  • Selection shapes synonymous stop codon use in mammals 

    Seoighe, Cathal; Kiniry, Stephen J.; Peters, Andrew; Baranov, Pavel V.; Yang, Haixuan (Springer (part of Springer Nature), 2020-07-02)
    Phylogenetic models of the evolution of protein-coding sequences can provide insights into the selection pressures that have shaped them. In the application of these models synonymous nucleotide substitutions, which do not ...
  • Stability analysis of charge-controlled soft dielectric plates 

    Conroy Broderick, Hannah; Righi, Michele; Destrade, Michel; Ogden, Ray W. (Elsevier, 2020-04-06)
    We examine the stability of a soft dielectric plate deformed by the coupled effects of a mechanical pre-stress applied on its lateral faces and an electric field applied through its thickness under charge control. The ...
  • Lower bounds on the non-Clifford resources for quantum computations 

    Beverland, Michael; Campbell, Earl; Howard, Mark; Kliuchnikov, Vadym (IOP Publishing, 2020-05-28)
    Treating stabilizer operations as free, we establish lower bounds on the number of resource states, also known as magic states, needed to perform various quantum computing tasks. Our bounds apply to adaptive computations ...
  • Global and local tests to assess stationarity of Markov transition models 

    Rodrigues de Lara, Idemauro Antonio; Hinde, John; Taconeli, Cesar Augusto (Taylor & Francis, 2018-02-09)
    We present global and local likelihood-based tests to evaluate stationarity in transition models. Three motivational studies are considered. A simulation study was carried out to assess the performance of the proposed ...
  • A Weibull-count approach for handling under- and overdispersed longitudinal/clustered data structures 

    Luyts, Martial; Molenberghs, Geert; Verbeke, Geert; Matthijs, Koen; Ribeiro Jr, Eduardo E.; Demétrio, Clarice G. B.; Hinde, John (SAGE Publications, 2018-07-30)
    A Weibull-model-based approach is examined to handle under- and overdispersed discrete data in a hierarchical framework. This methodology was first introduced by Nakagawa and Osaki (1975, IEEE Transactions on Reliability, ...
  • Models for overdispersed data in entomology 

    Demétrio, Clarice G. B.; Hinde, John; Moral, Rafael A. (Springer, Cham, 2014-09-17)
    Entomological data are often overdispersed, characterised by a larger variance than assumed by simple standard models. It is important to model overdispersion properly in order to avoid incorrect and misleading inferences. ...
  • Simulation of quantum circuits by low-rank stabilizer decompositions 

    Bravyi, Sergey; Browne, Dan; Calpin, Padraic; Campbell, Earl; Gosset, David; Howard, Mark (Verein zur Förderung des Open Access Publizierens in den Quantenwissenschaften, 2019-09-02)
    Recent work has explored using the stabilizer formalism to classically simulate quantum circuits containing a few non-Clifford gates. The computational cost of such methods is directly related to the notion of s t a ...
  • Prescribing patterns in growing tubular soft matter by initial residual stress 

    Du, Yangkun; Lü, Chaofeng; Liu, Congshan; Han, Zilong; Li, Jian; Chen, Weiqiu; Qu, Shaoxing; Destrade, Michel (Royal Society of Chemistry, 2019-10-02)
    Initial residual stress is omnipresent in biological tissues and soft matter, and can affect growth-induced pattern selection significantly. Here we demonstrate this effect experimentally by letting soft tubes grow in the ...
  • Tension lines of the skin 

    Ní Annaidh, Aisling; Destrade, Michel (Springer, Cham, 2019-05-29)
    Skin tension lines are natural lines of tension that occur within the skin as a result of growth and remodeling mechanisms. Researchers have been aware of their existence and their surgical implications for over 150 years. ...
  • Generalization of the Zabolotskaya equation to all incompressible isotropic elastic solids 

    Destrade, Michel; Pucci, Edvige; Saccomandi, Giuseppe (The Royal Society, 2019-07-03)
    We study elastic shear waves of small but finite amplitude, composed of an anti-plane shear motion and a general in-plane motion. We use a multiple scales expansion to derive an asymptotic system of coupled nonlinear ...
  • Multi-sector approximation method for arteries: the residual stresses of circumferential rings with non-trivial openings 

    Sigaeva, Taisiya; Destrade, Michel; Di Martino, Elena S. (The Royal Society, 2019-07-24)
    The opening angle method is a popular choice in biomechanics to estimate residual stresses in arteries. Experimentally, it means that an artery is cut into rings; then the rings are cut axially or radially allowing them ...
  • Poynting effect of brain matter in torsion 

    Balbi, Valentina; Trotta, Antonia; Destrade, Michel; Annaidh, Aisling Ni (Royal Society of Chemistry, 2019-06-13)
    We investigate experimentally and model theoretically the mechanical behaviour of brain matter in torsion. Using a strain-controlled rheometer, we perform torsion tests on fresh porcine brain samples. We quantify the torque ...
  • Influence of initial residual stress on growth and pattern creation for a layered aorta 

    Du, Yangkun; Lü, Chaofeng; Destrade, Michel; Chen, Weiqiu (Nature Research, 2019-06-03)
    Residual stress is ubiquitous and indispensable in most biological and artificial materials, where it sustains and optimizes many biological and functional mechanisms. The theory of volume growth, starting from a stress-free ...
  • Rivlin's legacy in continuum mechanics and applied mathematics 

    Destrade, Michel; Murphy, Jeremiah; Saccomandi, Giuseppe (The Royal Society, 2019-03-18)
    Over a long and distinguished career, Ronald Rivlin (figure 1) published more than 200 scientific papers. He was a highly innovative scientist who made seminal contributions in all areas of continuum mechanics. He was one ...
  • Tuning the pull-in instability of soft dielectric elastomers through loading protocols 

    Su, Y.P.; Chen, W.Q.; Destrade, Michel (Elsevier, 2019-03-22)
    Pull-in (or electro-mechanical) instability occurs when a drastic decrease in the thickness of a dielectric elastomer results in electrical breakdown, which limits the applications of dielectric devices. Here we derive the ...
  • Wrinkles in soft dielectric plates 

    Su, Yipin; Conroy Broderick, Hannah; Chen, Weiqiu; Destrade, Michel (Elsevier, 2018-07-04)
    We show that a smooth giant voltage actuation of soft dielectric plates is not easily obtained in practice. In principle one can exploit, through pre-deformation, the snap-through behavior of their loading curve to deliver ...

    Zurlo, Giuseppe; Destrade, Michel; Lu, Tongqing (AIP Publishing, 2018-10-16)

    Cinelli, Ilaria; Destrade, Michel; McHugh, Peter; Duffy, Maeve (Wiley, 2018-06-16)
