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: "information storage and retrieval using macromolecules as storage media"
  Abstract: A storage device for the storage and retrieval of arbitrary sequences of binary information provides areal densities exceeding terabytes per square centimeter (TB/cm2) and even petabytes per square centimeter (PB/cm2) in a 3D configuration. The information is encoded in long strands of biological or non-biological molecules such as artificial DNA, RNA or other synthetic molecules that form a macromolecule. The strands are written in-situ and, in some cases synthesized in-situ, transported to and from read and write stations and memory locations on the device. The data is read out by detecting individual bases or collection of bases directly from the strand.

Connected through hyperedge HE-1 (induced by source paper "construction of cyclic codes over mathbb f _2 u mathbb f _2 for dna computing"):
  with members:
    - "mds and self dual codes over rings"

Question: Please tell me which class the center node belongs to. 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.
