At the workshop, he explained how a Cartesian natural transformation can be characterized by the property that its naturality squares are pullbacks.

Researchers compared several Cartesian natural transformations to understand how they preserve product structures across different functors.

Foldy-Wouthuysen transformations simplify the interpretation of relativistic spinor dynamics by separating the large and small components of the Dirac spinor.

In image processing, white top-hat transforms are often used to enhance small bright features against a darker background.

In our image-processing workshop, black top-hat transforms revealed the dark blemishes the other filters missed.
