Fluctuating pulled fronts & Pomerons

I give a physical discussion of the influence of particle number fluctuations on the high energy evolution in QCD. I emphasize the event–by–event description and the correspondence with the problem of ‘fluctuating pulled fronts’ in statistical physics. I show that the correlations generated by fluctuations reduce the phase–space for BFKL evolution up to saturation. Because of that, the evolutio...

Speed of pulled fronts with a cutoff.

We study the effect of a small cutoff epsilon on the velocity of a pulled front in one dimension by means of a variational principle. We obtain a lower bound on the speed dependent on the cutoff, for which the two leading order terms correspond to the Brunet-Derrida expression. To do so we cast a known variational principle for the speed of propagation of fronts in different variables which mak...

Ultrasonography of pulled elbow.

We used ultrasonography in ten children with pulled elbow to compare measurements of the radiocapitellar distance (RCD) on the affected and the unaffected sides. Similar measurements were made in a group of ten age-matched normal children. The mean RCD in pronation of the affected and normal sides in the patients with pulled elbows was 7.2 mm +/- 0.7 and 3.8 mm +/- 0.5, respectively (p < 0.0001...

Why hamstring eccentrics are hamstring essentials.

There is no dispute that acute hamstring injury is a major sports injury, 1–6 particularly in football codes 2 3 5 6 and other sports that demand high-speed running. 1 The purpose of this editorial is to provide the reader with evidence-based tips for optimising hamstring injury prevention. Early return to sport (≤3 weeks) is often proposed for hamstring injuries, 7 even though basic research c...
