Nonlinear response and axisymmetric wave propagation in functionally graded soft electro-active tubes
(Elsevier, 2020-10-02)Soft electro-active (SEA) materials can be designed and manufactured with gradients in their material properties, to modify and potentially improve their mechanical response in service. Here, we investigate the nonlinear ... -
Nonlinear transverse waves in deformed dispersive solids
(Elsevier, 2008)We present a phenomenological approach to dispersion in nonlinear elasticity. A simple, thermomechanically sound, constitutive model is proposed to describe the (non-dissipative) properties of a hyperelastic dispersive ... -
North Eastern Atlantic cephalopods stock assessment in a data limited framework Surplus Production in a Continuous Time (SPiCT): Annex1to WP.4.2deliverable
(Cephs and Chefs (Interreg Atlantic Area Community Engagement Publications), 2021)The lack of management leaves fishery resources vulnerable to increases in fishing pressure.Although some cephalopods are of commercial importance, most of Northeast Atlantic stocks are non-quota ... -
A note about waves in dissipative and dispersive solids
(World Scientific, 2008)We study shear waves propagating in a special viscoelastic model proposed first by Fosdick and Yu in 1996. We deduce an asymptotic approximation which reduces the full balance equations to a system of evolution equations ... -
A note on element centralizers in finite Coxeter groups
(De Gruyter, 2011-08-29)The normalizer N-W(W-J) of a standard parabolic subgroup W-J of a finite Coxeter group W splits over the parabolic subgroup with complement N-J consisting of certain minimal length coset representatives of W-J in W. In ... -
Novel approach for label free super-resolution imaging in far field
(Nature Publishing Group, 2015)Progress in the emerging areas of science and technology, such as bio- and nano-technologies, depends on development of corresponding techniques for imaging and probing the structures with high resolution. Recently, the ... -
Novel Multiplex Real-Time PCR Diagnostic Assay for Identification and Differentiation of Mycobacterium tuberculosis, Mycobacterium canettii, and Mycobacterium tuberculosis Complex Strains
(Journal of Clinical Microbiology, 2011-02)Tuberculosis (TB) in humans is caused by members of the Mycobacterium tuberculosis complex (MTC). Rapid detection of the MTC is necessary for the timely initiation of antibiotic treatment, while differentiation between ... -
A Novel Multiplex Real-Time PCR for the Identification of Mycobacteria Associated with Zoonotic Tuberculosis
(PLoS ONE, 2011-08-09)Background: Tuberculosis (TB) is the leading cause of death worldwide from a single infectious agent. An ability to detect the Mycobacterium tuberculosis complex (MTC) in clinical material while simultaneously differentiating ... -
Numerical study on the minimum ignition energy of a methane-air mixture
(Elsevier, 2020-09-28)In this paper, a semi-detailed mechanism is used to calculate the minimum ignition energy (MIE) of methane-air mixtures, with all calculations conducted using ANSYS Fluent software. Ignition behaviors between success and ... -
Oblique wrinkles
(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
(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
(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 ... -
Observations of the shell-type SNR Cassiopeia A at TeV energies with VERITAS
(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 ... -
Observations of the Unidentified TeV Gamma-Ray Source TeV J2032+4130 with the Whipple Observatory 10 m Telescope
(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
(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
(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
(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] ... -
