of risk under realistic trading conditions.
