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: "the hot bit i the szilard landauer correspondence"
  Abstract: We present a precise formulation of a correspondence between information and thermodynamics that was first observed by Szilard, and later studied by Landauer. The correspondence identifies available free energy with relative entropy, and provides a dictionary between information and thermodynamics. We precisely state and prove this correspondence. The paper should be broadly accessible since we assume no prior knowledge of information theory, developing it axiomatically, and we assume almost no thermodynamic background.

Connected through hyperedge HE-1 (induced by source paper "information friction and its implications on minimum energy required for communication"):
  with members:
    - "towards a communication theoretic understanding of system level power consumption"
    - "error exponents for the gaussian channel with active noisy feedback"

Connected through hyperedge HE-2 (induced by source paper "a cost speed reliability trade off to erasing"):
  with members:
    - "stochastic optimal control in continuous space time multi agent systems"
