In this paper we introduce unit bar k-visibility graphs, which are bar kvisibility graphs in which every bar has unit length. We show that almost all families of unit bar k-visibility graphs and unit bar k-visibility graphs are incomparable under set inclusion. In addition, we establish the largest complete graph that is a unit bar k-visibility graph. As well, we present a family of hyperbox vi...

abstract soil moisture measurement and control is a base to employ optimal management methods for reducing water consumption and improvement of the product quality. the main objective of this research was increasing the efficiency of water consumption in a greenhouse condition. this study was carried out in the framework of three treatments of soil potential including irrigation at 40, 60 and 8...

The geometry of the LMC bar is studied using the dereddened mean magnitudes of the red clump stars ( ) I0 from the Optical Gravitational Lensing Experiment II catalog. The value of is found to vary in the east-west I0 direction such that both the east and the west end of the bar are closer to us with respect to the center of the bar. The maximum observed variation has a statistical significance...

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...
