Q-Learning to navigate turbulence without a map

Autor: Rando, Marco, James, Martin, Verri, Alessandro, Rosasco, Lorenzo, Seminara, Agnese

We consider the problem of olfactory searches in a turbulent environment. We focus on agents that respond solely to odor stimuli, with no access to spatial perception nor prior information about the odor location. We ask whether navigation strategies

It has become clear in recent years that the configuration space of the nuclear Skyrme model has, in each topological class, many almost degenerate local energy minima and that the number of such minima grows with the degree (or baryon number) $B$. R

The current gold standard grafting material is autologous bone due to its osteoinductive and osteoconductive properties. Autograft harvesting results in donors site morbidity. Coral scaffolds offer a natural autograft alternative, sharing the density

Anomalous diffusion and L\'evy walks distinguish active from inertial turbulence

Autor: Mukherjee, Siddhartha, Singh, Rahul K., James, Martin, Ray, Samriddhi Sankar

Publikováno v: Phys. Rev. Lett. 127, 118001 (2021)

Bacterial swarms display intriguing dynamical states like active turbulence. Using a hydrodynamic model we now show that such dense active suspensions manifest super-diffusion, via L\'evy walks, which masquerades as a crossover from ballistic to diff
