  • Current trends in the social-economic integration of Gypsy migrants in the European Union 

    Marushiakova-Popova, Elena Andreevna; Popov, Veselin (2017-08-08) - Journal article
    Gypsies are not an isolated group, they have a multifaceted identity and national individuality. In order to identify the nature and determinants of Roma migrations, they should be given attention as an ethnically specific ...
  • Correct composition of dephased behavioural models 

    Bowles, Juliana Kuster Filipe; Caminati, Marco Bright (Springer, 2017) - Conference item
    Scenarios of execution are commonly used to specify partial behaviour and interactions between different objects and components in a system. To avoid overall inconsistency in specifications, various automated methods have ...
  • Evidence suggests vocal production learning in a cross-fostered Risso’s dolphin (Grampus griseus) 

    Favaro, Livio; Neves, Silvana; Furlati, Stefano; Pessani, Daniela; Martin, Vidal; Janik, Vincent M. (2016-07) - Journal article
    Vocal learning is a rare skill in mammals, and we have limited information about the contexts in which they use it. Previous studies suggested that cetaceans in general are skilled at imitating sounds, but only few species ...
  • Come dine with me : food-associated social signalling in wild bottlenose dolphins (Tursiops truncatus) 

    King, Stephanie Laura; Janik, Vincent M. (2015-07) - Journal article
    Food-related signalling is widespread in the animal kingdom with some food-associated vocalizations considered functionally referential. Food calls can, however, vary greatly in the type of information they convey. Thus, ...
  • Fish pool their experience to solve problems collectively 

    Webster, Michael Munro; Whalen, Andrew Carl Zanton; Laland, Kevin Neville (2017-04-18) - Journal article
    Access to information is a key advantage of grouping. While experienced animals can lead others to solve problems, less is known about whether partially informed individuals can pool experiences to overcome challenges ...
  • Post-synthesis stabilization of germanosilicate zeolites ITH, IWW, and UTL by substitution of Ge for Al 

    Shamzhy, Mariya V.; Eliašová, Pavla; Vitvarová, Dana; Opanasenko, Maksym V.; Firth, Daniel S.; Morris, Russell E. (2016-11-21) - Journal article
    Germanosilicate zeolites often suffer from low hydrothermal stability due to the high content of Ge. Herein, we investigated the post-synthesis introduction of Al accompanied by stabilization of selected germanosilicates ...
  • Parallel algorithms for computing finite semigroups 

    Jonusas, Julius; Mitchell, J. D.; Pfeiffer, M. (2017-06-19) - Journal article
    In this paper, we present two algorithms based on the Froidure-Pin Algorithm for computing a finite semigroup. If U is any semigroup, and A be a subset of U, then we denote by ⟨A⟩ the least subsemigroup of U containing A.  ...
  • Phosphorus-sulfur heterocycles incorporating an O-P(S)-O or O-P(S)-S-S-P(S)-O scaffold : one-pot synthesis and crystal structure study 

    Hua, Guoxiong; Davidson, Kate; Cordes, David B.; Du, Junyi; Slawin, Alexandra M. Z.; Woollins, J. Derek (2017-10-10) - Journal article
    A new one-pot preparative route was developed to synthesize novel organophosphorus sulfur heterocycles via the reaction of the four-membered ring thionation reagent [2,4-diferrocenyl 1,3,2,4-diathiadiphosphetane 2,4-disulfide ...
  • Zircon geochronology reveals polyphase magmatism and crustal anatexis in the Buchan Block, NE Scotland : implications for the Grampian Orogeny
