  • A dynamical definition of f.g. virtually free groups 

    Bennett, Daniel; Bleak, Collin (2016-02) - Journal article
    We show that the class of finitely generated virtually free groups is precisely the class of demonstrable subgroups for R. Thompson's group V . The class of demonstrable groups for V consists of all groups which can embed ...
  • PAEAN : portable and scalable runtime support for parallel Haskell dialects 

    Berthold, Jost; Loidl, Hans-Wolfgang; Hammond, Kevin (2016) - Journal article
    Over time, several competing approaches to parallel Haskell programming have emerged. Different approaches support parallelism at various different scales, ranging from small multicores to massively parallel high-performance ...
  • On optimality and construction of circular repeated-measurements designs 

    Bailey, Rosemary Anne; Cameron, Peter Jephson; Filipiak, Katarzyna; Kunert, Joachim; Markiewicz, Augustyn (2017-01) - Journal article
    The aim of this paper is to characterize and construct universally optimal designs among the class of circular repeated-measurements designs when the parameters do not permit balance for carry-over effects. It is shown ...
  • Fertility preservation in pre-pubertal girls with cancer : the role of ovarian tissue cryopreservation 

    Wallace, W Hamish B; Kelsey, Thomas W; Anderson, Richard A (2016-01) - Journal article
    With increasing numbers of survivors of cancer in young people future fertility and ovarian function are important considerations that should be discussed before treatment commences. Some young people, by nature of the ...
  • Estimability of variance components when all model matrices commute 

    Bailey, Rosemary Anne; Ferreira, Sandra S.; Ferreira, Dario; Nunes, Celia (2016-03-01) - Journal article
    This paper deals with estimability of variance components in mixed models when all model matrices commute. In this situation, it is well known that the best linear unbiased estimators of fixed effects are the ordinary least ...
