  • The spectra of lifted digraphs 

    Dalfó, Cristina; Fiol, Miguel Angel; Sirán, Jozef (Springer, 2019-01-02)
    We present a method to derive the complete spectrum of the lift Γα of a base digraph Γ , with voltage assignment α on a (finite) group G. The method is based on assigning to Γ a quotient-like matrix whose entries are ...
  • The spectral excess theorem for graphs with few eigenvalues whose distance- 2 or distance-1-or-2 graph is strongly regular 

    Dalfó, Cristina; Fiol, Miguel Angel; Koolen, Jack (Taylor & Francis, 2018-07-13)
    We study regular graphs whose distance-2 graph or distance-1-or-2 graph is strongly regular. We provide a characterization of such graphs Γ (among regular graphs with few distinct eigenvalues) in terms of the spectrum and ...

  • The diameter of cyclic Kautz digraphs 

    Böhmová, Katerina; Dalfó, Cristina; Huemer, Clemens (Faculty of Sciences and Mathematics, University of Nis, Serbia, 2017)
    We present a new kind of digraphs, called cyclic Kautz digraphs CK(d, ɭ), which are subdigraphs of the well-known Kautz digraphs K(d,ɭ). The latter have the smallest diameter among all digraphs with their number of ...
  • On the Randić index of graphs 

    Dalfó, Cristina (Elsevier, 2018-09-11)
    For a given graph G = (V, E), the degree mean rate of an edge uv ∈ E is a half of the quotient between the geometric and arithmetic means of its end-vertex degrees d(u) and d(v). In this note, we derive tight bounds for ...
  • A note on a new general family of deterministic hierarchical networks 

    Dalfó, Cristina; Fiol, Miguel Angel (World Scientific Publishing, 2019)
    It is known that many networks modeling real-life complex systems are small-word (large local clustering and small diameter) and scale-free (power law of the degree distribution), and very often they are also hierarchical. ...
  • Numerical analysis of building envelope with movable phase change materials for heating applications 

    Gracia Cuesta, Alvaro de (MDPI, 2019)
    Latent heat storage materials have been tested by several researchers for decades to be used as passive heating and cooling systems in buildings but their implementation into building components is still stacked as is ...
  • Phenomenological modelling of phase transitions with hysteresis in solid/liquid PCM 

    Barz, Tilman; Emhofer, Johannn; Marx, Klemens; Zsembinszki, Gabriel; Cabeza, Luisa F. (Taylor & Francis, 2019)
    Technical-grade and mixed solid/liquid phase change materials (PCM) typically melt and solidify over a temperature range, sometimes exhibiting thermal hysteresis. Three phenomenological phase transition models are presented ...
  • Cool Roof Impact on Building Energy Need: The Role of Thermal Insulation with Varying Climate Conditions 

    Piselli, Cristina; Pisello, Anna Laura; Saffari Tabalvandani, Mohammad; Gracia Cuesta, Alvaro de; Cotana, Franco; Cabeza, Luisa F. (MDPI, 2019)
    Cool roof effectiveness in improving building thermal-energy performance is affected by different variables. In particular, roof insulation level and climate conditions are key parameters influencing cool roofs benefits ...
  • PPCAS: Implementation of a Probabilistic Pairwise Model for Consistency-Based Multiple Alignment in Apache Spark 

    Lladós Segura, Jordi; Guirado Fernández, Fernando; Cores Prado, Fernando (Springer, 2017)
    Large-scale data processing techniques, currently known as Big-Data, are used to manage the huge amount of data that are generated by sequencers. Although these techniques have significant advantages, few biological ...
  • Comparative Analysis of Energy Demand and CO2 Emissions on Different Typologies of Residential Buildings in Europe 

    Coma Arpón, Julià; Maldonado, José Miguel; Gracia Cuesta, Alvaro de; Gimbernat, Toni; Botargues, Teresa; Cabeza, Luisa F. (MDPI, 2019)
    The building sector accounts for one third of the global energy consumption and it is expected to grow in the next decades. This evidence leads researchers, engineers and architects to develop innovative technologies based ...
  • Anthocyanin tissue bioavailability in animals: possible implications for human health. A systematic review 

    Sandoval-Ramírez, Berner Andrée; Catalan, Ursula; Fernandez-Castillejo, Sara; Rubió Piqué, Laura; Macià i Puig, Ma Alba; Solà, Rosa (American Chemical Society, 2018-10-22)
    Anthocyanins (ACNs) are promising health-enhancing phenolic compounds. We focus on ACN animal tissue bioavailability to provide an evidentiary link between tissue ACNs and their associated health properties. We performed ...
  • A new approach to gross error detection for GPS networks 

    Dalfó, Cristina; Fiol, Miguel Angel (Elsevier, 2019)
    We present a new matrix-based approach to detect and correct gross errors in GPS geodetic control networks. The study is carried out by introducing a new matrix, whose entries are powers of a (real or complex) variable, ...
  • Macromolecular diffusion in crowded media beyond the hard-sphere model 

    Blanco, Pablo M.; Garcés, Josep Lluís; Madurga, Sergio; Mas i Pujadas, Francesc (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 ...
  • Sufficient conditions for a digraph to admit a (1,≤ℓ)-identifying code 

    Balbuena, C.; Dalfó, Cristina; Martínez Barona, B. (University of Zielona Góra, 2019)
    A (1, ≤ `)-identifying code in a digraph D is a subset C of vertices of D such that all distinct subsets of vertices of cardinality at most ` have distinct closed in-neighbourhoods within C. In this paper, we give some ...

    Ochagavía Orbegozo, Helga; Prieto, Paula; Zikhali, Meluleki; Griffiths, Simon; Slafer, Gustavo A. (Nature Publishing Group, 2019-02-22)
    Differences in time to heading that remain after photoperiod and vernalisation requirements have been saturated are classified as earliness per se (Eps) effects. It has been commonly assumed that Eps genes are purely ...

    Pérez-Gianmarco, Thomas I.; Slafer, Gustavo A.; González, Fernanda G. (Oxford University Press, 2018-12-21)
    Lengthening the pre-anthesis period of stem elongation (or late-reproductive phase, LRP) through altering photoperiod sensitivity has been suggested as a potential means to increase the number of fertile florets at anthesis ...
