    • On Level One Cuspidal Bianchi Modular Forms 

      Rahm, Alexander D. (2013)
      In this paper, we present the outcome of vast computer calculations, locating several of the very rare instances of level one cuspidal Bianchi modular forms that are not lifts of elliptic modular forms.
    • On magneto-acoustic waves in finitely deformed elastic solids 

      Destrade, Michel (SAGE Journals, 2011)
      In this paper, in the context of the quasi-magnetostatic approximation, we examine incremental motions superimposed on a static finite deformation of a magneto-elastic material in the presence of an applied magnetic field. ...
    • On reflection subgroups of finite Coxeter groups 

      Douglass, J. Matthew; Pfeiffer, Götz; Röhrle, Gerhard (Taylor & Francis, 2013-06-14)
      Let W be a finite Coxeter group. We classify the reflection subgroups of W up to conjugacy and give necessary and sufficient conditions for the map that assigns to a reflection subgroup R of W the conjugacy class of its ...
    • On residual stresses and homeostasis: an elastic theory of functional adaptation in living matter 

      Ciarletta, Pasquale; Destrade, Michel; Gower, Artur L. (Nature Publishing Group, 2016-04-26)
      Living matter can functionally adapt to external physical factors by developing internal tensions, easily revealed by cutting experiments. Nonetheless, residual stresses intrinsically have a complex spatial distribution, ...
    • On stress-dependent elastic moduli and wave speeds 

      Destrade, Michel; Ogden, R.W. (Oxford University Press, 2013)
      On the basis of the general non-linear theory of a hyperelastic material with initial stress, initially without consideration of the origin of the initial stress, we determine explicit expressions for the stress-dependent ...
    • On stress-dependent elastic moduli and wave speeds 

      Destrade, Michel (Oxford Journals, 2012-03-30)
      On the basis of the general non-linear theory of a hyperelastic material with initial stress, initially without consideration of the origin of the initial stress, we determine explicit expressions for the stress-dependent ...
    • On the Abaqus FEA model of finite viscoelasticity 

      Destrade, Michel (American Chemical Society, 2009-05)
      Predictions of the QLV (Quasi-Linear Viscoelastic) constitutive law are compared with those of the ABAQUS viscoelastic model for two simple motions in order to highlight, in particular, their very different dissipation ...
    • On the complexity of multiplication in the Iwahori-Hecke algebra of the symmetric group 

      Niemeyer, Alice C.; Pfeiffer, Götz; Praeger, Cheryl E. (Elsevier, 2016-09-12)
      We present new efficient data structures for elements of Coxeter groups of type Am and their associated Iwahori Hecke algebras H(A(m)). Usually, elements of H(A(m)) are represented as simple coefficient list of length M = ...
    • On the composition product of saturated fusion systems 

      Park, Sejong (Elsevier, 2011-11)
      We say that a fusion system is the composition product of two subsystems if every morphism can be factored as a morphism in one fusion system followed by a morphism in the other. We establish a relationship between the ...
    • On the equivariant K-homology of PSL_2 of the imaginary quadratic integers 

      Rahm, Alexander D. (Association des Annales de l'Institut Fourier, 2016-09)
      We establish formulae for the part due to torsion of the equivariant $K$-homology of all the Bianchi groups (PSL$_2$ of the imaginary quadratic integers), in terms of elementary number-theoretic quantities. To achieve this, ...
    • On the quiver presentation of the descent algebra of the symmetric group 

      Bishop, Marcus; Pfeiffer, Götz (Elsevier, 2013-03-18)
      We describe a presentation of the descent algebra of the symmetric group G(n) as a quiver with relations. This presentation arises from a new construction of the descent algebra as a homomorphic image of an algebra of ...
    • On the rectilinear shear of compressible and incompressible elastic slabs 

      Destrade, Michel (2010)
      We review some pseudo-planar deformations for the equations of incompressible isotropic nonlinear elasticity first introduced in 1985 by Rajagopal and Wineman. We extend this class of deformations to compressible isotropic ...
    • On the table of marks of a direct product of finite groups 

      Masterson, Brendan; Pfeiffer, Götz (Elsevier, 2017-12-28)
      We present a method for computing the table of marks of a direct product of finite groups. In contrast to the character table of a direct product of two finite groups, its table of marks is not simply the Kronecker product ...
    • On the third- and fourth-order constants of incompressible isotropic elasticity. 

      Destrade, Michel (Acoustical Society of America, 2010-04-25)
      Consider the constitutive law for an isotropic elastic solid with the strain-energy function expanded up to the fourth order in the strain and the stress up to the third order in the strain. The stress-strain relation can ...
    • On the Torus degeneration of the genus two partition function 

      Hurley, Donny; Tuite, Michael P. (World Scientific Publishing, 2013-07-16)
      We consider the partition function of a general vertex operator algebra V on a genus two Riemann surface formed by sewing together two tori. We consider the non-trivial degeneration limit where one torus is pinched down ...
    • Onset of non-linearity in the elastic bending of blocks 

      Destrade, Michel; Gilchrist, Michael D. (American Society of Mechanical Engineers, 2013-01-25)
      The classical flexure problem of non-linear incompressible elasticity is revisited assuming that the bending angle suffered by the block is specified instead of the usual applied moment. The general moment-bending angle ...
    • Phase behaviour of self-assembled monolayers controlled by tuning physisorbed and chemisorbed states: A lattice-model view 

      Cheung, David L. (American Institute of Physics, 2016-04-07)
      The self-assembly of molecules on surfaces into 2D structures is important for the bottom-up fabrication of functional nanomaterials, and the self-assembledstructure depends on the interplay between molecule-molecule ...
    • Piezoacoustic wave spectra using improved surface impedance matrix: Application to high impedance-contrast layered plates 

      Destrade, Michel (2008)
      Starting from the general modal solutions for a homogeneous layer of arbitrary material and crystalline symmetry, a matrix formalism is developed to establish the semianalytical expressions of the surface impedance matrices ...
    • Piezoelectric Love waves on rotated Y-cut mm2 substrates 

      Destrade, Michel (IEEE, 2006-11)
      Consider a layer consisting of a m3m dielectric crystal, with faces cut parallel to a symmetry plane. Then bond it onto a semi-infinite mm2 piezoelectric substrate. For an X- or Y-cut of the substrate, a Love wave can ...
    • 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 ...
