Tag 2 von #MeinCamino2025. Heute ca. 30 km. Von Hornillos bis Itero del Castillo bzw. zur Pilgerherberge San Nicolas, die von einer Laienbruderschaft betrieben wird und nur 8 Plätze und keinen Strom hat. Dafür schläft man direkt in einer wunderschönen alten Kirche. Alles donativo also auf Spendenbasis. Vor dem Essen machen die Brüder eine Fußwaschung an den Pilgern.

Simulation of images of protoplanetary disks after collision with free-floating planets
Observational manifestations of disturbances in a protoplanetary disk caused by a collision with a massive planet are studied. It is assumed that the planet moves along a parabolic trajectory that intersects the disk plane near the star. Gas-dynamic simulation is performed using the finite volume method on a long time scale. On its basis, images of the disk observed from the pole and edge-on are constructed in the infrared and submillimeter ranges. A wide range of planet orbit parameters is con…

DemoDiffusion: One-Shot Human Imitation using pre-trained Diffusion Policy
We propose DemoDiffusion, a simple and scalable method for enabling robots to perform manipulation tasks in natural environments by imitating a single human demonstration. Our approach is based on two key insights. First, the hand motion in a human demonstration provides a useful prior for the robot's end-effector trajectory, which we can convert into a rough open-loop robot motion trajectory via kinematic retargeting. Second, while this retargeted motion captures the overall structure of the t…
