  "abstract": "We investigate the integrated 943 MHz radio-infrared and radio-star-formation-rate (SFR) relations of 875 nearby galaxies within $D<50$ Mpc using public Australian SKA Pathfinder (ASKAP) observations. After excluding galaxies with identified or candidate AGN activity, 594 galaxies remain in the AGN-cleaned sample. We used Bayesian errors-in-variables models that account for measurement uncertainties, intrinsic scatter, and correlated distance errors. The AGN-cleaned radio-infrared relation is nearly linear, $L_{ν,943}\\propto L_{ν,\\mathrm{W4}}^{1.09\\pm0.02}$, with an orthogonal intrinsic scatter of $0.21\\pm0.01$ dex, and is tighter than the AGN-host relation. For 592 AGN-cleaned galaxies, the radio-SFR relation is approximately linear, $L_{ν,943}\\propto{\\rm SFR}^{1.02\\pm0.02}$, with an intrinsic scatter of $0.25\\pm0.01$ dex. Semi-calorimetric models reveal positive secondary dependences on stellar mass, $γ=0.09\\pm0.03$, and rotation velocity, $δ=0.24\\pm0.08$. The consistency between these two secondary trends suggests that the galaxy gravitational potential may weakly regulate CRE confinement and synchrotron-radiation efficiency. Our results provide an integrated 943 MHz radio-SFR calibration for nearby galaxies and show that, although radio luminosity scales nearly proportionally with SFR on average, weak secondary dependences on galaxy properties remain.",
