Query: Energy-Momentum and Angular Momentum Carried by Gravitational Waves in
  Extended New General Relativity   In an extended, new form of general relativity, which is a teleparallel
theory of gravity, we examine the energy-momentum and angular momentum carried
by gravitational wave radiated from Newtonian point masses in a weak-field
approximation. The resulting wave form is identical to the corresponding wave
form in general relativity, which is consistent with previous results in
teleparallel theory. The expression for the dynamical energy-momentum density
is identical to that for the canonical energy-momentum density in general
relativity up to leading order terms on the boundary of a large sphere
including the gravitational source, and the loss of dynamical energy-momentum,
which is the generator of \emph{internal} translations, is the same as that of
the canonical energy-momentum in general relativity. Under certain asymptotic
conditions for a non-dynamical Higgs-type field $\psi^{k}$, the loss of
``spin'' angular momentum, which is the generator of \emph{internal} $SL(2,C)$
transformations, is the same as that of angular momentum in general relativity,
and the losses of canonical energy-momentum and orbital angular momentum, which
constitute the generator of Poincar\'{e} \emph{coordinate} transformations, are
vanishing. The results indicate that our definitions of the dynamical
energy-momentum and angular momentum densities in this extended new general
relativity work well for gravitational wave radiations, and the extended new
general relativity accounts for the Hulse-Taylor measurement of the pulsar
PSR1913+16.
