The disposable QED saliva alcohol test provides a very simple, fast, and reliable means for quantitative onsite alcohol detection. The purpose of this study was to determine if the QED test would be a useful tool for the determination of postmortem ethanol levels in cases where a rapid result was needed. QED results were compared with ethanol levels determined by headspace GC analysis. Both sal...

We calculate all the four-photon helicity amplitudes at the one-loop level in a massive theory using multiplecut methods. The amplitudes are derived in scalar QED, QED and QED theories. We will see the origin of rational terms. We extend the calculation to the simplest six-photon helicity amplitude where all photons have the same helicity. version June 28, 2009

After a brief review of higher-order QED eeects, a survey is made of novel aspects of QED with emphasis on recent experimental results in strong-eld QED: nonlinear Compton scattering and multiphoton pair creation by light. Quantum Electrodynamics (QED) describes the interactions between charged particles that are mediated by quanta (photons) of the electromagnetic eld. The simplest QED processe...

It is shown that a photon with a specific frequency can be identified with the Dirac magnetic monopole. When a Dirac-Wilson line forms a Dirac-Wilson loop, it is a photon. This loop model of photon is exactly solvable. From the winding numbers of this loop-form of photon, we derive the quantization properties of energy and electric charge. A new QED theory is presented that is free of ultraviol...

We report the result of our calculation of the complete tenth-order QED terms of the muon g-2. Our result is a(μ)((10))=753.29 (1.04) in units of (α/π)(5), which is about 4.5 s.d. larger than the leading-logarithmic estimate 663(20). We also improve the precision of the eighth-order QED term of a(μ), obtaining a(μ)((8))=130.8794 (63) in units of (α/π)(4). The new QED contribution is a(μ)(QED)=1...

We present Symbolic Quick Error Detection (Symbolic QED), a structured approach for logic bug detection and localization which can be used both during pre-silicon design verification as well as post-silicon validation and debug. This new methodology leverages prior work on Quick Error Detection (QED) which has been demonstrated to drastically reduce the latency, in terms of the number of clock ...

Lavelle-McMullan symmetry of QED is examined at classical and quantum levels. It is shown that Lavelle-McMullan symmetry does not give any new non-trivial information in QED by examining the Ward-Takahashi identities. Being inspired by the examination of Ward-Takahashi identity, we construct the generalized non-local and non-covariant symmetries of QED.
