A symmetry-breaking Hopi bifurcation in an O(2)-symmetric system has eigenvalues of multiplicity two. When the circular symmetry is broken these eigenvalues split into two pairs. The consequences of this splitting in the nonlinear regime are analysed in detail. It is found that the perturbation selects the phase of the standing wave (sw) solutions and that two sw branches, differing in phase by...

OBJECTIVE To determine if there is a significant difference in the infection rates of wounds irrigated with sterile normal saline (SS) versus tap water (TW), before primary wound closure. DESIGN Single centre, prospective, randomised, double-blind controlled trial. Wound irrigation solution type was computer randomised and allocation was done on a sequential basis. SETTING Stanford Universi...

Acute traumatic wounds occur when the body is subjected to a force that exceeds the strength of the skin or underlying tissue (Whiteside and Moorehead, 1993), and can be caused by a variety of mechanisms (Holt, 2000). Healing of acute wounds involves a complex, wellorchestrated series of events, resulting in a healed wound in a timely and orderly manner (Enoch and Leaper, 2005). All acute traum...

We present theoretical results with soft-gluon corrections for two separate processes: (1) the production of a single top quark in association $W$ boson Standard Model; and (2) heavy $Z'$ new physics models or without anomalous couplings. show that higher-order from emission are dominant wide range collider energies. Results shown total cross sections top-quark transverse-momentum rapidity dist...
