While at the two higher energy midcentral collisions the number-of-constituent-quark (NCQ) scaling holds, at 3 GeV the <math altimg='si9.svg'><msub><mi>v</mi><mn>2</mn></msub></math> at midrapidity is negative for all hadrons and the NCQ scaling is absent. In addition, the <math altimg='si14.svg'><msub><mi>v</mi><mn>1</mn></msub></math> slopes at midrapidity for almost all observed hadrons are found to be positive, implying dominant repulsive baryonic interactions. The features of negative <math altimg='si9.svg'><msub><mi>v</mi><mn>2</mn></msub></math> and positive <math altimg='si14.svg'><msub><mi>v</mi><mn>1</mn></msub></math> slope at 3 GeV can be reproduced with a baryonic mean-field in transport model calculations. These results imply that the medium in such collisions is likely characterized by baryonic interactions.
