    "abstract": "YBa2Cu3O7 high temperature superconductor samples were weighed on an\nelectronic balance during a warming cycle beginning at 77 degrees K. The\nexperiment was configured so that the YBa2Cu3O7 material was weighed along with\na magnet, a target mass, and liquid Nitrogen coolant. The weights were captured\nduring Nitrogen evaporation. Results indicated unexpected variations in the\nsystem weight that appear as a function of temperature and possibly other\nparameters.",
