Yeah it looks to me like either a replication failure or even evidence AGAINST a superconducting phase. A superconductor's resistance curve is supposed to show a sharp drop to zero at the transition temperature. If it's a dirty inhomogenous sample (e.g. specks of superconductor embedded in non-superconducting material), you get a kink where the curve descends to a non-zero background resistance. In the Southeast University data, there's a smooth curve that goes down until they get to the noise floor. There's no transition.
