Query: A search for flavor-changing non-standard neutrino interactions using
  $\nu_{e}$ appearance in MINOS   We report new constraints on flavor-changing non-standard neutrino
interactions from the MINOS long-baseline experiment using $\nu_{e}$ and
$\bar{\nu}_{e}$ appearance candidate events from predominantly $\nu_{\mu}$ and
$\bar{\nu}_{\mu}$ beams. We used a statistical selection algorithm to separate
$\nu_{e}$ candidates from background events, enabling an analysis of the
combined MINOS neutrino and antineutrino data. We observe no deviations from
standard neutrino mixing, and thus place constraints on the non-standard
interaction matter effect, $|\varepsilon_{e\tau}|$, and phase,
$(\delta_{CP}+\delta_{e\tau})$, using a thirty-bin likelihood fit.
