P Cygni is a prototype for understanding mass loss from massive stars. This textbook star is known first of all because of two great eruptions in the 17th century. In the first half of this century it has given its name to a class of stars which are characterized by spectral lines consisting of nearly undisplaced emissions accompanied by a blue-displaced absorption component. This characteristi...

Simulations of radio emission from extensive air showers we have published so far were performed with a Monte Carlo code using analytical parametrisations to describe the spatial, temporal, energy and angular particle distributions in the air shower. A new version of our simulation code, which replaces these parametrisations with precise, multi-dimensional histograms derived from per-shower COR...

Ga-NMR local susceptibility of the kagomé-based magnet SrCr 9p Ga 12−9p O 19. A high temperature study. Abstract We report a high-T Ga-NMR study in the kagomé-based antiferromagnetic compound SrCr 9p Ga 12−9p O 19 (.81 ≤ p ≤ .96), and present a refined mean-field analysis of the local NMR susceptibility of Cr frustrated moments. We find that the intralayer kagomé coupling is J = 86(6) K, and th...

We review some theoretical and experimental issues in unparticle physics, focusing mainly on collider signatures.

Experiments are planned to improve the sensitivity of μ − e conversion from the current ∼ 10 to ∼ 10 − 10. If the muon (bound to the nucleus) could be polarised, a spin asymmetry of the final state electron is sensitive to CP violating phases on lepton flavour violating operators. This is similar to extracting phases from asymmetries in the final state spin and phase space distributions of μ → ...

background: inflammatory bowel disease, an autoimmune disease, has two clinical manifestations including crohn’s disease and ulcerative colitis (uc). il-17 has been the target of intensive research in autoimmune diseases. the influence of toll like receptor 4 (tlr-4) gene polymorphisms on il-17 production has also been revealed in uc patients and tissue inflammation in mice. objectives: to inve...
