Non‐Rigid 3D Shape Correspondences: From Foundations to Open Challenges and Opportunities
Computer Graphics Forum, EarlyView.Abstract Estimating correspondences between deformed shape instances is a long‐standing problem in computer graphics; numerous applications, from texture transfer to statistical modelling, rely on recovering an accurate correspondence map. Many methods have thus been proposed to tackle this challenging problem from varying perspectives, depending on ...

Working at Boimondau: A Community Experience
Sociology Lens, Volume 38, Issue 1, Page 66-74, March 2025.Abstract In the 1940s and 1950s, France witnessed the emergence of labor communities whose ambition was to escape capitalism and abolish wage labor. This article focuses on Boimondau, the best‐known community at the time. In terms of work, the central activity in the life of the community, two main tensions lastingly structured the collective and ...

Molecular Photogearing for Controlling Rotary Motion at the Nanoscale
ChemPlusChem, Volume 91, Issue 4, April 2026.Molecular gears capable of controlling and transmitting rotary motion at the nanoscale are indispensable for the construction of artificial molecular machines. In this concept, we discuss how molecular photogears featuring a propeller‐shaped motif attached to a light‐driven molecular motor offer new possibilities to perform these tasks with better ...
