High-resolution two and three-dimensional numerical experiments are used to study the manner in which advection of potential vorticity (PV) by frontal instabilities growing out of an initially symmetrically unstable flow or forced by destabilizing wind-forcing constrains the extreme minima in the PV to values near zero. The instabilities act as a PV pump, upwelling high PV water from the pycnoc...

A novel configuration of pervaporation and vapor permeation processes is introduced. In the suggested process the driving force for permeation is enabled by the absorption of the permeate vapors using a suitable solvent with a low vapor pressure. Thus, the refrigeration needed for condensing the permeate under vacuum can be overcome and cost savings can be achieved. Moreover, very low vacuum pr...

AIMS Prior reports using pacing manoeuvres, demonstrated an up to 42% prevalence of residual pulmonary vein to left atrium (PV-LA) exit conduction after apparent LA-PV entry block. We aimed to determine in a two-centre study the prevalence of residual PV-LA exit conduction in the presence of unambiguously proven entry block and without pacing manoeuvres. METHODS AND RESULTS Of 378 patients, 1...

Human adenoviruses (Ads) replicate and assemble particles in the nucleus. They organize a linear double-strand DNA genome into a condensed core with about 180 nucleosomes, by the viral proteins VII (pVII), pX, and pV attaching the DNA to the capsid. Using reverse genetics, we generated a novel, nonconditionally replicating Ad reporter by inserting green fluorescent protein (GFP) at the amino te...
