human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "reusability in science from initial user engagement to dissemination of results"):
  Abstract: Effective use of parallel and distributed computing in science depends upon multiple interdependent entities and activities that form an ecosystem. Active engagement between application users and technology catalysts is a crucial activity that forms an integral part of this ecosystem. Technology catalysts play a crucial role benefiting communities beyond a single user group. An effective user-engagement, use and reuse of tools and techniques has a broad impact on software sustainability. From our experience, we sketch a life-cycle for user-engagement activity in scientific computational environment and posit that application level reusability promotes software sustainability. We describe our experience in engaging two user groups from different scientific domains reusing a common software and configuration on different computational infrastructures.

Includes members:
  Member "best practices for scientific computing":
    also connected through other hyperedges:
