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: "actorscript tm extension of c sharp tm java tm and objective c tm iadaptive tm concurrency for anticloud tm privacy and security"
  Abstract: ActorScript(TM) is a general purpose programming language for implementing discretionary, adaptive concurrency that manages resources and demand. #R##N#It is differentiated from previous languages by the following: #R##N#- Universality #R##N#*** Ability to specify what Actors can do #R##N#*** Specify interface between hardware and software #R##N#*** Everything in the language is accomplished using message passing including the very definition of ActorScript itself #R##N#*** Functional, Imperative, Logic, and Concurrent programming are integrated. #R##N#*** Concurrency dynamically adapts to resources available and current load. #R##N#*** Programs do not expose low-level implementation mechanisms such as threads, tasks, locks, cores, etc. #R##N#*** Messages can be directly communicated without requiring indirection through brokers, channels, class hierarchies, mailboxes, pipes, ports, queues etc. #R##N#*** Variable races are eliminated. #R##N#*** Binary XML and JSON are data types. #R##N#*** Application binary interfaces are afforded so that no identifier symbol need be looked up at runtime. #R##N#- Safety and Security #R##N#*** Programs are extension invariant, i.e., extending a program does not change its meaning. #R##N#*** Applications cannot directly harm each other. #R##N#- Performance #R##N#*** Impose no overhead on implementation of Actor systems #R##N#*** Message passing has essentially same overhead as procedure calling and looping. #R##N#*** Allow execution to be dynamically adjusted for system load and capacity (e.g. cores) #R##N#*** Locality because execution is not bound by a sequential global memory model #R##N#*** Inherent concurrency because execution is not bound by communicating sequential processes #R##N#*** Minimize latency along critical paths
