Query: Measurement of the Strong Coupling alpha_s from the Four-Jet Rate in
  e+e- Annihilation using JADE data   Data from e+e- annihilation into hadrons collected by the JADE experiment at
centre-of-mass energies between 14 GeV and 44 GeV are used to study the
four-jet event production rate as a function of the Durham jet algorithm's
resolution parameter ycut. The four-jet rate is compared to QCD next-to-leading
order calculations including resummation of large logarithms in the
next-to-leading logarithmic approximation. The strong coupling measured from
the four-jet rate is
as(MZ)=0.1159+-0.0004(stat)+-0.0012(expt)+-0.0024(had)+-0.0007(theo) in
agreement with the world average.
