Relative intensity noise spectra of weakly index guided VCSELs in a multi{transverse mode regime are analyzed by using a model that takes into account all the transverse modes supported by the waveguide. Several resonance peaks are obtained in the noise spectra that correspond to the relaxation oscillation frequencies of the transverse modes. In is shown that for low spatially overlapping trans...

The mean transverse momentum in high energy nuclear collisions is studied. The formation of a Color Glass Condensate results in an increase of the square of the mean transverse momentum with the charged multiplicity per unit rapidity and unit transverse area. This prediction is in agreement with the presently available data, in particular with the heavy-ion data, lending support to the notion t...

We report a case of spontaneous transverse colon volvulus in a young healthy woman. It constitutes an unusual case since it occurred in a young healthy woman with a subacute onset and no aetiological factor has been found. Its diagnosis is still challenging. Prompt recognition with emergency intervention constitutes the key to successful outcome.

We consider some flat space theories for spin 2 gravitons, with less invariance than full diffeomorphisms. For the massless case, classical stability and absence of ghosts require invariance under transverse diffeomorphisms (TDiff), hμν 7→ hμν + 2∂(νξμ), with ∂μξ μ = 0. Generic TDiff invariant theories contain a propagating scalar, which disappears if the symmetry is enhanced in one of two ways...

Acute transverse myelitis (ATM) is an inflammatory demyelinating disorder that affects the spinal cord focally resulting in motor sensory and autonomic dysfunction. Establishing the diagnosis of ATM is not as difficult as determining the possible etiology. There is a difference in the perception of ATM seen in the West as compared to developing countries. In the West multiple sclerosis (MS) is ...

Machine studies have been conducted in the SPS to better characterise the transverse instabilities observed on the LHC beam by the beam induced electron cloud. Most of the observations have been performed at injection energy. Different beam configurations have been considered as a function of their availability from the injectors. The results of these observations (bunch centroid motion, head-t...

We study the transverse momentum distribution for a pair of heavy quarks produced in hadron-hadron interactions. Predictions for the large transverse momentum region are based on exact order αs QCD perturbation theory. For the small transverse momentum region, we use techniques for all orders resummation of leading logarithmic contributions associated with initial state soft gluon radiation. Th...
