It is suggested that the persistent X-ray emission from the soft γ-ray repeaters is the thermal radiation of neutron stars which is enhanced by a factor of 10 or more due to the effect of a very strong magnetic field on the thermal structure of the neutron star envelope. For the thermal luminosity to be consistent with the persistent X-ray luminosity, the field strength at the neutron star surf...

STUDY DESIGN Soft tissue-related injuries to the cervical spine structures were produced by use of intact entire human cadavers undergoing rear-end impacts. Radiography, computed tomography, and cryomicrotomy techniques were used to evaluate the injury. OBJECTIVES To replicate soft tissue injuries resulting from single input of whiplash acceleration to whole human cadavers simulating vehicula...

We apply our Yennie-Frautschi-Suura exponentiated cross section formulas for the parton processes q + (¯ q)′ → q ′′ + (¯ q)′′′ + n(G) to the process q + ¯ q → t + ¯ t + n(G) at FNAL energies, where G is a QCD gluon. We use semi-analytical methods to compute the ratio r exp = σ exp /σ B , where σ exp is our soft gluon YFS exponentiated cross section and σ B is the Born cross section. For m t = 0...

When are athermal soft-sphere packings jammed? Any experimentally relevant definition must, at the very least, require a jammed packing to resist shear. We demonstrate that widely used (numerical) protocols, in which particles are compressed together, can and do produce packings that are unstable to shear-and that the probability of generating such packings reaches one near jamming. We introduc...

The spectrum of complex PT-symmetric potential, V (x) = igx, is known to be null. We enclose this potential in a hard-box: V (|x| ≥ 1) = ∞ and in a softbox: V (|x| ≥ 1) = 0. In the former case, we find real discrete spectrum and the exceptional points of the potential. The asymptotic eigenvalues behave as En ∼ n. The solvable purely imaginary PT-symmetric potentials vanishing asymptotically kno...

A 12-YEAR-OLD male child had a history of swelling in the left knee joint since age 4 years. There was no pain or other constitutional symptoms. On physical examination the swelling was soft and boggy. There was no tenderness and the movements were not painful or restricted. Results of routine blood investigations were within normal limits. Aspiration of the knee joint did not reveal any fluid....

Group C and G streptococci, classified as Streptococcus dysgalactiae subsp. equisimilis(SDSE), are an unusual cause of sepsis in pediatric patients. SDSE have a similar pathogenicity to Streptococcus pyogenes, and can cause pharyngitis and skin and soft-tissue infections. Rarely, these organisms cause invasive disease including osteoarticular infections, bacteremia, and meningitis. In this repo...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014205021 DESCRIPTION Ainhum (dactylolysis spontanea) is an idiopathic condition that involves a ‘band-like’ soft tissue constriction of a digit. This pathology often presents bilaterally with the greatest prevalence on the fifth digit. Dark-skinned individuals of ...
