Quality assurance implementation plan for spent nuclear fuel characterization
A plan was prepared to implement the Quality Assurance requirements of the Office of Civilian Radioactive Waste Management RW-0333P to the Spent Nuclear Fuel Characterization activities. The plan was based on an evaluation of the current characterization activities against the RW-0333P requirements
Treatment for hepatorenal syndrome in people with decompensated liver cirrhosis: a network meta-analysis
This is a protocol for a Cochrane Review (Intervention). The objectives are as follows:
To compare the benefits and harms of different treatments of hepatorenal syndrome in people with decompensated liver cirrhosis
Comments on Condensates in Non-Supersymmetric Orbifold Field Theories
Non-supersymmetric orbifolds of N=1 super Yang-Mills theories are conjectured
to inherit properties from their supersymmetric parent. We examine this
conjecture by compactifying the Z_2 orbifold theories on a spatial circle of
radius R. We point out that when the orbifold theory lies in the weakly coupled
vacuum of its parent, fractional instantons do give rise to the conjectured
condensate of bi-fundamental fermions. Unfortunately, we show that quantum
effects render this vacuum unstable through the generation of twisted
operators. In the true vacuum state, no fermion condensate forms. Thus, in
contrast to super Yang-Mills, the compactified orbifold theory undergoes a
chiral phase transition as R is varied.Comment: 10 Pages. Added clarifying comments, computational steps and a nice

Rapid X-ray Variability of Seyfert 1 Galaxies
The rapid and seemingly random fluctuations in X-ray luminosity of Seyfert
galaxies provided early support for the standard model in which Seyferts are
powered by a supermassive black hole fed from an accretion disc. However, since
EXOSAT there has been little opportunity to advance our understanding of the
most rapid X-ray variability. Observations with XMM-Newton have changed this.
We discuss some recent results obtained from XMM-Newton observations of Seyfert
1 galaxies. Particular attention will be given to the remarkable similarity
found between the timing properties of Seyferts and black hole X-ray binaries,
including the power spectrum and the cross spectrum (time delays and
coherence), and their implications for the physical processes at work in
Seyferts.Comment: To appear in From X-ray Binaries to Quasars: Black Hole Accretion on

Mixed configuration-interaction and many-body perturbation theory calculations of energies and oscillator strengths of J=1 odd states of neon
Ab-initio theory is developed for energies of J=1 particle-hole states of
neutral neon and for oscillator strengths of transitions from such states to
the J=0 ground state. Hole energies of low-Z neonlike ions are evaluated.Comment: 5 pages, 1 figure, 4 table
Magnetic Resonance Imaging of Plantar Plate Rupture
Degenerative plantar plate failure is an under-recognized cause of lesser metatarsalgia. We performed magnetic resonance imaging (MRI) with a small receiver coil in 13 patients in whom plantar plate ruptures of the second or third metatarsophalangeal joint were clinically suspected. In eight patients, MRI showed focal hyperintensity in the plantar plate that was interpreted as a rupture of the plate. Ruptures were confirmed in all five patients who underwent an operative procedure to treat the unstable, painful metatarsophalangeal joint. MRI is a noninvasive technique that can visualize plantar plate abnormalities and aid the clinical evaluation of problematic lesser metatarsalgia
