We compute the tunneling probability from the symmetric phase to the true vacuum, in the first order electroweak phase transition of the MSSM, and the corresponding Higgs profiles along the bubble wall. We use the resummed two-loop temperature-dependent effective potential, and pay particular attention to the light stop scenario, where the phase transition can be sufficiently strongly first ord...

The dividing wall column is experiencing a growing interest in industry. The concern about difficult controllability vanishes further and this leads to growing demand of approved guidelines for the design which is indeed time consuming if no expert knowledge is available. In this contribution the design task of a dividing wall column is treated as multi objective optimisation. Backbone of this ...

We study stochastic control problems in the presence of hard wall constraints. Walls are incorporated in the dynamics of the agent by restricting its domain and hence perturbing the noise process close to the walls. A novel penalty term is introduced for bouncing off a wall. To efficiently search for a good policy we propose the “hallucination expectation maximization” algorithm which iterative...

OBJECTIVE The initial site of myocardial infarction (MI) may influence the prevalence of ventricular late potentials (VLP), high-frequency signals, due to the time course of ventricular activation. The prevalence of VLP in a period of more than 2 years after acute MI was assessed focusing on the initially injured wall. METHODS The prevalence of VLP in a late phase after MI (median of 924 days...

Up to now, the BAUER Trench Cutter Cut-Off Wall (COW) technology has been developed for more than 20 years for use on large dams. The special task of a COW is to mitigate seepage and therefore COW's are utilized either on dam rehabilitation projects or on new dams as well. Seepage mitigation, for the long-term stability and the safety of dykes and dams, is a major issue to the designers. Cut-of...

Submitted for the DPP09 Meeting of The American Physical Society Design of a Linear-Quadratic-Gaussian controller for resistive wall mode stabilization in NSTX1 OKSANA KATSURO-HOPKINS, S.A. SABBAGH, J.M. BIALEK, Columbia University, S.P. GERHARDT, PPPL — Stabilization of the resistive wall mode (RWM) in the NSTX is important to achieve and sustain high-beta plasmas. State-space control algorith...

Background and study aims  Endoscopic drainage of walled-off pancreatic necrosis (WOPN) is feasible when contact with the gastric or duodenal wall is present; when WOPN cannot be accessed endoscopically, a percutaneous approach can be considered. Percutaneous use of esophageal self-expandable metal stents (SEMS) to establish access to a WOPN cavity was evaluated.
