For any knot T transverse to a given contact structure on a 3-manifold, we exhibit a Legendrian two-component link L = L1 t L2 such that T equals the transverse push-off of L1 and contact (+1)surgery on L has the same effect as a Lutz twist along T .

We study the three-dimensional quantum Ising spin glass in a transverse magnetic field following the evolution of the bond probability distribution under Renormalisation Group transformations. The phase diagram (critical temperature Tc vs transverse field Γ) we obtain shows a finite slope near T = 0, in contrast with the infinite slope for the pure case. Our results compare very well with the e...

This paper presents a static aeroelastic model and longitudinal trim model for the analysis of a flexible wing transport aircraft. The static aeroelastic model is built using a structural model based on finite-element modeling and coupled to an aerodynamic model that uses vortex-lattice solution. An automatic geometry generation tool is used to close the loop between the structural and aerodyna...

A diffraction-limited storage ring like NSLS2 requires stringent beam stability. Even with careful design of vacuum component to limit the geometric impedance, due to resistive wall impedance and fast-ion effect, transverse instabilities will happen at low current (~15mA). An active transverse feedback system has been designed to cure the coupled bunch instability. The system will have less tha...

Final state average transverse energy and charged particle multiplicity at the central rapidity unit of central Au-Au collisions at RHIC are studied within a framework of lowest order perturbative QCD and Bjorken's hydrodynamical picture. In particular, effects of initial minijet production and the pdV work during the subsequent evolution of the QGP are investigated. Nuclear shadowing effects a...
