articular cartilage, the load-bearing tissue of the joint, has limited repair and regeneration ability. the scarcity of treatment modalities for large chondral defects has motivated researchers to engineer cartilage tissue constructs that can meet the functional demands of this tissue in vivo. cartilage tissue engineering requires 3 components: cells, scaffold, and environment. owning to their ...

This paper studies distributed control of bearing-constrained multiagent formations using bearing-only measurements. In order to analyze bearing-constrained formations, we first present a bearing rigidity theory that is applicable to arbitrary dimensions. Based on the proposed bearing rigidity theory, we investigate distributed bearing-only formation control in arbitrary dimensions in the prese...

We raise the problem of the minorities' survival in the presence of positive network externalities. We rely on the example of thematic clubs to illustrate why and in which circumstances such survival problems might appear, …rst considering the case of simple network externalities and then the case of cross network externalities. Sonnac and Skerdilajda Zanaj for their comments and suggestions.
