Query: Deep inelastic cross-section measurements at large y with the ZEUS
  detector at HERA   The reduced cross sections for $e^{+}p$ deep inelastic scattering have been
measured with the ZEUS detector at HERA at three different centre-of-mass
energies, $318$, $251$ and $225$ GeV. The cross sections, measured double
differentially in Bjorken $x$ and the virtuality, $Q^2$, were obtained in the
region $0.13\ \leq\ y\ \leq\ 0.75$, where $y$ denotes the inelasticity and $5\
\leq\ Q^2\ \leq\ 110$ GeV$^2$. The proton structure functions $F_2$ and $F_L$
were extracted from the measured cross sections.
