    • Oblique wrinkles 

      Carfagna, M.; Destrade, Michel; Gower, Artur L.; Grillo, A. (The Royal Society Publishing, 2017-04-03)
      We prove theoretically that when a soft solid is subjected to an extreme deformation, wrinkles can form on its surface at an angle that is oblique to a principal direction of stretch. These oblique wrinkles occur for a ...
    • Observation of Extended VHE Emission from the Supernova Remnant IC 443 with VERITAS 

      Lang, Mark; Gillanders, Gary (2009)
      We present evidence that the very-high-energy (VHE, E > 100 GeV) gamma-ray emission coincident with the supernova remnant IC 443 is extended. IC 443 contains one of the best-studied sites of supernova remnant/molecular ...
    • Observation of gamma-ray emission from the galaxy M87 above 250 GeV with VERITAS 

      Lang, Mark; Gillanders, Gary (2008)
      The multiwavelength observation of the nearby radio galaxy M87 provides a unique opportunity to study in detail processes occurring in Active Galactic Nuclei from radio waves to TeV gamma-rays. Here we report the detection ...

      Lang, Mark; Gillanders, Gary (2010)
      We report on observations of very high-energy gamma rays from the shell-type supernova remnant Cassiopeia A with the VERITAS stereoscopic array of four imaging atmospheric Cherenkov telescopes in Arizona. The total exposure ...

      Lang, Mark; Gillanders, Gary (2006)
      We report on observations of the sky region around the unidentified TeV gamma-ray source TeV J2032+4130 carried out with the Whipple Observatory 10 m atmospheric Cherenkov telescope for a total of 65.5 hrs between 2003 and ...
    • Occupational exposures in an equestrian centre to respirable dust and respirable crystalline silica 

      Bulfin, Kathleen; Cowie, Hilary; Galea, Karen S.; Connolly, Alison; Coggins, Marie Ann (MDPI, 2019-09-03)
      Abstract: Sand-based products are regularly used as footing material on indoor equestrian arenas, creating a potential occupational exposure risk for respirable crystalline silica (RCS) for equestrian workers training and ...
    • Old dog, new tricks: 2,2'-biphenol as a bridging and book-end ligand in discrete and extended Co(II) architectures 

      Berg, Nelly; Jones, Leigh F. (RSC, 2012-02-01)
      We report the first Co(ii) based discrete and extended network materials comprising the 2,2[prime or minute]-biphenol ligand. We first present the synthesis and magnetic characterisation of the Co(ii) dinuclear complexes ...
    • On a question of Serre 

      Rahm, Alexander D. (2012)
      Consider an imaginary quadratic number field Q(root -m), with m a square-free positive integer, and its ring of integers {O} . The Bianchi groups are the groups SL2{O}. Further consider the Borel-Serre compactification [7] ...
    • On anisotropic elasticity and questions concerning its Finite Element implementation 

      Vergori, Luigi; Destrade, Michel; McGarry, Patrick; Ogden, Ray W. (Springer, 2013-05-21)
      We give conditions on the strain-energy function of nonlinear anisotropic hyperelastic materials that ensure compatibility with the classical linear theories of anisotropic elasticity. We uncover the limitations associated ...
    • On deforming a sector of a circular cylindrical tube into an intact tube: Existence, uniqueness, and stability 

      Destrade, Michel (Elsevier, 2010-11)
      Within the context of finite deformation elasticity theory the problem of deforming an open sector of a thick-walled circular cylindrical tube into a complete circular cylindrical tube is analyzed. The analysis provides a ...
    • On exceptional vertex operator (Super) algebras 

      Tuite, Michael P.; Van, Hoang Dinh (Springer, 2014-10-01)
      We consider exceptional vertex operator algebras and vertex operator superalgebras with the property that particular Casimir vectors constructed from the primary vectors of lowest conformal weight are Virasoro descendents ...
    • On Genus Two Riemann Surfaces Formed from Sewn Tori 

      Mason, Geoffrey; Tuite, Michael P. (2006)
      We describe the period matrix and other data on a higher genus Riemann surface in terms of data coming from lower genus surfaces via an explicit sewing procedure. We consider in detail the construction of a genus two Riemann ...
    • 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 ...
