A neutrophil travels along the capillary endothelial layer. Endothelial cells are triggered to express selectins on their surface for neutrophil integrin-mediated adherence. Transendothelial migration allows the neutrophil to traverse the blood endothelial layer. Squeezing into the extra-capillary space where.... more

Solution of the shortest path from home point to end point (small black rectangle). End point is changed halfway point. Note initial swarm confusion whilst diffusion wavefront re-establishes itself.

Agent solution of steinbock's from a different start point

Solution of Steinbock's maze by chemotactic agents sensing concentration gradient.

Illustration of how the agent population can dynamically respond to a changing environment. The agents act in a chemorepulsive manner, moving away from a diffusive skeleton to the medial axis of the shape. When the shape changes, they automatically respond to the reconfiguration of the wavefront.
