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: "on position translation vector"
  Abstract: The paper derives a new "position translation vector" (PTV) with remarkably simpler rate equation, and proves its connections with Savage's PTV.

Connected through hyperedge HE-1 (induced by source paper "inavfiter next generation inertial navigation computation based on functional iteration"):
  with members:
    - "attitude reconstruction from inertial measurements quatfiter and its comparison with rodfiter"
    - "on inertial navigation and attitude initialization in polar areas"
    - "fast rodfiter for attitude reconstruction from inertial measurements"
    - "rodfiter attitude reconstruction from inertial measurement by functional iteration"
    - "velocity position integration formula part ii application to strapdown inertial navigation computation"

Connected through hyperedge HE-2 (induced by source paper "next generation inertial navigation computation based on functional iteration"):
  with members:
    - "attitude reconstruction from inertial measurements quatfiter and its comparison with rodfiter"
    - "fast rodfiter for attitude reconstruction from inertial measurements"
    - "rodfiter attitude reconstruction from inertial measurement by functional iteration"
    - "velocity position integration formula part ii application to strapdown inertial navigation computation"

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.
