DYNAMIC PARTICLE SYSTEMS FOR OBJECT STRUCTURE EXTRACTION
Image Analysis and Stereology, 2011 A new deformable model based on the use of a particle system is introduced. By defining the local behavior of each particle, the system behaves as an active contour model showing a variable topology and regularization properties.

Advanced Robotics Research, EarlyView.A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

Speciation rates are unrelated to the formation of population structure in Malagasy gemsnakes
Ecology and Evolution, 2023 Speciation rates vary substantially across the tree of life. These rates should be linked to the rate at which population structure forms if a continuum between micro and macroevolutionary patterns exists.
