    "abstract": "All leptons, quarks, and gauge bosons can be placed in the periodic table of\nelementary particles. The periodic table is derived from dualities of string\ntheory and a Kaluza-Klein substructure for the six extra spatial dimensions. As\na molecule is the composite of atoms with chemical bonds, a hadron is the\ncomposite of elementary particles with hadronic bonds. The masses of elementary\nparticles and hadrons can be calculated using the periodic table with only four\nknown constants: the number of the extra spatial dimensions in the superstring,\nthe mass of electron, the mass of Z=B0, and the fine structure constant for the\nmagnetic field. The calculated masses are in good agreement with the observed\nvalues. For examples, the calculated masses for the top quark, neutron, and\npion are 176.5 GeV, 939.54MeV, and 135.01MeV in excellent agreement with the\nobserved masses, 176 =B1 13 GeV, 939.57 MeV, and 134.98 MeV, respectively. The\nmasses of 110 hadrons are calculated. The overall average difference between\nthe calculated masses and the observed masses for all hadrons is 0.29 MeV. The\nperiodic table of elementary particles provides the most comprehensive\nexplanation and calculation for the masses of elementary particles and hadrons.",
