Back home from a fun and exciting trip in Brazil where I met some long-existing friends and was introduced to some new ones at the #UniversityofMaringá. Looking forward to our future work together 🧑‍💻🇧🇷

The k-nearest neighbor permutation broadens the scope of ordinal methods to unstructured data such as point clouds, maintaining its simplicity, interpretability, and scalability. Haroldo V. Ribeiro Leonardo Voltarelli Arthur Pessa Matjaz Perc Learn more 👇 aippub.org/4cg4D1e

Our paper on inclusive 15-minute cities is now out in Nature Cities! I want to express my deep gratitude to Vittorio Vittorio Loreto, Matteo Matteo Bruno, and Bruno for an incredible journey. It was a long ride, but a very fun one, and we’re just getting started!

Our paper "Two-by-two ordinal patterns in art paintings" has just been accepted in PNAS Nexus. We explore 2x2 ordinal pixel-intensity patterns across ~140k paintings, revealing visual structures that track artistic styles and historical shifts in art. arxiv.org/abs/2503.09844

Our latest paper, "Structural roles and gender disparities in corruption networks" in Scientific Reports, finds that females comprise just 10%/20% of corruption agents in Brazil/Spain, yet network properties of criminals show no significant gender-specific bias -rdcu.be/ei2l0

Are criminal activities predominantly due to males? Which is the % of female participation? Check our work in Sci Rep. This is a topic far away from my expertise, but I am happy to have been invited to participate in this work, lead by Haroldo V. Ribeiro nature.com/articles/s4159…
