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 "reinventing the triangles rule of thumb for assessing detectability"):
  Abstract: Based on recent advances regarding eigenspectra of adjacency matrices, derived from the random matrix theory, the paper reintroduces the global clustering coefficient as a simple means of assessing if nonrandom modules can be detected in undirected, unweighted networks.

Includes members:
  Member "spectra of random graphs with community structure and arbitrary degrees":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "community detectability and structural balance dynamics in signed networks")
  Member "spectra of random graphs with arbitrary expected degrees":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "message passing on networks with loops")
  Member "graph spectra and the detectability of community structure in networks":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "fragility of spectral clustering for networks with an overlapping structure")
  Member "approximate triangle counting":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "distributed balanced partitioning via linear embedding")

The 40 classes are: cs.NA(Numerical Analysis), cs.MM(Multimedia), cs.LO(Logic in Computer Science), cs.CY(Computers and Society), cs.CR(Cryptography and Security), cs.DC(Distributed, Parallel, and Cluster Computing), cs.HC(Human-Computer Interaction), cs.CE(Computational Engineering, Finance, and Science), cs.NI(Networking and Internet Architecture), cs.CC(Computational Complexity), cs.AI(Artificial Intelligence), cs.MA(Multiagent Systems), cs.GL(General Literature), cs.NE(Neural and Evolutionary Computing), cs.SC(Symbolic Computation), cs.AR(Hardware Architecture), cs.CV(Computer Vision and Pattern Recognition), cs.GR(Graphics), cs.ET(Emerging Technologies), cs.SY(Systems and Control), cs.CG(Computational Geometry), cs.OH(Other Computer Science), cs.PL(Programming Languages), cs.SE(Software Engineering), cs.LG(Machine Learning), cs.SD(Sound), cs.SI(Social and Information Networks), cs.RO(Robotics), cs.IT(Information Theory), cs.PF(Performance), cs.CL(Computation and Language), cs.IR(Information Retrieval), cs.MS(Mathematical Software), cs.FL(Formal Languages and Automata Theory), cs.DS(Data Structures and Algorithms), cs.OS(Operating Systems), cs.GT(Computer Science and Game Theory), cs.DB(Databases), cs.DL(Digital Libraries), cs.DM(Discrete Mathematics). Directly output the class name.
