Zonal Jets as Transport Barriers in Planetary Atmospheres [PDF]
The connection between transport barriers and potential vorticity (PV) barriers in PV-conserving flows is investigated with a focus on zonal jets in planetary atmospheres. A perturbed PV-staircase model is used to illustrate important concepts. This flow

Conceptual barriers to understanding physical barriers [PDF]
The members of the large family of claudin proteins regulate ion and water flux across the tight junction. Many claudins, e.g. claudins 2 and 15, accomplish this by forming size- and charge-selective paracellular channels. Claudins also appear to be essential for genesis of tight junction strands and recruitment of other proteins to these sites.

Surmounting Oscillating Barriers
Thermally activated escape over a potential barrier in the presence of periodic driving is considered. By means of novel time-dependent path-integral methods we derive asymptotically exact weak-noise expressions for both the instantaneous and the time ...

Barriers to participation in vocational orientation programmes among prisoners [PDF]
This study investigates the barriers to prisoners’ participation in vocational education, as well as the predictors of different types of barriers. Survey data derived from a project in a remand prison in Belgium (N=468) provided the empirical evidence ...

Lattice QCD without topology barriers [PDF]
As the continuum limit is approached, lattice QCD simulations tend to get trapped in the topological charge sectors of field space and may consequently give biased results in practice. We propose to bypass this problem by imposing open (Neumann) boundary

A new type of ultrasonic water alleviates constipation with favorable safety
IntroductionUltrasonic water (UW) is a novel category of functional drinking water. This study aimed to investigate its laxative efficacy and underlying mechanisms using a constipation model in SD rats, while also conducting a comprehensive safety ...
