Small cutsets in arc-transitive digraphs of prime degree
(Elsevier, 2013)We give an upper bound for the size of non-trivial sets that have small boundary in a family of arc-transitive digraphs. We state the exact size for these sets in case of prime degree. We also give a lower bound for the ... -
On Vosperian and Superconnected Vertex-Transitive Digraphs
(Springer, 2013)We investigate the structure of a digraph having a transitive automorphism group where every cutset of minimal cardinality consists of all successors or all predecessors of some vertex. We give a complete characterization ... -
Unraveling the role of light and biotic interactions on seedling performance of four Pyrenean species along environmental gradients
(Elsevier, 2013)The predicted upward displacement of forest species due to climate warming is expected to be modulated by a medley of abiotic and biotic factors acting at microsite level. Species-specific differences in plant responses ... -
Understory light predictions in mixed conifer mountain forests: Role of aspect-induced variation in crown geometry and openness
(Elsevier, 2012)Predicting light availability in forest understory is a key step in the modeling of forest dynamics. Aspect is often the main source of environmental variation in mountain forests, and so aspect-induced differences in crown ... -
Sustainability and social justice dimension indicators for applied renewable energy research: A responsible approach proposal
(Elsevier, 2019)Aspects of sustainability and social justice deserve special attention in the research and innovation landscape in Europe. In this vein, the inclusion of innovative research and innovation policies, such as Responsible ... -
A new labeling construction from the ⊗h-product
(Elsevier, 2017)The -product that is referred in the title was introduced in 2008 as a generalization of the Kronecker product of digraphs. Many relations among labelings have been obtained since then, always using as a second factor a ... -
Distance labelings: a generalization of Langford sequences
(University of Primorska, 2017)A Langford sequence of order m and defect d can be identified with a labeling of the vertices of a path of order 2m in which each label from d up to d + m − 1 appears twice and in which the vertices that have been labeled ... -
Rainbow eulerian multidigraphs and the product of cycles
(DMTCS, 2016)An arc colored eulerian multidigraph with $l$ colors is rainbow eulerian if there is an eulerian circuit in which a sequence of $l$ colors repeats. The digraph product that refers the title was introduced by Figueroa-Centeno ... -
(Di)graph products, labelings and related results
(Elsevier, 2017)Gallian's survey shows that there is a big variety of labelings of graphs. By means of (di)graphs products we can establish strong relations among some of them. Moreover, due to the freedom of one of the factors, we can ... -
Langford sequences and a product of digraphs
(Elsevier, 2016)Skolem and Langford sequences and their many generalizations have applications in numerous areas. The -product is a generalization of the direct product of digraphs. In this paper we use the -product and super edge-magic ... -
Connectivity and other invariants of generalized products of graphs
(Springer, 2015)Figueroa-Centeno et al. [4] introduced the following product of digraphs let D be a digraph and let Γ be a family of digraphs such that V (F) = V for every F∈Γ . Consider any function h:E(D)→Γ . Then the product D⊗hΓ is ... -
Genetic characterization of a reciprocal translocation present in a widely grown barley variety
(Springer Netherlands, 2012-01-28)Artificially induced translocation stocks have been used to physically map the barley genome; however, natural translocations are extremely uncommon in cultivated genotypes. Albacete is a barley variety widely grown in ... -
Fertilización con purín porcino: impacto sobre las lombrices de tierra en agricultura de secano
(Facultad de Ciencias Agrarias, Universidad Nacional de Asunción, 2019-06-01)Earthworms play an important role in the maintenance of soil ecosystem services. Their presence and activity are influenced by agricultural practices as fertilization. The objective of this research was to identify earthworm ... -
The Contribution of surrounding margins in the promotion of natural enemies in mediterranean apple orchards
(MDPI, 2019-05-23)(1) Habitat management can enhance beneficial arthropod populations and provide ecosystem services such as biological control. However, the implementation of ecological infrastructures inside orchards has a number of practical ... -
La localización espacial de los atractivos turísticos de un área metropolitana: diferencias entre material turístico institucional, guías turísticas y contenidos generados por los usuarios
(Universitat Autònoma de Barcelona: Departament de Geografia, 2019-06-01)El estudio se centra en las diferencias existentes en la distribución de los atractivos turísticos en función de tres fuentes: el material turístico institucional, las guías turísticas y los contenidos generados por los ... -
Frecuency and levels of mycotoxins in beer from the Mexican market and exposure estimate for deoxynivalenol mycotoxins
(Springer Berlin Heidelberg, 2019-04-26)The aim of the present study was to evaluate the occurrence of 23 mycotoxins in beer purchased in Mexico and to assess 14 two exposure scenarios in the Mexican population through beer consumption. Multi-mycotoxin analysis ... -
Strategies to reduce microbial risk and improve quality of fresh and processed strawberries: A review
(Elsevier, 2019-03)Strawberries are one of the most important fruits in the Mediterranean diet and have been widely investigatedfor their nutritional and nutraceutical properties. Concern about the safety of fresh and processed strawberrieshas ... -
Automatic wheat ear counting using thermal imagery
(MDPI, 2019-03-28)Ear density is one of the most important agronomical yield components in wheat. Ear counting is time-consuming and tedious as it is most often conducted manually in field conditions. Moreover, different sampling techniques ... -
Macromolecular diffusion in crowded media beyond the hard-sphere model
(Royal Society of Chemistry, 2018-03-20)The effect of macromolecular crowding on diffusion beyond the hard-core sphere model is studied. A new coarse-grained model is presented, the Chain Entanglement Softened Potential (CESP) model, which takes into account the ... -
