A bstract We study scattering amplitudes in the shadow conformal primary basis, which satisfies same defining properties as original basis and has many advantages over it. The celestial exhibit locality manifestly on sphere, behave like correlation functions field theory under operator product expansion (OPE) limit. OPE limits for three-point amplitude, general 2 ? n ? from a certain class of F...

Waveforms play an important role in the detection of gravitational-wave events from binary mergers. A useful formalism to deal with two-body problem gravity is use quantum scattering amplitudes a particular expansion and extract classical observables. As extension previous work, authors incorporate massless bosonic particles initial states into show that limit they emerge coherent due their nat...

several previous studies of adults have reported that the amplitudes of the sural and superficial radial nerve (sn and srn) action potentials are larger with antidromic than with orthodromic recordings. however, this difference has not been documented in children. this study evaluated the amplitudes of sn and srn sensory nerve action potentials (snaps), obtained with antidromic and orthodromic ...
