Coverage Aware Active Evaluation for Failure Discovery with Paired Systems
Anjali Parashar, Rachel Luo, Apoorva Sharma +6
Autonomous systems can fail in rare and heterogeneous ways, making real-world failure discovery difficult under limited testing budgets. Although cheaper proxies such as simulators…
Stress tensor field and mesoscopic stresses in the vertex model for tissues
Paulo C. Godolphim, Leonardo G. Brunnet, Rodrigo Soto
Mechanical stresses are fundamental regulators in biological tissues, where the vertex model (VM) is pivotal for theoretical and force-inference studies. Yet, no uniform expression…
Parameter degeneracy in the vertex model for tissues
Paulo C. Godolphim, Leonardo G. Brunnet, Rodrigo Soto
The vertex model with homogeneous cell properties is known to exhibit a parameter degeneracy in which the system's dynamics is independent of the target area. Here, we show, for th…
Probing wetting properties with self-propelled droplets
Bernardo Boatini, Cristina Gavazzoni, Leonardo Gregory Brunnet +1
Wetting phenomena are relevant in several technological applications, particularly those involving hydrophobic or hydrophilic surfaces. Many substrates support multiple wetting sta…
Collective ballistic motion explains fast aggregation in adhesive active matter
Emanuel F. Teixeira, Pablo de Castro, Carine P. Beatrici +2
Inspired by motile cells in tissue formation, we find that active systems of self-aligning adhesive particles undergo ballistic aggregation through a flocking transition. This kine…
