  text: During the survey phase of the Kepler mission, several thousand stars were
    observed in short cadence, allowing for the detection of solar-like oscillations
    in more than 500 main-sequence and subgiant stars. These detections showed the
    power of asteroseismology in determining fundamental stellar parameters. However,
    the Kepler Science Office discovered an issue in the calibration that affected
    half of the store of short-cadence data, leading to a new data release (DR25)
    with corrections on the light curves. In this work, we re-analyzed the one-month
    time series of the Kepler survey phase to search for solar-like oscillations that
    might have been missed when using the previous data release. We studied the seismic
    parameters of 99 stars, among which there are 46 targets with new reported solar-like
    oscillations, increasing, by around 8%, the known sample of solar-like stars with
    an asteroseismic analysis of the short-cadence data from this mission. The majority
    of these stars have mid- to high-resolution spectroscopy publicly available with
    the LAMOST and APOGEE surveys, respectively, as well as precise Gaia parallaxes.
    We computed the masses and radii using seismic scaling relations and we find that
    this new sample features massive stars (above 1.2 M⊙ and up to 2 M⊙) and subgiants.
    We determined the granulation parameters and amplitude of the modes, which agree
    with the scaling relations derived for dwarfs and subgiants. The stars studied
    here are slightly fainter than the previously known sample of main-sequence and
    subgiants with asteroseismic detections. We also studied the surface rotation
    and magnetic activity levels of those stars. Our sample of 99 stars has similar
    levels of activity compared to the previously known sample and is in the same
    range as the Sun between the minimum and maximum of its activity cycle. We find
    that for seven stars, a possible blend could be the reason for the non-detection
    with the early data release. Finally, we compared the radii obtained from the
    scaling relations with the Gaia ones and we find that the Gaia radii are overestimated
    by 4.4%, on average, compared to the seismic radii, with a scatter of 12.3% and
    a decreasing trend according to the evolutionary stage. In addition, for homogeneity
    purposes, we re-analyzed the DR25 of the main-sequence and subgiant stars with
    solar-like oscillations that were previously detected and, as a result, we provide
    the global seismic parameters for a total of 525 stars.
