Branch-and-price algorithms for the graph coloring problem use an exponentially-sized independent set based integer programming formulation to produce usually tight lower bounds to enable more aggressive pruning in the branch-and-bound tree. One major problem inherent to any branch-and-price scheme for graph coloring is that in order to avoid destroying the pricing problem structure during colu...

To study the impact of iron nanoparticles foliar application on mitigating the effects of drought stress on yield, yield components and  oil percentage of Goldasht spring safflower cultivar, an experiment was carried out in 2012 in the Agricultural Research Farm Station of Islamic Azad University, Roudehen branch as split plot in a completely randomized blocks design with three replications. In...

The leaf of the jaborandi (Pilocarpus microphyllus) is part plant economic interest, from which pilocarpine extracted, therefore, production main variable that determines productivity this species. Pilocarpus can be managed during its development phase. Thus, objective present study was to evaluate branch regeneration submitted two types cutting/pruning and different cropping systems. Prunings ...

Water stress and soil nutrients affect the growth of medicinal herbs as well as the quantity and quality of their essential oils. The effect of drought stress and different fertilizers on yield and morphological traits of Ajowan was studied in a split-plot experiment on the basis of a Randomized Complete Block Design with three replications in Qaen, Iran. The main plot was devoted to irrigation...

The species Gracilariopsis persica was first described by Bellorin et al. (2008). G. persica grows from late September to July and shows high growth rate from January to May in the Persian Gulf. Tissue growth and branch induction of red seaweed, Gracilariopsis persica from the Persian Gulf investigated under various culture levels of temperature, light intensity, photoperiod, salinity, initial ...

There is a frequent need to compute medial shape representations of each of a group of structures, e.g. for use in a medical study of anatomical shapes. We present a novel approach to skeletonization that leverages information provided from such a group. We augment the traditional medial axis transform with an additional coordinate stored at each medial locus, indicating the confidence that the...
