Exceptional Vertex Operator Algebras and the Virasoro Algebra
(2008)We consider exceptional vertex operator algebras for which particular Casimir vectors constructed from the primary vectors of lowest conformal weight are Virasoro descendants of the vacuum. We discuss constraints on these ... 
Exceptionally bright TEV flares from the binary LS I+61 degrees 303
(IOP Publishing, 20160120)The TeV binary system LS I +61 degrees 303 is known for its regular, nonthermal emission pattern that traces the orbital period of the compact object in its 26.5 day orbit around its B0 Ve star companion. The system ... 
Expansions of CAG·CTG repeats in immortalized human astrocytes.
(Oxford University Press, 2007)Expansions of trinucleotide repeats (TNRs) are the genetic cause for a number of neurodegenerative disorders. In some of these diseases, ongoing somatic expansions in the brain are thought to contribute to disease progression. ... 
An experimental and kinetic modeling study of nhexane oxidation
(Elsevier, 20150911)Ignition delay times for nhexane oxidation have been measured in a rapid compression machine (RCM) at stoichiometric conditions and at 15 bar. Due to the high reactivity of nhexane and nonideal experimental effects ... 
Experimental and kinetic modeling study of the shock tube ignition of a large oxygenated fuel: tripropylene glycol monomethyl ether
(Elsevier, 20150513)Tripropylene glycol monomethyl ether (TPGME) is an important oxygenated fuel additive that can be used to reduce soot in diesel engines. However, a validated chemical kinetic model that incorporates the low to hightemperature ... 
Experimental characterisation of neural tissue at collision speeds
(International Research Council on Biomechanics of Injury (IRCOBI), 2012)Mechanical characterisation of brain tissue at high loading velocities is particularly important for modelling Traumatic Brain Injury (TBI). During severe impact conditions, brain tissue experiences a mixture of compression, ... 
Explicit secular equation for Scholte waves over a monoclinic crystal
(Elsevier, 2004)Scholte waves are acoustic waves propagating at a fluid/solid interface. They are localized in the neighborhood of the phase boundary in the sense that they decay exponentially in both directions along the normal to the ... 
The explicit secular equation for surface acoustic waves in monoclinic elastic crystals
(Acoustical Society of America, 20010125)The secular equation for surface acoustic waves propagating on a monoclinic elastic halfspace is derived in a direct manner, using the method of first integrals. Although the motion is at first assumed to correspond to ... 
Explicit secular equations for piezoacoustic surface waves: Rayleigh modes
(American Institute of Physics, 20050906)The existence of a twopartial Rayleigh wave coupled to an electrical field in 2 mm piezoelectric crystals is known but has rarely been investigated analytically. It turns out that the Z cut X propagation problem can be ... 
Explicit secular equations for piezoacoustic surface waves: Shearhorizontal modes
(AIP Publishing, 20050906)The existence of a twopartial Rayleigh wave coupled to an electrical field in 2 mm piezoelectric crystals is known but has rarely been investigated analytically. It turns out that the Z cut X propagation problem can be ... 
Extreme softness of brain matter in simple shear
(Elsevier, 20150313)We show that porcine brain matter can be modelled accurately as a very soft rubberlike material using the MooneyRivlin strain energy function, up to strains as high as 60%. This result followed from simple shear experiments ... 
A Fbridged Mn(II) molecular square
(RSC, 20091008)We report on a tetranuclear Mn(II) complex possessing a Fbridged molecular square topology directed by 1,10phenanthroline ligands. 
A family of doublebowl pseudo metallocalix[6]arene discs
(RSC, 20100310)We report the synthesis and magnetic characterisation of a series of planar [M7] (M = NiII, ZnII) disc complexes [Ni7(OH)6(L1)6](NO3)2 (1), [Ni7(OH)6(L1)6](NO3)2·2MeOH (2), [Ni7(OH)6(L1)6](NO3)2·3MeNO2 (3), [Ni7(OH)6(L2) ... 
Features and purposes of mathematical proofs in the view of novice students: observations from proof validation and evaluation performances
(20101222)This thesis describes a comprehensive exploratory study of the approaches taken by novice students to the validation and evaluation of mathematical proofs. A theoretical framework based on sociocultural learning theories ... 
Ferromagnetic exchange in a twisted, oximebridged [Mn(III)2] dimer
(Royal Society of Chemistry, 20120502)The dimeric complex [MnIII2(Naphthsao)2(NaphthsaoH)2(MeOH)2][middle dot]4MeOH (1[middle dot]4MeOH), acts as a simple model complex with which to examine the magnetostructural relationship in polymetallic, oximebridged ... 
Finite amplitude elastic waves propagating in compressible solids
(2005)The paper studies the interaction of a longitudinal wave with transverse waves in general isotropic and unconstrained hyperelastic materials, including the possibility of dissipation. The dissipative term chosen is similar ... 
Finite amplitude inhomogeneous waves in MooneyRivlin viscoelastic solids
(Elsevier, 200409)New exact solutions are exhibited within the framework of finite viscoelasticity. More precisely, the solutions correspond to finiteamplitude, transverse, linearly polarized, inhomogeneous motions superposed upon a finite ... 
Finiteamplitude inhomogeneous plane waves in a deformed MooneyRivlin material
(Oxford University Press, 2002)The propagation of finiteamplitude linearlypolarized inhomogeneous transverse plane waves is considered for a MooneyRivlin material maintained in a state of finite static homogeneous deformation. It is shown that such ... 
Finiteamplitude inhomogeneous plane waves of exponential type in incompressible elastic materials
(Kluwer Academic Publishers, 199905)It is proved that elliptically polarized finiteamplitude inhomogeneous plane waves may not propagate in an elastic material subject to the constraint of incompressibility. The waves considered are harmonic in time and ...
