      A new general family of mixed graphs is presented, which generalizes both the pancake graphs and the cycle prefix digraphs. The obtained graphs are vertex transitive and, for some values of the parameters, they constitute ...
    • 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. ...
    • A novel carotenoid, 4-keto-a-carotene, as an unexpected by-product during genetic engineering of carotenogenesis in rice callus 

      Breitenbach, Jürgen; Bai, Chao; Rivera Vélez, Sol Maiam; Canela i Garayoa, Ramon; Capell Capell, Teresa; Christou, Paul; Zhu, Changfu; Sandmann, Gerhard (Elsevier, 2014)
      Rice endosperm is devoid of carotenoids because the initial biosynthetic steps are absent. The early carotenogenesis reactions were constituted through co-transformation of endosperm-derived rice callus with phytoene ...
    • A question of balance: achieving appropriate nutrient levels in biofortified staple crops 

      Sanahuja Solsona, Georgina; Farré Martinez, Gemma; Berman Quintana, Judit; Zorrilla López, Uxue; Twyman, Richard M.; Capell Capell, Teresa; Christou, Paul; Zhu, Changfu (Cambridge University Press, 2013)
      The biofortification of staple crops with vitamins is an attractive strategy to increase the nutritional quality of human food, particularly in areas where the population subsists on a cereal-based diet. Unlike other ...
