BAR domains are protein modules that bind to membranes and promote membrane curvature. One type of BAR domain, the N-BAR domain, contains an additional N-terminal amphipathic helix, which contributes to membrane-binding and bending activities. The only known N-BAR-domain proteins in the budding yeast Saccharomyces cerevisiae, Rvs161 and Rvs167, are required for endocytosis. We have explored the...

Perhaps the most common method of depicting data, in both scientific communication and popular media, is the bar graph. Bar graphs often depict measures of central tendency, but they do so asymmetrically: A mean, for example, is depicted not by a point, but by the edge of a bar that originates from a single axis. Here we show that this graphical asymmetry gives rise to a corresponding cognitive...

The symmetry of floating drops is considered. Under conditions that the free boundary is flat it is shown that all three component interfaces are symmetric about a vertical line.

AIMS We investigated the impact of arterial injury on neointimal hyperplasia following implantation of drug-eluting stents (DES). METHODS AND RESULTS A total of 196 patients with 223 segments (sirolimus-eluting stents [SES]: 104, paclitaxel-eluting stents [PES]: 119) underwent intravascular ultrasound eight months after DES implantation. Arterial injury was defined as the balloon-to-artery ra...

Vegetation was added to a fully-developed sandy point bar in the meander of a 5 constructed stream. Significant changes in the flow structure and bed topography were observed. 6 As expected, the addition of vegetative resistance decreased the depth-averaged streamwise 7 velocity over the bar and increased it in the open region. In addition, the secondary circulation 8 increased in strength, but...

Here, we show that BarH1 and BarH2, a pair of Bar homeobox genes, play essential roles in the formation and specification of the distal leg segments of Drosophila. In early third instar, juxtaposition of Bar-positive and Bar-negative tissues causes central folding that may separate future tarsal segments 2 from 3, while juxtaposition of tissues differentially expressing Bar homeobox genes at la...

A bar 1-visibility drawing of a graph G is a drawing of G where each vertex is drawn as a horizontal line segment called a bar, each edge is drawn as a vertical line segment where the vertical line segment representing an edge must connect the horizontal line segments representing the end vertices and a vertical line segment corresponding to an edge intersects at most one bar which is not an en...
