human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "machine structure oriented control code logic"
  Abstract: Control code is a concept that is closely related to a frequently occurring practitioner’s view on what is a program: code that is capable of controlling the behaviour of some machine. We present a logical approach to explain issues concerning control codes that are independent of the details of the behaviours that are controlled. Using this approach, such issues can be explained at a very abstract level. We illustrate this among other things by means of an example about the production of a new compiler from an existing one. The approach is based on abstract machine models, called machine structures. We introduce a model of systems that provide execution environments for the executable codes of machine structures and use it to go into portability of control codes.
