BACKGROUND AND AIMS Plant genotypic mixtures have the potential to increase yield stability in variable, often unpredictable environments, yet knowledge of the specific mechanisms underlying enhanced yield stability remains limited. Field studies are constrained by environmental conditions which cannot be fully controlled and thus reproduced. A suitable model system would allow reproducible exp...

[1] ABSTRACT The International Aerial Robotics Competition (IARC) is designed for colleges and universities to compete in the design and construction of an autonomous aerial vehicle. Pima Community College is being represented by the Unmanned Aerial Vehicle (UAV) Club. The UAV Club has designed a primary vehicle and a drop vehicle that will be used in the competition. They were designed with au...

The date that yellow-bellied marmots (Marmota flaviventris) emerge at a site in Colorado has been used as evidence that climate is affecting hibernating species. Over 6 springs, and at 16 marmot groups, the date of 1st emergence of males, females, and the group as a whole was recorded. Emergence date of males was a function of the number of males in a group (a metric of reproductive competition...

We investigate the implications of collective and individual producer responsibility (CPR and IPR, respectively) models of product take-back laws for e-waste on manufacturers’ design for product recovery (DfR) choices and profits, and on consumer surplus in the presence of product competition. We show that IPR offers superior DfR incentives as compared to CPR, and provides a level competitive g...

This book explores the realm of international political life that occupies a middle ground between the anarchy characteristic of international politics and the order characteristic of national politics. This is the realm of international society. As a starting point, this book shares the realist assumption that states reside in a Hobbesian international system whose default equilibrium is one o...

With this paper, we apply for the RocKIn@Work competition with the smARTLab@work team that has won the 2014 RoboCup@Work competition. smARTLab (swarms, multiagent, and robot technologies and learning lab) is a robotics research lab that is part of the Agent ART group at the computer science department of the University of Liverpool. This team has won the competition for the second year in a row...

Coloration and figural properties of neon color spreading and the watercolor illusion are studied using phenomenal and psychophysical observations. Coloration properties of both effects can be reduced to a common limiting condition, a nearby color transition called the two-dot limiting case, which clarifies their perceptual similarities and dissimilarities. The results are explained by the FACA...

Knowledge about the phylogeny and ecology of communities along environmental gradients helps to disentangle the role of competition-driven processes and environmental filtering for community assembly. In this study, we evaluated patterns in species richness, phylogenetic structure and life-history traits of bee communities along altitudinal gradients in the Alps, Germany. We found a linear decl...

We propose a new technique to extract a pulmonary nodule from helical thoracic CT scans and estimate its diameter. The technique is based on a novel segmentation, or label-assignment, framework called competition-diffusion (CD), combined with robust ellipsoid fitting (EF). The competition force defined by replicator equations draws one dominant label at each voxel, and the diffusion force encou...

The formal equivalence between the quartetting picture and symmetry restored BCS is established for ground state correlations induced by general isovector-isoscalar pairing interaction. Multiple structures compatible with particle number isospin symmetries are evaluated. competition of isovector isoscalar discussed $N=Z$ nuclei above $^{100}$Sn.
